Method for testing power performance indexes

Abstract

The invention discloses a method for testing power performance indexes, particularly relates to intelligent instrument control technology and belongs to the technical field of intelligent control systems. The method includes that electronic engineers compile a GPIB (general purpose interface bus) instruction group card of performance indexes required by fault testing for a circuit board; program development personnel build a database for storing each GPIB instruction group required by testing for the corresponding performance index; the instruction groups are inputted into the database via a user interface; and programmers write an intelligent GPIB instruction interpreter. Software development personnel do not need to know specific electronic and electrical professional knowledge of the tested performance indexes, and accordingly requirements on comprehensive abilities of various personnel in a system are greatly lowered. In addition, severe shortcomings that GPIB instructions are directly bound with programming languages traditionally, programs need to be modified even if the used GPIB instructions or parameters are changed subtly, and software development personnel and electronic and electrical engineers need to work together are overcome.

Description

technical field [0001] The invention relates to a power supply performance index testing method, in particular to an intelligent instrument control technology, which belongs to the technical field of intelligent control systems. Background technique [0002] With the continuous development of computer applications, computer technology has been well applied in the automatic test of system faults. There are many types of power supplies for radar systems. After a fault occurs, it is difficult for ordinary maintenance personnel to solve the problem. Using a computer for power fault testing is mainly First establish a fault expert knowledge base based on the principle of the power supply. After the power supply fails, use computer software to perform auxiliary tests according to the process of the fault expert knowledge base to judge and locate the fault. [0003] The establishment of a fault expert knowledge base (including fault tree) requires not only theoretical analysis but ...

Problems solved by technology

When the traditional computer software develops and controls the test bench of the GPIB (General Purpose Interfaces Bus) bus, because there are many GPIB commands and the parameters are uncertain, the old system design method is to write the GPIB commands, parameters and the flow sequence of GPIB command execution in the specific In the program code, the serious disadvantage of the close combination of the function implementation of the GPIB instruction and the program of the process implementation is: as long as there is a slight change in the GPIB instructions and parameters used in the test, the program must be modified. Software developers and electronic and electrical engineers must simultaneously Working together, relying on developers with strong comprehensive ability, even if object-oriented technology is introduced, it is only a simple encapsulation of GPIB basic functions
