For achieving the above object, the present invention proposes the fault-tolerance processing method of a kind of files in embedded equipment system, it is characterized in that, may further comprise the steps:
The first step: in system's installation process, storage medium is divided into boot partition and work subregion; In boot partition, preserve software and configuration data, the system start-up Control Software etc. of necessity that the basic actuating section, computing machine of operating system can get in touch with the remote maintenance center;
Second step: in the system power-up start-up course, the operating system in the boot partition is given the Control Software of the system start-up in the boot partition with control;
The 3rd step: whether the file system in the start-up control software judgment task subregion is normal, and whether last system start-up is normal, if find system exception, changes for the 4th step; Otherwise changeed for the 5th step;
The 4th step: start-up control software is with can moving with software and the data graftabl that the remote maintenance center communicates of preserving in the boot partition, after the maintainer repairs the work subregion of system by the remote maintenance center, changeed for second step and restart operation;
The 5th step: will work software in the subregion and data of start-up control software are called in the system and are moved the system starting process normal termination.
Adopt the method for the invention by the storage medium in the embedded computer system being provided with independently a boot partition and an one or more work subregion, and under different condition, carry out different data processing.Compared with prior art, reached equipment has been carried out remote maintenance effect after the fault, saved maintainer and maintenance cost, reduced equipment failure repair time, improved equipment availability.
Description of drawings
Fig. 1 is that the pairing system of the present invention installs and the start-up course process flow diagram.
Embodiment
Below in conjunction with accompanying drawing is logical technical scheme of the present invention is described in further detail:
The present invention relates generally to a large amount of employing embedded computers, to reliability requirement very high the communications field in file system system handles method after the mistake appears.It is communication facilities (the following general designation embedded computer system that can carry out the embedded computer of remote maintenance management or adopt embedded computer system, the abbreviation system) the embedded type file management system that is adopted in occurs after the mistake, long-range method of carrying out system recovery.
As shown in Figure 1, the method for the invention is provided with independently a boot partition and an one or more work subregion with the storage medium in the embedded computer system.Each subregion adopts independently file system, and the mistake that the file system of a subregion occurs can not influence the file system of another subregion.In boot partition, preserve cover start-up control software and system and can normally start also and can get in touch necessary software and data with remote maintenance equipment.This a part of software and data can not rewritten in the whole life cycle of system, thereby can not cause file system to be destroyed; Software and data that system needs to change in operational process then are kept at the work subregion.After operating system started from boot partition, control was given start-up control software; Whether start-up control software is normal by the file system in certain algorithm judgment task subregion; If normal, will work software in the subregion and data of system are called in internal memory and are moved; If undesired, then the standby software preserved in the boot partition and data are called in the internal memory operation, by cooperate software in the subregion of will working and data to repair with the remote maintenance center after, change normal operation again over to.
Adopt a specific embodiment that the method for the invention is described in further detail below, suppose to adopt the main control veneer of base station system, veneer adopts CF (Compact Flash, standard flash memory) card has adopted VxWorks operating system, DOS file system to come management software and data as permanent storage media.
In this example, at first the CF card is divided 2 subregions, one of them is as boot partition, and another is as the work subregion.In the subregion registration form of system, the system that is provided with starts dos operating system from boot partition.Dos operating system has been installed in boot partition, will have been called in the system start-up Control Software after the dos operating system startup is finished.Because base station system is passed through at ATM (Asynchronous Transfer Mode, asynchronous transfer mode) (a kind of protocol name by ATM delivery network packet) mode of the IPOA on and remote operation maintaining center communicate, and base station system must be able to dispose the IPOA link data identical with remote system.In the present embodiment, just the software of system is kept in the boot partition with this a part of configuration data relevant with IPOA; Needed all data of normal operation have then been preserved in the work subregion.
