应急救援行动中通信频谱资源保障研究

Research on communication spectrum resource guarantee in emergency rescue operation

在灭火、抗震救灾以及抗洪抢险等应急救援现场,参加救援单位多、人员复杂,各类救援指挥信号、灾民求救信号、新闻报道信号、后勤补给以及物资发放等用频需求集中,极容易造成通信设备自扰和互扰问题,从而干扰应急救援指挥通信。为了规避这种风险,文章分析研究了大型应急救援行动中通信频谱资源保障问题,给出了合理的应对措施。

In fire, earthquake relief, and fighting and emergency rescue site, join the rescue unit, more complex, all kinds of rescue command signals, victims of distress signal, news reports, supplies, and supplies distribution with frequency requirements such as concentration, extremely easy to cause communication equipment since the interference and mutual interference problems which interfere with the emergency rescue command communication, in order to avoid the risk, The purpose of this paper is to study the problem of communication spectrum resource guarantee in large emergency rescue operations and give reasonable countermeasures.
