Abstract

Two optical barriers (L1,L2) are sepd. by a distance (L) along a track inclined at an angle (theta) to the horizontal (H). The coin (M) rolling down the track starts a timing operation at the first barrier and terminates it at the second. From the durations of occultation at the two barriers and of transit between them, the length of a chord (B) of the rolling coin at a max. distance from its edge equal to the distance (h) of the barriers from the track is calculated on the assumption of approximately constant acceleration. <IMAGE>

Description

Išradimas priskiriamas autentiškumo tikrinimo būdams ir jame aprašytas monetų ar kitu plokščiu gaminiu autentiškumo tiktinimo būdas, apibūdintas apibrėžties 1 punkto įvadinėje dalyje.The invention relates to authentication methods and describes a coin or other flat article authentication method as described in the preamble of claim 1.

Tokie monetų tikrinimo būdai tinkami, pavyzdžiui, monetų identifikavimui telefonuose - automatuose, pardavimo automatuose, energijos matavimo skaitikliuose ir t.t.Such methods of checking coins are suitable, for example, for identifying coins in telephones - vending machines, vending machines, energy meters, etc.

Yra žinomas monetų testeris ir monetų tikrinimo būdas aprašytas FR patente Nr.1605182. Išilgai monetos kanalo yra įrengti du šviesos barjerai, laiko tarpas, per kuri moneta praeina nuo pirmojo šviesos barjero iki antrojo, ir laiko tarpas, kurį moneta dengia antrąjį šviesos barjerą, palyginamas su iš anksto nustatytomis reikšmėmis. Toks matavimas visiškai tiksliai parodo monetos stygos ilgi. Kad būtu galima išvengti skirtingu pradinių greičių, būtina rele sužadinama strektė, kuri sustabdo įmestą monetą ir vėliau atlaisvina kanalą jai.A known coin tester and a method for checking coins are described in FR Patent No. 1605182. Two light barriers are provided along the coin passage, the time it takes for the coin to pass from the first light barrier to the second and the time the coin covers the second light barrier against a predetermined value. Such a measurement gives the exact length of the coin strings. In order to avoid different initial speeds, a trigger is needed to relay the coin, which stops the coin thrown and subsequently releases the channel to it.

DE paraiškoje Nr.2015058 C2 aprašytas monetos testeris, turintis strektę, atlaisvinančią monetos kanalą, magnetą, sustabdantį monetą priklausomai nuo jos specifinių sąvybių, ir du šviesos barjerus, nustatančius monetos, praėjusios pro magnetą, greitį. Čia nėra jokių apsauginių priemonių, priimančių domėn monetos, judančios nuo pirmojo šviesos barjero link antrojo, pagreiti. Monetos detektavimo patikimumo padidinimui prieš stabdymo magnetą yra įrengti du papildomi šviesos barjerai, kurių dėka nustatomas monetos greitis prieš jai įeinant i magneto magnetini lauką.DE Application No. 20155058 C2 discloses a coin tester having a stroke that releases the coin channel, a magnet that stops the coin depending on its specific properties, and two light barriers that determine the velocity of the coin passing through the magnet. There are no safeguards here to accelerate the coin moving from the first light barrier to the second. To enhance the detection reliability of the coin, two additional light barriers are provided before the stop magnet, which allows the coin speed to be determined before it enters the magnetic field of the magnet.

Monetų testeris ir monetų testavimo būdas, nustatantis monetos skersmenį dviejų šviesos barjerų pagalba, yra žinomas iš EP paraiškos Nr,119936 Al. Moneta rieda išilgai kanalo ir per tam tikrą laiko tarpą įgauna pastovų pagreitį.The coin tester and the coin test method for determining the diameter of a coin by means of two light barriers are known from EP Application No. 119936 Al. The coin rolls along the channel and gains steady acceleration over a period of time.

Vidutinis greitis apskaičiuojamas pagal laiko tarpus, kuomet moneta dengia du šviesos barjerus, ir yra naudojamas pagreičio poveikio, nustatant skersmenį, patikslinimui.The average velocity is calculated from the time the coin covers two light barriers and is used to adjust the effect of acceleration in determining the diameter.

EP paraiškoje Nr.483451 Al naudojamas laiko tarpų, per kuriuos riedanti išilgai kanalo moneta dengia du šviesos barjerus, aritmetinis vidurkis, apibrėžiantis monetos stygos ilgįSiame išradime siūlomas monetos tikrinimo būdas, kuriuo testuojamos monetos stygos ilgis gali būti nustatytas paprastai ir tiksliai nepriklausomai nuo pradinių sąlygų.EP-A-483451 A1 uses the arithmetic mean of the time intervals between two light barriers rolling along a channel coin to determine the length of a coin string. The present invention provides a coin verification method that can determine the length of a coin being tested easily and accurately regardless of initial conditions.

