Brief description
Fig. 1 is the structural representation of this utility model specific embodiment.
Specific embodiment
In conjunction with the drawings and specific embodiments, this utility model is further illustrated.
As shown in figure 1, a kind of infrared detecting device, including control module 2 and detection module 1, in this specific embodiment, control
Molding block 2 includes power supply and single-chip microcomputer（In figure is not shown）, power supply powers for single-chip microcomputer, power supply can be provided by battery or by
Adapter connects civil power and provides.Described detection module 1 includes infrared transmission module 11, infrared receiving module 12 and a cavity volume 13, this
In specific embodiment, infrared transmission module 11 is made up of infrarede emitting diode, and infrared receiving module 12 is by phototriode structure
Become, certainly, in other embodiments, infrared receiving module 12 can also be made up of infrared receiving diode, cavity volume 13 is by one or two
The transparent tube of end opening（As glass tubing）There is provided, the opening at described transparent tube 13 two ends is respectively inlet 131 and liquid outlet
132, certainly, in other embodiments, cavity volume 13 can also be can to allow, by other, the material that Infrared passes through, and moulds Ru transparent
Material etc. encloses, and shape can be cylinder, cuboid etc..
The collector of the positive and negative terminal of infrarede emitting diode 11 and phototriode 12 and emitter-base bandgap grading respectively with control module 2
Single-chip microcomputer connects, in the present embodiment, infrarede emitting diode 11 negative terminal and the emitter-base bandgap grading of phototriode 12 be simultaneously connected to
The earth terminal of the single-chip microcomputer of control module 2, glass tubing 13 is arranged between infrarede emitting diode 11 and phototriode 12, glass
Inlet 131 and the pipeline connection to be measured of glass pipe 13, when glass tubing 13 no liquid, it is infrared that infrarede emitting diode 11 sends
Light passes through glass tubing 13 to reach primary importance, when glass tubing 13 has liquid, the infrared light that infrarede emitting diode 11 sends
Line passes through glass tubing 13 and liquid to reach the second position, and phototriode 12 is arranged on primary importance and is used for receiving Infrared,
Certainly, in other embodiments, phototriode 12 can arrange the second position for Infrared.
During detection, the single-chip microcomputer output drive signal of control module 2 drives infrarede emitting diode 11 to send Infrared,
When in pipeline to be measured anhydrous when（Certainly, in other embodiments or other liquid）, also anhydrous in glass tubing 13, red
UV light passes through glass tubing 13 to reach phototriode 12, and phototriode 12 turns on after receiving Infrared, control module 2
Single-chip microcomputer receive low level signal, when having water in pipeline to be measured, in glass tubing 13, be also filled with water, Infrared pass through glass
After glass pipe 13 and water, due to the refraction of water, Infrared cannot reach phototriode 12, and phototriode 12 is not received by
End after Infrared, the single-chip microcomputer of control module 2 receives high level signal, then can be known by receiving the change of signal
Do not go out to have water or anhydrous.Achieve indirect detection, safety, without isolation, simplifies the design of circuit it is desirable to space is less, detection
Speed is high, realizes being more prone to, cost is relatively low.
The detection process that phototriode 12 arranges the second position is similar to recited above, and this no longer describes in detail.
