The street lamp comprises lane signal lamps 7 and sidewalk signal lamps 8, wherein the number of the lane signal lamps 7 is one, and the number of the sidewalk signal lamps is two.
The street lamp communication module is a ZigBee communication module, the master control communication module is a ZigBee communication module, and the street lamp communication module and the master control communication module form a transmission network. The street lamp control chip is an STC89C52RC single-chip microcomputer, and the main control chip is an OK6410 development board.
The OK6410 development board and the main control communication module carry out serial communication through the serial port 2, and the baud rate is 9600. The COM port of the OK6410 development board, i.e., (J13) IO port, is connected to VCC, GND, RX, and TX of the main control communication module by pins of the led-out flat cables 1(VCC), 2(GND), 5(TX), and 6(RX), respectively.
