Smart Home Gateway Coordination Across Different Communication Standards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart household device control systems are limited by the ability of a single gateway to only facilitate interworking between devices using a single communication standard, restricting the application scenarios for smart devices with different communication standards.
Innovation Solution
A system comprising a primary gateway and a secondary gateway, each communicating using different standards, allowing the primary gateway to receive status information from both and generate control instructions for devices using different communication standards, enabling interworking control across multiple standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single gateway is used to control smart devices, then the device complexity is reduced, but the adaptability to different communication standards deteriorates
Solution Approach 1:
The system divides the gateway functionality into multiple independent gateways, each supporting a specific communication standard (e.g., Bluetooth gateway, ZigBee gateway, WiFi gateway). These segmented gateways work together under centralized coordination to provide multi-standard support without requiring each gateway to handle all standards, thus maintaining low individual complexity while achieving high overall adaptability.
Solution Approach 2:
The control server is designed with universal functionality to manage multiple types of gateways and smart devices through different communication standards. It provides standardized interfaces and protocols that enable it to interact with various gateways uniformly, achieving multi-functionality at the system level rather than requiring each gateway to be multi-functional.
2Adaptability or versatility
If multiple gateways supporting different communication standards are deployed, then the adaptability to different communication standards is improved, but the device complexity increases
Solution Approach 1:
The control server acts as an intermediary between multiple gateways and smart devices. It handles the complexity of multi-standard coordination, message routing, and protocol translation centrally, allowing individual gateways to remain simple and focused on their specific communication standards. This mediator approach distributes complexity appropriately and manages system complexity through centralized intelligence.
Solution Approach 2:
The system implements feedback mechanisms where the control server continuously monitors the status of multiple gateways and smart devices, dynamically adjusts message routing and coordination strategies, and manages resource allocation based on real-time system state. This feedback loop enables the system to adapt to changing conditions and maintain efficient operation despite the complexity of multiple gateways.
3Adaptability or versatility
If gateways are designed to support multiple communication standards, then the adaptability is improved, but the manufacturing precision and reliability of each standard implementation deteriorates
Solution Approach 1:
Each gateway is dedicated to a specific communication standard (e.g., Bluetooth, ZigBee, WiFi), allowing it to be optimized and thoroughly tested for that particular standard. This segmentation ensures high reliability and implementation quality for each standard while the system as a whole achieves broad adaptability through the collection of specialized gateways managed by the control server.
Data Source
AI summary
A system, method and gateway are provided. The method is executed by a primary gateway, and includes obtaining status information from smart devices, a first portion of which belong to and communicate with the primary gateway using a first standard, and a second portion of which belong to and communicate with a secondary gateway using a second standard. The status information from the smart devices belonging to the secondary gateway is received from the secondary gateway, and the status information from the smart devices belonging to the primary gateway is received directly from the smart devices belonging to the primary gateway. A control instruction for controlling a second smart device is generated in response to status information from a first smart device complying with an interworking rule, where the first and second smart devices communicate using different standards. The control instruction is transmitted to the second smart device.
