The utility model relates to a detection circuit adopted by a gateway anti-disassembly device, which comprises a
microprocessor, a three-axis sensor, a distance
transmitter, a communication module and a data
bus, and is characterized in that the three-axis sensor, the distance
transmitter and the communication module are respectively in
bidirectional communication connection with the
microprocessor, and the
microprocessor is in communication connection with an external
server through the data
bus. The distance
transmitter is preferably a
ray distance sensor. The communication module is preferably a 4G communication module, or a 5G communication module, or a 4G / 5G shared communication module. And the three-axis sensor, the distance transmitter and the communication module are respectively in two-way communication connection with the microprocessor through wires. The output end of the microprocessor is connected with the input end of the data
bus, and the output end of the data bus is connected to an external
server On the basis of an original product, the three-axis sensor is additionally arranged, and therefore gateway angle detection is achieved. The installation state of the gateway is detected in real time through a three-axis sensor, when any
direction angle of the gateway is larger than 4 degrees, it is judged that dismounting occurs, and an alarm mechanism is triggered at the moment.
