Leakage detection assembly and system

This application claims the priority of US Provisional Application No. 61/355, 468, filed June 16, 2010, and incorporates the full text of that application here by citation. This disclosure relates to equipment, systems, and methods related to the monitoring and control of infrastructure, including, but not limited to, the supply and use of commercial, industrial, or household water, gas, and / or electricity. In particular, it relates to devices, methods, and systems that monitor and control municipalities and warn users of possible failures and necessary actions.

Municipalities operate and / or outsource a number of utilities and safety systems within each municipality. Such systems are usually complex infrastructures, including but not limited to water distribution, gas distribution, power distribution, water management, traffic control, fire departments, police stations, and emergency response departments. Each of these systems needs to be monitored for use (permitted or unauthorized), failure, mischief, events, obstruction or blockage, leaks, contamination, and / or other issues.

To keep track of the status of either system, or for normal use, billing or repair, personnel dispatched to the municipality usually have to manually check for problems in the system. This system is time consuming, labor intensive and can be overlooked. In addition, favorable aspects of the system are evaluated on an irregular or rare basis, leaving problems unchecked for long periods of time. For example, if there is a leak in the water main, especially if the leak is not detected for a relatively long period of time, the water company will incur high costs for lost water, energy consumption, chemical treatment and so on. In addition, leaks can cause structural corrosion underground. Interference with the system can go unnoticed unless reported to the central location.

Another problem or drawback associated with current systems is the system for utilities that maintain and monitor networks of monitor and device controllers that can generate transmission infrastructure that can be adapted to multiple monitors and controllers. There is a lack of sufficient property rights to form an information network that provides information. For example, some networks require the installation of new utility poles and towers for the placement of communication devices. Municipalities may have to rent space on utility poles for utility companies to install such equipment.

In addition, problems in one system can cause problems in another system. For example, when a fire is reported to the fire department, it may be necessary for the gas company to block the gas flow to the vicinity of the fire and the water company to redirect water or additional water pressure to the vicinity. However, many current systems lack interoperability.

As embodied and outlined herein, the present disclosure provides exemplary embodiments of the disclosed systems, methods, and devices. The features can be embodied in various alternative shapes. Therefore, the specific structural and functional details are not intended to be limited and are representative for teaching the basis of a claim how those skilled in the art will adopt the invention in various ways. It is intended to be provided as a basic foundation.

A problem that can be solved by the disclosed embodiments is infrastructure monitoring and maintenance. A monitoring device with one-way or two-way communication capabilities can be used to detect failures in municipal systems and provide real-time or near-real-time device status, maintenance, and system control on demand. Was discovered.

The network of monitoring devices can provide the system administrator with an overview of the current state of the system. The network includes an array of various monitoring devices, each capable of sensing at least one condition. The monitoring device can send and receive data to and from at least one operation center. Communication from the remote monitoring device is a central monitoring facility Can be directed to one of a number of regional surveillance centers, users, and / or research facilities. Further, the system includes at least one control device. Each controller is configured to control various situations in the system. The control device may be part of a monitoring device or may be a separate unit. Communication is via the Internet, but may be via a private network, a private network, or a wide area network. Communication includes wireless elements, such as from remote monitoring equipment and / or control equipment to regional monitoring facilities or distributed monitors. Communication is also protected or encrypted so that the communication system cannot be monitored by another unknown person. Access to the system is allowed by the user's name and password, but additional and / or alternative encryption methods can be adopted.

One embodiment relates to a water infrastructure system. In such a system, the monitoring device may be placed throughout the system, for example, as an accessory to a component, for feedback to the network that can provide real-time information to the utility company operating the network. The network operator can use the transmitted information to activate controls on the network or dispatch repairs or other services as directed by the information provided by the network. .. For example, if a water pressure monitor on a water meter shows a variation between positions, a network can be used to report a leak and the controller can transfer the water. By attaching a pressure gauge to the hydrant to monitor and report pressure loss throughout the system, hydrant users (fire departments that need to ensure adequate pressure), system users (waterworks affected by pressure drops) Consumers), and system operators (who suffer property losses as a result of the lack of real-time information about losses) can be provided with real-time information.

