Accompanying drawing explanation
Fig. 1 is circuit block diagram of the present utility model.
In the drawings, 1, microprocessor 2, human body signal testing module 3, wind direction adjustment module 4, temperature collect module 5, parameter display module 6, speed adjusting module.
Embodiment
The utility model is illustrated below in conjunction with Fig. 1, described wind speed main body cover lower end is provided with base, described microprocessor (1), human body signal testing module (2), wind direction adjustment module (3), temperature collect module (4), parameter display module (5) and speed adjusting module (6) are evenly distributed in base intracavity, and described microprocessor (1) connects human body signal testing module (2), wind direction adjustment module (3), temperature collect module (4), parameter display module (5) and speed adjusting module (6) respectively.
Described human body signal testing module (2) is HC-SR501 human body infrared induction module preferably.
Described temperature collect module (4) is DS18B20 temperature transducer preferably.
Described parameter display module (5) is LCD1602 liquid crystal screen preferably.
Described microprocessor (1) is STC89C52 single-chip microcomputer preferably.
Described microprocessor (1) adopts the STC89C52 single-chip microcomputer of both sides MCU-1 and MCU-2.
During use, the data that MCU-1 passes on to temperature collect module (4) process in real time, show and control to export corresponding pulse-width signal realizes correspondence rotating speed to silicon controlled module.MCU-1 is real time scan key-case simultaneously, carries out classification and controls.MCU-2 then processes the information that human body signal testing module (2) transmits, and judges person body orientation, controls motor and completes position rotating or scope rotation.Communicated by serial ports between MCU-1 with MCU-2, complete fan and close lower than during minimum setting value in unmanned and temperature, detecting that human body exists rear unlatching (meeting temperature range) automatically.
Human body signal testing module (2) adopts five HC-SR501 human body induction modules respectively whether the carrying out in five directions to be had to the detection of people's activity, fan pivot angle about 150 degree, therefore each module controls about 30 degree angles, through rational deployment, control area does not intersect, and can realize wind direction and automatically regulate.
Wind direction adjustment module (3) adopt steering wheel directly carry out wind direction adjustment, steering wheel and fan are directly rigidly connected, fan turns situation and steering wheel completely the same, complete fan head swinging independence control.
Temperature collect module (4) uses digital DS18B20 integrated temperature sensor as the core parts of temperature detection, detects also directly output digit signals process to microprocessor (1) by it.
Speed adjusting module (6) adopts the rotational speed regulation of silicon controlled module realization to 220V load motor.Changed the angle of flow of bidirectional triode thyristor by the dutycycle of control signal, output end voltage is changed, thus the input voltage being applied to electric fan is changed, to regulate the rotating speed of fan, realize the stepless speed regulation of each gear wind speed.
Parameter display module (5) completes display with LCD1602, the key parameters such as real-time display environment temperature, mode of operation, general mode wind speed, are furnished with 4 buttons, one of them is power knob, one for mode switch button is to complete switching that is manual, automatic mode, separately establishes two buttons to carry out manual wind speed plus-minus and regulates.Fan is furnished with five tutorial light simultaneously, for showing person body orientation in real time, makes whole wind speed more directly perceived.
The technical feature of the utility model modules is as follows:
1, human body signal testing module (2): whether adopt HC-SR501 human body induction module to detect in fixed area and have users, the infrared rays sent by human body is judged.Maximum detecting distance is 5m, and each module level angle detecting angle limits is 30 degree, has people then to export high level in surveyed area, otherwise output low level;
2, wind direction adjustment module (3): rotate for controlling fan head swinging, what conventional fan used worm and gear to be connected to realize maximum magnitude with the motor of controlled wind speed carrys out back rotation, for meeting design requirement, part of shaking the head adopts steering wheel to control separately, steering wheel and fan are rigidly connected, and are independent of each other with the motor of controlled wind speed;
3, temperature collect module (4): for carrying out the collection of ambient temperature, use DS18B20 to carry out temperature acquisition, output digit signals, after master control system process, controlled wind speed varies with temperature;
4, speed adjusting module (6): change rotating speed, just must change motor operating voltage.Because control system need realize stepless speed regulation and operating voltage is 220V, therefore adopt ghyristor circuit.Ghyristor circuit changes the silicon controlled angle of flow to change output voltage by pwm signal; and carry out light-coupled isolation to protect master control system; namely correspondence change is automatically carried out by the change controlled wind speed of testing environment temperature; the corresponding rotating speed of each temperature (least unit be degree Celsius); acquiescence maximum temperature values is 35 degree; reach maximum wind speed when 35 degree, temperature keeps maximum wind speed higher than setting maximum value, and temperature maximum can set.Acquiescence minimum value is 25 degree, automatically closes after 25 degree;
5, parameter display module (5): the display mainly carrying out the important parameters such as wind speed, ambient temperature, mode of operation, LCD1602 liquid crystal screen is adopted to show, button is coordinated to carry out the speed switching of pattern switching, general mode, the man-machine interaction on acquiring a certain degree;
6, microprocessor (1): adopt two panels STC89C52 single-chip microcomputer to control, the information such as user location information, ambient temperature, mode of operation of Real-time Collection gained is processed in real time, controlled corresponding function;
7, wind direction adjustment module (3): the user profile of human detection module Real-time Collection corresponding region, 5 corresponding 5 positions of module.When can realize unique user being detected, fan head swinging forwards user region to and stops, if all detect that user exists in multiple region, then from detecting that scope rotation is interregionally carried out to the rightest in the most left region of human body signal.If all testing modules did not all detect the existence of user in one minute, will automatically close, the stream of people's situation when judgement time of one minute uses according to reality sets.
Mode of operation of the present utility model: provide two kinds of mode of operations is intelligent mode and general mode.Intelligent mode gets final product the automatic adjustment of foregoing wind direction and wind speed, and during general mode, carry out maximum magnitude identical with conventional fan is shaken the head and carry out manual key speed governing.Manual mode is mainly used in meeting the demand that user exceeds the corresponding wind speed of ambient temperature.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