Tai pasiekiama šiuo išradimu dėka sąvybių, išdėstytų apibrėžties 1 punkte.This is achieved by the present invention thanks to the features set forth in claim 1 of the definition.

Monetų testavimo būdas ir įtaisas tam būdui įgyvendinti yra detaliau paaiškintas žemiau pateiktu vieninteliu brėžiniu. Brėžinyje parodytas monetų, žetonų ar kitų plokščių gaminių autentiškumo testeris. Įtaisas turi monetos kanalą K, du šviesos barjerus L1 ir L2 ir elektronini prietaisą E, skirtą iš šviesos barjerų L1 ir L2 siunčiamų elektros signalų įrašymui ir įvertinimui. Srityje tarp monetos įėjimo ir pirmojo šviesos barjero L1 kanalas K turi energiją sugeriančius elementus, neleidžiančius monetai M šokinėti tarp dvieju šviesos barjerų L1 ir L2, o srityje tarp dviejų šviesos barjerų Ll ir L2 monetos kanalas K turi nuožulnios plokštumos SE. pasvirusios horizontalios plokštumos H atžvilaiu kampu Q, pavidalą. Nuožulnia plokštuma SE tarp dviejų šviesos barjerų L1 ir L2 moneta M juda žemyn pastoviu pagreičiu, kuri sukuria gravitacinės ir trinties jėgos. Moneta gali tik riedėti arba tik slysti arba ir riedėti ir slysti. Šviesos barjerai L1 ir L2 yra įrengtiThe method of testing the coins and the device for implementing the method are explained in more detail in the sole drawing below. The drawing shows an authenticity tester for coins, tokens or other flat products. The device has a coin channel K, two light barriers L1 and L2, and an electronic device E for recording and evaluating electrical signals transmitted from the light barriers L1 and L2. In the area between the coin entrance and the first light barrier L1, channel K has energy absorbing elements preventing the coin M from jumping between the two light barriers L1 and L2, and in the area between the two light barriers L1 and L2, coin channel K has a sloping plane SE. a reciprocal of the inclined horizontal plane H at an angle Q. The inclined plane SE between the two light barriers L1 and L2 moves downwards at constant acceleration, which produces gravitational and frictional forces. The coin can only roll or just slide or both roll and slide. Light barriers L1 and L2 are installed

SE iš anksto nustatytame virš nuožulnios plokštumos vienodame aukštyje h su iš anksto nustatytu tarpu L. Atstumas, kurį moneta M nueina plokštuma SE per laiką t, pažymėtas koordinate x(t). Koordinačių ašies x ir laiko t išeities taškai xo ir to yra parinkti taip, kad atitinkamai xo - O ir to -O, kuomet moneta M pradeda dengti pirmąjį šviesos barjerą Ll.SE at a predetermined plane inclined at equal height h with a predetermined gap L. The distance M coincides with the plane SE at time t is denoted by the coordinate x (t). The starting points xo and t of the coordinate axis x and time t are chosen such that xo - O and to - O, respectively, when the coin M begins to cover the first light barrier Ll.

Monetos M masė - m, spindulys - R ir inercijos momentas - I. Inercijos momentas I susijęs su sukimosi ašimi, praeinančia per monetos M svorio centrą. Kaip žinoma, vienalytės monetos I - l/2mR2. Lygiagrečios nuožulniai plokštumai SE ir esančios aukštyje h monetos M stygos ilgis lygus B. Monetos M svorio centras juda greičiu v(t). Moneta M sukasi apie savo svorio centrą kampiniu greičiu w(t). Monetos M energija susideda iš potencinės energijos Epot, svorio centro kinetinės energijos Ek i n ir sukimosi energijos Erot, priklausančios nuo jos svorio centro:The coin M has a mass m, radius R and a moment of inertia I. The moment of inertia I relates to the axis of rotation passing through the center of gravity of the coin M. As is known, the coinage is I - l / 2mR 2 . Parallel to the inclined plane SE and at height h, the length of the string M of the coin is B. The center of gravity of the coin M moves at velocity v (t). Coin M rotates about its center of gravity at an angular velocity w (t). The coin M energy consists of the potential energy Epot, the center of gravity kinetic energy Ek in and the rotational energy Erot, depending on its center of gravity:

E - Epot + Ek i n + Erot = = mg sinQlL + B - x) + l/2mv2 + l/2Iw2, (l) kur g reiškia svorio dėka įgaunamą, pagreitį.E - Epot + Ek in + Erot = = mg sinQlL + B - x) + l / 2mv 2 + l / 2Iw 2 , (l) where g represents the acceleration due to weight.

