As shown in fig. 2 and 3, the conditioning mechanism 1 includes: the device comprises an insulation box 10, an input straight pipe 11, a sealing ring 12, an input end circuit board 13, an input end step-down resistor 14, an output end step-down resistor 15, a bidirectional Transient Voltage Suppression (TVS) diode 16, an output end circuit board 17 and an output straight pipe 18. The input end circuit board 13, the input end step-down resistor 14, the output end step-down resistor 15, the bidirectional Transient Voltage Suppression (TVS) diode 16 and the output end circuit board 17 are positioned inside the insulation box 10, and the insulation box 10 can effectively prevent interference caused by external signals in the signal conditioning process. The input straight tube 11 and the output straight tube 18 extend from the inside to the outside of the insulation box 10, and the side wall of the output straight tube 18 is provided with a collection through hole 180. The number of the input straight pipes 11 and the number of the output straight pipes 18 are two, the two input straight pipes 11 are respectively used for receiving the positive electrode and the negative electrode of an input cable, and the two output straight pipes 18 are respectively used for receiving the positive electrode and the negative electrode of an output cable.

The input-side dropping resistor 14, the output-side dropping resistor 15, and the bidirectional Transient Voltage Suppression (TVS) diode 16 are electrically connected to the input-side circuit board 13 and the output-side circuit board 17, respectively.
