The invention discloses an interface simulation system and method of a CBTC (Communication Based Train Control) system based on discrete I/O (Input/Output) control. Theinterface simulation system includes: a relay; a data acquisition card; a trackside interface preprocessing module and a vehicle-mounted interface preprocessing module which can load and initialize the connection with a corresponding system according to the system of the tested equipment; an interface information conversion module which can collect the bidirectional digital signal and convert the bidirectional digital signal into a general data format; an interface information mapping execution module which can realize mapping from a physical state value of the tested equipment to a relay state value and mapping from the relay state value to a computer digital signal; a transponder message execution module which can realize dynamic calculation and real-time processing of the transponder; and a fault injection module which can realize simulation
