【摘要】：人防警报网络是防空部门用来及时精确地向人民发放预警信号的专用网络,它的建设与国家和人民生命财产安全息息相关。随着经济的发展,城市建筑越来越密集,传统的基站式防空警报网络时常出现接收不到警报信号的情况(即盲点问题),并且定点安装导致战时抗毁能力差。因此,研究出一种网络覆盖面大、抗打击能力强的新型防空警报设备刻不容缓。本文针对现有的人防警报网络盲点问题和抗毁性差的缺点设计了一种基于自组织网络技术的人防专用网络路由器。根据防空警报网络的设计要求,通过对经典自组网路由协议的深入研究,结合自组织网络的工作原理和特点,制定出一种适合人防专用的网络路由协议OL-AODV,并利用仿真软件NS2对OL-AODV和AODV(自组网按需距离矢量路由协议)进行仿真比较,在相应场景下对包到达率、平均端到端时延等性能指标进行分析对比,论证了该协议应用在人防专用网络的可行性。本文路由器硬件上以STM32F103ZET6为控制核心,无线数传模块作为信号收发装置,并应用了路由通信协议OL-AODV使其同时具备警报终端和中继路由的功能。通过警报测试验证了本文设计的人防专用网络路由器能够根据不同警报信号及时和准确地完成相应警报的发放,由其构成的人防警报网络具有覆盖面积广、抗毁能力强、可移动的特点,符合现代人防警报网络的需求。
[Abstract]:Civil air defense alarm network is a special network used by air defense departments to issue early warning signals to people timely and accurately. Its construction is closely related to the safety of life and property of the country and people. With the development of economy, urban buildings are becoming more and more dense. The traditional base station air defense alarm network often can not receive the alarm signal (that is, blind spot problem), and the fixed point installation results in poor anti-destruction capability in wartime. Therefore, it is urgent to develop a new type of air defense alarm equipment with large network coverage and strong anti-attack capability. Aiming at the blind spot problem of the existing civil air defense alarm network and the shortcoming of poor survivability, a kind of special network router for civil air defense based on self-organizing network technology is designed in this paper. According to the design requirements of air defense alarm network, through the in-depth study of the classical ad hoc network routing protocol, combined with the working principle and characteristics of the ad hoc network, A network routing protocol OL-AODV suitable for civil air defense is developed, and the OL-AODV and AODV (ad hoc network on-demand distance vector routing protocol) are simulated and compared by using the simulation software NS2, and the packet arrival rate is compared in the corresponding scenarios. The average end-to-end delay and other performance indexes are analyzed and compared, and the feasibility of applying this protocol to civil air defense private network is demonstrated. In this paper, STM32F103ZET6 is used as the control core, the wireless data transmission module is used as the signal transceiver, and the routing protocol OL-AODV is used to make it have the functions of both alarm terminal and relay routing. Through the alarm test, it is proved that the civil air defense network router designed in this paper can timely and accurately complete the issuance of the corresponding alerts according to different alarm signals. The civil air defense alarm network composed by the router has a wide coverage area and a strong survivability. Mobile features meet the needs of modern anti-alarm networks.
