specific Embodiment approach

[0034] It mainly includes five parts: computer, power supply, test fixture, test motherboard, and the motherboard to be tested. The power supply is 220V AC input, the highest 30V / 3A DC output adjustable power supply, and the typical output voltage is set to 12V. It can be adjusted according to the power supply voltage of the motherboard under test. The computer configuration requirements are: the main frequency of the processor is above 2GHz, the memory is above 1GB, and the hardware capacity is above 80GB. The typical loading system is Microsoft Windows XP / Windows 7. The interior of the test motherboard is designed around the core processor NXP LPC4357, supplemented by several integrated circuits. The test fixture is a structural fixture specially made for different motherboards to be tested. Its function is to connect the test resources that can be provided on the motherboard to the functional modules that need to be tested on the motherboard to be tested through wiring + p...

Abstract

The invention provides an automatic hardware test system and relates to the technical field of electronic device detection. The automation hardware test system comprises: a power source, a computer device, a test clamp and a test motherboard. The power source is connected to a tested motherboard. The computer device is connected to the test motherboard. The test clamp is connected to the test motherboard and the tested motherboard. The test clamp is a structure clamp customized according to the tested motherboard, and connects a hardware resource provided by the test motherboard to a functional module required to be tested on the tested motherboard by a wire and/or a probe. A variety of hardware test interfaces and related circuits are integrated into the test motherboard. A test process requires almost no manual intervention. The integrated circuit module replaces a complicated instrument to simplify the test model. Test results are determined and recorded by the computer and the processor, thereby avoiding a risk caused by human error while saving a lot of manpower.

Description

technical field [0001] The invention relates to the technical field of electronic device detection, in particular to an automatic hardware testing system. Background technique [0002] Traditional hardware testing methods are generally based on targeted functional testing. For example, if you need to measure voltage, workers use multimeters and other instruments to measure voltage; if you need to test the serial port, you need to connect the serial port to the computer through RS232. Manually input commands or Check the connection status; you need to test the audio, you need to measure the signal through an oscilloscope, or judge by pronunciation and hearing. This kind of test process requires more discrete instruments and equipment, and also requires more manual operations, and the test results also need manual judgment, which is highly dependent on testers. Therefore, how to improve the efficiency of hardware testing has become an urgent technical problem to be solved. ...
