Description

PRECINTO ELECTRÓNICO. OBJETO DE LA INVENCIÓN. La invención que nos ocupa, se refiere a un precinto electrónico que tiene por objeto generar un aviso cuando se produce una manipulación del precinto. ELECTRONIC SEAL.

The invention is applicable to any device that is desired to seal such as counters of any type, safety devices, etc.
Una particular aplicación del precinto electrónico, se refiere a su uso como detector de manipulación en surtidores de carburantes, teniendo por objeto generar un aviso cuando se produce una manipulación del surtidor, de modo que el usuario pueda detectar la posible manipulación fraudulenta del surtidor, al conocer la circunstancia de que la cantidad de combustible suministrado no corresponde con la cantidad de combustible señalado en el visualizador previsto en el surtidor.A particular application of the electronic seal refers to its use as a tamper detector in fuel dispensers, with the purpose of generating a warning when a manipulation of the dispenser occurs, so that the user can detect the possible fraudulent manipulation of the dispenser, when Know the circumstance that the quantity of fuel supplied does not correspond to the quantity of fuel indicated on the display provided in the dispenser.
Además, en este caso, la invención tiene por objeto propor- cionar un segundo visualizador en el que se muestra la cantidad real de combustible suministrado.Furthermore, in this case, the object of the invention is to provide a second display in which the actual amount of fuel supplied is shown.
Otro objeto de la invención consiste en bloquear el funcionamiento del surtidor al detectar una manipulación.Another object of the invention is to block the operation of the dispenser by detecting a manipulation.
La invención especialmente concebida para su aplicación en surtidores de gasolina, gasóleo, etc., evidentemente puede ser aplicable a cualquier tipo de surtidor.The invention especially designed for application in fuel pumps, diesel, etc., can obviously be applicable to any type of dispenser.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Convencionalmente es conocido el uso de precintos para contadores y dispositivos similares, los cuales están constituidos por un elemento de cierre, como puede ser un alambre, que cierra el acceso a la caja o contenedor del contador, de modo que el precinto se remata mediante una pieza de plomo por la que se introducen los extremos del alambre, materializándose el precinto al presionar mediante una máquina el plomo, presionando los alambres para immoviiizarios impidiendo el acceso al contenedor. A pesar de ello, una forma de manipulación del precinto puede llevarse a cabo por el corte del alambre, circunstancia que representa la notoria manipulación del dispositivo precintado.Conventionally the use of seals for meters and similar devices is known, which are constituted by a closing element, such as a wire, which closes the access to the meter box or container, so that the seal is terminated by means of a piece of lead through which the ends of the wire are introduced, the seal materializing by pressing the lead through a machine, pressing the wires to immobilize preventing access to the container. Despite this, a way of Sealing of the seal can be carried out by cutting the wire, a circumstance that represents the notorious manipulation of the sealed device.
Aún más, este precinto presenta el inconveniente añadido de que es fácilmente manipulable sin necesidad de cortar el alambre, de modo que se permite falsear la cuenta de los contadores sin que ello sea detectado.Moreover, this seal has the added drawback that it is easily manipulated without the need to cut the wire, so that it is possible to falsify the counting account without it being detected.
Por otra parte, en el estado de la técnica es sobradamente conocido el uso de surtidores de carburantes, los cuales están constituidos por una bomba de absorción del combustible almacenado en un depósito, estando dicha bomba relacionada con un medidor volumétrico que a su vez está conectado a un codificador, de forma que éste proporciona una señal proporcional a la cantidad de combustible suministrado. Además, el codificador está conectado a medios electrónicos de cálculo y presentación visual del combustible suministrado, de forma que el usuario conoce la cantidad de combustible adquirido.On the other hand, in the state of the art the use of fuel pumps is well known, which are constituted by a fuel absorption pump stored in a tank, said pump being related to a volumetric meter which in turn is connected to an encoder, so that it provides a signal proportional to the amount of fuel supplied. In addition, the encoder is connected to electronic means of calculation and visual presentation of the fuel supplied, so that the user knows the amount of fuel purchased.
