Smart Home Server Protocol Conversion via API Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT systems face challenges in enabling control commands between devices and user terminals operating on different protocols, limiting interoperability and versatility in smart home environments.
Innovation Solution
A smart home service server with an API controller, filter, and control command transmitter that converts control commands from one protocol to another, allowing authenticated user terminals to control devices across different protocols, and processes state information for transmission to user terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a smart home service server connects devices operated on a first protocol to user terminals operated on a second protocol, then interoperability between different protocols is improved, but device complexity increases due to protocol conversion requirements
Solution Approach 1:
The patent introduces a smart home service server as an intermediary component that receives control commands from user terminals via a second protocol, converts them to the first protocol, and transmits them to devices. This mediator architecture enables interoperability between different protocols without requiring direct protocol compatibility between terminals and devices, thus resolving the technical contradiction.
2Adaptability or versatility
If protocol conversion is implemented to enable control between different protocols, then versatility of IoT networks is improved, but system complexity increases due to conversion requirements
Solution Approach 1:
The smart home service server is designed with multi-functional capabilities including receiving control commands via multiple protocols, converting between different protocols, managing device connections, and handling state information. This universal server architecture consolidates protocol conversion functionality in a single system, enabling versatility across different IoT devices and terminals while managing system complexity centrally rather than distributing it across multiple components.

AI summary
A smart home service which is capable of providing an environment in which calling a control command for a device is available via a user terminal protocol to control between the device and a user terminal based on different type of protocol and a control method for the same. The smart home service server connecting at least one device operated based on a first protocol to at least one user terminal operated based on a second protocol, includes an application programming interface (API) controller configured to allow a control command for the at least one device to be called via the second protocol of the at least one user terminal; a filter configured to convert the called control command according to the first protocol; and a control command transmitter configured to transmit the control command converted according to the first protocol, to the at least one device.
