摘　　要：由于ISA总线数据传输率低、不支持资源的自动配置,逐渐被性能突出的PCI总线所取代.在利用PCI9052的ISA模式开发的CAMAC机箱控制卡上,采用CPLD实现逻辑极性转换,以接收上位机的总线信息,通过译码操作实现对CAMAC机箱中各模块的控制,并生成状态与CAMAC总线相适应的输出.采用Driver Works编写了基于Windows2000平台的WDM驱动程序,以支持应用程序对控制卡的访问.通过测试表明,控制卡不仅实现了数据在上位机和下位机的正常传输,而且有效地控制了CAMAC机箱中各模块,从而完成对齿轮类工件的测量.Because its data transmit rate is low and automatical configuration of the resources is not supportable, ISA bus is gradually replaced by PCI bus. On CMMAC box control card developed in ISA mode of PCI9052,CPLD is adopted to carry out the logic conversion, the bus information is received from computer, the information after coding controls all the cards in the CAMAC box, and state signals matching CAMAC bus are output. WDM drive program is written by DriverWorks and run on Windows 2000, application program is allowed to call the control card. Experiments show that the data transmission between computer and CAMAC box is achieved, the control card controls all modules in box effectively to fulfil the task of gears measurement.
