Safe region-crossing equipment uniform monitoring method based on independent monitoring services, and monitoring system for the same

Abstract

The invention discloses a safe region-crossing equipment uniform monitoring method based on independent monitoring services, and a monitoring system for the same, which are used for safe region-crossing equipment comprehensive monitoring of a power dispatching automation system. The monitoring services are independently arranged and run in different safe regions, a global unique production mechanism of the instance identifiers of resource, warning and performance models is used, timely collection of the safe region-crossing equipment resource, warning and performance information in a safe III region monitoring service is realized, and a III region monitoring client monitors and manages the equipment uniformly. With the method, the independently arranged monitoring services have basic capabilities in resource model management, equipment warning basic analysis and management, and performance data processing, thus, data redundant transmission through a physical isolation device is reduced, some of the pressure on the III region uniform monitoring service is shared, and finally, the safe region-crossing equipment uniform monitoring is finished.

Description

technical field [0001] The invention relates to an independent monitoring service-based device unified monitoring method across security zones and a monitoring system thereof, which belong to the field of electric power system and information technology. Background technique [0002] At present, the power dispatching automation system generally adopts the following methods for the monitoring of secondary equipment cross-safety areas: 1. Separate monitoring of equipment in safety area III (information management safety area) and safety I / II area (production control). The monitoring service of each security zone is an independent system, which provides all services from equipment information collection, data storage, to client monitoring and display. This monitoring method cannot meet the requirements of unified monitoring across security zones because the monitoring information of devices across security zones cannot be integrated. 2. Unified monitoring of equipment in safe ...

AI Technical Summary

Problems solved by technology

This monitoring method transmits all the original data collected by the front-end processor to the supervision server in Zone III, which results in redundant data transmission, especially for the front-end processor collection service in the periodic polling mode, the same alarm data generated will be Repeated transmission, equipment monitoring information that has not changed will also be transmitted repeatedly, thus increasing the data transmission volume of the physical isolation device and increasing the data processing pressure of the supervisory server in Zone III

On the other hand, because the collection front-end processor does not have basic resource model management, device-level alarm analysis and performance data processing capabilities, it cannot share the load of the unified supervision server in Zone III

As the number of devices included in the monitoring increases, the processing performance bottleneck of the monitoring server in Zone III will be formed, which will affect the timeliness of the overall device alarm notification and the display effect of monitoring information
