DESIGN AND REALIZATION OF A NEW MECHANICAL PROPERTIES TESTER FOR VACUUM CIRCUIT BREAKER BASED ON EMBEDDED LINUX AND MINIGUI

摘要

This paper introduces a hardware scheme of the mechanical properties of vacuum circuit breaker at first. A data acquiring and processing system is designed by using a technical grade mainboard, DOC 2000, touch screen, micro-printer and data acquisition card (DAQ). Then a set of software is designed for the measuring system. The device's operation system is constructed by cutting down standard Linux-2.4.18 kernel, constructing subminiature root file system and setting GRUB etc. After that, in order to get a graceful and friendly human-computer interface, the control interface program is realized by using MiniGUI. Finally MySQL is used to write program which realizes test result's storage, inquiry and transfer. The measuring device will be the efficient tool for measurement and maintenance of vacuum circuit breaker.
