Spôsob brzdenia a/alebo zastavenia koľajového vozidla a zariadenie na jeho vykonávanieMethod of braking and / or stopping the rolling stock and apparatus for carrying it out
Oblasť technikyTechnical field
Vynález sa týka spôsobu brzdenia a/alebo zastavenia vozidla železnidného typu pohybujúceho sa na koľaji a zariadenia na vykonávanie tohto spôsobu.The invention relates to a method of braking and / or stopping a rail-type vehicle moving on a track and an apparatus for carrying out the method.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Prevádzka železničných súprav je tradiCne riadená signálmi rozmiestenými pozdĺž železničných trati. Za vykonávanie príkazov signalizačných zariadení zodpovedá strojvodca, ktorý Často sleduje signály pri nepriaznivých vonkajších podmienkach, napr. v hmle, pri Bnežení, ostrom slnečnom svite.The operation of railway trains is traditionally controlled by signals distributed along the railway lines. It is the responsibility of the driver to execute the signaling device commands, which often monitors the signals under adverse external conditions, e.g. in the fog, at Snowfall, in sharp sunlight.
Je známe, že strojvodca má k dispozícii technické prostriedky na kontrolu rýchlosti vozidla. Sú to systémy, ktoré sú pevne zabudované na urCených známych úsekoch pozdĺž železničných tratí. Vozidlo je opatrené prijímacou anténou, ktorá detekuje jeho prechod nad prvým systémom, súCasne sa zapína Časomiera, ktorá sa vyprie pri prechode nad nasledujúcim systémom. Pretože je známa vzdialenosť medzi oboma systémami a Cas, za ktorý vozidlo prešlo túto vzdialenosť, je ľahké vypočítať jeho rýchlosť. Je však treba poznamenať, že ide o priemernú rýchlosť medzi dvoma systémami a nie o okamžitú rýchlosť vozidla v určitom bode. Vzdialenosť medzi systémami sa však môže zmeniť vplyvom vonkajších podmienok, napr. klimatických, alebo ich chybným nastavením pri údržbe.It is known that the driver has the technical means to control the speed of the vehicle. These are systems which are firmly installed on certain known sections along the railway lines. The vehicle is equipped with a receiving antenna, which detects its passage over the first system, and at the same time the Timer is switched on, which will expire when passing over the next system. Since the distance between the two systems and the Cas over which this vehicle has traveled is known, it is easy to calculate its speed. However, it should be noted that this is the average speed between the two systems and not the instantaneous speed of the vehicle at a certain point. However, the distance between the systems may change due to external conditions, e.g. climatic conditions, or their incorrect adjustment during maintenance.
Všeobecne sa dá považovať také meranie za menej presné.In general, such a measurement can be considered less accurate.
V dokumente DE-A-2630970 je opísaný spôsob zabezpečenia železničnej dopravy, podľa ktorého sa príkaz svetelnej signalizácie prenáša prenosovým zariadením do kontrolného zariadenia v prechádzajúcom vozidle.DE-A-2630970 discloses a method of providing rail transport according to which a light signal command is transmitted by a transmission device to a control device in a passing vehicle.
