设计了一个路灯自动控制系统,具有时控、光控相结合的路灯开关控制功能;以及路灯故障检测并显示故障路灯编号的功能。采用STC89C51单片机作为核心控制部件;利用时钟芯片DS1302对路灯进行时控开关灯控制;由光敏器件完成环境光照度的采集与路灯故障检测,从而实现光控开关灯与故障路灯的编号显示。本系统可以通过RS-232标准通信端口与路灯控制室的上位机进行通信。 A street lamp automatic control system is designed. It has the functions of street lamp switch controlled by time control and light control, as well as the function of street lamp fault detection and fault lamp number display. Using STC89C51 as the core control unit; using the clock chip DS1302 on the street lamp time-controlled switching light control; by the light-sensitive devices to complete the collection of ambient light and street light fault detection, in order to achieve light-controlled switch lights and fault lights show the number. The system can communicate with the host computer of street light control room through RS-232 standard communication port.
