基于ARM的主动预警视频监控系统的实现

Implementation of Proactive Early-warning for Video Surveillance System

针对现在大多数监控系统对应急反应缺乏必要的支撑的情形,本文为其设计了主动预警功能。报警模块通过射频信号与开发板相连,开发板检测到报警信号后会通过与其USB接口相连的3G模块以主动拨号给用户手机的形式给予响应。通过GPIO驱动和报警协议的设计实现报警模块与片上系统GM8180之间的射频连接。

A proactive early warning system is designed to provide emergency reaction for traditional video surveillance system. Thealarm module is connected to the development tool through RF signal. Once potential danger is detected, the development tool, con-nected the alarm module through RF signal, will dial to the user through the 3G modem connected to the USB interface. The RFconnection between the alarm module and ARM is established after GPIO as weU as alarm protocols are properly designed.
