Abstract

The invention relates to a meteorology apparatus instrument and especially discloses an ultrasonic wave wind speed anemoscope and a corresponding multiple meteorology parameter measuring instrument. The wind speed anemoscope comprises four ultrasonic sensors which are arranged on a same horizontal plane. The four ultrasonic sensors are controlled by a single chip microcomputer operation control circuit to send or receive an ultrasonic wave. Time between the ultrasonic wave sending and the ultrasonic wave receiving can be recorded so that an actual wind speed and a wind direction can be calculated. Wind cup wearing caused by long-time mechanical rotation can be avoided so that a service life can be prolonged. The multiple meteorology parameter measuring instrument integrates a plurality of function modules, such as the wind speed anemoscope, a temperature sensor, a humidity sensor and a pressure sensor, through the single chip microcomputer operation control circuit so that the overall structure of the instrument is concise and compact. Therefore, installation and usage are more convenient. A plurality of mechanical movement parts in a traditional measuring system are not needed. Stability and reliability of the instrument can be improved.

Description

Technical field [0001] The invention belongs to the technical field of meteorological instruments and meters, and specifically relates to an ultrasonic wind speed and direction meter and a corresponding multi-meteorological parameter measuring instrument. Background technique [0002] Temperature, humidity, atmospheric pressure, wind speed, and wind direction are important parameters in weather forecasting. At present, the measurement of wind speed and wind direction still uses traditional mechanical wind cup anemometers and wind vanes. It is not only easy to wear and short in service life, but also maintenance The cost is higher. [0003] At the same time, the existing weather test system is still composed of several independent instruments including temperature tester, humidity tester, atmospheric pressure tester, anemometer, and weather vane. Then, each instrument needs to be fixed and installed separately during installation, so it is not convenient to use and heavy workload. ...
