本发明公开了一种面向本安电源的电能/信号同步传输系统及方法，传输系统包括同步降压斩波电路一、同步降压斩波电路二、信号发生系统一、驱动电路一、信号解调系统一、信号发生系统二、驱动电路二、信号解调系统二。本发明采用了新型的信号传输控制方式，在负载上产生纹波，通过调制解调负载上产生的电压纹波实现信号的双向传输。当开关管关断时依然能够传输信号，提高了信号传输的精度与速度。信号传输过程中负载纹波依然较小，不会对能量的传输造成较大影响。 The invention discloses an intrinsic safety power supply oriented electric energy/signal synchronous transmission system and method. The transmission system comprises a synchronous buck chopper circuit I, a synchronous buck chopper circuit II, a signal generation system I, a driving circuit I, a signal demodulation system I, a signal generation system II, a driving circuit II and a signal demodulation system II. A novel signal transmission control mode is adopted, ripples are generated on the load, and two-way transmission of signals is achieved by modulating and demodulating the voltage ripples generated on the load. And when the switching tube is switched off, the signal can still be transmitted, so that the signal transmission precision and speed are improved. Load ripples are still small in the
