Ultrasound Wireless System for Sensor Data Transmission of Ultra-Thickness Plank

Abstract:

In this paper, Ultrasound Wireless System is introduced for wireless communication between the sides of ultra-thickness plank without breach of the structure. This system could be applied in the plank of the difference material of metal or non-metal and in environment in which high seal condition is required in uttermost, for instance ultra-pressure, radiation and virulent test. In this wireless system, the ultrasonic telemetry using single pulse for driving and receiving PZT has been designed and built to demonstrate the ability of the ultrasonic telemetry. This paper describes the designed transmitting circuit and receiving circuit and the results of a pilot set up. The driving characteristics and frequency response of PZT was analyzed and tested. It is very important that the transmitting circuit and receiving circuit were designed according to the frequency characteristics of the PZT and coupling, that is, the width of pulse and frequency of signal for the driving PZT must be properly chosen. It has been shown that communication of sensor signals can be made at two sides of steel enclosed container using PZT as ultrasonic transmitters and receivers.
