At least part power equipment or transmission line of electricity in the outer bigger region 104 in area 101 are isolated, then whole by fault diagnosis step by step
The regional extent that mode reduces this region 104 is determined, to prevent other loads outside region 104 to be interfered or damage；Another
Register list in individual prominent aspect, adapter device 22 can be periodically updated according to clock setting, in the event of (example
As) fault zone 101, then the registration table of corresponding device in register list is changed, and remove corresponding secondary communications adapter 22,
So, on-line monitoring system of the present invention can immediate updating and sorting power line data, and new electric power can be adapted to automatically set
Standby is incorporated to, so as to reduce data amount of calculation.
In another embodiment, the control logic of above-mentioned setting can also be defined as：Set a preset station region
101, simultaneous selection one is optimal or most stable of with web area, presets region with this to select the group of other regions
Into.For example, the mode of selection is according to the immediate mode in geographical position, or, in the case of there are some failures, switch
231 fail in the case of disconnecting in time, find adjacent adapter 22 to expand by the secondary communications adapter 22 in region 101
This big error protection region.Similarly, the register list of correspondence expanding table region is formd in adapter 22.
