摘　　要：针对安检系统各子系统与外部系统交互信息的接口方式不同,但其交互的消息格式均遵循一定的消息规范协议,且安检各子系统处理消息逻辑也基本相同的特点,本文提出了机场安检系统外部接口平台的设计与实现,该平台实现了基于.NET 2.0的轻量级MEF的编程框架,支持动态拓展和装载不同接口访问器,实现不同接口方式下的消息交互,解决安检系统与外部系统有多种接口方式维护不同接口程序问题。实践表明,该平台能够兼容Socket、MQ、Web Services等不同接口方式,实现安检各子系统同外部系统信息交互。In view of the interface between the subsystems of the security inspection system and the external system is different, the interactive message formats follow certain message specification protocols and the subsystem of the security check system have the same basic message process logic,this paper presents the design and implementation of the external interface platform of airport security system, this platform implements lightweight MEF based on.Net 2.0, supports dynamic expansion and loads different interface accessor realizing different interface mode, solves the problem of multiple interface program versions between the security system and the external system. The practice shows that the platform can be compatible with different interfaces such as Socket, MQ, and Web Services and so on, so that each subsystem of the security system can interact with the external system.
