The hardware development instrument of ARM mainly comprises two class emulators, and one is JTAG emulator, and two is full-functional in-circuit emulators.The former is the function of the debugging module utilized in arm processor, is connected with emulator by its jtag boundary scanning mouth, and the emulator of this mode is relatively more cheap, connect more convenient, but owing to debugging by means of only tens lines, thus function has limitation.The JTAG emulator of current arm processor is commercially popular is JEENI and MAJIC of EPI company, and famous German Lauterbach company has a general JTAG/BDM/ONCE emulator TRACE32-ICD also to can be good at supporting ARM series processors.For full-functional in-circuit emulator, replace the CPU on Target Board completely due to its letter proper head, thus function is very powerful.But this kind of emulator is in order to simulation clock speed higher than the processor of 100MHz, usually can adopt extremely complicated design and processes at full speed, and thus its price comparison is expensive.
In addition, wavelet filter is the wave filter based on wavelet transformation, and compared with converting with Fourier, wavelet transformation is the partial transformation of space (time) and frequency, thus can information extraction from signal effectively.Multiple dimensioned refinement analysis can be carried out to function or signal by calculation functions such as flexible and translations, solve Fourier and convert indeterminable many difficult problems.Wavelet transformation contacted by multiple subjects such as applied mathematics, physics, computer science, Signal and Information Processing, image procossing, seismic prospecting.Mathematician thinks, wavelet analysis is a new branch of mathematics, and it is the perfect crystallization of functional analysis, Fourier analysis, Spline analysis, numerical analysis; Signal and information processing expert think, a kind of new technology of m-dimensional analysis and multiresolution analysis when wavelet analysis is, its research in signal analysis, phonetic synthesis, image recognition, computer vision, data compression, seismic prospecting, air and ocean wave analysis etc. all achieves the achievement of scientific meaning and using value.
The main purpose of signal analysis finds a kind of simple and effective signal transformation method, and the important information that signal is comprised can display.Wavelet analysis belongs to the one of signal time frequency analysis, and before wavelet analysis occurs, Fourier transform is most widely used general, a kind of analysis means that effect is best in signal transacting field.Fourier transform is the instrument that time domain transforms mutually to frequency domain, from physical significance, the essence of Fourier transform be this waveform resolve into the sine wave of different frequency superposition and.This important physical significance of Fourier transform just, determines the unique status of Fourier transform in signal analysis and signal transacting.Fourier transform uses the sine curve ripple of all unlimited stretching, extension in the two directions as orthogonal basis function, periodic function generate fourier series, aperiodic function generate fourier integral, Fourier transform is utilized to do spectrum analysis to function, reflect the time frequency spectrum characteristic of whole signal, disclose the feature of stationary signal preferably.
Wavelet transformation is a kind of new transform analysis method, the thought of its inherit and development short time discrete Fourier transform localization, overcome again window size not with shortcomings such as change of frequency simultaneously, can provide one with " T/F " window of frequency shift, be the ideal tools of carrying out signal time frequency analysis and process.Its main feature is can the feature of abundant some aspect of outstanding problem by conversion, therefore, during the conversion that the discrete digital algorithm that wavelet transformation is obtained for successful application, particularly wavelet transformation has in a lot of fields been widely used in many problems is studied.From then on, wavelet transformation more and more causes the attention of people, and its application is come more and more extensive.
Adopt vehicle-mounted agricultural chemicals automatic sprinkler system of the present invention, low for existing agricultural chemicals artificial spray pattern automatization level, to farmland and the easy hurtful technical problem of operating personnel, use vehicle as agricultural chemicals transport and sprinkling platform, the crop map picture of captured in real-time is analyzed, judge the agricultural chemicals dosage needed for current crops, automatically carry out pesticide spraying, avoid manual operation, accelerate pesticide spraying speed, thus be more suitable for the quick spray medicine in large area farmland.
Be understandable that, although the present invention with preferred embodiment disclose as above, but above-described embodiment and be not used to limit the present invention.For any those of ordinary skill in the art, do not departing under technical solution of the present invention ambit, the technology contents of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solution of the present invention, or be revised as the Equivalent embodiments of equivalent variations.Therefore, every content not departing from technical solution of the present invention, according to technical spirit of the present invention to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belongs in the scope of technical solution of the present invention protection.
