基于RTMP的森林火灾预警监控系统设计

Design of Forest Fire Warning and Monitoring System Based on RTMP

高温是森林火灾发生的主要原因之一,对林区进行分布式温度监测是提早发现火灾隐患的有效途径。设计了一种使用Linux系统和实时传输协议进行温度等环境参数检测的森林火灾预警监控系统,系统终端节点集成温湿度、位置和视频采集功能,利用TCP和RTMP协议实现多个分布式终端节点数据和视频流的实时传输,在监控端实时监测多个地点的环境数据,排查潜在的火灾隐患。通过3个节点的测试,系统可以实现终端节点数据、视频汇聚,且使用FFmpeg进行视频拉流比传统VLC拉流速度快约10秒。

High temperature is one of the main factors of forest fires,thus implementation of distributed temperature monitoring maybe an effective way to detect fire hazards because of huge forest area.This article proposed a forest fire warning and monitoring system using Linux system and real-time transmission protocol.The system terminal nodes integrate temperature,humidity,location,and video acquisition functions,data flow including sensor information and video from abundant terminal nodes will be converged and transmitted using TCP and RTMP protocols.Potential fire hazards could be identified from data flow with the monitor terminal.System test was conducted with three terminal nodes which demonstrated the system achieved predefined functions such as data and video aggregation,and video streaming speed is about 10 seconds faster than traditional VLC media players.
