| 摘 要： | 溶解氧、pH值、电导率、温度等是水质分析的关键因子，对各关键因子的实时测量尤为重要，但传统的经验检测法和化学检测法已经不能满足要求。随着传感器智能化、网络化的发展，无线网络技术在满足水质监测实时性、准确性要求方面显示出优势。ZigBee技术不仅具有距离近、复杂度低、组网能力强、成本低及可靠性高的特点，并且自有无线通信标准，可以接力的方式在多个测量节点间相互协调实现通信，充分满足了无线水质监测的需要。本文提出一种基于JN5139的ZigBee无线模块的无线水质监测系统。该系统集感知模块、微控制模块和无线传输模块于一体，通过无线网络定时收集现场测得的多路水质参数，并利用上位机存储和显示数据。用户可以通过计算机连接系统JN5139-Z01-M02/4无线模块收集现场测得的多种水质参数。在建筑物、树木等障碍物遮挡的情况下，可以达到至少100 m的传输距离。试验结果表明该系统具有可扩展性强、功耗低、稳定性高等特点，能够满足水质监测实时性和数据精度的要求。

| Abstract: | Dissolved oxygen, pH value, conductivity, temperature, etc. are key factors for analyzing water quality. And, how to measure the key factors real-timely is particularly important. It is impossible for traditional empirical methods and chemical detection to satisfy production requirements today. However, with the development of intelligent and networked sensors, wireless network technology can satisfy the requirements of accuracy and real-time in water quality monitoring. ZigBee technology not only has characteristics of short distance, low complexity, powerful networking capability, low cost and high stability, but also has self-owned wireless transmission standard in which multiple modes which can relay each other achieve effective communication in measuring nodes, which fully meets the needs of the wireless water quality monitoring. This paper puts forward wireless water quality monitoring system based on JN5139 ZigBee wireless module. The system gathers perception module, micro-control module and wireless transmission module. Multiplex water quality parameters are collected periodically by wireless network, stored and finally displayed on host computer. These data can also be checked by users after connecting JN5139-Z01-M02/4 system through computer. In case of buildings, trees and obstruction, distance accuracy is 100 m at least. According to experiments, the system has high scalability, low power consumption, strong stability and so on, which can meet the requirements of real-time and data accuracy in water quality monitoring. |
