摘要
液位的平衡控制是锅炉安全运行的重要条件,介绍了以STC12C5A16AD单片机为核心的电接点液位控制系统。系统充分考虑到电极容易电解损坏的影响,采用了交变电压作为系统的检测信号,利用单片机的硬件和软件资源,实现了对容器液位的数值显示、模拟量输出、报警输出、RS-485输出、控制液位极限等功能。
The balance control of the liquid level is the important condition for safe operation of the boiler. In this paper, an electric contact liquid level control system by using STA12C5A16AD is intro- duced. By fully considering the influence of easily electrolytic damage of electrode, the alternating voltage is used as the system detection signal. With the use of single-chip hardware and software re- sources, it realizes the functions as flows: the numerical display of the level of a container, analog output, RS-485 output, liquid level limit control and so on.
