摘要
以单片机为核心器件,以国产ZP-89型自动闭塞为原型,设计了使用低频信号调制载频650Hz的上行移频信号发生器。移频信号发生器实验仪以2FSK波形信号调制技术为理论依据,计算证明了单片机实现ZP-89移频信号发生器的可行性。通过系统设计仿真表明,实验仪产生的波形信号具有稳定性好、可靠性高等特点,在实验教学中起到了良好作用。
With the monolithic integrated circuit as the core device,and the domestic ZP-89 automatic block as the prototype,an uplink frequency shift signal generator by using the low frequency signal modulation carrier 650 Hz is designed.The experimental instrument of the frequency shift signal generator is based on the theory of 2FSK waveform signal modulation,and the feasibility of the ZP-89 frequency shift signal generator is proved by calculation.The system design and simulation show that the waveform signal produced by the experimental instrument has the characteristics of good stability and high reliability and plays a good role in experimental teaching.
