基于霍尔传感器的全自动照明控制系统的设计

在分析比较各种开关的基础上,选择霍尔传感器开关设计了一套全自动照明控制系统.该系统通过房门的打开和闭合控制照明灯的亮灭,门每开一次,照明灯自动点亮或熄灭,门关闭则对照明灯不起作用.电路中用霍尔传感器将房门的开关动作信号转变为电信号,用CD4017计数/脉冲分配器接收该电信号,并将该电信号转变为控制信号来触发双向可控硅导通,进而控制房间照明灯的开关.设计了实际电路并进行了仿真实验.结果表明,该系统基本实现了对照明灯的控制功能,有比较明显的节能作用,制作简便,成本低廉,可广泛应用于公共场所洗手间的照明控制.

Design of Fully Automatic Lighting Control System Based on Hall Sensor

A fully automatic lighting control system with a Hall sensor was designed on the basis of the analysis of various kinds of switches. The system controlled the lighting and extinguishing of the lamps through the openning and closing of a door. The lamps were automatically turned on or extinguished whenever the door was opened. When the door was closed, the lamps did nothing. The opening and closing signals of the door were transformed into electric signals by the Hall sensor in the circuit. The electric signals were received by a CD4017 counting and pulse distributor in which the electric signals were transformed into the signals for triggering a two-way thyristor to control the lighting and extinguishing of the lamps. The actual circuit was designed and simulated. The simulation result showed that the system was able to control lamps basically and its energy-saving was remarkable. It was cheap, easy to make and could be widely used in public lavatories for controlling lamps.
