Problems solved by technology

[0005] Although there are many researches on the remote upgrade of the operating system in the existing technology, there are few researches on the remote upgrade of the operating system of the distribution automation terminal. In addition, the existing local upgrade solution is to bundle the Linux kernel and the root file system together to upgrade simultaneously. , the upgrade method is not flexible enough

Embodiment 1

[0074] An embodiment of the present invention provides a method for upgrading the operating system of a power distribution automation terminal based on a cloud master station, including:

[0075] (1) Receive the remote upgrade distribution automation terminal operating system command initiated by the cloud master station through the MQTT communication service;

[0076] (2) Download the operating system upgrade package from the cloud master station based on the HTTPS file service;

[0077] (3) Set the Boot upgrade flag / backup user application software operating parameters and restart;

[0078] (4) After entering the RecoveryOS system, upgrade the Linux operating system, restore the operating parameters of the application software, and restart after the upgrade is completed;

[0079] (5) Enter the normal operation of the operating system, and send the upgrade result to the cloud master station at the same time.

[0080] In a specific implementation manner of the embodiment of ...

Embodiment 2

[0103] An embodiment of the present invention provides a method for upgrading the distribution automation terminal operating system based on the cloud master station, such as figure 1 shown, including:

[0104] S1, pack the Linux kernel / root file system used for upgrading together and carry out digital signature to form a system upgrade package;

[0105] S2. The cloud master station initiates a command to remotely upgrade the operating system of the power distribution automation terminal through the MQTT communication service;

[0106] S3. The terminal downloads the operating system upgrade package from the cloud master station through the HTTPS file service;

[0107] S4, the terminal sets the Boot upgrade flag / backup user application software operating parameters, and restarts the terminal;

[0108] S5. After the terminal enters the RecoveryOS system, the Linux operating system is upgraded and the operating parameters of the application software are restored, and the termin...

Abstract

The invention discloses a method, a device and a system for upgrading a power distribution automation terminal operating system based on a cloud master station. The method comprises the following steps: receiving a command for remotely upgrading the power distribution automation terminal operating system initiated by the cloud master station through MQTT communication service; downloading an operating system upgrade package from the cloud master station based on HTTPS file service; setting a Boot upgrade flag bit / backing up user application software operation parameters and restarting; after entering the Recovery OS system, upgrading the Linux operating system, recovering running parameters of the application software, and restarting after upgrading is completed; and entering a normal operating system to run, and meanwhile, sending an upgrading result to the cloud master station. According to the invention, the upgraded terminal can be immediately put into normal work, and the upgrade result is notified to the cloud master station.

Description

technical field [0001] The invention belongs to the technical field of operating system upgrades, and in particular relates to a method, device and system for upgrading a distribution automation terminal operating system based on a cloud master station. Background technique [0002] Distribution automation terminals generally need to run in unattended environments such as feeder terminals on poles / ring network cabinets / switching stations. When the operating system has system software service problems or needs new functions, it involves operating system Upgrade operation. [0003] For the distribution automation terminal using the embedded Linux operating system, due to the characteristics of the Linux operating system, after the root file system of the distribution automation terminal is started, the root file system cannot be directly upgraded online. [0004] When the operating system of the existing distribution automation terminal is upgraded, the maintenance engineer o...
