Thus, it should be noted that the main board 110 is a core component of the TV100, and all signals of the TV100 are processed, transmitted and received on the main board 110; the display module 120 plays a role in displaying, when the screen 125 needs to be started to work, the main board 110 outputs a relevant signal to the T-CON board 122 through the V-1 line 121, the T-CON board 122 outputs a signal to the SOC board 124 through the FFC line 123 after receiving the signal, and the SOC board 124 can start the screen 125 to light up to work to play audio and video; the WiFi module 130 is used for transceiving wireless signals, so that the TV100 has a function of accessing the internet.

It should be noted that the connection between the signal generating device 200 and the WiFi module 130 is a wireless connection, and not a wired connection.
Referring to fig. 2, in order to better understand the specific working principle of the apparatus 10 for searching for TV-to-WiFi module interference source, the following discloses a method for searching for TV-to-WiFi module interference source based on the apparatus 10, including the following steps:
step S01, the screen 125 is turned off, the signal generating device 200 is used to obtain the sensitivity value of the WiFi module 130 in the current state, and a reference sensitivity interval is obtained according to the preset deviation value, where the reference sensitivity interval is [ current sensitivity value-preset deviation value, current sensitivity value + preset deviation value ].
Therefore, it should be noted that, the screen 125 is turned off, that is, the display module 120 is not started, the TV100 is only turned on a small number of functions, the signal generating device 200 is used to obtain the sensitivity value of the WiFi module 130 in the current state, the detected sensitivity value of the WiFi module 130 is the sensitivity value without being affected by the interference source, a reference sensitivity interval is obtained by calculation according to the preset deviation value, the reference sensitivity interval is [ the current sensitivity value-the preset deviation value, the current sensitivity value + the preset deviation value ], and the interference source to the WiFi module 130 in the TV10 is located by using the reference sensitivity interval.
It should be noted that the preset deviation value is 6dbm, and of course, the preset deviation value can be flexibly set according to actual conditions.
Step S02, the screen 125 is lighted, the signal generating device 200 is used for obtaining the current sensitivity value of the WiFi module, if the current sensitivity value falls into the reference sensitivity interval, it is judged that no interference source exists in the display module 120, and the step S04 is executed; otherwise, step S03 is executed.
Thus, it should be noted that, after the reference sensitivity interval is obtained, the screen 125 is lit, at this time, the display module 120 starts to operate, the display module 120 starts a part of functions, at this time, the V-1 line 121, the T-CON board 122, the FFC line 123, the SOC board 124 and the screen 125 all start to operate, at this time, the signal generating device 200 is used to obtain the current sensitivity value of the WiFi module 130, if the current sensitivity value falls within the reference sensitivity interval, it is determined that no interference source exists in the display module 120, because the obtained current sensitivity value still falls within the reference sensitivity interval, that is, the V-1 line 121, the T-CON board 122, the FFC line 123, the SOC board 124 and the screen 125 do not have any interference on the WiFi module 130; if the current sensitivity value does not fall within the reference sensitivity interval, step S03 is executed.
Step S03, at least one of the V-1 line 121, the T-CON board 122, the FFC line 123, the SOC board 124 and the screen 125 is shielded, the current sensitivity value of the WiFi module 130 is obtained by the signal generating device 200, if the current sensitivity value falls within the reference sensitivity interval, the step S03 is repeatedly executed until the current sensitivity value does not fall within the reference sensitivity interval any more, and all interference sources in the display module 120 are positioned.
Thus, it should be noted that if the current sensitivity value does not fall within the reference sensitivity interval, it is determined that an interference source to the WiFi module 130 exists in the display module 120, and at this time, it is necessary to locate which portion of the display module 120 generates interference to the WiFi module 130. In order to locate the interference source in the display module 120 most rapidly, four of the V-1 line 121, the T-CON plate 122, the FFC line 123, the SOC plate 124 and the screen 125 are shielded, for example, the four of the V-1 line 121, the T-CON plate 122, the FFC line 123 and the SOC plate 124 are shielded first, the screen 125 is not shielded, the signal generating device 200 is used to obtain the current sensitivity value of the WiFi module 130, if the current sensitivity value falls within the reference sensitivity range, it is determined that the screen 125 is not the interference source, the interference source is among the four of the V-1 line 121, the T-CON plate 122, the FFC line 123 and the SOC plate 124, then the V-1 line 121, the T-CON plate 122, the FFC line 123 and the screen 125 are shielded, the SOC plate 124 is not shielded, the signal generating device 200 is used to obtain the current sensitivity value of the WiFi module 130, if the current sensitivity value does not fall within the reference sensitivity interval, SOC board 124 is determined to be the interference source.
It should be noted that, after the SOC board 124 is determined to be the interference source, the step S03 is further executed until the current sensitivity value of the WiFi module 130 is obtained by the signal generating device 200 without performing the shielding process on the V-1 line 121, the T-CON board 122, the FFC line 123, the SOC board 124 and the screen 125, and it is determined whether the current sensitivity value falls within the reference sensitivity interval, so that the step S04 may be executed.
Step S04, lighting the screen 125 and playing an audio/video, acquiring a current sensitivity value of the WiFi module 130 by using the signal generating device 200, and if the current sensitivity value falls within a reference sensitivity interval, determining that the main board 110 does not have interference; otherwise, the main board 110 is determined as an interference source.
Thus, it should be noted that, after the interference source in the display module 120 is confirmed, the screen 125 is lit and an audio/video is played, at this time, the main board 110 operates at a high speed, it needs to be determined that the normal operation of the WiFi module 130 will not be affected by the high-speed operation of the main board 110, and similarly, the signal generating device 200 is used to obtain the current sensitivity value of the WiFi module 130, and if the current sensitivity value falls within the reference sensitivity interval, it is determined that the main board 110 does not have interference; otherwise, the main board 110 is determined as an interference source. Through the steps S01 to S04, the interference sources in the TV100 can be quickly located, the interference sources that affect the normal operation of the WiFi module 130 can be found out, and then the interference sources are shielded, for example, a shielding cover is added to the interference sources to prevent the interference sources from affecting the normal operation of the WiFi module 130.
According to the device and the method for searching the interference source of the TV to the WiFi module, the TV, the WiFi module and the signal generating device are arranged, the signal generating device is used for obtaining the sensitivity value of the WiFi module in the current state under the screen closing state, the reference sensitivity interval is obtained according to the preset deviation value, and the interference source of the TV to the WiFi module is positioned by using the reference sensitivity interval.
The above embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
