Bluetooth LAN Control via UDP Gateway Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing local area network (LAN) control systems are inconvenient and inefficient due to the need to use multiple applications or remote controls for managing various devices, and centralized control solutions require cloud services, increasing costs.
Innovation Solution
A local area network control system based on Bluetooth and user datagram protocol (UDP) that includes multiple Bluetooth devices, gateways, and a control device, where gateways exchange information via UDP to enable centralized control of all devices through any gateway without the need for cloud services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If centralized control solutions are implemented, then control convenience and efficiency are improved, but system cost increases due to cloud service requirements
Solution Approach 1:
The patent extracts the control functionality from cloud-based centralized systems and implements it locally using Bluetooth Low Energy (BLE) technology. The control device directly communicates with Bluetooth devices through BLE protocols, eliminating the need for cloud services and reducing system cost while maintaining centralized control convenience.
Solution Approach 2:
The patent introduces a Bluetooth Low Energy (BLE) intermediary layer between the control device and Bluetooth devices. This BLE intermediary enables direct local communication, replacing the cloud service mediator and achieving cost-effective centralized control through the message queue mechanism and device management protocols.
2Adaptability or versatility
If multiple applications or remote controls are used to manage various devices, then device compatibility is improved, but operational complexity increases
Solution Approach 1:
The patent creates a universal control device capable of managing multiple types of Bluetooth devices through a single interface. The control device uses Bluetooth Low Energy (BLE) protocols to communicate with various Bluetooth devices (lights, locks, sensors, etc.), providing multi-functional control without requiring separate applications for each device type.
Solution Approach 2:
The patent merges multiple device control functions into a single control device interface. By combining the control capabilities for lights, locks, sensors, and other Bluetooth devices into one unified application, the system reduces operational complexity while maintaining broad device compatibility through the BLE message queue mechanism.

AI summary
A local area network control system based on Bluetooth and user datagram protocol (UDP), which includes a plurality of first Bluetooth devices, a first gateway, a plurality of second Bluetooth devices, a second gateway, and a control device. The first gateway manages the first Bluetooth devices. The second gateway manages the second Bluetooth devices. The first gateway broadcasts an information exchange request message based on UDP. The second gateway receives and analyzes the information exchange request message to obtain the gateway information of the first gateway, and return an information message based on UDP to the first gateway. The first gateway receives and analyzes the information message to obtain the gateway information of the second gateway. The control device controls one or more of the first Bluetooth devices and the second Bluetooth devices via either the first gateway or the second gateway.
