[0023] like Figures 1 to 7 As shown, the utility model includes an RFID (Radio Frequency Identification) electronic tag, an anti-missing terminal and a server, wherein the anti-missing terminal is respectively connected to the RFID electronic tag and the server in communication; the anti-missing terminal includes an MCU (Microcontroller Unit) processing module, a power module, an alarm module, a transmission module and a key module, wherein the MCU processing module is used to collect RFID electronic tag information and send the RFID electronic tag information to the transmission module, wherein the transmission module sends the received RFID electronic tag information to the server, wherein the server processes the RFID electronic tag information based on preset parameters and sends the processing result to the MCU processing module through the transmission module, wherein the MCU processing module determines whether to trigger the alarm module to alarm based on the processing result, wherein the power module is respectively electrically connected to the MCU processing module, the alarm module and the transmission module, and wherein the key module is respectively electrically connected to the alarm module and the MCU processing module.

[0024] The MCU processing module of the anti-missing terminal integrates 2.4GHZ RFID technology. The MCU processing module collects the RFID electronic tag information of the construction site in real time through the 2.4GHZRFID technology. The effective coverage radius of the 2.4GHZ RFID technology is 10m, that is, the MCU processing module using the 2.4GHZ RFID technology collects the RFID electronic tag information within a radius of 10m. If the distance between the RFID electronic tag and the MCU processing module exceeds 10m, the MCU processing module will fail to collect the RFID electronic tag information. The alarm module uses an alarm circuit including LED lights and motor vibrations to alarm. The model of the MCU processing module is NRF51822. The MCU processing module communicates with the transmission module through the serial port. The MCU processing module connects and communicates with the power module, alarm module, and key module through GPIO (General Purpose Input / Output); specifically, Figure 2 , Figure 3 As shown, the MCU processing module is connected to the power module through the P0.17 and P0.18 pins. The P0.17 pin is used as a battery power detection pin, and the P0.18 pin is used to enable the 4G power output. Figure 3 , Figure 7 As shown, the MCU processing module is connected to the key module through the P0.03 and P0.04 pins to realize key recognition; Figure 3 , Figure 5 As shown, the MCU processing module is connected to the motor vibration circuit of the alarm module through the P0.10 pin to realize the driving of the motor vibration; Figure 3 , Figure 4 As shown, the MCU processing module is connected to the light alarm circuit of the alarm module through the P0.0, P0.1, and P0.2 pins to drive the LED of the alarm module to give a light alarm prompt; Figure 3 , Figure 6 As shown, the MCU processing module is connected to the 91st and 92nd pins of the 4G module through the P0.08 and P0.09 pins to realize UART serial communication; the server is a computer.

[0025] The MCU processing module collects multiple RFID electronic tag information bound to the MCU processing module in real time and simultaneously, and sends the collected multiple RFID electronic tag information to the server through the transmission module. The server processes the received multiple RFID electronic tag information according to preset parameters and outputs the processing results. If the number of multiple RFID electronic tag information is consistent with the number of RFID electronic tags bound to the current MCU processing module, and the multiple RFID electronic tag information received by the server matches the RFID electronic tag information bound to the MCU processing module, the server determines that the tool is not missed, and the server continues to receive and process the multiple RFID electronic tag information transmitted by the transmission module; if the number of multiple RFID electronic tag information received by the server is consistent with the number of RFID electronic tags bound to the MCU processing module, the server performs RFID electronic tag matching processing. If at least one RFID electronic tag information among the multiple RFID electronic tags bound to the MCU processing module is matched in the multiple RFID electronic tags received by the server If matching RFID electronic tag information cannot be found in D electronic tag information, the MCU processing module collects the RFID electronic tag information abnormally, and the server determines that the tool is omitted; if the number of multiple RFID electronic tag information received by the server is inconsistent with the number of RFID electronic tags bound to the MCU processing module, the server performs RFID electronic tag matching processing. If at least one RFID electronic tag information among the multiple RFID electronic tags bound to the MCU processing module cannot find matching RFID electronic tag information in the multiple RFID electronic tag information received by the server, the RFID electronic tag information collected by the MCU processing module is abnormal, and the server determines that the tool is omitted; after the server determines that the tool is omitted, it determines when to send an alarm message and whether to send an alarm message based on preset parameters. If the server sends an alarm message to the MCU processing module through the transmission module, it means that the multiple RFID electronic tag information received by the server is continuously abnormal; if the server does not send an alarm message, it means that the server has not continuously received abnormal data. After the MCU processing module receives the alarm information, it triggers the alarm module to sound an alarm, reminding the staff that the tool is missing. After receiving the alarm information, the staff can turn off the alarm through the button module. At the same time, the server starts timing based on the preset parameters after sending the alarm information. If the server still receives abnormal information after exceeding the preset parameters, the server will send the alarm information to the MCU processing module through the transmission module again. The MCU processing module continues to trigger the alarm module to sound an alarm, reminding the staff to find the missing tool until the multiple RFID electronic tag information received by the server matches the multiple RFID electronic tag information bound to the MCU processing module, and then the alarm stops.

[0026] The button module includes a first button and a second button. The first button is electrically connected to the alarm module to control the alarm module to pause the alarm. The second button is electrically connected to the MCU processing module to start or shut down the MCU processing module.

[0027] After receiving the alarm, the staff can pause the alarm and look for tools by pressing the first button. When the staff is preparing for work, they can start the anti-missing terminal by pressing the second button, that is, start the MCU processing module. After the work is finished, the staff can close the anti-missing terminal by pressing the second button to extend the service life of the anti-missing terminal.

