Method and related device for online upgrading software of credible DCS (Distributed Control System) upper computer

Abstract

The invention provides a method and a related device for online upgrading software of a trusted DCS (Distributed Control System) upper computer. The method comprises the following steps: S1, obtaining a new version software package; s2, decompressing the new version software package to obtain an ELF file; s3, detecting whether the ELF file meets the dependency during operation or not, and if the ELF file does not meet the dependency during operation, returning to S1; and if the dependency during operation is met, upgrading the current old software in the credible DCS upper computer into the new version software in the new version software package. Before the software is upgraded, whether the ELF file of the new-version software meets the operation dependency or not is checked firstly, if not, the new-version software is not installed, and if yes, the new-version software is installed; the reason is that if the software depends on fracture, the software cannot run even if the new version of software is successfully installed, and upgrading fails.

Description

Technical Field

[0001] The invention belongs to the field of distributed control systems and relates to a method for online upgrading software of a trusted DCS host computer and a related device. Background Art

[0002] Distributed Control System (DCS) is the core equipment of power system infrastructure. Distributed Control System includes trusted DCS host computer and trusted DCS controller. Trusted DCS host computer includes terminals such as engineer station and operator station. Trusted DCS host computer and trusted DCS controller are registered in the trusted management center, and these terminals are managed uniformly by the trusted management center. With the increase of business scenarios, the probability of vulnerabilities (BUGs) in the software running on the trusted DCS host computer is increasing. At the same time, the software is also being continuously iterated and optimized, so it is necessary to upgrade the software on the trusted DCS host computer.

[0003] At present, the software upgrade of the trusted DCS host computer is generally done manually, which is to upload the new version of the software to the trusted DCS host computer that needs the software upgrade, manually install the old version of the software, and then start the new version of the software. This upgrade method has high technical requirements for personnel, consumes manpower, has a long cycle, is prone to errors, and reduces customer satisfaction. Summary of the invention

[0004] In order to solve the above problems of the prior art, the present invention provides a method and related device for online software upgrade of a trusted DCS host computer, so as to solve the problems that the prior software upgrade is time-consuming and labor-intensive and has low customer satisfaction.

[0005] The present invention is achieved through the following technical solutions:

[0006] A method for online software upgrade of a trusted DCS host computer, comprising:

[0007] S1, obtain the new version of the software package;

[0008] S2, decompress the new version software package to obtain an ELF file;

[0009] S3, detecting whether the ELF file satisfies the runtime dependency, if not, returning to S1; if the runtime dependency is satisfied, upgrading the current old software in the trusted DCS host computer to the new version of the software in the new version of the software package.

[0010] Preferably, S1 specifically includes:

[0011] S11, receiving an upgrade information file issued by a trusted management center, wherein the upgrade information file includes a version number of a new version of the software;

[0012] S12, compare the version number of the current old software in the trusted DCS host computer with the version number of the new software to determine whether the new software meets the upgrade conditions. If not, return to S11; if the upgrade conditions are met, download the new software package corresponding to the new software from the trusted management center, and send the download progress back to the trusted management center in real time to proceed to S2.

[0013] Preferably, S2 specifically comprises: decompressing the new version software package to obtain an ELF file and a dynamic library of the new version software.

[0014] Furthermore, in S3, the detecting whether the ELF file satisfies the runtime dependency is specifically: detecting whether the ELF file satisfies the runtime dependency, and whether the dynamic library of the new version of the software satisfies the runtime dependency.

[0015] Preferably, S2 specifically comprises: decompressing the new version software package to a temporary folder to obtain an ELF file.

[0016] Further, in S3, if the runtime dependency is not satisfied, then return to S1, specifically: if the runtime dependency is not satisfied, then clean up the temporary folder and return to S1.

[0017] Furthermore, in S3, if the runtime dependency is met, the current old software in the trusted DCS host computer is upgraded to the new version of the software in the new version of the software package, specifically: if the runtime dependency is met, the service of the current old software in the trusted DCS host computer is stopped, and the old software is backed up; the old software is replaced with the new version of the software in the new version of the software package; the new version of the software is started to detect whether the new version of the software runs normally; if it does not run normally, the old software is restored, and if it runs normally, the temporary folder is deleted.

[0018] A system for online software upgrade of a trusted DCS host computer, comprising:

[0019] Get module, used to get the new version of the software package;

[0020] A decompression module is used to decompress the new version software package to obtain an ELF file;

[0021] The upgrade module is used to detect whether the ELF file meets the runtime dependency. If it does not meet the runtime dependency, the software upgrade is not performed; if it meets the runtime dependency, the current old software in the trusted DCS host computer is upgraded to the new version of the software in the new version of the software package.

[0022] A computer device comprises a memory, a processor and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the steps of the above-mentioned method for online software upgrade of a trusted DCS host computer are implemented.

[0023] A computer-readable storage medium stores a computer program, which, when executed by a processor, implements the steps of the above-mentioned method for online software upgrade of a trusted DCS host computer.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] Before upgrading the software, the present invention first checks whether the ELF file (executable and linking format) of the new version of the software meets the running dependency. If it does not meet the running dependency, the new version of the software will not be installed, and the new version of the software will be installed only if it meets the running dependency. The reason is that if the dependency is broken, even if the new version of the software is successfully installed, it cannot be run, resulting in the failure of the upgrade. Through the method of the present invention, the software can be automatically upgraded, effectively reducing the technical requirements for manpower, saving time and effort, and improving customer satisfaction.
