A master-slave compatible PDC system, comprising a master sensor, at least one slave sensor, which comprises an ultrasonic IC, a boost drive module, and a second ultrasonic transducer; the CPU module drives the first ultrasonic transducer via the master drive module, the first ultrasonic transducer amplifies and transmits echoed signals to a A/D conversion module of the CPU module via a master amplifier module, the CPU module drives the ultrasonic IC of the corresponding slave sensor via a slave drive module, the ultrasonic IC drives the second ultrasonic transducer via the boost drive module, and the second ultrasonic transducer feeds back the echoed signal to the A/D conversion module of the CPU module via the ultrasonic IC. In the Invention, the ultrasonic IC is employed for each slave sensor, enabling a farther detection distance and stronger anti-interference capability of the whole system.
