The Design And Implementation Of Airport Operating Messaging Middleware Management System

With the rapid development of civil aviation industry, all aspects of airport management have been put forward new demands, such as the information terminal interaction in different production management system, the integration of different architectures, the information update frequency settings. Such differences distributed systems achieve efficient and reliable message delivery mechanism and platform-independent data exchange. The system software hierarchy structures is particularly important,which to be able to communicate between different platforms, to shield the agreement between the various platforms and features, to achieve the application of collaboration. In the absence of a common standard, middleware system based on a variety of messaging is difficult to achieve interoperability and seamless connectivity.This article describes basic concepts of JMS and message composition, message communication and message interfaces:Point to Point (PTP) and Publish/Subscribe (Pub/Sub) mode. Taking into account the JMS specification, the article use XML as the message in the form of JMS messaging middleware for the design of the study. This paper also analyzes the current status and problems of the middleware application system services. The hierarchical structure analysis system platform and made the demand analysis. By combining OSGi technology, it increases the system flexibility and scalability. Through OSGi module way, the module interacts with the deployment of services and supports modular system platform optimized three-level structure. The hierarchy of functionality uses Struts and Spring package. Using this software development structure is basically solved using WEB technology to meet the basic operations and client needs.In order to achieve interoperability between applications and the client and server can provide synchronous and asynchronous connections, including three middleware modules:middleware management module, middleware communication modules, middleware channel configuration module. According to the message middleware interact in different ways and the actual situation, it can be defined four types of events news events including query events, data events, integrated systems of business events, business events other subsystems take the initiative to meet the messaging business needs. Application subsystems achieve information exchange between the various subsystems through the middleware communication modules. Generally, information exchange processes includes four parts:data sources, data storage and analysis modules, subsystems, middleware communication modules, when the data needs to be passed, applications can easily transfer data.
