IoT Server Region Noise Control via User Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In IoT environments, noise generated in one region of a multi-regional building can disturb users in adjacent regions, such as floor noise from impact or device operations, leading to discomfort and potential social issues.
Innovation Solution
A method and apparatus where a server acquires situation information from one region, determines the user's state, and adjusts device settings in adjacent regions to minimize noise disturbance by transmitting device set-up values, such as maximum volume levels or operation levels, based on the user's presence or absence, using sensors like motion detection and door open/close sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user in one region operates devices that generate noise (TV, cleaner, etc.), then the user's convenience and operational efficiency are improved, but noise is transferred to neighboring regions causing disturbance and discomfort to users in adjacent regions
Solution Approach 1:
The system performs preliminary detection of user presence in neighboring regions before allowing device operation. Motion sensors and door sensors detect whether neighbors are present in advance, and the server pre-adjusts device settings (volume limits, operation restrictions) based on this detected state, preventing noise disturbance before it occurs
Solution Approach 2:
The system establishes a feedback loop where sensors continuously monitor user presence in both the current region and neighboring regions. This real-time feedback information is transmitted to the server, which dynamically adjusts device operation parameters and provides feedback notifications to users, creating a closed-loop control system that balances operational convenience with noise control
2Object-affected harmful factors
If the server controls device settings in adjacent regions based on user presence detection, then noise disturbance between regions is reduced, but system complexity and the number of components increase
Solution Approach 1:
The server performs multiple functions within a single centralized platform: it receives and processes sensor data from multiple regions, determines user presence states, controls device settings across different regions, and sends notifications to users. This multi-functional approach consolidates what could be multiple separate systems into one universal platform, reducing overall system complexity
Solution Approach 2:
The server acts as an intermediary between the physical environment (sensors, devices, users) and the control logic. It mediates the interaction by receiving raw sensor data, processing it to determine user presence, translating this into appropriate device control commands, and coordinating communications between neighboring regions. This intermediary role simplifies the system architecture by centralizing the complex decision-making process
3Measurement precision
If motion sensors and door sensors are installed to detect user presence, then accurate detection of neighboring users is achieved, but manufacturing cost and device complexity increase
Solution Approach 1:
The installed sensors serve multiple purposes: motion sensors detect both the user in the current region and users in neighboring regions, door sensors monitor both local and adjacent door states. This multi-functional use of sensors maximizes their value and reduces the need for additional dedicated sensors, thereby controlling manufacturing costs while maintaining high detection accuracy
