Problems solved by technology

[0005] 1) The display method of the message is in hexadecimal format. Although it is convenient to view the original data, it cannot observe the change of a certain type of data very well. What the user can observe is the hexadecimal system that jumps one by one characters, and it is difficult to form a direct concept of the message
[0006] 2) It is too specialized, so that users who do not understand the meaning of their data (for example, most non-professionals and some users who do not care about the specific value of the data but care about the change of the data) cannot easily use this tool complete the whole process

Abstract

The present invention discloses a data analysis method of a CAN (Controller Area Network) bus. The data analysis method provided by the invention comprises: obtaining the configuration information of the CAN bus; performing data acquisition through the CAN bus according to the configuration information; acquiring a data type selected by a user; extracting all the first data in accordance with the data type selected by the user from the data acquired by the CAN bus, and performing configuration management of all the first data according to a preset data organization mode, wherein the preset data organization mode includes a data calculation formula; converting the first data to a decimal second data according to the data calculation formula. According to the data analysis method of the CAN bus, each step is mutually independent so that the operation is easy for users, the data acquired by the CAN bus is converted to the significant decimal data so that checking and analysis are more visual and much easier for users, and data and information are stored so as to increase the reusability. The present invention further discloses a data analysis device of a CAN bus.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a CAN bus data analysis method and a CAN bus data analysis device. Background technique [0002] Controller Area Network, referred to as CAN, CAN bus protocol is a standard bus for automotive computer control systems and embedded industrial control LANs, and is one of the most widely used field buses in the world. [0003] The related technology discloses a data collection tool based on the CAN protocol. The data collection tool can complete customizable message collection through settings, wherein the display mode of the message is in hexadecimal format. [0004] The shortcoming that the data acquisition tool based on CAN protocol in the above-mentioned related art exists is: [0005] 1) The display method of the message is in hexadecimal format. Although it is convenient to view the original data, it cannot observe the change of a certain type of data very well. What the...
