| Abstract: |
| In view of the long detection cycle, low manual inspection efficiency and low simulation accuracy of traditional automatic weather station sensor signal simulators in the comprehensive inspection process of ship weather instruments, the lack of related motion compensation algorithms makes such systems unsuitable for marine ship application environments. The high-precision signal sampling circuit, signal output, software filtering and motion compensation of the meteorological element sensor are studied. Through the analysis of the principles of sensors and ship weather instruments, the sampling circuit, signal simulation circuit, touch screen, GPS and electronic compass sampling and simulation circuit of various meteorological parameters were designed, and the motion compensation model test was carried out during the offshore test, and based on The STM32 microcontroller carried out the system testing experiment of the instrument. Research and test results show that: the system has low power consumption, high reliability, high precision, can be applied to the marine environment, and has the functions of real-time positioning of ships, real-time simulation and collection of meteorological elements, and motion compensation, and the accuracy of the system is in motion After compensation, the system measurement variance is 0.0193, and the accuracy is improved to close to the true value, which all meet the standards of "Marine Survey Specification Part 3: Marine Meteorological Observation". |
