[0029] If the identity information of the operator stored in the RFID controller contains identity information of the operator that is not included in the response signal, the RFID controller sends an alarm message to the background management platform; the background management platform receives the alarm message and issues an alarm.

[0030] In order to further optimize the above technical solution, the RFID controller includes: a main control circuit, which is electrically connected to the communication circuit, the power management circuit, the TYPE-C interface circuit, and the comparison unit;

[0031] The power management circuit is used to provide power supply management from the TYPE-C interface circuit to the main control circuit;

[0032] The communication circuit is used to provide data exchange between the main control circuit and the outside;

[0033] The TYPE-C interface circuit is used to provide 5V power supply and USB data communication connection;

[0034] The comparison unit is used to compare the identity information of the operator in the response signal with the identity information of the operator stored in the RFID controller.

[0035] What needs to be understood is: RFID controller identity information comparison, the identity information stored in the RFID controller is: facial information and identification ID; entering the electronic fence area to collect facial information and input identification ID; the host computer retrieves the operator's identity information stored in the RFID controller for comparison.

[0036] In order to further optimize the above technical solution, the communication circuit includes: an RF signal processing circuit, a radio frequency amplification circuit, a coupling circuit, a receiving circuit, a radio frequency antenna and a Bluetooth module;

[0037] The Bluetooth module is electrically connected to the main control circuit and provides data communication to the terminal;

[0038] A bidirectional signal transmission and reception loop includes the RF signal processing circuit, an electrical connection to the RF amplification circuit, the coupling circuit, the receiving circuit, and the RF signal processing circuit, wherein the RF signal processing circuit is electrically connected to the main control circuit, and the coupling circuit is electrically connected to the RF antenna.

[0039] In order to further optimize the above technical solution, when any infrared grating is blocked, the host or slave that cannot receive the infrared signal will perform an audible and visual alarm prompt operation.

[0040] Specifically, the host sets the signal transmission frequency of the infrared transmitter No. 1 and the signal receiving frequency of the infrared receiver No. 1 in the host according to the mapping table of numbers and transceiver frequencies, wherein the mapping table of numbers and transceiver frequencies is stored in the memory of the master control device of each electronic fence, and the signal transmission frequency corresponding to the number x in the mapping table of numbers and transceiver frequencies is the same as the signal receiving frequency corresponding to the number x+1;

[0041] In order to further optimize the above technical solution, the host or the slave is a cylindrical shell made of a light-transmitting material, a solar panel located on the upper surface of the cylindrical shell, a control button installed on the surface of the cylindrical shell, a base installed at the bottom of the cylindrical shell, and a main controller, an infrared transmitter, an infrared receiver, a chassis, a wireless module, an audio and visual prompt module and a power module located inside the cylindrical shell;

[0045] Specifically, it is convenient to deploy the main machine or cluster machines according to the specific conditions of the open-pit mine.

[0046] Furthermore, the first electronic fence powered on automatically becomes the host to establish a local area network and is assigned the number 1. After the other electronic fences are powered on, they join the local area network and obtain the number n from the host, becoming fence number n. After each electronic fence successfully joins the network, it sets its own signal transmission and reception frequency according to its own number and a mapping table of numbers and transmission and reception frequencies, and activates its own infrared transmitter and infrared receiver. In particular, the infrared receiver No. n of fence No. n and the infrared transmitter No. n-1 of fence No. n-1 are in a transmission and reception relationship with each other, and the infrared receiver No. 1 of the host and the infrared transmitter No. N of fences are powered on in sequence. After the infrared receiver No. n of fence No. n and the infrared transmitter No. n-1 of fence No. n-1 have successfully established a transmission and reception relationship, fence No. n+1 is powered on. After all N electronic fences have successfully established a transmission and reception relationship, a protection area is formed. The protection area is the area enclosed by the infrared gratings between adjacent electronic fences. In specific use, when any infrared grating is blocked, the electronic fence that cannot receive the infrared signal will perform an audible and visual alarm prompt operation. Through the above process, a protective barrier can be effectively established and timely alert external personnel can be provided.

[0047] Furthermore, the RFID controller compares the identity information of the operator in the response signal with the identity information of the operator stored in the RFID controller; if the verification is successful, no alarm will be triggered even if the operator is in an electronic fence.
