[0066] In the above scheme, the first standard interface 201 is a PIN6 / 14 interface, and the second standard interface 202 is a PIN3 / 11 interface, so that the first standard interface 201 and the second standard interface 202 can match the pins of most network analysis devices, thereby enabling direct connection communication with the CAN network analysis device.

[0067] In some other embodiments, referring to Figure 1 , the plurality of input interfaces 110 include a first input interface 111 and a second input interface 112, which can be understood as respectively transmitting messages.

[0068] The first input interface 111 and the second input interface 112 can simultaneously transmit messages, or alternatively, the first input interface 111 and the second input interface 112 can transmit messages.

[0070] The first input interface 111 is connected to the first standard interface 201 of the first output terminal 210, which can be understood as outputting messages from the first input interface 111 through the first standard interface 201, thereby enabling message acquisition from the first input interface 111 when the CAN channel connected to the first input interface 111 changes, improving the convenience of use.

[0071] The second input interface 112 is connected to the second standard interface 202 of the first output terminal 210, which can be understood as outputting messages from the second input interface 112 through the second standard interface 202, thereby enabling message acquisition from the second input interface 112 when the CAN channel connected to the second input interface 112 changes, improving the convenience of use.

[0072] In addition, the first standard interface 201 and the second standard interface 202 of the first output terminal 210 can simultaneously output messages, so that the first output terminal 210 can simultaneously output messages from the first input interface 111 and the second input interface 112, thereby improving the convenience of use.

[0073] In some other embodiments, referring to Figure 1 and Figure 3 , the second input interface 112 is a PIN6 / 14 interface.

[0074] In the above scheme, since the second input interface 112 is a PIN6 / 14 interface, the second input interface 112 can match the pin definition of most network analysis devices, and when the CAN channel corresponding to the second input interface 112 needs to be detected separately, the corresponding CAN channel can be directly detected, which helps to improve the detection efficiency.

[0075] In some other embodiments, referring to Figure 1 , the plurality of input interfaces 110 include a third input interface 113 and a fourth input interface 114. It can be understood that the third input interface 113 and the fourth input interface 114 can respectively function to transmit the message.

[0076] The third input interface 113 and the fourth input interface 114 can simultaneously transmit the message, or the third input interface 113 and the fourth input interface 114 can alternatively transmit the message.

[0077] The plurality of output terminals 200 include a second output terminal 220. It can be understood that the second output terminal 220 can function to output the message, and the second output terminal 220 can output the message of different input interfaces 110 with the first output terminal 210 respectively.

[0078] Further, the first output terminal 210 and the second output terminal 220 can simultaneously or non-simultaneously output the message, and the first output terminal 210 and the second output terminal 220 both have a first standard interface 201 and a second standard interface 202.

It can be understood that the message of the third input interface 113 can be output through the first standard interface 201, so that when the CAN channel connected with the third input interface 113 changes, the message acquisition of the third input interface 113 can still be realized, improving the use convenience.

[0081] The fourth input interface 114 is connected with the second standard interface 202 of the second output terminal 220. It can be understood that the message of the fourth input interface 114 can be output through the second standard interface 202, so that when the CAN channel connected with the fourth input interface 114 changes, the message acquisition of the fourth input interface 114 can still be realized, improving the use convenience.

[0082] In addition, the first standard interface 201 and the second standard interface 202 of the second output end 220 can output the messages simultaneously, so that the second output end 220 can output the messages of the third input interface 113 and the fourth input interface 114 simultaneously, thereby improving the convenience of use.

[0083] In some other embodiments, referring to Figure 1 and Figure 3 the third input interface 113 is a PIN3 / 11 interface.

[0084] In the above scheme, since the third input interface 113 is a PIN3 / 11 interface, the third input interface 113 can match the pin definition of most network analysis devices, and when it is necessary to detect the CAN channel corresponding to the third input interface 113 separately, the corresponding CAN channel can be directly detected, which helps to improve the detection efficiency.

[0085] In some other embodiments, referring to Figure 1 and Figure 2 the plurality of input interfaces 110 include a fifth input interface 115, and it can be understood that the fifth input interface 115 can individually serve the function of transmitting messages, so as to obtain the messages of the CAN channel corresponding to the fifth input interface 115.

[0086] The plurality of output ends 200 include a third output end 230, and it can be understood that the third output end 230 can provide more output interfaces, which not only facilitates the corresponding output of the messages of the plurality of input interfaces 110 respectively, but also helps to increase the ports for simultaneous output, thereby helping to improve the detection efficiency.

[0087] The third output end 230 also has the first standard interface 201 and the second standard interface 202, so as to realize the output of one CAN or two CANs.

[0088] The first input interface 111, the second input interface 112 and the fifth input interface 115 are alternatively connected to the second standard interface 202 of the third output end 230 through the first switch 310, and it can be understood that the second standard interface 202 of the third output end 230 can be connected to one of the first input interface 111, the second input interface 112 and the fifth input interface 115 at this time, so as to output the messages of the corresponding input interface 110.

[0089] The third input interface 113, the fourth input interface 114 and the fifth input interface 115 are alternatively connected to the first standard interface 201 of the third output end 230 through the second switch 320, and it can be understood that the first standard interface 201 of the third output end 230 can be connected to one of the third input interface 113, the fourth input interface 114 and the fifth input interface 115 at this time, so as to output the messages of the corresponding input interface 110.

[0090] In addition, the first standard interface 201 and the second standard interface 202 of the third output end 230 can simultaneously output the message, so as to simultaneously detect the messages of the two input interfaces 110.

[0091] At this time, the first standard interface 201 is in communication with one of the third input interface 113, the fourth input interface 114 and the fifth input interface 115, and the second standard interface 202 is in communication with one of the first input interface 111, the second input interface 112 and the fifth input interface 115.

[0092] Therefore, the simultaneous detection of the first input interface 111 and the third input interface 113, the simultaneous detection of the first input interface 111 and the fourth input interface 114, the simultaneous detection of the first input interface 111 and the fifth input interface 115, the simultaneous detection of the second input interface 112 and the third input interface 113, the simultaneous detection of the second input interface 112 and the fourth input interface 114, the simultaneous detection of the second input interface 112 and the fifth input interface 115, the simultaneous detection of the third input interface 113 and the fourth input interface 114, and the simultaneous detection of the third input interface 113 and the fifth input interface 115 can be realized.
