Design of Human Gastrointestinal Tract UWB Data Transmission System Based on STM32

摘要: 胃肠道疾病如胃癌和肠癌已经成为多发病和常见病，现有的胶囊内窥镜通信技术由于带宽的限制难以实现高质量的图像实时监测。本文从实用角度出发，采用超宽带通信技术，利用STM32单片机和相应的超宽带芯片来实现传输数据。系统由STM32芯片、DW1000芯片与天线等部分构成。在该系统中，通过STM32芯片获取图像并进行处理，利用DW1000芯片和相关天线来传输数据到PC端，用户可以在上位机中显示相关的图像，提高了传输图像的速率与质量。本系统设计解决了传统窄带通信的带宽限制，有效地降低内窥镜的功耗，提高续航时间，为胶囊内窥镜的图像实时传输提供了解决方案。

Abstract: As gastrointestinal diseases such as gastric cancer and intestinal cancer have become more common and recurring, real-time image monitoring of high quality is impractical for the existing capsule endoscope communication technology because of the limitations of bandwidth. From the practical point of view, this paper adopts UWB communication technology to realize data transmission through STM32 microcontroller and the corresponding UWB chip. This system, composed of STM32 chip, DW1000 chip and antenna, achieves images acquisition and processing through STM32 chips and realizes data transmission to the PC through DW1000 chips and related antenna so that relevant images are accessible to users to ensure image transmission in high quality and high speed. The system proposed not only solves the traditional narrowband communication bandwidth limitations, effectively reduces the power consumption of endoscope and improves the battery life, but also provides a solution for real-time image transmission of capsule endoscope.
