The intelligent switch connecting pin monitoring method of claim 5, wherein when the acceleration sensor triggers the system to operate and the vibration generator does not generate electricity, it is determined that the whole system is started due to acceleration change caused by the operation of the switch machine, and the monitoring data reflects the change of the switch resistance in the states of starting, working and ending the operation of the switch machine.
10. The intelligent switch connecting pin monitoring method as claimed in claim 5, wherein when the vibration generator trigger system is operated and the vibration generator generates electricity normally for a time longer than 10s, the power generation gradually decreases the acceleration sensor value to approach the initial state, and the train passing is determined, and during the process, the switch locking state switching resistance condition is monitored when the train passes through the switch.
11. The intelligent monitoring method for switch connecting pins according to claim 5, wherein the connecting pins collect the switching force to reflect the switch switching resistance, and the upper computer analyzes the switch switching resistance corresponding to the switch switching action process to obtain the switch health status.
