Solution Overview

Problem

The control of multiple smart devices in different areas often results in user errors due to confusion, as users may inadvertently select the wrong device, leading to incorrect commands.

Innovation Solution

A method and apparatus that identify a target relay node within a group network, determine its scene label, and send control instructions to proxy nodes in the correct area by comparing labels with a database, ensuring accurate command execution without user selection from multiple devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users control multiple smart devices through one application software, then all smart devices can be controlled in a unified manner, but control errors occur due to user confusion when selecting devices in different areas

Engineering Contradiction:
ImproveUnified control of smart devicesVSAvoidControl accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a relay node as an intermediary between the terminal and proxy nodes. The relay node receives control instructions from the terminal, identifies the target area through scene labels, and forwards instructions to the appropriate proxy node. This mediator mechanism eliminates the need for users to directly select devices across different areas, preventing control errors while maintaining unified control through the application software.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the smart device control system into distinct functional components: terminal, relay node, and proxy nodes. Each component has a specific role - the terminal initiates control, the relay node routes instructions based on scene labels, and proxy nodes execute commands. This segmentation allows unified control interface while ensuring accurate device selection through automated routing.

Inventive Principle:
Principle #1Segmentation

2Reliability

If scene label verification is performed by comparing identified labels with pre-configured labels in a database, then control accuracy is improved by preventing errors, but additional verification steps increase system complexity

Engineering Contradiction:
ImproveControl accuracyVSAvoidSystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by pre-configuring scene labels in a database before actual control operations. When a relay node receives a control instruction, it compares the identified scene label against the pre-stored label to verify correctness. This advance preparation ensures accurate device selection without requiring complex real-time decision-making, maintaining reliability while managing system complexity through structured data storage.

Inventive Principle:
Principle #10Preliminary action

AI summary

The present application provides a smart device control method, a smart device control apparatus, an electronic device, and a computer readable medium. The method includes: determining a target relay node connected to a current terminal after the current terminal enters a target group network; identifying a scene label carried by the target relay node, the scene label being a label of a target area where the target relay node is located, each area including one relay node and at least one proxy node, and each node corresponding to one smart device; and sending a control instruction to the target relay node in a case that it is determined that scene label is labeled correctly, and transmitting, by the relay node, the control instruction to the proxy node in the target area.
