Embodiment Construction

[0011] refer to figure 1 , the TV circuit board circuit detection system in an embodiment includes an ARC detection device 110 and an HDMI port 130 , and the ARC detection device 110 is connected to the TV circuit board 200 through the HDMI port 130 .

[0012] The ARC detection device 110 is used to receive the return audio signal output by the TV circuit board 200 through the HDMI port 130, obtain the parameter value according to the return audio signal, and judge whether the return audio signal is valid according to the parameter value, and when the return audio signal is valid Send preset line normal information, and send preset line abnormal information when the return audio signal is invalid.

[0013] After receiving the audio signal, the TV circuit board 200 with the ARC function can implement the audio return through the ARC line. The return audio signal refers to the signal output by the TV circuit board 200 after receiving the audio signal. Since the returned audio ...

Abstract

The invention relates to a television circuit board circuit detection system, comprising an ARC (audio return channel) detection device and an HDMI (high definition multimedia interface); the ARC detection device is connected with a television circuit board through the HDMI and is used for receiving a returned audio signal output by the television circuit board through the HDMI, acquiring parameter values according to the returned audio signal, and judging whether the returned audio signal is valid or not according to the parameter values, preset line normality information is transmitted if the returned audio signal is valid, and preset line abnormality information is transmitted if the returned audio signal is not valid; therefore, returned audio signals can be analyzed according to the parameter values to acquire line detection results, there is no need for playing sound with a sound apparatus, artificial misjudgment is avoided, and the system is simple in structure and high in detection accuracy.

Description

technical field [0001] The invention relates to the technical field of equipment detection, in particular to a television circuit board circuit detection system. Background technique [0002] After the TV circuit board is produced, it is usually necessary to perform a circuit test to detect whether the signal connectivity of each circuit is normal. For TV circuit boards with HDMI (High Definition Multimedia Interface) port and ARC (Audio Return Channel) function, the ARC line is independent, so the connectivity of the ARC line needs to be tested separately. [0003] The traditional method of testing the connectivity of ARC lines is to use audio equipment that supports the ARC function to test. The audio equipment is connected to the TV circuit board through an HDMI cable, and the TV is adjusted to enable the ARC function; if the audio equipment can emit correct sounds, it means ARC The connection of the line is normal, otherwise, further check the connectivity of the ARC li...
