Detailed description of the invention
As shown in Fig. 1 ~ Fig. 4, a kind of vertical electric fan with two-dimentional automatic tracing ability, including human detection module a, LCD LCD MODULE b, keyboard input module c, motor drive module d, MCU control module e.
MCU control module e connects human detection module a, LCD LCD MODULE b, keyboard input module c and motor drive module d respectively.
Described human detection module a includes being arranged on the dividing plate 8 on electric fan surface, multiple pyroelectric infrared sensor 9, and pyroelectric infrared sensor 9 is used for detecting and gathering human body signal；
Motor drive module d connects motor module, and described motor module is arranged on electric fan support 7, and described motor module includes horizontal stepper motor 1, longitudinal motor 2.
Described electric fan support 7 is provided with horizontal worm screw 6, horizontal worm gear 4, and horizontal worm screw 6 is meshed with horizontal worm gear 4；Horizontal stepper motor 1 is coaxially connected with horizontal worm screw 6.
Described electric fan support 7 is provided with longitudinal worm screw 5, longitudinal worm gear 3, and longitudinal worm screw 5 is meshed with longitudinal worm gear 3.Longitudinal motor 2 is coaxially connected with longitudinal worm screw 5.
The dividing plate 8 on described electric fan surface is a cross metal partion (metp), the little circular portion in centre on electric fan surface utilizes metal partion (metp) to be isolated into four regions, and four regions are respectively mounted the first pyroelectric infrared sensor A, the second pyroelectric infrared sensor B, the 3rd pyroelectric infrared sensor C, the 4th pyroelectric infrared sensor D.
Described MCU control module e is the low-power scm of MSP430F149 type, is arranged on electric fan rear portion.
Described LCD LCD MODULE b is three and half liquid crystal display screen 8 field LCD liquid crystal display screens.
Described keyboard input module c adopts common Independent keys.
Described motor drive module d is L298N motor drive module.
Described pyroelectric infrared sensor is HC-SR501 pyroelectric infrared sensor.What adopt is full-automatic sensing, then exports high level when people enters its induction range, and people leaves its induction range then automatic time delay and closes high level, output low level.HC-SR501 pyroelectric infrared sensor has two kinds of triggering modes, this utility model adopts repeatable triggering mode, namely after sensing output high level, in delay time section, if there being human body movable in its induction range, then output is always maintained at high level, until people leaves just time delay and transfers high level to low level.This induction module can be postponed after the activity each time of human body being detected a delay time section automatically, and with the last movable time be delay time starting point.
Four pyroelectric infrared sensors are separated by metal partion (metp), work independently, unaffected from each other.Such as, when human body is moved to the left time, then the sensor on right side does not receive signal, and the sensor in left side then can receive signal；Now just can control horizontal stepper motor 1 so that electric fan is to anticlockwise, until right sensor also can detect signal.
When in the process that people sits down from standing to, owing to the sensor on top can not receive signal, and the sensor of bottom can receive signal, now control longitudinal motor 2 to rotate, electric fan is rotated down and is directed at human body, and then make the electric fan in the two-dimensional direction can the position of real-time tracing human body.
As shown in Figure 2, if left and right two pyroelectric infrared sensors sense human body movement in the horizontal direction, then signal passes through Single-chip Controlling horizontal stepper motor 1.If in like manner upper and lower two pyroelectric infrared sensors sense the change of human body position in vertical direction, then signal passes through Single-chip Controlling longitudinal direction motor 2, horizontal stepper motor 1 is coaxially connected with horizontal worm screw 6, by the rotation rotating the horizontal worm screw 6 of drive of horizontal stepper motor 1, installing engaging of gear again through horizontal worm screw 6 with horizontal worm gear 4 drives horizontal worm gear 4 to rotate, horizontal worm gear 4 is welded on the first carrier unit 7A, rotating thus driving electric fan motion in the horizontal of horizontal worm gear 4.In like manner, longitudinal motor 2 is coaxially connected with longitudinal worm screw 5, by the rotation rotating the longitudinal worm screw 5 of drive of longitudinal motor 2, installing engaging of gear again through longitudinal worm screw 5 with longitudinal worm gear 3 drives longitudinal worm gear 3 to rotate, longitudinal worm gear 3 is welded on the second carrier unit 7B, rotating thus driving electric fan motion in the vertical of longitudinal worm gear 3.It is finally reached control electric fan up and down four purposes that orientation moves, finally realizes electric fan tracker body position in two dimensional surface.
