Detailed Description
The technical solution of the present invention is further described below with reference to the accompanying drawings, but not limited thereto, and any modification or equivalent replacement of the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention shall be covered by the protection scope of the present invention.

the grounding fixed point detection head is installed on a grounding wire fixed point of the anti-theft equipment, and the fixed installation structure of the grounding fixed point detection head can cause the resistance characteristic change of the grounding fixed point detection head when the grounding wire fixed point is removed. The grounding fixed point detection head is fixed to a building grounding point or other fixed grounding points which are not easy to detach and carry in a physical mode. The fixed-point-of-contact detection head may normally form a loop with specific resistance characteristics, through which the cable measurement signal is detected. The fixed-point grounding detection head is damaged under the condition of being stolen and disassembled, and the specific resistance characteristic of the fixed-point grounding detection head is changed.
The grounding detection cable is used for connecting the grounding fixed point detection head and the detection line characteristic detection circuit. The grounding detection cable is characterized in that the mounting structure of the grounding detection cable meets the requirement that the grounding detection cable is damaged before the grounding fixed point detection head is damaged without being detached, the grounding detection cable is disconnected from the grounding fixed point detection head structure due to damage, and the specific resistance characteristics received by the detection line characteristic detection circuit are changed. The grounding detection cable consists of an internal grounding wire, an internal detection wire and an external insulating sheath, and the insulating sheath can insulate the grounding wire and the detection wire from each other.
The detection line characteristic detection circuit is used for detecting specific resistance characteristics of the grounding detection cable and the grounding fixed point detection head. When the grounding detection cable is not stolen, the grounding fixed point detection head has a good structure, and the detection line characteristic detection circuit can detect the specific resistance characteristic of the grounding fixed point detection head. When the ground fixing point detecting head or the ground detecting cable is broken, specific resistance characteristics of the ground detecting cable and the ground fixing point detecting head are broken. The specific resistance characteristics of the grounding detection cable and the grounding fixed point detection head are converted into voltage signals by the detection line characteristic detection circuit.
The microprocessor module is connected with the detection line characteristic detection circuit. The microprocessor module carries out real-time analysis on the conversion voltage result of the detected line characteristic detection circuit, monitors the specific resistance characteristic of the detected line characteristic detection circuit in real time, and if the specific resistance characteristic is equal to a defined value during installation, the detection structure is complete and does not give an alarm. When the grounding detection cable and the grounding fixed point detection head are damaged, the specific resistance characteristic changes, if the specific resistance characteristic is different from a defined value in installation, the change is detected by the embedded processor module in real time and then is immediately subjected to remote alarm through the network communication module and field alarm through the sound-light alarm module. The microprocessor module is also responsible for information input, processing and output of the network communication module, the sound-light alarm module, the power supply module, the positioning module, the detection line characteristic detection circuit and the data recording module.
The network communication module uses a mobile network for communication, information of the detection line characteristic detection circuit, the positioning module and the power supply module collected by the microprocessor module can be transmitted to the network platform, and network alarm is carried out through the network communication module when the insulating structure is damaged.
The power supply module provides various power supply modes, a built-in battery of the module supplies power to a microprocessor module, a network communication module, a sound and light alarm module, a positioning module, a data recording module and a detection line characteristic detection circuit of the anti-theft alarm device, and the module can be externally connected with devices such as solar energy, wind energy and the like to charge the built-in battery.
The positioning module can detect the position of the machine, and if the microprocessor module detects that the position of the positioning module is changed during alarming, the positioning module immediately reports the position information through the network communication module.
The data recording module can store the information of the microprocessor module, the network communication module, the sound-light alarm module, the power supply module, the positioning module and the detection line characteristic detection circuit which are processed by the processor module.
The shell is responsible for the moisture and water resistance, heat dissipation and cooling and physical impact damage prevention of the microprocessor module, the network communication module, the sound-light alarm module, the power supply module, the positioning module, the detection line characteristic detection circuit and the data recording module.
The working principle is as follows:
the fixed mounting structure of the grounding fixed point detection head meets the requirement that the resistance characteristic of the grounding fixed point detection head is changed when the grounding fixed point is removed. The grounding detection cable is connected with the grounding fixed point detection head and the detection line characteristic detection circuit, and equipment can be taken away only by damaging the grounding detection cable when the grounding fixed point detection head is not detached. When the grounding detection cable is not stolen, the grounding fixed point detection head has a good structure, and the detection line characteristic detection circuit can detect the specific resistance characteristic of the grounding fixed point detection head. When the ground fixing point detecting head or the ground detecting cable is broken, specific resistance characteristics of the ground detecting cable and the ground fixing point detecting head are broken. The microprocessor module carries out real-time monitoring and analysis on the conversion voltage result of the detected line characteristic detection circuit, and if the specific resistance characteristic is equal to a defined value during installation, the detection structure is complete and no alarm is given. When the grounding detection cable and the grounding fixed point detection head are damaged, the specific resistance characteristic can be changed immediately, and if the specific resistance characteristic is different from a defined value during installation, the detection structure is incomplete and an alarm is given.
