Design of Wireless Remote Control System for Signal Lamp

信号灯红外无线遥控系统,通过接收红外光不同频率的信号,由PLC转化成对应的控制方法从而控制电路,最后通过接收电路的输出端与PLC输入端相连以完成控制功能。本文主要从信号灯无线遥控系统原理、发射系统设计、接收系统设计三方面进行阐述。最大限度的利用了PLC现代控制优势,充分发挥了信号灯的作用。

This paper designs a kind of semaphore wireless remote control system. By receiving infrared light signals of different frequencies, the PLC is transformed into the corresponding control method and control circuit. Finally, through the output end of the receiving circuit and PLC input connected to the control function has been completed. This article mainly from the signal light wireless remote control system principle, the launch system design, the receiving system design three aspects elaborated. The maximum use of the PLC modern control advantages, give full play to the role of the signal lights.
