Description

IBAPDA-based data acquisition system

Technical Field

The application relates to the technical field of data acquisition, in particular to a IBAPDA-based data acquisition system.

Background

IBAPDA is a system for collecting and analyzing data based on PC, which mainly comprises distributed hardware for signal collection, connecting optical fibers and other media (propibus-dp, profinet, etc.), standard industrial computer board card and on-line and off-line analysis software, and the measured data is customized in a computer hard disk. Due to its software friendly user interface and dynamic display function, it is widely used in rolling production automation systems.

In terms of software use, the following two main functions are mainly used: (1) Data signal tracking, namely judging whether equipment has a problem in control or not on a time domain spectrogram by adding and collecting data signals according to the existing logic control program; (2) And after the problem analysis and judgment are carried out on site, opening the stored data by using offline analysis software, and analyzing related signal points on a time domain spectrum line by combining site fault phenomena to finally determine the cause of the problem.

Because the programmable controller of the conventional rolling automatic control system takes 300 and 400 series PLC as the main components, when the IBAPDA system software is utilized to carry out addition storage and monitoring analysis on related control signals, the self S7 ANALYSER TCP/IP communication protocol is directly adopted, and the addition, data storage, real-time monitoring and offline analysis on related signals in the whole automatic control can be realized by simply establishing connection with the appointed PLC by only accessing the PC host into the local area network of the automatic control system in an Ethernet mode.

With the gradual development and updating of the programmable controller, the 300 and 400 series are not withdrawn from the production sequence, but the 1200/1500 series with higher cost performance, stronger function and better motion control are gradually used for replacing the 300/400 series when the equipment is selected. Along with the popularization and use of 1200/1500 series controllers, IBAPDA clients cannot continuously adopt the original S7 ANALYSER TCP/IP communication protocol to realize the monitoring and storage of PLC data signals, accordingly, trouble is caused to the analysis and judgment of on-site problem reasons and the real-time monitoring of signals, repeatability problems are easy to occur, a plurality of uncertain factors are brought to the stable operation of production rolling, and the method is contrary to the requirement of high-precision management of the existing equipment.

Therefore, how to provide a data acquisition system based on IBAPDA to realize data communication of the existing programmable controller and ensure that IBAPDA client machine can acquire data signals stably is a technical problem to be solved at present.
