太阳能路灯自动报警系统

Automatic Alarm System for Solar Street Lamps

摘要: 针对传统路灯作为交通基础设施在功能上单一、缺乏与其他设施联动能力的背景下。本项目聚焦于交通事故监测系统的研发，旨在提升道路交通安全水平。在感知层面，采用毫米波雷达传感器实时监测车辆速度变化，精准捕捉急减速情况。能源层面，利用单晶硅太阳能板搭配锂电池组，实现太阳能供电，即便在阴雨天也能保障系统续航多天，且具备智能功耗控制，无车辆时自动进入深度睡眠模式，检测到目标后瞬间唤醒。数据处理依靠STM32H7与雷达预处理芯片的组合。在报警功能上，不仅进行声光警示，还借助NB-loT/5G向交管中心远程上报报警信息，实现多级报警触发。

Abstract: Against the background that traditional street lamps, as traffic infrastructure, have a single function and lack the ability to link with other facilities, this project focuses on the research and development of a traffic accident monitoring system, aiming to improve the level of road traffic safety. At the perception level, a millimeter-wave radar sensor is adopted to monitor the real-time changes of vehicle speed and accurately capture the sudden deceleration situation. At the energy level, monocrystalline silicon solar panels combined with lithium battery packs are used to realize solar power supply, which can ensure the system’s continuous operation for multiple days even on rainy days. It also has an intelligent power consumption control function: it automatically enters the deep sleep mode when no vehicles are detected, and wakes up instantly once the targets are identified. Data processing relies on the combination of STM32H7 and radar preprocessing chips. In terms of the alarm function, it not only issues sound and light warnings, but also remotely reports alarm information to the traffic management center via NB-IoT/5G, thus achieving multi-level alarm triggering.
