Description

The implementation method of unmanned multilingual city tour-guide and interpretation system

Technical field

The present invention relates to utilize the current techique standard of existing mobile phone and audio frequency, the video data compression technology of computer, a unmanned guide and the method for interpretation system play in inner tissue on a large scale.It can provide multilingual service for the people that use different language, and this system's particular does slightly that change promptly can be the blind person and the deaf-mute provides service.It can be in the zonule independent use also can link and implant the operation of mobile phone universal network, for the user of different regions and country provides remote service.

Background technology

At present known relevant venue need be equipped with the announcer to separating of object and the geographical environment main manual type that adopts of guide of mediating a settlement, and tourist group need be equipped with guide of the group of accompanying and destination guide.Generally speaking, the visitor can only follow guide and announcer passively, can not select the own exhibit information that needs arbitrarily, can not be in the object group accept relevant information according to the order of oneself hope.Especially at high density object group's venue, announcer's sound even interfere with each other becomes noise.Tourist guide and announcer are subjected to the restriction of language or professional standards, and multilingual and high-caliber explanation can not be provided, and it will be more using the difficulty that the visitor ran into of rare foreign languages.At the venue that the Art Museum, library etc. need be mourned in silence, it is then difficult more that the visitor wants to obtain necessary information.

Existing most explanation equipment mostly is the special equipment of a certain specific venue, visual displaying as physical property explains orally plate, wired broadcasting or explanation earphone, electric horn, small-sized explanation machine (magnetic tape type, chip type), the small-sized interpretation system that short-distance wireless Mike that the announcer uses and reception earphone group become etc.Though these equipment are to a certain extent for the visitor provides convenience, information capacity is all extremely limited, and languages are single, and incompatible between the various device, can not be communicated with between each venue.For deaf-mute, blind person, more there are not off-the-shelf equipment and method to help them in strange occasion, to obtain needed information.

The technical solution adopted in the present invention is:

Purpose of the present invention and usefulness are, between the relevant information of user and various objects, set up the information flow link, overcome language obstacle, language performance obstacle, dysacousis and vision disorder etc. obtain object and geographical position for the user in sighting distance the difficulty that information requirement caused, make relevant expert not restrictedly served by languages and region for different crowd to the achievement in research in each field.

Maximum technological difficulties are, its size of object (objectives) in user's sighting distance may be very little, at a distance of very near again, for example have several showpieces (Fig. 2) on one meter exhibition booth far away of distance users, as want to know and must position one of them information (appointed), and send correct search instruction it, could from immense information bank, detect the corresponding informance (IOAO, information of appointed objectives) of this object as cigarette; The second, the user may be at random to its order (order) of the information requirement of object, and each user's demand order also is different, and for example a user's demand is BACD rather than ABCD in proper order, and another one user's demand may be again ACBD.

At present measurement in GPS or the mobile communication and retrieval technique can to move or static object position, but they all do not reach the requirement of above-mentioned two examples.This guide and interpretation system even may require higher positioning accuracy: the different piece to same object explains orally, for example, respectively the cap for brush of a pen and its position in information bank of information of penholder are retrieved the location, and provide corresponding informance (IOAO).Demand according to the user, determine object at random, and send corresponding search instruction (Scouting Order) to information bank, even the simple technical equipment G3 standard that relies on is not accomplished yet, promptly allow to accomplish and be that each object installs a wireless signal generator, use as locator, its high cost also is difficult to accept.

The invention of native system is to provide geographical environment in its visual range and object for information about for the user, so in system operation region or the object (1 that need explain orally for each part in the venue of zonule, 2) determine an identity code (3,4), and determine a corresponding code (5) for the corresponding informance of this object among the information database B, the two structure is identical, the homogeneity of the two is given this code with the 3rd identity, that is: the user retrieves the particular search instruction SO (Scouting Order) that corresponding informance sends in database, the connotation of corresponding informance code is three's synthesis and representative in compatible object identity code of SO and the database.The user determines object with visual method, in information database B, send the SO of this object by C with terminal, corresponding informance in the database promptly is recovered to voice messaging to compressed data information by operational network subsystem C, and user terminal can tell that the visitor sees is what, produce age, author, purposes, characteristics or the like.

Setting up the link of an appointed information and SO circulation in the object in reality (1,2), the same information bank of user (6) (14) between the corresponding informance of virtual state, is the basis of invention native system technical scheme.

For this reason, the present invention designs system to three subsystems that are mutually related:

A), target indication subsystem-target subsystem A is preceding half section of whole appointed information circulation link, promptly from object (1,2)-identity code direction board (3,4)-user terminal (6)-to user (27).

