Abstract
The utility model discloses a portable fault detector for an electronic information system. The portable fault detector comprises an acquisition card, a master controller and a display, wherein the acquisition card is electrically connected with the electronic information system to be detected, the master controller is used for carrying out fault analysis, and the display is used for displaying fault causes. A fault signal input end of the master controller is in communication connection with an output end of the acquisition card through a CAN bus so as to receive digital signals. The display is in communication connection with an output end of the master controller through an RS232 chip so as to display the fault causes determined by the master controller based on fault phenomena. A power supply output terminal of a power supply is electrically connected with working voltage input ends of the master controller, the acquisition card, the display, the CAN bus and the RS232 chip through leads in a corresponding manner. Main components of the fault detector are all of chip level, and the fault detector has the advantages of small size, low power dissipation and convenient carrying.
Description
Technical field
The utility model belongs to fault diagnosis field, relates in particular to a kind of fault locator for electronic information.
Background technology
Develop rapidly along with computer technology, electronic technology, it is day by day complicated that electronic information has become, in this day by day complicated electronic information, the appearance of fault is difficult to avoid, how to determine fast and efficiently the failure cause of electronic information, become problem demanding prompt solution.
In addition, usually adopt at present fault tree analysis to determine to occur the various possible causes of product bug, but there is following deficiency in traditional Construction of Fault Tree method: 1) not consider the failure cause order of severity and frequent degree in the process of Construction of Fault Tree; 2) even considered the failure cause order of severity and frequent degree, but computation process needs mathematical model, is difficult to realize on engineering.
The utility model content
But the purpose of this utility model be to provide a kind of when electronic information breaks down the guide maintenance personnel solve quickly and accurately the electronic information fault locator of fault.
The technical solution adopted in the utility model is: a kind of portable electronic information system failure detection instrument comprises:
Capture card, described capture card have the input interface that is connected for the electric interfaces of electronic information to be measured, so that the signal that collects is carried out analog to digital conversion, and characterize the digital signal of phenomenon of the failure by the output terminal output of capture card;
Be used for carrying out the primary controller of fault diagnosis, the fault-signal input end of described primary controller is by the output terminal communication connection of CAN bus and capture card, to receive described digital signal;
Display, described display is connected by the RS232 chip communication with the failure cause output terminal of primary controller, is used for the failure cause that shows that primary controller is determined according to phenomenon of the failure; And,
Power supply, the power supply lead-out terminal of described power supply is by the operating voltage input end corresponding electrical connection of wire with described primary controller, capture card, display, CAN bus and RS232 chip.
Wherein, described portable electronic information system failure detection instrument also comprises housing and circuit board, and described capture card and primary controller are welded on described circuit board, and described circuit board is installed in housing, the input interface of described capture card exposes by housing, and described display is embedded on described housing.
The beneficial effects of the utility model are: the main devices of the portable electronic information system failure detection instrument that the utility model provides is chip-scale, has advantages of that volume is little, low in energy consumption and is convenient for carrying.
