机场行业是一个综合******行业，其涉及多个领域并在现代交通体系及城市发展中扮清着重要角色。机场作为航空运输业的基础设施，是航空公司运营的关键节点，承担着航班调度、旅客服务、货物处理等多项职能，机场不仅服务于航空运输，还与地面交通系统紧空相连，如地铁、公交、出租车等，形成了一个立体的交通网络是城市交通体系的重要组成部分。
The airport industry is a comprehensive service industry that covers many fields and plays an important role in the modern transportation system and urban development. As the infrastructure of the air transport industry, the airport is a key node of airline operation, undertaking a number of functions such as flight scheduling, passenger service, cargo handling, etc., the airport not only serves air transportation, but also connects with the ground transportation system, such as subway, bus, taxi, etc., forming a three-dimensional transportation network is an important part of the urban transportation system.
现代化机场建筑体量巨大，一个主建筑体德占地面积可以达到几万方，需要大量的人员进行管理、安保、维护，大大提高了调度、沟通的难度，在大量的服务人员情况下，统一智能的调度管理系统起到不可或缺的作用
The volume of modern airport buildings is huge, and a main building covers an area of tens of thousands of square meters, which requires a large number of personnel for management, security and maintenance, which greatly improves the difficulty of scheduling and communication, and plays an indispensable role in the unified and intelligent dispatching management system in the case of a large number of service personnel
现代化交通枢纽人员流量巨大具有人员潮汐效应，每日的人流吞吐量达到几万甚至几十万
The security requirements are high, and the modern transportation hub has a huge flow of people, with a tidal effect of personnel, and the daily flow throughput reaches tens of thousands or even hundreds of thousands
现代化交通枢纽对安保要求极高，需要及时的发现隐患、确定位置、及时警报及时处理
Modern transportation hubs have extremely high security requirements, which require timely detection of hidden dangers, determination of location, timely alarm and timely treatment
我们为机场制定了一套IEC-PDT集群系统它具有信道资源叠加及动态分配的特点，适合进行多基站互联，该网络可以进行多层级管理，并且设有中心基站。中心基站通常配有交换控制功能的单位，如信号匹配单元等。由于其星型网络结构，当某个基站损坏而中心基站和其他基站没有问题时，并不影响其他基站的使用，满足各个部门之间的无缝沟通
We have developed an IEC-PDT trunking system for the airport, which has the characteristics of channel resource superposition and dynamic allocation, suitable for multi-base station interconnection, the network can be managed at multiple levels, and has a central base station. The central base station is usually equipped with units with switching control functions, such as signal matching units. Due to its star network structure, when a base station is damaged and the central base station and other base stations have no problems, it does not affect the use of other base stations, meeting the seamless communication between various departments
