BLE Beacon Application Identifier for Working Machine Data Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems for working machines lack efficient methods to transmit application identifiers and data between communication devices and mobile terminals, particularly using Bluetooth Low Energy (BLE) technology, which limits seamless application activation and data exchange.
Innovation Solution
A communication device connected to a working machine transmits an application identifier via BLE to a mobile terminal, activating the corresponding application and subsequently transmitting data related to the working machine, facilitating efficient data exchange and application management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If application identifier is transmitted via BLE beacon from working machine to mobile terminal, then application activation and data exchange efficiency is improved, but device complexity and communication protocol requirements increase
Solution Approach 1:
The communication process is segmented into distinct phases: beacon transmission phase (application identifier only), connection establishment phase, and data transmission phase. This segmentation allows the system to use simple BLE beacon technology for initial contact while reserving more complex communication for when needed, resolving the contradiction between efficiency improvement and device complexity.
Solution Approach 2:
The system performs preliminary action by transmitting the application identifier via BLE beacon before actual data exchange requirements arise. This allows the mobile terminal to pre-activate the appropriate application and prepare for data reception, improving overall system responsiveness without requiring the working machine to have complex data transmission capabilities ready in advance.
2Reliability
If data transmission is performed after mobile terminal activates application, then data exchange accuracy and relevance are improved, but communication time and latency increase
Solution Approach 1:
The mobile terminal activates the relevant application in advance upon receiving the BLE beacon, before actual data transmission begins. This preliminary action ensures that the data receiving infrastructure is ready and configured correctly, eliminating setup delays during actual data exchange while maintaining data accuracy and relevance.
Solution Approach 2:
The system implements feedback mechanisms where the mobile terminal confirms application activation status to the working machine. This feedback loop allows the system to verify that the correct application is active before initiating data transmission, ensuring data exchange accuracy while minimizing unnecessary delays through efficient confirmation protocols.
