Description of the drawings

[0028] The present invention will be further described below with reference to the drawings and embodiments.

[0029] FIG. 1 is a schematic diagram of the intelligent storage device robot of the present invention.

[0030] FIG. 2 is a flowchart of the clothing processing method of the present invention.

Detailed ways

[0031] With reference to FIG. 1, an intelligent hospital bed unit management system of the present invention, an intelligent hospital bed unit management system, includes an alarm button arranged at the head of the hospital bed and a first gravity sensor arranged in the locker of the hospital room. The bottom of the bed is also provided with an infrared sensing device, and all the beds in the ward are sequentially numbered and entered into the central computer database;

[0032] Through the alarm button, new patients can call the robot for bed unit processing at any time or perform the corresponding bed unit processing when the discharged patient leaves, and use the first weight sensor and the infrared sensor device to double detection to ensure that the patient leaves automatically Calling the robot to process the hospital bed unit is simple, convenient and efficient.

[0033] It also includes an intelligent storage device robot, the body of the intelligent storage device robot is a storage box structure 1, the bottom of the storage box structure 1 is provided with a second gravity sensor 2, and the edge of the storage box structure 1 One side is provided with a mechanical arm 3, the other side is provided with a disinfecting water spray device 4, and a crawler 5 is connected through a transmission device below. The crawler is equipped with a brake device.

The bottom of the track is also provided with a dust collector, and the intelligent storage device robot is also provided with a storage module, a control module, a wireless module, and a radar module;

[0034] The alarm button, the first gravity sensor, the infrared sensing device and the wireless module are all communicatively connected with the central computer.

[0035] The wireless module of this embodiment adopts the GPRS module, which has relatively low connection costs and high resource utilization. In the GSM network, GPRS first introduced the packet switching transmission mode, making the original circuit switching mode GSM transmission data fundamental Sexual changes are particularly important when wireless resources are scarce. According to the circuit-switched mode, during the entire connection period, the user will occupy the wireless channel alone regardless of whether it transmits data. During the conversation, many applications often have a lot of free time, such as Internet browsing, sending and receiving E-mail, and so on. For the packet switching mode, users occupy resources only during the period of sending or receiving data, which means that multiple users can share the same wireless channel efficiently, thereby improving resource utilization. The billing of GPRS users is mainly based on the amount of communication data, which embodies the principle of "how much you get, how much you pay". In fact, the connection time of GPRS users may be as long as several hours, but they only need to pay relatively low connection fees.

[0036] GPRS can provide a transmission rate of up to 115 kbps (the highest value is 171.2 kbps, excluding FEC). This means that within a few years, GPRS users can browse the Internet as fast as ISDN users through portable computers, and it also makes possible some mobile multimedia applications that are sensitive to transmission rates.

[0037] Short access time The packet switching access time is shortened to less than 1. GPRS is a new GSM data service, which can provide mobile users with wireless packet data access services.

[0038] The brake device of this embodiment adopts brake pads, and the brake pads are used, which has a simple structure and high efficiency.

[0039] The radar module of this embodiment uses a laser positioning device, and uses aTINY small dot laser positioner. The laser positioning device includes a laser emitting device arranged at the front end of the smart storage device robot and a laser emitting device arranged around the laser emitting device. Group of laser receivers.

[0040] When working, the laser is emitted through the rotating mirror mechanism. When the cooperative road sign formed by the retroreflector is scanned, the reflected light is processed by the photoelectric receiving device as a detection signal, and the data acquisition program is started to read the code of the rotating mechanism. The disk data (the measured angle value of the target) is then transmitted to the host computer through communication for data processing. According to the position of the known road sign and the detected information, the current position and direction of the sensor in the road sign coordinate system can be calculated, thereby To achieve the purpose of further navigation and positioning.

[0041] Laser ranging has the advantages of narrow beam, good parallelism, small scattering, and high resolution in the ranging direction.

[0042] The modulated signal is emitted by the infrared light-emitting tube, and the infrared photosensitive tube receives the infrared modulated signal reflected by the target, and the elimination of ambient infrared light interference is ensured by the signal modulation and the special infrared filter. Set the output signal V. Represents the voltage output of the reflected light intensity, and Vo is a function of the distance between the probe and the workpiece:

[0043] Vo = f (x, p) where ρ is the reflection coefficient of the workpiece. ρ is related to the color and roughness of the target surface. X is the distance between the probe and the workpiece. When the workpiece is the same target with the same P value, X and Vo correspond one-to-one. X can be obtained by interpolating the experimental data of the proximity measurement of various targets. In this way, the position of the robot from the target object can be measured by the infrared sensor, and then the mobile robot can be navigated and positioned by other information processing methods.

[0044] Although infrared sensor positioning also has the advantages of high sensitivity, simple structure, low cost, etc., because of their high angular resolution and low distance resolution, they are often used as proximity sensors in mobile robots to detect proximity or Sudden movement obstacles facilitate the emergency stop of the robot.

[0045] The storage module stores a fixed path corresponding to the hospital bed number, and uses the ROS robot system to enter the robot

Set the travel path and set the navigation target point, that is, each bed. And store the movement code of the robot arm, the code of automatically starting the vacuum cleaner and the code of automatic spraying disinfectant water in the storage module, which are executed by the control module.

[0046] Set the first gravity sensor empty weight to indicate Mkg, Beifan +0.1kg is the first weight threshold Ml, set the second gravity sensor empty weight to indicate Nkg, Beixin +O. lkg is the second weight threshold N1

[0049] S11. When the patient is discharged from the hospital, press the bedside alarm button, and at this time it is determined that there is a management requirement for the bed unit;

[0050] S12. If the patient forgets to press the button, set if the one-hour locker's first gravity sensor indicator is lower than the first weight threshold M1 and the bed infrared sensor device displays no human infrared information, it is determined that there is bed unit management Requirement, place the infrared sensing device in the center of the lower part of the hospital bed, and set the sensing distance to 2.5 meters to ensure that the patient unit is covered;

[0051] S2. The central computer sends a selection instruction to the robot through the wireless module, and randomly selects one of the robots marked as available to rush to the patient bed corresponding to the management needs of the bed unit according to the set path;

[0052] S3. When the robot moves, the laser emitting device emits laser light and is received by the ultrasonic receiving device after reflection, and then the robot control device calculates the propagation distance S according to the laser positioning device, and when the calculated distance S is higher than the dangerous distance threshold , Where the dangerous distance threshold can be set artificially within the range of 0.5 to 3 meters. In this embodiment, it is 1.5 meters. Then the control module sends out a braking command. After the braking device receives the braking command, the braking device brakes;

[0053] S4. After the robot arrives at the designated bed, the control module issues an instruction to the dust collector to remove dust, to squeeze the disinfectant spray device for disinfection, and then to perform a standard clothing change operation;
