随着电子技术的发展,无线电通信技术也日新月异。超短波小型无线电话机由于避开了短波频段范图内频率拥挤的现象,况且它具有体积小,重量轻,灵活方便,声音清晰等特点,在护林防火无线电通信中,有着很大的适应性和良好的效果。几年来,我们在防火期间采用了辐射网和节点网两种组网方式,较好地完成了护林防火通信任务。现将我们的作法简介如下。一、林区护林防火的特点和对无线电通信的要求护林防火是一项社会性、群众性、时间性、季节性很强的工作,加上我省东部林区山高林密,交通不便,群众散居,生产分散,给护林防火工作带来很大的困难。为了适应这一特
With the development of electronic technology, the radio communication technology is also changing rapidly. Ultra-shortwave small-sized radiotelephone has avoided the phenomenon of frequency crowding within the short wave frequency band diagram, and has the characteristics of small size, light weight, flexibility and convenience, and clear voice. In the forest fire radio communication, it has great adaptability and good effect. Over the past few years, we used two kinds of networking modes of the radiation network and the node network during the fire prevention period, and well fulfilled the tasks of forest fire prevention communication. Here is a brief introduction of our practice. First, the characteristics of forest fire prevention forest and the requirements for radio communications Forest fire prevention is a social, mass, time, seasonal strong work, coupled with the eastern part of our province mountain forest, traffic inconvenience, the masses Diaspora, decentralized production brought great difficulties to forest fire prevention work. In order to adapt to this special
