| Abstract: | PLC is proposed as the core of signals acquisition and control system to improve its anti-jamming ability in industrial environments.User interface is designed,in the developing environment of C++ Builder with host computer,to display real-time data and to keep the historical data.This paper introduced the outline of data acquisition and control system base on PLC,and the method of serial communication.The result of test shows that the system can complete the data acquisition accurately.The system has been successfully applied to auto-detection system for gas heating boiler. |
