The Design And Implementation Of Ultrasonic Communication System Based On Oceanographic

With the vigorous development of China’s economy, people’s growing demand forenergy, land resources are being rapidly consumed, and therefore, we must find a new sourceof energy. As another major supplies store, marine has been aroused strong concern in variouscountries, including the technology research of seabed exploration and exploitation of oil andother resources became a hot topic. How effective and accurate access to informationresources of the seabed in order to better mining has become an important task forExploration of the Sea.The effective data communication of Marine exploration technology is extremelyimportant aspect.The traditional communication methods of it include cable communicationsand drilling storage. Cable communications is Light,flexible,and good performance, but it iseasy to break and has a high cost; Drilling storage has a low cost, a better flexibility, butpoor real-time. For the lack of traditional programs, the paper studies and analyzes thecurrent popular marine exploration technology and ultrasonic applications, compared todomestic and foreign research results,then proposes the application for communication designbased on ultrasound, to improve the current underwater submarine detection technology wasproposed based on situ sondes, which has replaced the traditional cable transmission, usingultrasonic communication methods, the probe sensor to the reliable real-time data transmittedto the receiving terminal. The article details the features and benefits of ultrasound, as wellas the key points and difficult used in communication, and analyzes the structure of thetransducer, the performance indicators. Which focuses on the use of ultrasound in the pipetransport feasibility analysis of the ultrasonic attenuation of the communication, thecommunication distance of the problem. In the actual design, discussed in detail the overallarchitecture of the system implementation and internal module choices and focus compared2FSK modulation using a digital baseband signal modulation and demodulation of the prosand cons of various ways, and ultimately the use of STM8micro-controller80K of the centerfrequency of the modulation data. Using D ayu ’s DYW-80piezoelectric ultrasonictransducers and ultrasonic electrical signal conversion, and impedance matching are analyzed.In addition, the system implementation is also applied to the power amplifier circuit, the pre-amplification circuit, and a band-pass filter circuit and other modules are described. Finally,ultrasonic data communication system is tested, the transducer transmit power up to10W.Error-free data transfer rate of up to500bps. Through tests, the system can effectively resist the external noise, ensuring stable transmission of data, with low energy consumption, lowcost, high stability properties.