FIG. 1 shows a system 100 of the invention that monitors, controls, and / or communicates with at least one monitoring device and / or at least one control device. The system 100 includes an operation center 105 that communicates with at least one monitoring device 110 and / or one control device 111. In a preferred embodiment, bidirectional communication between the operation center 105 and the devices 110 and 111 is possible. Communication may be unidirectional or bidirectional. Communication is wired network, wireless network, ZIGBEE (registered trademark) network, BLUETOOTH (registered trademark) network, Z-wave network, WiFi network, WiMax network, RF network, premises network (LAN), Internet network, wide area network (WAN). ), Mobile phone networks, fixed-wire phone networks, 900 MHz wireless networks, and satellite networks, but not limited to any communication network 115 known in the art. In one embodiment, the network is a fixed network. For example, the fixed network can be a mesh network or a star network. The devices 110 and 111 and the operation center 105 can also communicate directly or through relay devices such as relays, repeaters, gateways, or other devices capable of receiving and retransmitting messages.

Each monitoring device 110 of the present invention monitors the status of at least one of the infrastructures. The statuses monitored are infrastructure elements (eg, pipe status, valve status, fire plug status, service line status, meter status, transmission line status, and battery status), commercial status (eg, liquid). Alternatively, it can be one or more of a gas stream, a liquid or gas pressure, a liquid or gas temperature, and a liquid or gas contamination), or a combination thereof. Further, each monitoring device 110 can monitor itself. For example, the monitoring device 110 determines if there is communication loss, low battery level, and / or internal damage (eg, a short circuit due to flood damage). Further, each monitoring device 110 is structurally fixed (for example, a valve, a pipe, a utility pole, a fire hydrant, a valve box, a valve box cover, a meter, a meter box). Fixed to a water tower, water tower, water tank, pumper nozzle, hose nozzle, or manhole cover) or made movable (for example, with or in a water or gas stream in a pipe) Can be moved).

For example, the monitoring device 110 or 111 can be coupled to the hydrant 405 as shown in FIG. 4B. The monitoring device 110 or 111 may be mounted within the nozzle cap 600 (ie, within the pumper nozzle, hose nozzle, or fire engine hookup), inside the hydrant body, inside the bonnet, outside the hydrant, or on or inside the hydrant. Can be placed in place. The housing for the monitoring device 110 or 111 is made of plastic, nylon, other synthetic or natural material, or other material that does not block communication with the monitoring device 110 or 111. For example, as shown in FIG. 4A, the fire hydrant bonnet 400 can include a monitoring device 110 and a waterproof container 420 for the monitoring device 110. In certain embodiments, the hydrant bonnet 400 can also include a power supply 425. In another example, as shown in FIG. 4B, the monitoring device 110 may be coupled to the outside of the fire hydrant 405. In another embodiment shown in FIGS. 5A and 5B, the bonnet 500 of the hydrant 505 can be isolated from the water stream within the hydrant 505. For example, a disc 530 of plastic, metal, or other material that seals a portion of the hydrant 505 can be provided to prevent water from reaching the internal area of the bonnet 500.

In another embodiment, the monitoring device 110 or the control device 111 is located within the nozzle cap 600 of the fire hydrant. The nozzle cap 600 of the fire hydrant is a device that is attached to the outlet nozzle and covers the opening of the nozzle. The nozzle cap 600 is equipped with a nut 605 or other device that allows the nozzle cap 600 to be firmly attached to the outlet nozzle or to apply a force to remove the nozzle cap 600 from the outlet nozzle. FIG. 6A is an isometric view of an embodiment of the nozzle cap 600. In one embodiment, the nozzle cap 600 consists of a composite material, plastic, nylon, other synthetic or natural material, or other material that does not block transmission from the monitoring device 110 or control device 111. The material has the same fading properties as the paint used on the outside of the fire hydrant. For example, the material can have the same resistance as the paint to water, UV rays, corrosion, oxidation and other causes of fading. Therefore, it seems that the paint and the nozzle cap 600 are made of the same material.

