Description
The present invention relates to a kind of game or game chip sheet or token that has the integrated electronic data carrier, and the device that is used to verify this chip sheet, equipment with using this chip sheet and check device also is useful in game station an initialized method of chip sheet.A sixty-four dollar question when using the chip sheet in the game machine of any kind is to prevent abuse and forgery.Along with game machine and game equipment come into operation increasingly extensively, the requirement that strengthens precaution becomes more important and urgent.Also requirement can be more rationally and is carried out more operating function reliably, such as the discriminating and the verification of chip sheet, exchanges, automatically classification or the like.
Existing document has disclosed some imaginations that increase the game machine precaution and improve chip sheet processing power.For example, disclose a kind of device that is used on game table the classification of chip sheet among the EP424355, this device utilizes optical color identification and reading head, for example utilizes ccd sensor, determine the face amount of chip sheet according to the color of chip sheet, so can automatically the chip sheet be classified.Disclose a kind of method and apparatus that is used for the classification of chip sheet among the GB2174228, conduction or magnetic material that this method utilization is inserted in the chip sheet produce an inductance or capacitance signal in sorter, and utilize these signals of sensor measurement.But, use this class chip sheet and sorter to carry out rough differentiation to the face amount of chip sheet.Therefore, can't verify out the chip sheet of forgery.Because all these chip sheets are easy to duplicate comparatively speaking, thereby forge easily,, can not provide enough precautions so other chip sheet recognition device for example adopts laser to read the device of magnetic stripe or bar code.In addition, these check methods are normally complicated, unreliable and be subjected to the influence of environment easily, the identification medium of for example making dirty and wear and tear.
Another kind of scheme proposes in EP436497, discloses in this patented claim a kind ofly to be used to play or thermoplastic production technology game device, that have or do not have the circular chip sheet of integrated reception-emission dual component.Can not contact in the reception-emission dual component of launching code information pattern a kind of more desirable reception-emission dual component is arranged, it has two kinds of dissimilar antennas, just a kind of electrostatic antenna and a kind of magnetic antenna, detailed content can be referring to US4818855.This makes and might read a chip sheet and verify the face amount of chip sheet in the noncontact mode in game machine.But, this need in game machine or Slot Machine, make the chip sheet with respect to readout device relatively near and accurately the location, promptly its location must be accurate to several millimeters magnitude.This known chip sheet that has reception-emission dual component is owing to comprise the recording medium element, plastic hoop, and different antennas, discrete reception-emission dual component, interface unit or the like is so thereby have a structure of relative complex, multi-part costliness.In addition, this structure only is suitable for filling in the circular token in the Slot Machine, and is not suitable for other sizes, shape and purposes, for example is used for the token in parking lot, and the square chip sheet that is used for desktop game and has higher face amount.Have difformity in order can in different game machines, to discern widely and to verify, any one chip sheet of size and face amount, must have bigger transmission scope, for example, several centimetres at least, rather than several millimeters.In addition, transmit content, make duplicate, forge chip sheet (magneto-band effect) thereby produce, so these existing chip sheets can not be really false proof because existing chip sheet still can surreptitiously be recorded its data.This method can not be produced the false proof chip sheet with higher face amount.Another big shortcoming is for the chip sheet that has reception-emission dual component, needs a central computer system, has the database that is used to verify all chip sheets in this system.Under the situation that central computer system breaks down, whole sports ground work will be interrupted, and this should not take place.This another limitation that has the chip sheet of reception-emission dual component is that its face amount can not change, and promptly can not reset.This has hindered the vicissitudinous recreation of object for appreciation price, and promptly those chip sheet face amounts can be fixed on the recreation of several different class.Therefore, forge difficulty more although this existing chip sheet makes, it still can not accomplish false proof, particularly has the chip sheet of higher face amount.
