Power distribution cabinet-based energy management and optimal scheduling system for multifunctional intelligent lamp post

Abstract

The invention discloses a power distribution cabinet-based energy management and optimal scheduling system for multifunctional intelligent lamp poles. The system comprises a street lamp power distribution cabinet and a multi-pole collaborative energy-saving subsystem, wherein the multi-pole collaborative energy-saving subsystem comprises an intelligent gateway and a plurality of lamp poles; each lamp post is provided with an LED lamp, a constant current driver and an intelligent single lamp controller; a 5G base station is mounted on one lamp pole; the intelligent single lamp controller, the constant current driver and the LED lamp are connected in sequence; the intelligent gateway is installed in a street lamp power distribution cabinet, the signal input end of the intelligent gateway is connected with the 5G base station, and a plurality of signal output ends of the intelligent gateway are connected with the intelligent single lamp controllers on the lamp poles respectively. According to the system, the LED lamp can be subjected to time-phased dimming, so that more than 70% of energy can be saved for the lighting system, and the saved electric energy can be used for expanding other applications of the intelligent lamp post.

Description

technical field [0001] The invention relates to the field of multifunctional smart light poles, in particular to a power distribution cabinet-based energy management and optimal dispatching system for the multifunctional smart light poles. Background technique [0002] As a new type of urban information infrastructure including road lighting, video security monitoring, meteorological environmental monitoring, 5G mobile communication base stations, public information release and charging piles and other functional modules, multi-functional smart light poles are a breakthrough in the construction of smart cities. The "multi-purpose" smart light pole not only saves energy, but also reduces the occupied area of ​​urban land and promotes the efficient use of resources; as the information perception terminal of the smart city, it supports the full coverage of the urban Internet of Things. Since the multi-functional smart light pole is not only the physical carrier of the smart cit...

Problems solved by technology

[0003] First, because the power system of the existing street lights cannot meet the power demand of the multi-functional smart light poles, it is necessary to build and upgrade the power grid, but this process is extremely expensive and takes a long time

In addition, the current demonstration poles of multi-functional smart light poles cost tens of thousands or even hundreds of thousands of construction costs per pole, which is far beyond imagination, and the later operation mode is chaotic.

[0004] Second, the existing street lamps automatically realize power transmission in the dark and power-off at dawn through the light control box, which is relatively safe

However, smart light poles must run continuously 24 hours a day, and the hidden dangers of electric leakage and electric shock accidents caused by accelerated aging of power supply line equipment will increase significantly.

[0005] Third, the wiring of the multifunctional smart light pole is complex, and there are many weak current devices on board, which are easily damaged by lightning strikes

[0006] Therefore, for the multi-functional smart light pole, how to realize "no additional cabinets", "no change of mains power (such as mains transformer, power supply cable, pre-stage air switch, etc.)" and "no change of power distribution (including thick wires) "The low-cost deployment of ", and how to solve the problems of low operating safety and chaotic operation mode of multi-functional smart light poles have become urgent problems for practitioners in the same industry.