6B and 6C are cut views of an embodiment of the nozzle cap 600. The nozzle cap 600 has a housing 610 that creates a cavity into which the monitoring device 110 or the control device 111 can be placed. The cavity is surrounded by a cover 615. The housing 610 and the cover 615 produce a watertight seal that can withstand water pressures in excess of 400 psi. In various embodiments, other pressures can be utilized. Further in one embodiment, the nozzle cap 600 has an antenna cover 620. The antenna cover 620 can be manufactured of the same material as or different from the nozzle cap 600. The position of the antenna should be kept away from metal for efficiency.

The nozzle fire hydrant screw 625 is provided as a means for connecting the nozzle cap 600 and the fire hydrant. The nozzle cap 600 also includes a female screw 630 that is a connecting means for connecting the housing 610 and the nozzle cap 600. The housing 610 also includes a male screw 640 designed to be coupled with a female screw 630. Antenna 650 is illustrated.

Each node of network 115 detects a transmission error. Error detection can be a cyclic redundancy check using a table based on a defined polynomial or other error detection method. In another embodiment, the route can be modified and transmitted if the primary route is blocked or otherwise unavailable. In addition, devices 110 and 111 can confirm receipt of the message, for example via a handshake protocol. .. If no confirmation is received, the message can be resent with the same route or with a different route.

In various embodiments, each monitoring device 110 and each control device 111 is assigned a unique identifier. The unique identifier can be associated with the geographic location, address, installation order of the device, or other method of identifying the devices 110, 111. Further, various types of devices 110 and 111 can have a unique identifier including a unique key for each type of device. For example, WM can be attached to the identifier of all water meters, and LD can be attached to the identifier of all leak detectors. Each communication with the monitoring device 110 and the control device 111 also has a unique identifier so that the message can be received by the accurate monitoring device 110 or the control device 111, or the operation center 105 can determine where to send the message. Can be prepared.

Each monitoring device 110 and each control device 111 can be integrated into an existing system 100 or device 110, 111, can be coupled to a new system 100 or device 110, 111, or a new system 100 or device 110, 111. Can be integrated into. For example, the system 100 can operate with or without connection to a monitoring and control data collection system (SCADA) network. In one embodiment, each monitoring device 110 and each control device 111 has a set of adapters that simplifies the coupling of the monitoring device 110 or control device 111 with the new or existing system 100 or devices 110, 111.

In one embodiment, the system 100 is divided into sectors, each sector having at least one monitoring device 110 and / or at least one control device 111. Each sector may have direct communication with the operation center 105 or may have a monitoring device 110 and / or a control device 111 and at least one intermediary communication device communicating with the operation center 105. In one embodiment, the sectors are divided by geographic location. For example, all devices in a region are located within a single sector, with one sector per region. In one embodiment, one intermediary communication device can provide services to a plurality of sectors.

In another embodiment, each monitoring device 110 and / or control device 111 may communicate with an adjacent monitoring device 110 and / or control device 111. In such an embodiment, each monitoring device 110 and / or control device 111 acts as a transmitter / receiver, or receives and transfers a message addressed to another device 110, 111 or operation center 105. Can be relayed by. In the embodiment in which the system 100 is divided into sectors, the monitoring device 110 and the control device 111 can communicate only within the sector. In another embodiment, the monitoring device 110 and the control device 111 can communicate with the devices 110 and 111 in other sectors. Each monitoring device 110, control device 111, and / or operation center 105 can determine whether or not the transmitted message was received by the target 110, 111, and if not, the message is correctly received. You can redistribute the message until it is done. Further, by mounting the relay device in the system, the communication range can be further expanded. For example, relay devices can be placed on utility poles, in municipal buildings, in fire hydrants, and / or under manhole covers. In another embodiment, the devices 110 and 111 can communicate on a network. In a network, devices 110 and 111 can communicate with other devices 110 and 111 in the network. The operation center 105 can set a predetermined communication route obtained from the routing table.

