Voice-Call Gateway Integrating Sensor Networks for Emergency Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sensor network systems do not allow residents to report emergency situations or abnormalities by voice to security service providers while they are present in the residence.
Innovation Solution
A voice-call system comprising a gateway, voice-call terminals, and a server device that enables residents to notify security service providers through a simple voice operation, using short-range radio communication and public telecommunications networks for data transfer, allowing both unicast and multicast communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sensor network system is used to collect monitoring information, then monitoring capability is improved, but voice notification capability is lost
Solution Approach 1:
The patent combines the sensor network system with a voice call system by integrating a voice call terminal and gateway into the monitoring system. The gateway collects monitoring information from sensor nodes while simultaneously enabling voice communication between residents and security personnel, thus merging monitoring and voice notification capabilities into a unified system.
Solution Approach 2:
The gateway device performs multiple functions: it collects monitoring information from sensor nodes, manages voice calls between residents and security personnel, and coordinates communication between different system components. This multi-functionality resolves the contradiction by enabling both monitoring and voice notification through a single integrated device.
2Quantity of substance
If conventional sensor network systems are used, then monitoring information collection is achieved, but emergency notification efficiency is reduced
Solution Approach 1:
The system enables continuous voice communication during emergency situations, allowing residents to notify security personnel immediately without interruption. The voice call terminal and gateway maintain continuous connectivity, ensuring that emergency notifications are transmitted without delay, thus improving notification efficiency while maintaining comprehensive monitoring.
Solution Approach 2:
The gateway acts as an intermediary that bridges the sensor network system and voice communication system. It collects monitoring information from sensors and simultaneously facilitates voice calls, enabling efficient emergency notification by mediating between different communication channels and eliminating delays associated with conventional sensor-only systems.
3Ease of operation
If voice call functionality is added to monitoring system, then notification capability is improved, but system complexity increases
Solution Approach 1:
The patent merges the voice call functionality with the existing sensor network system by integrating a voice call terminal and gateway into the monitoring infrastructure. This consolidation achieves notification capability while minimizing additional complexity by sharing existing system components and infrastructure.

Function Achieved in This Case
Enables residents to report emergencies or abnormalities by voice with ease, facilitating effective communication between residents and security service providers, enhancing security and response efficiency.
Implementation Method 1
a first speech signal of the resident converted into an electric signal by the microphone
Implementation Method 2
output, by voice from the speaker, a second speech signal transmitted from the monitoring device

AI summary
A CMS server 5 relays the communication between a gateway 3 disposed in a residence 100 and a monitoring device 4 used by a company that provides security service. When a resident staying in the residence 100 operates an operation section of a voice-call terminal 1 once, the voice-call terminal 1 transmits, to the gateway 3, a speech signal that is input from the resident into a microphone. This speech signal is transmitted from the gateway 3 to the monitoring device 4 via the CMS server 5, and is output from the monitoring device 4. The speech signal that has been transmitted from the monitoring device 4 to the voice-call terminal 1 via the CMS server 5 and gateway 3 is output from a speaker of the voice-call terminal 1.
