Abstract

The invention patent discloses a private parking space system based on voice recognition. The main technical scheme of the private parking space system is that when a car drives close to a private parking space of a car owner, voice recognition equipment is used for scanning a voice of the car owner, then performing information processing and identification on the voice, and comparing the voice with voices pre-stored in the system; when the voice recognition equipment judges that the voice is one of the voices of persons pre-stored by the car owner, a rotary motor for controlling the parking space opens the parking space to park the car in the parking space; and when the car leaves the parking space, the rotary motor is continuously controlled by another set of circuit system to close the parking space so as to wait for continuously repeating a voice recognition process after the car approaches next time. By adopting the system disclosed by the invention, the time of driving the car into the parking space can be saved, and the efficiency and convenience of the car owner can be improved.

Description

A kind of private stall system based on speech recognition

Technical field:

The present invention relates to a kind of private stall system, especially based on the stall system of speech recognition technology.

Background technology:

Speech recognition technology, be also referred to as automatic speech recognition Automatic Speech Recognition, (ASR), its target is computer-readable input by the vocabulary Content Transformation in the voice of the mankind, such as button, binary coding or character string.Different from Speaker Identification and speaker verification, the latter attempts identifying or confirm to send the speaker of voice but not wherein comprised vocabulary content.The application of speech recognition technology comprises phonetic dialing, Voice Navigation, indoor equipment control, voice document searching, simple dictation data inputting etc.Speech recognition technology as mechanical translation and speech synthesis technique combine, can construct more complicated application with other natural language processing techniques, and such as voice are to the translation of voice.Before invention on computer, the imagination of automatic speech recognition has just been put on agenda, and early stage vocoder can be considered the blank of speech recognition and synthesis.And " Radio Rex " toy dog that generation nineteen twenty produces may be speech recognition device the earliest, when the name of this dog is called time, it can eject from base.The speech recognition system based on robot calculator is the earliest the Audrey speech recognition system developed by AT & T Bell Laboratory, and it can identify 10 English digitals.The resonance peak in voice is followed the tracks of in its recognition methods.This system obtains the accuracy of 98%.To generation nineteen fifty end, gram probabilities adds in speech recognition by the Denes of London institute (College of London).In generation nineteen sixty, artificial neural network has been introduced into speech recognition.Two quantum jumps in these epoch are linear predictive coding Linear Predictive Coding (LPC), and dynamic time warping Dynamic Time Warp technology.The most important breakthrough of speech recognition technology is the application of Hidden Markov Model (HMM) Hidden Markov Model.Propose relevant mathematical reasoning from Baum, through the research of the people such as Labiner, the Li Kaifu of Carnegie Mellon University finally achieves first large vocabulary speech recognition system Sphinx based on Hidden Markov Model (HMM).After this speech recognition technology does not depart from HMM framework strictly speaking.Although researchist attempts " dictation machine " to promote for many years always, speech recognition technology also cannot support unlimited field at present, the dictation machine application of unlimited speaker.

