Intelligent street lamp control system

Abstract

The invention discloses an intelligent street lamp control system. The intelligent street lamp control system includes street lamp control terminals, street lamp monitoring sub-stations and a street lamp management center; the street lamp control terminals acquire the voltage, current and power information of street lamp nodes and upload the data to the street lamp monitoring sub-stations; the street lamp control terminals receive commands issued from the street lamp monitoring sub-stations and execute operation so as to realize switching control and brightness adjustment of street lamps; the street lamp control terminals analyze and process received data packets, and send and receive data through radio frequency transmission modules; and the street lamp monitoring sub-stations maintain the node information of all street lamp control terminals on roads where the street lamp monitoring sub-stations are located, and transmit corresponding data to the street lamp management center. According to the intelligent street lamp control system of the invention, a GPRS public wireless communication technology and short-distance wireless communication technology-combined scheme is adopted, and the advantages of the GPRS public wireless communication technology and the short-distance wireless communication technology can be combined, and therefore, the problem of high cost can be solved, the complexity of the system is reduced, and the intelligent street lamp control system is practical, is convenient to manage, assist in saving energy and can realize intelligent control.

Description

technical field [0001] The invention relates to the technical field of urban road lighting, in particular to an intelligent street lamp control system. Background technique [0002] As the public infrastructure of urban lighting, street lights are not only an important part of urban construction but also inseparable from people's daily life. They play an inestimable role in the city's social security, traffic safety and city appearance. At the same time, whether the level of street lamp management and control is advanced or not directly reflects the level of urban modernization and civilization. With the development of wireless communication technology, the highly automated and highly reliable street lamp monitoring system has become an important symbol of building a modern metropolis. [0003] In recent years, with the development of economy and large-scale population growth, energy shortage and environmental pollution have become increasingly serious, which have attracted...

Problems solved by technology

Urban lighting is an important part of my country's lighting power consumption, and its energy consumption has been paid more and more attention by the country. With the development of wireless communication and information automation technology, the traditional street lamp control system model has gradually revealed its drawbacks. Not only the power utilization The efficiency is low, resulting in an extreme waste of energy, and the management method is outdated, which increases the trouble of manual inspection and maintenance

[0004] (1) The lighting fixtures are backward

[0005] Traditional urban lighting fixtures have the disadvantages of high energy consumption, low luminous efficiency and short service life. For example, periodic switching of lights will greatly reduce the service life of lamps, which not only causes waste of electric energy, but also frequently replaces lamps and lanterns. Increased material and labor costs

More importantly, traditional street lighting fixtures cannot adjust the light intensity value

The switch time of urban street lighting is generally determined according to the time of sunset and sunrise, and the switch time is different in winter and summer. If we take 12 hours of work as an example, the brightness value can be adjusted according to the actual operating conditions of the road. For example, the traffic flow and the flow of people on the road from 6:00 pm to 10:00 pm are normal, and the brightness is set to a constant maximum value, but after 10:00 pm, the traffic flow and the flow of people are significantly reduced. Therefore, it is a development trend of urban street lighting to realize the adjustment of brightness value.

[0006] (2) The management method is not intelligent enough

Compared with the manual control method, the efficiency is obviously improved, but in special circumstances such as rainy days, it may be necessary to re-modify the switching time of the street lamps. Since centralized control cannot be realized, it adds a lot of trouble to the staff

[0010] ②Low management and maintenance efficiency and high cost

[0011] Since the street light nodes work outdoors, they will inevitably be disturbed by the external natural environment. Whether it is a lamp or a transmission cable, when there is a failure, it will cause interruption of the communication line, and even cause all street lights in a large area to be uncontrollable.

The traditional street lamp inspection follows the method of "patching the line during the day and inspecting the lights at night", which greatly increases the work intensity of the inspectors, and does not know in advance which location the street lamp is faulty. The efficiency is extremely low, and it is difficult to meet the needs of the city. modern needs

[0012] ③Unable to achieve independent control of street lights

In the existing technology, the intelligent street lamp control system generally requires wiring, building a computer room, installing a server, and connecting an external current transformer. The cost is high and the stability is poor.

The overall distance of municipal street lights is long, and it is impossible to remotely monitor the operation status of each street light

The monitoring and maintenance of the original street lamps are not in place, and the damaged street lamps cannot be repaired, which affects road safety

The decorative lighting of street lights and park lighting can be turned off in the middle of the night, but it is uncontrollable and causes waste

The anti-theft problem of street lamp cables and transformers is difficult to prevent and control. After the theft cannot be found in time, some street lamps cannot operate normally, resulting in complaints from citizens

Fault supervision can only be done manually, and it is difficult to guarantee the lamp power, which is very difficult

In the pursuit of beautification and lighting, the power of street lamps is too high to cause the specified power density to exceed the standard
