Description
Technical field
The present invention relates to display screen demistings more particularly to a kind of display screen to heat demister and defogging method automatically, belongs to
In display screen corollary equipment and the technical field of method.
Background technology
Common display screen is antifog on the market or demisting is broadly divided into two kinds：One of which is to utilize fan and heater strip
It realizes to display screen surface blowing hot-air, passes through the mist of hot blast drying display screen surface or the steam of condensation.However practical application mistake
Cheng Zhong, display screen usually require that certain sealing performance, prevent foreign matter, sand and dust and steam from entering, and then damage internal circuit board
Or other assemblies.And the mode of this blowing heating causes display screen that must reserve air outlet, destroys leakproofness.
Another is before being affixed on display screen using ito film/glass, and the electrode of ito film/glass is directly connected with power supply,
The break-make of line is controlled by switch manual, carries out heating demisting.However in actual application, user can not know ITO
The dew-point temperature of glass front can not rationally determine the opportunity that heating is opened, and after often condensing on a display screen, just open
It heats or in the case where that can not possibly condense, manually opened heating causes electricity to waste.It is the present invention is directed to propose a kind of aobvious
Display screen automatic low-temp heats demister, improves the above problem.
Invention content
The present invention is to solve above-mentioned the deficiencies in the prior art, and traditional display screen demisting is manually mode, is carried
Demister and defogging method are heated automatically for a kind of display screen.
First purpose of the present invention is：A kind of display screen is provided and heats demister automatically, including：
Heating film, for carrying out heating demisting to display screen, the heating film is set on the panel of the display screen；
Heating film temperature sensor, for monitoring the heating film temperature, the heating film temperature sensor is set to heating film
Inside is simultaneously in contact with the heating film；
Temperature Humidity Sensor, for monitoring environment temperature and humidity, the Temperature Humidity Sensor is located at the effective of the display screen
In monitoring range；
Controller, for calculating demisting temperature, the controller is passed with the heating film, heating film temperature sensor and humiture
Sensor is mutually electrically connected.
Preferably, radius of the effective monitoring ranging from centered on display screen is the border circular areas within 50cm.
Second object of the present invention is：The defogging method that a kind of display screen heats demister automatically is provided, including
Following steps：
S1, data collection steps, controller acquire the data of heating film temperature sensor, Temperature Humidity Sensor；
S2, dew-point temperature calculate step, and the dew point in the currently active monitoring range is calculated according to the data of Temperature Humidity Sensor
Temperature；
S3, demisting temperature calculating step, it is permanent in dew-point temperature plus 1 ~ 2 DEG C obtains demisting temperature；
S4, heating film heating stepses, controller output order to heating film, heating film carry out demisting temperature adjusting.
The beneficial effects are mainly as follows：
1. innovatively propose the mode that demisting temperature is calculated according to dew-point temperature so that automation defrosting function obtains reality
It is existing.
2. being avoided that demisting energy consumption, the valuable energy has been saved.
3. it is simple for structure, defogging effect is notable, it is easy to spread and implement.
4. without manual operation, the safety of aviation operation is increased.
Description of the drawings
Fig. 1 is the structure diagram that a kind of display screen of the present invention heats demister automatically.
Specific embodiment
The present invention provides a kind of display screen and heats demister and defogging method automatically.Below in conjunction with attached drawing to skill of the present invention
Art scheme is described in detail, so that it is more readily understood and grasps.
A kind of display screen heats demister automatically, as shown in Figure 1, including heating film 1, heating film temperature sensor 2, temperature
Humidity sensor 3 and controller 4.
Wherein, for carrying out heating demisting to display screen, heating film 1 is set on the panel of display screen heating film 1；Heating
For film temperature sensor 2 for monitoring 1 temperature of heating film, heating film temperature sensor 2 is set to 1 inside of heating film and and heating film
1 is in contact；For Temperature Humidity Sensor 3 for monitoring environment temperature and humidity, Temperature Humidity Sensor 3 is located at the effective monitoring of display screen
In the range of；Controller 4 is used to calculate demisting temperature, controller 4 and heating film 1, heating film temperature sensor 2 and temperature and humidity sensing
3 phase of device is electrically connected.
Fog on display screen is caused by the temperature difference and humidity, and general demisting is carried out by heating display screen,
The effective temperature of heating is not studied, therefore can not also realize automation demisting.
This case is studied in demisting temperature, and heating temperature parameter can be obtained by calculating dew-point temperature, thus
Energy loss can be reduced while effective demisting, and automation demisting can be realized by controller.
Radius of the above-mentioned effective monitoring ranging from centered on display screen is the border circular areas within 50cm.Pass through the region
Delimitation so that the heating demister is also applicable to the demisting of outdoor environment.
To this case, a kind of display screen heats the defogging method of demister and carries out refinement description automatically, includes the following steps：
Data collection steps, controller acquire the data of heating film temperature sensor, Temperature Humidity Sensor.
Dew-point temperature calculates step, and the dew point in the currently active monitoring range is calculated according to the data of Temperature Humidity Sensor
Temperature；The calculating of dew-point temperature is theoretical subject, is currently to be disclosed by form, does not there is correlation computations formula, this
Case is by being implanted into dew-point temperature table data in controller, dew-point temperature being obtained by detection data comparison.
Demisting temperature calculating step, it is permanent in dew-point temperature plus 1 ~ 2 DEG C obtains demisting temperature；By research, demisting temperature
It is closely bound up with dew-point temperature, when demisting temperature is higher than 1 DEG C of dew-point temperature, you can realize effective demisting, and this case is for side
Just the scope control of heating film, demisting temperature range is between+2 DEG C of+1 DEG C ~ dew-point temperature of dew-point temperature.This section interior energy is effective
Demisting, and it is avoided that the energy excessively consumes.
Heating film heating stepses, controller output order to heating film, heating film carry out demisting temperature adjusting.Demisting temperature
Control is between+2 DEG C of+1 DEG C ~ dew-point temperature of dew-point temperature.
By above description it can be found that a kind of display screen of the present invention heats demister and defogging method automatically, innovate
Ground proposes the mode that demisting temperature is calculated according to dew-point temperature so that automation defrosting function is accomplished.It is avoided that and removes
Mist energy consumption has saved the valuable energy.It is simple for structure, defogging effect is notable, it is easy to spread and implement.Without grasping manually
Make, increase the safety of aviation operation.
Technical scheme of the present invention is fully described above, it should be noted that specific embodiment party of the invention
Formula is simultaneously not limited by the description set out above, the Spirit Essence of those of ordinary skill in the art according to the present invention structure, method or
All technical solutions that function etc. is formed using equivalents or equivalent transformation, all fall within protection scope of the present invention
