In practical applications, both the first main control unit 10 and the switching unit 20 of the device 100 for detecting CI interface of a tv motherboard can be disposed on the production line of the tv motherboard 110. When CI interface detection is required for a plurality of tv motherboards 110 in the production pipeline, the CI card 120 must be repeatedly inserted between a plurality of CI interfaces 111, that is, the CI card 120 needs to be inserted into the CI interfaces 111 a plurality of times, and the CI card 120 needs to be pulled out from the CI interfaces 111 a plurality of times. In order to avoid damage to the physical structure of the CI card 120 for connecting to the CI interface 120 due to multiple plugging operations of the CI card 120, in this embodiment, the adapting unit 20 in the device 100 for detecting the CI interface of the tv motherboard can be used to mount the CI card 120, that is, when detecting the CI interface 111 of the tv motherboard, if the CI card 120 is not damaged or needs to be replaced, the CI card 120 does not need to be taken down from the adapting unit 20, and the adapting unit 20 can also be plugged and connected to the CI interface 111, so that the adapting unit 20 serves as a physical link between the CI interface 111 and the CI card 120, when the connection between the CI card and the CI card is realized, the loss of the CI card 120 in the multiple plugging operations is replaced, thereby protecting the CI card 120 and reducing the cost loss of detecting the CI interface of the tv motherboard.

Referring to fig. 3, an object of the embodiment of the present application is to provide a CI interface signal detection method, and fig. 3 shows a flowchart of implementation of the CI interface signal detection method provided by the embodiment of the present application.
It should be noted that, a CI interface signal detection method in the embodiment of the present application is applied to a television main board with a CI interface, and the television main board is connected to the CI interface detection apparatus 110 of the television main board in the embodiment corresponding to fig. 1. In the CI interface signal detection method in all embodiments of the present application, an execution main body is a television main board, and a control IC, for example, a second main control unit in the previous embodiment, is configured on the television main board. The television main board can determine whether the connection between the CI interface and the television main board is intact according to the detection result of the CI interface signal by executing the CI interface signal detection method, namely, whether the CI interface can be normally used can be determined.

It should be noted that the CI interface is disposed on the television motherboard, and when the television motherboard is in normal use, the CI interface may be connected to the CI card to receive and convert the encrypted digital signal, so as to obtain a television signal capable of being displayed by the television. In order to implement the detection of the CI interface signal, in all embodiments of the present application, when detecting the CI interface signal, the CI card is not directly inserted into the CI interface of the television motherboard, but the CI card is inserted into the switching unit, and then the switching unit carrying the CI card is inserted into the CI interface of the television motherboard, that is, the CI interface of the television motherboard is connected with the CI card through the switching unit.
It should be understood that, since the switching unit is used for carrying the CI card and can be used for plug-in connection with the CI interface of the tv main board, the switching unit is inevitably provided with a slot for carrying the CI card and a connection port for connecting the CI interface of the tv main board.

It should be noted that, because the CI card is a combination of the CAM card and the IC card, and the CI card is used to convert the received encrypted digital signal into a television content signal, the television main board can call the CI interface to communicate with the CI card only in an environment corresponding to the DTV channel, that is, the CI interface signal can be detected only in an environment corresponding to the DTV channel.
As an embodiment of the present application, step S12 may specifically include:
