Problems solved by technology

[0005] The purpose of the present invention is to provide an industrial real-time data acquisition system, which solves the problem that the existing industrial data acquisition system only provides the acquisition interface but does not store it or uses an expensive real-time database for storage, so that the use also requires high-demanding secondary data acquisition for the interface. The first development will collect data and store it, which is very costly

Embodiment 1

[0035] Example 1: figure 2 It is a block diagram of the raw material ratio and consumption data acquisition system of the sintering plant of Hebei Puyang Iron and Steel Co., Ltd. The acquisition front-end collects 265 sintering plant feeding data, 265 sintering plant control data, 180 sintering plant feeding data, 180 sintering plant control data, and transmits the collected data to the acquisition end through the Siemens S7-400PLC model acquisition front-end for buffering , verification, preprocessing and filtering, and store it in the first-level storage database (SQL Server), filter and summarize the data, store it in the second-level storage database, then filter and summarize the data, and read out the application from the client terminal in the data reporting system.

Abstract

The invention discloses an industrial real-time data collecting system. The real-time data at an industrial collecting front end is collected by client software on a computer. The data stored in a primary database is collected and screened through data screening software, the screening result is stored in a secondary database, and a terminal user can read or call data in the secondary database or call the collected data stored in the secondary database at anytime. The industrial real-time data collecting system has the advantages that multi-level data distribution storage is used for data storage, pressure of a single data storage sever is reduced, expensive real-time databases are not needed, cost is lowered, data can be read from multiple servers at the same time due to distribution storage, and data reading efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of industrial data acquisition, and relates to an industrial real-time data acquisition system. Background technique [0002] With the gradual improvement of the degree of industrial automation, various field data (temperature, flow, switching value, etc.) are increasing exponentially, so the management and statistical analysis of these discrete data has become the responsibility of the field and relevant departments. The biggest headache. [0003] Use data collection to transmit the effective data on site to the background database server in real time, which provides the basis for the next step of management and statistical analysis. At the same time, the centralized storage of data provides a data basis for process improvement, hidden danger investigation, and fault analysis. [0004] At present, most of the similar acquisition systems only provide acquisition interfaces without storage or use expensive ...
