摘要 近几年，随着GPRS技术日渐成熟，PLC功能的不断扩展和更新，PLC和GPRS技术已普遍地融合于各个行业中。我国是水产养殖大国，养殖业正受到各界人士越来越多的关注。所以研究出一个无线远程监测系统对养殖业来说很有必要，这可以实现对水质参数实时、连续和稳定的监测，使养殖户全面地了解养殖水环境的状况，从而可以从根本上改善水产养殖业的生产管理。
为了促进我国水产养殖的发展，本文提出了一个基于GPRS的远程多参数测量系统，实现了对温度和溶氧量这两个水质参数的实时监测。该系统选用S7-200 PLC(CPU226)作为终端的核心处理器，配有EM235模块实现模拟量的输入输出和TD400C实现现场的人机交互，通过自由口方式与GPRS模块进行连接实现了与上位机之间数据的远距离传送；PLC编程实现溶解氧的闭环控制，对增氧泵的调速通过变频器实现。上位机与远程控制端的远程通信用VB编写。该系统给出了传感器调理电路的相关设计，实现了对温度、溶氧量的采集。文中还阐述了GPRS的通信原理和软硬件设计。
本文分别就基于GPRS无线通信多参数测量系统的工作原理，温度、溶氧量传感器的选型、PLC配置、软件程序设计等几方面进行阐述。在实际测试中，结果表明系统具有较高的稳定性和便捷性，能够实现水质参数数据的远程无线传输。PLC技术与GPRS技术的完美结合使远程测量成为了现实，它解决了远程测量存在的一些问题，而两者的结合除了带来了技术上的革命，也带来了客观的经济效益，具有良好的发展前景。

The Remote Multi-parameter Measurement System
Based on GPRS
Abstract In recent years, GPRS technology is gradually mature and the programmable controller (PLC) continues to expand and improve the function, the combination of PLC and GPRS technology has been applied more and more widely in various industry. China is a big country of aquaculture, so a wireless remote monitoring system is necessary to the breeding, because it can realize the real-time, continuous and stable monitoring of the water quality parameters, and also make the farmers fully understand the condition of aquaculture water environment, so they can fundamentally improve the production management of and the aquaculture. It helps people to master the real-time water environment parameters and the remote control of them and it is conducive to the improvement of aquaculture environment.
In order to promote the development of aquaculture in China ,this paper presents a remote multi-parameter measurement system based on the GPRS. The system realizes the real-time monitoring of water quality parameters, such as the temperature and the amount of dissolved oxygen. The system selects S7-200 PLC (CPU226) as control terminal with EM235 module for analog input and output and TD400C for human-computer interaction. PLC through the way of free port connects to GPRS module for data transmission between the upper computer and the control terminal. Loop control of dissolved oxygen realizes by PLC program. It adjusts the speed of the oxygen pump through Variable-frequency Drive. The remote communication between upper computer and remote control terminal is written with VB. The system presents the design of sensor conditioning circuit, and it realizes the acquisition the temperature, the amount of dissolved oxygen. This paper also gives the communication principle of GPRS communication module and the design of software and hardware of it.
The paper introduces multi-parameter measurement system based on GPRS wireless communication including working principle, temperature and dissolved oxygen sensor, PLC configuration, software design and so on.In the actual test, the result shows that the system has high stability and convenience and it can realize remote wireless transmission of the data water quality parameters. The perfect combination of PLC technology and GPRS technology makes the remote measurement become a reality. It solves the various problems of the remote measurement, and the combination of the two brings the technology revolution, also brings the objective economic benefits. The system has good prospects for development.
