Description

Street lamp energy-saving control system based on pyroelectric infrared sensor

Technical Field

The utility model relates to a city lighting technology field, especially a street lamp energy-saving control system based on pyroelectric infrared sensor.

Background

With the rapid development of urban lighting construction, although the urban lighting system provides convenient life for people and creates urban livable environment, a large amount of consumed power resources cannot be ignored, and in order to relieve the contradiction between the two, in the development process of a smart city, a lighting information management system with lighting on demand and intelligent management is generated, so that the system plays an effective role in improving the lighting rate of the whole urban lighting, saving energy, improving the investment environment, reducing traffic accidents, guaranteeing personal safety, stabilizing social security and the like.

Urban road lighting is an important infrastructure of a city, along with the development of urban construction, the urban lighting construction focuses more and more on the image of the city, and the monitoring degree of urban street lamp lighting also becomes one of important marks of the city. It reflects the spiritual outlook of a modern city and is an image representative of a city. Plays an important role in city public security, city beautification, night traffic and city civilization construction, and provides important guarantee for the life and economic activities of urban people. The street lamp control operation is realized by controlling the power supply to the street lamp, the basic power supply loop of the street lamp illumination is the transformer, the power supply distribution cabinet, the cable to the lamp post and then to the street lamp on the lamp post, and the control mode is to control the on-off of the alternating current contactor in the power supply distribution cabinet to realize the control of the switch lamp.

The street lamp is used as a main component of city lighting engineering and plays a very important role at night. The street lamp not only provides the night traffic safety illumination, but also is a necessary facility for maintaining the night public security, and the level of urban modernization can be seen from the quality of the street lamp facility, so that the construction of the street lamp facility in all cities in the world is very important. With the great rise of energy price in recent years, the huge electricity expense of the street lamps also becomes a great burden for local governments, and the shortage of electricity and the backward illumination become bottlenecks which restrict the economic development. In recent years, the problem of lighting power saving is listed as another important power saving project besides power saving, which undoubtedly has very important significance for promoting the development of power-saving operation.

Urban street lighting is an indispensable public facility in people's daily life. The power consumption of street lamp illumination accounts for about 15% of the total power consumption, and various problems caused by power shortage can not be solved all over the country. In the face of the situation of power supply shortage, the street lamp patrol is a work which needs to consume a large amount of manpower for municipal departments, and various temporary emergency electricity-saving measures are widely adopted: the lamp is turned off at night intervals, the time of turning on and off the street lamps is adjusted, landscape lighting is turned off in the days with intense electricity consumption, and the like, when the electricity consumption peak passes, the measures can be restrained at a high position, and all the measures can be restarted when the next electricity consumption peak comes. The electricity-saving measures can relieve the power shortage and bring the waste of resources and the negative influence on the daily life of people. The best and effective method for relieving the power utilization shortage is to implement intelligent management on power utilization, reduce waste and make the best use of electricity at every degree.

For an intelligent street lamp system, it is important to be able to accurately judge whether a person passes through the street lamp system under dark conditions. The traditional switch street lamp and sound control street lamp system need to artificially control the switch or make the street lamp light by emitting certain sound. For a street lamp system controlled by a switch, when pedestrians cannot be turned off in time after the pedestrians pass, the street lamp system is turned on for a long time, and waste is generated; for a sound control system, when people are quiet at night, the street lamps need to be lightened through behaviors of coughing with loud voice, clapping hands, stomping feet and the like, noise is generated, and normal rest of surrounding people is influenced, so that the two methods are very inconvenient and easy to generate misoperation, and therefore the two street lamp control systems cannot effectively play a role and cannot realize intellectualization.

At present, most of traditional street lamp switches are controlled by time or manual work, which brings inconvenience in the actual management process. Due to the uncertainty of the external environment, the situation that when a street lamp is turned on at night, the day is not dark, or when the street lamp is turned on in the morning, the street lamp is still turned on and serious electric energy waste is caused can be frequently caused through time control. The sunshine time is short in winter, the street lamp is not turned on after the sunshine time is dark, and the street lamp is turned off after the street lamp is not turned on in the morning, so that the traveling of pedestrians and vehicles is influenced. The existing street lamp does not have the function of alarming when accumulated water is deep, namely, unattended places such as roads are prone to water damage, people on duty cannot be informed to remove dangerous situations in time when the accumulated water cannot be discharged in time, and a good real-time alarming effect cannot be achieved.