The Operations Center 105 may be located in a municipal office, a private or state-owned enterprise, a fire department, a police station, or any other entity that monitors the Operations Center 105. In another embodiment, the operation center 105 can be a remote host and accessible via the Internet. In the above embodiment, the operation center 105 can utilize cloud computing (for example, a network of remote host computers, servers, and data storage devices). Compared to non-remote host computer networks, cloud computing can increase usability, improve access and security, reduce costs, and provide specially customized, unlimited storage space. Further, in various embodiments, a plurality of operation centers 105 are provided. One or more Operations Centers 105 can be located in different entities, and each Operations Center 105 can monitor different aspects of the System 100. For example, in an embodiment in which one monitoring device 110 monitors water usage and another monitoring device monitors gas leaks, the water usage status is monitored by the water company and the gas leaks are monitored by the gas company and / Or can be monitored by the fire department. In some embodiments, there are overlapping Operations Centers 105, with at least two Operations Centers 105 monitoring the same aspects of System 100. The operation center 105 can transmit a transmission that updates the firmware of the devices 110 and 111.

FIG. 2 is a schematic view of the monitoring device unit 200. The monitoring device unit 200 includes a processor 205. Processor 205 is coupled to at least one input port 210 that receives data from sensor 215. The processor 205 is also coupled to a transmitter / receiver 220 that transmits / receives signals. The processor 205 is coupled to the data storage unit 230. The data storage unit 230 can hold a predetermined amount of data received from the sensor 215. For example, the data storage unit 230 holds data for a predetermined time (for example, one day, one week, or one month), or holds a predetermined number of reads (for example, 10 reads, 100 reads, 1000 reads). Alternatively, the data can be retained until the operation center 105 instructs it to erase. Further, the data storage unit 230 can hold an instruction to the processor 205 to be executed at the time of prompting from the operation center 105. The processor 205 compiles to transmit at least a part of the data stored in the data storage unit 230 to the operation center 105.

Each monitoring unit 200 can continuously collect and / or transfer data at specific intervals or at random. In an embodiment in which the monitoring device unit 200 collects and transmits data discontinuously, the monitoring device unit 200 can cut or reduce power consumption during the non-data collection period to save energy. Processor 205 is coupled to power supply 235. The power supply 235 can be a unit capable of supplying power to the processor 205 and the devices mounted on the processor 205. For example, the power supply 235 can be a battery, a solar panel array, a wind turbine, a hydraulic turbine, an electric wire, or a combination thereof. In a preferred embodiment, there is also a backup power source such as a battery. Power can be obtained from the operation of system 100.

In one embodiment, the processor 205 is coupled to at least one sensor 215 that monitors at least one state associated with the monitoring device. The sensor 215 can determine the state of the device. The sensor 215 can transmit and receive signals from the processor 205 either by wiring directly to the processor 205 or by using wireless communication. The sensor 215 may be located inside or outside the monitoring device. In another embodiment, the sensor 215, the monitoring device or may be disposed et remotely. For example, the sensor can be placed inside a fire hydrant, in a nearby building, or on a utility pole. In an embodiment in which the sensor 215 and the processor 205 communicate wirelessly, the same communication protocol is used for the sensor / processor communication and the processor / operation center communication, or the sensor / processor communication and the processor / control center communication are used. It is possible to use different communication protocols with the communication. For example, sensor / processor communication can use the RF protocol and processor / control center communication can take place over a wireless network.