[0028] The RFID electronic tag is configured to be in a card shape. The RFID electronic tag is installed on the outside of a tool at a construction site and a rainproof and moisture-proof film is provided on the outside of the RFID electronic tag. Unique ID information is written inside the RFID electronic tag.

[0029] The RFID electronic tag uses an active + passive composite electronic tag. The unique ID of the tag is written inside the RFID electronic tag, and the relevant information of the tool, such as the tool name, size, owner, and purpose, can also be written. If the tool is scrapped and not used, the RFID electronic tag installed on the tool can be removed, and the new tool-related information can be rewritten into the RFID electronic tag, and the RFID electronic tag can be installed on the outside of the new tool. The RFID electronic tag is re-bound to the MCU processing module, and the original RFID electronic tag is unbound from the MCU processing module to avoid abnormalities when the server processes data.

[0030] The preset parameters include an alarm interval parameter, a receiving delay parameter and multiple RFID electronic tag IDs. The multiple RFID electronic tag IDs are all bound to the same MCU processing module. The receiving delay parameter is used to limit the delay time for the server to receive RFID electronic tag information. The server sends secondary alarm information to the MCU processing module through the transmission module based on the alarm interval parameter.

[0031] The alarm interval parameters can be set through the server, and the alarm interval parameters can be set to 3 minutes, 5 minutes, or other durations. After the alarm interval parameters are set through the server, the server will make a secondary alarm based on the set alarm interval parameters, that is, after the server sends the first alarm information, if the server continues to receive abnormal information within 3 minutes, the server will send a second alarm information.

[0032] The receiving delay parameter can be set through the server, and the receiving delay parameter can be set to 20 seconds, 30 seconds, or other durations. After setting the new receiving delay parameter, the server will determine the information abnormality based on the new receiving delay parameter. If at least one of the multiple RFID electronic tags bound to the MCU processing module stored in the server cannot find matching RFID electronic tag information in the multiple RFID electronic tag information received by the server, the server continues to receive the RFID electronic tag information and counts. After 20 seconds, if there is still at least one of the multiple RFID electronic tags bound to the MCU processing module stored in the server that cannot find matching RFID electronic tag information in the multiple RFID electronic tag information received by the server, the server sends an alarm message, otherwise, the server continues to receive RFID electronic tag information.

[0033] The transmission module is a 4G wireless communication module.

[0034] The MCU processing module communicates with the server through the 4G wireless communication module. The transmission module uses a wireless communication module of model SLM328, and the transmission module communicates with the MCU processing module through the UART (Universal Asynchronous Receiver Transmitter) serial port. Figure 3 , Figure 6 As shown, the P0.08 and P0.09 pins of the MCU processing module are connected to the 91 and 92 pins of the 4G wireless communication module to realize UART serial port communication, thereby realizing data transmission between the MCU processing module and the server.

[0035] The power module is a lithium battery.

[0036] The power module continuously supplies power to the MCU processing module, the alarm module and the transmission module. The power module adopts the charging chip model SGM41524. When the power module is low on power, it can be charged by a 5V output charger. Setting the power module as a rechargeable battery can extend the battery life and reduce the pollution caused by the battery to the environment.

[0037] When in use, an RFID electronic tag is installed on each tool in the staff's toolbox. Each staff member is equipped with an anti-omission terminal. The staff member's anti-omission terminal is used to bind the RFID electronic tags on multiple tools in the toolbox, and the binding information is stored in the server to ensure that the server can determine whether the workpiece is missing based on the binding information. The MCU processing module of the anti-omission terminal continuously collects RFID electronic tag information on the tool, and sends the collected RFID electronic tag information to the server through the transmission module. The server processes the received RFID electronic tag information based on the stored binding information of the anti-omission terminal. If the multiple RFID electronic tag information bound to the anti-omission terminal stored on the server corresponds one-to-one with the multiple RFID electronic tag information received, the server determines that the tool is not missing. If at least one RFID electronic tag information among the multiple RFID electronic tags bound to the anti-omission terminal stored on the server cannot find a matching RFID electronic tag information in the multiple RFID electronic tag information received by the server, the server determines that the tool is missing and continues to receive. RFID electronic tag information, if the server determines that the tool has been missing for a period of time exceeding the receiving delay parameter, and the server continues to receive abnormal information, the server sends an alarm message, and the MCU processing module receives the alarm message through the transmission module, triggering the alarm module to alarm. After the staff receives the alarm, they retrieve the tool in time and the alarm stops. If the staff pauses the alarm by pressing the first button, the server continues to receive the RFID electronic tag information. If the server sends the alarm for a period of time exceeding the alarm interval parameter, and the server continues to receive abnormal information, the server sends the alarm message again until the multiple RFID electronic tag information collected by the MCU processing module received by the server corresponds to the multiple RFID electronic tag information bound to the MCU processing module. By setting the RFID electronic tag on the tool and binding the anti-missing terminal to the RFID electronic tag on the tool, when the distance between the tool and the anti-missing terminal exceeds the coverage range of the anti-missing terminal, the anti-missing terminal will alarm and remind the staff that the tool is missing, which can prevent the missing of the tool from causing a traffic safety accident at the construction site, and can also improve the maintenance efficiency of the staff.

[0038] The above is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention. Any simple modification, change and equivalent structural transformation made to the above embodiments according to the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
