The invention provides a communication device of an automobile diagnosis system. The communication device includes a first transmission channel and a second transmission channel both of which are connected between a controller and a first connector, a third transmission channel connected between a power source and the first connector, and also a fourth transmission channel connected between the controller and a host computer. The first and second transmission channels are used for isolation between the controller and the first connector, gating control and diagnosis information sending and receiving. One of the first and second transmission channels supplements compatibility for a protocol transceiver of the other transmission channel to match to-be-diagnosed automobiles with different protocols. The third transmission channel is used for providing programmable voltages. The four transmission channel is used for diagnosis information interaction with the host computer. Through adoption of multiple transmission channels, one of the first and second transmission channels supplements compatibility for the protocol transceiver of the other transmission channel to match the to-be-diagnosed automobiles with different protocols.
Description
technical field [0001] The invention relates to the vehicle diagnosis technology, in particular to a communication device of the vehicle diagnosis system. Background technique [0002] With the rapid development of modern automotive electronics technology, the communication protocols of newly added automotive electronic equipment are rapidly updated.
