Object-Model Linkage Control for Cross-Protocol Device Interconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In interconnection scenarios, devices often fail to link due to incompatible communication protocols, limiting the extension of linkage functions and requiring high development costs for new protocols, and resulting in poor universality across different functions.
Innovation Solution
A linkage system comprising an object model device, a non-object model device, and a main control device, where the main control device models functions to obtain object models with parameters, allowing it to drive these devices when target parameters change or are triggered, thereby enabling linkage without the need for specific protocols for each function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specific communication protocols are developed for each device function, then linkage reliability between devices is improved, but device complexity and development costs increase
Solution Approach 1:
The patent applies universality by creating a unified object model that can represent multiple device types and functions through a common interface. The main control device uses a single standardized object model framework to manage diverse devices (lights, curtains, AC units, etc.), eliminating the need for separate communication protocols for each device type while maintaining reliable control.
Solution Approach 2:
The object model serves as an intermediary layer between the main control device and various target devices. By translating device-specific operations into standardized object model commands (such as start(), stop(), adjust()), the system mediates communication between heterogeneous devices without requiring direct protocol integration for each device pair.
2Adaptability or versatility
If new communication protocols are developed to support more device linkage functions, then linkage functionality is improved, but development costs and time increase
Solution Approach 1:
The system achieves high adaptability through a universal object model that can accommodate various device types and linkage scenarios. The main control device can establish linkage between any combination of devices by creating appropriate object model instances, supporting functions like lighting control, curtain automation, temperature regulation, and entertainment systems without developing new protocols for each scenario.
Solution Approach 2:
The patent implements preliminary action by pre-defining a comprehensive object model framework that anticipates various device types and control operations. Device parameters, methods, and events are pre-structured in the object model, allowing rapid deployment of new linkage functions by simply instantiating existing object models rather than developing new communication protocols from scratch.
3Ease of operation
If a unified communication protocol is used across all devices, then ease of operation is improved, but linkage precision and control accuracy decrease
Solution Approach 1:
The system applies local quality by customizing object model parameters and methods for each specific device type while maintaining a unified overall framework. Each device (light, curtain, AC unit) has device-specific parameters (brightness, position, temperature) and control methods tailored to its requirements, allowing precise control without sacrificing the simplicity of the unified object model interface.
Solution Approach 2:
The object model enables precise control by allowing parameter changes at the device level while maintaining consistent operation syntax. Different device types can have different parameter sets (e.g., brightness for lights, position for curtains, temperature for AC), and the main control device can adjust these parameters with high precision through standardized object model methods, achieving both ease of operation and control accuracy.

AI summary
A linkage system includes an object model device, a non-object model device and a main control device; the object model device is configured to model a function of the object model device to obtain a first object model with a first parameter; the main control device is configured to model a function of the main control device to obtain a second object model, and model a function of the non-object model device to obtain a third object model; the second object model has a second parameter and the third object model has a third parameter; the main control device is further configured to drive at least one of the object model device, the non-object model device and the main control device in response to determining that a target parameter is changed or triggered.