So problem of the present invention provides a kind of chip sheet, it has rationally simple structure, though low face amount chip sheet needs some energy when using, it provides outstanding false proof protection can for high face amount chip sheet.In addition, this chip sheet must generally be applicable to all recreation that can play in the recreation ground, thereby makes the business of whole recreation ground use the false proof chip sheet of this height to carry out.Therefore, chip sheet of the present invention must be applicable to all shape, structure and face amounts easily, must can verify in certain distance, must carry out simple and reasonably processing in corresponding verification and sorter.It also must verify the chip sheet in the mode of disperseing to carry out in corresponding check device, and need not be connected to a central computer, to guarantee higher operation precaution, not impaired thereby the business of whole recreation ground can not break down owing to a table apparatus is accidental, and fixedly face amount and not fixedly the chip sheet of face amount all be available.
This problem is solved by chip sheet as claimed in claim 1.Use this result to be, can guarantee from the hardware not reproducible, promptly copy this chip sheet with chip chip architecture of the height integrated data recording medium that wherein records not reproducible raw data.Data carrier will carry out initialization by an affirmation system, and this is necessary for its availability, can prevent to use unidentified chip sheet.Carry out the data transmission with the initialization data that keeps renewal and combine always and can guarantee that data transmit content and can not write down or be sent to (magneto-band effect) on other data carriers by duplicating with the password of stationary storage.By in conjunction with these features of the present invention, can realize maximum false proof defencive function with simple relatively method.It is simple having only the structure of an antenna for all functions, and allows antenna to have relatively large antenna surface area in the environment around, can see through electromagnetic shell, thereby can obtain relatively large data transmitting range.Corresponding discrete read-write equipment does not need to be connected with a main control computer, just can work automatically reliably.In addition, owing to can on data carrier, write data, so can change the face amount of chip sheet when being necessary.Therefore, according to the feature of chip sheet of the present invention, and in conjunction with relevant discrete read-write equipment WR, just can realize check device as claimed in claim 15 and sorter as claimed in claim 17, they satisfy requirement said, maximum precaution.Guaranteed in game playing system, to use by the method for a grade authoring system initialization chip sheet without data carrier MI or the chip sheet confirmed or forge.
Dependent claims relates to the useful improvement of the present invention, to realize the long especially operating distance of relatively large surface area antenna.By highly integrated on a printed circuit board (PCB) and use eeprom memory and ASIC circuit, can produce chip sheet compact, effective and with low cost especially.By utilizing RF (radio frequency) signal transmission of power and information simultaneously, can realize that special active data transmits, and in one direction by carrying out the duration of pulse modulation and load (load) modulation on another direction to come transmission information, this is useful especially.Other protection aspects can be by adopt the random digit that keeps renewal and verify the total value controlled quentity controlled variable by combination and realize always.As described in claim 19, a whole set of playground equipment can be provided, wherein different chip sheets can be handled by many corresponding automatic discrete read-write equipment WR, these read-write equipments are worked in fully automatic mode, and can be connected with a central computer system in addition, the latter can carry out other function and calculating.Therefore, the business of recreation ground can be owing to the random failure or the mistake of central processing system are interrupted.Discrete read-write equipment has guaranteed the game process continuously with unrestricted, and this is the requirement of particular importance.
Hereinafter the present invention is described in further detail with reference to example and accompanying drawing, wherein:

Figure 13 represents the production that has data carrier MI that can not copy.
Game or game chip sheet or token 1 that Fig. 1 has schematically shown is of the present invention, have integrating passive data carrier MI, its work capacity are to receive by read-write equipment WR emission and by means of a radio-frequency antenna 15.Data carrier MI is made of a highly integrated special-purpose chip sheet (ASIC), and this chip sheet comprises 11, one data storeies 12 of a processor (for example, an EEPROM form), and control circuit 13.The control circuit that has processor is controlled the exchange of all external datas and internal data, with the transmission digital coding with the data decode that receives, and comprise whole radio frequency generator spare, wherein comprise the clock preparation and the synchronous device that are used for from conveyer WR received energy and data to antenna 15 power supplies.
