摘要
模拟路灯节能控制系统基于PWM脉宽调制技术,采用STC12C5A60S2完成对模拟路灯系统的控制。既能通过键盘设定系统时间、控制支路和独立控制单只路灯开关灯时间,又能自动检测环境光亮度控制开关灯,并可以自动检测交通状况自动调节路灯亮度。采用恒流源、PWM脉宽调制和故障检测电路,对路灯进行功率调控和故障判断,从而实现对路灯的节能控制。
An analog road lighting power-saving control cystem is based on （PWM） pulse width modulation technology, using STC12CSA60S2 to complete the simulation of the system control. Through the keyboard, we can set the system time, and control the lamp switch time of single luminaire independently. At the same time, we also can automatically detect the ambient light intensity to control switch lights and automatically control the traffic lights to make it adjust the brightness. Using constant-current power supply, PWM pulse width modulation and fault detection circuit, we can carry out the lamp power control, fault diagnose and achieve power-saving control of the road lighting.
