Realization method of remote retrieval of in-situ intelligent management unit based on master station mode

Abstract

The invention discloses a method for realizing remote retrieval of an in-situ intelligent management unit based on a master station model, including: 1) according to the menu model specified in the management unit modeling specification, the data set and the menu model in the database are processed during the storage process. The data items are screened to ensure that the menu items are complete and the data items are not repeated; 2) The remote access module uses the main sub-station mode to access the sub-station server of the local intelligent management unit, and the sub-station server accesses the database to obtain the menu information of the device Upload to the remote access module; 3) The remote access module adopts the client cache mechanism to cache the configuration of the menu; when the value configuration in the menu changes, the remote access module reads the configuration from the sub-station server. The remote interface module of the present invention is a C / S development mode, which can separate data sources through the network mode, has strong deployment flexibility, and high degree of concurrency, and is suitable for the development and debugging of localized equipment to meet the needs of multiple people for interface operations.

Description

technical field [0001] The invention relates to the technical field of electric power system relay protection, in particular to a method for realizing remote retrieval of an in-situ intelligent management unit based on a master station mode. Background technique [0002] It is recorded in "Application and Practice of On-site Protection without Protection Installation" that with the development and installation of on-site unprotected relay protection equipment, an intelligent management unit for on-site protection (may be referred to as the management unit for short) is set up at the station control layer , providing a means of human-computer interaction, and at the same time realizing the centralized configuration function of all protection devices. In other words, the on-site intelligent management unit is a new management information system deployed at the station control layer during the process of unprotected installation and on-site protection and application. The on-s...

Problems solved by technology

At present, the local management unit is usually developed on the basis of the credit system. The remote access of the management unit can be directly developed as a local application module. Before the data enters the data server of the management unit, it can be updated to the remote access module. The reading module does not even depend on the Baoxin database. This development mode has the advantage of fast data update speed, but this development mode is highly coupled, and the original system architecture of the Baoxin system has been greatly modified, so that the system does not have general attributes. ; and the remote access module must be deployed on the same hardware as the management unit. Adding a remote debugging module requires adding a management unit device. The hardware cost in the early stage is relatively high, which makes debugging and development inconvenient
