Data Transfer Device Inhibit Signal Duplicate Degree Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing data transfer systems, when multiple devices receive sensor information, there is a risk of duplicate registration requests being sent to a management device, leading to inefficient communication and inaccurate positioning, as devices distant from the sensor may transfer information with their own position information instead of the closest device's.
Innovation Solution
A data transfer program that uses inhibit signals to determine which device closest to the sensor should transmit position information to the management device by managing duplicate degrees and associating them with transmission sources, ensuring only the device with the highest duplicate degree registers the position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple devices transfer sensor information to the management device, then the position information coverage is improved, but duplicate registration requests increase causing communication inefficiency
Solution Approach 1:
The system performs preliminary actions by having devices exchange inhibit signals before actual position information registration. Each device calculates its duplicate degree (number of received inhibit signals) and compares it with others. The device with the highest duplicate degree (indicating it received the most inhibit signals from distant devices) is predetermined as the registration candidate, preventing duplicate registration requests before they occur.
Solution Approach 2:
The system implements feedback mechanisms where devices transmit inhibit signals to neighboring devices, and each device monitors how many inhibit signals it receives. This feedback loop allows devices to determine their relative positions and identify which device should register position information based on the duplicate degree metric, ensuring only the most appropriate device communicates with the management device.
2Quantity of substance
If devices distant from the sensor transfer position information, then more position data is collected, but the position accuracy deteriorates
Solution Approach 1:
The system applies local quality by making each device evaluate its own local situation - specifically, how many inhibit signals it receives from other devices. The device that receives the most inhibit signals (has the highest duplicate degree) is identified as the one closest to the sensor. This local evaluation ensures that position information is registered by the device with the best local position quality without requiring global coordination.
3Loss of information
If all receiving devices attempt to register position information, then position information completeness is improved, but redundant communication increases
Solution Approach 1:
The system extracts the essential function of position registration from all devices and concentrates it in only one device - the one with the highest duplicate degree. By taking out the registration function from the group and assigning it to a single selected device, the system prevents redundant communication while ensuring position information completeness is maintained through the inhibit signal exchange mechanism that identifies the best registering device.
Data Source
AI summary
A data transfer method includes: executing a process that stores sensor information including duplicate degrees and position information, the duplicate degrees indicating an amount of computers as transmission sources of inhibit signals received by the first computer; executing a process that transmits the inhibit signal including the duplicate degree in the sensor information to a computer that is present in a position to which direct communication via the short-distance radio communication is possible; executing a process that stores the duplicate degree in the inhibit signal, associates the duplicate degree with the transmission source of the inhibit signal, and increases the duplicate degree in the sensor information; and executing a process that transmits the position information in the sensor information to the management device in a case where the duplicate degree in the sensor information is higher than the duplicate degree associated with the transmission source of the inhibit signal.