Al ponerse el surtidor en servicio por primera vez, el Ministerio de Industria ajusta el medidor volumétrico al valor real de suministro, para lo que se realiza una calibración mediante la medida con probetas especiales. Una vez realizada esta operación se precintan estos elementos para lo que quedan alojados en un contenedor cuya puerta o tapa de acceso constituye el medio de precintado.When the supplier is put into service for the first time, the Ministry of Industry adjusts the volumetric meter to the actual supply value, for which a calibration is performed by measuring with special specimens. Once this operation has been carried out, these elements are sealed so that they are housed in a container whose door or access cover constitutes the sealing means.
El precintado se efectúa mediante un elemento de precinto, como puede ser un alambre o similar, el cual se remata mediante una pieza de plomo por la que se introducen los extremos del alambre, de modo que mediante una máquina se presiona sobre el plomo impidiéndose el acceso al contenedor.The sealing is carried out by means of a sealing element, such as a wire or the like, which is finished off by a piece of lead through which the ends of the wire are introduced, so that by means of a machine it is pressed on the lead preventing the container access
Este tipo de precintos, tal como se ha indicado anteirormente, presentan el inconveniente de que son fácilmente manipuiables, de forma que se puede variar el calibrado del medidor volumétrico con lo que la cantidad de combustible suministrado es menor que la cantidad de combustible mostrada en los medios de visualización, lo que representa un fraude. También existe la posibilidad de realizar operaciones fraudulentas sobre los medios electrónicos de cálculo de la cantidad de combustible aspirado con la bomba, para lo que se modifica la memoria del microprocesador de los medios electrónicos, de forma que al recibir los impulsos del codificador se resta un tanto por ciento menos de estos impulsos, de manera que la lectura mostrada en los medios de visualización no corresponde con el combustible suministrado. Esta manipulación del cambio de memoria puede efectuarse mediante la introducción de claves desde el exterior, las cuales pueden ser enviadas de distintas formas, como puede ser mediante una línea eléctrica, mediante señales infrarrojas, vía radio, etc.These types of seals, as indicated above, have the disadvantage that they are easily manipulated, so that the calibration of the volumetric meter can be varied so that the amount of fuel supplied is less than the amount of fuel shown in the display media, which represents a fraud. There is also the possibility of performing operations fraudulent on the electronic means for calculating the amount of fuel aspirated with the pump, for which the microprocessor memory of the electronic means is modified, so that when receiving the encoder pulses, one percent less of these impulses is subtracted , so that the reading shown on the display means does not correspond to the fuel supplied. This manipulation of the memory change can be done by entering keys from the outside, which can be sent in different ways, such as through an electric line, using infrared signals, via radio, etc.
Para ello, en el surtidor se deben incorporar los correspondientes receptores que hagan posible la llegada de dichas claves, como pueden ser receptores de infrarrojos, de radio, etc. Estos receptores envían una señal al microprocesador del equipo electrónico de forma que reste el tanto por ciento indicado del carburante.For this, the corresponding receivers that make possible the arrival of said keys, such as infrared, radio receivers, etc., must be incorporated into the dispenser. These receivers send a signal to the microprocessor of the electronic equipment so that it subtracts the indicated percentage of the fuel.

DESCRIPTION OF AN EXAMPLE OF EMBODIMENT OF THE INVENTION
A continuación se realiza una descripción de la invención basada en las figuras anteriormente comentadas.Below is a description of the invention based on the figures mentioned above.
