Description

Wind speed sensor for coal mine
Technical field
The utility model relates to a kind of sensor, particularly a kind of wind speed sensor for coal mine.
Background technology
Along with continuous expansion and the extension of mine underground mining scope, subsurface environment also becomes and becomes increasingly complex, and to subsurface environment, especially the requirement of air is more and more higher.Ventilation is carried out in the down-hole, and is pure and fresh to guarantee underground air, satisfies staff's eupnea and the gathering of minimizing harmful gas and also becomes more and more important.
At present the problem that occurs is: because real-time monitoring is not very desirable to ventilation condition under the mine, harmful gases such as gas and the carbon monoxide situation of assembling can not in time be understood, cause the underground work personnel to suffocate easily and cause mine disaster.
Summary of the invention
The utility model provides a kind of wind speed sensor for coal mine in order to solve the problem that prior art exists.
Wind speed sensor for coal mine of the present utility model, the carrying handle hand that comprises housing, is positioned at the display on the described housing and is connected with described housing, it is characterized in that: also be provided with ultrasonic transducer and single chip circuit plate in the described housing, described housing also is connected with eddy current generation body; Wherein, ultrasonic transducer is made up of ultrasonic transmit circuit and ultrasound wave receiving circuit; Single-chip microcomputer is EEPROM.Described eddy current generation body and described housing junction are provided with eddy current generation body sealing gasket.
Wind speed sensor for coal mine of the present utility model adopts eddy current generation body, ultrasonic transducer and single chip circuit plate; Utilization is passed the ultrasound wave of air and is modulated by vortex, detects vortex frequency and measure wind speed from modulated wave.In the ultrasonic transducer, ultrasonic transmit circuit emission constant amplitude ultrasound wave, ultrasound wave receiving circuit receive the sound wave of having been modulated by vortex.When absence of vortices, the ultrasound wave receiving circuit receives continuous wave signal; When vortex is arranged, because rotatablely moving of vortex pressure inside gradient and vortex caused hyperacoustic refraction, reflection and absorption effect, the signal amplitude that receives is reduced.Vortex is by behind the acoustic beam, and the signal that receives returns to normal again.Therefore, the amplitude of ultrasonic change frequency is consistent with the frequency of vortex, and single-chip microcomputer detects ultrasonic beam changes in amplitude number of times from the ultrasound wave receiving circuit can record air speed value.
Wind speed sensor for coal mine of the present utility model is carried out continuous monitoring by the measuring wind speed to mine laneway, can grasp the ventilation condition of mine laneway by display, guarantee normal work production security, also have simultaneously measure accurately, monitoring in real time, advantage such as easy to use, powerful.This shows that the utility model relatively has outstanding substantive distinguishing features with prior art and improves significantly.
Description of drawings
Fig. 1 is the structural representation of wind speed sensor for coal mine of the present utility model.
Embodiment
By accompanying drawing 1 as can be known: wind speed sensor for coal mine of the present utility model, the carrying handle hand 1 that comprises housing 4, is positioned at the display 3 on the described housing 4 and is connected with described housing 4,4 also are provided with ultrasonic transducer 7 and single chip circuit plate 2 in the described housing, and described housing 4 also is connected with eddy current generation body 6; Wherein, ultrasonic transducer 7 is made up of ultrasonic transmit circuit and ultrasound wave receiving circuit; Single-chip microcomputer is EEPROM.Described eddy current generation body 6 is provided with eddy current generation body sealing gasket 5 with described housing 4 junctions.
Wind speed sensor for coal mine of the present utility model adopts eddy current generation body 6, ultrasonic transducer 7 and single chip circuit plate 2; Utilization is passed the ultrasound wave of air and is modulated by vortex, detects vortex frequency and measure wind speed from modulated wave.In the ultrasonic transducer, ultrasonic transmit circuit emission constant amplitude ultrasound wave, ultrasound wave receiving circuit receive the sound wave of having been modulated by vortex.When absence of vortices, the ultrasound wave receiving circuit receives continuous wave signal; When vortex is arranged, because rotatablely moving of vortex pressure inside gradient and vortex caused hyperacoustic refraction, reflection and absorption effect, the signal amplitude that receives is reduced.Vortex is by behind the acoustic beam, and the signal that receives returns to normal again.Therefore, the amplitude of ultrasonic change frequency is consistent with the frequency of vortex, and single-chip microcomputer detects ultrasonic beam changes in amplitude number of times from the ultrasound wave receiving circuit can record air speed value.
Wind speed sensor for coal mine of the present utility model is mainly used in the detection that various tunnels under the coal mine, air port, ventilating fan well head etc. are located wind speed, to guarantee the safety in production in colliery.Wind speed sensor for coal mine of the present utility model is essential safe type, is a kind of intelligent measuring instrument, and environmental suitability is strong, and Installation and Debugging are convenient, after national explosion-proof test office carries out on-line test, can with the supporting use of domestic all kinds of Coalmine's Monitoring and Controlling System.
