数字无线通信技术在森林防火中的应用

森林防火数字无线通信包括超短波通信网、短波通信网、卫星通信系统和应急通信保障车等几个方面;在日常预防及扑火应急通信中超短波通信网的作用是最为重要的,同时超短波通信网为用户实现了专用链路资源,为扑火应急通信提供了数据远程传输的手段;超短波通信基站的建设依托于林场资源及地理环境等条件,所以在基站的基础设施建设方面也提出了很多挑战。重点介绍数字超短波通信网的建设和火场应急情况下的结合便携通信设备、卫星设备和应急通信保障车的无线语音、数据和视频的传输方案及应用。

Application of digital wireless communication in prevention of forest fires

Forest fire prevention communication includes ultrashort wave communication system,shortwave communication system,satellite communication system and emergency communication vehicle. In daily work,ultrashort wave communication system plays the most important role,in which a dedicated link is built for users,and a means of remote data transmission is provided. The construction of ultrashort wave base-station depends on forest resources and geographical conditions,therefore it gives us more challenges in infrastructure construction of the base-station. The constrcution of digital ultrashort communication system,and the data and video transmission solutions of portablecommunication device,satellite equipment,emergency commu-nication vehicle are introduced emphatically.
