B, micro controller module judges whether the vibration of vibrator causes sensor module to generate current impulse, if yes then enter
Step C, otherwise increases the amplification factor of programmable amplifier module, and continues the deterministic process of this step；
C, micro controller module stores self-test information, and the self-test information of storage is broadcasted by radio-frequency module and is issued.
10. working method according to claim 7, which is characterized in that further comprise the given time model in step (6)
Enclose interior DC signal pulse number be more than or equal to given threshold value in the case where and before entering step (7), microcontroller mould
Block measures the pulse width of DC signal within the scope of given time, and judges whether the pulse width is more than or equal to a default threshold
Value, if it is larger than or equal to (7) are then entered step, otherwise continues waiting for the DC signal from signal processing module.
