Problems solved by technology

The existing toolkits are C-based and Python-based, but these toolkits do not strictly distinguish the application layer, network layer, and device driver layer, resulting in poor function expansion and device compatibility
On the other hand, the timing mechanism also depends on the external calling program, making the toolkit more dependent

Embodiment Construction

[0021] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.

[0022] This client general system based on UDS protocol communication of the present invention includes:

[0023] The interface interaction module is used to provide user settings and configurations and deliver them for processing, and display feedback and various error messages;

[0024] The application layer protocol module is connected with the interface interaction module, and is used to encapsulate the information delivered by the interface interaction module into UDS A_PDU format, and collect error information and deliver it to the interface interaction module for processing;

[0025] The network layer protocol module is connected with the application layer protocol module, and is used to organize the UDS A_PDU format into the N_PDU format, and monitor various errors of the network layer;

[0026] Th...

Abstract

The invention relates to a client universal system based on UDS protocol communication, and the system comprises an interface interaction module which is used for providing the setting and configuration of a user, carrying out the delivery processing, and displaying the feedback and various types of error information; an application layer protocol module used for packaging the information delivered by the interface interaction module into a UDS A _ PDU format; a network layer protocol module used for arranging the UDS A _ PDU format into an N _ PDU format; and a CAN equipment driving moduleused for mapping the N _ PDU data to a CAN data frame for transmitting and receiving, and writing the original data into a log. The client universal system based on the UDS protocol communication is adopted; various applications based on the UDS protocol can be rapidly developed in a cross-platform mode, meanwhile, more services and NRC supports of the UDS are added, more CAN devices can be easilyexpanded, good frame structure type expansion and maintenance of the CAN devices are very rapid, and therefore the application range based on the UDS protocol is wider.

Description

technical field [0001] The invention relates to the computer field, in particular to the field bus communication field, and specifically refers to a general-purpose client system based on UDS protocol communication. Background technique [0002] With the widespread use of fieldbus protocols, there are more and more CAN-based UDS (Unified Diagnostic Services) protocols for parameter calibration, fault diagnosis, offline detection, and program flashing. It greatly facilitates the development and maintenance of vehicle-mounted products and related tools. [0003] Tool software needs to be customized and developed according to customer needs. The operating environment, CAN equipment, and required services are different, but the standard protocol part is the same, which requires a common development software toolkit. The existing toolkits are C-based and Python-based, but these toolkits do not strictly distinguish the application layer, network layer, and device driver layer, re...
