摘要

为延长视频胶囊内窥镜工作时间

提高体外接收视频质量

需降低胶囊内射频电路模块的功耗以改进发射电路的发射效果.针对上述问题

本文设计了胶囊内的射频电路模块和螺旋形发射天线

并使用ADS2011及HFSS对其进行仿真

最后通过实验对该设计进行验证.内窥镜胶囊进入活体动物(猪)胃肠道后

体外便携接收器接收到的视频图像质量较高

证明该改进设计可行.结果表明:当射频电路板的直径为9.8 mm

射频模块的工作频率为1.0 GHz

功耗为15.9 mW时

胶囊的工作时间为9.0 h

视频数据的无线传输速率达到30 frame/s(320240 pixel/frame).

Abstract

To prolong the worktime of the video capsule endoscopy and improve the quality of the video

lowering the power of the embedded radio circuit module inside the capsule is needed

which helps improve the radio effect.The embedded radio circuit module and helix antenna inside the endoscopy are designed

ADS2011 and HFSS are applied in simulation

and finally the experiments validate the design.The high quality video after the video capsule endoscopy entered the gastrointestinal (GI) tract of the live animal (pig) validated the feasibility of the design.The result indicates that the worktime of the endoscope is 9.0 h and the wireless transmitting rate reaches 30 frame/s (320 240 pixel/frame) when the diameter of transmission circuit board is 9.8 mm

work frequency is 1.0 GHz

and power is 15.9 mW.
