基于TCP的集散式环境参数测量系统的设计与实现

Design and Implementation of Distributed Measurement System for Environmental Parameters Based on TCP

为保证分散测点的独立测量与精确控制,同时数据可及时传送到监测中心进行环境状况分析,设计基于TCP的集散式环境参数测量系统,对温度、相对湿度、气压等参数进行测量;采用TCP的SOCKET接口网络通信技术、数据采集技术及面向对象开发技术,利用现有的局域网资源,以高性能价格比实现信息的实时获取、控制,实现信息、资源及任务的综合共享和全局一体化管理;该系统经长期运行,稳定可靠,达到了设计的要求。

In order to assure the environmental parameters at dispersed spot is measured independently, controlled accurately and the acquired data can be transmitted to monitor center timely to give circumstance status analysis, a distributive system for environmental parameter measurement and control based on TCP is designed to measure the parameters of temperature, relative humidity and pressure, in which the technologies of network communication by SOCKET interface, data acquisition, object oriented software development are adopted. Real time data acquisition and control based on existing local area network with high cost performance and integrative share and management of information, resources and assignments are implemented. A long time reliable running proved the system design in accordance with the requirements.
