DESCRIPTION
Intelligent energy saving system for rooms accessible with an ID card.
Field of the invention
The present invention relates to a room-oriented energy saving system in residential environments.
Background of the invention
Hotels currently have power disconnectors of different types. In the first place, the simple disconnectors, whose operation is to insert the room access card to act on a microswitch by weight or contact, and the room light and air conditioning are immediately activated. These systems can be tricked by inserting any card or cardboard that performs this function, while the guest leaves the room with the room access card that allows them to open the lock again, or by leaving the access card inserted. to your companion's room. When the client leaves the room (for example, for dinner), he can leave the card inserted in the power disconnect, so that the light and above all, the air conditioning remain on even if the client is outside, with the consequent waste of energy.
The alternative to these simple disconnects are smart disconnectors, with RFID microchips that verify that it is an authorized card - with a valid reservation or daily payments, without being a cleaning employee who usually have restricted telephone, minibar and heating uses. But these smart disconnects can also be tricked because the guest -especially in student residences, with long stays and most relevant energy expenses- introduces a valid RFID card to have their information and any other that acts as a switch by weight: the reader reads the chip of one and grants the assigned uses but does not check that information again because the "trap" card continues to activate the microswitch, with which the guest takes out the "good" card and leaves the other and all the devices consuming out of control.
Description of the invention
The system object of the present invention is designed to continuously monitor human movement in the room, in such a way that when it is detected that a maximum time has elapsed without movement in the room, despite the fact that the identification support is inserted into the control unit, the system automatically disconnects 35 items with the most electrical consumption in the room such as air conditioning, heating, etc.
The system is capable of controlling the opening of doors or windows to carry out the same action above, disconnect the elements with the highest electrical consumption in the room, at the same time it detects that a door or window has been opened.
Another feature of the system is the ability to preset a comfort temperature for the room while a person is not in it. Once a person is detected in the room, the temperature control becomes manual.
Finally, the system has the ability to view the status of the room, occupied or unoccupied, without the need to enter it.
The biggest advantage of the system is that it is a complete system that is completely compatible with all the 50 elements that make it up, the sensor elements are of very low consumption and are powered by batteries, so they do not need power cables and communications between the devices. Different devices that make up the system are wireless, so it is not necessary to install communications wiring.
Therefore, to try to solve the problems exposed to the intelligent power disconnector a wireless device is added to it so that it can communicate wirelessly with other devices. One of these devices is a wireless motion sensor. This equipment is a device that is installed on the ceiling, and includes a motion sensor, a wireless device and alkaline batteries for its power.
The operation is as follows:
- The client accesses the room.
- Insert the card into the power disconnect.
- The disconnect communicates wirelessly with the wireless motion sensor installed in the room and this sends it information on whether or not there is movement in the room.
- In case of movement, the disconnector will activate the corresponding light and air conditioning.
is 2 350 996 Al
- If there is no movement for x minutes (programmable), it will inform the disconnector that there is no one in the room even if the card is inserted in it. The motion sensor will poll for motion every x minutes (programmable).
In this way, this solution avoids the aforementioned problem, making the hotelier save energy in an important way.
Therefore, the system is designed to identify a person upon entering the room. For this, this person must use an identification support, which can be of different shapes and technologies, and insert it into a control unit 10. Once the person has been correctly identified, the control unit automatically switches on the lighting in the room and the additional services available in the room. As soon as this person removes their identifier from the control unit, a programmable timer starts, at the end of which the lighting and additional services are switched off.

Brief description of the drawings
A series of drawings that help to better understand the invention and that expressly relate to an embodiment of said invention which is presented as a non-limiting example of this, will now be described very briefly.
Figure 1 shows the components of the system object of the invention.
Description of a preferred embodiment of the invention
The system of the invention presents a set of devices that together allow to optimize the control and energy consumption of a room. The system is made up of the elements shown in Figure 1:
- a motion sensor and thermostat 1;
- an energy control unit 8;
- ID card 12;
- door / window sensors 15;
- optionally, a room status display 19.
The energy control unit 8 is capable of identifying the person entering the room by introducing the identification card 12, making the connection and disconnection of the room lighting and the different additional services available, such as such as air conditioning, heating, etc., receive and process the information from the different sensors that make up the system and act accordingly by activating or deactivating the elements with the highest energy consumption.
is 2 350 996 Al
The energy control unit 8 is powered from the electrical network and incorporates a power supply 9 that converts the voltage of the electrical network into direct voltage to power the different electronic circuits. It also incorporates a series of power relays 11 that make it possible to connect and disconnect the different loads that are connected to the control unit 8. Loads are understood to mean the different additional services available to the room. In addition, it must process the information from the identification card 12 of the person entering the room using a support read / write module 10 that may vary depending on the type of support used in each case among the different technologies available ( magnetic stripe card, contact chip card or smartcard, proximity card or RFID transponder support according to ISO14443A & B, ISO15693, NFC device). Finally, it incorporates a wireless communications module 7 that allows the control unit 10 8 to receive and send information wirelessly to the different sensors. It is wireless communication according to the IEEE802.15.4 2.4 Ghz standard. It allows to achieve distances of about 15 m in residential environments inside buildings.
