摘要

针对图像胶囊内窥镜受到能量限制而工作时间较短的问题

基于图像胶囊在人体肠道蠕动的速度设计了一种间歇工作模式的微型化、低功耗图像胶囊内窥镜。采用霍尔开关代替干簧管作为电源总开关

进一步降低了图像胶囊的体积。通过对电池电源模块、模拟开关电路和软件进行设计研究

实现了无线发射和照明电路的间歇供电和图像传感器的间歇休眠。动物实验验证了整个系统的工作时间和可行性。结果表明

整个系统的尺寸仅为

12 mm25 mm

1 s间隔工作模式下系统的工作时间超过9 h。

Abstract

As the image capsule endoscopy is limited by the energy and it has short working time

this paper designs a miniature intermittent working image capsule endoscopy with low power consuming according to the speed of image capsule's peristalsis in human intestine. The Hall switch was designed as the main power supply switch instead of reed switch to further reduce the volume of the image capsule. A battery power supplies module

an analog switch circuit

and a software were developed to realize the intermittent power supplies of wireless transmitting and Light Emitting Diode(LED) circuits and the sleep mode of an image sensor. The clear images were obtained successfully

and the tests and animal experiments were performed to prove the work time and feasibility of the whole system. Obtained results show that the total size of the system is only

12 mm25 mm

and the work time is more than 9 h in one second intermittent working mode when the modules are connected.