Fig. 2 schematically shows one and is used for transmitting data and related with it automatic discrete global function read-write equipment WR with 1 noncontact of chip sheet.This read-write equipment has 25, one emissions that separate of a protection module and 24, one power supplys of receiving antenna and a satellite interface that is connected usefulness with principal computer 65.Protection module 25 comprises the data transport functions between the data carrier of all and chip sheet.Comprising transmitting the radio frequency preparation that possesses for correctly carrying out data, establishment password and verification data (CRC) are confirmed to check to the read-write of special-purpose chip sheet by read-write equipment, and carry out data with principal computer and transmit.Safeguard function comprises the Code And Decode 22,23 of data, and the mandate that writes is checked in the identification of data carrier MI, and calculates and monitoring inspection and (CRC) operation, transmits to carry out data with being free from mistakes.Data mode between data carrier MI and the read-write equipment WR will be illustrated with reference to Fig. 6 hereinafter.
Fig. 3 a and Fig. 3 b represent a data recording medium MI, the structure of the chip sheet 1 of an antenna 15 and an auxiliary capacitor 17 of having of the present invention from two view directions.These elements preferably have the structure of one,, data carrier MI and auxiliary capacitor and antenna are produced on for this reason, for example, on the printed circuit board (PCB) 16.As can see from Figure 3, antenna surface area can be done very greatly.From the principle, in fact whole chip sheet surface can be as antenna surface.The both sides of antenna 15 are wrapped in by a housing parts 2 that can allow electromagnetic wave penetrate.In chip sheet of the present invention, only need a radio-frequency antenna, and can realize all functions, i.e. received energy and information, and information is transmitted among the read-write equipment WR.Therefore, this antenna can have a relative optional structure, particularly can have a bigger surface area, says on the principle and can use whole chip sheet surface.This has formed two conclusive features, that is to say, owing to the antenna that large surface area is arranged has big operating distance W from several centimetres to several decimeters, and can carry out the big space angle scope W that data transmit, and do not rely on the relative position of chip sheet 1 and relevant read-write equipment WR substantially.
The prior art of putting down in writing among this and the EP436497 is diverse, in the prior art, employed reception-emission dual component has two antennas, i.e. an electrostatic antenna and a magnetic antenna, they all need relatively and its counterpart very accurately and is closely located with the magnitude of millimeter, transmit to carry out data.This is possible in Slot Machine, because that Slot Machine only need read is circular, rotational symmetric chip sheet and have specific dimensions and be in the antenna of exact position, therefore two antennas all must accurately and very closely be provided with in this case.But this known reception-emission dual component and antenna structure can not be applicable to other chip sheets with difformity and size, particularly can not be applicable to desktop game.
The chip plate shape that Fig. 4 a expresses possibility to Fig. 4 f, as annular, circle, rectangle and polygon, and some examples with different antennae pattern 15.Always an antenna 15 with relatively large area might be integrated in the chip sheet, to obtain bigger data transmitting range.Shown in Fig. 4 a and Fig. 4 b, the chip plate shape be the minimum diameter DA of antenna under the rectangular situation or DA1 more preferably, be at least half size of chip sheet minimum diameter DJ or DJ1.Minimum diameter DA, the DA1 of antenna is more desirable is 20mm at least.Fig. 4 c represents that this surface is covered with by antenna loop 15 with respect to the antenna surface FA of chip sheet surface FJ.Antenna surface FA preferably is at least half size of chip sheet surface FJ.
Fig. 5 represents the read-write equipment of a protection module 25 and the communication 20 between data recording medium MI or the chip sheet 1.Needed electromagnetic radio frequency field energy 20a (for example carrier frequency is 13MHz) is transmitted into this data carrier MI from this read-write equipment WR with the information 20b through ovennodulation, said field energy is received by antenna 15 in this medium, and is used for driving and should passive data carrier MI works and coded message 20b is sent back among the WR.The special reasonable method that information data transmits is modulated carrier frequency in a direction, for example carry out pulsed modulation in the direction from read-write equipment WR to data carrier MI, is then loading (Load) modulation from MI to the WR reverse direction.
