Discussion About The Field Calibration Method Of Marine Automatic Weather Station

In order to made sure the unity of Marine Automatic Weather Station measurementvalues and accurately; for further development of relevant metrological verification /calibration standard, the preliminary theoretical study and field test validation. The articleintroduces the special value of the marine ocean temperature, salinity, the definition ofrehabilitation methods and interpolation formula is a brief introduction to the SouthChina Sea area in the distribution of automatic observation stations, apparatusspecifications, with the observation and measurement accuracy factor Etc., of varioussensors with different types of works, measurement properties.Briefly in the use of marine automatic weather station temperature and humidity,temperature and salinity, wind, barometric pressure, rainfall sensor classification,structural features, working principle; with marine measurement instruments andequipment calibration standard control the progress of the latest scientific research,according to their works Different options meet the required standards of measurementfor value transfer device and major equipment; brief introduction to the standardrequirements of the technical parameters of devices and supporting equipment, technicalparameters. Reference to relevant elements of the verification procedures of measuringinstruments with characteristics of the environmental conditions on-site calibration, setup a practical on-site calibration parameters, design the site calibration process, theresulting field of the automatic weather station sensor calibration method, citing the sceneto carry out calibration Examples of activities. The final analysis of the calibration of thesensor field of uncertainty introduced by the source and quantity, and to analysisuncertainty components related to the form instance Uncertainty of calibration resultswere in accordance with the evaluation method of class A and class B assessmentMethods are given the size of each component of uncertainty, and ultimately calculate thevarious types of sensor field calibration uncertainty size.Final assessment by the sensor the size of the expanded uncertainty, we know thatthe proposed on-site calibration method, simple operation and precise value transfer,calibration data are accurate and reliable. Has in the marine industry to promote the useof practical significance and strong promotion of marine automation equipment enhance the quality of observations, can our marine environment monitoring and observationtechniques to improve measurement and calibration to provide strong technical support.According to the proposed operation of the sensor calibration method to calculatethe results of its on-site calibration laboratory calibration uncertainty is very close to theuncertainty of results. It can be seen with the development of calibration, is now availableat the work site of each sensor using the calibration approach to value transfer conditions.
