Single-side data point uploading synchronization method based on a 104 protocol communication heterogeneous system

Abstract

The invention discloses a single-side data point uploading synchronization method based on a 104 protocol communication heterogeneous system. The method comprises the following steps that: a single-side point table function is defined; the substation receives the starting frame and sends a starting confirmation frame to the master station, the substation is started to carry out data transmission after the starting confirmation frame is checked to be correct, the main station side writes a database description file into the received single-side point table, and writes a single-side point table check report; and data point table synchronization processing is performed according to the difference condition. Based on a unilateral data point table uploading method and a data point difference automatic matching function, the load of maintenance personnel is greatly reduced, the working efficiency is improved, meanwhile, the safety and reliability of data synchronization of the centralized control side dispatching master station and the plant station side substation are improved, and the risk of a manual point table comparison and synchronization mode is reduced. The method can also adapt to the difference between a master station heterogeneous system and a substation heterogeneous system, and rapid synchronization of data point tables of the heterogeneous system is achieved.

Description

technical field [0001] The invention relates to the technical field of data synchronization, in particular to a synchronization method for unilateral data point uploading in a communication heterogeneous system based on the 104 protocol. Background technique [0002] With the construction of cascade centralized control centers in domestic river basins, a large number of hydropower stations have been connected to the cascade dispatching computer monitoring system, further realizing the "unattended and few people on duty" of hydropower stations. The task of the monitoring system on the centralized control side is to remotely monitor and control the operation of key facilities and equipment such as cascade power stations and flood gates, and to carry out joint hydropower dispatching for cascade power stations in accordance with the dispatching instructions of the superior, and to implement unified dispatch management for cascade power stations. According to the task requirement...

AI Technical Summary

Problems solved by technology

[0004] In the traditional communication program between the centralized control side and the plant side, due to the inconsistency of the data point identifiers defined in the databases on both sides of the communication, both parties need to maintain an agreed communication point table, that is, agree on the serial number and meaning of the data point, Once a dislocation is formed, it will cause data error

For the watershed cascade dispatching monitoring system, the power station monitoring system and the centralized control monitoring system use monitoring system software from different manufacturers, resulting in a large difference in the monitoring system architecture

Therefore, the current maintenance of the communication information point tables on the main station and sub-station sides can only be manually compared and synchronized one by one, which greatly reduces the work efficiency of maintenance personnel, and the manual comparison method is unreliable and unsafe.
