The development potential of LED street light intelligent control technology is huge

1. From the perspective of standardization, the specifications of lamps produced by each LED street lamp manufacturer are different, and the specifications of intelligent control equipment are also different. If intelligent equipment manufacturers can formulate the control range and interface standards for lamps, lamp manufacturers can also according to intelligent equipment. The interface standard reserves the control interface for its own lamps. In this way, the selection space and the freedom of use of the intelligent system will be improved, which will bring convenience to the promotion. 2. Street lights are usually managed by the government-designated department. If the management department installs intelligent control systems from many different manufacturers and uses monitoring center software from different manufacturers, the daily management and maintenance will be quite cumbersome. If the industry can make some standards specifically for the intelligent control of LED street lights, according to some common operations, such as dimming, detection, setting timed dimming time periods, etc., reserve a unified communication interface on the centralized controller, so that the centralized control There is a fixed communication protocol between the controller and the monitoring center software, which is similar to the Modbus protocol often used in industrial control. In the monitoring center, the software design of the monitoring center can be completed according to the communication interfaces given by different control equipment manufacturers, and all centralized controllers can be managed uniformly, which is of great significance to the daily maintenance and management of street lamps. Moreover, the development trend of the city in the future is unified management. As part of the city, street lights will be included in the management scope together with other public facilities such as water, electricity, security, etc. If there is no unified standard, unified management will be difficult to achieve. 3. This method of dimming according to ambient light has also been applied in the past road lighting, but generally, a light-sensing device is installed on each lamp. There is no need for communication between the lamp and the lamp, and only automatic adjustment is required according to the light-sensing device. Self-luminous output. This method is difficult to achieve the consistency of dimming, and is greatly affected by dust and so on. However, the light control method does have its own advantages. For example, in the case of sudden changes in weather conditions, the brightness can be adjusted in time, which plays a very good emergency role. Therefore, in the future, it can be considered to install light-sensing devices in some specific places. These light-sensing devices communicate with the centralized controller and report the collected ambient light value to the centralized controller. Set the program to moderately change the output brightness of the LED street light. 4. In addition, cable anti-theft has always been a major problem in road lighting maintenance. Although some of the existing intelligent control systems can realize the anti-theft alarm when the lights are on, they cannot realize the cable anti-theft function when the street lights are not powered on. Therefore, in the future intelligent control system, the all-weather anti-theft function of the cable should be integrated according to the experience of the previous special cable anti-theft system.