China's the Research of Speech Recognition work is started in the fifties, but development in recent years is very fast.Research level also progressively moves towards practical from laboratory.Performed national 863 Program from 1987 after, National 863 intelligent computer expert group is the special project verification of speech recognition technology research, every two years rolls once.The research level of China's speech recognition technology, substantially with external synchronous, technically also have the characteristic and advantage of oneself, and reaches advanced world standards at Mandarin speech recognition.The scientific research institutions such as Institute of Automation, CAS, acoustics institute, Tsing-Hua University, Peking University, Harbin Institute of Technology, Shanghai Communications University, Chinese University of Science and Technology, Beijing University of Post & Telecommunication, the Central China University of Science and Technology have laboratory to carry out the research of speech recognition aspect, and wherein representative research unit is department of electronic engineering, tsinghua university and pattern-recognition National Key Laboratory of automation research institute of the Chinese Academy of Sciences.Department of electronic engineering, tsinghua university voice technology and ASIC-based seminar, the accuracy of identification of the unspecified person mandarin connected digit Continuous Speech Recognition System of research and development, reaches 94.8%(random length numeric string) and 96.8%(fixed length numeric string).In the reject rate situation having 5%, system recognition rate can reach 96.9%(random length numeric string) and 98.7%(fixed length numeric string), this is one of recognition result that the world is best at present, and its performance is close to realistic scale.The discrimination of 5000 word mailbags check Speaker-independent continuous speech recognition systems of research and development reaches 98.73%, and first three selects discrimination to reach 99.96%; And can identify that bilingual is talked about in mandarin and Sichuan, reach real requirement." sky language " Chinese speech series of products---PattekASR towards different computing platforms and application that Institute of Automation, CAS and affiliated pattern science and technology (Pattek) company thereof have issued that they jointly release for 2002, finishes the history that Chinese speech recognition product is since nineteen ninety-eight monopolized by offshore company always.Speech recognition technology develops into today, and particularly medium and small vocabulary signer-independent sign language recognition system identification precision is greater than 98%, just higher to the accuracy of identification of particular person speech recognition system.These technology can meet the requirement of application usually.Due to the development of large scale integrated circuit technology, the speech recognition system of these complexity also can make special chip completely, produces in a large number.In west economy developed country, a large amount of speech recognition products has come into the market and service field.Some users hand over mechanical, electrical phone, mobile phone to contain speech recognition dial feature, also have the products such as voice memo basis, Intelligent toy with speech sounds also to comprise speech recognition and speech-sound synthesizing function.People can inquire about relevant air ticket, tourism, bank information by telephone network speech recognition spoken dialogue system, and obtain good result.Investigation statistics shows that the performance of people to the information inquiry service system of speech recognition of nearly more than 85% is satisfied with.Can predict that, in nearly 50 to ten years, the application of speech recognition system will be more extensive.Various speech recognition system product will occur commercially.People also by oneself tongue of adjustment to adapt to various recognition system.Also can not produce in a short time and have the speech recognition system comparable with people, build up such system and remain the large challenge of of facing mankind, we can only advance towards the direction of improving speech recognition system step by step a step by a step.When be then be difficult to prediction as a speech recognition system perfect as people can be set up.Just as in the sixties, who can predict again today, and very large scale integration technology can produce so large impact to our society.

