Interfacing Device Control for Multi-Vendor Sensor Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current home automation systems lack interoperability between different devices and vendors, leading to limited customization and increased costs due to proprietary communication protocols, making it difficult to integrate devices from various manufacturers into a unified smart home solution.
Innovation Solution
A centralized controller system that uses interfacing devices with IP-based networks to monitor and control various physical devices from different vendors, allowing for unified management and configuration via a graphic user interface, enabling the creation of compound rules for automated operations across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary communication protocols are used for device integration, then device compatibility within the same vendor is improved, but system interoperability between different vendors deteriorates
Solution Approach 1:
The patent introduces a gateway device as an intermediary between sensor devices with proprietary protocols and the central control system. The gateway translates proprietary protocols into standard IP-based communications, enabling interoperability between different vendor devices while maintaining reliable communication within each vendor's device group.
Solution Approach 2:
The control system is designed to support multiple communication protocols simultaneously through the gateway architecture. The system can handle both proprietary protocols from different vendors and standard IP-based protocols, making the system universally compatible with diverse sensor devices from various manufacturers.
2Ease of operation
If dedicated control devices from the same vendor are used, then centralized control capability is improved, but system customization and vendor flexibility deteriorate
Solution Approach 1:
The gateway acts as a mediator that enables centralized control of heterogeneous devices from different vendors. It translates various proprietary protocols into a unified communication standard that the central control system can manage, providing centralized control capability while accepting devices from multiple vendors.
Solution Approach 2:
The system architecture segments the control function into two parts: the gateway handles protocol translation and local device communication, while the central control system handles unified management. This segmentation allows the central system to maintain simplified control capabilities while the gateway manages the complexity of multi-vendor protocol compatibility.
3Adaptability or versatility
If existing sensors and appliances from various vendors are integrated, then system customization is improved, but integration complexity and cost increase
Solution Approach 1:
The gateway serves as an intermediary that simplifies integration by handling all protocol translation complexities. Existing sensors and appliances from various vendors can be integrated without increasing overall system complexity because the gateway absorbs the integration complexity through its translation capabilities.
Solution Approach 2:
The gateway is designed to automatically discover and adapt to different sensor device protocols through self-configuration. This self-service capability reduces integration complexity by eliminating the need for manual protocol configuration and simplifies the integration process for customizing systems with devices from various vendors.

AI summary
A device controlling system configures, monitors, and controls one or more interfacing devices, such that an interfacing device can obtain and disseminate sensor data from one or more attached physical devices that include sensors for measuring physical attributes. During operation, the system can configure an interfacing device by establishing a network connection with an interfacing device, and determining one or more rules for the interfacing device. A rule can indicate an action description for performing an action, and indicates a condition that indicates criteria for processing the rule's action description. The system can configure the interfacing device to process its associated rules.