In entire city, determine a plurality of guide's points (1,25) and number sign indicating number according to actual needs outdoor for each guide puts one of regulation, the neighbour relation that all guides are ordered (Fig. 6-25) converts logical data to, deposit the database (14) of system in, the user is to the SO of terminal input starting point A and destination I, data processing centre (Fig. 1-11) is with being each guide's point code that the user provides may need process, and a plurality of codes promptly constitute the path A H-HI of starting point to the destination.Each guide's point has the tour guide speech of a correspondence, and the content of tour guide speech embodies progressive relationship, complements each other.Conclude all tour guide speeches and promptly can reflect the geographical overall picture of entire city, the visitor utilizes terminal in the hand while walking SO, and the analysis and judgement of listening to the audio guide speech of each point on the path one by one and adding oneself just can progressively arrive the destination according to leading of ordering of guide.

The guide puts number plate and adopts braille and on its next door Radio Beacon (Fig. 7-26) is set, the blind person presses the button of seeking of special-purpose terminal, hear the voice signal that Radio Beacon is sent, perhaps under the help of passerby's (even language obstacle), utilize the terminal and the braille code board of locking languages, the communicate information link obtains information more easily.At the less outdoor environment of object density, the interface that guide point also can use cost higher " bluetooth " standard provides more convenient service

Tour guide speech is play with the character message breath of various language, can satisfy the information requirement of the deaf-mute of various countries to object, obtains the guide service of native system.

Indoor or outdoor each object (2) is also stipulated an identity code, and make a code direction board (4) and be placed in object next door.The homographic solution excuse of each object, compression is made data message and is deposited information bank (14) usefulness fully in, each bar information is titled with the code (5) of a correspondence, the user with terminal (6) as indicated on the board identification number (4) of object dial and be SO, just can connect information bank and detect corresponding informance, (27) listen to relevant explanation.

Guide's point (1,25) and guide put coding (3); Object (2) and identity code (4) thereof are pressed different language (18), and different regions (16), zones of different is sorted out coding with different venues (17), promptly constitutes the target indication subsystem A of multilingual guide and interpretation system.

B), to set up information database subsystem-this subsystem B be the end of whole information flow link, its physical property structure is: mobile phone general-purpose interface (router one 0)-fire compartment wall (28)-maintenance and management center (12)-customer account management and charging center (13)-data processing centre (11)-information branch storehouse group (14).Hard disk and other storage mediums as stored information in this subsystem are parallel-connection structure.

After the compress technique that Voice ﹠ Video information is passed through MPEG (Moving Picture ExpertGroup) standard on computers converts numerical data and compression to, can flood tide storage on same hard disk.A memory can be stored song more than 1000 hours in the MP3 player, separate unit ordinary individual computer (its internal memory of market retail has reached 120G) also can be stored tens thousand of hours audio-frequency information as database, farther this level that surpasses of specialized database store video information data can satisfy the requirement to the data storage capacity of extensive guide and interpretation system fully.

Each guide is put the commentary of tour guide speech and object (certain position of a showpiece or this showpiece) and make voice messaging with the multilingual recording, each bar voice messaging length was approximately for 20 seconds to half a minute, and was recorded on audio tape or the CD dish with multilinguals such as the German-Chinese Japan and Russia of Great Britain and France respectively.Recorder can be connected on the PC, and the CD-ROM drive of computer can directly be read CD dish, the coding of ordering titled with corresponding guide in the front of each bar information or the identity code of object.

The manager of information bank downloads a MPEG working document from the Internet, the audio-frequency information conversion is compressed into the information data file of mpeg standard, these file branch languages are stored on a plurality of hard disks or other storage mediums, promptly can be made into voice (image) database of information subsystem B.The hacker that this manufacture method is general can both be grasped, and video information can be compressed equally and handle and storage, generally the equipment of playing compressed video file is called MP4, and the equipment of playing compacted voice file is called MP3.

When making compress informational data each languages (18) are generalized into a branch storehouse (Fig. 3) separately, the branch storehouse of each languages is respectively titled with separately languages code and be listed in the database subsystem of system.Languages can be used independent one or more hard-disc storage as a branch storehouse, also can be used as a subitem in the mass storage data storehouse.The structural relation in multilingual minute storehouse of information database is illustrated in figure 3 as coordination, its languages code of wherein Chinese C (Chinese) is 086, English E (English) is 001, French F (France) 003, and German G (Germany) 104 grades are respectively represented the branch storehouse of languages.

When object identity code (3,4) is represented with braille, the blind person helps to dial with the SO of the terminal dialing guide point of locking languages and object or passerby and cries, even language obstacle also can successfully obtain the guide and explain orally service each other.

