摘　　要：结合自研CPCI 422模块,参照已经发布的IVI类驱动规范,探讨422驱动函数的规划方案。由于IVI有关422通信类仪器尚未制定类驱动规范,在此尝试不借助NI公司提供的驱动向导开发422类驱动库,制定一种较为简单通用的422仪器类驱动规范,并针对自研模块开发专用驱动库,同时自己研制简易的能代替NI公司配置引擎的程序,实现通过编辑配置文件链接类驱动和专用驱动,并且自动加载专用驱动库的功能。该方法和规则对于其他虚拟仪器驱动程序的开发具有参考与推广价值。The design of CPCI 422 driver based on IVI specification is introduced. For the IVI foundation has not released 422 communication class,actually,it tries to design a kind of simple 422 communication class specification, and a kind of 422 class driver and specific driver refers to IVI class specifications without instrument driver wizard offered by NI. At the same time,it develops a simple program which has the function of replacing IVI configure engine offered by NI and dynamic loading specific driver library through editing configure file. This method and IVI specification are valuable to develop the driver of other virtual instruments.
