摘要
针对目前河湖水质监测方法落后和水体富营养化评价方法有限的现状,研发了一套以基于ARM单片机为主控制器,融入GPS技术和GPRS技术的浮标水质远程监测系统。实现了同时对水质信息、气象信息和地理位置的实时性采集,并有云台网络摄像头进行实时视频监控,在采集后将信息短信推送到用户手机或向上位监控系统远程传输。上位监控系统对数据进行复杂分析处理和综合智能管理,以实现实时数据显示等功能。同时,采用优化的层次分析法获取相关指标权重,对水体富营养化程度进行评价,评价效果良好。浮标水质远程监测系统为水质监测提供了一个方便、有效地平台。
Aiming at the backward method of the present water quality of monitoring and the present situation of the limited eutrophication assessment method, we have developed a set of buoy remote water quality monitoring system, which mainly based on ARM MCU controller and integrated into the GPS and GPRS technology. The system is equipped water quality monitoring sensor and small station, including the wind speed and direction sensor, rain sensor, as well as light sensor, which can collect water quality information, meteorological information and geographic position at the same time, before gathering them up for a remote transmission to user's phone or upper monitoring system. And it can accomplish the real-time monitoring by cloud platform webcam. In addition, taking the security of the buoy in lakes and rivers into consideration, it is equipped with beacon light and radar reflector. The whole buoy system is adopted layered design, divided into 3 layers, which ensures convenience and effectiveness of monitoring. Besides, it is the placement of instrument cabin and water quality sensor in the buoy body that improves the security in monitoring. Upper monitor system is used the modular design concept, encapsulating different system functions into multiple subsystems. It can cooperate with the hardware system for real-time monitoring information after receiving package according to the established format, have a processing of complex analysis to data and be integrated intelligent management, for achieving real-time data display, as well as other functions. Meanwhile, optimized analytic hierarchy process is used to obtain relevant index weight and evaluate the degree of eutrophication of water, and the evaluation result is good, which provides an effective solution for the eutrophication assessment. Buoy remote water quality monitoring system provides a convenient and effective platform for the water quality monitoring.
