Historical data playback method and device based on SCADA configuration visualization

Abstract

The invention discloses a historical data playback method and device based on SCADA configuration visualization. The historical data playback method specifically comprises the following steps: S1, setting condition parameters on an SCADA module of a human-computer interface by a user; s2, correspondingly comparing parameters of the historical data with condition parameters set by a user; s3, extracting historical data meeting requirements from the unstructured data, publishing the historical data through MQTT, and subscribing and displaying the historical data in an SCADA module; step S4, enabling the SCADA module to display the received historical data through playback. According to the invention, the problems of difficult historical data reading, low reading efficiency and influence on customer experience caused by many acquisition points, short acquisition time period and large data volume in a control site in the prior art are solved; by using the function, the historical data can be quickly and accurately searched according to the modes of time, speed, progress bar dragging and the like in the historical data playing process like video playing.

Description

technical field [0001] The invention belongs to the technical field of data reading, and in particular relates to a historical data playback method and device based on SCADA configuration visualization. Background technique [0002] With the development of modern industry, manufacturing enterprises are getting bigger and bigger, and production technology is becoming more and more complex. Therefore, it is necessary to monitor the entire production process and centralize the management of scattered instruments, meters, controllers, etc., resulting in Industrial configuration software, which is a set of industrial automation software integrating management and monitoring, is widely used in electric power, energy, petrochemical, intelligent manufacturing and other industries. At present, mainstream industrial configuration software products at home and abroad generally provide historical data reading functions, but they are generally historical data curves or data lists, which ...