Information data is stored in special minute storehouse with image (character message breath or sign language), and the deaf-mute dials the SO that is object, and what see on own terminal is the literal commentary.These writings and image information also can be used by other users.

The data structure of each bar information is that languages code (18)+area code (16)+venue (zonule) code (17)+explainative information (IOAO, IOC-19)+tail is sewed information (TA-21, Tail additions) and also be can be written as SO+IOAO or IOC+TA.

After the languages code is the ground field code in each province or city, supposes that Beijing is 010, Tianjin 022, Chongqing 029 etc.Be used for outdoor tour guide information and do not establish the zonule code after the ground field code, the visitor in being convenient to move uses.Suffix information is the image document of mediating a settlement of separating that gos deep into more, enriches.

The interface of information database B connects data processing centre (11), customer account management and charging center (13), and system operation and maintenance centre (12).Data processing centre controls the operation of this subsystem; Visitor's pipe, charging center are monitored and are counted system operation situation and get service fee, and the two hardware is the equipment of the mobile phone universal standard.OMC operation and maintenance centre can be replenished at any time to data of database, modification and renewal etc.

Another interface of information database B (through router 10) adopts G2 (the 2nd generation) the current techique standard of existing mobile phone GSM or CDMA, accepts service so that the various places user enters the native system network smoothly.According to the distinct communication standards of different regions, TD-SCDMA, ECDMA and the cdma2000 standard that adopts the G3 standard at a specified future date.

Information database B with storage hard disk (14) the same data processing of storage medium (11) of etc.ing of the guide of all guides' points and object in the total system zone of computer mpeg standard compression and explainative information, Operation and Maintenance (12), (13) three centers of management charging formation native systems.

C), operational network subsystem-this subsystem C adopts the universal standard and the equipment of mobile phone, is in the position in stage casing in the information flow link.The main hardware equipment that constitutes this segment has: user terminal MS (6)+base station transceiver BTS (7)+radio network controller (RNC) (8)+mobile services switching centre MSC (9) etc. constitute the little network of independence that the five internal organs are various, its linking objective subsystem A and information database subsystem B becomes in the zonule (venue) one independently guide and interpretation system.Interface (router one 0) can incorporate catenet to all business of native system as a professional subnet operation (Fig. 5), for the user provides remote service, realizes resource and information sharing.

Operational network subsystem C adopts the state-owned TD-SCDMA third generation standard configuration hardware device of international telecommunication connection approval, so that compatible forward present stage is adopted GSM, the CDMA standard of G2, G2.5.Audio frequency, the video transmission technologies of existing general G2.5 (the 2nd generation half mobile phone technology) standard are very ripe, and the mobile phone that data traffic the is huge business of seeing a film also puts into operation.Even adopt existing G2, G2.5 standard, also can satisfy the requirement of the extensive transmission of native system voice data fully.

After the user determines the identity code of object, import user terminal and send SO to information bank by the operational network subsystem, the corresponding informance that is detected is recovered to voice messaging through operational network C conversion and plays to user terminal, and the user can hear and specify object for information about.By the operation of three subsystems, set up the link of object to information flow between the information bank, guarantee that the interchange SO+IOAO between end user and the assigned object carries out on information specific circulation link.

Be closely connected between three subsystem A, B of native system, the C, indivisible.A is the material base of B, and B is the content of A, does not have any one of target indication subsystem or information database, guide and interpretation system just become nothing the resultant water without a source; Do not move subsystem, SO+IOAO has just lost passage, the huge storage capacity of computer technology is with the combination that can not be optimized of the abundant information resource of a large amount of venues and zonule, the user can only large quantities of manufacturing and is used little range of application, little information capacity, the small-sized commenting unit of single-piece, single venue special use more can't satisfy long-range auditory information demand, to information resources, material resources all is waste.

The MP3 player adds that numeric keypad and search program also can cooperate as the use of explanation machine with the target subsystem, but common index such as its information storage, the scope of application, economy all can't be compared with native system.

Embodiment

1, its guide's function of Fa Ming system can realize as follows:

Reach in the system operation region that bus station board (1), guideboard, billboard or landmark thing can be defined as guide's point one by one in the urban district, neighbour relation (Fig. 6) between guide's point converts logical data to and deposits database in, as long as the user is the SO of input A starting point and I destination, the information of same actual environment that terminal is received is compared, can determine own current position in the way, guide's point (25) will lead them while walking SO one by one, and pointwise arrives destination I point.Each guide puts the available self-adhesive paper of numbering and prints and stick on eye-catching place, pairing tour guide speech provides geographical position and the title that this guide is ordered, surrounding environment, go to information such as direction, the tour guide speech that interior thousands of the guides in serial connection zone are ordered has just constituted a complete wireless tour guide voice map.

