文中的无线电遥控系统是基于高频锁相环NE564设计的多控制对象系统。使用NE564设计发射机和接收机,采用FM调制脉冲信号和FSK方法解调,以8051单片机编码和解码,通过PT2262芯片将接口并串行转换,使用PT2272芯片将解调到的串行数据转换为并行数据,实现对八个目标的控制,并且配合LCD显示。系统结构简单小巧,有友好的人机界面,性能稳定,功耗低,控制距离远。
The text of the radio remote control system is based on high-frequency PLL designed NE564 multi-control object system. Using NE564 transmitter and receiver design, the use of FM modulation pulse signal and FSK demodulation method to 8051 single-chip encoding and decoding, through the PT2262 chip interface and serial conversion, the use of PT2272 chip will be demodulated into serial data into Parallel data, to achieve the control of eight goals, and with the LCD display. System structure is simple and compact, friendly man-machine interface, stable performance, low power consumption, long distance control.
