S3：First electrical signal collection device of shaft tower gathers the electric signal of shaft tower equipment, and electric signal includes time parameter,
The frequency analysis that data processing module calculates the electric signal with time parameter obtains shaft tower harmonic signal；
S4：Electric substation's harmonic signal that shaft tower will be received sequentially is sent into adjacent shaft tower by electric signal R-T unit,
Shaft tower sequentially sends into adjacent shaft tower shaft tower harmonic signal by electric signal R-T unit, when simultaneously shaft tower is subject to two
Stop continuing to send when electric substation's harmonic signal and shaft tower harmonic signal of direction transmission；
S5：The signal sychronisation of shaft tower according to time parameter synchronization electric substation's harmonic signal and shaft tower harmonic signal and transmission extremely
In signal processor, electric substation's harmonic signal and shaft tower harmonic signal are increased shaft tower location parameter by signal processor, at signal
Reason device analysis Traction networks electric signal state, failure simultaneously obtain process signal, and process signal is sent to radio communication emitter
And in battery；
S6：After trigger mechanism on shaft tower receives the trigger signal of locomotive, by the process signal in radio communication transmitter
Send to locomotive, the process signal that will react traction net state on the way by the 3G network communicator of locomotive is sent to intelligent tune
Degree server.
