摘  要:
The supersonic detecting parking berth system based on AT89C51 microprocessor is introduced in this paper. The principle of supersonic range finding, the connection of hardware circuit between supersonic transmitter-receiver and AT89C51 microprocessor, and the software flow chart are analyzed with emphasis. Finally, the origin of range error and compensatory methods are pointed out. This system has already been applied in practice.
