Development of Telemetry Wave Instrument Based on MEMS Sensing Technology

Abstract

Regarded as the most important object of marine environmental monitoring, wave condition especially the height, period measurement technology has comprehensively involved various means during the deepening of wave research. Among many wave measuring methods, wave measuring buoy is recognized as the most direct and accurate equipment. Acceleration integration and turbine flow meter constitute the traditional mainstream of wave testing. GPS and MEMS sensors have been developed to measure waves in recent years. Because buoy is a wave measuring equipment that directly contacts the sea surface, its measuring accuracy is higher than that of other wave measuring methods, so it is also considered by foreign countries as the most direct and accurate wave measuring equipment. In this paper, GPS and MEMS sensing technology are mainly used to analyze the wave height and period measurement. At the same time, the main development process of the wave height gauge is introduced extensively. Finally, the accuracy and repeatability of the wave height meter are tested by means of walking crane, certificated meter ruler and stopwatch. The test results show that it can meet the relevant standards of wave measurement and monitoring. On this basis, the sensor is tested in the South China Sea, and the reliability of the instrument is further verified. In one word, the paper can provide theoretical basis and technical support for the research and development of wave measurement equipment and promote the practical application in the field of wave condition monitoring.
