Abstract

The invention, which belongs to the technical field of data acquisition, particularly relates to a data acquisition system and method based on a CAN bus and wireless communication. The system comprises a data acquisition unit and a mobile terminal; and the data acquisition unit is connected with the mobile terminal. The data acquisition unit consists of a microprocessor, a switching unit connectedwith the microprocessor and a wireless communication unit connected with the microprocessor. The data acquisition unit is used for acquiring external CAN bus data, encoding the collected data, and transmitting the encoded data to the mobile terminal wirelessly; and the mobile terminal is used for displaying the received data, analyzing the displayed data and storing the analyzed data. Therefore,problems that traditional wired CAN data collection is inconvenient, and a mobile terminal is troublesome to maintain are solved; CAN data collection is conducted in a wireless mode instead of a traditional wired mode; and a problem that the mobile terminal analyzes data is solved in a DBC loading mode.

Description

technical field [0001] The invention belongs to the technical field of data acquisition, and in particular relates to a data acquisition system and method based on CAN bus and wireless communication. Background technique [0002] At present, in the automotive communication and related industries, the CAN bus data acquisition tools mainly use VECTOR, ZLGCAN, KVASER, etc., among which even the products with high cost performance cost thousands of dollars, and more than ten thousand. At the same time, CAN data acquisition and analysis requires supporting PC client software, and laptops have also become one of the necessary test tools. For enterprises in the automotive field, after-sales personnel generally need to have the ability to collect and analyze messages. High equipment costs and training for the use of supporting software have brought certain economic pressures to enterprises. [0003] At the same time, some products with CAN data wireless collection function generall...
