The working principle is as follows: computer mainboard detection card detects computer hardware to store the fault detection information in storage module and backup, computer mainboard detection card simultaneously gives the alarm controller with fault detection information transmission and reports to the police, and alarm controller passes through GPRS and GSM and gives the display terminal with fault detection information respectively, central host computer and mobile terminal, at this moment, central host computer can be transferred out computer hardware fault information and trouble solution database and show at display terminal, thereby can overcome when computer hardware breaks down, the processing cycle is long, waste time, hinder the problem of work and life.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
