Problems solved by technology

The traditional method of saving process data is to save the data into a certain file and then display it in the form of a curve for the analysis of the production process. The analysis process is based on the trend curve formed by historical data, and the on-site production process problems are carried out point by point. The analysis cannot realize the process of pushing historical data to the corresponding process control system for offline production process simulation, analysis and optimization

Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the system and method will be described in detail below taking the continuous casting process control system as an example and referring to the accompanying drawings.

[0035] In the continuous casting process control system, it generally takes 8‐10 hours for a casting from start to finish. In the continuous casting process, the crystallizer is an important equipment in the continuous casting process. During the debugging stage, the fastest acquisition of crystallizer vibration data can reach 10ms. There are about 2,000 conventional data collection points, including data such as data related to large ladle tundish, water flow information of primary cooling and secondary cooling, and casting speed. Through the system and method, online data collection, storage compression and offline operation of the control system, offline acceleration of data, and single-frame playback mod...

Abstract

The invention provides a data collection playback system and method in an industrial production process, and relates to the technical field of data collection and processing playback. The system and the method aim at the problem that process personnel cannot realize the playback on data in the production process under the normal condition. The playback system comprises a parameter configuration module, a real-time database data collection and compression storage module, a playback control module and an event capture module. According to the playback method, data points requiring collection and playback are configured, the data is subjected to graded collection storage and compression, and historical data is subjected to playback. The playback system and the playback method have the advantages that on the premise of not increasing the hardware equipment, the fast data collection, the layered processing storage processing and the production process playback are realized, and important effects are achieved on analyzing the problems in the production process and optimizing parameters.

Description

technical field [0001] The invention relates to the technical field of data acquisition and processing playback, and relates to a method for enabling a process control system to realize playback of a production process without being separated from on-site equipment. Background technique [0002] In a modern process factory, there is a secondary process control system for each production link. However, in the past production process, the secondary process control system is generally only used for calculation in the online production process, and the results are sent to the primary equipment to realize the automatic control of the production process. The secondary process control system performs model calculation and data delivery, and the primary PLC executes the data after receiving the data from the control system and returns the execution result to the secondary process control system. The traditional method of saving process data is to save the data into a certain file a...
