Intelligent street lamp

Jun 04, 2019

Basic meaning

Realize remote centralized control and management of street lamps, with functions such as automatic adjustment of brightness according to vehicle flow, remote lighting control, active alarm of failure, anti-theft of lamps and cables, remote meter reading, etc., which can greatly save power resources, improve the level of public lighting management, and save maintenance costs.

Current situation of the development of

In China, the government street lamp management department has put on the agenda how to optimize the street lamp management system, effectively control energy consumption and reduce maintenance and management costs, as an important part of the construction.

In foreign countries, the public lighting management system has been aware of many shortcomings, began to upgrade.In London, the government has planned to invest 3.25 million pounds to replace 14,000 "smart street lights", which will allow maintenance staff to see if they need to be repaired or replaced, control the brightness of each street light and improve energy efficiency.

The implementation of the known cases abroad including Britain with the control of Westminster street lighting system, Germany's using mobile phones for street lamp lighting technology, the United States based on WIFI to control street lamp management technology, main domestic software applications, Chinese academy of sciences, guangzhou institute of technology in the electric power carrier communication technology and wireless communication system to control street lamp management.

On October 27, 2015, the first batch of 15 "smart street lamp" poles in the city was unveiled on dagu road in Shanghai, which has eight functions including lighting, charging of electric vehicles, one-button calling and wireless WIFI [1].

The implementation of significance

After the implementation of smart street lamps, it will not only exert a profound influence on the society, but also directly generate considerable economic benefits:

• strengthen the information construction of public lighting management, improve emergency dispatch and scientific decision-making capacity.

• reduce traffic accidents and public security incidents caused by lighting failures.

• save energy consumption of urban public lighting, build low-carbon and environment-friendly cities, and build livable areas.

• secondary energy saving through intelligent regulation to avoid waste and shorten the return on investment cycle.

• measure energy saving data, as a reference for power consumption data of power supply department, to prevent loss of leakage and theft of electricity.

The technology principle

The intelligent street lamp management system developed by the institute of software application technology of guangzhou Chinese academy of sciences is composed of software system and hardware equipment, divided into four layers: data acquisition layer, communication layer, application processing layer and interaction layer.Through the mutual cooperation of various layers, functions such as street lamp facility management, fault alarm, electricity monitoring, street lamp control and mobile terminal application are realized. In the later stage, intelligent functions such as vehicle flow monitoring and light sensing monitoring can be extended.

The software platform of smart street lamp management system is the core of smart street lamp and the central platform for monitoring, dispatching, operation and maintenance data management of street lamps.The system can quickly locate and manage street lamps by means of maps, including setting the scheduling strategy of single or a group of lamps, inquiring the state and history of street lamps, changing the state of street lamps in real time, providing various reports of street lamps and other functions.

The platform realizes the functions of five modules: monitoring management, data statistics, information query, parameter configuration and user management:

In the street lamp system, each concentrator and each node controller can be controlled.On the operation interface, the status of all concentrators and single lights can be displayed in real time, and control strategies such as single point control, group control and broadcast control can be realized for them.

The system provides GIS positioning to locate and display each street lamp on the map, and turn on and off the street lamp on the map, which greatly facilitates the management of street lamps.

It can automatically detect whether there are cars passing through the road section, and automatically adjust the lighting brightness according to the situation, which can realize the light regulation, longitude and latitude (sunset time) regulation, and the number of cars coming and the energy saving rate statistics, so as to achieve the energy saving effect.

When the street lamp fails or the cable is stolen, the lighting equipment failure system will be automatically reported to the business system immediately. The business system will be reminded by SMS warning, email warning and other ways according to the alarm information type.

Users don't need to go to the site to understand the street lamp electricity consumption, power and power factors, including real-time data query and historical data query, and can add, modify and delete electricity meters in the system;

By operating the client software on the computer, mobile phone, pad and other client terminals, users can conduct mobile management of lighting fixtures.The mobile control terminal has the functions of single lamp control and fault location, which is convenient for maintenance personnel to repair street lamps and conduct mobile management.
