Shield outer temperature sensor 21 after work to be stopped.
Contribution of the present utility model is the provision of a kind of LED display double temperature control system, the system using air-conditioning and
The dual intelligent temperature control system that axial flow blower is combined.Air-conditioning has refrigeration and dehumidification function in itself, can be inside LED screen body
Temperature and humidity is controlled in rational scope.Under the hot environment in summer, when LED display just works, air-conditioning is often needed
It can be only achieved cooling-down effect the long period, now by shielding temperature outside outer temperature sensor receiving screen, and signal be fed back to
First comparator, judges that the temperature value of temperature sensor, can be in LED compared with shielding the temperature value of outer temperature sensor in screen
Display screen starting up is reached to air-conditioning before preferable refrigeration, while starting air-conditioning and axial flow blower, axial flow blower is played
Quick heat exchange action, by shielding the exchange of inside and outside air, reduces the time that LED display works at high temperature.Work as air-conditioning
Itself can be in control flow during temperature, and temperature detect switch (TDS) can carry out power down process in good time, close axial flow blower, it is to avoid axial flow blower draws
Enter cold air in external environment hot-air and discharge screen, cause air-conditioning uninterruptedly to freeze, increase unnecessary power consumption, so as to reach
To energy-saving effect.In the case where winter or outdoor temperature are relatively low, now by shielding temperature outside outer temperature sensor receiving screen,
And signal is fed back into first comparator, temperature and signal is fed back into the second comparator in temperature sensor receiving screen in screen,
The temperature value of temperature sensor is compared with shielding the temperature value of outer temperature sensor in screen, if shielding inner and outer ambient temperature differences phase
If near, then temperature detect switch (TDS) will not open axial flow blower without authorization.Only air-conditioning screen in heat reach on set temperature value when,
Air-conditioning can just carry out temperature control processing.
【Brief description of the drawings】
Fig. 1 is structural representation of the present utility model.
【Embodiment】
The following example is explained further and supplemented to of the present utility model, does not constitute any limit to the utility model
System.
Embodiment 1
As shown in figure 1, a kind of LED display double temperature control system of the present embodiment, including for exchanging air in screen
The air-conditioning 60 of temperature in axial flow blower 50 and regulation screen, described axial flow blower 50 and air-conditioning 60 are connected with controller 40, institute
The controller 40 stated connects the second comparator 30, described the second comparator 30 connection LED screen power supply 10, described controller 40
The open and close of axial flow blower 50 and air-conditioning 60 are controlled according to the feedback signal of the second comparator 30.Traditional LED display
Temperature control processing is handled using single air-conditioning or axial flow blower substantially, simple to carry out temperature adjusting using axial flow blower,
The simple heat exchange action look to inside and outside screen of radiating, and with that air humidity can be caused larger after external environment heat exchange in screen, shadow
Ring the service life and security performance of LED display；It is simple to carry out temperature adjusting using air-conditioning, under power consumption, and hot weather
Cooling needs to increase power or During Initial Stage Construction increases air-conditioning quantity.And in the present embodiment, under the hot environment in summer, LED
When display screen just works, air-conditioning generally requires the long period and can be only achieved cooling-down effect, the controllable shaft flow fan 50 of controller 40
Operated simultaneously with air-conditioning 60, axial flow blower 50 plays quick heat exchange action, by shielding the exchange of inside and outside air, reduce LED
The time that display screen works at high temperature, while also reducing the power consumption of air-conditioning 60.When air-conditioning 60 itself being capable of temperature in control flow
When, controller 40 will control axial flow blower 50 to close, it is to avoid axial flow blower 50 introduces cold in external environment hot-air and discharge screen
Air, causes the uninterruptedly refrigeration of air-conditioning 60, increases unnecessary power consumption, so as to reach energy-saving effect.
Embodiment 2
As shown in figure 1, the present embodiment on the basis of embodiment 1 the specific perfect control axial flow blower 50 of controller 40 with
The mode of air-conditioning 60.The described internal memory of the second comparator 30 contains temperature upper limit and the interior temperature upper limit value of screen, the second ratio in screen
Compared with temperature sensor 31 in the connection screen of device 30, temperature signal gives the second comparator 30 in the feedback screen of temperature sensor 31 in screen.Institute
First comparator 20 is additionally provided between the second comparator 30 and LED screen power supply 10 stated, described first comparator 20 is connected
The outer temperature sensor 21 of screen, the outer temperature signal of the outer feedback of temperature sensor 21 screen of described screen is to first comparator 20.Described
The outer temperature sensor 21 of screen is worked when LED screen power supply 10 is opened, and outer temperature sensor 21 is shielded after LED display normal work and is stopped
Only work.In the present embodiment, LED screen power supply 10 is opened, LED display work, if being at this moment in summer, shields outer temperature height,
In LED screen electric power starting, shield outside screen of the temperature signal higher than the interior setting of first comparator 20 that outer temperature sensor 21 feeds back
Temperature upper limit, and the temperature signal that temperature sensor 31 feeds back in shielding is also above temperature upper limit in screen, at this moment controller 40
Just control axial flow blower 50 is opened simultaneously with air-conditioning 60, reaches the effect for exchanging temperature in screen inner air and outer air and reduction screen；Work as screen
The temperature signal that outer temperature sensor 21 feeds back is higher than the outer temperature upper limit of the screen set in first comparator 20, and shields interior temperature
The temperature signal that sensor 31 feeds back is opened less than temperature upper limit in screen, at this moment 40 control air-conditionings 60 of controller, is made in screen
Temperature stabilization, not higher than shields interior temperature upper limit, is also not less than temperature upper limit value in screen.If outdoor temperature is low, shield outer temperature
The temperature that sensor 21 is received is less than the outer temperature upper limit value of screen, and the temperature that temperature sensor 31 is received in shielding is also below screen
During interior temperature upper limit value, the control air-conditioning 60 of controller 40 is stopped simultaneously with axial flow blower 50, because LED display is in work
During can produce heat, shield outer temperature sensor 21 and be stopped, temperature sensor 31 works always in screen, when the interior temperature of screen
Higher than during temperature upper limit, the control air-conditioning 60 of controller 40 is opened in screen, make in screen limit temperature in screen temperature upper limit with
In screen between temperature upper limit value.
Although being disclosed by above example to the utility model, protection domain of the present utility model not office
It is limited to this, under conditions of conceiving without departing from the utility model, deformation, replacement that each component is done to more than etc. will fall into this
In the right of utility model.
