摘　　要：将XML技术引入民航离港系统,用于在旅客办理离港手续时更灵活地打印旅客的登机牌和行李牌,方便旅客离港出行。具体方法是通过数据类型定义以及对登机牌数据流和行李牌数据流各项进行XML格式的配置设置,并通过离港前端程序对配置项设置规则的解析处理,实现离港主机下发的旅客值机的登机牌和行李牌数据流内容根据XML配置规则进行相应转换并将处理结果送往登机牌和行李牌打印机打印成要求的结果。通过论述的数据流定义与转换的设计成果,增强了离港系统打印功能的灵活性和扩展性,满足了离港系统在全国机场投产过程中客户提出的个性化打印需求并增强了离港前端系统在投产实施过程中对不同品牌打印机适配的灵活性,也改变了因为各地机场采购的登机牌和行李牌打印机品牌和型号不同而要求离港系统修改打印模块程序来适应的被动局面。XML technology is introduced into the departure control system of civil aviation. It is used to print the boarding pass cards and bag tag cards of passengers more flexibly when they go through departure formalities,so as to facilitate the departure of passengers. The specific method is to configure the data stream of boarding pass and baggage pass in XML format by defining the data type,and to analyze and process the rules of setting configuration items through the front-end program of departure control system(DCS),so as to realize the content of boarding pass and baggage pass data stream of departing host according to the XML configuration rules and line the corresponding conversion and send the processing results to the boarding pass and baggage plate printer to print the required results. Through the design results of the definition and conversion of data flow discussed,the flexibility and expansibility of the printing function of the departure control system are enhanced,the personalized printing requirements of the customers in the process of the departure control system putting into operation at the National Airport are satisfied,and the adaptability of the departure front-end system to different brands of printers in the process of putting into operation is enhanced. Flexibility has also changed the passive situation of requiring the departure control system to modify the printing module program to adapt to the different brands and models of boarding pass printers(BPP) and bat tag printers(BTP) purchased at airports.
