In step S102, the operation ticket is subjected to error proofing according to a preset rule.
In the embodiment of the present invention, after the operation ticket is generated, the operation ticket is subjected to anti-error check according to a preset rule, where the preset rule may be an anti-error logical expression or an anti-error topology, the operation ticket may be checked in combination with an initial state of an operation object corresponding to the operation ticket when being checked, and the operation ticket may also be checked in combination with other rules when being checked in an anti-error manner, for example, the anti-error check is performed according to trend analysis, and of course, the check may also be performed in a combination of multiple rules, which is not limited herein.
Before the anti-error check is performed on the operation ticket according to the preset rule, preferably, power grid pattern data is obtained from a Geographic Information System (GIS), equipment state data is obtained from a power distribution automation system, and the initialization operation of basic data is completed according to the obtained power grid pattern data and the obtained equipment state data. The device state information may include a device state value and a device state diagram, where the device state diagram refers to a graph corresponding to the device state in the graphical operation interface, and the device state value refers to a state value corresponding to the device state in the database. After the initialization operation is completed, a triggered updating mode is adopted based on real-time remote signaling data of a distribution automation system (DAS system), so that preferably, when a remote signaling data updating notification sent by the distribution automation system is received, equipment state information (updated equipment state information) corresponding to the remote signaling data updating notification is updated to realize real-time updating and displaying of the equipment state.
In step S103, when the operation ticket passes the error checking prevention, the operation ticket is pushed to the power grid management information system for auditing.
In the embodiment of the invention, if the operation ticket passes the error-proof check, the operation ticket is automatically pushed to the power grid management information system for checking or when a pushing request input by a user is received, otherwise, the operation ticket is temporarily stored, and when the operation ticket meets the error-proof check condition, the operation ticket is automatically pushed to the power grid management information system for checking or when the pushing request input by the user is received.
If the operation item is associated with the lock operation, preferably, after the operation ticket is pushed to the power grid management information system for auditing, when a notification that the operation ticket issued by the power grid management information system passes the auditing is received, lock ID sequences corresponding to all operation items associated with the lock operation are acquired from the intelligent lock control system to acquire the operation authority of the lock operation, so that the subsequent operation efficiency of the operation items associated with the lock operation is facilitated.
In step S104, when receiving a notification that the operation ticket audit is passed from the grid management information system, the operation ticket is output.
In the embodiment of the invention, the staff of the power grid management information system can manually check the operation ticket, and when receiving the notice that the operation ticket is checked and passed from the power grid management information system, the operation ticket is output according to the identifier of the guardian and the operator in the operation ticket.
In step S105, the execution of each operation item in the operation ticket is monitored, an execution result after each operation item is executed is obtained, and the device state information is updated according to the execution result.
In the embodiment of the present invention, in the process of monitoring the execution of each operation item in the operation ticket, the following steps may be included:
s1051: and verifying an operator and a guardian who execute the operation order through the power grid artificial intelligence platform.
Specifically, the verification can comprise identity validity verification and dressing compliance verification, when the operator and the guardian are verified, personnel pictures of the operator and the guardian can be obtained, the pictures comprise faces of the guardian or the operator and the dressing, the validity of the identities of the operator or the guardian corresponding to the personnel pictures and the dressing compliance are verified by calling an interface of a power grid artificial intelligence platform, and therefore the verification of the operator and the guardian is achieved by butting with the power grid artificial intelligence platform, and the reliability of the identity validity and the dressing compliance verification is guaranteed.
After the operator and the guardian pass the verification, preferably, when a reading instruction input by the operator is received, the current operation item is automatically read, then the repeating voice of the operator to the current operation item is acquired, and when the text corresponding to the repeating voice is completely consistent with the text corresponding to the current operation item, the operation authority of the current operation item is opened, so that the guardian can remotely monitor a plurality of operation tickets, and the execution efficiency of the operation tickets is improved.
S1052: and when the verification is passed, opening the operation authority of the current operation item in the operation ticket so that the operator executes corresponding operation according to the operation ticket.
