Abstract:

The STM32 series MCU is far better than the C51 series single-chip microcomputer in terms of operating speed, storage space or functional interface, and using STM32 chip can improve the overall performance of meteorological data online monitor. Internal structure and overall design of the monitor are firstly introduced. Secondly, the cyclic sampling design is carried out based on the description of the meteorological sensor working principle and signal type characteristics. Finally, the data quality control method and storage strategy are introduced. Test results show that the monitor achieves its design goal. Sampling performance of each channel and measurement performance of each meteorological element can meet the needs of meteorological data online monitoring. This design can provide reference for the development of other small environmental detection equipment based on STM32.
