摘　　要：本设计利用ATMEL公司AVR系列ATmega128单片机的控制调频电路来调制系统的工作频率,实现对口腔CBCT系统X射线球管电压的精确控制和调节,同时还实现了系统的人机交互、数据存储和传输、数/模转换、串口通信等功能。该控制电路硬件设计简单可靠,易于实现;软件开发方便灵活,实现了预期的功能。ATmega128 microeontroller of AVR series from ATMEL Corporation is used in this design. This mierocontmller is used to control the frequency modulation circuit to modulate the frequency of the system, so that the precise control and modulation of the X-Ray tube voltage in dental CBCT system can be realized. Besides,functions such as human-computer interaction ,data storage and transmission,AD conversion and communication with serial port are all realized.The hardware design is simple,reliable and easily to be implemented. The software development is convenient and flexible. This eontro｜ system achieves expected function.
