摘　　要：针对地下位移测量传感器串的供电特点和要求,利用磁耦合谐振式无线电能传输技术,设计了一种无线电能传输装置,包含一个总控电源和多个无线电能传送节点。每个节点包括线圈回路、微控制单元、接收端电路、发送端电路、开关切换电路、无线通信模块。微控制单元根据通信模块接收到的指令,控制开关切换线圈与后端电路的连接。这使得每个节点都有3种工作状态,分别为接收状态、发送状态和中继状态。实验中,绕制不同的线圈,用网络分析仪测量其传输特性。接着将其与节点电路相连,验证无线电能传输装置性能,结果表明装置工作稳定可靠,满足传感器串的供电要求。A kind of wireless power transmission device is designed to include a total power supply and a plurality of radio energy transmission nodes by means of magnetic coupling resonant radio power transmission technology for the power supply characteristics and requirements of the underground displacement measurement sensor string. Each node includes a coil loop, a micro control unit,a receiver circuit, a transmitter circuit, a switch switching circuit and a wireless communication module. The micro control unit con-trols the connection of the switch switching coil and the back end circuit according to the instruction received by the communica-tion module. This allows each node to have three operating states, namely, receive status, send status, and relay status. In the ex-periment, the coil was wound and the transmission characteristics were measured with a network analyzer. Then, the coil is con-nected with the node circuit to verify the performance of the wireless power transmission device. The result shows that the device is stable and reliable to meet the power supply requirement of the sensor string.
