【摘要】 本文介绍了金属管道中探测作业机器人微波输能系统,它包括激励装置和接收装置。该系统利用波导传输机理,较好地实现了高功率的微波在金属管道传输过程中的极化和能量传输的稳定性问题,微波能量由管道中的机器人供能单元——整流天线接收并整流成直流。针对直径20 mm的工业用不锈钢管道,实验测得其传输损耗为1.3 dB/m,表明该管道可用作微波传输线向微机器人供能。本文设计的整流装置采用四个HP-HSMS-8102肖特基二极管组成四个并联的倍压电路,在24.5 dBm输入功率下(直流负载为300W)测得其整流效率达到了45.4%。更多还原

【Abstract】 This paper introduces a microwave energy supply system for in-pipe inspect micromachine. The system keeps the microwave transmission with single TE11o mode and solves the problem resulting from polarization rotation. The micromachine energy supply unit (rectenna) receives microwave energy and then converts it into DC electric energy. The experimental results have shown that the attenuation of industrial stainless pipe of 20 mm diameter is about 1.3 dB/m, Thus the pipe is suitable for supplying power to micromachine. The circuit is composed of four doubler circuits using four Schottky barrier diodes (HP-HSMS-8102). A RF-to-DC conversion efficiency of 45.4% has been achieved at an input power level of 24.5 dBm with 300W DC load.更多还原
