Sensor Device Routing Biological Data via Segmented Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor systems face challenges in efficiently acquiring and transmitting biological information from multiple subjects, especially in disaster scenarios like evacuation sites, where preparing the same number of devices for data transmission is difficult, and broadcast communication raises concerns about personal information security.
Innovation Solution
A system comprising a sensor device with near-field communication capabilities that distinguishes between connection-type and broadcast-type communication, allowing specific biological information to be transmitted securely through a dedicated terminal and other information to be broadcasted to any terminal, ensuring reliable data transmission and privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If broadcast communication is used to transmit sensor information, then the system can operate without extensive device setup and multiple terminals can receive data, but personal information security is compromised
Solution Approach 1:
The patent segments sensor information into two categories: identification information (non-personal) and measurement information (personal). Identification information is transmitted via broadcast to multiple terminals without setup, while measurement information is transmitted only to the designated terminal device through connection-type communication, thus maintaining security while preserving ease of operation for non-sensitive data
Solution Approach 2:
The sensor device acts as an intermediary that selectively routes different types of information through different communication channels. It mediates between broadcast communication (for identification info) and connection-type communication (for measurement info), allowing the system to benefit from both approaches without their respective drawbacks
2Object-affected harmful factors
If connection-type communication is used to transmit sensor information, then personal information security is maintained, but the system requires extensive device setup and cannot be received by unspecified terminals
Solution Approach 1:
By dividing sensor information into identification and measurement components, the patent allows identification information to be transmitted via simpler broadcast communication to multiple terminals, reducing setup complexity for non-sensitive data while maintaining connection-type communication for sensitive measurement information
3Reliability
If the same number of devices are prepared for each subject in disaster scenarios, then reliable data transmission is achieved, but resource constraints in evacuation sites make this difficult
Solution Approach 1:
The sensor device is designed to perform multiple functions: it can transmit data via both broadcast and connection-type communication modes, and can serve multiple potential terminal devices simultaneously. This multi-functionality allows one sensor device to reliably serve multiple subjects without requiring a dedicated device for each subject, reducing the total number of devices needed in resource-constrained disaster scenarios

AI summary
A sensor device 50 includes: an acquisition unit that acquires biological information on a subject; a communication unit that performs near field communication; and a controller, in which the controller determines whether the acquired biological information is specific biological information, transmits the biological information to a server device via the communication unit by way of a first terminal device 10 in a case where the biological information is the specific biological information, and transmits the biological information via the communication unit by broadcast in a case where the biological information is other than the specific biological information to transmit the biological information to the server device by way of an unspecified second terminal device 20.
