产品概述

OBD communication board is a high-performance automotive bus diagnostic equipment independently developed by Beijing Taiyuanxiang Technology Co., Ltd. The device is connected to the vehicle through the OBD interface. It supports 6 channels of can/CANFD bus, 1 channel of K-line and 1 channel of DOIP bus data acquisition and diagnosis. It adopts industrial-grade Bluetooth wireless communication. At the same time, it supports Bluetooth fast switching RS232 wired communication mode, adapts a complete vehicle offline solution, and can support most automobile bus communication on the market.

The board is designed for the off-line electrical inspection station of the vehicle: After the vehicle is driven into the station, the operator inserts the diagnostic head into the vehicle OBD interface, and the board establishes a data link with the host computer through Bluetooth or serial port to complete the collection, writing and fault diagnosis of the vehicle bus data; in the accompanying station scenario, there is no need to drag the cable, and the wireless and wired can be automatically switched to ensure the stability of the beat.
