本系统用一台18位字长微型计算机控制流动纯水的电导值及溶氧量的临测分析。程序用BASIC语言编写。接口电路简单。一次仪表安装在现场取样点。仪表的采样、量程开关的转换、采样的速度等均由计算机控制。监测结果显示在黑白电视屏幕上,当需要保存数据时可启动打印机打出结果。当水质不合规格时,报警器自动报警。报警点的上下限,可以方便地改动。本系统一旦投入运行不需要人工干预,自动连续工作,稳定可靠。
The system uses an 18-bit word microcomputer to control the flow of pure water conductivity and dissolved oxygen in the provisional analysis. The program is written in BASIC. Interface circuit is simple. A meter installed in the spot sampling point. Instrument sampling, range switch switching, sampling speed, etc. are controlled by a computer. Monitoring results show that in black and white TV screen, when the need to save data can start the printer to print the results. When the water quality substandard, the alarm alarm. Alarm points of the upper and lower limits, you can easily change. Once the system is put into operation without human intervention, automatic continuous work, stable and reliable.
