危险区域无线侦测指挥系统

Wireless detecting and controlling system for dangerous area

基于无线技术,提出一种在危险区域进行侦测及指挥的解决方案。系统采用分层结构,分为探测球层、终端层与指挥中心层。探测球层包含了音视频、空气质量等检测模块。终端层基于Liod开发板和Linux系统,配合无线模块实现音频视频采集、空气质量检测、区域报警等功能,通过Ad Hoc无线自组网络与其他终端以及指挥中心进行通信。指挥中心担负着整体调度的职责。利用该系统,可以实现现场指挥、图片传输、实时音频传输、人员定位、现场地图绘制及远程传输等操作,为危险区域的信息收集以及指挥人员的决策提供有力支持。

Based on Ad Hoc networks,a solution of the system is proposed that can detect information of dangerous system and help people to make decision.The system adopts a layered-manner and has three layers：detecting ball layer,terminal layer and commanding center layer.Detecting ball layer contains modules of video,audio and air quality detecting.Terminal layer is based on Liod development board and Linux system.This layer has functionality of collecting video and audio signal,detecting air condition and alarming.A terminal can communicate with other terminals and commanding center with ad hoc networks.Then commanding center plays a role of scheduling.With such a system,operations which include realtime commanding,picture transfer,realtime audio transmission,people locating and area map drawing can be conducted in dangerous area.
