Mobile phone speech based on server end speech recognition enters for charging system and method thereof
Technical field
The invention belongs to parking lot technical field, especially a kind of mobile phone parking charging system and method thereof based on server end speech recognition.
Background technology
At present, the stopping charging system of binding parking space detector is a kind of common system, it is advantageous that and utilizes parking space detector automatically to calculate parking duration.This stopping charging system, in Car park payment processing procedure, need to solve following problem: by Parking Stall number and parking space detector bind, by Parking Stall number with car owner's identity is bound, car owner's identity and car owner's account number are bound.Wherein, the method of Parking Stall number and car owner's identity binding can adopt the method for label binding, also can adopt the method for handset binding, vahicles label is installed in label binding exactly, vahicles label contains car owner's identity unique ID number, and in the time that car owner is stopped, label is identified by parking space detector and by parking space detector, No. ID, label, car item is together uploaded to server, the problem that the method exists is: need to install in addition vahicles label, strengthen construction cost.The method of utilizing mobile phone that Parking Stall number and car owner's identity are bound generally has 3 kinds of modes: first kind of way is on mobile phone, to input car item, and the problem of its existence is: error easily appears in manual input; The second way is in advance by the binding of cell-phone number and license plate number, then by license plate number and the binding of car item, the method because of many one by the link of license plate number and the binding of car item, increased handling cost; The third mode is to use mobile phone photograph car item, although the method is quick, shooting angle and luminosity often affect the quality of shooting.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of reasonable in design, accurately and reliably and quick mobile phone parking charging system and method thereof based on server end speech recognition easily.
The present invention solves existing technical matters and takes following technical scheme to realize:
A kind of mobile phone speech based on server end speech recognition enters for charging system, comprise mobile phone, parking space detector, radio network gateway and server with voice dispensing device, described server comprises mobile background server and coupled parking lot background server; The described mobile phone with voice dispensing device is connected with mobile background server by radio network gateway and sends parking stall speech data, and described parking space detector is arranged on below parking position and by radio network gateway and is connected with parking lot background server; The parking space state information that the car item speech data that described parking lot background server transmits mobile background server and parking space detector transmit is processed and is realized the quick charging function in parking lot.
And described radio network gateway comprises that mobile system base station gateway and parking position detect information collector.
And described parking lot background server comprises that the voice recognition server, the parking position that link together by network detect server and parking fee collective system server.
And described parking lot background server is the parking lot background server that integrates sound identifying function, parking position measuring ability and parking fee collective system function.
And described voice recognition server comprises server end acoustic recognition unit and server end voice recognition dictionary.
Mobile phone parking payment methods based on server end speech recognition, comprise the following steps:
Step 1, on the background server of parking lot, set up voice recognition server and server end voice recognition dictionary;
Step 2, parking stall measure server are bound car owner's cell-phone number and car owner's payment account, and parking space detector and current car item are bound;
Step 3, car owner enter for car item speech data, the cell-phone number of current paying to mobile background server by the mobile phone with voice dispensing device;
Step 4, parking lot background server receive car item speech data by mobile background server, and voice recognition server is identified as voice document car item and recognition result and the whether successful identification information of identification are sent to mobile background server.
Step 5, mobile background server are confirmed car item with the mobile phone interaction with voice dispensing device;
Whether successfully step 6, parking stall measure server obtain car item and identification identification information by mobile background server, and the parking duration of this parking stall of parking space state change calculations of uploading according to the successful car item of identification and parking space detector corresponding to this car item;
Step 7, Car park payment server carry out backstage parking according to car item, the payment accounts of this cell-phone number binding and deduct fees.
And the process that described step 1 is set up server end voice recognition dictionary is:
(1) voice recognition server is collected and sets up take parking lot magnanimity voice and the language database as each parking position of classification number;
(2) the magnanimity voice of voice recognition server to each parking position of collecting number and language database is processed and knowledge excavation, obtain acoustic model and the language model of the required car item of speech recognition, thereby set up the server end voice recognition dictionary that comprises car item.
And the method that described step 4 is identified as car item by voice recognition server by voice document is:
(1) voice recognition server receives car item speech data by mobile background server;
(2) acoustic recognition unit of voice recognition server is compared the stored vocabulary in voice recognition dictionary unit of the sounding geodata and services device end of reception, if identified successfully, server end is identified to successful identification information and recognition result and sent to mobile background server; If identify unsuccessfully, unsuccessful identification information is sent to mobile background server.
Advantage of the present invention and good effect are:
The present invention sets up Car park payment voice recognition dictionary and sound identifying function at parking lot background server, by voice recognition server, user's real-time voice is carried out to on-line automatic identification, by the parking duration of this parking stall of the real-time parking space state change calculations of parking space detector, car item by Car park payment server to cell-phone number binding, payment accounts is carried out backstage parking and is deducted fees, this is the most natural to utilize " voice ", means are carried out man-machine communication and are realized alternately the quick payment function in parking lot the most easily, solve dexterously the bottleneck problem of the quick charge in parking lot for a long time.
