This article introduced one kind based on the AT89C51 monolithic integrated circuit ultrasonic ranging system,this system basis ultrasonic wave the principle of reflection which disseminates in the air,take the ultrasonic sensor as the connection part,surveys the distance using the monolithic integrated circuit technology use ultrasonic wave in the air time difference,thus has designed a set of ultrasonic waves examinations system.The full text begins partial mainly carries on the elaboration to between the system design mentality and the different plan comparison,behind a half part in detail introduced the system hardware design,the software design and various modules realization.After the realization work may use in to need to survey is away from the parameter each kind of application situation.
