[0031] Specifically, the power module 2 converts AC power into voltage and current suitable for the street light controller, including the PN8143T power chip U1, which is connected to the WL2852K33 linear regulator IC1 and the linear regulator IC4 and the SY8113 buck chip FR1 through the EE19-41 high-frequency transformer T1, and the power chip U1 is connected to the EL816S1 optocoupler U3, and the power chip U1 is equipped with the 7533 linear regulator IC13. When the power fluctuates or an abnormal condition occurs, the power module 2 provides overload protection, overvoltage protection and overcurrent protection to ensure that the street light controller is not affected. The PN8143T power chip U1 has low power consumption, which reduces the overall energy consumption of the system and improves energy utilization.

[0032] In depth, the 4G communication module 5 establishes a communication link between the concentrator and the main station, including the wireless communication module U1A of the EC200S-CN model, and the wireless communication module U1A is equipped with a SIM card IC2. Through the AT command, the 4G communication module 5 initiates a connection and releases the occupation of the CPU. If no response is received within the preset time, the connection is automatically disconnected. Once the 4G communication module 5 establishes a connection, functions such as online data reading, status information acquisition, and alarm information reception can be realized. At the same time, the operating status and brightness adjustment of the street lamps can be remotely monitored, and remote control can be realized, such as remote control switch, brightness adjustment, etc.

[0033] Furthermore, the metering module 7 includes a metering chip IC5 of the V9240 model, which provides reliability and accuracy for high-precision measurement data, and collects the power usage of the street light controller in real time, including key data such as power consumption and power.

[0039] Preferably, the light sensing module 91 includes a light intensity sensor IC12 of model BH1750FVI, which uses a photoresistor or other photosensor to sense the light intensity in the environment and converts it into an electrical signal, thereby monitoring the lighting environment around the street lamp. The adjustment sensitivity and trigger threshold of the light sensing module 91 can be set according to actual needs to adapt to the needs of different environments.

[0040] In summary, the principle of this embodiment is: using the 4G communication module 5 to remotely monitor the street light controller, the street light controller has a built-in dimming module 9 and a light sensing module 91, which can sense the surrounding environment in real time and provide feedback to adjust the street light intensity.
