Li Shixiang biological nature standard values in microcontroller compare, in the range of allowable error（Such as 5% frequency error）, sentence
Detected if breaking and to whether there is when having wind in Li Shixiang test environments, between Chinese chestnut branch, between leaf and branch, between leaf just
It can pat, rock vibration and rub, produce noise, influence is produced on audio detection and audio frequency detection.For from being superimposed noise
Audio and sound signal in successfully extract primary biological characterisitic parameter, therefore, microprocessor will be according to wind speed（Wind scale）
Size different methods is taken respectively to separate and extract primary biological characterisitic parameter.The wind speed measured when air velocity transducer compared with
It is small（Such as force 3 wind and following）When, at this moment noise signal frequencies are more much smaller than primary biological characterisitic parameter, to audio detection harmony
Frequency detection information is not enough into big influence.Microprocessor will use Fourier transform automatically, by audio and acoustic frequency sensor
Input signal analyzed, original signal can be just analyzed well, Li Shixiang in audio detection and audio frequency detection information is extracted
Primary biological characterisitic parameter, judge to whether there is and detect Li Shixiang；When the wind speed that air velocity transducer is measured is larger（Such as four-six
Level wind）When, at this moment noise signal frequencies are close with primary biological characterisitic parameter, at this moment using Fourier transform, analysis and extraction
Go out primary biological characterisitic parameter and there will be very big error.Therefore, microprocessor by it is automatic using least square method come to audio with
The input signal of acoustic frequency sensor is analyzed, and the stop criterion of 2 Norm minimums is utilized on the basis of observing matrix, by asking
Linear equation is solved, the characteristic parameter of close signal composition is picked out（Such as amplitude, phase angle）.So as to effectively recognize and extract
Li Shixiang primary biological characterisitic parameter in audio detection and audio frequency detection information, judges to whether there is and detects Li Shixiang.
It is above-mentioned it is various in the case of, if detecting Li Shixiang, the microcontroller of slave computer driving alarm module sends early warning,
And show detection information upload host computer；Meanwhile, the red flicker alarm flicker of the UI operation main interfaces of host computer, text
Zone of alarm prompting " is please noted！Have detected that Li Shixiang." text warning information；Orientation viewing area in Fig. 3 shows substantially square
Position.Time of fire alarming is set as that (user can independently set time of fire alarming length to 60s according to actual conditions.), system after 60 s
Automatic closing and alarm device.If wanting to check Li Shixiang specific insect pest position, by by clicking on " the sound wave in UI operation main interfaces
Sense channel inquires about button " and " audio detection passage inquires about button ", into corresponding sub- UI interfaces.Check institute on sub- UI interfaces
The green changeable colour of the two sets arranged in parallel set, button can be shaken, which or which button is changed into red and continuous from green
When ground is shaken, just explanation respective sensor closely detects Li Shixiang, just can determine that in garden installation site according to sensor
The specific scene of insect pest.
In the present embodiment, to the programmings of the arithmetic processing methods such as Fourier transform and least square method using MATLAB come
Realize, generating DSP c program using MATLAB and importing in the engineering that the present embodiment DSP is created, compiling is downloaded in dsp,
It is incompatible between MATLAB programs and DSP to solve.When the wind speed that air velocity transducer is measured is bigger（Such as seven grades and with windward）When,
At this moment Li Shixiang will not both gnaw Chinese chestnut tree tender tissue, and also have no ability to stretch open wings flies toward on tree.At this moment microprocessor
Automatic shutdown.
In the present embodiment, wind speed and direction information in Chinese chestnut garden is gathered using wind speed measurement module, and sends into microcontroller
Device is handled and analyzed, and can greatly reduce the rate of false alarm of detection.Microcontroller is exported, and on the one hand stores data in extension
Flash data memory module（EEPRAM）In, be easy to user store parameter by expanding USB interface export, development cloud extends
Or other follow-up study analyses.On the other hand, to host computer output display, and alarm is driven to send alarm signal.
In the present embodiment, the sensor in Li Shixiang detection means（Audio sensor and sonic sensor）Deployment scenarios
It is as follows：This on-line detecting system is placed in the centre position of (such as 0.07 hectare) in the Chinese chestnut plantation of certain area, and with this
For origin, garden is divided into four regions up and down, using origin as starting point in each region, using fan-shaped distributed knot
Structure, audio sensor and sonic sensor in couples, relatively evenly by numbered sonic sensor（Such as CRY2110/2112
Series, 16 or 32）, audio sensor (such as MP34DT02TR series, 16 or 32) be placed on branch and trunk, sound wave is passed
The sensing unit of sensor is close to branch or clamps branch, and audio sensor leans against trunk vibration and faced outwardly, and is respectively intended to collection plate
In chestnut plantation in Li Shixiang gnaw Chinese chestnut tree tender tissue acoustical signal and emergence after Li Shixiang adults fly to Chinese chestnut tree when
Audio signal when wing is agitated.1 wind speed measurement sensor is respectively placed in the pact centre position in four regions（Such as LVFSC systems
Row）.
Shown in Figure 7, in the present embodiment, the power module is powered to whole system, the power supply to power module
Using solar energy combined power supply way.One is to pass through 12V chargers by 220V AC power supplies, gives 12V lithium cell chargings；Two are
By solar powered.Influenceed fluctuation larger by light intensity incident angle because photovoltaic panel is exported, directly damaged using to lithium battery
It is bad larger, therefore, to set up counterflow-preventing between photovoltaic panel and lithium battery and overcharge controller.When charge voltage range and 12V
When the range of nominal tension of battery is close, charging process can be made to be operated near maximum power point, its charge efficiency is higher.For this
According to the fill factor, curve factor of photovoltaic panel panel, from the photovoltaic panel that maximum power point voltage is Vmpp ≈ 18V.
In the present embodiment, the load that microcontroller is driven is more, interfering, carrying during for each loaded work piece of reduction
The stability of high system, different according to the operating voltage of each functional module, power module of the present invention will power to functional module and adopt
Use independently-powered mode.The output voltage of the 12V chargeable lithium cells is divided into three tunnels：Wherein：The first via is through high efficiency line
Property three linear voltage-stabiliser tubes (such as AMS1117-3.3) drop voltage stabilizings after be divided into two-way, it is filtered all the way after output 3.3V, to DSP's
I/O is powered, and another road exports 1.9V after adjusting 10K potentiometers high pressure, filter filtering through regulating circuit, and the kernel to DSP is supplied
Electricity；Second tunnel exports 5V after dropping voltage stabilizing, filtering through DC-DC insulating power supply modules B1205S-2WR3, to sonic detection module, report
The alert power supply such as module and wind speed measurement module；3rd tunnel adjusts 10K potentiometers through regulating circuit LM2576-ADJ, through voltage stabilizing, filter
3V is exported after ripple, the power supply such as low-power consumption audio detection module is given.
Although above with general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements, belong to the scope of protection of present invention without departing from theon the basis of the spirit of the present invention.