Na zaistenie vyššieho stupňa zabezpečenia sa v dokumente EP-A-0252199 navrhuje zariadenie na presný prenos údajov medzi okolím a prechádzajúcim vozidlom. Toto zariadenie je usporiadané jednak z pozemného prostriedku pevne zabudovaného na trati a jednak z palubného prostriedku umiesteného vo vozidle. Pozemný prostriedok je opatrený výsielačom, ktorý prenáša pomocou systému kódované návestné informácie. Palubný prostriedok je opatrený prijímačom spojeným s aspoň jednou anténou, ktorá je umiestená pod vozidlom tak, aby zachytila signál vysielacieho systému a počítačom na dekódovanie a spracovanie prijatých informácií. Současťou zariadenia je takisto prostriedok na kódovanie informácii signalizácie z trate, aktívny vysielač modulácie kmitočtu magnetického poľa, prostriedok porovnávania amplitúdy vyžarovaného magnetického poľa a prostriedok kontroly kmitočtu odosielaného z vysielacieho systému. V tomto prípade je prostriedok porovnávania amplitúdy vyžarovaného magnetického poľa a prostriedok kontroly kmitočtu pripojený na prostriedok na vydanie bezpečnostného signálu, ktorý v prípade poruchy zaistí v pozemnom prostriedku príslušnú bezpečnostnú akciu. Systém je v tomto prípade stále aktívny a správu vysiela nepretržite. Správa je zachytená anténou umiestenou vo vozidle a palubnými prostriedkami je analýzovaná.In order to ensure a higher degree of security, EP-A-0252199 proposes a device for accurately transmitting data between the environment and a passing vehicle. This device shall consist of both a ground vehicle fixed to the track and a vehicle located in the vehicle. The ground vehicle is equipped with a transmitter which transmits coded signaling information by means of a system. The on-board means is provided with a receiver connected to at least one antenna, which is placed under the vehicle so as to pick up the broadcast system signal and a computer for decoding and processing the received information. The apparatus also includes means for encoding track signaling information, an active magnetic field frequency modulation transmitter, means for comparing the amplitude of the radiated magnetic field, and means for controlling the frequency transmitted from the broadcasting system. In this case, the means of comparing the amplitude of the radiated magnetic field and the means of frequency control are connected to the means for issuing a safety signal which, in the event of a failure, provides the appropriate safety action in the ground means. In this case, the system is still active and sends the message continuously. The message is captured by the antenna located in the vehicle and is analyzed by the vehicle.
Zariadenie opísané v dokumente EP-A-0252199 je dosť zložité a drahé a samozrejme nie je nutné inštalovať také zariadenie v prípade, keď má byť vyslaný len príkaz na brzdenie a/alebo zastavenie vozidla na trati.The device described in EP-A-0252199 is rather complex and expensive, and of course there is no need to install such a device when only a command to brake and / or stop the vehicle on the track is to be sent.
V dokumente DE-A-2648383 je opísané zariadenie na meranie rýchlosti vozidla, napr. automobilu, zmeraním zmeny indukcie, ktorá nastane v zariadení v tvare indukčnej slučky umiestenej v zemi pri vjazdu vozidla do účinného poľa.DE-A-2648383 discloses a device for measuring vehicle speed, e.g. by measuring the change in induction that occurs in an induction loop shaped device located in the ground when the vehicle enters the effective field.
Podstata vynálezuSUMMARY OF THE INVENTION
Podstatou vynálezu je spôsob brzdenia a/alebo zastavenia vozidla železničného typu, pohybujúceho sa po koľaji. Vykonávanie tohto spôsobu nevyžaduje inštaláciu zložitého zariadenia a umožní presné meranie, ktoré nie je ovplyvniteľné vonkajšími podmienkami, napr. klimatickými, prípadne nepresným nastavením systémov pri ich údržbe.The subject of the invention is a method of braking and / or stopping a rail-type vehicle moving on a track. The implementation of this method does not require the installation of complex equipment and allows accurate measurements that are not influenced by external conditions, e.g. climatic or inaccurate setting of systems during their maintenance.
Podstatou vynálezu je takisto zariadenie na vykonávanie tohto spôsobu. Zariadenie obsahuje veľmi malý počet súčiastok a pri porovnateľnej spoľahlivosti s technikou opísanou v dokumente EP-A-0252199 je jeho cena nižšia.The invention also provides an apparatus for carrying out this method. The device contains a very small number of parts and, at a comparable reliability to the technique described in EP-A-0252199, its cost is lower.
Zariadenie podľa vynálezu je usporiadané známym spôsobom jednak z pozemného prostriedku zabudovaného na trati a opatreného aspoh jedným vysielacím systémom, ktorý vyžaruje magnetické pole, a jednak z palubného prostriedku opatreného aspoň jednou anténou, nej lepšie umiestenou pod vozom v smere vysielacieho systému.The device according to the invention is arranged in a known manner, on the one hand, from a ground-based means mounted on the track and provided with one transmission system which emits a magnetic field, and on the other hand from an on-board means equipped with at least one antenna better positioned underneath the car in the direction of the transmission system.
Spôsob podľa vynálezu spočíva v detekcii okamihu vstupu do magnetického poľa vyžarovaného systémom a okamihu výstupu z tohto poľa, pričom čas medzi týmito krajnými momentmi sa meria zodpovedajúcim prostriedkom, ktorý je umiestený v kabíne vozidla. Detekcia vstupu a výstupu z magnetického poľa sa robí pomocou antény umiestenej pod vozidlom.The method according to the invention consists in detecting the moment of entry into the magnetic field emitted by the system and the moment of exit from the field, the time between these extreme moments being measured by the corresponding means located in the vehicle cab. The detection of the input and output of the magnetic field is done using an antenna placed under the vehicle.
