北斗在远程人防警报系统中的应用

摘要

To against the shortcoming in geographical limitation of traditional alarm systems for civil air defense, the weather-proof remote civil air defense alarm system without communication blackout has been designed by adopting the message communication function of Beidou satellite. The man machine interface of the host computer is developed under Visual Basic environment, with the single chip computer as the main controller to achieve the design of alarm terminal software and hardware. The system can realize the functions of sending single or group alarm commands and feeding back the results, in addition, the alarm terminal can also convert the text content into speech broadcast. The results of experimental test indicate that the system implements remote alarm function and runs stably and reliably.%针对传统的人防警报系统受地域限制的缺点，提出利用北斗的报文通信功能，设计了一套全天候、无通信盲区的远程人防警报系统。系统的上位机人机界面是在Visual Basic环境下开发的，以单片机为主控制器完成警报终端软件和硬件设计。系统可实现单个或群发警报指令的发放与反馈的功能，同时系统的警报终端还可将警报的文本内容转换成语音广播报警的功能。试验测试结果表明该系统实现了远程警报功能，且运行可靠、稳定。
