Automobile diagnosis communication module data transceiving parallel processing method

Abstract

The invention provides an automobile diagnosis communication module data transceiving parallel processing method. The method comprises steps that, a, a diagnosis communication module starts and realizes initialization operation; b, receiving sub threads or interruption service of request data of a host computer starts; c, a main thread of the diagnosis communication module is detected to receive a request mark of the host computer; d, the sub threads or the interruption service communicating with a diagnosis bus start; and e, a to-be-uploaded reply request mark is detected by the main thread of the diagnosis communication module, and reply data is transmitted by the diagnosis communication module to the host computer. According to the automobile diagnosis communication module data transceiving parallel processing method, the sub threads or the interruption service is opened on the diagnosis communication module on diagnosis equipment, so data interaction parallel processing is realized, the speed and efficiency of data interaction are improved through the method, and occasions, such as dynamic data flow and long time data monitoring requiring rapid and large-quantity bus data and calculation perform better.

Description

technical field [0001] The invention relates to the technical field of automobile diagnosis, in particular to a method for parallel processing of sending and receiving data of an automobile diagnosis communication module. Background technique [0002] Vehicle fault diagnosis equipment usually consists of upper computer diagnostic function software and lower computer diagnostic communication module. The upper computer mainly implements user operation, display, vehicle data analysis and displays specific diagnostic functions to the user; the lower computer diagnostic communication module is the data channel between the upper computer and the vehicle diagnostic bus, and it is responsible for receiving instructions from the upper computer, analyzing and executing them. command, and is responsible for data interaction with the vehicle diagnostic bus, and uploading relevant data to the host computer. [0003] With the increasing number and complexity of electronic control systems...

AI Technical Summary

Problems solved by technology

[0004] On the vehicle diagnostic communication module in the existing diagnostic equipment, in the process of serial data interaction mode, the diagnostic communication module cannot communicate with the vehicle diagnostic bus when exchanging data with the upper computer, but exchanges commands with the vehicle diagnostic bus , can not communicate with the host computer

This method is fully competent when processing a small amount of low-speed data, but it does not perform well in high-speed, large-scale data processing applications.
