Description
Technical field
The invention belongs to aircraft deicing field, and in particular to a kind of icing heater function detecting method.
Background technology
What the electric current when size of heater heating power is typically with its work reflected.Detection to operating current is general
It is that current sensor is concatenated in heater circuit, the current signal or voltage signal of current sensor output are again through follow-up signal tune
Sent after reason processing of circuit to CPU and resolved and judged, the program adds the complexity of system hardware, while reduces system
Reliability.
In the icing detection system of resonant mode, icing detection control box is in order to realize icing alarm function, it is necessary to detects
The frequency signal of icing detector output.The frequency signal of icing detector output exists certain with the heating properties of its heater
Association, i.e., when heater works normally before the deadline, it should can be by the ice sheet on icing detector sensing probe
Remove completely, at this time, the frequency signal of icing detector output should recover to original frequency.
The content of the invention
Goal of the invention：Under the premise of any hardware is not increased, by being detected to the frequency signal of icing detector,
Realization is connect to be detected the heating function of icing heater.
Technical solution：A kind of icing heater function detecting method, for the icing detection system of resonant mode, icing detection
System includes the icing detector of front end and the icing detection control box of rear end, when icing detection control box sends heating deicing letter
After number, in heating time as defined in arrival, whether the signal frequency for judging icing detector is the initial value not frozen, if being equal to
Initial value, then icing heater is normal, otherwise dysfunction.
When frequency variation reaches certain value, the spy control box that freezes then exports icing alarm signal, while starts deicing.
Icing detection control box produces electromagnetic viscosimeter to icing detector offer ± 15VDC power supplys by icing detector, and
Output frequency signal.
When being deposited on the sensing probe of icing detector without ice, it exports a fixed frequency signal, with ice sheet
Continuous accumulation on sensing probe, its frequency signal exported then accordingly change.
Heating time as defined in described is 12s.
Beneficial effect：It is any need not additionally increase on the basis of icing detection point system is in order to realize icing detection function
Under the premise of hardware, the frequency signal of icing detector need to be only detected, you can realize the inspection of heater heating properties indirectly
Survey, reduce the complexity of icing detection system hardware, meanwhile, improve the reliability of icing detection system.
Brief description of the drawings
Fig. 1 is the schematic diagram of deicing system of the present invention.
Embodiment
With reference to Fig. 1, the icing detection system of resonant mode includes the icing detector of front end and the icing detection control of rear end
Box.Wherein icing detector sends the resonance signal of corresponding frequencies according to ice layer thickness, is received by the icing detection control box,
And heating deicing signal is sent in due course.According to icing detection system using when environmental condition and satisfaction icing detection is repeated
Needs, the heating power size for determining icing detector is 30W, with ensure the heater of icing detector start heat after
The ice sheet on icing detector sensing probe should be removed completely within 10 seconds.Meanwhile realized such as in icing detection control box
Lower function：When thering is ice gradually to accumulate on icing detector sensing probe, its output frequency correspondingly by original frequency it is gradual under
Drop, when the CPU determination frequency slippages in icing detection control box reach certain value △ f, CPU output heating instructions start knot
The heater of ice sounder carries out heating deicing, 10 seconds and then the secondary recovery feelings for passing through software detection frequency signal by CPU
Condition, when frequency retrieval has arrived initial value, illustrates that the heating function of icing heater is normal, is otherwise exception.
For the present invention under the premise of it need not additionally increase any hardware of icing detection system, improve icing detection system can
By property.Verify, work well by icing mnncl tcst and flight test.
