为了解决载机在研发过程中因**需求的不断改变而导致悬挂物管理软件升级维护和重新开发的问题，提出了即插即用的思想。希望将插件技术应用于悬挂物管理系统(SMS)，从而在不修改或少修改主程序的前提下，提高载机对新**的综合能力。以悬挂物管理系统为基础，首先介绍了插件技术的基本原理和插件的实现方式，然后根据悬挂物管理系统的组成和功能特性，总结插件技术在其中应用所要解决的关键技术，并对**综合平台和插件的功能划分、插件的接口设计、插件的调用过程等关键技术的解决方案进行详细论述，最后搭建一个**综合演示验证平台，验证该技术的有效性。

During the development of an aircraft,the software of Stores Management System (SMS) often requires redevelopment and upgrading maintenance due to the constantly changing of needed weapons.To solve the problem,the concept of plug-and-play was brought out.We hope to apply the plug-in technology to SMS and thus to realize the integration of new weapons with no or just a little modification to the main program.In this paper,an introduction is made to the basic principles of the plug-in technology and its realization method.Then,several key technologies for using the plug-in technology in SMS are summarized according to the composition and functions of SMS.In addition,the solutions of key technologies are presented,such as the function partitioning of weapon-integration platform and plug-ins,the design of plug-in interface,invoking process of plug-ins etc.A demonstration platform is built up to verify the effectiveness of our method.