En primer lugar se describe la realización básica de la invención para precintar un dispositivo, para lo que se dispone una caja 1 independiente que en su interior incluye un emisor óptico 2, como puede ser un emisor de luz, y un receptor óptico 3, uniéndose ambos mediante un conductor de luz, como puede ser una fibra óptica 4, la cual constituye el elemento de cierre del contenedor del dispositivo a precintar, para lo que dicho elemento de cierre sale a través de la caja y pasa por los correspondientes orificios previstos en la puerta o tapa de acceso al contenedor tal y como se efectúa convencionalmente.First, the basic embodiment of the invention for sealing a device is described, for which an independent box 1 is provided which inside includes an optical emitter 2, such as a light emitter, and an optical receiver 3, joining both by means of a light conductor, such as an optical fiber 4, which constitutes the closing element of the container of the device to be sealed, for which said closing element exits through the box and passes through the corresponding holes provided in the door or lid for access to the container as it is done conventionally.
El receptor 3 está conectado a un circuito detector de falta de recepción 5 y éste a un indicador acústico y/u óptico 6.The receiver 3 is connected to a non-reception detector circuit 5 and this to an acoustic and / or optical indicator 6.
Basándose en la descripción realizada se comprende fácilmente que para acceder al interior del contenedor 1 es preciso realizar el corte de la fibra óptica 4, de modo que se interrumpe el camino de conducción de las señales ópticas generadas en el emisor, con lo que no llegan al receptor, circunstancia que es detectada por el circuito 5 el cual activa el indicador acústico y/u óptico 6 señalizando que el precinto ha sido cortado.Based on the description made, it is easily understood that to access the interior of the container 1 it is necessary to cut the optical fiber 4, so that the conduction path of the optical signals generated in the transmitter is interrupted, so that they do not arrive to the receiver, circumstance that is detected by circuit 5 which activates the acoustic and / or optical indicator 6 indicating that the seal has been cut.
El indicador acústico y/u óptico puede encontrarse situado en un lugar remoto, de modo que esta circunstancia pueda ser conocida en un centro de control.The acoustic and / or optical indicator can be located in a remote place, so that this circumstance can be known in a control center.
En la figura 2 se muestra otro ejemplo de realización de la invención, en el que el emisor 2 es un emisor de impulsos cuyo tren puede ser variado tanto en número como en tiempo, para lo que se ha previsto una memoria 8 que está conectada a un codificador 7 y éste al emisor 2 y a un oscilador 9, de forma que el código almacenado en la memoria 8 es codificado según los impulsos producidos por el oscilador 9, emitiéndose mediante el emisor 2 el código almacenado en la memoria 8. Dicho código puede ser variado mediante un teclado o micro rruptores 10.Another example of embodiment of the invention is shown in Figure 2, in which the transmitter 2 is a pulse transmitter whose train it can be varied both in number and in time, for which a memory 8 is provided that is connected to an encoder 7 and this to the transmitter 2 and an oscillator 9, so that the code stored in the memory 8 is encoded according to the impulses produced by the oscillator 9, the code stored in the memory being emitted by the transmitter 2. This code can be varied by means of a keyboard or microswitches 10.
Estas características permiten personalizar cada precinto según las necesidades del usuario. Para mantener el estado de la memoria invariable, ésta está conectada a una batería 11 de modo que aunque se produzca un corte del suministro eléctrico se mantiene el código almacenado.These features allow you to customize each seal according to the user's needs. To maintain the state of the invariable memory, it is connected to a battery 11 so that even if there is a power outage, the stored code is maintained.
El receptor 3 está conectado a un decodificador 12 y éste a un comparador 13, el cual recibe en su otra entrada la salida del codificador 7, de modo que compara el código emitido y recibido, y en caso de no ser idénticos genera una señal de activación de un circuito detector de manipulación 14.The receiver 3 is connected to a decoder 12 and this to a comparator 13, which receives in its other input the output of the encoder 7, so that it compares the code emitted and received, and in case of not being identical it generates a signal of activation of a tamper detector circuit 14.
Evidentemente, el código emitido no va a coincidir con el código recibido, siempre y cuando se efectúe una manipulación sobre la fibra óptica 4, como puede ser realizar el corte de la misma.Obviously, the code issued will not match the code received, as long as a manipulation is made on the optical fiber 4, such as cutting it.
