The traffic flow monitoring module is used to monitor the traffic flow situation. The traffic flow value is directly imported through the toll station data system. When the traffic flow monitoring module detects that the traffic flow is zero, the analog signal of the zero traffic flow is converted into After the digital signal is sent to the system control module through the Zigbee communication module, the traffic flow is zero signal, and the system control module sends the street light off control signal to the street lamp control module through the Zigbee communication module after receiving the traffic flow monitoring module. The control module activates the power switch of the street lamp to adjust the street lamp to the off state after receiving the street lamp shutdown control signal, and does not consider the monitoring situation of the illuminance monitoring module and the visibility monitoring module at this time.

When the traffic flow monitoring module detects that the traffic flow is not zero, it can be divided into the following two situations:

When the traffic flow monitoring module detects that the traffic flow is higher than the set value (traffic flow ≥ 20), the traffic flow monitoring module does not send a signal. At this time, when the illuminance meter monitors that the ambient brightness drops to the set value (80Lux in this embodiment) ), the ambient brightness signal is converted from an analog signal to a digital signal through the A/D converter and sends the ambient brightness signal to the single-chip microcomputer through the Zigbee communication module.

At the same time, when the illuminance meter monitors that the ambient brightness drops to the set value (80Lux in this embodiment), the ambient brightness signal is converted from an analog signal to a digital signal through the A/D converter and sent to the microcontroller through the Zigbee communication module.
