无线多跳防空警报遥控系统设计

Design of Wireless Multi-hop Air-Raid Siren Remote Control System

针对目前无线大区制防空警报遥控系统中存在的二次报警能力弱和中心发射塔无线电信号覆盖范围有限等问题,提出一种基于超短波数传电台的无线多跳防空警报遥控系统,在该系统中实现警报控制信号多跳传输。给出总体设计方案和关键设计技术,并设计了一种适合该系统的路由协议。基于网络仿真工具OPNET构建了该系统的仿真框架,对系统常用业务进行建模,分析系统警报发放时延和警报回示时延两个重要参数,仿真结果表明该系统性能达到设计要求,为解决现有系统中存在的上述问题提供了一个有效的可选方案。

According to the weakness of secondary alarming ability and the limitation of the radio range of central transmitter tower in the present wireless large covering air - raid siren remote control system, a new wireless self - organizing air - raid siren control system based on UHF data transceiver is proposed,which transports alarming control instruction by multi- hop mode. The overall design scheme and the key design technology are introduced. A routing protocol which is suitable for the system is designed. The system network simulation framework and its common applications mode based on OPNET is deve - loped. The important parameters of alarming informing delay and alarming feedback delay are analyzed. Simulation results indicate that it reaches the design demand and it is an effective alternative for schemes which try to resolve the problems in the present systems.