Fig. 6 is illustrated in the order that can not interrupt that data transmit between this read-write equipment WR and the data recording medium MI.Need only the applied field scope that data recording medium MI enters read-write equipment WR, begin to be used to make the order of WR and MI synchronous working automatically.Produce a new initialization data 21 form of random digit (for example with) for each new identifying read-write equipment WR, and this initialization data is sent among the data carrier MI (20.1).There is certain relation in the password 22 of fixed storage in wherein said initialization data 21 and the data carrier.Then, the result of coding (password) is transferred back to read-write equipment (20.2).This information is untied password in read-write equipment, and verifies (23) in protection module (25), promptly decodes with the coding (22) that is stored among the WR, and compares (21) with original primary data at random.On the basis of this comparative result, it is the data carrier of what type that WR can discern related.Interruptedly between read-write equipment WR and data carrier MI, do not carry out synchronous communication (20.3) with that.
In this method, the clock generator of WR and MI and code generator are synchronous workings.If data transfer procedure finishes or is interrupted, then new data convey program must adopt new initialization data 21 to restart.The data that transmitted of record, and order to import once more in this scope be impossible because original initialization data 21 is no longer valid.So can accomplish to make the chip sheet false proof.
In addition, utilize a CRC program, promptly utilize one to check and control program, verify the data that transmitted, the raw data among wherein useful data and the data carrier MI is linked.So having prevented wrong data transmits.This is a particular importance, if the face amount that is changed by an authorized read-write equipment is written among the data carrier MI, then the data of this new input will be through verifying before coming into force.According to this chip sheet transmitted data sequence of the present invention, can guarantee not exist abuse to interrupt data and transmit the possibility of forging the chip sheet to make.
Fig. 7 represents a check device 30, comprising discrete, a read-write equipment WR and a device that separates 35 automatically, any one chip sheet 1 of putting into is separated one by one in device 35, detect each chip sheet then respectively, and read and verify data simultaneously by this read-write equipment.Be placed in following three classifications one according to these chip sheets as a result of verifying: true chip sheet (31), forge chip sheet (32) or do not have the chip sheet (33) of identification response.For false proof, can verify once more the chip sheet of listing in classification 32 and 33, just can determine that whether it be one and forge chip, or have the people to attempt deception, or the fault of data carrier MI in the chip sheet, thereby take appropriate measures.Importantly obtain bigger data transmitting range R (referring to Fig. 3 a), the antenna 15 of the interior chip 1 of this distance and 24 with read-write equipment WR between can carry out reliable data and transmit, this distance can be several decimetres, for example 20 arrives 80cm.
Another important function is realized by the apparatus for automatically sorting among Fig. 8 40.At first the chip sheet according to the some that will not add the dissimilar and different denominations put into of ordering shown in Fig. 7 (35) distinguishes, and is verified by a read-write equipment WR, and the chip sheet of any forgery (32,33) is detected and is separated.Genuine then chip sheet (31) is sent to a sorter 45, and each chip sheet is placed on according to its predetermined face amount in the corresponding chip sheet heap 46.1,46.2 and 46.3 there.This device 40 can be rapidly be classified with the chip sheet that will have different denominations and shape automatically, thus can, for example on table for game with the unbroken recreation that circulates of big chip sheet.
Fig. 9 represents a face amount modifier 50, it comprises that a discrete device 35 can change special-purpose read-write equipment WR relevant, special-purpose chip sheet face amount with one, change in order to carry out face amount, it also is programmable, for this reason, it has a variable face amount storer 12.3, and this storer can be by writing a variable face amount through the face amount modifier 50 of authorizing.
Have clear determine, chip sheet visible and fixedly face amount although mainly be to use in recreation, yet need to use the chip sheet with variable face amount, it has tangible advantage, can be applicable to many other application.