Specifically, when the verification passes, the operation ticket is allowed to be executed, the current operation item is confirmed according to the execution sequence of the operation items in the operation ticket, the operation authority of the current operation item is opened, and when the verification fails, the operation ticket is prohibited from being executed. When the operation authority of the current operation item is opened, the operation authority of the operation item before the current operation item is preferably locked to prevent reversible operation, so that the operation ticket is monitored step by step, and the execution safety of the operation ticket is further improved.
S1053: and acquiring an execution result after the current operation item is executed, judging whether the execution result is consistent with the target state in the operation ticket, and if so, jumping to the step S1051 until all the operation items in the operation ticket are executed.
Before obtaining an execution result after executing the current operation item, preferably, identifying the device state after executing the current operation item through the power grid artificial intelligence platform, thereby ensuring accuracy of the operation, specifically, obtaining a device picture after executing the current operation item, calling an interface of the power grid artificial intelligence platform to identify the device state corresponding to the device picture, taking the identification result as an execution result, judging whether the execution result is consistent with a target state in the operation ticket, if so, determining that the current operation item is completely executed, and executing step S1051 until all operation items in the operation ticket are completely executed. And if not, determining that the current operation item is not executed completely. When the execution result is obtained, the equipment state information is synchronously updated according to the execution result, so that the problem that part of equipment states cannot be obtained due to low network distribution automation coverage rate in the prior art is solved, the equipment states are updated, displayed and supervised in real time, the operation object is subjected to real-time error check prevention, the execution safety of the operation ticket is improved, and the operation safety level of the network distribution is improved.
Before the execution result after the current operation item is executed is obtained, preferably, the state of the equipment before the current operation item is executed is identified through the power grid artificial intelligence platform, so that the accuracy of the operation is further ensured. Specifically, an equipment picture before the current operation item is executed is obtained, an interface of a power grid artificial intelligence platform is called to identify an equipment state corresponding to the equipment picture, whether the identified equipment state is consistent with the initial state of the current operation item in the operation ticket or not is judged, if yes, the subsequent operation authority of the current operation item is opened, and if not, the subsequent operation authority of the current operation item is closed, so that the execution safety of the operation ticket is further improved. Of course, the current operation item can be subjected to error-proof check by combining with a five-prevention rule before the current operation item is executed, so that the operation safety is further improved. As an example, the current operation item is an on switch a, the device state before operation in the operation ticket is an on state, before the operation item is executed, a picture of the on switch a is firstly acquired, and if the current state of the on switch a is identified as the on state by calling an interface of the power grid artificial intelligence platform, the operator is allowed to perform the on operation on the on switch a, otherwise, the on operation is not allowed.
In the process of executing the current operation item, preferably, when the operation item related to the lockset operation is executed, the lockset operation instruction is automatically sent to the intelligent lock control system according to the lock ID sequence so as to automatically complete the corresponding lockset operation, so that the effect of one-step authorization is achieved by butting with the intelligent lock control system, and the reliability of misoperation prevention of the distribution network is improved.
Preferably, when the operation order is executed, the operation order is filed to the power grid management information system, so that automatic filing of the operation order is achieved, when the operation order is filed, filing of the filing information corresponding to the operation order is achieved by calling a filing interface of the power grid management information system, and the filing information is stored locally in the web application server, so that a user can check the filing information at any time. The filing information at least comprises complete ticket face information in the operation ticket, and also can comprise a face/dressing compliance verification result corresponding to the operation ticket, whether the operation item is completed, pictures of equipment before and after the operation item is executed, an identification result corresponding to the picture of the equipment, a lockset operation result and/or the like.
In the embodiment of the invention, the operation ticket is automatically generated, checked, audited and output by being in butt joint with the power grid dispatching operation management system, the power grid management information system, the geographic information system, the power distribution automation system, the intelligent lock control system and the power grid artificial intelligent platform, the billing efficiency of the operation ticket is improved, the real-time acquisition and the real-time error-proof check of the equipment state are realized by monitoring the execution process of the operation ticket, and the safety level of the operation of the distribution network is improved.
