Through the above it is known that the scheme based on the embodiment of the present invention, in the remote control command that main website issues, simultaneously
It issues information object address (corresponding to remote controlled point) and remotely-controlled object coding will be first with remote controlled point after end of standing receives remote control command
Number corresponding remotely-controlled equipment is searched, whether the number that the equipment is rechecked after finding is consistent with the number issued.If double
Side's number is consistent, then executes the remote control command issued, otherwise, cancel the execution of remote control command.This prevents what is be accidentally remotely controlled
Occur, after there is following two situation, the result for being remotely controlled execution, which will avoid, to be accidentally remotely controlled.
One, main website should be No. 1 point by the associated remote controlled point mistake of remotely-controlled object, such as corresponding remote controlled point of certain equipment, but
Since the remote controlled point of the equipment is accidentally set as No. 2 points in main website by automation personnel, when sending out remote control command to the equipment,
Remotely-controlled object coding is increased in the order issued, after end of standing receives remote control command, can first find the corresponding equipment of No. 2 points, then
Whether with the coding that issues consistent, find since the remotely-controlled object issued encodes corresponding equipment with end of standing if checking the device coding
Equipment be not the same equipment, and the coding of equipment has uniqueness, and therefore, coding is certainly inconsistent, and remote control command will be by
It cancels.
Secondly, main website it is correct by the associated remote controlled point of remotely-controlled object, but dislocation or mixed occurs for the remote controlled point table sequence at end of standing
Disorderly, such case is likely to occur when being forwarded table maintenance to station end telecontrol device, once this occurs, end of standing
Remote controlled point and the corresponding relationship of remotely-controlled equipment will malfunction, it is selected according to remote control point number when main website issues remote control command
After remotely-controlled equipment, then carry out device coding comparison, just will appear coding it is inconsistent as a result, same, remote control command will be taken
Disappear execution.
