自动水满报警器设计

自动水满报警器是当今运用十分广泛的报警器产品,在人们的日常生活发挥着重要的作用。该电路设计方法很多,但功能都是唯一的:实现水满后自动报警。而工作原理、分析方法、电路调试等都因具体电路而异,所以电路工作原理分析、电路安装与调试处理技术犹为重要。本文从自动水满报警功能出发设计了一个功能较为完善的电路,利用PCB进行制作,并对电路工作原理和元件参数选择进行了系统的分析,根据工作原理和调试的结果,从所存在的一些问题着手,改变电路结构和元件参数,进而更准确地实现电路功能。

Design of Automatic Water Annunciator

Automatic water annunciator, used extensively nowadays, plays a very important role in fire engine department, company security, and in our daily life. There are many ways to design its electric circuit, but it has only one function that it alerts when water is full. However, working principles, analysis, and circuit test depend on the concrete electric circuit, making their technique important. We have designed a more perfect electric circuit based on the function of automatic water annunciator, and analyze systemically the working principle of electric circuit and selection of component parameter. According to the working principle and the results of adjustment, there are still some problems. We have solved the problems, and have changed the component parameter, and have made its electric circuit accurate.
