Problems solved by technology

[0006] In the prior art, if LabVIEW is used to directly call the relevant API (application programming interface) in the existing XNET, the analysis of the CAN message can be completed, but XNET only supports the relevant CAN hardware of NI, and for the commonly used PCAN (PEAK-System Corporation A CAN tool of the company), kvaser CAN (a CAN tool of kvaser company) and other hardware are not compatible; if CANoe (CAN open environment, a bus development environment) equipment is used, the analysis of CAN messages can also be completed, but Its cost is too high, and it is not easy to integrate with the development of the test host computer, which is not conducive to the secondary development of the software

Embodiment 1

[0076] The present invention provides a kind of message parsing method based on LabVIEW, comprises the following steps:

[0077] Step S101, parsing the target DBC file to generate a DBC Information cluster array.

[0078] Step S102, obtaining the physical value of the signal according to the CAN message and the DBC Information cluster array.

[0079] Step S103: Obtain the ID and data array of the CAN message according to the DBC Information cluster array and the physical value of the signal.

[0080] In step S101, call XNET Cluster to obtain DBC file; Call XNET Cluster attribute node, obtain Frames attribute; Circular call XNET Frame attribute node, to obtain ID and Signals attribute, the number of times of cyclic call is the array size of Frames attribute; cyclic call XNET The Signal attribute node gets the attribute of the CAN message, and the number of loop calls is the array size of the Signals attribute; generates a DBCInformation cluster array according to the attribute...

Abstract

The invention discloses a message analysis method and system based on LabVIEW, electronic equipment and a medium. The message analysis method based on LabVIEW comprises the following steps: analyzinga target DBC file to generate a DBC Information cluster array; obtaining a physical quantity value of the signal according to the CAN message and the DBC Information cluster array; and obtaining an IDand a data array of the CAN message according to the DBC Information cluster array and the physical quantity value of the signal. According to the method, the CAN network protocol DBC file is analyzed by using the XNET tool of the LabVIEW, calling and setting of any other control are not needed in the analysis process, the software dependence is low, and the analysis reliability is high. According to the method, the received CAN message and the sent CAN message are analyzed, and the analysis process is bidirectional.

Description

technical field [0001] The invention belongs to the technical field of message analysis, and in particular relates to a message analysis method, system, electronic equipment and medium based on LabVIEW (a program development environment). Background technique [0002] It is necessary to call the .NET (a development platform) container in LabVIEW. Since the .NET container is based on the .NET Framework (a development platform), the compatibility between the computer system and the LabVIEW software must be considered when calling. It is easy to make mistakes when publishing; it is necessary to use the ZEDGraph (a control) control and define the size, but the meaning of the ZEDGraph control and how to define its size are not given in the background technology; the message parsing process is not specified in detail, and the CAN ( Controller Area Network (Controller Area Network) message matching method; only discusses the analysis method of receiving messages from the CAN bus, a...
