Secure computer platform supporting software batch remote updating

Abstract

The invention relates to a safe computer platform supporting software batch remote updating. The platform is connected with an upper computer maintenance tool, the safety computer platform comprises acommunication unit and an execution unit, the upper computer maintenance tool is connected with the communication unit, the communication unit controls a controlled object through the execution unit,and the safety computer platform further comprises a communication forwarding part and an online updating part. The communication forwarding part is arranged in a communication unit of the security computer platform and is used for interacting information with an upper computer maintenance tool and forwarding the information to a corresponding target machine; the online updating part is arrangedin each target machine and used for batch parallel remote updating of the multiple target machines, and it is guaranteed that the updating process is safe and reliable. Compared with the prior art, the method has the advantages that the target machines can be remotely updated in parallel in batches, the updating process is safe and reliable, and reuploading and version rollback are supported.

Description

technical field [0001] The invention relates to the field of railway signaling systems, in particular to a secure computer platform supporting software batch remote update. Background technique [0002] The safety computer platform is a fault-oriented and safe underlying platform with good versatility. On the basis of not changing the hardware and core software, different application systems can be built only through application software development and hardware configuration. It is a railway signal system core component of the . [0003] After the railway signaling system is put into use, it is inevitable to encounter function expansion and software defects, and software updates are required. Currently the most commonly used method is manual programming block by block. This method needs to stop the system operation, disassemble the target machine piece by piece, the update speed is slow, and the manual operation is complex and cumbersome, which easily leads to omissions o...

AI Technical Summary

Problems solved by technology

This method needs to stop the system operation, disassemble the target machine piece by piece, the update speed is slow, and the manual operation is complicated and cumbersome, which may easily lead to omissions or mistakes

At the same time, the following characteristics of the railway signal system lead to very high cost and difficulty of manual upgrade

(1) The work time is tight and there are many restrictions

(2) There are many operating equipment and different operations

(3) Operating equipment is widely distributed, and some are in harsh environments such as ultra-low temperature and high altitude

(5) Some devices are highly enclosed, leaving only internal communication and power interfaces, which cannot be updated separately

[0005] (1) Lack of a perfect protection mechanism, network interruption, wrong upgrade, etc. will easily lead to system paralysis

[0006] (2) It is only for a single board update, and there are few studies on mass update

[0007] (3) There are few studies on remote updating of closed devices without network interfaces

[0008] (4) The security and versatility of the security platform are not utilized, and multiple systems develop the remote update function independently
