Abstract

The invention discloses a system and method for real-time equipment driving restoration, and relates to the field of operating systems. The system comprises a control module, a backup driving module and a simulation equipment module, wherein the control module is connected with a normal driver and the backup driving module, and is used for managing the normal driver, the backup driving module andthe simulation equipment module; the backup driving module is used for backing up the motions of the normal driver; and the simulation equipment module is connected with the backup driving module, and is used for simulating hardware equipment connected with the normal driver. According to the system and method, through the cooperation of the control module, the backup driving module and the simulation equipment module, the driving can be replaced and restored in time when the normal drivers fails, thus the reliability of real-time equipment driving is improved and the integral reliability of real-time equipment is further improved.

Description

technical field [0001] The invention relates to the technical field of operating systems, in particular to a real-time device driver recovery system and method. Background technique [0002] Reliability is an important goal of an operating system. 85% of Windows XP operating system failures are caused by device drivers. The failure frequency of Linux operating system device drivers is more than 3-7 times that of other parts. Real-time devices are widely used in aerospace, medical and other fields. A failure of a real-time device driver may cause inestimable losses. Therefore, it is of great significance to improve the reliability of a real-time device driver. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is: how to provide a real-time device driver recovery system and method, so as to improve the reliability of the real-time device driver, and further improve the overall relia...
