Abstract
The invention discloses an automatic ceiling fan, and belongs to the field of household appliances. A control part of the automatic ceiling fan is composed of an infrared sensor, a 80C51 single-chip microcomputer, a negative temperature coefficient thermistor, a stepping motor and a ceiling fan gear switch, wherein the infrared sensor and the negative temperature coefficient thermistor are connected with the input end of the 80C51 single-chip microcomputer, the stepping motor is connected with the output end of the 80C51 single-chip microcomputer, and the stepping motor is connected with the ceiling fan gear switch. The automatic ceiling fan has the advantages that the infrared sensor is used for sensing whether people are in a room or not, and then the ceiling fan is accordingly controlled to start and stop; after the ceiling fan is started, the 80C51 single-chip microcomputer controls the stepping motor to drive and rotate the switch to adjust the rotating speed of the ceiling fan according to input signals of the negative temperature coefficient thermistor and the room temperature, and then automatic start and stop and automatic speed adjustment of the automatic ceiling fan can be achieved according to the external environment.
Description
Technical field
The present invention relates to a kind of automatic ceiling fan, specifically apply a negative tempperature coefficient thermistor, an infrared sensor, a stepper motor, a 80C51 single-chip microcomputer, a kind of automatic speed regulation of a ceiling fan driving switch formation and the ceiling fan of auto-open-close, belong to household appliance technical field.
Background technique
Along with scientific and technical development, air-conditioning has started slowly to popularize, but still very common at rural area, school and many public arenas ceiling fan, ceiling fan in the market is normally controlled the rotating speed of ceiling fan by the switch on wall, and there is sometimes the situation that in a room, nobody's ceiling fan but turns at that always, caused the waste of resource.For realize ceiling fan automatic startup, stop and according to room temperature automatic speed regulation, in the urgent need to a kind of automatic speed regulation and auto-open-close ceiling fan, but there is no in the market such ceiling fan.
Summary of the invention
For above-mentioned deficiency, the invention provides a kind of automatic ceiling fan.
The present invention is achieved by the following technical solutions: a kind of automatic ceiling fan, its control section is comprised of infrared sensor, 80C51 single-chip microcomputer, negative tempperature coefficient thermistor, stepper motor, ceiling fan driving switch, it is characterized in that: infrared sensor is connected with the input end of 80C51 single-chip microcomputer with negative tempperature coefficient thermistor, stepper motor is connected with the output terminal of 80C51 single-chip microcomputer, and stepper motor is connected with ceiling fan driving switch.
The usefulness of this invention is: this automatic ceiling fan can utilize in infrared sensor perception room, whether someone controls the startup of ceiling fan and stops, after ceiling fan starts, 80C51 single-chip microcomputer drives rotary switch to regulate the rotating speed of ceiling fan according to the input signal of negative tempperature coefficient thermistor according to room temperature control step motor, thereby make this automatic ceiling fan realize and automatically opening according to external environment, close and automatic speed regulation, ceiling fan has not only been saved electric energy after having this function, avoid resource waste and also can be according to room temperature automatic speed regulation, the life being convenient for people to without people's manual governing makes this design have more hommization.
Accompanying drawing explanation
Accompanying drawing 1 is fundamental diagram of the present invention.
In Fig. 1,1, infrared sensor, 2,80C51 single-chip microcomputer, 3, negative tempperature coefficient thermistor, 4, stepper motor, 5, ceiling fan driving switch.
Embodiment
As shown in the figure, a kind of automatic ceiling fan, its control section is comprised of infrared sensor 1,80C51 single-chip microcomputer 2, negative tempperature coefficient thermistor 3, stepper motor 4, ceiling fan driving switch 5, infrared sensor 1 is connected with the input end of 80C51 single-chip microcomputer 2 with negative tempperature coefficient thermistor 3, stepper motor 4 is connected with the output terminal of 80C51 single-chip microcomputer 2, and stepper motor 4 is connected with ceiling fan driving switch 5.
When this device work, by whether having people in infrared sensor 1 induction room, send unlike signal to 80C51 single-chip microcomputer 2,80C51 single-chip microcomputer 2 is controlled the open and close of ceiling fan according to the difference of signal.Someone time, which gear 80C51 single-chip microcomputer 2 should use according to the signal judgement ceiling fan of negative tempperature coefficient thermistor 3 input, by control step motor 4, drives ceiling fan driving switch 5 to switch corresponding gear.In room, 80C51 single-chip microcomputer 2 drives ceiling fan driving switch 5 to forward " stopping " gear to according to the input signal control step motor 4 of infrared sensor 1 during no one, thereby completes the automatic speed regulation of ceiling fan and the function of auto-open-close.
For the ordinary skill in the art, according to instruction of the present invention, in the situation that not departing from principle of the present invention and spirit, within the change that mode of execution is carried out, modification, replacement and modification still fall into protection scope of the present invention.
