一种基于构件的手机可重构虚拟仪器技术

针对手机测试系统对便携式测量提出的在线升级和功能调整的要求，提出了基于构件的手机动态可重构测试系统。采用动态XML解析器模型实现了手机端测试系统的动态解析、构件的查找和装配，形成一个测试功能可以根据测试任务快速重组的测试系统。提出了支持面向发布/订阅模式的仪器构件模型，在此基础上设计了系统数据模型和事件模型来实现构件之间消息的传递与数据的更新。以声音信号采集分析仪器和3种人体生理信号采集测试系统为应用例子，进行测试。结果证明了该平台的可实现性，并能够满足手机测试系统对便携式测量提出的在线重构和功能调整的要求。

Component-based dynamic reconfigurable test systemon mobile phone

In order to achieve online upgrade and function adjustment of portable measure, this paper proposed a component-based dynamic reconfigurable test system on mobile phone. It uses dynamic XML parser to actualize dynamic resolving, components querying and assembling of mobile terminal test system, aiming at forming a system which can be quickly restructured according to the test task. This paper also put forward an instrument component model supporting for the Publish/Subscribe pattern. On the basis of that, this paper designed the corresponding data model and event model to achieve the component message transfer and data update. At last, it gave examples of a sound signal acquisition analysis instrument and three human physiological signal testing systems. Experimental results prove that this platform can be realized, and it can meet the reconstruction and function adjustment demands put forward by mobile phone test system for portable testing.
