The invention relates to the technical field of communication, and discloses an electronic detonator initiator communication system and method based on 2FSK, and the system comprises a modulation module which is used for carrying out frequency-shift keying modulation on communication data to be sent by an initiator, generating a modulation signal composed of two kinds of carrier waves with different frequencies, and changing the frequency every modulation time, in each period of modulation time, the digital signal with low carrier frequency is 0, and the digital signal with high carrier frequency is 1; the signal conversion module is electrically connected with the modulation module and used for converting the modulation signal into a double-path differential signal, and the double-path differential signal is transmitted to an electronic detonator through two paths of blasting buses and blasting leg wires respectively; and the control module is electrically connected with the modulation module and is used for
