Embodiment Construction

[0031] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0032] Such as figure 1 As shown in , an ultrasonic anemometer includes a power supply module, a main control module, an ultrasonic wind measurement module, a data communication module, a data storage module, a temperature compensation module and a gyroscope balance device. Among them, the ultrasonic wind measurement module realizes the function of ultrasonic measurement of wind speed and direction, and the gyroscope balance device realizes the self-balancing function of the wind measuring instrument.

[0033] The main control chip in the main control module cooperates with the timer to generate a pulse signal with a frequency of 200kHz and a duty cycle of 50%. The pulse signal is time-divisionally multiplexed into four pulse signals through a 4-to-1 analog switch, and is amplified by the transmission drive circuit. After driving the ultrason...

Abstract

The invention discloses a gyroscope balance device for an ultrasonic anemorumbometer and an angle self-adaptive balance adjustment method of the gyroscope balance device, wherein the ultrasonic anemorumbometer comprises a power supply module, a main control module, an ultrasonic wind measurement module, a data communication module, a data storage module, a temperature compensation module and a gyroscope balance device. The gyroscope balance device comprises a gyroscope sensor and a universal joint, wherein the gyroscope sensor is used for monitoring the working angle of the ultrasonic anemorumbometer in real time, wherein attitude calculation is carried out on the working angle of the anemorumbometer through a PID algorithm, and the universal joint is rotated to perform angle adjustment according to the change of the working angle of the anemorumbometer, and finally the ultrasonic anemorumbometer can achieve self-balancing in a short time.

Description

technical field [0001] The invention relates to a balance device, in particular to a gyroscope balance device for an ultrasonic anemometer and an angle self-adaptive balance adjustment method thereof. Background technique [0002] In recent years, with the development of electronic hardware technology and the improvement of CPU computing speed, ultrasonic wind measurement technology has also developed rapidly. Compared with traditional mechanical wind cups, wind vanes and other wind measurement devices, ultrasonic wind measurement technology is measuring Accuracy, real-time, stability and other aspects have significant advantages. [0003] Under the background of vigorously promoting the marine development strategy of the country, as my country strengthens the monitoring of marine meteorology, the requirements for marine meteorological monitoring are also increasing. Maritime meteorological observation mainly takes the form of islands, sea buoys, and meteorological observat...