El detector de manipulación 14 genera una señal para enviar a un indicador 6 óptico y/o acústico, señalizando la manipulación.The manipulation detector 14 generates a signal to send to an optical and / or acoustic indicator 6, signaling the manipulation.
Además el detector de manipulación 14 puede estar conectado a un sintetizador de voz 15 mediante el cual se emite un mensaje hablado, previamente grabado en dicho sintetizador.In addition, the manipulation detector 14 can be connected to a speech synthesizer 15 by means of which a spoken message is emitted, previously recorded in said synthesizer.
También cabe la posibilidad de que el detector de manipulación 14 esté conectado a un emisor de radio 16 o a un módemIt is also possible that the tamper detector 14 is connected to a radio transmitter 16 or a modem
17, de manera que cuando se detecte una manipulación de la fibra óptica 4, esta circunstancia se señaliza hacia un lugar remoto, como puede ser un centro de control.17, so that when a manipulation of the optical fiber 4 is detected, this circumstance is signaled towards a remote place, such as a control center.
Según otra realización de la invención, el precinto, además, cuenta con un detector 18 de apertura/cierre de la tapa o puerta de acceso a la caja 1 , que está conectado a un temporizador 19, que a su vez está conectado al detector de manipulación 14 y a la memoria 8, quedando estos dos últimos unidos entre sí. Además, el detector de manipulación 14 está conectado a un circuito 20 de corte de la alimentación del dispositivo precintado, para lo que la alimentación del dispositivo precintado pasa a través del circuito 20.According to another embodiment of the invention, the seal also has a detector 18 for opening / closing the lid or access door to the box 1, which is connected to a timer 19, which in turn is connected to the detector manipulation 14 and memory 8, these last two being joined together. In addition, the detector Handling 14 is connected to a circuit 20 for cutting the feed of the sealed device, for which the feeding of the sealed device passes through the circuit 20.
Esta disposición permite que una vez que es detectada la apertura de la tapa o puerta de la caja 1, el circuito detector de manipulación 14 no tiene en cuenta las señales del comparador 13 hasta que no ha transcurrido el tiempo de temporización, de manera que una vez transcurrido dicho tiempo verifica las señales del comparador, de modo que si la señal emitida y recibida no coinciden actúa sobre el circuito de corte 20 de la alimentación del dispositivo precintado, bloqueando su funcionamiento.This arrangement allows that once the opening of the lid or door of the box 1 is detected, the manipulation detector circuit 14 does not take into account the signals of the comparator 13 until the timing time has elapsed, so that a After this time has elapsed, check the comparator signals, so that if the emitted and received signal does not match, it acts on the cutting circuit 20 of the supply of the sealed device, blocking its operation.
Además, si durante el tiempo de temporización se introduce el código de seguridad, a través del teclado 10, la memoria 8 genera una señal para el detector de manipulación 14 el cual actúa sobre el circuito de corte de la siguiente forma: a) si el circuito de corte 20 mantiene bloqueada la alimentación del dispositivo precintado, efectúa el desbloqueo del mismo. b) si el circuito de corte 20 mantenía en funcionamiento al dispositivo precintado, y se introduce el código de seguridad durante el tiempo de temporización, se impide el bloqueo del dispositivo precintado.In addition, if the security code is entered during the timing, through the keypad 10, the memory 8 generates a signal for the manipulation detector 14 which acts on the cutting circuit as follows: a) if the cutting circuit 20 keeps the power supply of the sealed device blocked, it unlocks it. b) if the cutting circuit 20 kept the sealed device in operation, and the security code is entered during the timing time, blocking of the sealed device is prevented.
Además, cuando se efectúa el cierre de la tapa no se pone el precinto en funcionamiento hasta que no transcurre el tiempo temporizado.In addition, when the lid is closed, the seal is not put into operation until the timed time elapses.
Igualmente, si se abre y cierra la tapa sin que se introduzca el código de seguridad, se produce el bloqueo del dispositivo precintado.Likewise, if the lid is opened and closed without entering the security code, the sealing of the sealed device occurs.
