一种基于STM8控制的LED楼道灯设计

Design of an LED corridor lights based on STM8 control

楼道灯作为民用建筑常用设备,在楼道灯的设计中利用单片机可以增加其功能。为增加楼道灯的功能、增强其实用性,提出了一种雷达感应楼道灯的设计。首先在电路设计中,针对485通信电气干扰,利用光耦器等多种隔离器进行隔离;其次,利用温度系数B值法和均值滤波函数等方法,表现热敏电阻RT特性,实现模拟信号和数字信号间的转换。仿真结果表明:雷达感应楼道灯有较高的光效,同时其查询模式可以方便设备检修,提高设备维修效率。

Corridor lights are commonly used in residential buildings,and the use of microcontrollers in their design can enhance their functionality.To increase the functionality and practicality of corridor lights,a radar-sensing corridor light design is proposed.First,in the circuit design,various isolators,such as optocouplers,are used to isolate the 485-communication electrical interference.Second,the characteristics of the thermistor RT are realized using the temperature coefficient B value method and the mean filtering function,achieving analog-to-digital conversion.Simulation results show that the radar-sensing corridor light has a high luminous efficiency,and its query mode can facilitate equipment maintenance and improve equipment maintenance efficiency.
