Street lamp energy-saving and managing system based on internet of things

Abstract

The invention belongs to the technical field of street lamp illumination, and in particular mainly relates to a street lamp energy-saving and managing system based on internet of things. The system mainly consists of a main monitoring center, a remote terminal unit (RTU) and wireless sensor nodes, wherein the wireless sensor node which is responsible for detecting and controlling single lamp street to operate and executing a lamping switching-on and switching-off operation by receiving an instruction sent by the RTU is arranged on each street lamp, the wireless sensor nodes are connected with the RTU through a GPRS (General Packet Radio Service) module, and the RTU arranged at a transformer workstation is respectively connected with the main monitoring center, a server and a display device through Internet. The street lamp energy-saving and managing system disclosed by the invention can realize illumination as required, high efficiency and energy saving and fine management, solves the problems generally existing in the current street lamp monitoring management system and has the advantages of wide application range and suitability for popularization.

Description

Technical field: [0001] The invention belongs to the technical field of street lamp lighting, and mainly relates to a street lamp energy saving and management system, in particular to a street lamp energy saving and management system based on the Internet of Things. Background technique: [0002] Street lighting is an indispensable part of urban infrastructure, and plays an irreplaceable role in the city's traffic safety, social security, people's life and city appearance. Therefore, ensuring the normal switching and lighting quality of street lamps is a major research topic for municipal construction. As the product of the combination of the three pillars of the information industry (computing, communication and sensors) in the 21st century, wireless sensor network (WSN) has attracted great attention from the world's major scientific and technological powers, and has formulated relevant policies and strategies at the national level. [0003] At present, the lighting contro...

Problems solved by technology

[0003] At present, the lighting control and management of most cities in the country still adopt the traditional mode. The switch of road street lights and urban night scene lighting is controlled by an independent clock for each box-type transformer or power distribution cabinet, which cannot achieve precise and unified control and management. In addition to partially realizing the monitoring of street lamp transformers, most of the street lamp facilities rely on the traditional management mode of manual inspection, resulting in the theft of street lamp cables, lamps and other urban street lamp facilities and serious man-made damage. The management goals of the scientific lighting mode of "dimming" are far from the management goals; especially when the current and voltage are instantaneously and violently changed during concentrated lighting, the huge impact on the special transformer and lamps is caused, which often causes damage to the equipment and greatly shortens the use of the equipment. lifespan, increasing the maintenance cost of urban lighting

[0004] The current mainstream control methods for urban lighting are: transformer-type centralized control, mostly one-way communication control, without a good feedback mechanism; although wireless single-lamp control can achieve energy-saving effects and fault feedback, its disadvantages are reflected in: (1) It cannot be real-time Control: Due to the single control method, it is impossible to classify and control lighting equipment of different lamp types, different areas, and different time periods, resulting in unreasonable resource allocation and a large amount of waste of electric energy

(2) Unable to switch lights in time: the current control method cannot automatically switch lights in bad weather (such as strong cloudy days)

Large-scale celebrations and political activities, leaders and group visits cannot be controlled in a timely and flexible manner, which affects the image of urban lighting

(3) Information cannot be fed back: various information of urban road lighting cannot be fed back to the management department

The management department cannot grasp the lighting situation in time

(4) Serious waste of electricity: the road lighting facilities controlled by manual switching lights need to be manually switched on and off every day, resulting in a long lighting time period; Self-adjustment, causing serious waste of power

(5) Failure to be found in time: When a street lamp fails, the information cannot be transmitted to the management department in time, relying on maintenance personnel to conduct regular inspections every day, in addition to increasing manpower, material and financial resources, the repair time will be delayed due to unknown failure conditions, affecting night lighting , causing great inconvenience to pedestrians and vehicles

(6) The light-on adjustment cycle is frequent: because the sunrise and sunset times are constantly changing every day, the staff need to often adjust the light switch time for each control point
