Shield, the short circuit of 100 system prompt system somewhere of host computer, host computer 100 can prompt operating personnel to close short circuit overcurrent protection switch,
Operating personnel prompt power turn-on switch according to host computer 100.Have from power turn-on switch to jump electric protection again
The 100ms times.Host computer 100 sends out self-test order using this time, there will be no feedback data after remote control valve 901, because
For behind remote control valve 901 since power supply short circuit does not have power supply.At this moment positive overcurrent protective switch jumps electricity, host computer again
It is power cord 400A points between remote control valve 901 and remote control valve 902 that 100 prompts have been known according to inspection result just now
Short circuit.Calculator can prompt operating personnel to close positive power switch again.
Meanwhile host computer 100 can send an order to the control unit of remote control valve 901, command context is turned off distant
The intermediate relay K2 of valve 901 is controlled, the actuation time of intermediate relay only needs 10mS, such power supply can be normally from just
To remote control valve 901 is flowed to, make remote control valve 901 that can work normally forward；Then calculator can control reversed overcurrent
Protection switch closes, meanwhile, host computer 100 sends one to remote control valve 902 by bus system and cuts off remote control valve 902
The power supply of the order of intermediate relay K1, such reverse flow can be transported to always remote control valve 902.
By operation above, this system can not only judge that 400 short circuit event of power cord occurs in whole system where
Barrier, additionally it is possible to which K1 and K2 by being arranged in control unit separate fault point so that whole system can continue to Emergency use.
