Method and device improving operation system reliability

Abstract

The invention relates to a method and device improving operation system reliability. The method includes receiving a BIOS start guidance instruction; reading a main guidance section, and loading a corresponded operation system guidance program according to the main guidance section; loading an operation system kernel; loading a file system, and loading a preset application program component according to the file system; storing the operation system guidance program, the operation system kernel, the file system and the application program component in a first storage region, which is a read-only one, in an image manner; storing data in a second storage region, which is a read and write one, during the operation of the application program component and operation system kernel. The data include at least one of the generated files, logs and database records. By the aid of the method, the reliability of the operation system can be improved.

Description

technical field [0001] The invention relates to the technical field of operating systems, in particular to a method and device for improving the reliability of an operating system. Background technique [0002] Special computers often work in harsh environments such as high temperature, low temperature, humidity, vibration, illegal switching, irregular operation, electromagnetic interference and voltage instability, which seriously affect the reliability of special computers. Special computers require high reliability, otherwise it will cause property damage or even casualties, such as subways, high-speed rail, CNC machine tools, medical equipment, and power substations. If there is equipment failure, the consequences are often very serious. The operating system reliability of a special computer is an important indicator of a special computer. [0003] However, the inventor has found through research that at least the following problems exist in the process of operating sys...

Problems solved by technology

[0003] However, the inventor has found through research that at least the following problems exist in the process of operating system startup, loading, operation and exception handling in the prior art. Taking the embedded linux operating system as an example, the linux used in the traditional technology is all in the release version Linux system (such as fedora, ubuntu, cenos, debian, suse, etc.) based on which some components have been deleted (or a simplified version of the linux system), and because the embedded linux system is very large and complex, this method It often causes system customizers to be unable to grasp the dependence of system components and the reliability of the components themselves, resulting in various probabilistic anomalies in customized systems

Moreover, the traditional method of starting, loading and running the operating system can easily cause the operating system to fail to start, and there is no mechanism to restore the system when it fails to start

Therefore, the reliability of the operating system in the traditional technology is not high
