Design and manufacture of a wind speed measuring
instrument
Abstract
The measurement of wind speed and direction is of great significance in
meteorological forecasting, environmental monitoring, wind power generation,
aerospace and other fields. With the development of sensor technology,
microprocessor technology and network communication technology, compared with
traditional manual observation, digital and intelligent meteorological instruments have
great advantages in observation accuracy, speed and stability. Therefore, it is of great
significance to design digital meteorological instruments, especially portable and
miniaturized instruments. Although the current wind speed and direction information
can be known through weather forecast, However, these are all in a large range and
cannot sense the wind speed and direction of a local area. Therefore, this paper
focuses on the design of wind speed and direction indicator.
The design and implementation of the wind speed and wind direction instrument
based on the single chip computer. The whole system includes the minimum system
STC89C52, RM-FS-N01 wind speed sensor, RM-FX-N01 wind direction sensor of
the single chip computer. The data collected by the pressure sensor is transformed and
transmitted to the single chip computer for processing, and then the measured wind
speed value is displayed on the LCD screen. For the wind direction system, the
encoder is used to measure and collect signals within the range of 0~360 °. Under the
condition of multi-turn rotation, the single-turn automatic zeroing can be realized. The
data is converted and processed by the single-chip microcomputer. The measured
wind direction is also displayed by the LCD. The software part is designed in modular
programming mode to facilitate the maintenance and improvement of the program.
