摘要
针对环境在线监测系统中对浊度测量的要求,设计了散射式水下在线浊度传感器。传感器采用水下散射光测量法,介绍了浊度传感器的软硬件开发,包括水下浊度传感头、信号检测电路、MSP430单片机为核心的处理与控制部分及上位机程序。传感器具有水下在线测量、浊度标定、串口通信和数据存储等功能,其分辨力为0.1 NTU,精度为±2%,能满足环境在线监测系统中对水浊度测量的要求。
An on-line underwater scattering turbidimeter is designed for on-line environment inspect system. The turbidimeter bases on the scheme of scattering light measurement focuses on underwater probe of turbidimeter,data acquisition circuit,control section using MSP430 micro controller and PC application program. It has the functions of on-line underwater measurement, turbidity standardization, serial communication and data storage. The resolution is 0.1 NTU and the measurement accuracy is within 2 %. The requirements of turbidity measurement for on-line environment inspect system are achieved.
