But the LED display unit of SC sigmal control

Technical field

The utility model relates to the radiation fan art, but refers in particular to a kind of LED display unit that is applicable to the SC sigmal control of radiation fan.

Background technique

At present, be used in the radiation fan of equipment such as computer, power supply unit on the market, normally constitute by fan seat and flabellum, flabellum rotates during use, accelerate air flows, reach thermolysis, many producers on radiation fan, increase have can be luminous the LED lamp, obtain a kind of radiation fan that produces the rotation light with this, only play simple decorating action yet its deficiency is luminous LED lamp.Situation demonstration to rotating speed or temperature needs special device more, and can't show intuitively by the flicker of LED lamp.

The model utility content

The utility model is at the defective of prior art existence, but main purpose provides a kind of LED display unit that is applicable to the SC sigmal control of radiation fan.It can show the rotating speed of fan or the temperature regime flicker pattern by corresponding LED lamp intuitively.

For achieving the above object, the utility model adopts following technological scheme:

But a kind of LED display unit of SC sigmal control, comprise a collecting unit, a led display unit, a microcontroller and a power circuit, wherein, this microcontroller is electrically connected with above-mentioned collecting unit and led display unit, collecting unit is transferred to microcontroller to gathering after the external signal of coming is handled, and microcontroller calculates, judges the signal of being received, and marks off interval value, call the LED flicker pattern corresponding then, the work of driving LED display unit with this interval value; This power circuit is electrically connected with above-mentioned collecting unit, led display unit and microcontroller, is used to provide their required working powers.

The external signal of gathering is converted to pulse width signal to described collecting unit or the current potential high-low signal is transferred to microcontroller again.

When described collecting unit was the rotating speed collecting unit, the external signal of being gathered was a tach signal.

When described collecting unit was the temperature module, the external signal of being gathered was a temperature signal.

Described led display unit is a plurality of LED lamps of array.

The utility model is compared with technology with existing, its beneficial effect is, the relevant rotating speed or the temperature regime of fan are converted into pulse width signal or current potential high-low signal after the collecting unit collection, and be transferred to microcontroller, microcontroller calculates, judges and divide interval value to these signals, call inner and this interval value corresponding LED flicker pattern of microcontroller then, the work of driving LED display unit.By this, can understand the rotating speed or the temperature regime of fan intuitively,, reach the purpose of monitoring or caution in time to make counter-measure by its flicker pattern.And because that microcontroller because of the innovation of technical matters, is used in every field is very extensive, its price is very easy, is more or less the same with common numeral commonly used, does not therefore have deficiency on the cost in application of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:

See figures.1.and.2 and be depicted as the utility model one embodiment, specifically include power circuit 101, microcontroller (MCU) 102, led display unit 103 and rotating speed collecting unit 104, this rotating speed collecting unit 104 and led display unit 103 are connected on the microcontroller 102, provide working power by power circuit 101 for microcontroller 102, led display unit 103 and rotating speed collecting unit 104, rotating speed collecting unit 104 is transferred to microcontroller 102 with rotation speed of the fan 105 signals that collect.Wherein, the tach signal that rotating speed collecting unit 104 is collected, pulse width signal that can produce or the current potential high-low signal that is produced during by potentiometer control rotating speed for the mode of modulation control; Led display unit is a plurality of LED lamps of array.

Microcontroller 102 calculates, judges comparison and divide interval value that the interval value of present embodiment is divided into three sections at tach signal, be respectively below 1000 rev/mins, between 1000 to 2000 rev/mins and more than 2000 rev/mins.

Be integrated with LED flicker pattern subroutine in the microcontroller 102, if the high rotating speed more than 2000 rev/mins, microcontroller 102 is transferred corresponding LED flicker pattern subroutine, and output control signal driving LED display unit 103 shows the flicker frequencies flicker pattern of having a ride on a horse faster; If the medium speed between 1000 to 2000 rev/mins, microcontroller 102 is transferred corresponding LED flicker pattern subroutine, and output control signal driving LED display unit 103 shows the flicker pattern of the circulating effect that flicker frequency is general; If the slow-speed of revolution below 1000 rev/mins, microcontroller 102 is transferred corresponding LED flicker pattern subroutine, and output control signal driving LED display unit 103 shows the flicker pattern of the flowing water suburb fruit that flicker frequency is slower.

With reference to Fig. 3 and Fig. 4 is another embodiment's of the utility model concrete structure, present embodiment and last embodiment's difference is, this collecting unit is a temperature module 106, be converted into pulse width signal or current potential high-low signal by the temperature module 106 sense ambient temperature 107 resulting temperature signals, and be transferred to microcontroller 102.Microcontroller 102 calculates, judges comparison and divide interval value at these signals, is divided into three interval values in the present embodiment, be respectively 25 degree following, 25 spend between 45 degree and more than 45 degree.If the above high temperature of 45 degree, microcontroller 102 is transferred corresponding LED flicker pattern subroutine, and output control signal driving LED display unit 103 shows have a ride on a horse the faster flicker pattern of effect of flicker frequencies; If 25 spend to the medium temperature between 45 degree, microcontroller 102 is transferred corresponding LED flicker pattern subroutine, and output control signal driving LED display unit 103 shows the flicker pattern of the circulating effect that flicker frequencies are general; If the following low temperature of 25 degree, microcontroller 102 is transferred corresponding LED flicker pattern subroutine, and output control signal driving LED display unit 103 shows the flicker pattern of the flowing water suburb fruit that flicker frequency is slower.
