Control message is sent to device parameter collection writing module by interface.
6th step, device parameter gathers writing module according to write parameters list, to the dry contact of acquisition gateway
DO1 or DO2 enter disconnection and the closure that row write closed and disconnected carrys out controlling switch；Because of hardware coil 1 and line
Circle 2 is powered for a long time can burn damage, so wanting control coil energization period, be write in the dry node of acquisition gateway
It should at the appointed time be sent after closure and write opening operation, time flexibly configurable will to adapt to distinct device
Ask.
The present embodiment is based on above-mentioned power distribution control circuit, both can be flexibly using manually or automatically by gateway
Closure after disconnection and equipment fault that remote control trouble controller switching equipment is powered.Meanwhile, the scheme of the present embodiment is only
Need on the basis of original distributing monitoring system, increase simple relay and magnet coil, interface passes through
Software interface carries out matching somebody with somebody electrical remote control；In addition, operation maintenance personnel can control be matched somebody with somebody manually according to actual conditions selection
Electric system, can also be according to specialty analysis, the distribution key parameter of the equipment collected by gateway and alarm
Information is judged, increases default control rule to realize automatic remote control, rule judgment condition can be according to reality
Border situation is flexibly changed.
Embodiment 3
The scheme that the present invention is provided is further elaborated for the present embodiment main control flow from gateway：
In the present embodiment, voluntarily judge to carry out triggering manually according to operation maintenance personnel to disconnect and closed procedure；Simultaneously
Can be according to device parameter customization control rule, if (fault coverage can be with fault coverage for device parameter
Determined by predetermined threshold value), that is, trigger opening operation；If device parameter returns to normal range (NR),
Trigger closed procedure.
As shown in figure 3, control disconnection process comprises the following steps：
1), breaker is in closure state under initial situation；
2), if control disconnects manually, jump to 4)；
3), disconnected if not manual control, continuation is judged based on rule is automatically controlled, if equipment
It is not in fault coverage, flow terminates；If equipment is in fault coverage, triggering automatically controls disconnection
Request, continues flow；
4), device parameter collection writing module is assisted according to closure state request is write by MODBUS TCP
View writes closure to acquisition gateway dry contact DO1, if write-in is unsuccessful, returns to mistake；Write successfully after
Afterflow journey；
5), now coil 1 is powered, under physical action, and switch can be set to open position；
6) and then in predetermined time interval, device parameter collection writing module is dry to acquisition gateway again
Contact DO1 writes disconnection, if write-in failure, returns to mistake, if write successfully, coil 1 is powered off,
Whole flow process terminates.
As shown in figure 4, control closure flow comprises the following steps：1), initial breaker is off；
2), if control is closed manually, jump to 4)；
3), disconnect, continue based on rule judgment is automatically controlled, if equipment is in if not manual control
Fault coverage, flow terminates；If equipment is not in fault coverage, triggering automatically controls close request,
Continue flow；
4) device parameter collection writing module is assisted according to closure state request is write by MODBUS TCP
View writes closure to acquisition gateway dry contact DO2, if write-in is unsuccessful, returns to mistake；Write successfully after
Afterflow journey；
5) now coil 2 is powered, under physical action, and switch can be set to closing position；
6) and then in predetermined time interval, device parameter gathers writing module again to " acquisition gateway
Dry contact DO2 writes disconnection, if write-in failure, returns to mistake, writes successfully, then coil 2 is powered off,
Whole flow process terminates.
