摘　　要：普适计算是计算模式的发展趋势。现场建档系统是其中一类重要应用,这通常需要在多台设备间互通性质不同的数据。为实现功能重用,加快建档系统的开发,提出一种支持异质数据通讯的软件平台,采用“订阅/发布”模式支持传输关系的动态调整及系统的易扩展性;针对异质数据设计不同传输结构保证传输的高效;平台的调用接口屏蔽了数据传输的实现细节,简单易用。该平台已成功用于课堂建档系统,验证了它在现场建档系统构建中的功用。Pervasive computing is the trend of development for computing mode. On-the-spot archiving system, as one of the important applications, normally involves transferring heterogenous data between multiple devices. A software platform for supporting heterogeneous data transfer was presented in this paper. The platform utilizes subscribe-publish pattern as transmission mode to enable runtime adjustment of transmission relationship and extendibility of the system. And the platform constructs distinct transmission relationship structures for different kinds of data to maintain high efficiency. Moreover, the platform provides simple and easy-to-learn API which conceals implementation details of data transfer. This platform has been applied to a class archiving system, which proves the practicability of the platform.
