An ultrasonic wave and carrier wave rail breaking monitoring system comprises a steel rail, a control circuit board, a data transmission module and a monitoring center. Detachable ultrasonic broken rail monitoring devices are evenly arranged on the steel rail, each ultrasonic broken rail monitoring device comprises two sets of ultrasonic transducers arranged in a mirror image mode and a clamping device installed between the ultrasonic transducers and the steel rail in a fastened mode, and each ultrasonic transducer comprises an ultrasonic excitation module and an ultrasonic receiving module. The excitation module can send out ultrasonic signals propagating along the steel rail at set intervals, the receiving module transmits the ultrasonic signals to the monitoring center through the data transmission module after receiving the ultrasonic signals, and the monitoring center analyzes data in a background mode to judge the state of the steel rail in the area. The control circuit board and the data transmission module are provided with a switching power supply which is electrically connected with the control circuit board and the data transmission module.