Vysielací systém výhodne vyžaruje kmitočtovo modulované magnetické pole prenášajúce údaje z kódovacieho zariadenia, ktoré je riadené napr. svetelnou signalizáciou.Preferably, the transmitting system emits a frequency modulated magnetic field transmitting data from a coding device that is controlled e.g. light signaling.
Dĺžka systému je kalibrovaná a informácia týkajúca sa jeho dĺžky môže byť prípadne prenesená v zakódovanej forme v správe, ktorá je anténou prenesená do palubného prostriedku.The length of the system is calibrated and information regarding its length may optionally be transmitted in coded form in a message that is transmitted to the vehicle by the antenna.
Keď je známy časový interval prechodu vozidla magnetickým poľom a dĺžka systému, je ľahké vypočítať rýchlosť vozidla.When the time interval of the vehicle passing through the magnetic field and the length of the system is known, it is easy to calculate the vehicle speed.
Keď bude rýchlosť vozidla vyššia napr. o 5 X než je nariadená rýchlosť, bude Ba aktivovať brzdový okruh.When the vehicle speed is higher, e.g. o 5 X than the commanded speed, Ba will activate the brake circuit.
Je výhodné, aby okamihy vstupu a výstupu z magnetického poľa neboli určené prekročením pevnej prahovej hodnoty tohto poľa, ale prekročením stanoveného percenta maximálneho magnetického poľa pri prechode nad príslušným systémom.It is preferred that the moments of entry and exit of the magnetic field are not determined by exceeding a fixed threshold value of that field, but by exceeding a specified percentage of the maximum magnetic field when passing over the respective system.
Podľa výhodného vyhotovenia vynálezu sa dá spoľahlivosť merania ešte zvýšiť. Meranie magnetického poľa sa urobí v dvoch krokoch, a to keď je magnetické pole maximálne a zodpovedá napr. logickému stavu 1, a keď je magnetické pole minimálne a zodpovedá napr. logickému stavu .According to a preferred embodiment of the invention, the measurement reliability can be further increased. The measurement of the magnetic field is made in two steps, when the magnetic field is maximum and corresponds e.g. 1, and when the magnetic field is minimal and corresponds e.g. logical state.
Podľa aplikácie sa teda dá kalkulovať buď s väčšou alebo so strednou hodnotou z oboch zistených rýchlostí.Thus, depending on the application, it is possible to calculate either a greater or a median of both detected speeds.
Vynález sa takisto týka zariadenia na vykonávanie spôsobu podľa vynálezu. Zariadenie je známym spôsobom usporiadané z pozemného prostriedku zabudovaného na trati a opatreného aspoň jedným systémom vyžarujúcim magnetické pole, pričom toto pole môže byť modulované, a z palubného prostriedku opatreného aspoň jednou anténou, ktorá je vhodne umiestená pod vozidlom tak, aby zachytila magnetické pole vyžarované systémom, ktorého dĺžka je kalibrovaná.The invention also relates to an apparatus for carrying out the method according to the invention. The device shall be arranged in a known manner from a ground-based ground vehicle equipped with at least one system emitting a magnetic field, which field may be modulated, and from a vehicle equipped with at least one antenna suitably positioned underneath the vehicle to detect the magnetic field emitted by the system. the length of which is calibrated.
Podľa výhodného vyhotovenia vysielací systém vyžaruje megnetické pole modulované údajmi z kódovacieho zariadenia, ktoré je pripojené na svetelnú signalizáciu.According to a preferred embodiment, the transmitting system emits a data-modulated megnetic field from a coding apparatus that is connected to the light signaling.
Systém je výhodne zabudovaný medzi obe koľajnice trate tak, že vzhľadom na os koľají je posunutý. Podľa výhodného .vyhotovenia tvorí systém jediný dostatočne pevný závit, ktorý pôsobí ako sekundárne vinutie transformátora megnetického okruhu v primárnom obvode, z ktorého vychádza frekvenčné modulovaný prúd.The system is preferably incorporated between the two rails of the track such that it is displaced relative to the track axis. According to a preferred embodiment, the system constitutes a single sufficiently strong thread which acts as the secondary winding of the megnetic circuit transformer in the primary circuit from which the frequency modulated current is output.
