Road current sensor 131 and indication circuit current sensor 132 are respectively used to the current information of monitoring actuating circuit and indicate electricity
The current information on road.
Wherein, actuating circuit current sensor 131 and indication circuit current sensor 132 are for monitoring action connection point and table
Show the current information in contact handoff procedure, which includes the electricity that indication signal and feedback representation signal are acted in actuating circuit
Flow valuve and current signal time difference can calculate and reflect action connection point and indicate the resistance value of contact.
With continued reference to Fig. 3, except the actuating circuit current sensor and table in above-mentioned actuating strut, indication rod and electric circuit
Show outside circuital current sensor, can also carry out status monitoring to the other structures component in goat, wherein further including locking dress
It sets, contact seat and bearing block etc..Fig. 9 is the mounting structure schematic diagram of locking strain gauge provided in an embodiment of the present invention,
With reference to Fig. 3 and Fig. 9, optionally, information acquisition module 11 further includes locking strain gauge 14, and locking strain gauge 14 is arranged
In on the outer wall of the latching slot of goat, locking strain gauge is used to monitor the locking stress information of locking device；Goat
Unit information further include locking device locking stress information.
It wherein, include locking iron 342 and locking block 341 in the locking device of goat, locking iron 342 is fixed with actuating strut
Connection, actuating strut are pulled to during in place, and locking iron 342 is followed mobile and fallen into locking block 341, right by locking block 341
The limit of locking iron 342 is to realize the locking of actuating strut.When locking iron 342 is located in locking block 341, since there may be dynamic
Make bar still situations such as movement or external tongue receive extruding or deformation has occurred in actuating strut, at this time locking iron 342
To 341 extrusion stress of locking block, the i.e. stress of locking device, locking iron 341 can generate deformation, locking stress when being squeezed
Sensor 14 then reflects stress information according to the deformation of locking iron 341.It is passed by the way that locking stress is arranged in 341 two sides of locking block
Sensor 14 can be in the case where actuating strut stretches out and pulls in two kinds of locking states, locking device when monitoring applies different loads to actuating strut
Stress variation.The stress monitoring of locking device can reflect locking force information in real time, thus reflect locking device unlock and
Locking, and can reflect indirectly movement motor actuating strut in place when still when work, crossing vehicle, tongue is squeezed situation
That is switch point housing degree and situations such as external connection rod piece deformed state.
