摘　　要：由于VXI总线协议规定了详尽的电气和机械规范,同时又提供了灵活的通讯协议,在自动测试领域和其它多仪器系统中已经得到了广泛的应用。VXI器件研制中,上层控制软件和底层硬件、总线接口模块和功能实现模块之间是相对独立的,具有良好的模块化特征,因而相应部分的研制任务是可分的,可以同步进行。基于同样的理由,器件资源具有可继承、可移植的特征。文中首先介绍了作者研制的VXI总线消息基器件的结构和工作方式,并以此为例,说明了VXI消息基器件研制任务可分性,研制成果的模块化特征和可继承性等特点。最后。Since VXI bus protocol provided exhaustive mechanical and electric criterions and flexible communication protocol, VXI has been widely used in auto\|testing and other multi\|instrument systems. In developing of VXI based device, the controlling software and hardware, the bus interfacing module and task implementing module are independent of each other, in other words, the developing process is modularized. So developing of the according parts can be divided and be processed simultaneously. With the same reason, resources of the device can be easily inherited and migrated to other devices. In this paper, the structure and working style of a message\|based VXI device are provided. With this example, some characteristics of the developing of VXI message\|based devices, especially the task\|divisibility, modularization and inheritablity, are discussed. At the end, some problems in developing of VXI based device are presented.
