Home Automation Gateway Protocol Translation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Home automation installations face challenges in easy communication and control due to the presence of different communication protocols, leading to increased costs and complexity, and limited accessibility for remote devices to interact with local area network devices.
Innovation Solution
A configuration method that allows home automation devices to communicate with a central control unit using a first protocol, enabling conversion rules to translate device functions and state variables into a target communication protocol, enabling integration with a wide area network without modifying existing devices or control units, and allowing virtualization of devices for remote monitoring and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple local communication protocols are implemented to communicate with different home automation devices, then communication compatibility is improved, but device complexity and programming cost increase
Solution Approach 1:
The patent introduces a gateway device as an intermediary between home automation devices using local protocols and the IP-based network. The gateway translates messages from multiple local protocols (Z-Wave, Zigbee, Bluetooth, etc.) into a unified IP-based communication format, eliminating the need for the central control unit to implement multiple protocol stacks directly.
Solution Approach 2:
The gateway device is designed to support multiple communication protocols simultaneously, providing universal communication capability. It can receive messages from devices using different local protocols and forward them appropriately, making the central control unit protocol-agnostic and reducing its complexity.
2Ease of operation
If home automation devices are disposed on a local area network, then local communication is enabled, but remote accessibility is limited
Solution Approach 1:
The patent extends the communication from a two-dimensional local area network to a three-dimensional network space by introducing IP-based wide area network connectivity. The gateway establishes TCP/IP connections that allow remote devices to access the local home automation network through the internet or other wide area networks, adding a remote access dimension to the originally local system.
3Adaptability or versatility
If proprietary local protocols are used for home automation devices, then device-specific communication requirements are met, but integration cost and complexity increase
Solution Approach 1:
The gateway serves as a cost-effective intermediary that handles protocol-specific functionality. Instead of requiring the central control unit to support multiple proprietary protocols directly (which would increase its cost and complexity), the gateway absorbs the protocol-specific implementation costs and provides a standardized IP-based interface to the central control unit.
