Description

Technical Field

[0001] This utility model relates to the field of wireless communication technology, and in particular to a communication gateway for an integrated street light controller. Background Technology

[0002] In today's increasingly prosperous cities, the construction of smart cities is rapidly becoming widespread, and smart streetlights are a crucial component. As the nerve endings of new urban infrastructure, smart streetlights are undergoing a paradigm shift from "single-function" to "intelligent service" in the evolution of smart cities. Traditional streetlight systems rely on mechanical control methods such as timers and photosensitive switches, generally suffering from three major pain points: First, low energy efficiency, with an average energy saving rate of less than 20%; second, slow operation and maintenance response, with fault detection relying on manual inspections; and third, limited functional expansion, unable to connect to the city's Internet of Things (IoT) platform. Modern smart city construction requires streetlight systems to possess four core capabilities: remote dynamic dimming (±5% accuracy), minute-level fault location, multi-dimensional energy consumption analysis, and real-time data interaction with urban sensing terminals such as traffic lights and environmental monitoring stations. As the nerve center of a smart street light system, the communication gateway undertakes three core functions: First, it aggregates data from street light controllers via short-range wireless protocols such as Wisun / LoRa / ZigBee; second, it performs edge computing to achieve localized decision-making, such as emergency response; and third, it establishes a secure connection with the city-level management platform via wide-area networks such as 4G / 5G / NB-IoT. Traditional stand-alone gateway architectures have significant drawbacks: they require separate installation space and dedicated enclosures, additional power lines need to be laid, and rewiring is involved during relocation and maintenance. This fundamentally conflicts with the design concept of smart street lights—"one pole, multiple uses; multiple poles, one system"—often integrating into a single system.

[0003] The deployment of traditional communication gateways relies on specific infrastructure, such as newly built poles, leased rooftop platforms, or communication towers, and requires additional protective devices, such as dustproof and waterproof enclosures, to meet outdoor environmental requirements. This highly site-dependent deployment not only increases the difficulty of site coordination but also incurs additional engineering costs and significantly extends the project cycle. In addition, traditional communication gateways often use independent power supply lines, requiring additional planning of power cabling systems. This increases the difficulty of construction coordination, such as pipeline laying approvals and line cross-interference, and introduces electrical safety hazards, such as the risk of aging lines and illegal power connections. At the same time, a single power supply mode is difficult to adapt to diverse deployment scenarios, such as areas without mains power, limiting the flexibility of equipment site selection. As an independent functional unit, traditional gateways are not integrated with related equipment, such as street light controllers, at the system level, resulting in the need to repeatedly develop structural components (such as mounting brackets and heat dissipation modules) and power supply structures. This fragmented design not only increases hardware development costs but also results in low space utilization, affecting the overall system aesthetics and ease of maintenance. Therefore, there is an urgent need to propose a communication gateway that integrates street light controllers, and to solve the technical problem of how to achieve the integrated integration of the gateway and the street light controller, and to realize the remote control and data acquisition of the street light controller through the gateway.
