Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.

[0024] figure 1 A first embodiment of the invention is shown.

[0025] figure 1 It is a flow chart of a fault handling method for an embedded real-time operating system provided in the first embodiment of the present invention. This method is suitable for processing when the embedded real-time operating system encounters a serious fault, and can be executed by the embedded real-time operating system. The method specifically includes the following steps:

[0026] Step 110, start the embedded real-time operating system and en...

Abstract

The invention discloses a fault processing method and device for an embedded real-time operating system. The method includes: starting an embedded real-time operating system and entering a first application mode; detecting a first failure of the embedded real-time operating system in the first application mode; after detecting the first failure, If the embedded real-time operating system needs to be restarted, then determine the second application mode that the embedded real-time operating system enters after restarting, and execute the operating system restart; after restarting the embedded real-time operating system, enter the second application mode Two application modes. The invention avoids the repeated occurrence of system faults by restarting the operating system to dynamically switch the application mode.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of embedded systems, and in particular to a fault handling method and device for an embedded real-time operating system. Background technique [0002] Embedded real-time operating system is a kind of system that can accept and process at a fast enough speed when external events or data are generated, and the processed results can control the production process or respond quickly to the processing system within the specified time , and controls the embedded operating system where all real-time tasks run in unison. Embedded real-time operating systems are widely used in industrial control, military equipment, aerospace and other fields that have strict requirements on system response time. [0003] With the application of embedded real-time operating system more and more widely, the security of the operating system has been paid more and more attention. In the debugging process of the a...
