[0026] Embodiment 2

[0027] As Figures 1-4 shown, the buzzer 2 is electrically connected to the microprocessor 15, the digital tube 3 is electrically connected to the microprocessor 15, and the number of display digits of the digital tube 3 is customized according to the needs of the user. The digital tube switch 4 is electrically connected to the digital tube 3, and the buzzer switch 5 is electrically connected to the buzzer 2 for convenient control. The first anti-disassembly switch 6 and the second anti-disassembly switch 7 are electrically connected to the DB37 male head 13. The DB37 female head 8 is fixed to the expansion board body 1 by screws. The DB37 male head 13 and the DB37 female head 8 have the same specifications for convenient installation and disassembly. Connection slots are correspondingly installed on the transfer board 9 and the expansion board body 1. The super network port module 10 is circuit-connected to the transfer board 9. A number of detectors 11 are installed at equal distances to increase the detection range.
