Title:
ULTRASONIC AIR VELOCITY SENSOR FOR UNDERGROUND COAL MINE
Document Type and Number:
WIPO Patent Application WO/2021/093378
Kind Code:
A1
Abstract:
An ultrasonic air velocity sensor for an underground coal mine, comprising a base (1). The base (1) is hung and connected to a tunnel roof. A three-dimensional gyro sensor (3) is mounted in the center of the upper horizontal plane of the base (1). A first transmitting terminal (4), a second transmitting terminal (5), a first receiving terminal (6) and a second receiving terminal (7) are mounted on the lower horizontal plane of the base (1). The sensor also comprises a temperature sensor (9), a humidity sensor (10), and an air pressure sensor (11). The temperature sensor (9), the humidity sensor (10) and the air pressure sensor (11) are embedded into the lower horizontal plane of the base (1) and are located in a ring formed by the transmitting terminals and the receiving terminals. According to the present invention, measurement data can be corrected due to interference caused by environmental factors and own factors of the sensor, and the accuracy of the measurement data is improved.
