Large-scale centralized control system telemetering windstorm intelligent processing method

Abstract

The invention discloses a large-scale centralized control system telemetering windstorm intelligent processing method. The method includes the steps that firstly, telemetering data general tables of a whole centralized control system are classified, and telemetering data are divided into multiple grades according to priority; secondly, a telemetering priority classification table is defined; thirdly, according to the telemetering priority classification table, a communication manager or a communication device of the centralized control system conducts priority scanning on changed telemetering points of a whole station; fourthly, the communication manager or the communication device sequentially sends the telemetering data of the changed telemetering points according to the priority. The telemetering data general tables of the whole centralized system are classified, the telemetering data are divided into multiple grades according to the priority, the telemetering priority classification table is established, when the system detects that the telemetering data change, the telemetering data are compared with data on the telemetering priority classification table, the communication manager or the communication device of the centralized control system sequentially sends the telemetering data according to different centralized control communication protocols and the priority, and then the purpose of system telemetering windstorm intelligent processing is achieved.

[0002] With the continuous and rapid development of the domestic economy, especially the continuous emergence of large-scale new energy projects, factories, mines, and petrochemical projects that support rapid economic development, the measurement data in the project has increased significantly. The information processing of a large number of measurement data in the entire project is a monitoring system. Data integration manufacturers urgently need to solve the problem. In the past, the measurement data did not consider the priority, and the mode of uploading when there is a change can no longer meet the needs of large-scale monitoring systems for data integration and processing.

In a large-scale monitoring system that changes telemetry into a storm, it may take tens of seconds or even a few minutes for the measurement data to go from the data acquisition device to the communication processing device and finally to the human-computer interaction interface. The slow refresh rate of some important measurement data may cause The potential safety hazards in the production process cannot be discovered in time or the production process cannot meet the specified requirements, which will have an extremely adverse impact on the production of large enterprises. This also puts forward higher requirements for monitoring system integration manufacturers. Faced with massive measurement change data And the user's strict requirements on the refresh rate of monitoring system measurement data is also an urgent need for safe production. Monitoring system integration manufacturers urgently need a method to solve the bottleneck problem of telemetry data transmission
