Problems solved by technology

The monitoring screen can display operating data and equipment operating status in real time, and provide functions such as command issuance and locking. Therefore, the real-time refresh function of the monitoring screen is particularly important. In the prior art, the monitoring screen mostly adopts the layer single-point update mode. The point data source directly queries the screen database and updates the data. When there are many screen measurement points or the refresh frequency is high, frequent access to the screen database may lead to excessive data traffic, which affects the real-time acquisition of screen data and causes problems such as screen freezes.
In addition, most of the existing monitoring screens only support the same screen refresh cycle, and do not support setting the screen refresh cycle by layer, which has a certain impact on the screen refresh quality

Abstract

The invention discloses a DCS monitoring screen refresh method, system, equipment and readable storage medium, which traverses the screen layers and establishes layer data sets; traverses all layer data sets, and establishes corresponding data sets for each layer The layer refresh buffer; according to the refresh cycle of different screen layers, respectively establish a layer refresh thread, and establish a thread refresh buffer for the layer refresh thread according to the established layer refresh buffer; start all the layer refresh threads established , for each layer refresh thread, periodically refresh the layer according to the refresh cycle. The invention can improve the running stability of the picture and the refresh rate of the data of the measuring point of the picture.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method, system, equipment and readable storage medium for refreshing DCS monitoring images. Background technique [0002] In the distributed control system of a thermal power plant, the operator completes the overall monitoring of the distributed control system and the issuance of control commands through the monitoring screen. The monitoring screen can display operating data and equipment operating status in real time, and provide functions such as command issuance and locking. Therefore, the real-time refresh function of the monitoring screen is particularly important. In the prior art, the monitoring screen mostly adopts the layer single-point update mode. The point data source directly queries the screen database and updates the data. When there are many screen measurement points or the refresh frequency is high, frequent access to the screen database may cause excessive ...
