Description

Technical Field

[0001] The present invention relates to the technical field of street lamp lighting management, and in particular to a street lamp lighting management system based on wireless networking. Background Art

[0002] With the rapid development of urbanization, urban road infrastructure has been continuously expanded and improved. As a key component of urban road lighting, street lamps have grown in number exponentially and their coverage has become increasingly extensive. However, in the face of the complex and changing operating environment of modern cities and the growing demand for refined management, the traditional street lighting management model has exposed many thorny problems and is difficult to meet the concept of efficient, intelligent and energy-saving urban construction.

[0003] Under the traditional street lighting management structure, on the one hand, the monitoring of street lamp operating status is extremely weak, and municipal departments mostly rely on regular inspections or citizen reports to detect street lamp failures. This passive operation and maintenance method is extremely inefficient and has a significant time lag. It is difficult to predict potential failure risks in advance, resulting in blind allocation of maintenance resources and high operation and maintenance costs.

[0004] On the other hand, traditional street lighting completely ignores the profound impact of external environmental factors on the lighting effect of street lighting. The natural environment of different road sections varies greatly, and the lighting conditions are complex and changeable. For example, the road sections adjacent to open natural landscape areas such as parks and water systems have sufficient sunlight during the day, and strong moonlight and reflected light from the surrounding environment at night. The street lights can be dimmed appropriately to save electricity; while the street lights in the blocks with high-rise buildings and dense vegetation are blocked by buildings and tree branches and leaves, and the lighting range is limited, and the lighting effect is seriously damaged. However, the current system cannot adaptively adjust the brightness to compensate. At the same time, various interfering light sources are flooding the streets of the city. The continuous and stable strong light of advertising light boxes and the flashing strong light of vehicle headlights are mixed and interfere with the normal lighting output of street lights. Traditional street lights have no way to deal with this, which not only wastes electricity, but also causes poor lighting uniformity and comfort, reducing the citizens' night travel experience.

[0005] Furthermore, the tidal characteristics of vehicle and pedestrian traffic on urban roads are obvious, but traditional street lamps use a unified and fixed lighting mode, which cannot dynamically and flexibly adapt the brightness according to the real-time regional traffic. In the late night when there are few vehicles and pedestrians, the main roads and branch roads still maintain high-intensity lighting, and the phenomenon of power consumption is shocking; on the other hand, during the morning and evening rush hour commuting period, some key intersections and crowded commercial districts are difficult to meet the lighting requirements because the lighting brightness is not increased as needed, and traffic safety concerns are prominent. This static lighting control that ignores regional traffic differences is not conducive to energy saving and consumption reduction, and cannot guarantee ideal lighting service quality.

[0006] In order to solve the above defects, a technical solution is now provided. Summary of the invention

[0007] The purpose of the present invention is to provide a street lamp lighting management system based on wireless networking to solve the above-mentioned background problems.

[0008] The purpose of the present invention can be achieved through the following technical solution: a street lamp lighting management system based on wireless networking, including: a street lamp terminal and a street lamp lighting management platform.

[0009] The street lamp terminal includes a data acquisition module and a wireless communication module;

[0012] The street lamp lighting management platform includes a street lamp operation analysis module, an environmental impact analysis module, a regional flow analysis module, a brightness optimization control module and an execution terminal;

[0013] The street lamp operation analysis module is used to receive the working operation status parameter information of each street lamp corresponding to the target city road area, and perform working operation status determination and analysis processing of each street lamp corresponding to the target city road area, thereby generating a normal working operation signal and an abnormal working operation signal, and sending the abnormal working operation signal to the execution terminal for corresponding early warning operation;

[0014] The environmental impact analysis module is used to receive the external environmental impact parameter information corresponding to each street lamp in the target city area, and perform external environmental impact state determination and analysis processing corresponding to each street lamp in the target city area, thereby generating a light external environmental impact signal, a moderate external environmental impact signal and a heavy external environmental impact signal, and sending them all to the brightness optimization control module;

[0015] The regional flow analysis module is used to receive regional flow state parameter information corresponding to each street lamp in the target city area, and perform regional flow state determination and analysis processing corresponding to each street lamp in the target city road area, thereby generating a low regional flow signal, a medium regional flow signal and a high regional flow signal, and sending them to the brightness optimization control module;

[0016] The brightness optimization control module is used to receive external environment impact level type determination signals and regional traffic level determination signals, and integrate the two types of signals, thereby performing brightness control processing on each street lamp corresponding to the target city road area, and based on the brightness control parameters of each street lamp corresponding to the target city road area, performing brightness control operations on each street lamp corresponding to the target city road area through the execution terminal.

When the working operation coefficient is greater than the preset comparison threshold Yu, a normal working operation signal is generated. When the working operation coefficient is less than or equal to the preset comparison threshold Yu, an abnormal working operation signal is generated.

[0020] Furthermore, the specific solution process of the operating parameter deviation is as follows:
