Capsule Endoscope RF Channel Control for High Frame Rate Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing capsule endoscope systems with a single radio frequency (RF) module are unable to meet the high throughput requirements for image transmission and magnetic field signal transmission simultaneously, especially when the frame rate increases or when the capsule endoscope is in different parts of the digestive tract with varying degrees of freedom and movement.
Innovation Solution
The implementation of a control method and system that utilizes multiple RF transmission channels, dynamically adjusting their activation based on the frame rate and location parameters to ensure efficient and adaptive data transmission, including the use of at least two or three RF channels for image and location parameter distribution, and utilizing a Bluetooth module for post-operation identification.

Engineering Contradiction Analysis
1Productivity
If a single RF module is used for all data transmission, then the device complexity is reduced, but the data throughput is limited and cannot meet high frame rate transmission requirements
Solution Approach 1:
The patent divides the data transmission function into multiple segments by using multiple RF modules. Each RF module is assigned to transmit specific types of data (images, magnetic field signals, or control parameters), allowing parallel transmission and increasing overall data throughput without requiring a single complex high-capacity module.
Solution Approach 2:
The patent implements dynamic activation of RF modules based on real-time transmission requirements. The control module activates only the necessary number of RF modules (one, two, or three) depending on the frame rate and data transmission needs, optimizing the balance between throughput capability and energy consumption.
2Measurement precision
If the frame rate is increased to avoid missing information in the esophagus, then the detection precision is improved, but the data transmission burden increases and cannot be handled by a single RF module
Solution Approach 1:
When high frame rate transmission is required, the patent segments the transmission load across multiple RF modules. The control module activates additional RF modules to handle the increased data volume, with each module managing specific data streams to maintain detection precision while avoiding single-module bottleneck.
Solution Approach 2:
The patent dynamically changes the operational parameters of the RF modules based on frame rate requirements. When frame rate increases, the system adjusts the number of active RF modules and their transmission parameters to match the increased data throughput demand, ensuring detection precision is maintained.
3Measurement precision
If magnetic field signals are transmitted in real time at high frequency, then the position detection accuracy is improved, but the transmission frequency requirement exceeds the capability of a single RF module
Solution Approach 1:
The patent segments the real-time signal transmission task across multiple RF modules. Magnetic field signals and other high-frequency data are distributed to different RF modules, allowing each module to operate at appropriate frequencies while collectively achieving the required high transmission frequency for accurate position detection.
Solution Approach 2:
The control module dynamically adjusts which RF modules are active based on real-time position detection needs. When high-frequency magnetic field signal transmission is required for accurate positioning, the system activates the necessary number of RF modules to maintain the required transmission frequency.
4Productivity
If multiple RF modules are activated simultaneously, then the data throughput is increased, but the energy consumption increases
Solution Approach 1:
The patent implements dynamic activation of RF modules based on real-time transmission requirements. The control module activates only the necessary number of RF modules (one, two, or three) depending on the frame rate and data transmission needs, optimizing the balance between throughput capability and energy consumption.
Solution Approach 2:
The system dynamically changes the operational state of RF modules based on transmission demands. When high data throughput is needed, multiple modules are activated; when throughput requirements are lower, fewer modules are activated, thereby optimizing energy consumption relative to productivity requirements.

AI summary
A control method and a control system for a capsule endoscope are provided. The control method comprises acquiring a frame rate of the capsule endoscope. The frame rate is the number of frames of images captured by the capsule endoscope per unit time. The control method further comprises controlling the number of radio frequency transmission channels that are turned on according to the frame rate. The number of radio frequency transmission channels that are turned on is at least two, and the radio frequency transmission channels transmit the captured images. The control method and control system for the capsule endoscope can adaptively distribute a plurality of radio frequency transmission channels according to the real-time position of the capsule endoscope, and further turn on the radio frequency transmission channels to transmit a plurality of signals synchronously or asynchronously.
