Telemetry System Hardware Design And Implementation Of Wireless Data Transmission Of Underwater Explosion Pressure

This paper mainly discusses about the hardware design and realization methods of the subaqueous explosion pressure remote measuring system. The emphases are the hardware designs and realizations of the data acquirer and the microprocessor control system.Chapter 1 introduces the background and the content of this paper. Chapter 2 introduces the design thinking of the subaqueous explosion pressure remote measuring system, and its structure, the course of the subaqueous explosion, and its measuring demand.Chapter 3 is the first keystone of this paper. It studies the key technologies about the subaqueous explosion pressure measuring. Such as sensor technology, time-domain sampling and frequency-domain sampling technologies, wireless data transfer technology. FSK. Nyquist sampling theorem.Chapter 4 is the second keystone of this paper. It mainly discusses the design and realization of the data collecter, the control technology of the double microprocessors, the design and realization of the single circuit. It mainly discusses ADC and the relationship between the number of ADC' binary digit bits and the pressure measuring precision of this system, educes the conclusion that the effect caused by the number of ADC' binary digit bits on the pressure measuring precision of this system can be ignored.Chapter 5 analyses the character of this system, introduces the precision experiment, and discusses the stability of this system.Chapter 6 introduces my project to improve this system and my gains in manufacturing and developing this system.
