According to the energy-saving LED dot-matrix image-text display, the purpose of reducing energy consumption is realized through controlling rotary speed of the fan set.
Description
Technical field
The utility model relates to a kind of display screen, is specifically related to a kind of energy-saving LED dot matrix graphic display screen.
Background technology
LED dot matrix graphic display screen by several ten thousand so that a hundreds of thousands semiconductor light-emitting-diode (be called for short LED) pixel form by dot matrix is evenly distributed, the well-known LED light efficiency of lighting a lamp is low, most of electric energy sheds with the form of heat, for guaranteeing display screen, the display screen heat radiation that forms to by numerous LED, being lit a lamp works normally, usually dispel the heat to display screen with blower fan, present blower fan working method is that display screen switch opens rear fan just starts heat radiation immediately, the rotating speed of blower fan does not possess the ability of any power transfer, namely how many interior temperature of tube display screen is not, all normal full load runnings of blower fan, and the junction temperature of also lighting a lamp less than LED far away of the temperature in display screen in some cases, blower fan there is no need running at full capacity, even ambient temperature is on the low side winter, display screen fully can be by shell and the extraneous direct heat exchange purpose that reaches heat radiation of self.The purpose that we install blower fan is for the heat radiation of the display screen in work, even all need not open blower fan in the situation that temperature also there is no need running at full capacity over the junction temperature blower fan fully, in order to avoid cause the waste of electric energy.
Summary of the invention
In order to solve the deficiency in background technology, the purpose of this utility model is to overcome the defect of background technology, provides a kind of energy consumption lower LED dot matrix graphic display screen.
For achieving the above object, the technical solution adopted in the utility model is: a kind of energy-saving LED dot matrix graphic display screen, comprise LED dot matrix picture and text display module, drive the control system of controlling the work of described LED dot matrix picture and text display module and the blower fan group of to described display screen, dispelling the heat, it is characterized in that: it also comprises the temperature monitor that is arranged in described display screen, described temperature monitor is connected with described control system, and described control system also is connected with described blower fan group by frequency converter.
In preferred embodiment of the utility model, comprise that further described display screen also comprises character base module and the figure library module that is connected with described control system.
In preferred embodiment of the utility model, comprise that further described LED dot matrix picture and text display module is a plurality of LED lamps by 5*7,5*8, the 8*8 dot matrix display screen that combines by dot matrix of a kind of array mode wherein.
In preferred embodiment of the utility model, comprise that further described display screen also comprises the wireless communication module that the mode by wireless transmission is connected with described control system.
In preferred embodiment of the utility model, further comprise described wireless transmission method be GPRS, 3G, bluetooth or infrared ray one of them.
In preferred embodiment of the utility model, comprise that further described display screen also comprises the alarm module that is connected with described control system.
Usefulness of the present utility model is: a kind of energy-saving LED dot matrix graphic display screen of the present utility model also comprises the temperature monitor that is arranged in display screen, and temperature monitor is connected with control system, control system is connected with the blower fan group by frequency converter, during use, control system can start frequency converter and control unit according to the temperature detection data of temperature monitor feedback, thereby blower fan is moved under more suitable power, reduce unnecessary power consumption, so the utility model energy consumption is lower.
Figure of description
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of preferred embodiment of the present utility model.
In figure: 2, LED dot matrix picture and text display module, 4, control system, 6, the blower fan group, 8, temperature monitor, 10, frequency converter, 12, character base module, 14, the figure library module, 16, wireless communication module, 18, alarm module.
Embodiment
In order to make those skilled in the art person understand better the utility model scheme, and above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with embodiment and embodiment accompanying drawing, the utility model is described in further detail.
as shown in Figure 1, a kind of energy-saving LED dot matrix graphic display screen, comprise LED dot matrix picture and text display module 2, drive the control system 4 of controlling 2 work of LED dot matrix picture and text display module and the blower fan group 6 of to display screen, dispelling the heat, wherein LED dot matrix picture and text display module 2 is to press 5*7 by a plurality of LED lamps, 5*8, 8*8 is the dot matrix display screen that combines by dot matrix of a kind of array mode wherein, can more comprehensively show the Chinese and western languages word, the information such as picture, also comprise the temperature monitor 8 that is arranged in display screen, wherein temperature monitor 8 is connected with control system 4, control system 4 also is connected with blower fan group 6 by frequency converter 10.During use, control system 4 can detect and whether the temperature detection Data Control fed back opens blower fan group 6 according to temperature monitor 8, also can control and start frequency converter 10 according to the temperature detection data, control the rotation speed of fan of unit 6, thereby blower fan group 6 is optionally moved, or moved under more suitable power, can set in advance two node temperatures in control system 4, one is the node temperature of opening blower fan group 6, and one is the node temperature of opening frequency converter 10.Therefore the utility model can reduce unnecessary power consumption, and energy consumption is lower.
