In consideration of ihe fact that the frequent pollution incidents have brought great losses to the aquaculture in Hongze Lake, a data collection and pollution monitoring system was proposed. With the embedded S3C2410 and MAX197 chips, the system realizes the process of multi-channel data acquisition and monitoring. According to the characteristics of different analog channels, the system can use different signal input range and sampling mode to realize diversified sampling and data collection of different range by the control word. In addition, after effectively collecting multi-channel pollution signal detected by the sensors, the system can send the primary data of water quality to the PC or central server by GPRS module after package for the follow-up processing and analysis, so as to meet the requirements of the real-time monitoring of water quality and realize the automatic monitoring of pollution parameters. The whole system has higher practicality and reliability with low energy consumption and low cost, it will become an effective method for the data acquisition and pollution monitoring of the aquaculture industry in Hongze Lake.%针对洪泽湖污染事件频发且对水产养殖业已经造成重大损失的现状,提出一种专门针对洪泽湖水产养殖污染环境的数据采集及监测系统.该系统主要利用嵌入式S3C2410及MAX197芯片实现了对多通道污染信息的数据采集与监测过程,可以根据不同模拟通道的特点,通过MAX197的控制字,不同的信号输入范围和采样模式实现多样化采样方式和不同量程的数据采集.另外,在有效采集由污染检测传感器测得的多路污染信号之后,系统能够将各水质原始资料数据封装并通过GPRS模块发送给上位机或中心服务器进行后续的处理分析,从而满足了水质数据实时监测要求,实现对污染参数的自动监测.整个系统的成本低功耗低,具有较高的实用性和可靠性,将会成为洪泽湖水产养殖污染环境数据采集与监测的一种有效手段.
