Further, the grid switching operation monitor in real time anti-error system is also included for storing microcomputer anti-misoperation system generation behaviour Make the data server of ticket, the data server is put error system wireless telecommunications and is connected with microcomputer.
Further, the microcomputer anti-misoperation system is attached with Automatic monitoring systems by network or serial ports;It is described After microcomputer anti-misoperation system receives the equipment reality remote signalling status information of Automatic monitoring systems, equipment state renewal is carried out.
Further, the hand-held mobile terminal is communicated with lockaid gun by bluetooth;When lockaid gun unlocks mistake, Lockaid gun will unlock error message and report in real time to hand-held mobile terminal.
When lockaid gun is operated, it is understood that there may be task unauthorized, unblock error apparatus, operating condition do not meet (such as:Electrically Lock, electrical verification lock etc.) situations such as, for aforesaid operations error message, lockaid gun can be reported to hand-held mobile terminal in real time.
Further, the microcomputer anti-misoperation system passes through wifi or 3G/4G network communications with hand-held mobile terminal;Work as unlocking During device unblock mistake, the hand-held mobile terminal is sent to microcomputer anti-misoperation system in real time by error message is unlocked.
By opening the step such as operation order and mandate, down operation ticket, transfer operation ticket to lockaid gun, in operation, Although there is handheld terminal to scan the operating procedure of Quick Response Code, because there is too many similar interval, causing to be strayed into other intervals may Property it is very big, hand-held mobile terminal by unlock error message be sent to microcomputer anti-misoperation system in real time, microcomputer anti-misoperation system receives mistake Voice and alarm prompt are carried out after false information, reminds administrative staff to process it accordingly, reached to live grid switching operation Monitoring.
The second object of the present invention is to provide a kind of control method of grid switching operation monitor in real time anti-error system, including with Lower step:
Step 1, generation operation order, draw up to meet the behaviour of grid requirements by way of microcomputer anti-misoperation system is based on figure Make ticket, during making out an invoice, the analysis that need to carry out anti-error logical condition judges, after making out an invoice successfully, is preserved to database by examination & verification Server, downloads for hand-held mobile terminal;
Step 2, down operation ticket, operating personnel check that active user has authorized and allowed down by hand-held mobile terminal The operation order of load, the operation order needed for selection is downloaded;
Step 3, transfer operation ticket, the operation ticket data that hand-held mobile terminal will have been downloaded currently are transmitted by bluetooth approach It is standby after lockaid gun reception operation ticket data to lockaid gun;
Step 4, report error message, set for scanning Quick Response Code mistake in operation, unauthorized, unblock mistake The error message that standby, operating condition is not inconsistent, hand-held terminal is reported to microcomputer anti-misoperation system in real time, if operation is correct, no Reported;
Step 5, unblock operation, according to operation order requirement, lockaid gun is inserted corresponding lock set by operating personnel, right Eligible lockset is unlocked operation, if ineligible, lockaid gun should report miscue, and feed back to hand-held mobile whole End, hand-held mobile terminal is automatically fed to microcomputer anti-misoperation system again;
Step 6, back delivery operations, after equipment unblock is operated successfully, record to microcomputer anti-misoperation system passback current operation, and Into next step operation.
