Problems solved by technology

However, the measurement of traditional wind speed is closely related to the location of the wind measurement, the direction of the wind dial, the moving speed of the surveyor, and manual observation. Therefore, this measurement is not real-time and cannot reflect the average wind speed of the entire roadway section. Complicated operation, low efficiency and low accuracy

Embodiment Construction

[0064] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0065] The invention solves the technical problem that single-point velocity measurement cannot reflect the average level of the entire air duct in the entire ventilation area, and can also be connected to a multi-parameter monitoring system for online real-time monitoring of wind speed, which can create huge economic and social benefits.

[0066] This embodiment provides a kind of coal mine roadway cross-section anemometer (see figure 1 — figure 2 ), including a host frame and a pair of probes 4, the host frame and the probes 4 are connected by signal lines, and the signal lines are fixed by cab...

Abstract

The invention belongs to the technical field of coal mine roadway ventilation, and particularly relates to a coal mine roadway section anemometer and a measurement method thereof. The average wind velocity, not the single point wind velocity, of the whole section of the coal mine roadway can be accurately measured online in real time. According to the technical scheme, the coal mine roadway section anemometer comprises a host frame and two probes. The probes are connected with the host frame through signal lines. The host frame comprises an upper cover and a lower shell. The upper cover is connected on the lower shell. The upper cover is provided with a liquid crystal display screen. The host frame is internally provided with a signal processing board, a circuit fixing board and a displaycommunication board. The circuit fixing board is fixed on the lower shell. The signal processing board is connected with the circuit fixing board. The display communication board is connected with theliquid crystal display screen and used for data display. The probes are the ultrasonic transducers and connected with the signal processing board through the signal lines, the signal processing boardis connected with the display communication board and the specific measurement method is applied to perform measurement.

Description

technical field [0001] The patent of the invention belongs to the technical field of coal mine roadway ventilation, and specifically relates to a coal mine roadway section anemometer and a measuring method thereof. Background technique [0002] Wind speed measurement in coal mine roadway has always been an important problem that plagues coal mine safety production. Wind speed detection is an important part of coal mine ventilation management. The wind speed during coal mining directly affects the life safety of miners. If the wind speed is too small, the harmful gas will not be diluted in time, which may cause an explosion; if the wind speed is too high, it may cause a dust explosion. [0003] At present, the wind speed measuring instruments used to measure wind speed in coal mines mainly include mechanical anemometer, mechanical and electronic anemometer, electronic impeller type, ultrasonic type and so on. In order to ensure the safe production of mines, mine wind speed ...
