LED tunnel light intelligent control system
[Source: Gaogong LED's "LED Good Products" magazine April issue (P78)]
In recent years, due to the rapid development of semiconductor materials technology and the continuous improvement of social energy conservation and emission reduction requirements, LED lighting applications are gradually becoming popular. With the development of urban economy and scale, various types of roads are getting longer and longer, the number of motor vehicles is increasing rapidly, and the total amount and volatility of traffic flow are also increasing. The quality of road lighting directly affects traffic safety and urban development.
How to improve the quality of road lighting, reduce lighting energy consumption, and achieve a green development model has become a key issue in urban lighting.
At present, the primary task of road lighting is to provide safe and comfortable lighting brightness on the basis of saving public energy, to reduce traffic accidents and improve transportation efficiency.
Due to the limitations of domestic infrastructure conditions, domestic roads are usually illuminated by high-pressure sodium lamps. The power consumption is large, the color rendering index is low, and the grid has a large impact. The communication link between the lamps is generally lacking. A single control of the entire road, unable to control and monitor each lamp.
In view of the problems of the above lighting systems, intelligent LED lighting systems have emerged.
This paper combines the LED road lighting engineering examples, focusing on the LED tunnel light intelligent control system, which can not only adjust the LED illumination according to the site environment, but also realize the secondary energy saving of the lighting, further enhance the advantages of energy saving and environmental protection, and realize the LED tunnel light. The intelligent management and anti-theft detection enhance the intelligent level of the city, and fundamentally save the expenses of electricity expenses, lighting management fees, maintenance fees, etc., and promote the achievement of energy saving and emission reduction targets.
Advantages of LED Tunnel Light Intelligent Control System
The intelligent control system of LED tunnel light fully considers the actual situation of tunnel lighting, and adopts ARM control technology to dynamically and intelligently manage the illumination of LED tunnel lights.
Because the LED tunnel light has the characteristics of extremely fast transient response that other street lamps do not have, it is easy to realize the pulse width modulation and demodulation (PWM) adjustment using K-level Hertz, which adjusts the overall brightness of the lamp. There is no flicker when working at such a high frequency.
Through the luminaire setting, the tunnel light can maintain a strong illuminance during busy hours, and automatically dim the light when the vehicle is sparse in the middle of the night, so that the tunnel light maintains lower illumination.
Through the internal programmer, according to the prosperous degree of different city tunnels, lighting conditions, traffic flow conditions, the illuminance level is mandatory, the time-to-length ratio control of the intensity and intensity is set, and the program is executed periodically to realize the tunnel lighting personality. The treatment is better to meet the traffic safety and energy saving needs.
LED tunnel light intelligent control system requirements
With the continuous development of social civilization, the construction of highways has been overwhelming, and the management workload of the road lighting management department has also increased. It is difficult to find and repair faulty street lights in time. It is difficult to obtain the on-line inspection lights of the maintenance vehicles. Remote real-time monitoring has become a big helper for LED tunnel light management. It can pass the voltage and current of LED tunnel lights. The collection and analysis of parameters such as power, temperature, and communication status determine whether it is in a normal working state, and automatically handle abnormalities or automatically self-protect in time to gain time for the maintenance of engineering personnel.
Moreover, the tunnel lights are usually installed in places where there are few people in the suburbs. The lines are relatively long, and the theft of cables and LED lamps may occur. The intelligent control system of LED tunnel lights allows managers to quickly and accurately find out which specific location of the tunnel has occurred. The thief has won time for police officers to organize alarms and organize personnel to stop theft.
Technical scheme of LED tunnel light intelligent control system
1. LED tunnel light intelligent control system system frame diagram shown in Figure 1: LED tunnel light intelligent control system is mainly composed of three parts, namely the monitoring software of the upper machine end, the centralized controller of the control room end, the node controller of the lamp end .
2. The node controller frame diagram is shown in Figure 2. The control node consists of power supply, communication module, data processing ARM and dimming module. The control node needs to be installed on each LED tunnel light. When the system needs to control the LED tunnel luminaire, the communication module is responsible for receiving the upper layer command and handing it over to the ARM for control of the LED tunnel light; when the LED tunnel luminaire actively uploads information such as voltage and current fault, the information is sent by the ARM. The signal transmission module is then submitted by the signal transmission module to the centralized controller.
