The invention relates to the technical field of equipment testing, and provides an ultrasonic sensor self-checking system and method and an acoustic emission leakage monitoring system.The ultrasonic sensor self-checking system is used for conducting excitation detection on an ultrasonic sensor and comprises an excitation signal generator, a signal analyzer and an ultrasonic signal mixed magnetic ring network; the excitation signal generator sends an excitation signal to the ultrasonic sensor and the signal analyzer through the ultrasonic signal mixed magnetic ring network; the ultrasonic signal mixed magnetic ring network eliminates the excitation signal received by the signal analyzer; the ultrasonic sensor generates a stress signal and sends the stress signal to the signal analyzer; and the signal analyzer receives and analyzes the stress signal to obtain a self-inspection result of the ultrasonic sensor. According to the ultrasonic sensor self-checking system, faults of the ultrasonic sensor are eliminated