1, the fixing chip sheet of face amount must keep same face amount in recreation ground the business hours fully, can verify it when returning the exchange platform, and its face amount is set to zero for preservation afterwards, and only is set to fixedly face amount when coming into operation once more.Therefore, these fixedly the chip sheet of face amount just in the normal game process, just need their effective face amount, and beyond playtime, be invalid, so be nugatory.So, theft, for example from safety cabinet, the chip sheet that this class face amount had lost efficacy is exactly nonsensical from the outset.
2, Another application is in the recreation that face amount changes, wherein, for example a kind of chip sheet of color is assigned to the people that each participates in game, and he can determine the face amount of its special-purpose color chip sheet himself, even gives the chip sheet for each new game and determine a new face amount.This face amount (1.0,1.1,1.2,1.3) can correspondingly be re-entered in the face amount storer 12.3 of chip sheet by face amount modifier 50.
3, Another application relates to as the chip that valency token thing or card are arranged, wherein write down certain amount of money, can (65, the amount of money of overdrawing in Figure 11) be zero, to obtain various services at the consumption point value that allows, these service content comprise in recreation ground, restaurant for example, bar, kiosk, the shop, beauty treatment room or the like.
4, another kind of modification utilizes special-purpose face amount modifier 50 constantly stake to be debted in said account's chip sheet face amount storer 12.3 as use " account's chip sheet " in band stake Game Zone 66, and the money that wins is credited.The condition that enters such band stake Game Zone 66 (Figure 11) is the enough amount of money that has at least on the credit entry of face amount storer 12.3 corresponding to stake.Advantageously for face amount storer 12.3 License Value scopes, only on the occasion of, be scheduled to, promptly do not allow and exceed a certain given peaked debt.
Say that in principle the face amount of chip sheet possible maximal value high more or in variable face amount storer 12.3 is high more, require also just high more for the strick precaution of forging and swindle is attempted.
But most of chip sheets have low face amount.The chip sheet that great majority recycle is minimum face amount class, for example is used for the chip sheet of Slot Machine.A major issue related to the present invention is to create the chip chip system of a novelty, adopt this system that the chip sheet of all types and various face amounts can be provided in various application, thereby be widely used for all recreation grounds, the chip sheet of minimum face amount can quite easily and be made cheaply, so that their manufacturing cost is lower than minimum chip sheet face amount, but can also satisfy simultaneously and the same high false proof requirement of false proof chip sheet of producing the highest face amount class.Chip sheet of the present invention makes this become possibility for the first time.
Therefore, might produce the chip sheet 1a of low face amount class and the chip sheet 1b of higher face amount class according to same principle, the chip sheet 1b of higher face amount has increased a bigger storer, additional more complicated coding, bigger antenna or the like.By means of relevant, and the read-write equipment WR that has carried out corresponding programming can more carefully monitor these big face amount chip sheets, thereby more strengthened false proof protection.
The game equipment 60 that Figure 10 represents to use chip sheet 1 and has many automatic central read-write equipment WR, said read-write equipment is used for different functions, promptly be used for check device 30.1,30.2,30.3, sorter 40.1,40.2,40.3, with face amount modifier 50.1,50.2, comprise record keeping device 55.Except their discrete function, these devices or read-write equipment WR also link to each other with principal computer 75.This makes them can carry out other programs of input, to detect the function of the operational data of read-write equipment WR that assessment is different with further processing and used chip sheet 1.
According to Figure 11, these functional devices 30,40,50 are used on the different location of recreation ground 60, for example, exchange platform 61 at inlet, and chip sheet and coin are cashed platform 62, table for game 63, the various consumption place of Slot Machine 64 and usage billing device 55.As an example, here explain the chip sheet that can use two kinds of different class, promptly on Slot Machine 64, use low face amount chip sheet 1a, on the table for game 63 that is provided with high stake, use the chip sheet 1b of higher face amount, use account card chip sheet 1c in each consumption place 65 with in band stake Game Zone 66.This shows chip sheet 1 of the present invention again, 1a, and 1b, 1c can be widely used for recreation ground and game equipment, and this utilizes present known chip sheet not accomplish.