Kuomet to = O, monetos M greitis v - vo, o jos kampinis greitis w = wo, todėlWhen to = O, the coin M has velocity v - vo and its angular velocity w = wo, therefore

E(xo = O) = mg sinQlL + B) + l/2mvo2 + l/2Iwo2 (2).E (xo = O) = mg sinQlL + B) + l / 2mvo 2 + l / 2Iwo 2 (2).

Energijos tvarumo dėsnis iššaukia lygtįThe law of energy sustainability challenges the equation

Kuomet moneta M rieda kanalu. ji paeiliui dengia du šviesos barjerus LI ir L2. Momentas ti žymi pirmojo šviesos barjero LI dengimo pabaigą., momentas t2 - antrojo šviesos barjero L2 dengimo pradžią ir momentas t3 - antrojo šviesos barjero L2 dengimo pabaigą. Taip atsiranda sekančios lygtys (6), 17). 18)The coin M rolls up the channel. it covers in turn two light barriers LI and L2. The moment ti denotes the end of the coating of the first light barrier LI, the moment t2 represents the beginning of the coating of the second light barrier L2 and the moment t3 represents the end of the coating of the second light barrier L2. Thus follows the following equations (6), 17). 18)

Išsprendę šią lygčių 16), 17), 18) sistemą, gaunameBy solving this system of equations 16), 17), 18) we get

Formulė (9), nustatanti monetos M stygos ilgį B, neturi jokių sudedamųjų, priklausančių nuo jos pradinio greičio vo, pradinio kampinio greičio wo ar bet kokios fizikinės pastoviosios. Stygos ilgis apskaičiuojamas tik pagal iš anksto nustatytą tarpą L tarp dviejų šviesos barjerų LI ir L2 ir pagal matuojamus momentus ti, t2 ir t3 . kuomet laiko ašis nustatoma taip, kad to - O. Tuo būdu, momentai ti , t2 ir t3 žymi tik laiko skirtumus. Monetos M spindulys R gali būti apskaičiuotas pagal stygos ilgi B ir pagal aukštį h:Formula (9), which determines the length B of a coin M, has no component depending on its initial velocity vo, initial angular velocity wo, or any physical constant. The length of the string is calculated only from the predetermined gap L between the two light barriers LI and L2 and from the measured moments ti, t2 and t3. when the time axis is set so that - O. In this way, the moments ti, t2 and t3 denote only time differences. The radius R of a coin M can be calculated from the length B of the string and from the height h:

B2 + 4h2 B 2 + 4h 2

8h (11 )8h (11)

Momentos M pagreitis gali būti apskaičiuotas panašiai pagal momentus ti , t2 ir t3, naudojantis formule (10). Jei tarsime, kad moneta M rieda neslysdama, inercijos momento I santykis su monetos M mase m gali būti nustatytas pagal formules (4), (10) ir (11):The momentum M acceleration can be calculated similarly for moments ti, t2 and t3 using formula (10). If we assume that the coin M rolls without slipping, the ratio of the moment of inertia I to the mass m of the coin M can be determined by formulas (4), (10) and (11):

I gR2 sinQ .I gR 2 sinQ.

- = ---R2 (12).- = --- R 2 (12).

m aim ai

Jei moneta tik slysta, jos sukimosi energija išnyksta ir pastovus pagreitis a2 apskaičiuojamas taip:If the coin merely slides, its rotational energy disappears and the constant acceleration a2 is calculated as follows:

dv = -- = gsinQ d tdv = - = gsinQ d t

Integravus, gauname:When integrated, we get:

x(t) = l/2a2t2 + vo t = 1/2g sinQt=2 + vo t (13) .x (t) = l / 2a2t 2 + vo t = 1 / 2g sinQt = 2 + vo t (13).

(14)(14)

Kaip matyti, stygos ilgis B gali būti apskaičiuotas pagal formulę (9), žinant momentus ti, t2 ir t3. Formulė (9), pagal kurią nustatomas stygos ilgis B, gali būti pritaikyta ir tuomet, kuomet moneta M ir rieda, ir slysta, bet tik su ta sąlyga, kad jos svorio centro pagreitis beveik pastovus nuo momento to iki momento t3, t.y. kelyje tarp dviejų šviesos barjerų LI ir L2.As can be seen, the length B of the string can be calculated by formula (9), knowing the moments ti, t2 and t3. The formula (9) for determining the length of a string B can be applied even when the coin M is rolling and slipping, but only if its center of gravity acceleration is almost constant from moment to t3, i.e. on the road between the two light barriers LI and L2.

