摘要
基于磁场反馈技术,完成了无线信号传输装置的研制。主机以C8051F020为核心控制芯片,采用ASK方式进行信号调制;从机以PIC18F1220为核心芯片,采用FSK作为信号调制方式。系统利用磁场反馈耦合能量,基于装置的硬件特点设计了主从机的底层通信协议,实现了主机与无源从机之间的双向信号传输。
On the basis of magnetic field feedback technology, the wireless signal transmission device has been developed. The master＇s core chip was C8051F020 using concoct signals by the ASK; the slave＇s core chip was PIC 18F 1220 using concoct signals by the FSK. The system used magnetic feedback to couple the energy and designed the communication protocol of bottom layer according to the features of hardware circuit to realize the two-way signals transmission between the host and the passive slave.
