In contemporary society, urban lighting has become a business card and window to showcase the charm of a city, because

 urban lighting is not only a science, but also a culture and an art. Urban street lighting is a beautiful landscape of the city. 

With the continuous development of digital smart cities, urban street lighting is becoming intelligent .

In the management background, each street lamp or each group of street lamps can be remotely switched on or dimmed, 

and the voltage, current, power, switch status and other parameters of each street lamp can be remotely monitored in real time. 

All control and management work is completed through LoRa...

At present, the intelligent street light control solution adopts GPRS wireless communication technology and power line carrier 

communication technology, using computers and mobile phones to remotely and centrally manage road lighting, but this 

management technology has its shortcomings:

1. GPRS traffic charges are high and need to be paid continuously. The larger the city, the more street lights there are, and the 

higher the charges.

2. Power line carrier communication technology, due to its own technical limitations, still has poor signal quality and is susceptible

 to power line loss and interference. When the line is shut down for maintenance, data cannot be transmitted.

LoRa wireless remote management system composition

1. Front end: Front end LoRa wireless module; built into the lamp.

2. Gateway: Receive LoRa module information and forward it to the backend.

3. System background: Based on the street light network, the background combines the gateway, street lights and other components 

with the graphic information of the geographical location, and displays this information in the form of pictures and texts. It includes

basic operation functions, street light equipment status, single light control, group control, timing control, etc.

The principle of docking between street light controller and LoRa module: Through docking, the LoRa module conveys the on, off 

and dimming instructions to the street light controller to control the street light; it can also transmit the street light self-test status 

signal to the background, and the background can monitor the information of each street light.

In the management background, each street lamp or each group of street lamps can be remotely switched on or dimmed, and the

 voltage, current, power, switch status and other parameters of each street lamp can be remotely monitored in real time. All control

 and management work is completed through LoRa.

Smart street lights can effectively adjust the brightness of lights according to the flow of people and weather conditions. They can 

be in full-on mode, energy-saving mode, late-night mode, and single-lamp control. At the same time, they can monitor the status of 

the lamp to improve maintenance efficiency.
