The communication unit comprises a communication module. The controller, the communication unit, the memory, and the power supply are disposed in an electric cabinet in a closed manner. The sensor unit is disposed on the outer side of the electric cabinet. The mine pipeline wind speed measurement device has advantages of simple structure, small wear, high measurement accuracy, and wide application range.
Description
Technical field
The utility model relates to the measurement mechanism in mine ventilation field, especially relates to a kind of mine air velocity duct measurement mechanism.
Background technology
In mine ventilation and various ventilating engineering, conventionally want gas wind speed in measuring channel, conventional metering system is mechanical type wind table, photo-electric probe and thermocouple probe etc., mechanical type wind table, photo-electric probe all adopt impeller rotation in measuring unit's time to carry out measuring wind, measuring accuracy is lower, and mechanical wear is large; Thermocouple probe cannot be used for the explosion-proof places such as mine.
Utility model content
Technical problem to be solved in the utility model is, overcomes the above-mentioned deficiency of prior art, provides a kind of measuring accuracy high, and mechanical wear is little, mine air velocity duct measurement mechanism applied widely.
The utility model solves the technical scheme that its technical matters adopts:
A kind of mine air velocity duct measurement mechanism, the sensor unit, man-machine interaction unit, communication unit, storer and the power supply that comprise controller and be connected respectively with described controller, described sensor unit comprises dynamic pressure transmitter and gas density transmitter, described man-machine interaction unit comprises display and button, and described communication unit comprises communication module; Described controller, communication unit, storer and power supply are enclosed in electric cabinet, and described sensor unit is installed on electric cabinet outside.
Further, described controller, by communication module access network, is connected to monitor terminal.
Further, described communication module is the Internet communication module or cordless communication network module.
Further, described sensor unit is connected with described controller by signal processing unit.
Further, described controller is embedded chip.
Further, described dynamic pressure transmitter is explosion-proof type dynamic pressure transmitter, and described gas density transmitter is anti-explosion type gas density transmitter.
Further, described power supply is explosion-proof electrical source.
Further, described electric cabinet is with explosion-resistant enclosure.
Because dynamic pressure transmitter of the present utility model is selected explosion-proof type dynamic pressure transmitter, gas density transmitter is anti-explosion type gas density transmitter, shell protection grade is high, has overcome mechanical type, photo-electric air speed measuring apparatus and has existed the large and thermojunction type measuring instrument of wearing and tearing can not be used for the restriction in coal mine inferior explosion-proof place.
The ventilation parameters such as dynamic pressure transmitter and gas density transmitter can Measurement accuracy wind speed, density, dynamic pressure, applicable to various pipe ventilated parameter measurements.
brief description of the drawings:
Fig. 1 is the structured flowchart of the utility model embodiment.
embodiment:
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to accompanying drawing, sensor unit 2, man-machine interaction unit 3, communication unit 4, storer 5 and power supply 6 that the present embodiment comprises controller 1 and is connected respectively with described controller 1, described sensor unit 2 comprises dynamic pressure transmitter 21 and gas density transmitter 22, described man-machine interaction unit 3 comprises display 31 and button 32, and described communication unit 4 comprises communication module 41; Described controller 1, communication unit 4, storer 5 and power supply 6 are enclosed in electric cabinet, and described sensor unit 2 is installed on electric cabinet outside.Sensor unit 2 is for measuring the ventilation index of mine pipeline, by signal processing unit 7, sensor signal is amplified and A/D conversion, input control device 1 carries out signal processing, and controller 1 is sent to monitor terminal 8 by the sensor information value of acquisition by communication unit 4.
Dynamic pressure transmitter 21 and gas density transmitter 22 are for measuring the ventilation index of mine pipeline, dynamic pressure transmitter 21 is for measuring the distinguished and admirable dynamic pressure in mine pipeline, the automatic tracking direction of dynamic pressure transmitter 21, obtain rapidly wind speed and dynamic pressure information according to the corresponding relation of gas differential pressure and wind speed, judge whether to add forced ventilation according to the dynamic pressure information of real-time acquisition; Gas density transmitter 22 is for measuring the atmospheric density in mine pipeline, be less than formulation standard if record atmospheric density, need take a breath to mine pipeline, meet the needs of operating personnel to oxygen, water down down-hole toxic and harmful and dust, ensure safety in production; The value of information that sensor obtains is controlled communication module 41 by controller 1 and is sent real-time metrical information to monitor terminal 8, simultaneously the operating personnel of monitor terminal 8 also can long-range transmission control command, even if people is not at the scene like this, also can have a clear understanding of the specific environment situation of mine, be convenient to safeguard and control, and ensured personal safety; Button 32 is for arranging various operational factors; Display 31, for showing concrete configuration information, is convenient to man-machine interaction; Storer 5 is for the monitoring information of storage sensors; Power supply 6 is for powering to controller 1.
The communication module 41 of the present embodiment is the Internet communication module or cordless communication network module, or the combination of the two, and controller 1, by communication module 41 access networks, is connected to monitor terminal 8, and operating personnel can pass through the long-range transmission control command in internet.
The controller 1 of the present embodiment is embedded chip.
Because mine is explosive place, the dynamic pressure transmitter 21 of the present embodiment is explosion-proof type dynamic pressure transmitter, gas density transmitter 22 is anti-explosion type gas density transmitter, shell protection grade is high, has overcome mechanical type, photo-electric air speed measuring apparatus and has existed the large and thermojunction type measuring instrument of wearing and tearing can not be used for the restriction in coal mine inferior explosion-proof place; Power supply 6 is explosion-proof electrical source; Electric cabinet is with explosion-resistant enclosure.
