摘要 将计算机技术应用于采样仪中,实现人-机对话,同时配以运行可靠,成本较低的水样采集、贮存和转换等部件,实现自动采样,达到智能化的目的。采样仪的控制采用单片机技术,以8031芯片作为微处理器,配以外围接口电路和功能键盘,体积小,成本低。采集贮存系统由蠕动泵、电磁铁及配套的机械传动装置、水样贮存盘和容器等组成.结构简单,运行平稳。采样有连续采样和间歇采样2种功能,并可按需要任意调节采样时间、采样周期、切换样品瓶,准确、可靠、方便地采集水样。 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.
