Embodiment Construction

[0037] A preferred embodiment will be given below, and the present invention will be described more clearly and completely in conjunction with the accompanying drawings.

[0038] This embodiment provides a refreshing script parsing system. refer to figure 2 , the refresh script parsing system includes a script parser 1 and a virtual machine 2 . The script parser 1 is used to analyze the refresh script according to the preset grammatical structure to generate target instructions; the virtual machine 2 is used to execute the refresh process according to the target instructions, and output a refresh log.

[0039] During specific implementation, the refresh script parsing system is embedded in the hosting environment 3 . In some optional embodiments, the host environment 3 is a diagnostic instrument. In some other optional implementation manners, the host environment 3 is an OTA Master.

[0040] The host environment 3 provides a file system interface 301 and a diagnostic comm...

Abstract

The invention provides a refreshing script analysis system. The system comprises a script analyzer and a virtual machine, wherein the script analyzer is used for analyzing the refreshing script according to a preset grammar structure to generate a target instruction; and the virtual machine is used for executing a refreshing process according to the target instruction and outputting a refreshing log. According to the method, the efficiency of refreshing script analysis is improved, the refreshing script analysis system processes the flow and logic of the diagnosis application in a centralized manner, a user does not need to care about a communication medium and a transmission layer protocol at the bottom layer, and transplantation among different diagnosis protocols is facilitated.

Description

technical field [0001] The invention relates to the technical field of refresh script analysis, in particular to a refresh script analysis system. Background technique [0002] In recent years, CAN (Controller Area Network, controller area network) / CAN-FD (Flexible Data-Rate, variable rate), Ethernet and other new communication protocols are more and more used in automobiles. With the development of intelligent networked vehicles, the OBD (On Board Diagnostics, a detection system extended for vehicle fault diagnosis) diagnosis / refresh and OTA (Over-the-Air) upgrade of the in-vehicle controller have already Become the basic function of the car. [0003] refer to figure 1 , a diagnostic instrument (for example, an OBD diagnostic instrument) and an OTAMaster (master device) respectively communicate with several in-vehicle controllers. These in-vehicle controllers can be used as CAN / CAN-FD nodes, Ethernet nodes, etc. At present, the OBD diagnostic instrument and OTAMaster (m...
