Abstract:
In order to make up for the shortcomings of the traditional gas flow measurement device, and to realize more accurate dynamic and continuous monitoring of gas drainage, a new type of ultrasonic gas flow meter based on MS1030 is developed according to the characteristics of coal mine working conditions and the flow measurement principle of time difference method. A hardware system of ultrasonic gas flow is designed, which is based on domestic high-speed measuring chip MS1030, STM32F100 as the main control chip, and equipped with modules such as drive circuit and signal conditioning circuit. The system control software is developed, the development of the test prototype is completed, and the prototype is verified by the standard equipment. The verification results show that the ultrasonic gas flowmeter has the characteristics of high accuracy and good repeatability, which provides a powerful flow monitoring equipment for the underground gas drainage monitoring system.