Figure 12 a represents grade mandate summary A, and this is for all data carrier MI and all read-write equipment WR, and the programmer WRI of all authorization data recording medium AMI and system is effective, it has architecture class or rank (OL0, OL1, OL2, OL3, OL4, or the like.The highest class, structure rank OL0, corresponding to system's class, i.e. whole owner 10 of systems.Next lower class OL1 is corresponding to different, and independently the user of system 101,102,103, for example different recreation ground companies.Next more low-grade OL2 is corresponding to the different application 101.1,101.2 of user 101, for example different recreation grounds of company 101.Next class OL3 is corresponding to the zones of different of using, the zone 101.21 and 101.22 of the zone 101.11 of recreation ground 101.1 and recreation ground 101.2 for example, and for example with the different device in a recreation ground, the zones of different that type of play embodies.Next class OL4 corresponding to different subregion 101.21,101.22 (=OL3), 101.211,101.221 (in OL4) or the like for example.
This grade authoring system has guaranteed not phase mutual interference by any way of different user 101,102,103, but a concrete user, and for example 101 can as from the OL2 rank, freely determine its structure in his zone.Therefore, authoring system A must remain on rank OL1 at least.This is by 70 expressions of a dividing line among Figure 12.This also guarantees from this side any abuse to be arranged, and for example, uses the phenomenon of the chip sheet of other recreation ground company to take place (because 101 chip sheet generally is not allow to be used in 102 and 103).
In this authoring system, each the downward ladder of a structure rank in from OLn to OLn+1, the right of data carrier all is carried out restriction, thus it can only use downwards, promptly corresponding to the structure rank of bigger numerical.Shown in Figure 12 b, for this purpose, other data that before write of all higher structural levels all must write among a certain other data carrier of ad hoc structure level MI, promptly seem to have been inherited.Write in a fixed manner in storer 12 in the additional memory portion for each lower structure rank OLn+1, the data of all higher structure rank OLn all are received simultaneously.Therefore, in turn, for example 10,101,101.1,101.11 be written into structure rank OL0, OL1 is among OL2 and the OL3.
This principle shows clearlyer in Figure 13, the figure shows the production or the initialization of the chip sheet with data carrier MI.All data carriers of system must utilize an original record medium 71 (as authorization data recording medium AMI) and a special-purpose programming read-write equipment WRI to produce as a subordinate recording medium 72.The one group of master data that can not wipe in the original data record medium 71 also must be added and is sent on the subordinate recording medium 72, i.e. succession or seal people are in a data carrier MI who does not write personal data new, system.This is to carry out according to the principle of grade authoring system A.The data carrier MI that is produced (as subordinate data carrier 72) is initialized as authorization data recording medium AMI by original record medium 71.This initialization procedure is to allow to use this data carrier, thereby uses the condition precedent of chip sheet 1 in system.Have only through initialized data carrier MI and thought effectively by system read-write device WR.
Utilize the getable maximum strick precaution ability of chip sheet of the present invention to be summarized as follows:
Each chip sheet that has a data carrier comprises fixing, programmable, not reproducible and a unreadable program that has encryption algorithm, and not reproducible, inalterable raw data with unique numerical value.
Data carrier MI can not be replicated, and it is impossible all data being copied to another from the data recording medium, and therefore imitated data carrier also is impossible.
To send data be unreadable by one and cryptographic algorithm that can not copy is protected to data carrier MI from read-write equipment WR.
Because all produce a new random digit sequence for identifying each time, thus the data that record transmits, and then to provide be impossible.
Owing to transmit wrongly by checking and control CRC detects, and the data of new input all will have affirmation, so the consistance of data is reliable.
The grade authoring system has guaranteed that the different users of system can not influence each other.
Therefore, constituted the chip sheet that a kind of anti-counterfeiting performance is stronger, production cost is lower, it can be widely used in all types of game equipment, and guarantees its operation failsafe.
