| 摘 要： | 针对无源感应数据传输系统工作环境中金属涡流损耗大、接收天线尺寸小等条件造成的数据传输距离短的问题，在发射机中设计了C类功率放大器，对环形发射天线进行了改进，接收机中设计了稳定的升压电路，选用了低功耗的PIC16LF877A处理器，通过这些方法增大了数据传输的距离。所设计的系统性能稳定，数据传输距离为15cm，并符合实时性和可靠性的要求。

| Abstract: | The data transmission distance of passive inductive data transmission system is short due to the great metal eddy current loss and the small size of receiver antenna in application environment. To overcome the problems, a class C power amplifier was designed and the circle transmitting antenna was improved in the transmitter, while a steady electric charge pump circuit and a low power consuming processor PIC16LF877A were adopted in the receiver. The transmission distance has been increased via these methods. The transmission distance of the designed system is 15 cm, which can transmit data reliably in real time with steady performance. |