The motion sensor and thermostat 1 is an element capable of measuring or detecting two parameters, one is the movement of a person in the room and the other is the ambient temperature of the room. It is a zenith mount sensor that is capable of monitoring the movement of a person within a radius of 360<sup>or</sup> and at an angle of approximately 450 relative to the mounting position. The sensor uses PIR (Passive InfraRed) technology to detect real movement of a body that emits certain infrared radiation and that moves from a certain speed. The sensor sends the information on whether there is a presence in the room and the ambient temperature, wirelessly to the energy control unit from time to time, and the control unit is in charge of processing this information.
If a person is in the room and has been identified in the control unit, but a programmable time X has passed without any movement in the room being detected, the control unit disconnects the elements with the highest electrical energy consumption.
If a person is not in the room (not identified in the control unit), there is the option of programming a comfort temperature so that the room remains at a certain temperature. The control unit processes the temperature information received from the sensor and acts accordingly by activating or deactivating the 30 heating or air conditioning elements.
On the other hand, the motion sensor and thermostat 1 is powered by 5 alkaline batteries and has a current draw of tens of microamps which allows it to operate autonomously without wiring over several years without the need to change the batteries. On the other hand, it has a wireless communication module 35 3 that allows it to send and receive information from the control unit without the need to carry out any type of wiring.
It is wireless communication according to the IEEE802.15.4 2.4 Ghz standard. As sensor elements it has a PIR 4 sensor (Passive InfraRed) with built-in optics that allows controlling the movement of a person and a digital thermostat 2 with a resolution of + -I.50C that measures the ambient temperature. Lastly, it has a configuration button 6 that allows the sensor to be synchronized with the control unit during system start-up so that each sensor is paired with its control unit.
The door / window sensor 15 is an element that is mounted on the frame of a window or a door and which is capable of detecting the open or closed position of the same by means of magnetism. The sensor uses a magnet 18 attached to the movable part of the door / window and a vacuum reed bulb 16 (or reed switch) on the window / door frame 45, to detect the correct alignment between the two pieces that connect it. make up (15, 18). The door / window sensor 15 can also be of other technologies, such as a reflective sensor that emits a modulated infrared light signal that is reflected off the door frame and bounced back to the sensor. In the event that the door is opened, the signal could not bounce off the frame and therefore the sensor would not detect it, indicating that the door or window is open.
When mounting the door / window sensor 15 the two pieces must be perfectly aligned when the door or window is closed. The moment the door / window is opened the two pieces are misaligned and the sensor detects the opening. At that moment the sensor sends the information that a door or window has been opened, wirelessly to the energy control unit, and the control unit is in charge of processing this information and deactivating the air conditioning, heating or the service that is scheduled.
The door / window sensor 15 is powered by alkaline batteries 14 and has a current draw of tens of microamps allowing it to operate autonomously without wiring over several years without the need to change batteries. On the other hand, it has a wireless communications module 13 that allows it to send 60 and receive information from the control unit without the need for any type of wiring. It is wireless communication according to the IEEE802.15.4 2.4 Ghz standard. As sensor elements, it has a reed bulb 16 or similar that allows detecting the proximity of a magnetized piece 18. Finally, it has a configuration button 17 that allows the sensor to be synchronized with the control unit during system start-up so that each sensor is paired with its control unit.
Lastly, the room status display 19 is an element that is mounted outside the room and is capable of displaying the status of the room, occupied or unoccupied, on a display element 22. To do this, the room status display 19 communicates wirelessly with the control unit
ES 2 350 996 Al of energy 8 which is what tells you what state the room is in. The state of the room depends on whether the person's identification card 12 is inserted into the power control unit 8 and on the motion information provided by the motion sensor and thermostat 1. The room status display 19 is powered by alkaline batteries 21 and has a current draw of tens of microamps, allowing it to operate autonomously without wiring over several years without the need to change the batteries. On the other hand, it has a wireless communication module 20 that allows it to send and receive information from the control unit without the need for any type of wiring. It is wireless communication according to the IEEE8.2.15.4 2.4 Ghz standard. Various technologies can be used as display element 22: fixed or flashing low consumption LED diode, display, electrochromic element / module, etc.
Finally, it has a configuration button 23 that allows the room status display 19 to be synchronized with the control unit during system start-up, so that it is paired with its control unit.
