Embodiment 1

[0025] see figure 2 The parallel data interaction process of the vehicle diagnostic communication module of the present invention is shown, including:

[0026] Step 201: diagnosing the start-up of the communication module and initializing the operation;

[0027] Specifically, two sub-threads are set in the diagnostic communication module, which are respectively used to receive request data from the upper computer and exchange information with vehicle diagnostic bus data, while the main thread of the diagnostic communication module is used to check whether there is a request from the upper computer. Processing, and whether there is data to be uploaded to the host computer.

[0028] Step 202: Start the sub-thread for receiving the data requested by the host computer;

[0029] Specifically, the host computer sends a data request, and the sub-thread of the host computer requesting data in the diagnosis communication module receives the request data from the host computer, saves...

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...
