Server Position Estimation for Transport Equipment Device Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in transport equipment, such as aircraft, lack user-friendliness in network connections between transport equipment and external devices, particularly in determining the optimal connection priority and listing connectable devices for passengers.
Innovation Solution
A server system with a signal-intensity receiver, storage, and controller is implemented in transport equipment, capable of communicating with multiple radio communication devices and input/output terminals. It estimates the position of external devices based on signal-intensity information and position data, determining connection priorities and transmitting a list of connectable devices to the user's terminal.

Engineering Contradiction Analysis
1Ease of operation
If the system provides a list of all detectable external devices, then the user can see all available options, but the user cannot easily identify which device is most suitable for connection
Solution Approach 1:
The server performs preliminary actions by estimating the position of external devices based on signal intensity information before the user makes a connection decision. It pre-calculates connection priorities and prepares the connectable-device list with ranking information in advance, so when the user views the list, the most suitable devices are already positioned at the top, eliminating the need for users to manually evaluate multiple devices.
2Measurement precision
If the system estimates device position using signal intensity from multiple radio communication devices, then the position estimation accuracy improves, but the system complexity increases
Solution Approach 1:
The server acts as an intermediary between the radio communication devices and the input/output terminal. It receives signal intensity information from multiple radio communication devices, performs the complex position estimation calculations centrally, and then provides the results to the user interface. This intermediary approach allows the system to achieve high measurement precision through multi-device signal processing without requiring each individual device to be complex.

AI summary
The server is disposed in transport equipment having a plurality of seats and is capable of communicating with at least three radio communication devices and an input/output terminal. The server has a signal-intensity receiver, a storage, and a controller. The signal-intensity receiver receives signal-intensity information on radio waves of an external device. The storage stores first position data indicating a position corresponding to each of the radio communication devices, and second position data indicating a position corresponding to the input/output terminal. The controller receives a connection request for communicating between the radio communication devices and the external device. The controller estimates a position of the external device based on the signal-intensity information and the first position data, determines a connection priority of the external device based on the estimated position and the second position data, and transmits a connectable-device list based on the connection priority to the input/output terminal.
