LPWA Device Management via Base Station Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Third generation household appliances often fail to connect to the IoT appliance control cloud due to lack of Wi-Fi access points at home and user difficulty in configuring Wi-Fi settings, resulting in limited network connection rates and reduced functionality.
Innovation Solution
The implementation of a device management system that utilizes LPWA technology to enable devices to connect to a cloud without requiring a Wi-Fi gateway, allowing them to transmit state information and maintain network connectivity even when powered off, using an LPWA communication module and a communications battery to ensure continuous communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Wi-Fi-based cloud connection is used for household appliances, then remote monitoring and control functionality is improved, but network connection rate deteriorates due to lack of Wi-Fi access points and user configuration difficulty
Solution Approach 1:
The patent introduces a base station as an intermediary device that bridges the appliance and the cloud server. The base station handles Wi-Fi connectivity and cloud communication, allowing appliances without Wi-Fi capability or in locations without Wi-Fi access points to connect to the cloud through the base station's network connection.
Solution Approach 2:
The patent divides the network connection function into separate components: the appliance connects to the base station via a first communication interface, and the base station connects to the cloud server via a second communication interface. This segmentation allows the appliance to remain simple while gaining cloud connectivity through the base station's network capabilities.
2Productivity
If device transmits state information continuously to server, then device management efficiency is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic transmission of state information from the appliance to the server through the base station, rather than continuous transmission. The appliance transmits state information at predetermined intervals, which maintains effective device management while significantly reducing power consumption compared to continuous communication.

AI summary
A device management system includes: a server (20) communicatively connected to a network; a base station (30) for long-distance wireless communication that is communicatively connected to the network; and a device (10) that is communicatively connected to the base station (30) and transmits, to the server (20) via the base station (30), state information indicating a state of the device (10). The server (20) receives the state information from the device (10), generates notification information in accordance with the received state information, and transmits the generated notification information to the device (10).
