USB interface-based unmanned ship system automatic upgrading method

Abstract

The invention provides a USB interface-based unmanned ship system automatic upgrading method. The method comprises the following steps: a key distribution step of distributing a private key and a public key in an unmanned ship system and a mobile storage device respectively; an upgrading file search step of automatically detecting a system upgrading package in the mobile storage device by a to-be-upgraded system in an unmanned ship and decrypting the system upgrading package through the private key; a system version comparison step of comparing a version number of the to-be-upgraded system with a version number of the system upgrading package after successful decryption and performing upgrading file copying operation if a version in the system upgrading package is relatively new; and an upgrading script step of automatically executing related upgrading scripts by the system after successful upgrading file copying. The system upgrading process is relatively simple; during system upgrading, the unmanned ship system is automatically upgraded; the unpredictable situation of information leakage, system false upgrading or the like does not occur; and the system upgrading time is greatlyshortened.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method for automatically upgrading an unmanned ship system based on a USB interface. Background technique [0002] At present, the update of the unmanned ship system is manually updated. The update of the host computer software is to copy the files to be updated to the target machine through a mobile storage device, such as a U disk, or directly reinstall the control software. [0003] When upgrading the ship control system, it is necessary to connect the serial port or network port to the development board, then manually copy the upgrade file to the development board, and then upgrade the ship control through a series of manual commands. For maintenance personnel, manually updating the system maintenance is time-consuming and laborious. [0004] The disadvantages of the above-mentioned upgrade method are as follows: [0005] 1. Time-consuming and labor-intensive, m...

AI Technical Summary

Problems solved by technology

[0005] 1. Time-consuming and labor-intensive, maintenance personnel need to check the files carefully;

[0006] 2. There is a risk of information leakage. Since the upgrade file is not encrypted, too many details are exposed during the upgrade process;

[0007] 3. There is a high possibility of misoperation, because different ships may correspond to different unmanned ship systems, and maintenance personnel are likely to upgrade different unmanned ship systems;

[0008] 4. The integrity of the upgrade file cannot be guaranteed;

[0009] 5. There is no system repair function, and only all updates can be performed after a certain part of the system has a problem
