The diagnostic rule format of the rule base is: when the secondary equipment operation state is in the operation/maintenance state and the alternate primary equipment operation state is in the operation/hot standby/cold standby/maintenance state, the pressing plate should be put in/taken out. The clamp plate is including overhauing clamp plate, SV receiving clamp plate, GOOSE and sending the clamp plate, GOOSE receives clamp plate and protect function clamp plate.
Taking a differential protection soft pressure plate of a channel involved in a diagnosis rule of line protection as an example, the alias key keyword of the pressure plate is "S _ default.b _ default.line _ default.rly _ default.funcen _ ena1. stval".
When an instantiation rule of some actual equipment is generated, the pressing plate needs to be automatically mapped, and firstly, corresponding station information and primary equipment information protected by the protection device are retrieved from a database according to basic information of the equipment; then, based on the primary equipment information, the interval where the primary equipment is located and the corresponding Line equipment information can be retrieved, so that the instantiations of fields such as 'S _ Default', 'B _ Default', 'Line _ Default', 'Rly _ Default', and the like are realized, and 'funcena 1. stval' describes the attribute of the secondary equipment, and a channel-differential protection soft pressing plate under the device can be uniquely determined, so that the channel-differential protection soft pressing plate is mapped to a data object corresponding to the pressing plate in a monitoring system database.
Step three: and starting the intelligent diagnosis module, reading the diagnosis rule and diagnosing the equipment by the intelligent diagnosis module, and generating a diagnosis report if the equipment is abnormal.
When the intelligent diagnosis module diagnoses the equipment, the intelligent diagnosis module firstly acquires basic information of the equipment from the database, matches the corresponding diagnosis rule in the rule base through the equipment type, converts a data object in the diagnosis rule into an actual object in the database in an automatic mapping mode through the Aliskey key words to form an instantiated diagnosis rule of the equipment, and then compares real-time state information related to a pressing plate under the diagnosis rule with a reference value in the diagnosis rule.
The intelligent diagnosis module compares the real-time state information related to the pressing plate under the diagnosis rule with a reference value in the diagnosis rule, and if the comparison is inconsistent, the state of the pressing plate is judged to be abnormal; if the abnormal pressing plate exists in the equipment, judging that the running state of the equipment is abnormal; if the equipment involved in diagnosis is not changed compared with the equipment in the last diagnosis, a diagnosis report is not generated, if the equipment is changed, the diagnosis report is generated, and the data is transmitted to the monitoring interface module.
Step four: starting a monitoring interface module: the monitoring interface module acquires basic equipment information from the database and generates the basic equipment information into an equipment list; the monitoring interface module obtains the diagnosis report from the intelligent diagnosis module and generates the diagnosis report as monitoring information.
Step five: the monitoring interface module receives the equipment name and the diagnosis report of the intelligent diagnosis module; if the result of the diagnosis report is abnormal, the diagnosis report is notified to the monitoring interface module; if the diagnosis result of the diagnosed equipment is changed from normal to abnormal, the corresponding equipment is lifted to the forefront of the list in the left equipment list of the interface of the warning display equipment, a warning icon is added in front of the equipment name and is set to be in a selected state, and the monitoring information of the equipment is synchronously displayed on the right side of the interface of the warning display equipment. The abnormal device will always remain in the front of the device list until its diagnostic result becomes normal.
These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart or flowcharts.