Momentai to, ti , t2 ir t3 turi būti tiksliai išmatuojami jau žinomais metodais. Pirmame monetų tikrinimo būdo variante signalai, kuriuos siunčia šviesos barjerai L1 ir L2, atskiromis linijomis yra perduodami į du mikroprocesoriaus Įėjimus, todėl gali būti nustatytas pageidaujamas tarpas L tarp dviejų šviesos barjerų L1 ir L2. Palankiausiame tikrinimo būdo variante tarpas L yra parenkamas didesnis nei didžiausios matuojamos monetos stygos ilgis B. Šiuo atveju, šviesos barjerai L1 ir L2 niekuomet neuždengiami kartu, todėl dviejų šviesos barjerų L1 ir L2 išėjimo signalai gali būti perduoti į bendrą mikroprocesoriaus Įėjimą. Kuomet moneta M praeina pro šviesos barjerus L1 ir L2, abiem atvejais po du impulsus paeiliui perduodama į mikroprocesorių. Pirmasis impulsas atžymi mikroprocesoriuje laiką to - O. Kiti trys impulsai nustato momentus ti , t? ir t3. Vėliau mikroprocesorius pagal formulę (9) apskaičiuoja monetos M stygos ilgi B, kuris yra kriterijus, apsprendžiantis, priimti ar išmesti monetą M.The moments ti, t2 and t3 must be accurately measured by known methods. In the first version of the coin screening method, the signals transmitted by the light barriers L1 and L2 are transmitted by separate lines to the two inputs of the microprocessor, so that the desired gap L between the two light barriers L1 and L2 can be set. In a preferred embodiment, the spacing L is selected greater than the length B of the largest coin being measured. As the coin M passes through the light barriers L1 and L2, in both cases, two pulses are successively transmitted to the microprocessor. The first pulse denotes the microprocessor time to - O. The other three pulses determine the moments ti, t? and t3. Subsequently, the microprocessor calculates the length B of the coin M according to formula (9), which is the criterion for deciding whether to accept or discard the coin M.

Tikslios formulės gali būti. žinoma, pakeistos apytikre formule, leidžiančia išvengti klaidu, kuomet skaičiavimai atliekami mikroprocesoriumi.Exact formulas can be. of course, replaced by an approximate formula to avoid errors when calculating with a microprocessor.

Aprašytojo tikrinimo būdo privalumas tas, kad nei monetos M pradinis greitis vo, nei pradinis kampinis greitis wo, nei pagreitis a neturi įtakos, nustatant stygos ilgį B, monetai M judant nuo pirmojo šviesos barjero link antrojo. Taip pat monetos kanale prieš pirmąjį šviesos barjerą L1 nereikalingas joks stabdymo, pavyzdžiui, magnetinis, įtaisas. Monetos M stygos ilgis B gali būti tiksliai tūkstantosios dalimi - nustatytas pagal formulę (9). Siūlomas tikrinimo būdas labiausiai tinka mašinoms, priimančioms įvairaus dydžio ir įvairių šalių monetas.The advantage of the method described is that the initial velocity vo, the initial angular velocity wo, and the acceleration a of the coin M are not influenced by the length of the string B when the coin M moves from the first light barrier to the second. Also, no stopping device, such as a magnetic one, is required in the coin channel before the first light barrier L1. The length B of the coin M can be exactly one-thousandth, as determined by formula (9). The proposed verification method is most suitable for machines accepting coins of different sizes and countries.

Monetos M inercijos momentas I priklauso nuo lydinio, iš kurio ji yra padaryta. Jei ją sudaro daugybė lydinių, inercijos momentas I tuomet priklauso ir nuo geometrinio lydiniu išdėstymo monetos M viduje. Inercijos momento santykis su mase I/m yra sekanti kokybė, charakterizuojanti monetą M. Jei moneta M riedėtų monetos kanalu neslysdama, santykis I/m galėtų būti naudojamas kaip tikslus monetos M priėmimo ar išmetimo kriterijus, ir nereikėtų indukcinio daviklio, nustatančio lydinio sudėti.The moment of inertia I of a coin M depends on the alloy from which it is made. If it is composed of many alloys, the moment of inertia I then depends on the geometric arrangement of the alloys inside the coin M. The ratio of the moment of inertia to the mass I / m is the following quality that characterizes a coin M. If the coin M scrolled through the coin channel without slipping, the I / m ratio could be used as an accurate acceptance or ejection criterion for coin M.

Prietaisas gali turėti kitus daviklius, skirtus kitų ypatybių - pavyzdžiui, monetos storio - matavimui, apsprendžiančių monetos M tinkamumą.The device may have other sensors for measuring other features, such as coin thickness, which determine the suitability of a coin M.
