Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling intelligent devices, such as lamps and air conditioners, are inconvenient and do not fully utilize their features due to the need for separate applications and wall control, limiting operational efficiency.
Innovation Solution
A method and device that uses a mobile terminal to scan for nearby intelligent devices via Bluetooth, prioritize those with strong signals, establish a connection, and send control instructions through an ad-hoc network, allowing unified control across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wall control is used to operate intelligent devices, then device control is achieved, but operational convenience is poor and device features cannot be fully utilized
Solution Approach 1:
The mobile terminal application serves as a universal control interface that can operate multiple types of intelligent devices (lights, air conditioners, curtains, etc.) through a single platform, replacing the need for device-specific controls and fully utilizing diverse device features through standardized yet adaptable control mechanisms
2Productivity
If separate applications are used for each intelligent device, then device control is achieved, but control efficiency is low and multiple applications are required
Solution Approach 1:
The patent merges control functionality for multiple intelligent devices into a single mobile terminal application. The system establishes one Bluetooth connection to a gateway device that then manages communication with multiple target devices, consolidating what would otherwise require multiple separate applications into a unified control interface, thereby improving control efficiency while managing device complexity
3Difficulty of detecting and measuring
If Bluetooth scanning is performed to discover intelligent devices, then device discovery is improved, but signal intensity verification is required to ensure reliable connection
Solution Approach 1:
The system performs Bluetooth scanning to discover intelligent devices and then measures the signal intensity of each discovered device. Based on this feedback, the system selectively establishes connections only with devices whose signal intensity exceeds a predetermined threshold, ensuring reliable communication while maintaining effective device discovery capability

AI summary
The present invention discloses a method and device for controlling an intelligent device, a computer device, and a storage medium. A major technical solution is as follows: acquiring, by a mobile terminal, broadcast messages of surrounding intelligent devices by means of Bluetooth scanning; displaying the broadcast messages of the intelligent devices with Bluetooth signal intensities exceeding a target numerical value on a screen interface of the mobile terminal; determining the intelligent device with the strongest Bluetooth signal displayed on the screen interface of the mobile terminal as a first intelligent device, and establishing a Bluetooth connection with the first intelligent device; and sending, by the mobile terminal, a device identification of a target intelligent device and a control instruction selected by a user from the intelligent devices displayed on the screen interface for controlling the target intelligent device to the first intelligent device when receiving the control instruction.
