Abstract
The invention discloses an electric fan. The electric fan comprises a fan body; a processor, a fan motor and fan blades are arranged inside the fan body, and a rotary knob and a switch are arranged outside the fan body; the processor is connected with the rotary knob, the switch and the fan motor, and the fan motor is connected with the fan blades; the electric fan further comprises a data collector which is connected with the processor, the data collector collects external environment information and sends the external environment information to the processor, and the processor sends control information to the switch according to the received information to control powering on and powering off of a power supply of the fan motor. According to the scheme, the electric fan is simple in structure, achieves intelligent control, saves electricity, and meanwhile eliminates potential safety hazards.
Description
Technical field
The present invention relates to a kind of electric fan, belong to household appliance technical field.
Background technique
At present, the electric fan on market is various, and each large producer constantly releases electric fan and attracts client's eyeball, on the whole, electric fan mainly comprises manually, two kinds of remote controls, and major part is manually and the remote control combination, and manual fan structure is simple, economical and practical, but need the actions such as manually-operable open and close, rotary head, new line, use and be not that easily remote control electric fan has solved the shortcoming of this respect, realization, in these actions of remote control, has improved convenience greatly.
No matter be manual electric fan or the electric fan of remote control, be all to carry out according to demand manual tune, no matter be direct control, or operate by remote controller, all need manual operation when in use, so still fail to realize the intelligent control of electric fan.Sometimes, use the people of electric fan to go out temporarily, forget the power supply of closing electric fan, at this moment, electric fan will be always in running order, both wasted power supply, has potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention is: a kind of electric fan is provided, has solved the problem that electric fan of the prior art can not be realized intelligent control.
The present invention, for solving the problems of the technologies described above, adopts following technological scheme:
A kind of electric fan, comprise fan body; The inner set handling device of described fan body, fan electromotor, fan page, described fan body outer installment knob, switch; Described processor is connected with knob, switch, fan electromotor respectively, and described fan electromotor is connected with described fan page; Also comprise data acquisition unit, described data acquisition unit is connected with processor, and described data acquisition unit gathers external environmental information and is sent to processor, and described processor to switch, is controlled the on/off of fan electromotor according to the delivering control information received.
Described data acquisition unit comprises infrared senor, temperature transducer, angle transducer, described infrared senor detects the vital sign information of fan front end, described temperature transducer detects indoor temperature information, and processor is according to the break-make of vital sign information and indoor temperature information control switch; Angle transducer detects the angle that fan rotates, and this angle is sent to processor, and described processor is regulated the fan rotation angle automatically according to vital sign information.
Described processor is a kind of in single-chip microcomputer, ARM, FPGA.
Described switch comprises input end, output terminal, control end; Described input end is connected with external power supply, and described output terminal is connected with fan electromotor, and described control end is connected with processor.
Compared to existing technology, the beneficial effect that has of the present invention is:
The present invention is simple in structure, and electric fan manufacturing firm only need increase a small amount of components and parts, can realize the intelligent operation of fan, according to the characteristics of human body, automatically controls switch and the pendulum angle of fan, has realized intelligent control, has saved resource, has got rid of simultaneously potential safety hazard.
The accompanying drawing explanation
Fig. 1 is structured flowchart of the present invention.
Wherein, being designated in figure: 1-fan body; The 2-knob; The 3-switch; The 4-sensor.
Embodiment
Below in conjunction with the technological scheme of accompanying drawing to invention, be elaborated:
As shown in Figure 1,
A kind of electric fan, comprise fan body 1; The inner set handling device of described fan body 1, fan electromotor, fan page, described fan body 1 outer installment knob 2, switch 3; Described processor is connected with knob 2, switch 3, fan electromotor respectively, and described fan electromotor is connected with described fan page; Also comprise data acquisition unit, described data acquisition unit is connected with processor, and described data acquisition unit gathers external environmental information and is sent to processor, and described processor to switch 4, is controlled the on/off of fan electromotor according to the delivering control information received.
Described data acquisition unit comprises infrared senor, temperature transducer, angle transducer, described infrared senor detects the vital sign information of fan front end, described temperature transducer detects indoor temperature information, and processor is according to the break-make of vital sign information and indoor temperature information control switch; Angle transducer detects the angle that fan rotates, and this angle is sent to processor, and described processor is regulated the fan rotation angle automatically according to vital sign information.
Described processor is a kind of in single-chip microcomputer, ARM, FPGA.
Described switch comprises input end, output terminal, control end; Described input end is connected with external power supply, and described output terminal is connected with fan electromotor, and described control end is connected with processor.。
Selecting single-chip microcomputer is the core processor of control centre, the present embodiment is selected the AT89C51 chip, described infrared senor, temperature transducer, angle transducer output signal connect respectively the input port of AT89C51 chip, and the input of switch control end connects the output port of AT89C51 chip.
The working procedure of the present embodiment is as follows:
AT89C51 real time scan input port,
When input signal having been detected, judgement is the signal of which sensor, when infrared senor signal and temperature sensor signal being detected simultaneously, the judgement temperature sensor signal, temperature sensor signal and predefined value are compared, if be greater than predefined value, send control signal, control electric fan work; Judge the angle transducer signal, and according to vital sign information, automatically regulate the rotation angle of electric fan.
When temperature transducer having been detected and the infrared senor signal not detected, electric fan work; While is the process angle sensor signal not.
When the value that temperature sensor signal detected is greater than predefined value, the infrared senor signal detected simultaneously, postpone certain hour judgement infrared senor signal, if still exist, AT89C51 sends control signal, electric fan work.
AT89C51, for the infrared senor signal being detected, postpones the certain hour judgement still for the infrared senor signal being detected, controls electric fan and closes, and prevents the phenomenon that dallies, and has saved electric energy, has ensured safety.
