Description
Technical field
The present invention relates to internet of things field more particularly to a kind of Internet of Things operating system online upgrading methods.
Background technique
At present the operating system update method of mainstream substantially there are two types of: one is in desktop system commonly with single independent
Software package is the upgrade method of basic unit, for can be with unrestricted choice some to be updated independent software packages.Desktop system
Using single independent software package as basic unit method for upgrading system upgrade flexibility ratio it is higher, user can be according to actual needs
The software package that selection needs is upgraded, and without checking for unwanted upgrading software package, reduces the operating system of user
Use cost.But if user installs a certain independent software package to conflict with operating system version by force, operation may result in
The dependence of the software of all installations and operating system itself ruptures in system, or will affect the stability of operating system, very
To may cause system crash.
Another existing upgrade method is whole upgrade method, and in the method, software is divided into application by operating system
Software and system component, application software supports user's standalone upgrade, but system component must be using the method integrally upgraded.Due to
This method needs the system component installation kit of disposable downloading large capacity, and may deposit in the system component installation kit downloaded
The system component of upgrading is not needed in the operating system, not only wastes the memory space of operating system, but also extend system
Update time.If above two method for upgrading system is applied to Internet of Things operating system, Internet of Things net operation system will affect
The operation stability and system upgrade of system are born.
Summary of the invention
In view of above-mentioned technical problem, the purpose of the present invention is to provide a kind of Internet of Things operating system online upgradings
Method, to solve the above technical problems.
The present invention solves its technical problem and adopts the technical scheme that, provides a kind of Internet of Things operating system online upgrading side
Method realizes, the online upgrade system includes: by an online upgrade system