Primárne vinutie je výhodne uložené vnútri jediného závitu s osou kolmou na rovinu závitu, ktorý je v koľaji pripevnený pätkami v tvare S.Preferably, the primary winding is housed within a single thread with an axis perpendicular to the plane of the thread which is fixed in the track by S-shaped feet.
Prijímaciu anténu, ktorá je umiestená pod vozidlom, tvoria dve vinutia, z ktorých jedno je ľavotočivé a druhé • pravotočivé.The receiving antenna, which is located under the vehicle, consists of two windings, one of which is left-handed and the other • right-handed.

Príklady vyhotovenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Na obr. 1 a 2 sú dva príklady zariadenia podľa vynálezu. Zariadenie je usporiadané jednak z pozemného prostriedku X, ktorý je zabudovaný na trati a prípadne spojený so signalizačným alebo vysielacím zariadením 2, a jednak z palubného prostriedku 3, ktorý je umiestený vo vozidle a spojený s brzdovým okruhom.In FIG. 1 and 2 are two examples of a device according to the invention. The device consists of both ground-based X, which is installed on the track and possibly connected to a signaling or transmitting device 2, and, on the other hand, of vehicle-mounted means 3, which are located in the vehicle and connected to the brake circuit.
V prvom príklade na obr. 1 je zariadenie opatrené jediným systémom B· Funkciou zariadenia je v tomto prípade iba vydať príkaz na brzdenie, alebo pripadne na zastavenie vozidla, keď systém vysiela správu na zastavenie.In the first example of FIG. 1, the device is provided with a single system B · The function of the device in this case is only to issue a braking command, or eventually to stop the vehicle when the system sends a stop message.
Na obr. 2 je znázornený druhý príklad, v ktorom iný systém £ (v anglickej terminológii speed trap) má lunkciu riadenia rýchlosti. V tomto prípade zariadenie umožni po prechode vozidla cez prvý systém £ určit jeho rýchlosť a pripadne aktivovať brzdový okruh vozidla, keď rýchlosť prekročí napr. 5 * nariadenej rýchlosti.In FIG. 2 shows a second example in which another system 6 (in English speed trap terminology) has a speed control function. In this case, the device makes it possible, after passing the vehicle through the first system 6, to determine its speed and optionally to activate the vehicle brake circuit when the speed exceeds e.g. 5 * cruising speed.
Je treba poznamenať, že každý systém (tedy i systém &) umožní urobiť kontrolu rýchlosti vozidla.It should be noted that each system (including the & system) will allow the vehicle speed to be checked.
Na presné zmeranie rýchlosti pri prechode vozidla nad jedným systémom je nutné poznať jeho presnú dĺžku a okamihy vstupu a výstupu z magnetického poľa, ktoré vyžaruje. Informácia o dĺžke systému môže byť napr. zakódovaná a oznámená v správe vysielanej týmto systémom.To accurately measure the speed of a vehicle passing over one system, it is necessary to know its exact length and the moments of entry and exit of the magnetic field it emits. The system length information may be e.g. encoded and reported in a message transmitted by this system.
Stanovenie okamihu vstupu a výstupu z magnetického poľa je trocha zložitejšie, pretože nominálna amplitúda v strede systému zachytená anténou sa podstatne mení vplyvom rôznych okolnosti, napr. vplyvom napájacieho napätia zosilňovača pozemného prostriedku, vzdialenosti, ktorá ho oddeľuje od systému, výSky vzduchovej medzery medzi systémom a anténou prijímača, ktorá sa takisto mení v závislosti na opotrebení kolies a koľajníc a vplyvom prípadného bočného posuvu antény proti systémom v zákrutách ap.Determining the moment of input and output from the magnetic field is somewhat more difficult because the nominal amplitude at the center of the system captured by the antenna varies considerably due to various circumstances, e.g. due to the supply voltage of the ground amplifier, the distance that separates it from the system, the air gap height between the system and the receiver antenna, which also varies depending on the wear of the wheels and rails and the lateral displacement of the antenna.
