The data part contains the serial number of the card and the body temperature information. Each data acquisition terminal has a terminal number, and the terminal number can indicate which data acquisition terminal uploads the data packet. The batch number C is used for identifying the number of the data packet, and when two continuous card swiping record packets from the same data acquisition terminal are received, if the batch number is discontinuous, the packet loss can be judged to occur. The batch numbers are counted from 170 to 250. When the count reaches 250, then the process returns to 170. The last card swipe record has 0X0B as an end character.
When the wireless data acquisition terminal receives a token packet sent by the base station, the data acquisition terminal packs data into a data frame and sends the data frame to the data base station, and the data frame is formed by adding three special bytes behind the data packet and respectively represents a batch number, a counting bit and an end symbol.
As shown in fig. 9, the operation process of the epidemic prevention system based on the temperature sensor RFID is as follows: the personnel wear the body temperature bracelet with the RFID temperature measurement chip and carry out remote contactless interaction with the RFID card reader to upload own basic information, body temperature and action track. After electrifying, the single chip microcomputer CPU1 (namely the single chip microcomputer U3) carries out system initialization, then the CPU1 carries out data acquisition of the RFID card reader, epidemic prevention data are uploaded to the base station through the serial port communication module, then the base station sends the data to the cloud server for subsequent processing, and the end user can check the information of the card swiping personnel and the body temperature condition through a computer browser or a mobile phone APP so as to know the physical health condition of the personnel. If the person with abnormal body temperature is found, the detection of whether the person is infected with epidemic situation can be further carried out.
The data terminal adopts the Intel atom series as a main control chip, uses a Windows Server 2012 system, an external antenna and a network, and is used for collecting information uploaded by equipment, integrating personnel information and connecting a cloud.
As shown in fig. 10 and 11, in the case of a network, a supervisor can log in the monitoring platform at any place to check the health condition of a person. Meanwhile, the platform has an automatic alarm function, and can timely inform the supervision personnel when the body temperature of the personnel is abnormal.
As shown in fig. 12, the supervisor can check the action track of any person through the platform, and after finding out a person with abnormal body temperature, the supervisor can find out the person with abnormal body temperature through the action track and simultaneously check the person who has contacted with the person.
The method adopted by the second scheme is completely the same as the software background data processing part, the difference lies in that the transmission process of the data is different from that of the first scheme, the transmission process adopted by the second scheme is lora communication, the data collected by the terminal is transmitted to the lora gateway through lora, and then the data is transmitted to the background schematic diagram from the lora gateway through a 4g network, as shown in fig. 13.
As shown in fig. 14(a) and 14(b), the lora terminal is connected to the R2000 card reader according to the schematic diagram, the PA2 and PA3 pins of the lora terminal are connected to the 6 th and 7 th pins of the R2000, the PB6, PB5, PB4, PA10 and PA9 pins of the lora terminal are sequentially connected to the 5 th, 6 th, 7 th, 8 th, 9 th and 10 th pins of the lora terminal, the rest pins of the lora terminal are floating, the 10 th pin of the lora terminal is connected to VCC, the 11 th pin is connected to GND, the 1 st and 14 th, 8 th and 10 th pins of the R2000 high-frequency reader are connected to GND, the 2 nd and 13 th pins are connected to the power supply, and the 12 th pin is connected to the resistance pull-up power supply.
The data collected by the terminal can be transmitted to the lora gateway through the lora local area network, the lora gateway processes the data collected by the terminal and transmits the data to the background through the 4G network, and the 4G module is shown in fig. 15.
The above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and variations, modifications, additions and substitutions which may be made by those skilled in the art within the spirit of the present invention are within the scope of the present invention.
