Therefore, it is a booming and technology and industry have unlimited prospects. The design introduces the principle of the ultrasonic distance measurement instrument based on SCMC-controlled: AT89S52 controls timers to produce the ultrasonic wave pulse and time,count the time of ultrasonic wave spontaneous emission to receive round-trip,thus obtains the measured distance.And the temperature compensation adjustment is used in the data processing, with four LCD nixie tubes display distance or temperature by switching. It has given the system constitution, the circuitry and the programming. The instrument system has features: ease of control, stability of operation, highness of precision and distinctness of programme process ,etc. After the realization of the works can be u...
