Computer detector and method for implementing computer testing instrument

Abstract

The invention discloses a computer tester and its realization method. Its control circuit is controlled by a microprocessor, and a database, a test circuit with a physical connection adapter interface and a logic signal interface of the tested circuit, and a signal generator are used. Device, communication interface with personal computer, man-machine dialogue module and other functional components, its system control software includes system self-inspection process, test process, signal generation process, diagnosis process, communication process with PC computer, database operation process, stability test Therefore, compared with the existing technology, it can detect the computer without relying on the BIOS self-test of the computer under test. At the same time, it also has various test methods and strong functionality; the test range Wide range, from desktop computer to notebook computer, and even other circuits, with strong applicability; simple software interface, flexible form of man-machine dialogue, easy to use and so on.

Description

technical field [0001] The invention relates to a device for comprehensive testing of computer systems and its realization method, in particular to a computer tester and its realization method. technical background [0002] At present, the existing equipment mainly aimed at comprehensive testing of computer systems includes computer motherboard fault diagnosis cards, also called POST cards. Existing diagnostic cards simply display the self-diagnostic fault codes of the main board’s 80H port (from the POST self-diagnosis program of the BIOS), and then you can roughly know the scope of the fault by consulting the meaning of the codes on the manual of the diagnostic card. It does not have data processing capabilities, and the display method is simple and abstract. In the book "PC Upgrade and Maintenance" published by People's Posts and Telecommunications Press in 2001, the 9th line from the bottom on page 869 "Although the diagnosis completed by the system POST is not very tho...

AI Technical Summary

Problems solved by technology

Moreover, this kind of diagnostic card does not have self-test capability. Once the diagnostic card itself makes an error, it cannot accurately diagnose the error of the computer.

In addition, they are generally only used for desktop computers, and they are helpless for notebook computers or even computer peripherals or other circuits and components, so the scope of use is too narrow

At present, there are also expensive testing equipment that are fixed and cannot be moved online for computer production lines, and they are not suitable for scheduled computer testing and circuit testing.