For example shown in Figure 6, the visitor intends from the A point to the I point, the Lu Yousan bar in face of his, i.e. AB, AJ and AH.The SO input terminal that he orders A point and I, the data processing centre of system promptly issues the A point visitor's terminal to the shortcut AH-HI between I, the visitor knows that just next guide's point that he will look for should be the H point, after he has arrived the H point, import the SO that H orders again and listen to the audio guide that this guide is ordered, tour guide speech tells the visitor should select HI in HD, HJ, HI and four roads of HF, and the just very smooth arrival I of visitor point is taken an unnecessary way and needn't detour.

The deaf-mute can dial the SO that is object and connect one of them information bank of suitable own languages in the kinds of words information bank and obtain tour guide information.A mobile phone is installed is promptly can be used as the special-purpose guide of blind person and put use for the guide puts, when blind person (Fig. 7-29) is far away apart from guide's point (26) distance, the positioning function of mobile phone universal network can be accomplished the position of uninterrupted detection between the two, and the guiding blind person walks close to guide's point (Fig. 7-26).When walking close to guide's point, the blind person also can utilize the signal of seeking that special-purpose terminal is sent in the hand, start the Radio Beacon (26) that the guide is ordered, judge the position that the guide is ordered according to the sound that sends, put the braille code or SO under passerby's help by touching the guide, and listen to the detailed tour guide information of used languages, even he and passerby's language obstacle, by native system, he also can obtain detailed tour guide information.

2, its explanation function of Fa Ming system realizes as follows:

Each object in the system (1,2,25) has been prescribed code one by one, and respectively with a code direction board (3,4); The information of this object in information database is made of two parts equally, that is: the data code of information (the explanation tour guide speech data message (20+21) that Fig. 3-18+16+17+19)+compression is made, just SO+IOAO.Even in highdensity object group, target indication subsystem also can help the user to utilize code that the object in the sighting distance is accurately corresponding with the corresponding information in the database, set up correct information flow link, the user dials according to the number SO on the object identity direction board and is information bank, information that just can the uppick correspondence.

The length of each object (certain position of a showpiece or this showpiece) phonetic explaining speech was approximately for 20 seconds, what illustrate that the visitor sees is what, produces age, author, purposes, characteristics or the like, and be recorded in respectively on audio tape or CD (or VCD) dish with multilinguals such as the German-Chinese Japan and Russia of Great Britain and France respectively.Recorder can be connected on the PC, and the CD-ROM drive of computer can directly be read the CD dish, the manager of information bank downloads a MPEG working document from the Internet, just can easily the audio-frequency information conversion be compressed into the information data file of mpeg standard, these file branch languages are stored on a plurality of hard disks or other storage mediums, promptly can be made into voice (image) database of information subsystem, the hacker that this manufacture method is general can both be grasped.

Each languages all has a languages code (Fig. 3), supposes that Chinese is 086, English 001, German 104 etc.After the languages code is the ground field code in each province or city, supposes that Beijing is 010, Tianjin 022, Chongqing 029 etc.The data structure of each bar information can be expressed as longitudinally languages code (18)+ground field code (16)+venue (zonule code 17)+object identity code or the guide puts coding (19)+voice (image) information (20)+suffix information (image etc. 21), just languages code 18+SO+IOAO+TA.

As shown in Figure 3, divide in the storehouse in the Chinese languages of C (Chinese), the 086th, the code of these languages, the 010th, the code of Beijing, 456790 is the guide's coding on No. 1 automobile Xidan station board, so the code that this guide is ordered is 086 010 456790.Suppose that near certain the bronze ware museum code in Xidan is 131,34569 is the identity code of this bronze pot in shop, the complete identity code of this bronze pot is exactly area code+venue code (zonule code)+information identity code, i.e. 086 010 131 34569=086+SO.Thereafter be the explainative information of relevant this bronze tripod, suffix information is the image document of mediating a settlement of separating that gos deep into more, enriches.Thousands of such information stores just constitutes the information branch storehouse of these languages on hard disk.

The languages code, field code and venue code can be with self program locking of handheld terminal, for example, a user prepares to go to see this bronze pot, he can be locked in languages code 0086 and ground field code 010 in the hand-held user terminal in advance in order.Go to guide's point at 1 bus station, crossing, Xidan when him, as long as dial and cry 456790, can obtain about separating of area, the Xidan guide indication (IOC that mediates a settlement, Information Of City), be all numerals 086 010456790 and needn't dial, be not 086 010 these group numerals although the user dials, because it has been locked in lane terminal in advance, so still be launched away in 456790 front, SO can simplify.

