Abstract

The invention discloses a data processing method, which is applied to a controller local area network, the controller local area network comprises a plurality of sub-interface data queues, and the data processing method can obtain data received by the controller local area network and a data mapping relationship; then, the data type is confirmed according to the data; then, according to the data type and the data mapping relation, an analysis method of the data is confirmed; then, analyzing the data according to the analysis method to obtain analyzed data; and then, according to the data type, sending the analysis data to the sub-interface data queue. And analyzing the data according to the data type and the data mapping relationship, and sending the analyzed data to the corresponding sub-interface data queue, so that the data processing capability of interface software can be improved, and the running speed is accelerated.

Description

technical field [0001] The present application belongs to the technical field of data processing in controller area network, and in particular relates to a data processing method and a data processing device. Background technique [0002] The controller area network (CAN bus) is widely used in special vehicle control due to its high real-time and reliable characteristics. Based on the controller area network, it is necessary to realize the functions of special vehicle status display, human-computer interaction, and motion control. The front-end interface display of the special vehicle monitoring software needs to display the status in real time while aiming at the validity of the data range, time, etc., as well as highlighting / focusing on different working conditions, etc.; the back-end business logic needs to ensure real-time and reliable transmission and reception, processing controller area network Data, and at the same time carry out logical processing for interface disp...
