Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and particularly to a communication gateway integrated with a street lamp controller. Background Art

[0002] In the era of the increasingly prosperous modern cities, the construction of smart cities is also rapidly popularizing, and the smart street lamp project is an important part of it. As the nerve endings of the new urban infrastructure, smart street lamps are undergoing a paradigm shift from "single-function type" to "intelligent service type" in the evolution of smart cities. Traditional street lamp systems rely on mechanical control methods such as timers and photosensitive switches, and generally have three major pain points: First, the energy consumption efficiency is low, and the average energy saving rate is less than 20%; Second, the operation and maintenance response is lagging, and the discovery of faults depends on manual inspections; Third, the function expansion is limited, and it cannot be connected to the urban Internet of Things platform. The construction of modern smart cities requires that the street lamp system must have four core capabilities: remote dynamic dimming (±5% accuracy), minute-level fault location, multi-dimensional energy consumption analysis, and real-time data interaction with urban perception terminals such as traffic signal lights and environmental monitoring stations. As the nerve center of the smart street lamp system, the communication gateway undertakes three core functions: First, it aggregates the data of street lamp controllers through short-range wireless protocols such as Wisun / LoRa / ZigBee; Second, it performs edge computing to achieve local decision-making, such as emergency event response; Third, it establishes a secure connection with the urban-level management platform through wide-area networks such as 4G / 5G / NB-IoT. The traditional stand-alone gateway architecture has significant defects: it requires separate planning of the installation space and configuration of a dedicated box, additional laying of power supply lines, and repeated wiring during migration and maintenance, which fundamentally conflicts with the design concept of "multiple functions on one pole, integration of multiple poles" of smart street lamps.

[0003] The deployment of traditional communication gateways relies on specific infrastructure, such as newly built utility poles, leased rooftop platforms or communication towers, and additional protective devices, such as dust and waterproof enclosures, are required to meet outdoor environmental requirements. This kind of deployment has a strong dependence on the location selection, which not only increases the difficulty of site coordination, but also gives rise to the cost of supporting projects, significantly extending the project cycle. In addition, traditional communication gateways mostly adopt independent power supply lines, and an additional power wiring system needs to be planned, which not only increases the difficulty of construction coordination, such as pipeline laying approval and line cross-interference, but also introduces electrical safety hazards, such as the risk of line aging and illegal power connection. At the same time, the single power supply mode is difficult to adapt to diverse deployment scenarios, such as areas without mains power, restricting the flexibility of equipment location selection. As an independent functional unit, the traditional gateway is not system-level integrated with associated devices, such as street lamp controllers, resulting in the need to repeatedly develop structural components (such as fixed brackets, heat dissipation modules) and power supply structures. This design fragmentation not only increases the hardware development cost, but also causes low space utilization, affecting the overall system aesthetics and maintenance convenience. Therefore, there is an urgent need to propose a communication gateway integrated with a street lamp controller to solve the technical problems of how to achieve the integrated integration of the gateway and the street lamp controller, and realize the remote control and data collection of the street lamp controller through the gateway.
