BLE/WiFi Bridge Audio Sensor Hazard Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing alarm systems in dwellings are often costly to update, lack interoperability between different manufacturers, and require separate devices for smoke detection and other hazard detection, making them inefficient for comprehensive monitoring and communication with the internet.
Innovation Solution
A Bluetooth/WiFi bridge system that integrates a computing device with internet-facing radios and audio sensors, enabling communication between non-internet-connected devices and the internet, allowing for the analysis of alarm sounds and status updates from devices like door locks, smoke detectors, and intrusion sensors, and facilitating the detection of potential hazards like fires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing alarm systems are used, then safety monitoring is provided, but system cost and complexity increase when updating or extending functionality
Solution Approach 1:
The alarm panel is designed to accept multiple types of sensors (smoke, heat, carbon monoxide, motion, door/window contacts) and communication methods (hardwired, wireless RF, cellular) through a single integrated unit. This allows the system to perform multiple safety monitoring functions without requiring separate dedicated devices for each sensor type or communication method, thereby reducing overall system complexity while maintaining comprehensive safety monitoring.
Solution Approach 2:
A communication interface module serves as an intermediary between various sensors and the central alarm panel. This module handles signal conditioning, protocol conversion, and data formatting, allowing different sensor types to communicate through a standardized interface. This intermediary layer simplifies system integration and reduces complexity when adding or updating sensor functionality.
2Adaptability or versatility
If traditional alarm systems are used, then basic alarm functionality is provided, but interoperability between different manufacturers' devices is limited
Solution Approach 1:
The alarm panel incorporates multiple communication protocols (RF, cellular, Ethernet, Wi-Fi) and universal sensor interfaces that can accommodate devices from different manufacturers. The system can accept signals from various sensor types and transmit alerts through multiple communication channels, enabling interoperability without requiring manufacturer-specific proprietary systems.
Solution Approach 2:
The communication interface module can dynamically adjust communication parameters such as frequency, protocol type, and data format to match different sensor and transmission devices. This adaptability allows the system to interface with diverse manufacturers' equipment by changing communication parameters rather than requiring fixed proprietary connections.
3Adaptability or versatility
If separate devices are used for different hazard detection, then comprehensive monitoring is achieved, but device quantity and installation complexity increase
Solution Approach 1:
Multiple hazard detection sensors (smoke, heat, carbon monoxide, motion, door/window contacts) are integrated into a single alarm panel unit. This consolidation reduces the number of separate devices required while maintaining comprehensive hazard detection capability. The integrated design simplifies installation and reduces the quantity of individual components needed in the system.

AI summary
A Bluetooth/WiFi bridge includes a computing device in an interior of a dwelling with an internet-facing radio, and a second radio communicating with one or more non-internet-connected devices. The computing device provides for coordination of information flow between the two radios. The computing device is configured to enable the two radios to communicate and take incoming and outgoing information from one radio into a format that the other radio can transmit and receive. An audio sensor is configured to receive a sound from the one or more non-internet connected devices. The audio sensor being coupled to a logic circuit in the computing device. The internet facing radio is configured to communicate through a router to the internet and the non-internet devices connect to the internet via one of the radios through the computing device through the internet facing radio through the router to the internet, with the bridge communicating with a data center.
