The Application of Embedded Intelligent Ultrasonic Distance Measurement technology in the Well Logging Instrument

摘要

In this paper an intelligent ultrasonic distance measurement transducer integrating the distance measuring module based on the emission and receiving of ultrasonic with control module based on S3C2410 and communication module based on protocol RS232 is put forward.The module of temperature compensation circuit is to improve the precision.The structure of ultrasonic measuring module driver program is analyzed in embedded Linux system.Also,the transmitting/receiving circuits were designed.The echo signal would be processed by S3C2410 processing electronics.The control of transducer can be realized by the communication between the transducer and upper computer of the well logging instrument.
