Embodiment Construction

[0036] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] The scheduling system of diagnostic program among the present invention is based on the embedded system of ARM chip, realizes the loading operation of software with the operating systems such as replacing Linux, ucos, wince, advantage is that real-time performance is high, system startup is fast, has removed the huge operation of loading system troubles.

[0038] see figure 1 , propose an embodiment of the scheduling method of the diagnostic program of the present invention, the scheduling method of the diagnostic program includes the following steps:

[0039] Step S101: After the hardware is initialized, load the FAT file system

[0040] Because it is a bare-metal system, there is no need to load WINCE and other operating systems, so the system starts quickly.

[0041] Step S102: Scan the diagnostic program...

Abstract

The invention discloses a scheduling method and system of a diagnostic program and a diagnostic apparatus. The scheduling method of the diagnostic program includes the steps of scanning the information of diagnostic process after loading FAT file system, and displaying the information of diagnostic process on a screen for users to choose; ensuring a target diagnostic program according to the choice of users; loading the target diagnostic program to an internal storage and scheduling the target diagnostic program. According to the method, the loading of the operating systems such as WINCE is not needed when the diagnostic apparatus starts, and therefore the system is quick to start; in scheduling the diagnostic program, the scheduling speed is fast and the instantaneity is high due to the single task execution.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a diagnostic program scheduling method and system, and a diagnostic instrument with the diagnostic program scheduling system. Background technique [0002] With the continuous development of automobile technology, more and more models are available, and the electronic structure of automobiles is becoming more and more complex, which makes the diagnosis and elimination of automobile faults more and more difficult. Therefore, a diagnostic instrument for diagnosing automobile faults has emerged as the times require. There are mainly two types of existing diagnostic instruments. One is the original instrument, which is not only expensive, but also has a single function. It can only diagnose specific vehicle models or faults, and cannot meet the needs. The other is a general-purpose diagnostic instrument, equipped with an operating system such as WINCE, capable of dispa...