Použitie jedinej pevnej prahovej úrovne prijatej palubným prostriedkom by viedlo k nadsadeniu dĺžky systému z ktorého vychádza silný signál a teda k podceneniu rýchlosti, pri ktorej je systém prekročený.The use of a single fixed threshold level received by the vehicle would lead to an overestimation of the length of the system from which the strong signal emits and thus to an underestimation of the speed at which the system is exceeded.
Je najmä výhodné, aby sa okamihy vstupu a výstupu z magnetického poľa neurčovali prekročením hodnoty pevného prahu poľa, ale prekročením stanoveného percenta maximálneho magnetického poľa zisteného nad systémom v priebehu skúšky.It is particularly preferred that the moments of entry and exit of the magnetic field are not determined by exceeding a fixed field threshold value, but by exceeding a specified percentage of the maximum magnetic field detected above the system during the test.
Iná dôležitá príčina nepresnosti v určení okamihu vstupu a výstupu z magnetického poľa je ekutečnosť, že magnetické pole zachytené anténou je podľa výhodného vyhotovenia vynálezu modulované správou vysllanou systémom: takisto v prípade prenosu kmitočtovou moduláciou spôsobí obmedzenie priepustného pásma vyžadovaného normami vysielania moduláciu amplitúdy, ktorá sa prejaví tým, že amplitúda prijatého signálu v jednom bode pozdĺž systému závisí nielen na úsečke tohto bodu vzhľadom k stredu systému, ale aj na skutočnosti, že bit prijatej správy v tomto okamihu je na stave 1 alebo 0. To vedie k odchýlke úsečky bodu vstupu a výstupu z magnetického poľa v závislosti na momentálnom tvarovánl predávanej správy.Another important cause of inaccuracy in determining the moment of input and output of the magnetic field is the fact that the magnetic field captured by the antenna is modulated by the system message in a preferred embodiment of the invention: also in the case of frequency modulation transmission in that the amplitude of the received signal at one point along the system depends not only on the line segment of that point relative to the center of the system, but also on the fact that the received message bit at this point is at 1 or 0. This leads to from the magnetic field depending on the current shape of the sold message.
Je výhodné, aby celé spracovanie týkajúce sa stanovenie rýchlosti bolo urobené dvakrát: nejprv sa zisti maximálne magnetické pole a okamihy vstupu a výstupu napr. pri logickom stave 1 a z toho sa vypočíta prvá rýchlosť, potom sa zisti magnetické pole a okamihy vstupu a výstupu pri logickom stave 0 a z toho sa stanov! druhá rýchlosť.It is preferred that the entire speed determination process be performed twice: first, the maximum magnetic field and the moments of entry and exit, e.g. in logic state 1 and the first velocity is calculated, then the magnetic field and the moments of input and output in logic state 0 are determined and from this determined! second speed.
Na obr. 3 je znázornený systém pozemného prostriedku. Systém, ktorý vyžaruje kalibrované magnetické pole, tvorí jediný závit z nehrdzavejúcej ocele, ktorého dĺžka je 150 cm a šírka 30 cm. Závit je vlastne sekundárny obvodo transformátora magnetického okruhu v primárnom obvode, z ktorého kontinuálne vychádza modulovaný prúd. Je treba poznamenať, že dĺžka závitu je prispôsobená dĺžke správy prenášanej z trate do vlaku a takisto maximálnej rýchlosti vlaku.In FIG. 3 shows a ground vehicle system. The system emitting a calibrated magnetic field consists of a single stainless steel thread, 150 cm long and 30 cm wide. The thread is actually the secondary circuit of the magnetic circuit transformer in the primary circuit from which the modulated current is continuously output. It should be noted that the length of the thread is adapted to the length of the message transmitted from the line to the train as well as the maximum train speed.
Primárne vinutie je výhodne uložené v osi vnútri jediného závitu a kolmo na jeho rovinu. Dostatočne pevný jediný závit je vložený medzi obe koľajnice a z oboch strán prichytený pätkami v tvare S. Primárne vedenie je výhodne zaliate do puzdra pripevneného pod pripevfíovaclmi pätkami.The primary winding is preferably mounted in an axis within a single thread and perpendicular to its plane. A sufficiently rigid single thread is inserted between the two rails and attached on both sides by S-shaped feet. The primary guide is preferably cast into a housing attached below the fixing feet.
Systém je umiestený pozdĺžne medzi obe koľajnice v smere pohybu vlaku a vzhľadom na os koľaje je posunutý.The system is located longitudinally between the two rails in the direction of train movement and is displaced relative to the rail axis.
