Chapter 28 Temperature Monitoring Data Transmission Through Metallic Barrier Based on Ultrasonic Technology

摘要

A novel temperature monitoring prototype through metal barrier based on ultrasonic waves is introduced in this paper. By using this promising technique, temperature sensor data can be transmitted through a metal barrier without physical penetrations. The structure of the temperature monitoring prototype, the reliable data trans-mission modulation schemes and the coding and decoding for temperature signal transmission through-metal-wall are presented. Finally temperature monitoring experiments are carried out and the results show that temperature sensor data can be transmitted through the metal barrier at a speed of 10 Kbps. The method presented is proved to have a potential engineering application in enclosed metal structure monitoring without penetration.
