Ethernet-based Network Measure and Control Systems Embedded MCU

This article introduces a type of embedded MCU network measure and control system based on Ethernet, which adopts high speed MCU with kernel of 8052. Through controlling the special chip for Ethernet, the system realized the function of TCP/IP protocol. Since the system can be used as a independent system, any computer on the net can control the system or transmit order and data to the system through standard TCP/IP protocol. Equipped the system by digital temperature sensor, it can be used to measure industry field temperature and transmit the results to computer through network, and then get temperature curve. And its measure and control range are all -10~+125°C, the accuracy is ±1°C, the resolution reaches 0.1°C. This system have many advantages such as simple structure, better universal, communicating through network, flexible usage, low cost etc. It can be adapted by various of intelligent sensor and has better extend ability. It can be used in the fields of remote data acquisition, remote measurement and control and so on.
