Start voltage sensor 11 in module 1 and sense the change in voltage of power circuit, the simulating signal collected is converted to digital signal through an A/D change-over circuit 12, pass to the first single-chip microcomputer 13, first single-chip microcomputer 13 passes to signal generator 14 signal, signal receiver 23 in power module 2 receives the signal that signal generator 14 transmits, trigger relay 22 closes, thus solar cell 21 connected by pulley drive motor 53, start working, pulley drive motor is with travelling block 511 action through pulley drive structure 51, inspection device starts to travel, because the orientation of leading line is determined, inspection device can run on fixed-direction, the second pressure transducer 31 simultaneously on induction module 3 starts effect, the simulating signal that second pressure transducer 31 collects is converted to digital signal through the 2nd A/D change-over circuit 32, pass to second singlechip 33, when there is broken string in inspection device place zero line, the bottom of inspection device loses support, the total weight of inspection device will be born by leading line, second pressure transducer collects the sudden change of signal, the digital signal that second singlechip 33 automatic analysis transmits through the 2nd A/D change-over circuit 32, and system zero-line failure signal is passed to regulation and control center through wireless communication module 6, when inspection device normally runs, non-contact infrared temperature sensor 41 in infrared induction module 4 gathers the ruuning situation of power circuit, when the signal open-phase operation that non-contact infrared temperature sensor 41 collects (phase or two-phase broken string), 3rd single-chip microcomputer 43 Driving Stepping Motor 45 carrys out the angle of reconditioner mechanical arm 46, non-contact infrared temperature sensor 41 continues collection signal, in angle (0 degree to the 90 degree) scope that mechanical arm 46 is adjustable, if the signal that non-contact infrared temperature sensor 41 collects still open-phase operation (phase or two-phase broken string), 3rd single-chip microcomputer 43 passes to regulation and control center corresponding abnormal signal through wireless communication module 6, power circuit end between two shaft towers arranges inspection device and stops base, stop base installs the first pressure transducer, when inspection device enters stop base, first pressure transducer 15 detects the pressure of inspection device to it, signal is passed to the first single-chip microcomputer 13, first single-chip microcomputer sends inspection device signal out of service by signal generator, signal receiver receives signal, trigger relay disconnects, inspection device is out of service.
Wireless communication module 6 in the present invention adopts wireless telecommunications system, and the signal that wireless telecommunications system collects according to inspection device is transferred to regulation and control center the practical operation situation of power circuit.
Finally illustrate, above embodiment its describe comparatively concrete and in detail, but only in order to technical scheme of the present invention and unrestricted to be described.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can make suitable distortion and improvement, these all belong to the protection domain of the claims in the present invention.
The present invention does not address part and is applicable to prior art.