El circuito de corte 20 puede estar determinado por un relé biestable gobernado por el detector de manipulación 14. Existe además un indicador, como puede ser un diodo led que señaliza, una vez cerrada la tapa, o puerta, cuando ha transcurrido el tiempo de temporización quedando el circuito en funcionamiento.The cutting circuit 20 can be determined by a flip-flop relay governed by the manipulation detector 14. There is also an indicator, such as a LED that signals, once the cover is closed, or door, when the timing time has elapsed. leaving the circuit in operation.
Cuando el precinto electrónico es aplicable para la detección de posibles manipulaciones en surtidores de carburantes, el surtidor de combustible 21 cuenta con una bomba 22 que está relacionada con un medidor volumétrico 23, que a su vez, está conectado a un generador de impulsos (encoder) 24, de modo que el generador de impulsos (encoder) 24 proporciona una señal proporcional al combustible aspirado por la bomba 22. Además, el surtidor 21 cuenta con un circuito electrónico 25 de cálculo y presentación visual del combustible suministrado.When the electronic seal is applicable for the detection of possible manipulations in fuel pumps, the fuel pump 21 has a pump 22 which is related to a volumetric meter 23, which in turn is connected to a pulse generator (encoder) 24, so that the pulse generator (encoder) 24 provides a signal proportional to the fuel sucked by the pump 22. In addition, the dispenser 21 has an electronic circuit 25 for calculation and visual presentation of the fuel supplied.
Tanto la bomba 22 como el medidor volumétrico 23 y el generador de impulsos (encoder) 24 se encuentran alojados en un contenedor 26, cuya tapa o puerta de acceso está precintada mediante una fibra óptica 4 la cual está conectada a un emisor de luz 2 y a un receptor de luz 3 que se encuentran incluidos en una caja 27 independiente.Both the pump 22 and the volumetric meter 23 and the pulse generator (encoder) 24 are housed in a container 26, whose lid or access door is sealed by an optical fiber 4 which is connected to a light emitter 2 and a light receiver 3 which are included in a separate box 27.
La caja 27, igualmente, se encuentra precintada mediante la fibra óptica 4 que constituye un elemento de cierre. Tal como se ha indicado, el emisor 2 está conectado a un codificador 7 que a su vez está unido a una memoria 8 y a un oscilador 9.The box 27, likewise, is sealed by the optical fiber 4 which constitutes a closing element. As indicated, the transmitter 2 is connected to an encoder 7 which in turn is connected to a memory 8 and an oscillator 9.
Igualmente, la memoria 8 está conectada a microrruptores o un teclado 10 y a una batería 11. Haciendo referencia a lo anteriormente explicado, esta estructura permite introducir un código a través del teclado 10 que es almacenado en la memoria 8 y mediante el codificador 7, gobernado por el oscilador 9, se produce un tren de pulsos que son emitidos por el emisor 2. Por tanto el tren de pulsos es programable. El código emitido por el emisor 2 es recepcionado en el receptor 3 que tras su decodificación en el decodificador 12 se envía al comparador 13, de modo que compara el código emitido con el recibido, teniendo que ser ambos iguales, salvo en el caso de que la fibra óptica haya sido manipulada o cortada, en cuyo caso dichos códigos no coinciden generando el comparador 13 una señal que es enviada a un circuito de detección de manipulación 14 que genera una señal indicativa de que la fibra óptica 4 ha sido manipulada, activando un indicador 6 acústico y/u óptico, y mostrando esta incidencia en una pantalla 28. Igualmente, esta señal procedente del circuito de detección de manipulación 14 puede ser enviada a un centro de control remoto mediante un módem 17 o un transmisor de radio 16.Likewise, the memory 8 is connected to microswitches or a keyboard 10 and a battery 11. Referring to the above, this structure allows entering a code through the keyboard 10 that is stored in the memory 8 and via the encoder 7, governed by the oscillator 9, a train of pulses is produced that are emitted by the emitter 2. Therefore the pulse train is programmable. The code issued by the sender 2 is received in the receiver 3 which after decoding in the decoder 12 is sent to the comparator 13, so that it compares the code issued with the received one, having to be both the same, except in the case that the optical fiber has been manipulated or cut, in which case said codes do not coincide generating the comparator 13 a signal that is sent to a manipulation detection circuit 14 that generates a signal indicating that the optical fiber 4 has been manipulated, activating a acoustic and / or optical indicator 6, and showing this incidence on a screen 28. Likewise, this signal from the detection circuit Handling 14 can be sent to a remote control center via a modem 17 or a radio transmitter 16.
