摘　　要：在Linux通用驱动程序的基础上,根据电缆绝缘电阻测试的功能需求,结合proc文件系统设计思想,完成基于嵌入式Linux系统的测试仪驱动程序的设计与开发。根据芯片接口设计介绍了读写操作的实现过程;利用中断和互锁机制提高系统效率和稳定性,通过系统调试证明此驱动程序运行时速度快、内存利用率高,能够满足系统需求,具有较好的工程应用价值。According to the functional requirements of cable insulation resistance testing, the driver based on embedded Linux system is designed and developed on the basis of Linux universal driver and combining with the proc file system design ideas. The implementation process of driver with the proc file is detailed analyzed. The interrupt and interlock mechanism are used to improve system efficiency and stability. With experiments proving, the driver run speed, memory utilization is high ,which can meet the system requirements and has good engineering applications.