In one embodiment, the sensor 215 is a usage monitor. In the above embodiment, the usage monitor records the amount of water, gas, electricity, or other commodities used by the consumer for a predetermined period of time. The usage monitor can continuously record the usage of the product or provide a signal to the processor 205 that the product is in use. By transmitting a signal to the operation control device, the processor 205 can notify the operation center 105 that the monitoring device 110 is in use and / or how much goods are flowing through the sensor 215. The operations center can request a read from the usage monitor on demand. The processor 205 or the operation center 105 can determine whether or not there is unauthorized use of the goods based on the usage amount. Upon detection of unauthorized use, at least one of the processor 205 and the operation center 105 may issue a warning that unauthorized use exists. For example, in an embodiment in which the usage monitor is coupled to the fire hydrant 405, the usage monitor indicates that the fire hydrant 405 is in use, but if no fire is reported, the operation center 105 may misuse the fire hydrant 405. Can convey a warning that there is sex.

In various embodiments, at least one sensor 215 is a naughty sensor. Prank sensors include motion detectors, contact sensors, rotation sensors, touch sensors, proximity sensors, biofeedback sensors, temperature sensors, capacitance sensors, resistance sensors, or any other sensor capable of detecting the presence of an object. can do. The mischief sensor can send a message to the processor 205 when it detects an event. The processor 205 can then evaluate the event to determine if the monitored device has been tampered with, or relay a message to the operations center 105 for evaluation. The device to be monitored can be a fire hydrant, a supply and demand meter, a valve, a manhole cover, a pump, or any other device that can be tampered with. After detecting the mischief event, at least one of the processor 205 and the operation center 105 can issue a warning that the device has been mischievous. The monitoring device can start a tamper-proof device (described later). The operation center 105 sends a transmission instructing the processor 205 to ignore the message from the mischief sensor for a predetermined period of time or until another message telling the processor 205 to start monitoring the mischief event is received from the operation center 105. send. For example, if the fire department needs to use a fire hydrant, the Operations Center 105 sends a message to the Processor 205 to temporarily ignore the mischief event. Once the fire department has finished using the hydrant, the Operations Center 105 sends a message to the Processor 205 to resume monitoring for mischief events.

In certain embodiments, at least two of the sensors 215 are leak detectors. Each leak detector can include an in-pipe leak detector and / or an external leak detector. For gas applications, the leak detector is a vapor sensor. On the other hand, for liquid applications, the leak detector determines the presence and location of the leak by utilizing acoustic monitoring. The energy generated from the leak is transmitted into the pipe through the goods and the pipe wall. Each leak detector can detect vibrations caused by leaks in goods or pipe walls, connections, or service lines. To determine the location of a leak, at least two detectors must detect the same leak. Based on the speed of the voice transmitted along the pipe (V), the distance between the two detectors (D), and the delay between the time points when each detector detects the voice (T), the following formula is used. The leak position (L) can be determined.

L = (D- (VxT)) / 2 According to the above equation, the standard speed of sound in water is about 1500 m / s, and the standard speed of sound through an iron pipe is 5100 m / s. This speed can be measured experimentally. For example, if the leak is exactly in the middle between the two detectors, the audio will reach both detectors at the same time. Each detector can be monitored continuously or at regular intervals. The leak detector can send a message to the processor 205 when it detects an event. Processor 205 can then evaluate the event to determine if a leak is present and how serious the leak is, or relay a message to the Operations Center 105 for evaluation. Upon detection of a leak event, at least one of the processor 205 and the operation center 105 may issue a warning that a leak is present if the leak is determined to be alert enough.

In various embodiments, at least one sensor 215 is a smoke detector. The smoke detector can be a photoelectric detector, an ionization detector, or any other device capable of detecting the presence of smoke. The smoke detector can be located inside the monitoring device or outside the monitoring device. Smoke detectors continuously monitor smoke. The smoke detector can send a message to the processor 205 when it detects an event. The processor 205 can then determine if smoke is present by evaluating the event or relay the message to the operations center 105 for evaluation. Upon detection of smoke, at least one of the processor 205 and the operation center 105 can issue a warning that smoke is present.

