Applicable places for intelligent lighting-street lights
A smart street light battle has now started vigorously. Before, Huawei and ZTE rushed to launch IoT control and processing solutions for smart street lights, and later LED lighting manufacturers joined leading IoT companies to compete for the market. According to reports, my country has the largest street lighting market in the Asia-Pacific region, and more than 35 million street lamps need to be transformed.
During the "13th Five-Year Plan" period, my country's plan is to build smart infrastructure, strengthen the development of information and communication skills to create smart cities and strengthen sustainable development capabilities. With the release of my country's "Thirteenth Five-Year Plan" plan, smart cities have become a key buzzword. As one of the good imports of the smart city, the smart street lamp market has also become a battleground for the military.
Why do you need smart lighting?
Lighting has always been a major consumer of urban electricity. It is a question that needs to be dealt with if An’an completes energy conservation and environmental protection on the premise of ensuring lighting needs. Now more and more cities choose LED to replace traditional lamps and lanterns, hoping to solve this problem, but with the large-scale expansion of cities, the lamps and lanterns are also increasing, which cannot be solved fundamentally.
The traditional lighting system is that people adjust the light through the switch, while the intelligent system is that the user gives instructions according to the terminal module, transmits the signal to the control center software through electronic induction, adjusts the voltage and current amplitude of the circuit with the help of the controller, and then completes the remote control. Control of single-light or multi-light switch, dimming, monitoring, etc.
The LED supports the dimmable function, and the intelligent lighting control system can adjust and control the lamps according to the time period, weather or other needs, and can realize the single-lamp control and multi-lamp control of the lamps to further save energy. According to the query data, plus the intelligent control system LED street lights can save 10%~20% more energy than the original LED energy-saving technology.
The connection between street lights and monitoring
Street lights are a wide-ranging infrastructure in urban life. It is understood that on the backbone roads, there is a street light every 20-30 meters. Such a high-density coverage rate can be fully utilized to form a natural urban fine coordinate network. At the same time, in the process of video surveillance point cover, foundation construction is very important.
For example, the laying of the pipeline network for foundation construction, including the laying of optical cables and cables, should be included in the field of consistent planning at the beginning of urban infrastructure construction planning. At the same time, in terms of the installation of road lights, from the perspective of cost saving and maximization of functions, street light poles are not only used to erect street lights, but can also become the carrier of monitoring probe points or other information collection equipment.
Actively promote smart street lights in China
In the last year, the street lights on many road sections have undergone "big changes". More than 10,000 street lights have been renovated, and the original high-pressure sodium lights have been gradually replaced by LED lights. At the same time, in order to save energy, save electricity and facilitate management, these street lamps are all equipped with an intelligent single-lamp control system. In these street lamps, the signal of each lamp is encoded, and the information collection and control chip is installed. Facing the computer, the staff can know the lighting status of the street lights, and can also control the street lights from a long distance, adjust their switches, power, etc. If the street lights are damaged or other conditions, the system will actively call the police, and the staff will contact the maintenance personnel in time after learning the fault information.
Foreign countries are at the forefront of smart street light applications
Foreign countries have always been the forerunners of LED street lights. In a few years in a foreign city, more than 160,000 lamps have been replaced with LEDs, and it is reported that it saves 63.6% of energy, equivalent to 8.8 million US dollars, and prevents 47,583 metric tons of carbon dioxide from entering the atmosphere. These smart streetlights only provide light at night, and with Ericsson's small cell technology, these streetlights can become a link during the day, providing residents with seamless 4G LTE services. The built-in networking equipment on these poles helps spread the signal load in an area. These small cells can be turned into a small cell tower, extending the range and strength of Internet connections throughout the city.
In the future evolution of smart street lights, in addition to basic lighting, energy saving and various intelligent control, in the future, it will no longer be a street light pole in the traditional sense, but will evolve to the collection end of the urban IoT sensor network. , the open carrier of outdoor convenience measures, such as the establishment of WIFI, 4G and other equipment, has become an important part of smart city construction data collection and monitoring. In the future, the city cloud big data interconnection channel based on "smart street lights" can also realize the "intelligence" of urban management, transportation, sanitation, advertising and Internet of Vehicles, etc., and then build a three-dimensional information and security network for smart cities.
