【摘要】 介绍一种基于以太网的嵌入式单片机网络测控系统,它采用具有8052内核的高速单片机,通过对专用以太网芯片的控制,在以太网上实现了TCP/IP协议的功能,可作为以太网的一个独立系统,网络上的任何一台计算机都可通过标准的TCP/IP协议对其进行控制,传输控制命令或数据。将该网络测控系统配上数字温度传感器后实际测量工业现场温度,然后通过网络传输给计算机,可获得温度曲线,其测温范围与控温范围均为-10～+125℃,测温精度为上±1℃,分辨力达0.1℃。该系统具有结构简单、通用性强、通过Internet进行通信、使用灵活、成本低等优点,适配多种智能传感器并具有较强的扩展能力,适用于远程数据采集、远程测控等领域。更多还原

【Abstract】 This article introduces a type of embedded μC network measure and control system based on Ethernet,which adopts high speed μC 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℃,the accuracy is ±1℃,the resolution reaches 0.1℃.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.更多还原
