Embodiment

[0052] The method for high-frequency acquisition of steel coil data and precise length matching provided by the present invention includes:

[0053] (1) High-frequency data acquisition technology

[0054] The company's product FDAA high-speed acquisition device supports common communication protocols for PLC control equipment such as Siemens S7 series, Simatic TDC, Allen-Bradley Control Logix series, GE PAC&HPC, including TCP / IP, UDP, Profibus-DP, OPC, Reflective Memory, S7- TCP, Profinet and other data collection methods.

[0055] The maximum sampling period of PLC data can reach 8ms (depending on the specific PLC model and the communication protocol used), and the fastest sampling period of the hardware data collector can reach 1ms. Ability to monitor any signal you want, such as voltage, current, temperature, speed, tension, pressure, etc.

[0056] With the support of FDAA high-speed acquisition device, it provides high-speed and accurate data guarantee for collection and...

Abstract

The invention provides a steel coil data high-frequency acquisition and accurate length matching method and system, and the method comprises the steps: high-frequency data acquisition: acquiring signals, including voltage, current, temperature, speed, tension and pressure, through an FDAA high-speed acquisition device; a length accurate matching step: performing weld seam synchronization according to the collected signals and a synchronization principle; and a data storage step: carrying out data storage on the collected signals according to different dimensions. According to the invention, the current steel coil production data is dispersed to a plurality of systems for data integration, so that the data utilization efficiency is improved; according to the invention, the PLC data is acquired at one time, and the increase of the PLC load and development cost caused by repeatedly acquiring the data from the PLC by a new system is reduced.

Description

technical field [0001] The invention relates to the technical field of data collection and matching, in particular to a method and system for high-frequency data collection and precise length matching of steel coils. Background technique [0002] The modern steel rolling production process has very high requirements for the quality of the products, and the existing data related to steel coils are scattered in various systems, the names of the data are not uniform, and the data accuracy is poor, which brings great challenges to the comprehensive application of these data. difficulty. [0003] The advanced industrial organization method uses data to organize production and the entire industrial chain, but many manufacturing companies organize production according to physical assets or functions. Modern manufacturing in the true sense is the digitalization of the entire supply chain and the entire process. All functions are connected, and the supply chain is inseparable from s...
