S33, communication module is contrasted standard electric signal with setting value, and is sent out according to comparing result to controller
OFF signal.
Further, each deicing subsystem of artificial selection is also needed to before step S1 as automatic de-icing pattern or manual
Deice mode, the master switch of deicing system control all automatic de-icing patterns of each deicing subsystem or all hands simultaneously
Dynamic deice mode, when selecting automatic de-icing pattern, deicing is carried out according to above-mentioned steps, when selecting manual deice mode, department
Machine can open or simultaneously close off simultaneously all near infrared light emitters.
In use, often saving multiple icings are mounted on the key position (such as brake lever) of the brake rigging in compartment
Detector 2, complete detection often save the icing information in compartment, and after ice and snow layer thickness exceedes setting value, icing detector 2 is to control
Device 3 sends signal, and controller 3 carries out logical operation to input signal, (need to consider that multiple freeze passes when meeting deicing unlocking condition
The icing thickness information that sensor 201 detects) backward near infrared light emitter 1 sends open signal, and launch near infrared light
Device 1 opens deicing；After ice and snow layer comes off, icing detector 2 sends signal to controller 3 again, and controller 3 is believed input again
Number carry out logical operation, send shutdown signal near infrared light emitter 1 after deicing closedown condition is met, make near infrared light
Emitter 1 is closed, so as to realize intelligent automatic deicing.
In summary, the embodiment of the present invention provides a kind of rail vehicle deicing subsystem based near infrared light coating, bag

After the icing detector of key position detects that the ice and snow layer thickness adhered at this exceedes setting value, just letter is sent to controller
Number.Controller carries out logical operation to the input signal of several icing detectors, to installation after deicing unlocking condition is met
Near infrared light emitter above brake rigging sends open signal, opens near infrared light emitter.It is near red
Outer light is irradiated near infrared light coating surface through ice and snow layer makes its rapid heat, and the ice and snow layer bottom that coating surface is adhered to is fast
Speed is melted, so that ice and snow layer is easy to come off removal from coating surface under the effect such as Vehicular vibration and extraneous wind-force.This is removed
Ice subsystem is on the often section compartment of rail vehicle, with collectively forming deicing system, master switch located at the master switch of operating room
The deicing subsystem for often saving compartment can be controlled to carry out above-mentioned automatic de-icing process, or directly often saved by being manually opened and closed on compartment
Near infrared light emitter carries out deicing.The deicing system of the embodiment of the present invention has two kinds of moulds of automatic de-icing and manual deicing
Formula, automatic de-icing pattern is in most cases selected, its automaticity is higher, is participated in without artificial, when automatic de-icing pattern
Manual deice mode can also be selected during failure, avoid because the damage of automatic de-icing pattern and caused by non-deicing show
As occurring.With except speed of icing is fast, efficiency high and energy consumption are low the advantages of.The present invention, which has, removes fast speed of icing, efficiency high and energy consumption
The advantages of low.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
The present invention is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：It still may be used
To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic；
And these modification or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and
Scope.
