IoT Bridge Device Protocol Conversion for Smart Home Interoperability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of intelligentization reconstruction of home devices due to the need for changing communication protocols and modes to access the Internet of Things (IoT) limits the popularity of smart home applications, as different devices support various communication protocols such as infrared, Bluetooth, Wi-Fi, and power line carrier protocols.
Innovation Solution
A communication method and bridge device that receive data information carrying a specified identification, search for corresponding power consumption devices, determine if they support the same communication mode and protocol, and convert data information if different, allowing communication between devices with different protocols, thereby establishing connectivity without altering the original protocols of power consumption devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If home devices are reconstructed with sensing units, communication units, and execution units to access IoT, then IoT functionality is achieved, but the cost of intelligentization reconstruction increases significantly
Solution Approach 1:
The patent introduces a gateway device as an intermediary between existing home devices and the IoT network. The gateway performs protocol conversion and data translation, allowing devices with different communication protocols (infrared, Bluetooth, Wi-Fi, power line carrier) to access IoT without modifying the devices themselves. This mediator approach resolves the contradiction by maintaining device originality while enabling IoT connectivity.
Solution Approach 2:
The gateway device is designed with multi-functionality to support multiple communication protocols simultaneously. It can receive data from devices using various protocols, convert them to a unified format, and transmit to the IoT network. This universal capability allows diverse devices to access IoT without individual reconstruction, reducing overall system cost while maintaining adaptability.
2Adaptability or versatility
If different communication protocols are supported by home devices, then device compatibility is improved, but protocol conversion complexity increases
Solution Approach 1:
The gateway serves as a centralized intermediary that handles all protocol conversion operations. Instead of each device needing to support multiple protocols or perform complex conversions, the gateway consolidates this functionality. It receives various protocol types, converts them to a standard internal format, and manages communication with the IoT network, thereby reducing overall system complexity.
Solution Approach 2:
The patent merges multiple protocol handling capabilities into a single gateway device. Rather than distributing protocol conversion complexity across multiple devices, all protocol support functions are combined in the gateway. This consolidation simplifies the overall system architecture while maintaining compatibility with diverse communication protocols.

AI summary
An Internet of Things (IOT), a communication method, a bridge device and an access device for the IOT are disclosed. The method is applied to the bridge device for the IOT, and includes: receiving, by the bridge device, data information carrying a specified identification sent from an IOT access device; searching for, by the bridge device, a power consumption device in the IOT corresponding to the specified identification; determining, by the bridge device, whether the power consumption device and the IOT access device support the same communication mode and communication protocol; converting, by the bridge device, the data information into data information which is identifiable to the power consumption device, in the case that it is determined that the power consumption device and the IOT access device support different communication modes and communication protocols; and sending, by the bridge device, the converted data information to the power consumption device.
