Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current steering communication systems for radio-controlled objects, such as model planes, lack a two-way communication capability, leading to communication jamming and the inability to accurately transmit telemetry data from multiple sensors mounted on luxury or large planes.
Innovation Solution
A steering communication system that includes a steering communication device and steered-object communication devices, which use pairing-setup signals and identification numbers to enable individual transmission requests and responses for telemetry data, preventing communication jamming by controlling transmission timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a two-way communication system is constructed with one steering communication device and multiple steered-object communication devices, then telemetry data can be obtained from each device, but communication jamming occurs when all devices transmit simultaneously
Solution Approach 1:
The patent implements periodic action by assigning different transmission timing to each steered-object communication device. The control unit transmits telemetry data requests at predetermined timing for each device individually, and each device transmits its data at assigned time slots. This periodic, time-division approach prevents simultaneous transmission conflicts while enabling all devices to communicate telemetry data reliably with the steering communication device.
Solution Approach 2:
The patent applies segmentation by dividing the communication process into separate time slots for each steered-object communication device. Instead of allowing all devices to transmit simultaneously, the system segments the transmission timeline so that each device has its own designated time window for data exchange. This segmentation eliminates communication jamming while maintaining the ability to collect data from all devices.
2Adaptability or versatility
If traditional one-way communication system is used, then device complexity is reduced, but two-way communication capability and telemetry function cannot be achieved
Solution Approach 1:
The patent applies universality by designing the steering communication device and steered-object communication devices with multi-functional capabilities. The same communication hardware is used for both steering control signals and telemetry data transmission. The control unit within each device handles multiple functions including receiving steering commands, transmitting sensor data, and managing time-division multiplexing, thereby achieving two-way communication without requiring separate dedicated hardware for each function.
Data Source
AI summary
The present invention provides a steering communication system being able to individually obtain a telemetry data from a steered-object communication devices mounted on the steered-object. An arbitrary identification number assigned to a plurality of steered-object communication devices mounted on a steered-object at the time of pairing-setup is associated with the equipment ID of a pairing object. When performing transmission request of a telemetry data, a steering signal adding the transmission request information and the own identification number is transmitted. The steered-object communication device judges signal classification of the inputted control signal. When the steering signal adding transmission request information and the own identification number is inputted, the steered-object communication device transmits a telemetry data signal adding the telemetry data as an answer signal to a steering communication device.