Near he indicates according to the guide, comes bronze ware museum.The interpretation system in this museum is a small-sized autonomous system, its internal operation network disposes various device according to the universal standard of mobile phone, as: BTS (base station transceiver), RNC (radio network controller), MSC (mobile services switching centre), router or the like; The operation of voice messaging data of database processing center control system, OMC operation and maintenance centre and customer account management and charging center are searched for, are detected the demand that enters this system user, charging, broadcast etc.The venue in this shop is encoded to 131, the user uses terminal to need the code 131 in this shop of interim locking in the shop, can dial the identity code that is showpiece in the shop, he only needs to dial the identity code 3456 that is bronze pot, just can connect in the database explainative information (IOAO), be all numerals 086 010 131 3456 and needn't dial with this ancient cooking vessel correspondence.

In information database, the information data code of relevant this bronze pot is 010 131 3456 except languages code difference forever.Being 001-010 1313456 in the English database, is 104-010 131 3456 or the like in the German storehouse.010 131 3456 is about unique coding of corresponding informance in this bronze tripod and the information bank in the whole system.

Can also there be following embodiment in the system of this invention, as: this museum only connects operation (A+B+ macroreticular in the macroreticular of implanting mobile phone to whole information database B,), with the operation subsystem C of macroreticular alternative system, can avoid the fall overlapping investment of subsystem C of operation net.In such cases, this shop is that 131 group user identity is moved in macroreticular according to code.Three centers of information database B can be searched for, detect equally the demand that enters this database user, charging, broadcast etc., and its income is shared with macroreticular.

The native system (A+B+C) that connects the macroreticular operation (Fig. 5) of implanting mobile phone can also provide remote service, satisfy non-at-scene user's demand, the resource of database can be shared by user outside the system and can be used as the wireless remote voice dictionary and use.Arrive Tianjin 022 as the visitor and wanted to consult the more detailed data of this bronze tripod again, he just must dial the whole digital 010-131-3456 that cries except languages code and local code 022, as need particulars more, dial function key again and obtain the suffix information of bronze tripod information.

And for example, a user who says German needs the handheld terminal of oneself is at first locked with languages code 104, just can roam in system then, when he sees this ancient cooking vessel, if according to using notice to lock ground field code and venue code again, he only needs to dial to cry 3456 to get final product.After if he goes back to Germany (31), want to obtain the German information of this bronze tripod again, just must dial earlier and be toll number and nationality's number, and then group cry and to be positioned at whole digital 104 010,131 3456 of Beijing 010.

Information database C also can set up literal (image) branch storehouse.All store with the literal or the sign language of various language when all information, the deaf-mute of various countries can both obtain service more easily.

Interface of voice messaging database connects 3 centers of native system, i.e. data processing centre, customer account management and charging center and system operation and maintenance centre.The operation of data processing centre's control system, monitor system operation situation visitor's pipe, charging center, and meter is got service fee, and its hardware is the equipment of the mobile phone universal standard.OMC operation and maintenance centre can be replenished modification and renewal etc. at any time according to the mode of making voice messaging of mpeg standard to data of database.

Another interface adopts G2 (the 2nd generation) the current techique standard of existing mobile phone GSM or CDMA, so that database inserts its universal network operation smoothly.According to the distinct communication standards of different regions, TD-SCDMA, ECDMA and the cdma2000 standard that adopts the G3 standard at a specified future date.Behind the G3 standard implementation, can provide more free from worry operation passage for native system.

Another embodiment of its system of the present invention is: in the indoor use in showground of some restriction wireless radiation, control centre that can the slave unit room draws many signal line (Fig. 4-23) and connects the respective socket (22) that the showpiece next door is provided with and substitute object identity direction board, substitute the operational network subsystem with holding wire, the user can obtain appointed information equally with earphone (6) line socket.What this moment, the user used is lower-cost wired earphone special, and the chip of earphone is equipped with inspecting identity measuring program, accounting routine etc.Earphone is communicated with socket, and enabled instruction passes to exchange and data processing centre (Fig. 4-24) by holding wire, and relative programs such as detecting identification, information location, charging, broadcast is finished in operation maintenance center (12) and user management charging center (13).Except that wired socket, blue tooth interface, optoelectronic induction interface also can be used as one of selection mode that connects between object and the user terminal.This mini-system also can be reserved a wave point (10), so that be connected with macroreticular.
