Embodiment 1
[0052] Such as figure 1 As shown, in order to solve the above problems, the present embodiment proposes a method for realizing multiple car audio coding based on the CAN bus, which mainly includes the following steps:
[0053] S1, the test tool is connected to different products under test through the CAN bus, and broadcasts coded commands with different node codes to different products under test;
[0054] S2, any product to be tested receives any coding command, obtains the corresponding node code, and responds to the test tool according to the node code;
[0055] S3, the test tool sends an operation command with any node code and operation information;
[0056] S4. After the corresponding product under test receives and executes the operation command, it responds to the test tool.
[0057]Preferably but not limited, when the product under test responds to the test tool in step S2, it will respond with a response coded command related to the coded command, for example, the...
Embodiment 2
[0089] Such as figure 2 As shown, the present embodiment proposes a system based on the CAN bus to realize multiple car audio encodings, mainly including a power supply 10, a test tool 20 and a plurality of products to be tested 30; Each product under test 30 is electrically connected; the test tool 20 is also connected to multiple products under test 30 through the CAN bus.
[0090] Wherein, the power supply 10 is used to supply power to different products under test 30 respectively according to the control of the test tool 20; the test tool 20 is used to send coded commands with different node codes to the product under test 30; the product under test 30, It is used to receive any coding command, and marks itself to be coded as the node code corresponding to the current coding command; it is also used to feed back the node code to the test tool 20; the test tool 20 is also used for the operation command of the convenient email node code; to be The test product 30 is used t...