Por tanto, siempre que la fibra óptica 4 sea manipulada para tratar de acceder al interior del contenedor 26 o de la caja 27, esto es detectado y señalizado debidamente de la forma descrita con anterioridad.Therefore, as long as the optical fiber 4 is manipulated to try to access the interior of the container 26 or the box 27, this is properly detected and signaled in the manner described above.
Además, la alimentación de la bomba 22 se efectúa a través de la caja 27, para lo que la tensión de alimentación 29 entra a la caja 21 , y a través de unos relés biestables 30 se conecta a la bomba 22. De esta forma, cuando el detector de manipulación 14 ha detectado una manipulación en la fibra óptica 4, produce el corte de la alimentación de la bomba 22 mediante la activación de los relés biestables 30.In addition, the supply of the pump 22 is carried out through the box 27, for which the supply voltage 29 enters the box 21, and through bistable relays 30 is connected to the pump 22. Thus, when the manipulation detector 14 has detected a manipulation in the optical fiber 4, causes the power supply of the pump 22 to be cut by activating the bistable relays 30.
Por tanto, los relés biestables 30 determinan un medio de corte/conexión de la alimentación de la bomba 22.Therefore, the bistable relays 30 determine a means of cutting / connecting the supply of the pump 22.
En una realización preferida, la señal procedente del generador de impulsos (encoder) 24 se entrega al circuito electrónico de cálculo y presentación visual 25 a través de un relé biestable 31 ubicado en el interior de la caja 27, de modo que igualmente este relé puede ser gobernado por el circuito de detección de manipulación.In a preferred embodiment, the signal from the pulse generator (encoder) 24 is delivered to the electronic calculation and visual presentation circuit 25 through a bistable relay 31 located inside the box 27, so that this relay can also be governed by the tamper detection circuit.
Esta estructura permite incluir en la caja 27 un circuito de cálculo 32 del combustible suministrado y de presentación 33 de dicho combustible suministrado por la bomba 22.This structure allows a calculation circuit 32 of the fuel supplied and display 33 of said fuel supplied by the pump 22 to be included in the box 27.
Además, en la caja 21 se ha previsto un circuito de control de entradas digitales y analógicas 34 que recibe las señales procedentes del circuito de cálculo y presentación visual 25 incluido en el surtidor 21.In addition, a digital and analog input control circuit 34 is provided in the box 21 that receives the signals from the calculation and visual presentation circuit 25 included in the dispenser 21.