In certain embodiments, the at least one sensor 215 is a temperature sensor. Temperature sensors can be contact sensors (eg thermometers, thermistas, glass thermometers, resistance temperature detectors, filling system thermometers, bimetal thermometers, semiconductor temperature sensors, and phase change indicators), or non-contact sensors (eg, phase change indicators). It can be a radiation thermometer, a thermal imaging device, a ratio thermometer, an optical thermometer, and an optical fiber thermometer). The temperature sensor may be located inside the monitoring device or outside the monitoring device. In one embodiment, the temperature sensor continuously monitors for temperatures above or below a predetermined threshold. When the temperature sensor detects a temperature exceeding the threshold value, it can send a message to the processor 205. The processor 205 can then evaluate the event to determine if its temperature is a problem (such as a pipe freeze or fire) or relay a message to the Operations Center 105 for evaluation. When detecting an undesired temperature, at least one of the processor 205 and the operation center 105 can issue a warning that an undesired temperature condition exists.

In various embodiments, at least one sensor 215 is a rust and / or corrosion sensor. Corrosion sensors use any method known in the art, including but not limited to liquid penetrant inspection, magnetic particle inspection, radiographic inspection, visual inspection, eddy current inspection, ultrasonography, and thermography inspection. This allows rust and / or corrosion to be detected. The corrosion sensor can send a message to the processor 205 when it detects rust or corrosion above the threshold. The processor 205 can then evaluate rust or corrosion to determine if there is a problem, or relay a message to the Operations Center 105 for evaluation. When detecting undesired rust or corrosion, at least one of the processor 205 and the operation center 105 can issue a warning that an undesired amount of rust or corrosion is present.

In various embodiments, at least one sensor 215 is a flow rate sensor. The flow sensor can be used in either a gas system or a liquid system. The flow sensor can detect flow direction, turbidity, flow velocity, flow density, flow viscosity, and / or any other flow conditions. Can be detected. The flow rate sensor is a speedometer, laser interferometer, vane, rotational potential meter, Hall effect sensor, device for measuring heat transfer caused by flowing fluid, or any other device known in the art for measuring fluid flow.

The ionization chamber dosimeter must be charged regularly and the results recorded. The film badge dosimeter must be developed as a photographic emulsion so that the exposure dose is counted and recorded. Once developed, it is discarded. Another type of dosimeter is a TLD (thermoluminescence dosimeter). These dosimeters contain crystals that emit visible light when heated, in direct proportion to total radiation exposure. Like ionization chamber dosimeters, thermoluminescent dosimeters can be reused after "reading". Geiger counters and scintillation counters directly measure the dose rate of ionizing radiation.

In various embodiments, there is also a backup power source such as a battery.

In various embodiments, at least one output device 340 is an actuator control device. The actuator control device can control any type of actuator including, but not limited to, a tamper-proof device, a locking device, a camera operating device, a fire hydrant nut opening device, or a valve. The actuator control device can control the actuator autonomously or in response to a request from the processor 305. For example, upon receiving a signal that a particular event has been detected, the processor 305 can instruct the actuator controller to operate in a particular way. Similarly, in certain embodiments, the control signal can be emitted from the operation center 105. Actuators can be mechanical, electrical, or a combination thereof.

In various embodiments, at least one output device 340 is an alarm. The alarm can be a visible alarm, an audible alarm, a tactile (ie, vibration) alarm, or a combination thereof. The alarm may be located inside the monitoring device, outside the monitoring device, at the operation center 105, remotely from the system, or at any other location sufficient to warn. In addition, two or more alarms can be placed in different locations. For example, in an embodiment with a smoke detector, an audible alarm is placed inside the fire detector to warn people around the monitoring device of the possibility of a fire, and an audible alarm is placed at the fire department to fire at the fire department. It can warn of the possibility of a fire and indicate that the gas flow in the vicinity of a possible fire should be blocked by placing a visual alarm in the gas company. In some embodiments, the alarm is controlled by the processor 305, while in other embodiments the alarm is controlled by the operation center 105. In various embodiments, the alarm has a locally controllable on / off switch.

