Problems solved by technology

[0005] Currently analyzing CAN data, combined with DBC and CANOE, the analysis effect is obvious and convenient. However, due to the high price and high cost of CANOE, it is impossible for R&D, after-sales and experimental personnel to equip each person with a CANOE. The meritorious CANTEST software is easy to get stuck when parsing DBC

Embodiment Construction

[0036] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. Such as figure 1 As shown, the method of the present invention includes the following steps:

[0037] Step 1: Process and parse the DBC file through LABVIEW:

[0038] 11. Import the DBC file;

[0039] 12. Separate all IDs first: read the DBC file text line data information line by line, compare each line with BO_, and after the comparison is consistent, treat the data immediately after it as the ID, and record the serial number and ID of this line Serial number

[0040] 13. Analyze the variable names under each ID separately, compare each line with SG_, and compare the key symbols':','|','@','(',',',' )','[',']' to judge, and separate variable name, start bit, data length, data format, data type, precision, and offset.

[0041] Step 2: Correspond to the data separated in Step 1:

[0042] 21. Combine the variable name with the following data information to cr...

Abstract

The invention discloses a method for parsing a DBC analysis message based on LABVEIW. By processing and parsing a DBC file through the LABVEIW, ID, namely CAN message frame address, variable name, start bit, length, data format, data type, accuracy and offset can be obtained by decomposing; the separated data is in one-to-one correspondence; and a read-in variable is parsed in real time. The method has the advantages that the DBC file can be effectively utilized, the method can be widely applied to after-sales and experimental workers, the equipment cost is reduced, and information on a CAN line can be interpreted effectively.

Description

Technical field [0001] The invention relates to a method for analyzing DBC analysis messages based on LABVEIW, which belongs to the technical field of automatic control. Background technique [0002] With the wide application of CAN bus technology in automobiles. Real-time monitoring of ECU working condition data is an important task in the process of automobile development and testing. The DBC file is issued by Vector. It is used to describe the information of each logical node in a single CAN network. Based on this file, it can be developed to monitor or analyze the operating status of all logical nodes in the CAN network, and it can also be targeted. ECU communication application software. [0003] The patent application with publication number CN107453845A discloses a response confirmation method and device. This application can solve the problem of waste of resources caused by sending response messages in message mode. In the prior art, the response message is also in messag...
