Traditional industrial control system mainly use the PLC and DCS as the control equipment,but the high control cost and bad real time make them difficult to meet the requirements for the control system of the development of modern industry.However,the embedded control system is widely applied in industrial field as its low cost,high performance and good real-time performance advantages. We designed an industrial control system based on embedded system,including data acquisition system,communication system based on Bluetooth module,and with ARM9 as the main controller completed an industrial GUI through Qt4 programming under Linux operating system. The data collected data were amplified,linearized,and filtered by the acquisition system of modular,then after A/D conversion of C8051,transferred through the bluetooth communication technology to the main controller for data processing and the processed data get back to the industrial field through bus. Tests prove that the software for data processing is of high precision,fast speed,good real-time performance and can meet the requirements of industrial application.
