Embodiment:
Sound wave attracts part:
Biological Principles:
Male mosquito can be by the deception of the sound wave of 300 ~ 400Hz, and they can take for is the sound wave that female mosquito sends, thereby assembles to sound source, utilizes these characteristics to concentrate and kills male mosquito, destroys its population balance, destroys its [Dan, thereby reaches ecocidal effect.
Circuit theory:
At first using waveform generator, produce the waveform of this frequency, can be sinusoidal wave, triangular wave, and the multi-harmonic-oscillations waveforms such as square wave, then the rate of doing work is amplified, and drives sounding component.Waveform generator can be the triode oscillating circuit, also can use the multivibrator integrated circuit, can also synthesize (DDS) technology with numerical frequency.
Waveform generator preferably can be realized the Field adjustment to frequency, and the frequency of the mosquito sensitivity of (region that is limited with hundreds of km) is slightly different because different geographical, and the Field adjustment frequency can realize better drawing the mosquito effect.
To the frequency adjustment of triode oscillating circuit, can pass through control capacittance, resistance realization,
Can realize by regulating its external RC multivibrator integrated circuit (for example 555 time-base integrated circuits),
To the DDS circuit, can realize that these all are known technologies by its stepping phase place is set.
Sounding component can be used coil-moving speaker, also can use the piezo-electric ceramic sounding sheet, or other sounding components, on the unessential basis of other term restrictions, preferentially selects in 300 ~ 400Hz frequency response sounding component preferably.
Laser is killed part:
As shown in Figure 1, when mosquito aloft dances in the air, microcontroller 11 is by camera 14 shootings, can identify mosquito 16, and extract its three-dimensional coordinate, even can accurately locate its wing, then control the The Cloud Terrace 13 of laser instrument 12 and adjust attitude aligning mosquito, and to its Emission Lasers, the heat effect moment destruction mosquito bodily tissue (mainly being moisture and carbohydrate) of laser, or only burning the wing of mosquito--this needs more accurate identification and control, allows it no longer include to bite, the harm of transmitted virus.
Image recognition: two cameras, aim at an aerial zone, they synchronously make video acquisition, form the vision signal on two-way plane, every road signal is made moving object detection, for example use calculus of finite differences, and do target identification, this is by setting up the graphic feature of mosquito, these features can be areas, texture, gray scale, then flying speeds etc. judge in the Real time identification algorithm whether target meets to realize; After being identified as the mosquito target, calculate the real-time center-of-mass coordinate of target, two paths of signals can obtain two center-of-mass coordinates, combine and to calculate mosquito with respect to the three dimensional space coordinate of camera, and then calculate the direction that laser instrument should be aimed at, alignment system according to this result of calculation adjusting laser instrument aims at the mark accordingly, and the Emission Lasers bundle destroys it.
The mosquito Coordinate calculation method is as shown in Figure 2:
Z0 is the physical parameter of video camera, also can obtain with a known distance u, the big or small v0 of picture that is of a size of the thing of v: u/Z0=v/v0.
Here it is parallel to establish two optical axises, and two set of lenses and visual field 21 are equidistant, and wherein the coordinate of corresponding target has following relation
(X+d)/x1=(X-d)/x2=Y/y1=Z/Z0,?y1=y2,?z1=z2=Z0,
Illustrate: when x1=0, X=-d;
When x2=0, X=d;
When y1=0, Y=0.
Separate this equation group, can obtain the coordinate (X, Y, Z) of T, this is the coordinate of mosquito in the space.This coordinate origin is at two set of lenses line mid points.
Alignment system can be the The Cloud Terrace system, also can be the pendulum mirror system.
The Cloud Terrace comprises at least two regulating shafts, and is not parallel each other, and also not parallel, preferably orthogonal with optical axis, laser instrument can be regulated arbitrarily in a solid angle scope like this.Certainly, if diaxon is not parallel, also can realize the twin shaft adjusting, just formula is slightly different.
By the direction that the angle of regulating two axles is regulated laser instrument aiming, the calculating of angle as shown in Figure 5:
Two regulating shaft axis might as well establishing The Cloud Terrace intersect at fixing some L(x3, y3, z3 with laser beam axis),
When target at T(X, Y, Z) time, the level angle of laser (laser horizontal plane xOz plane inner projection with z axle positive direction angle) φ=arctg((X-x3)/(Y-y3)), might as well establish this angle here between positive and negative 90 degree.The calculating of other angular ranges can similarly be derived;
Laser might as well be established this angle here between positive and negative 90 degree at angle (laser and its angle at the horizontal plane xOz plane inner projection) θ of vertical direction=arctg(Y-y3)/Sqrt ((Z-z3) ^2+ (X-x3) ^2).The calculating of other angular ranges can similarly be derived;
Here it is regulates the angle parameter of The Cloud Terrace.
The pendulum mirror system comprises two pendulum mirrors, and two balance staffs, laser optical axis pairwise orthogonal after laser is sent by resonator like this, can be implemented in the interior quick adjustment of a solid angle scope.
It regulates the computational methods that parameter is similar to the The Cloud Terrace system.
The microcontroller software block diagram is as shown in Figure 6:
Entering wait state through initialization after main program main starts, namely do not stop scanning " view data ready flag ", find whether go to identify it after its set is target, and this sign that resets, is that the words of target are calculated its (barycenter) coordinate, aiming, shoots;
The view data of camera acquisition drives microcontroller and produces interrupt signal, Interrupt Service Routine ISR is by this signal enabling, then initialize and the transmission of data (when also may produce interrupt signal one frame data end of transmission), every transmission one piece of data, for example each image channel gathers after the frame data, arrange " view data ready flag ", from ISR, return, continue to carry out main program.
Preferably, can make aim-off calculates:
Because shooting will be through a delay to Emission Lasers, this delay may cause launching light beam misses the target, so aiming will be included the consideration of lead in.Might as well establish the mosquito flight path is linear track, within the relatively shorter time, be rectilinear flight namely, drawing its velocity by the tracking to a period of time of mosquito is (Vx, Vy, Vz)--notice that this is a variable, and the time of the Emission Lasers experience of making a video recording is t, obtain image when 0 moment, can predict that so mosquito has flown to T1(X+Vx.t, Y+Vy.t, Z+Vz.t), should aim at T1 during aiming.Similarly, can do to the flight path of mosquito the prediction of other models, for example high-order prediction, for example acceleration also is foreseeable.
Whole:
Behind the system boot, sonic generator is started working, attract male mosquito sudden, camera begins to gather vision signal simultaneously, video processing unit also begins to distinguish the target that flies, and begins to follow the tracks of when identification result is mosquito, regulates the laser gun direction, finish Emission Lasers pulse when regulating, kill and wound mosquito or destroy the mosquito wing.Whole equipment can be placed on the The Cloud Terrace, to increase operating angle.
