LED lighting intelligent energy-saving monitoring system analysis
Urban street lighting is an indispensable public facility in people's daily lives. It is understood that the current power consumption of street lighting in China accounts for about 15% of the total electricity consumption. In the face of the tight supply situation, manual control and street lamp inspection have become an indispensable reality, and it is also a costly manpower and material resources. work. The existing traditional power-saving measures are only realized by turning off the lights at night, adjusting the switching time of the street lights, and turning off the landscape lighting when the electricity is tight. The method is simple and has little effect. On the road of the current LED street lights in the country, it is necessary to explore its own LED control system in combination with the characteristics of LED street lights. It is understood that the current market application of LED drive power management, LED lighting intelligent energy-saving monitoring solutions can be described as rare. Secondary energy-saving monitoring system with obvious advantages For the implementation of intelligent control management for street lamps, tunnel lights, square lamps, industrial lighting, etc., it will save more than 80% of manual inspection costs, so there is a strong market demand in the LED industry. First, energy saving and saving money. Take the 150W solution LED street lamp as an example; the pole spacing: 30m/pole, double-sided symmetrical lighting, 66 street lights per kilometer; dimming time per day: Regarding the energy-saving effect of the system, in order to be intuitive, the Maoshuo R&D Department calculated an account for the reporter of the “Ten Cities and Wanhao Referenceâ€: Increasing input cost per kilometer (batch): 66ç›Ã—90 yuan (power carrier module, concentrator)=5940 yuan; 10 km increase input cost (batch): 660 ç› Ã— 90 yuan (power carrier module, concentrator) = 59,400 yuan; Annual maintenance service fee per year: 50 yuan; Electricity savings per kilometer per year: 66ç›Ã—0.31×360 days=7467.9 yuan; 10 kilometers per year to save electricity costs: 7467.9 yuan × 10 kilometers = 74679 yuan. Second, the fast maintenance guarantee mechanism service can be implemented. Because the LED street lamp fault can be diagnosed remotely and quickly, based on the response of local service personnel, the average maintenance time control MTTR is less than 8H, and the municipal street lamp management department actually feels that the LED street lamp works normally every night. The third is to protect users' early investment. The existing system, after adding a power carrier module to the power supply, can be directly upgraded to an intelligent street light control system to avoid repeated investment. And the system adapts to the future energy-saving renovation and upgrading of the street lamp management department, such as the installation of LED street lights, etc., can directly realize the remote control dimming function to avoid secondary transformation. Fourth, the use of DALI protocol communication technology to achieve energy, environmental protection, multi-functional, high reliability and intelligent management. The solution product is designed around the goal of energy saving, environmental protection, multi-function, high reliability and intelligent management. It increases the development of lamp work intelligent control function based on DALI protocol, and innovatively adopts DALI protocol communication technology in traditional power supply through independent communication. The line, remote monitoring of each LED street light, to achieve intelligent management of LED street light switch, dimming, brightness feedback, status inquiry, fault alarm, group control, etc., to achieve further power saving and improve the service life of LED lights purpose. From the lighting usage time, the power consumption of the intelligent control LED system is about 3/4 or less of the power consumption of the non-intelligent LED.