Riadiaci obvod zaisťuje prísun takého napätia, ktoré umožni riadiť relé KTBL s logickým výstupom typu porucha/bezpečie, keď je závitom generované magnetické pole dostačujúce a so správnym kmitočtom.The control circuit provides a voltage supply that allows to control the KTBL relay with a fault / safety logic output when the threaded magnetic field is sufficient and at the correct frequency.
Relé KTBL môže byť takisto použité na okamžitú detekciu prípadnej poruchy systému alebo kódovacieho zariadenia.The KTBL relay can also be used to immediately detect a possible system or encoder failure.
Informácia prenášaná do vozidla vysielacím systémom je generovaná kódovacím zariadením umiesteným v blízkosti majáka. Kódovacie zariadenie je spojené cez prúdový transformátor so svetelnou signalizáciou a poskytuje tak návestnú informáciu. Rozhranie so systémom signalizácie môže byť urobené použitím spojenia kódovacieho zariadenia buď s logickým obvodom signalizácie typu relé prucha/bezpeCie alebo b modulom Trackside Functional Module (TFM) typu Solid State Interlocking (SSI).The information transmitted to the vehicle by the broadcasting system is generated by an encoder located near the beacon. The coding apparatus is coupled to the light signaling via a current transformer and provides signaling information. Interfaces with the signaling system can be made using a connection of the encoder either to a logic alarm / safety relay logic circuit or b to a Solid State Interlocking (SSI) Trackside Functional Module (TFM).
Na obr. 4 je znázornený palubný prostriedok, ktorý je opatrený aspott jednou vonkajšou prijímacou anténou £. Anténa je umiestená pod vozidlom 3. a vzhľadom na os koľaje v smere cesty vozidla je posunutá. Prijímacia anténa je výhodne urobená z pravotočivého a ľavotočivého vinutia na tej istej osi. Také usporiadanie umožní, aby anténa nereagovala na vysielacie systémy aktívne v opačnom smere cesty, alebo na súbežných koľajoch. Toto vyhotovenie umožní teda bezpeCný kontakt s príslušným vysielacím systémom. Magnetické toky prijímané pravotočivým a ľavotočivým vinutím antény sú sfázované hneď ako pod anténou prechádza príslušný systém. Naopak, keď uvedená anténa zachytí systém na súbežnej koľaji alebo v opačnom smere cesty vozidla, jej obe vinutia zachytia magnetické toky toho istého smeru a v dôsledku toho sú signály prijaté týmito protismernými vinutiami v protifáze. To umožní palubnému prostriedku bezpečne rozlíšiť príslušné vysielacie systémy.In FIG. 4 shows an on-board means which is provided with at least one external receiving antenna 6. The antenna is located below the vehicle 3 and is displaced relative to the track axis in the direction of travel of the vehicle. The receiving antenna is preferably made of a right-handed and a left-handed winding on the same axis. Such an arrangement will allow the antenna not to respond to broadcast systems active in the opposite direction of travel or to parallel tracks. This embodiment thus enables safe contact with the respective broadcasting system. The magnetic fluxes received by the clockwise and counterclockwise windings of the antenna are phased as soon as the respective system passes under the antenna. Conversely, when said antenna intercepts the system on a parallel track or in the opposite direction of the vehicle's travel, its two windings pick up magnetic fluxes in the same direction and, as a result, the signals received by these upstream windings are in phase. This will allow the vehicle to safely distinguish the respective broadcast systems.
Je dostatoCné, aby hnacie vozidlo súpravy bolo opatrené jedinou anténou umiestenou pod jeho kabínou. V obojsmerných súpravách je anténa inštalovaná na prednej a zadnej časti súpravy. Každá anténa je teda určená danému smeru cesty.It is sufficient that the traction unit of the kit is provided with a single antenna located below its cab. In bidirectional sets, the antenna is installed on the front and rear of the set. Thus, each antenna is intended for a given direction of travel.
Hneď ako vozidlo prechádza nad systémom, je prenos urobený moduláciou kmitočtu magnetického poľa vyžarovaného systémom vyladeným na 100 KHz.As soon as the vehicle passes over the system, the transmission is made by modulating the frequency of the magnetic field emitted by the system tuned to 100 KHz.
