System for automatically testing computer mainboard

Abstract

The invention discloses a system for automatically testing a computer mainboard. The system comprises a signal processing module, a display unit, a sending module, a receiving conversion module and a mainboard to be tested; the signal processing module is connected with the display unit, the sending module and the receiving conversion module respectively; the output end of the signal processing module is connected with the display unit; the input end of the sending module is connected with the signal processing module, and the output end of the sending module is connected with the mainboard to be tested; the input end of the receiving conversion module is connected with the mainboard to be tested, and the output end of the receiving conversion module is connected with the signal processing module; the computer mainboard comprises a keyboard part, an audio signal part, a plurality of universal serial bus (USB) interfaces and a video signal part; and a plurality of video signals of the video signal part are uniformly converted into standard video graphics array (VGA) signals for transmission. In the system, the quality of the mainboard to be tested is directly analyzed at a signal end; and the system totally substitutes for manual judgment and test of workers, so the test efficiency is improved greatly, and the accuracy is high.

Description

technical field [0001] The invention relates to the field of computer mainboard function testing, in particular to an automatic testing system for computer mainboard function testing. Background technique [0002] The principle of traditional computer motherboard testing is to use interfaces between modules. For example, after connecting all peripheral circuits such as hard disk, memory, CPU, keyboard, and display to the motherboard, turn on the computer to actually run various test programs, which is equivalent to simulating The actual working conditions of the notebook. The current design is the most direct and intuitive test method, but it has a lot of disadvantages, such as the test takes a lot of time, and the actual insertion will take up a lot of time during the whole test process, and each fixture factory produces There are various test fixture structures, lack of unified standardization, and the operators also lack unified operating standards when they work. Each m...

The current design is the most direct and intuitive test method, but it has a lot of disadvantages, such as the test takes a lot of time, and the actual insertion will take up a lot of time during the whole test process, and each fixture factory produces There are various test fixture structures, lack of unified standardization, and the operators also lack unified operating standards when they work. Each model must have standard operating instructions and training, which brings great impact to the management of factory operators. Come to trouble, and at the same time, there are certain requirements for the operators

[0003] In addition, it is inevitable that the interface will be damaged during the actual difference of each interface, so that some interfaces become consumables for testing, which will inevitably increase the cost of testing; in addition, there are test operators, and a fixture must be equipped with One operator, this labor-intensive testing method also makes the factory very passive under the current shortage of labor force, which will consume a lot of manpower and material resources of the factory
