基于ARM的水体溶解氧监测系统设计

Design of DO monitoring-system based on ARM

为了实时了解水质溶解氧(DO)含量,准确掌握水文动态,设计了基于ARM的DO监测系统。以ARM 920TS3C2410为主控制器,运用最小二乘法温度补偿原理及嵌入式技术对DO参数进行实时采集、处理及远程传输。测试结果表明,该系统监测准确,运行稳定,实现了对水体DO的实时监测。

In order to monitor DO in real time and accurately grasp the hydrological dynamics, this paper studies a DO real- time monitoring-system based on ARM. Combined with embedded technology and temperature compensation of least-square method, the system employing the ARM processor 920TS3C2410 as the core, acquires, processes and transmits DO multiparameter. Experimental results show that this system can in real time detect DO of water.