In countries in the world, parking difficulty is a problem always.How the U.S. is a country being called as on " wheel of the bus ", if do not have parking lot, is difficult to their date of imagination mistake.So in U.S.'s major part city, business and uptown parking stall arrange and management, all take much count of.Especially in Xincheng District, the total area in parking lot and the quantity that can stop are through accurate Calculation, its ability not only includes maximum lorry turnover space and maximum accommodation client vehicle flowrate, also leaves in advance in disaster moment unobstructed effective fire escape and relief space.Increase parking stall year in year out: taking care of the pence is the rule of a constancy, and this rule is few on some parking stalls of the U.S., the place of frequent parking difficulty just shows importance.If you to rent a house son and buy apartment in the U.S., be a condition of having very much an advantage with parking stall, usually all can be placed on visibility point, as the attraction of the client that solicits in house for rent and advertisement of buying house.Reader may be had to ask, one has become the city of scale, how could take care of the pence and to increase parking stall? want them to pull down a house? really, New York is in urban renewal, the dilapidated cannot repaired in originally crowded old town in a planned way sets up parking lot after removing.When the new building of construction, stop every parking stall had especially, through accumulation for many years, the parking difficulty of old liberated area resident, progressively carries out adjusting and being resolved.Parking stall, market at night is hired out: the restricted parking area of the U.S. is all oneself price, and government department does not interfere, and unique requirement is must in Entrance place marked price.The charge of short time temporary parking is the highest.Calculated more than 24 hours and park for a long time, price is relatively lower.Some parking lots, also to stable frequent customer, are sold more cheap " parking stall monthly ticket ", and total price is 1/1 to four/3rd of price at ordinary times.In addition, all parking lot is provided for oneself in the most of market of the U.S..After closing in market, these places all vacant nights, so these parking lots all can be hired out night, price general charged is not too high, and condition is before market business in morning, must leave.In the U.S., curb parking must play table charging daytime.Conveniently evening, resident was stopped, and regulation is to certain hour in evening usually, stop and do not need to play table timing again, and all day on Sunday is all free.Self-reliance is pioneered an enterprise with painstaking efforts: in Bostonian Brookland district, automobile can not spend the night in roadside according to the rules, arbitrarily can not take walkway, can not block the doorway in shop.The clever people of many brain melons is just trimmed to parking stall the vacant lot that the house property doorway of oneself is used as garden, hires out with the monthly price of 150 to 200 dollars.Some university students oneself do not have car, the parking space rented with house are subleted yet.Japan's area is only equivalent to 1/26th of China, and but have 7,800 ten thousand automobiles, especially Tokyo and surrounding area thereof have converged more than 2,200 ten thousand automobiles especially.Therefore, Japanese also racks one's brains in order to the problem solving parking difficulty.Do not have parking stall not to registering the license: the law that Japanese government only relates to parking aspect just has five or six more than.Specify according to Japan Law, individual or unit all must provide the proof having fixing parking stall when buying car, what this fixing parking stall had both been had by oneself also can lease for a long time, parking stall must within the scope from unit or 500 meters to 2000 meters, residence, otherwise refusal is registered the license to new car by traffic control department.For stopping random parking, traffic control department can issue new car parking stall certification mark, so that the parties concerned check at any time.The law of Japan also specifies building plans, and 250 square metres of floor area of building as every in Inner city join 1 parking stall, and general area is every 200 square metres and joins 1 parking stall.Reduce tax to private parking lot: government, in order to solve parking difficulty problem, payes attention to encouraging to guide private park construction, reduces or remits the taxes to parking lot for money.In the section that some are bustling and crowded especially, the principle that Japanese government actively advocates " small and scattered ", does not advocate that " the flocking together " in parking lot sets up, and particularly encourage operator Duo Jian sky parking, therefore in Japan, some parking lots only have two or three parking stalls.Evening, curb parking was free: in order to be made good use of on the potential parking stall in roadside, and all wider at road, that vehicle flowrate is less section, Japanese each city is provided with provisional charged parking stall.Daytime stops in these parking stalls, the longest can not more than one hour.But once to evening, these parking stalls are then all free to be opened to car owner.Such as, major part curb parking position in Tokyo is all late 7 is free time section up to next day morning 7 time.In old liberated area, London, famous when road is narrow.Many people can find, the undersized car of British preference, such as mini mono-class, also this reason just.Can see daytime in addition on many two-lane roads, yellow line both sides in the middle of road, are decorated with the stop line of oblique direction to the car, and indicate and can limit down time.This track is exactly common runway at ordinary times, and other roads are as good as, and in, only sees these parking lattice the stipulated time in the evening, and gush has expired various family expenses vehicle quickly, only stays roadside to lean on the road of buildings side for vehicle pass-through.It is large that this mode meets parking at night demand in city, and solve again the problem that land for building, there deficiency can not build too many stopping pad, to morning, these cars be parked in the middle of road leave on time, and there reverts to fast traffic lane again, and car is sent a car past.And non-peak hours/period at night, single track driving is enough to meet traffic needs, also can not hinder evacuating personnel and fire fighter's fire fighting because of being fully parked with in roadside the emergency condition such as automobile, breaking out of fire and rescuing people.In the residential quarter that Russia is common, resident, in order to the parking stall of " circle " a piece oneself, simply directly buys an easy aluminium alloy garage.In the old residential quarter in Moscow city, in disorder little garage has just become a scape.Near these communities, also have the private car park eating " parking meal ", owners enclose ground one with iron bar, spread cement, just can impose parking fee to residents, even if this simple and crude open parking ground, average every day also will pay the parking fee being roughly equal to 40 yuans.To parking difficulty problem, Moscow city adds parking stall, to the heavy punishment installed parking meter in addition of random parking phenomenon.Except major trunk roads, in community, of an antique style Russia old-fashioned street, it is all free for stopping in curbside, be built up in large supermarket and the market in Moscow, also all attaching free parking area allows guests enjoy material benefit, only have the underground parking that the business office building of an inch of land is an inch of gold can incidentally be charged, but general charge also all enjoys 10%, the even property discount of 20%.Also there is discount in some parking lot, Moscow, and long term stop can save the expense of 10% to 20%.The motorcycle lane side of Australia road two way, has a parking special lane respectively, width about 1.5 meters.In addition, at road, central authorities do not have tramway, just have two special roads that stop.Mon-Fri, from the morning 6 time 30 assign to late 7 time 30 points be the time that Parking permitted.At the restaurant, the place that bar is assembled, down time can be relatively longer, but generally also only allow same car to stop two hours in same position, two Australian Dollars one hour.Driver directly uses slot machine, pays parking fee, obtains parking fee receipt, under being pressed in windshield, then having managerial personnel and check receipt.If driver does not have consciously to pay parking fee, fine is 55 Australian Dollars.The market of office building, hospital and residential neighborhood has large-scale sky parking usually, and our unit personnel only need pay little expense, social personage then This vehicle stops frequently, length between expense apparent time and determining.
