基于网络化控制的数据采集系统

his paper introduces a general data acquisition system which is applied to technological process industry field, for example, chemistry, food, medicine industry and so on. The data acquisition points of these industry fields have the characters of wide scope and long distance. The system is composed of data acquisition layer which is developed with MCU, data processing layer which is developed with PLC and data control layer which is developed with computer. The system can acquire and control the long-distance and real-time industry dada of the production process, for instance temperature, pressure and flux etc. This system is a network data acquisition and control system with low cost and high performance. The system can increase the automation level of the production process, improve the enterprise management and heighten the production efficiency. The system is practicality.
