Abstract
The invention provides an ultrasonic data transmission method. After A/D (analog to digital) conversion is performed on original data information to be transmitted, ultrasonic frequency carrier electric signals comprising the original data information are formed through a modulation/oscillating circuit producing the ultrasonic frequency; after power amplification, the ultrasonic frequency carrier electric signals carrying the original data information are converted into ultrasonic signals to be transmitted to a steel tube through an ultrasonic transducer closely contacted with the steel tube; the steel tube is used as a data transmission body; in the other position of the steel tube, the ultrasonic signals which contain the original data information and are transmitted by the steel tube are received and converted into electric signals by a pickup closely contacted with the steel tube; then after filtering, detection and amplification, the transmitted original data information is reduced, so that transmission and communication of data are realized. According to the method, remote nonlinear transmission of signals can be performed under conditions of oil-gas wells and the like, the erection cost and the post-maintenance cost are low, and the signal loss is small.
