Two, three, four, five, six, etc. may be included, and the editable detection sequence is adjusted by editing the detection sequence of the transmission channels to be detected. The flexible application of detection is convenient. The transmission channel to be detected and the next transmission channel to be detected do not imply a sequencing meaning, and are only used for distinguishing different transmission channels to be detected, such as ATV, AV, YPBPR.
Step S200: and acquiring image information of the transmission channel to be detected.
Specifically, referring to fig. 2, the step S200 includes:
step S201: switching a transmission channel to be detected;
when the detection is carried out for the first time, the detection channel is switched to the transmission channel to be detected according to the configuration (DTV/ATV/AV/YPBPR/VGA/HDMI/… …) and the sequence of the transmission channel in the configuration file, and the automatic detection of the input channels one by one is started. The transmission channel to be detected is a transmission channel to be detected with the first detection sequence included in the configuration file information, and a specific channel represented by the transmission channel to be detected can be set according to actual requirements and can be any channel of ATV, AV, and ypbpr.
Step S202: and intercepting the display image of the television based on the transmission channel to be detected as the image information.
Specifically, the existing smart television has a screen capture function, and after the transmission channel to be detected is switched to and is waited for 1-3 seconds to ensure that the signal output is stable, the smart television is controlled to image information through an automatic detection function module. In the technical scheme of the invention, the image information can be the image information displayed on the display screen of the television, and also can be the image information which is decoded by the main chip of the SKD board of the television and is not displayed on the display screen. The television input needs to be decoded by a chip and then is converted into an LVDS/VB1 signal to be transmitted to a screen for display. The image signal directly captured from the chip can effectively avoid the difference of final display on the television screen caused by the transmission process of the LVDS/VB1 signal line and the color difference of the screen.

The detection accuracy is ensured, and the subsequent comparison calculation is convenient.
Step S302: and calculating the matching degree of the image information of the transmission channel to be detected and the preset standard image information based on a template matching algorithm, wherein the matching degree is the comparison value.

Step S303: and acquiring a preset threshold value corresponding to the transmission channel to be detected.
Specifically, in this embodiment, the preset threshold may be set according to an actual result after comparing and calculating images captured by multiple televisions with normal signal transmission channels in advance, for example, two images captured by 100 televisions connected with the same signal (including the same signal input channel and the same signal type and content) are compared with each other, and the comparison method is as described above, if the sum of the comparison difference values is below M, the preset threshold may be tentatively set to M. The preset threshold value can be subsequently adjusted according to an error result after production and practical application, and the error is mainly used for eliminating interference of small display differences caused by transmission errors of resolution error signals of different television displays on a detection result. The preset threshold value is preset in the automatic detection functional module, and calling is realized through the program block.
Step S304: and comparing whether the comparison value is greater than or equal to the preset threshold value to obtain a matching result.
Specifically, a matching result is obtained by comparing whether the comparison value is lower than a preset threshold value, and the detection result is fed back according to the matching result. The matching result is greater than or less than or equal to.
When the comparison value is larger than the preset threshold value, outputting a detection abnormal result of the transmission channel to be detected, and finishing the detection; and when the comparison value is smaller than the preset threshold value, triggering the transmission channel to be detected to be switched to the next transmission channel to be detected.

step S401: and when the matching result is matching, switching the transmission channel to be detected so as to detect the next transmission channel to be detected.
Step S402: and when the matching result is not matched, outputting the abnormal detection result of the transmission channel to be detected.
Specifically, a matching result is obtained by comparing whether the comparison value is lower than a preset threshold value, and the detection result is fed back according to the matching result. The matching result is greater than or less than or equal to.
Specifically, when the comparison value is smaller than the preset threshold, the matching result may be set as a match, and when the comparison value is larger than the preset threshold, the matching result may be set as a match; when the comparison value is equal to the preset threshold value, the matching result may be set to be matched or unmatched according to the actual demand of the product, for example, when the television requires higher display precision or higher quality or the detection channel is frequently used, the matching result when the comparison value is equal to the preset threshold value may be set to be unmatched, and the specific application is not limited.
In this embodiment, when the comparison value is greater than or equal to the preset threshold value, outputting a detection abnormal result of the transmission channel to be detected, and ending the detection; and when the comparison value is smaller than the preset threshold value, triggering the transmission channel to be detected to be switched to the next transmission channel to be detected.

7. An automatic detection device for a television transmission channel, comprising:
an acquisition module: the method comprises the steps of acquiring image information of a transmission channel to be detected;
a matching module: the image information of the transmission channel to be detected is compared with the corresponding preset standard image information to obtain a comparison value; and the comparison value is used for comparing with a corresponding preset threshold value;
a switching module; and the channel to be detected is switched based on the output information of the matching module.
8. The apparatus of claim 7, further comprising:
a configuration module; the configuration module comprises configuration file information, the configuration file information comprises editable configuration of the transmission channel to be detected and editable detection sequence of the transmission channel to be detected, the configuration module is in signal connection with the acquisition module, and the acquisition module further comprises configuration file information used for acquiring the configuration module;
a signal output module: and the detection signal comprises an abnormal detection result and a qualified detection result after the detection of the channel to be detected is finished.
9. An intelligent terminal comprising a memory, and one or more programs, wherein the one or more programs are stored in the memory, and wherein the one or more programs being configured to be executed by the one or more processors comprises instructions for performing the method of any of claims 1-6.
