The Design of Embedded Single Chip Network Measure and Control System

摘要

This article introduces a type of embedded single chip network measure and control system based on Ethernet, which adopts high speed single chip 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 an 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 intelligent sensors and has better expanding ability. It can be used in the fields of powder object temperature measurement remote data acquisition, remote measurement and control and so on.
