摘　　要：SF_(6)气体密度、分解物和微水含量监测装置被大量用于现代电网监控系统中。这些类型多样的监控装置组成测控网时,采用的总线类型及协议种类繁多。另外,监控系统选择的CPU等硬件及软件差异也很大,这些因素综合在一起导致监控系统的兼容性、互换性变差。为此,研究分析了多总线统一驱动及其在工业边缘普遍采用的Linux、WinCE跨硬件平台的移植问题,提出了统一设备驱动在不同操作系统下的技术思路和嵌入式跨平台统一设备驱动模型,建立了设备驱动程序在不同操作系统下的移植方法。依据这个思路与方法,能快速完成驱动软件功能在不同嵌入式系统之间的快速移植,可降低技术难度,提高监控软件开发效率,增强SF_(6)气体密度继电器在多总线场景中的适应性。本方法不仅适用于SF6气体密度继电器及SF6分解物和微水含量状态监测装置组成的自动化监控系统,而且对解决类似工业场景中的瓶颈技术也具有很高的参考价值。The monitoring devices for SF_(6) gas density,decomposed substances and micro water content are widely used in modern power grid monitoring systems.When these various types of monitoring devices form a monitoring and control network,a wide variety of bus types and protocol types are used.In addition,the hardware like CPU etc.,and software selected by the monitoring system are also very different,and these factors combine to lead to poor compatibility and interchangeability of the monitoring system.In view of this,the paper first studies and analyzes the cross-hardware-platform porting issue of the multi-bus unified driver and in Linux,WinCE commonly used at the industrial edge,and then,proposes the technology idea of unified device driver in different operating systems and the embedded cross-platform unified device driver mode.Finally,the paper establishes the porting method of device driver under different operating systems.According to this proposed idea and method,the driver software function can be quickly transplanted between different embedded systems;the technical difficulty can be reduced;the development efficiency of monitoring software can be improved,and the adaptability of SF6 density relay in multi-bus scenarios can be enhanced.This method is not only suitable for the automatic monitoring system composed of SF6 gas density relay and SF6 decomposed substances and micro-water content status monitoring devices,but also has a high reference value for solving the bottleneck technology in similar industrial scenes.
