Embodiment Construction
[0016] In order to facilitate the understanding of those skilled in the art, the present invention will be further described in detail below with reference to the drawings and embodiments.
[0017] Such as figure 1 As shown, the multi-functional adapter box disclosed by the present invention is composed of five parts: a main control unit, a MAX232 communication module, a CAN transceiver, a voltage stabilizing circuit and a power supply. The power supply and the voltage stabilizing circuit are used for the power supply of the other three parts. The CAN transceiver is used to realize the communication of the physical layer of the CAN and LIN protocols. The CAN transceiver uses a CAN transceiver chip, which is connected to the communication transfer box through two pins of CAN-H and CAN-L. The MAX232 communication module is used to realize the serial communication between the upper computer and the main control unit based on a custom protocol. The upper computer needs to be conn...
