基于无线模块NRF905的节能路灯控制系统设计

对基于无线模块NRF905的节能路灯控制系统的硬件电路与软件设计进行了详细论述。本系统设计能够根据环境的明暗变化、物体的动态移动来实现对LED节能路灯的定时开、关及故障报警等自动控制。其控制过程:总控制器和支路电路单片机之间通过NRF905(无线收发器)进行指令的接收与发送,总控电路实现对系统开关的定时,也可对单元电路进行单独定时,还可以根据光敏电阻对白天黑夜光线的感应来控制系统的开关,实现自动开、关灯。在支路电路中,用LM358集成运放来构成恒流源控制LED灯光的变化。通过光敏电阻对LED灯亮灭的感应检测,当支路电路发生故障灯灭时,发送相应的指令到主控制器来进行故障报警。当深夜人少时,利用红外传感器光电开关来判断行驶物体的范围来实现对LED开关状态的控制,以达到节能的目的。

Control system design of energy-saving street lights based on wireless module NRF905

This article based on the wireless the module NRF905 the energy-saving street light control system hardware circuit and software design are discussed in detail.The system is designed according to the brightness changes of the environment,the dynamic movement of the object to the automatic control of the timing the opening and closing and fault alarm LED energy saving lamps.By NRF905(wireless transceiver) in the control process: the total controller and unit circuit microcontroller instruction receiving and sending unit circuit system switch timing can also be a separate timing circuit unit can also be under the photoresistor night and day light sensor to control the switching of the system,automatic open,turn off the lights.In the cell circuit,the LM358 integrated op amp to form a constant current source to control the LED light changes.Photoresistor sensor detected the LED lights off when the unit circuit fault lamp is off,send the appropriate commands to the host controller to the fault alarm.When late at night is low,the use of infrared sensors,photoelectric switches to determine the driving range of objects to achieve the control of the LED switch status,to achieve energy saving.