Example: The system of this disclosure monitors the water distribution infrastructure. The system is used to automatically control the water pressure in the system. The above system provides usage information to the control center. Includes a number of water meters that are paid for throughout the infrastructure, relayed by Im. When the operation center determines that the system usage is low (eg, at night) based on the information received by a predetermined number of water meters, it reduces or stops the water supply that puts pressure on the system. This saves electricity used by the water supply while maintaining sufficient pressure across the infrastructure to meet water needs. The decision to reduce or stop water supply can also be based on information received from pressure sensors that are paying for the entire infrastructure. For example, when the pressure in the infrastructure exceeds the threshold, the operation center reduces or stops the water supply.

In another example, the system is used to help maintain the infrastructure. Since water pipes and valves are often embedded underground, it is difficult to locate the device, assess the condition of the device, and repair the device if necessary. Using the example system described above, each device is equipped with a monitoring device. The monitoring device can, for example, monitor corrosion by a corrosion monitor, geographical location by a GPS receiver, and leak by a leak detector. Upon detection of corrosion and / or leakage, the monitoring device sends a message to the Operations Center where the information is analyzed. The operation center should observe whether the corrosion and / or leak is serious enough to require repair, whether the corrosion and / or leak should be observed to determine deterioration, or whether the corrosion and / or leak is ignored. It can be determined whether or not it can be done. The Operations Center also warns personnel about the situation for further assessment.

If it is determined that corrosion and / or leaks should be repaired, the Operations Center will communicate that information to the repair personnel to keep the equipment out of the water. The information can include device location based on data received from GPS receivers, device related issues, device information (eg, manufacturer, model, and / or year) and the like. The monitoring device can also be equipped with an RFID transmitter that transmits at least a portion of the above information. The repairman receives the information on a smartphone, a portable computer, or any other device capable of receiving the above information. Upon completion of the repair, the Operations Center will update the system to display the new latest repair date for the equipment.

In another embodiment, the system is monitored simultaneously by several entities within the municipality. For example, fire departments, gas companies, water companies, power companies, and traffic control centers all monitor systems simultaneously. When the monitoring device detects smoke, the control center warns each entity of the possibility of a fire. The location of the fire is determined by cross-reference between the monitoring device ID number and the reference table, or based on the information received from the GPS receiver. The fire department dispatches emergency responders to the vicinity of a possible fire by using the location information. The gas company uses its location information to divert or block the gas flow to the vicinity of a possible fire. By using the location information, the water company diverts water toward the vicinity of a possible fire or raises the water pressure in the vicinity of a possible fire to obtain information received from a monitoring device attached to a fire hydrant. Based on this, determine if the hydrant in the vicinity of a possible fire may have been damaged (eg, tilted at an abnormal angle, under no or little water pressure, or tampered with). The position of the fire hydrant is determined by cross-reference between the monitoring device ID number and the reference table, or based on the information received from the GPS receiver. The water company automatically warns the fire department which hydrant to use. In addition, water companies deactivate tamper-proof devices associated with fire hydrants. Power companies increase the electrical load on water pumps by receiving signals that additional pressure is needed within the water system. In addition, traffic control centers help fire trucks arrive quickly and safely by adjusting traffic lights on the way from the fire department to the vicinity of possible fires.

In another embodiment the system is used to monitor contaminants in the fluid flowing through the system. The system includes pressure sensors, leak detectors, and contamination detectors. Leaks in the system cause a drop in pressure throughout the system, which can lead to contaminants being drawn into the system. For example, if the pipe is underwater and the pressure inside the pipe is lower than the pressure outside the pipe, the water outside will flow into the pipe. The system therefore has several monitoring devices for checking for such possible or actual contamination. The pressure sensor indicates whether the pressure in the system is below the threshold level that draws contaminants into the system. The leak detector indicates if there is a leak that could allow contaminants to enter the system. Contamination detectors indicate possible defects in the system infrastructure by indicating the presence or absence of contaminants in the system.
