The taxi self-help inquiry system based on wavelet exchange is convenient for taxi drivers to obtain the latest road conditions by use of a high-reliability device, and therefore, the taxi drivers can select driving routes conveniently and the urban traffic jam can be solved.
Description
Technical field
The present invention relates to a kind of taxi self-service query system, be specifically related to a kind of taxi self-service query system exchanged based on small echo.
Background technology
Wavelet transformation, very large advantage is had with traditional Fourier transform is similar, wherein maximum 2 are exactly, and it the multiplying be converted to differentiating in time domain in frequency field, just can be converted into algebraic equation to process for general Differential Equation with Constant Coefficients like this.Be exactly a bit that it can be converted to multiplying the convolution algorithm of function in addition, it can simplify the process to the linear system with translation invariance like this.But Fourier transform has its limitation, it is helpless for the ordinary differential equation of variable coefficient, also little for general linear system Fourier transform use, can not the feature of reaction signal in local time.In order to solve or partly address these problems, there has been proposed the thought of wavelet transformation, its inherits the lot of advantages of Fourier transform on the one hand, overcomes the weakness that Fourier transform lacks locality in addition to a certain extent.Its feature is exactly that its transforming function transformation function has window feature.
Based on the above, wavelet conversion technology can be applied to vehicle supervision department, the grasp to urban transportation real-time information is realized in conjunction with modern computer application technology means, and real-time road condition information is sent on taxi driver's mobile phone, taxi driver is made to grasp up-to-date road conditions when going on a journey, be convenient to taxi driver and select suitable traffic route, be convenient to urban transportation reasonable diffluence.
