Below in conjunction with embodiment, describe the technical scheme of the contraposition speed measuring device of mine belt conveyor provided by the invention in detail.
Accompanying drawing explanation
Fig. 1 is the circuit block diagram of mine belt conveyor speed measuring device of the present invention;
Fig. 2 is the schematic circuit diagram of aerotron testing circuit;
Fig. 3 is the installation site schematic diagram of dry-reed tube on belt conveyer.
The specific embodiment
With reference to Fig. 1, the contraposition speed measuring device of mine belt conveyor provided by the invention, comprises belt conveying machine host, magnet, dry-reed tube, aerotron testing circuit, Liquid Crystal Display and annunciator.Wherein, belt conveying machine host is provided with micro controller system.
With reference to Fig. 3, magnet is arranged on the edge of each cylinder of belt conveyer, comprises the many places such as a, b, c.Each dry-reed tube coordinates with magnet on the some diverse locations that are arranged on belt conveyer.With reference to Fig. 2, dry-reed tube GH one end connects 12V power supply, the input end of other end access aerotron testing circuit.
Aerotron testing circuit is arranged on the master board of micro controller system.Aerotron testing circuit adopts the switching valve that model is 9013 to form, and in aerotron input circuit, series connection is connected to the T shape type filter network being comprised of resistance R 53 and resistance R 54 and electric capacity.At aerotron testing circuit, before and after dry-reed tube GH moves at every turn, a pair of high and low electric potential signal detected and form low frequency pulse signal output.
