民航机场数字集群系统的建设方案

On the Necessity and Solutions of Construction of Civil Aviation Airport Digital Trunking System

文章概述机场现有模拟集群系统的弊端和不足,从业务需求和系统安全方面分析建设机场数字集群系统的必要性和可行性,并结合机场发展的前景和特点,采用基于数字时分多址技术的泛欧集群无线电(Trans European trunked radio,TETRA)系统标准,最后给出在机场具体现实的解决方案,满足机场业务的需求。

This paper describes the the neces^ty and feasibility of building t quirements and system security. Taking opment, it uses the TETRA standard sy nally gives the concrete realistic solution shortcomings of existing airport analog trunking system, and analyzes he airport digital trunking system from the perspective of business re- into consideration of the prospects and characteristics of airport devel- stem based on digital time division multiple accesses （TDMA）, and fi- s to meet business needs in airport.
