Focus on LED applications to promote smart transportation development

The Symposium on Smart Energy LED Energy Saving and Emission Reduction Technology and Standards was sponsored by the Transportation Engineering Branch of China Highway Society, co-organized by Shanghai Sansi Electronic Engineering Co., Ltd., deputy director of the Energy Conservation Office of the Ministry of Communications, deputy director of the Highway Science Research Institute of the Ministry of Communications, and Dalian Road Tunnel of the Shanghai Construction and Communications Commission. Ten experts including the company secretary gave a speech at the conference and looked forward to the future development of LED highway applications. The 12th Five-Year Energy Saving and Emission Reduction Plan of the State Council puts forward new requirements for LED highway applications. The “12th Five-Year Energy Saving and Emission Reduction Comprehensive Work Plan” and the “12th Five-Year Control Greenhouse Gas Emission Work Plan” issued by the State Council have been submitted to the end of the 12th Five-Year Plan period. The national unit GDP energy consumption and carbon dioxide emissions decreased by 16 and 17. Compared with 2010, in the transportation industry, the proportion of road transportation to comprehensive transportation energy consumption is 39.5. It is imperative to promote green and low-carbon transportation. Since 2011, the Ministry of Transport has set up a special fund for energy conservation and emission reduction for transportation, which is used to award and subsidize the methods, encourage enterprises and institutions to achieve energy-saving and emission reduction application results, and has now launched 5 batches of 100 ministerial level. Energy conservation and emission reduction demonstration project. This fund focuses on institutional, management and technological innovations to drive the development of green transportation. In the field of transportation, how to more effectively use the energy-saving effect of LED lighting and display products, so that the heads of highway construction and design units in various provinces and cities agree and accept LEDs.
The transformation plan has also become a topic of discussion among many experts. Experts believe that LED road lighting and display need to provide multi-level, all-round energy-saving emission reduction programs in order to win market recognition. Strengthening the development of LED road application standards is imperative to strengthen the standardization of the LED industry, which has become a topic of common concern in the industry. The inconsistency of highway lighting systems is not conducive to ensuring the quality of LED road lighting products. It will bring many problems and problems to the procurement, installation, maintenance and service of products. In this regard, Jiang Haifeng, an associate researcher at the Highway Science Research Institute of the Ministry of Transport, explained in detail the standards of the "Highway LED Lighting" and the tracking test results of the LED lighting demonstration project of the three ministries, which pointed out a new direction for the development of the industry. The LED lighting demonstration project of the three ministries tunnel involves 15 road tunnel LED lighting demonstration projects, which spans 14 provinces and cities, and through strict experimental measurements, finally obtains higher pressure sodium lamps for LED lamps: average energy saving of 73.1, 72.6 and 61.4 during 24 hours during the day; Fine dimming is more than graded dimming: the average power saving of 48h is about 32.07. Over the years, Shanghai Sansi has completed more than 1,000 LED variable information sign projects in 28 provinces, municipalities and autonomous regions in China, providing 15,000 sets of equipment.
The energy-saving products developed in recent years have been successfully applied. Take the expressway project as an example: an energy-saving gantry-type variable information sign with an area of ​​1m10m and a point spacing of 31.25mm, saving energy up to 80, and saving A considerable amount of disposable cable purchases. The energy-saving high-pixel-density LED display developed by Sansi has light weight and no seams; unique grayscale processing, fine and flicker-free picture, high-speed picture without smear; distributed power supply is more energy efficient; dual backup signal path and power supply are more Reliable; touch, somatosensory intelligent control, realize group network synchronization control; carrier technology, instead of plug-in flat line transmission, P1.66, P2.0, P2.5 and P2.75 high pixel density screen have been applied The traffic monitoring center of highway operation management has been approved by users. Shanghai Sansi, which has become the industry benchmark, deeply feels that he is shouldering the burden and not scorning. He has taken a step forward in exploring the energy-saving potential of LED, and has played an exemplary role in energy-saving and emission reduction of LED traffic applications. At the same time, he participated in the promotion of LED industry. The formulation and implementation of standardization regulates the industry. At present, the intelligent control integrated system has been developed, and the intelligent lighting monitoring system demonstrated by the system laboratory is a testing ground. The prospect of LED highway application is as brilliant as the China Communications and Communications Information Center and Beijing Jiaoke Survey and Design Institute. In the speech, energy saving and emission reduction is an important national policy in China for a long time now. With the development of LED chip technology, light Continuous improvement,
The cost is gradually decreasing, the temperature rise and light decay problems are gradually solved, and LED lighting will be quickly promoted and applied. The various types of highway LED variable information signs are indispensable and irreplaceable important information release equipment in the traffic information development industry chain. With the continuous implementation of the "Highway Monitoring Technical Requirements", with the intelligent transportation and traffic informationization, The promotion of the service-oriented concept will surely usher in a better tomorrow. It is reported that the special seminar on energy saving and emission reduction technologies and standards for traffic engineering is the first time in China. This is of great significance for promoting the promotion and application of LED technology in China's traffic engineering and implementing energy conservation and emission reduction in the transportation industry.
