High-Speed Data Acquisition Design and Implemention That Is Based on S7-300plc and Wincc

Abstract

Information technology has become a consensus today, at the same time, we need to integrate and deal with the huge data. Especially in some specific areas, such as rapid reaction system, the whole reaction process is less than 5s. To analyze the entire reaction process to understand the parameters of the change, even with the 500ms sampling cycle, the data collection is still too little. In this case, resource consumption on the machine for communication with the controller system has been very high, coupled with data processing, images, database tasks and etc. When the scale of variable size is not much, the host computer load has been overwhelmed. The use of acquisition board to achieve high-speed data acquisition is limited by the size of the entire system limitations, and also because of the number of computer expansion slot restrictions, the final number of points are dozens. Based on the above problems we combine s7-300PLC with WinCC for high-speed collection of information to achieve the value of large data extraction.
