%X For this development, computer technique was applied to the sampling instrument to realize the mankind-machine interaction, and to achieve the goal of intelligentialization. Some reliable, lower cost elements for water sampling, memory and convention were used to realize auto-sampling. The control system of this sampling instrument adopted a monistic microprocess. The 8031 chip was used as a microprocessor, coordinated with peripheral interface circuits and function keyboard,to make it compact and low cost. The sampling and storage system consists of a wriggle pump, electromagnet, machenical transfer devices, water sample storage tank and container. This system has a simple structure with a smooth and steady operation and can be operated continuously or intermittently. Sampling time, sampling period and sampling bottle switching can be adjusted arbitrarily to collect water sample accuratly, reliably and conveniently.
