Abstract

The present invention relates to a kind of electronic equipment automatization test system, it uses the Auto-Test System platform of the trunk mixed structure of PXI, GPIB, is configured with instrument and slave displays such as digital multimeter, digital oscilloscope, signal generator, programme-controlled dc power, testing source, A/D and D/A module, numeral I/O module, matrix switch module and serial interface module；Wherein testing source is for from grinding module, and for providing specific pumping signal to some signal processing class board, slave display is for the output test of some image processing class board；Present system can effectively reduce the skill set requirements to maintainer, shortens maintenance time, reduces maintenance support cost, has certain promotional value.

Description

A kind of electronic equipment automatization test system

Technical field

The invention belongs to automatic test field, be specifically related to a kind of electronic equipment automatization test system.

Background technology

Along with the progress of science and technology, the complexity of electronic equipment improves day by day, causes the difficulty of its maintenance support to add Greatly, it once breaks down, and can solve problem though on-the-spot by the way of changing spare part, and fault board is had to depot repair Or sending technical staff to go to field maintenance, the maintenance support cycle is long, life cycle management maintenance cost is high.

Summary of the invention

Technical problem: the problem existed for above-mentioned prior art, the present invention provides a kind of electronic equipment automatic test System.

Technical scheme: the present invention relates to a kind of electronic equipment automatization test system, it uses PXI, GPIB trunk mixed The Auto-Test System platform built, is configured with digital multimeter, digital oscilloscope, signal generator, programme-controlled dc power, survey The instruments such as trial signal source, A/D and D/A module, numeral I/O module, matrix switch module and serial interface module and a pair show Show device；Wherein testing source is for from grinding module, and for providing specific pumping signal to some signal processing class board, pair is aobvious Show that device is tested for the output of some image processing class board.

The method have the advantages that

1, present system can effectively reduce the skill set requirements to maintainer, shortens maintenance time, reduces maintenance support cost.

2, the present invention efficiently solves the testing and diagnosing problem of certain electronic equipment, has certain promotional value.

Accompanying drawing explanation

Fig. 1 is the system principle diagram of the present invention.

Fig. 2 is bus communication schematic diagram of the present invention.

Fig. 3 is input equipment fault tree schematic diagram in the present invention.

Detailed description of the invention

Below in conjunction with the accompanying drawings and embodiment further illustrates technical scheme.

As it is shown in figure 1, a kind of electronic equipment automatization test system, it uses the automatic of the trunk mixed structure of PXI, GPIB Testing system platform, be configured with digital multimeter, digital oscilloscope, signal generator, programme-controlled dc power, testing source, Instrument and slave displays such as A/D and D/A module, numeral I/O module, matrix switch module and serial interface module；Wherein Testing source is for from grinding module, and for providing specific pumping signal to some signal processing class board, slave display is used for The output test of some image processing class board.

As in figure 2 it is shown, the industry control primary module on interface adapter uses PCM3362N computer module, module has attached symbol Close ISA and the pci bus of PC/104Plus specification, can directly communicate with isa bus and pci bus awaiting board card.

As it is shown on figure 3, according to testing requirement, whole test program comprises functional test and fault diagnosis two parts；Function Part of detecting is for the fault detect of testing component, and fault diagnosis part is used for diagnosing, positioning fault zone；Functional test part Use automated testing method, automatically call test resource and test, reduce artificial intervention as far as possible, to improve test speed Degree；Fault diagnosis part uses fault diagnosis expert system based on FTA；Its operation principle is fault diagnosis Knowledge is shown by the formal intuition of fault tree, is then passed through collecting and refine that to be converted into test software platform concrete Diagnotor；During test, system guides operator progressively to carry out deeply by the way of human-computer interaction interface exchanges with operator Diagnosis, finally positions failure cause.
