The method for imparting video capability to IoT devices needs to be implemented by relying on a general-purpose video device access platform (already filed) based on the internet of things operating system provided in the following embodiment 1, and therefore, the architecture and principles of the general-purpose video device access platform based on the internet of things operating system are described herein first.
The invention realizes a universal monitoring video history video downloading method based on the hardware of a universal video device access platform and the software endowing the internet of things operation system with video capability to the internet of things (IoT) device, and the method not only can download different streaming protocols, but also does not occupy the foreground page of a browser and provides the capability of history downloading records.
The downloading case of the universal monitoring video history video downloading method of the present solution will be further described below with reference to the universal video device access platform.
Example 1
As shown in fig. 1, in one aspect, the present application proposes a universal video device access platform based on an operating system of the internet of things, including:

and the service application is respectively in integrated communication connection with the video configuration and the equipment.
In the scene of the internet of things, the access of video equipment always has an access scheme which cannot be flexible and unified: or, the video devices are accessed one by one in a driving mode according to the access mode of the Iot device, and the self-registration of the devices cannot be achieved in the mode; or the video equipment is accessed as a platform alone, and the purpose of unified management of the video equipment and the Iot equipment cannot be achieved in the mode.
For the up-service, the device integration is the portal for all internet of things devices (IoT devices), and all devices (including video devices) are queried through the device integration, so that unification can be achieved. And the video configuration is directly inquired, so that the unification is not realized, and the value of the operation system of the Internet of things is weakened.
Therefore, the interfaces of the IoT devices (including the device ids) are synchronized to the "device integration", instead of directly reporting the "IoT device ids" to the service application directly through the "video configuration" (mainly because of the protocol mismatch), which is equivalent to the device integration providing the interface conversion function to realize the unified query and management of all the internet of things devices.
