Description

Air conditioner controller capable of being connected with multiple intelligent home platforms

Technical Field

The utility model relates to the technical field of intelligent home control, and particularly discloses an air conditioner controller capable of being connected with a plurality of intelligent home platforms.

Background

The current smart Home field belongs to a multi-platform coexistence stage, and currently mainstream smart Home/IOT (Internet of Things ) platforms at Home and abroad include, for example, "Apple HomeKit", "Google Home", "Alexa", and "millet family". And only intelligent home equipment under the same platform can directly realize mutual control or scene linkage, thereby realizing more intelligent application.

As an important control entrance of the smart home, a part of the smart home devices such as smart home devices under the Apple HomeKit platform can be controlled only by the mobile phones of the apples and other devices, and cannot be directly connected with the Android mobile phones for use.

The above situation brings a great deal of inconvenience and limitation to the consumer. After a consumer uses a product of one platform, the consumer is forced to deeply bind the intelligent home platform to construct the own intelligent home system, the cost of subsequently switching the intelligent home platform used by the consumer is very high (equivalent to the need of all re-purchase) and even the consumer cannot replace the intelligent home platform, and even if the consumer feels that the original platform is bad, the consumer can only be forced to continue to use due to the limited replacement cost.

At present, some technologies and schemes are available to try to solve the problem that the different intelligent home platform products cannot be interconnected and intercommunicated.

Such as: the cloud service platform is established, the intelligent home equipment is accessed to the self or public cloud service platform, and then the cloud service platform is simultaneously in cloud-cloud butt joint with each intelligent home platform, so that access of a plurality of platforms can be realized. However, the method requires a large amount of server resources, the system is complex, and the cost is high; moreover, many platforms limit the linkage capacity of the equipment accessed by the method, and other equipment in the home cannot be controlled or linked; a part of platforms such as Apple Homekit do not support the cloud docking mode, and only support the direct access of intelligent home equipment.

The universal intelligent home control protocol is established in the global scope, and the establishment of the promotion standard is truly in the industry at present, but the promotion and application are not widely performed at present.

In a commonly used Wi-Fi SOC (System on Chip) of the Internet of things, SDKs (Software Development Kit, software development kits) of a plurality of platforms are built at the same time, and the method is difficult to realize application of the platforms at the same time due to memory and operation performance limitation of the Wi-Fi SOC of the Internet of things.

The same function of the consumer can repeatedly install intelligent home settings of a plurality of platforms at the same time or replace equipment supporting the required platforms. The cost is increased by times, not only is the resource wasted, but also interfaces provided by some household equipment such as air conditioners and the like can not or are difficult to support a plurality of intelligent equipment to control simultaneously, and the feasibility is not realized.

Therefore, the above-mentioned defects of the existing smart home platform are technical problems to be solved in the present day.
