Amount, battery inspection unit export measurement result to the main monitoring of wall hanging, the main monitoring of wall hanging judge the measurement result whether
Within the scope of scheduled voltage threshold, if being not processed；If not existing, alert；
Whether switching value unit, the switch for measuring wall current trip, the switch input terminal of the switching value unit
One alarm auxiliary contact is installed, when tripping, alarm auxiliary contact movement, the main monitoring collection of wall hanging is alarmed auxiliary contact
Action signal obtains switch trip information；
Insulating unit is measured respectively for the leakage current sensor by being mounted on the multichannel ground path of wall current
Whether leak electricity on the ground line of road.
Further, the main monitoring of the wall hanging is single-chip microcontroller.
Further, the battery inspection unit is light coupling relay, both end voltage of the light coupling relay battery
The AD input terminal for passing to single-chip microcontroller in proportion, is obtained by calculation the cell voltage of every section.
