Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0056] The present invention will be further described below by taking the process control system of a certain high-speed bar workshop as an example.

[0057]The process control system periodically collects first-level measured process data, mainly including the speed, current and other measured data of each rack, a total of 46 single-precision floating-point values. According to the process requirements, the acquisition period is 500ms, assuming that the rolling time ratio is 75% per day, so that 2*3600*24*0.75≈130,000 pieces of data will be generated every day. Generally speaking, the process control system needs to ensure ...

Abstract

The invention discloses a high-speed data storage method and system for steel process control. The method includes the following steps: 1) according to process requirements, determine a total of M data points that need to collect data and the upper limit of the data value corresponding to each data point and lower limit; divide the data points into N groups, and then create a table in the relational database; 2) data acquisition: the process control collects the actual values ​​of all data points from the basic automation; 3) data conversion and caching; 4) judge whether it is satisfied Storage conditions, if the storage conditions are met, go to step 5), otherwise go to step 2) and wait for the next data collection; 5) Data storage: save all the second-type data packets cached in the shared memory to the database table with a record middle. The method of the invention has simple implementation process, high efficiency in operation, and rapid response under the condition of ensuring high-speed storage of process control.

Description

technical field [0001] The invention relates to data storage technology, in particular to a high-speed data storage method and system for steel process control. Background technique [0002] The iron and steel industry generally adopts a hierarchical computer control system, including the first level of basic automation, the second level of process control, and the third level of manufacturing execution. Material tracking is the core function of process control, including location tracking and information tracking, used to determine the production process data and consumption data of specific materials. This function has positive significance for optimizing the production process, improving product performance, saving energy and reducing consumption. [0003] The process data and consumption data of the second-level process control come from the first-level basic automation. For some process control computer systems, it is enough to collect data from the basic automation s...
