隨著科技發展，路燈已成為各國不可或缺的基礎建設。隨著人口密集度的提高，路燈數量也隨之增加，使得路燈的監控與維修成為管理上的重點。
現行的路燈監控方式是依據中央氣象局公布的日出日落時間統一調整控制，較為僵化。此外路燈發生故障的時候，通常需要工程人員不定期巡查或是依靠熱心民眾告知，無法及時發現路燈故障狀況且耗費人力與時間。
本論文設計與實作一整合環境感測、自動控制與路燈故障監測回報功能的智慧路燈控制系統。此系統採用LoRa無線通訊以星狀結構連結數個智慧路燈控制裝置，將環境感測數據、自動控制狀態與故障偵測結果等資料，透過燈群轉發站傳送給中央監控系統進行監控、分析與應用。另提供兩種控制模式，第一種適用於市區、人口密集地區，智慧路燈控制裝置透過感測器取得環境亮度，自動於日夜時控制路燈的開關，亦可在惡劣天氣造成環境亮度不足時，自動開啟路燈以提升用路安全；第二種適用於郊區、夜間人煙稀少之地區，智慧路燈控制裝置透過感測器偵測有行人時，才自動開啟此路段的路燈，達到節省偏僻地區路燈用電量。相較於僵化的固定開關方式，更能因地制宜的實施路燈配設與省電計畫。此外智慧路燈控制裝置根據與住宅距離和空氣溼度等資訊，透過模糊控制調整路燈的色溫，高色溫燈光可提高駕駛的注意力，降低分神的情況發生；低色溫燈光不只於雨天和濃霧天氣時穿透力較佳、提升用路安全，也減少抑制人體分泌褪黑激素的機會，提升周遭居住品質。路燈故障監測系統，採用感測器取得路燈照度、耗電量等資訊，並將判別結果回傳給中央監控系統，省去以往仰賴人力通報的程序，提升故障路燈處理時效。

With the development of technology, streetlights have become an indispensable infrastructure for all countries. The number of streetlights has increased with the population density, making the monitoring and maintenance of streetlights a key management issue.
The current method of street light monitoring is mainly based on laying physical control lines for series control, and the switching time is adjusted and controlled uniformly according to the sunrise and sunset times announced by the Central Weather Bureau, which is relatively rigid. In addition, when the streetlights are out of order, it is usually necessary for engineers to inspect them from time to time or rely on enthusiastic citizens to inform them, which is labor-intensive and time-consuming.
This paper designs and implements a smart streetlight control system that integrates environmental sensing, automatic control, and streetlight fault monitoring and reporting functions. The system uses LoRa wireless communication to connect the devices in a star-like structure, and transmits the environmental sensing data, automatic control status and fault detection results to the central monitoring system for monitoring, analysis and application. The first one is suitable for urban and densely populated areas, where the intelligent street light control device controls the street light during day and night according to the ambient brightness, and also automatically turns on the street light during bad weather to enhance road safety. It is also possible to implement localized streetlighting and power saving plans. In addition, the color temperature of the streetlights is controlled by fuzzy information such as distance from the house and air humidity. High color temperature lights can improve driving concentration and reduce distraction; low color temperature lights not only have better penetration in rainy and foggy weather, but also reduce the chance of inhibiting melatonin secretion in human body and improve the quality of living around. The street light failure monitoring system uses sensors to obtain information on street light illumination and power consumption, and sends it back to the central monitoring system to improve the processing time.
