基于嵌入式 Linux 的真空断路器特性检测仪的设计与实现
摘要
随着铁道电气化改造的快速发展,真空断路器由于具有分断能力强、寿命长、安全
可靠、噪声小、可在环境恶劣、操作频繁的条件下工作的显著特点,已经在铁路系统获
得广泛的应用。真空断路器的机械特性直接影响其开关特性和使用寿命,是其重要的技
术参数。因此,加强对真空断路器机械特性的检测与诊断,具有十分重要的现实意义。
论文首先介绍了真空断路器及其机械特性的检测技术,接着提出了仪器的总体设计
方案,然后对仪器中的硬件、操作系统和应用软件进行了选择和分析。选用嵌入式主板、
DOC 2000、液晶触摸屏、微型打印机和数据采集卡等硬件,实现了一套真空断路器检
测仪器。软件上通过裁减 Linux- 内核、构建微型根文件系统和设置 GRUB 等步骤
构建嵌入式 Linux 系统。接着运用 MiniGUI 编写界面优美、人机交互性能优良的操作控
制界面程序,然后运用 MySQL 数据库编写相应的程序实现检测结果的存储、查询和传
输。最后将 MiniGUI、MySQL、相应设备驱动程序和应用程序可执行文件移植到目标平
台上并调试通过。
本设计将最新的嵌入式技术应用于真空断路器特性测试仪中,实现了一套高精度、
智能化、网络化的检测仪器,该仪器具有体积小、可靠性高、硬件资源成本低、软件开
源免费等特性,因此具有较高的实用价值。

Abstract
Design and Realization of A Characteristics Tester for
Vacuum Circuit Breaker Based on Embedded Linux
ABSTRACT
With the rapid development of railway electrification transformation, the vacuum circuit
breaker which possess a lot of advantages such as high current interrupting capabilities, long
life, safety, reliability, small noise, working under bad environment and operating frequently,
has been used widely in the railway system. Furthermore, as the important technical
parameter of vacuum circuit breaker, mechanical characteristic’s performance is directly
related to the switch characteris and its lifetime. So it has the extremely vital practical
significance to strengthen the examination and diagnosis of vacuum circuit breaker.
At first the paper introduces the vacuum circuit breaker and its mechanical
characteristics’s measurement technology, then proposes the overall scheme of the instrument,
after that the instrument’s hardware, operation system and application software is choosen and
analyzed. A data acquiring and processing system is designed using embedded main board,
DOC 2000, touch screen, micro-printer and data acquisition card(DAQ). Em
