Audio-visual chip detection system and method

Abstract

The invention discloses an audio-visual chip automatic detection system, which comprises a storage device, an audio-visual chip slot, an image capture card, a microprocessor, a communication port and a mechanical arm. In the audio-visual chip automatic detection system, audio-visual materials are stored in the storage device of a main board; the audio-visual chip slot is arranged on the main board for installation of a sample audio-visual chip and an audio-visual chip to be detected; the audio-visual materials are displayed and first audio-visual data is acquired by the sample audio-visual chip; the audio-visual chip to be detected is used for replacing the sample audio-visual chip to play the audio-visual materials and acquire second audio-visual data; the second audio-visual data and the first audio-visual data are compared so as to judge whether the audio-visual chip to be detected is qualified or not; and a control signal is output according to comparison results, and the mechanical arm is controlled by the communication port so as to place the audio-visual chip to be detected at a preset position. The invention further provides an audio-visual chip automatic detection method.

Description

technical field [0001] The invention relates to a detection system and method, in particular to an audio-visual chip detection system and method. Background technique [0002] The traditional audio-visual chip inspection system uses an audio-visual player, such as a DVD player, to play the audio-visual data stored in a disc. The specific process is to first install a qualified audio-visual chip as a sample audio-visual chip in the audio-visual player Play the audio-visual data in the disc, and transmit the audio-visual signal in the form of audio resolution, video resolution and frame rate to a computer for storage. Then, replace the sample audio-visual chip in the audio-visual player with an audio-visual chip to be tested to play the audio-visual data in the disc, and the audio-visual signal that will be played is also in the audio-visual resolution, video resolution and frame rate, etc. The form is transferred to the computer and stored. Finally, the computer compares th...

Problems solved by technology

However, after the traditional audio-visual chip detection system completes the detection of an audio-visual chip to be tested, it is necessary to wait for the audio-visual player to completely stop playing the audio-visual data in the disc before replacing another audio-visual chip to be tested, and the audio-visual player needs to be restarted. start to play audiovisual material for detection, so stopping and restarting wastes detection time
