摘要

楼道触摸式延时开关由延时开关电路、电源电路、报警电路和触发信号电路四个部分构成。装置中运用了555定时器、集成稳压管、窗口比较器等器件。当人触摸该装置电极时，灯泡立即发光；当人手离开电极之后，灯泡维持30秒左右发光，最后熄灭。同时该装置还有防触电装置，当电极片电压高于12V时,电路会产生报警信号，说明该电极以漏电。运用Protel 99SE软件绘制了单元电路以及总体电路图，借助Multisim 2001仿真软件对单元电路以及总体电路进行了仿真虚拟实验，达到了本次楼道触摸式延时开关设计的基本要求。

Abstract

The corridor touching type time-delay switch is made up of time-delay switch electric circuit, power circuit, alarm circuit and trigger pip electric circuit. The installment has utilized 555 timers, integrated voltage comparator, window comparator, and so on. When the human touches this equipment electrode, the light bulb shines immediately; after the manpower leaves the electrode, the light bulb maintains about 30 seconds to shine, finally extinguishes. Simultaneously this equipment also has against receives an electric shock the installment, when the electricity pole piece voltage is higher than 12V, the electric circuit can produce the alarm, explained that this electrode leaks. Software has drawn up the unit electric circuit as well as the overall circuit diagram using Protel 99SE, and has carried on the simulation hypothesized experiment with the aid of the Multisim 2001 simulation software to the unit electric circuit as well as the overall electric circuit. The function of the corridor touching type time-delay switch is achieved.

Keywords time-delay switch electric circuit, power circuit, alarm circuit, trigger pip electric circuit
