Abstract: :Based on the current situation that smart home products between different manufacturers and different brands cannot achieve the true interoperability, an implementation of an intelligent gateway is proposed, including hardware and software solutions. In terms of hardware, the intelligent gateway can not only connect a variety of home products which have different interface types, but also can provide interfaces for connecting different cloud platforms. In terms of software, the registration of products in the cloud is realized, the collection and reporting of product data is realized, and finally, the products can be remotely controlled. In addition, mutual control between different products is also realized. Otherwise, this multi-protocol intelligent gateway has some advantages, such asflexible, practical and low cost.

Key words: Intelligent gateways, Multi-protocol conversion, Interconnection, Smart home appliance
