本作品是具有自动化程度高、运行可靠、使用维护方便的照明控制系统,为城市路灯现代化提供了一些参考方案。系统采用STC单片机为核心的最小系统板,设计了模拟路灯控制系统。控制系统采用定时器设定时钟功能,设定、显示开关灯时间;用传感器检测物体的定位路灯单元控制系统采用恒流源供电,具有输出功率调整功能,并能定时调整功率。阐述了基于单片机模拟路灯控制系统实现的设计思想、方法及过程。该模拟控制系统,能有效的节约能源,减少照灯具的损耗。ABSTRACT
This work has a high degree of automation, reliable operation, and easy maintenance of lighting control system; provide some references for the modernization of city lights. STC single-chip at the core of the system of minimum system board, design a simulated Street lamp control system. Control system uses a timer to set the clock function, settings, display switch lamp time; based on 555 as the core of the infrared sensor to detect the orientation of objects. Street lamp control system uses a constant current power source, with output power adjustment features, and adjust the power can be scheduled. Elaborate Street lamp control system based on single-chip computer to realize the design, methods and processes.
In the daytime mode, can also according to the environment of light and shade change control street lamp of opening and closing street lamp, in night mode according to the road traffic situation to be automatic open to turn off the lights. When the lamp fails is not bright, capable of detecting and alarm by sound and light system, fault lamp number displayed on the monitor. Homemade LED lamp constant current power supply in the unit controller, in most cases, system stability, and low power consumption characteristics.
The simulation control system can effectively save energy, reduce the loss as the lamps. With STC89C51RC as the core, using time clock control of LED lights switch, motion signals through the three infrared sensor modules by 555 TTL low level input single-chip, and judging by three infrared input object is running, control of LED lights switch. And complete the four functions: time setting function, environmental value judgments, the independent control functions, traffic control functions.
Keywords: STC89C51、single-ch
