一种自动水质数据采集系统已在加利福尼亚大学戴维斯分校研制出来。这种以一整套微处理机为基础的系统包括1台微记录器、1个气象测量站和1只独特的采水样浮箱。根据程序,该系统可常规监测并记录下述信息:(a)包括太阳辐照度、光合活动辐射、风速、风向、气温、相对湿度以及降雨量在内的气象数据。(b)在最深为175厘米的8个深度范围内所获得的池塘环境数据。包括溶氧量、温度、pH值以及光合活动辐射。本文叙述了数据采集系统在水产养殖研究中的使用,今后可能的改进,以及为用于其它水质的有关研究而进行的修改。
An automatic water quality data acquisition system has been developed at the University of California, Davis. The system, which is based on a complete microprocessor system, consists of a micro-logger, a meteorological measurement station and a unique water sampling pontoon. The system routinely monitors and records the following information according to the procedure: (a) Meteorological data including solar irradiance, photosynthetic activity radiation, wind speed, wind direction, temperature, relative humidity and rainfall. (b) Pond environmental data obtained over 8 depths up to 175 cm. Including dissolved oxygen, temperature, pH and photosynthetic activity radiation. This article describes the use of data collection systems in aquaculture research, possible future improvements, and modifications to relevant studies for other water quality.
