基于以太网模块IP传感器的研究

Resarch on IP Sensor Based on Ethernet Module

对于工业现场设备的监测控制,人们不再满足于集散控制系统和现场总线控制系统,为此,结合传感技术和Internet技术,将传感器制成网络产品,并实现网络通信TCP/IP协议。该文系统地介绍了IP传感器、TCP/IP协议及其实现原理,阐述了以太网通信模块的实现方案、软件设计,给出了网卡的复位及初始化事例。所研制的IP传感器具有远程数据访问、信息实时发布与共享以及在线编程等功能,为构建具有更高性能价格比的测控自动化系统成为可能,该模块在远程自动化领域具有广阔的应用前景。

People are no longer to settle for distributing center control system and field-bus control system to monitor the industrial field equipment. Therefore, the sensor technology and internet are adopted to develop IP sensor and realize TCP/IP protocol. The paper systematically introduces IP sensors, TCP/IP protocol and its realizing principle, sets forth implementations project of Ethernet communication module and its software design, and gives the practical examples of reset and initialization of network card. The developed IP sensor has functions of remote data access, real-time information issuance and on-line programming, which make it possible setting up the testing automatic system with a higher cost performance. This module has the wide application prospects in the field of the remote automation.