Tanto el circuito 32 como el 34 se encuentran conectados a un comparador 35, que compara el valor de combustible suministrado proporcionado por el propio equipo del surtidor 21 y el calculado por el circuito adicional 32 y 33 de cálculo y representación visual del suministro del combustible, de modo que si el circuito electrónico de cálculo y presentación visual 25 del surtidor 21 ha sido manipulado, la señal proporcionada por el circuito 34 no coincide con la proporcionada por el circuito 32, lo cual es detectado por el comparador 35 que genera una señal para un circuito detector de manipulación 36, el cual activa cualquiera de los medios 6, 16, 17 o 28, tal y como fue comentado anteriormente para el caso del circuito de detección de manipulación 14. Igualmente, el circuito detector de manipulación 36 se encuentra conectado a los relés 30 y 31 para realizar el corte de la alimentación de la bomba 22 en caso de que el carburante suministrado no coincida con el carburante mostrado en el surtidor 21.Both circuit 32 and 34 are connected to a comparator 35, which compares the value of fuel supplied by the dispenser equipment 21 itself and that calculated by the additional circuit 32 and 33 for calculation and visual representation of the fuel supply, so that if the electronic calculation and visual presentation circuit 25 of the dispenser 21 has been manipulated, the signal provided by circuit 34 does not match that provided by circuit 32, which is detected by comparator 35 that generates a signal for a tamper detector circuit 36, which activates any of the means 6, 16, 17 or 28, as previously mentioned in the case of the tamper detection circuit 14. Similarly, the tamper detector circuit 36 is connected to the relays 30 and 31 to make the cut of the supply of the pump 22 in case the supplied fuel does not match the fuel shown in the dispenser 21.
Una forma de manipulación podría consistir en cortar la alimentación de los circuitos contenidos en la caja 27, para lo que en la misma se incluye un circuito de detección de tensión de alimentación para la bomba 22, de modo que si se ha cortado la alimentación de los circuitos incluidos en la caja 27, dicho detector 37 activa los relés biestables 30 y 31 quedando el surtidor 21 bloqueado.One form of manipulation could be to cut the power supply of the circuits contained in the box 27, for which a power supply voltage detection circuit for the pump 22 is included, so that if the power supply has been cut off the circuits included in the box 27, said detector 37 activates the bistable relays 30 and 31 with the dispenser 21 blocked.
Además, la invención puede incluir ventajosamente un detector 38 de apertura/cierre de la tapa o puerta de acceso a la caja 21 que está conectado a un temporizador 39, que a su vez está conectado al detector de manipulación 14 y a la memoria 8, quedando estos dos últimos unidos entre sí. Además, el detector de manipulación 14 está conectado a los relés 30 y 31, de modo que esta disposición permite que una vez que es detectada la apertura de la tapa o puerta de la caja 21 el circuito detector de manipulación 14 no tiene en cuenta las señales del comparador 9 hasta que no ha transcurrido el tiempo de temporización, de manera que una vez transcurrido dicho tiempo verifica las señales del comparador, de modo que si la señal emitida y recibida no coinciden actúa sobre los relés 30 y 31 bloqueando el funcionamiento del surtidor 21.In addition, the invention can advantageously include a detector 38 for opening / closing the lid or access door to the box 21 which is connected to a timer 39, which in turn is connected to the manipulation detector 14 and the memory 8, remaining These last two joined together. In addition, the tamper detector 14 is connected to relays 30 and 31, so that this arrangement allows that once the opening of the lid or door of the box 21 is detected, the tamper detector circuit 14 does not take into account the comparator signals 9 until the timing time has elapsed, so that after said time it verifies the comparator signals, so that if the emitted and received signal does not match it acts on relays 30 and 31 blocking the operation of the supplier 21.
Esta estructura permite introducir un código de seguridad a través del teclado 10, que es almacenado en la memoria 8, con lo que sí durante el tiempo de temporización se introduce el código de seguridad, a través del teclado 10, la memoria 8 genera una señal para el detector de manipulación 14 el cual actúa sobre el circuito de corte de la siguiente forma:This structure allows you to enter a security code through the keyboard 10, which is stored in the memory 8, so if during the time of delay the security code is entered, through the keyboard 10, the memory 8 generates a signal for the manipulation detector 14 which acts on the cutting circuit as follows:
Si los relés 30 tenían cortada la alimentación de la bomba 22, efectúa la conexión de la alimentación de la misma.If the relays 30 had the power supply to the pump 22 cut off, it connects the power supply to the pump.
Si los relés 30 mantenían en funcionamiento al dispositivo precintado, y se introduce el código de seguridad durante el tiempo de temporización, se impide el corte de la alimentación de la bomba 22.If the relays 30 kept the sealed device running, and the security code is entered during the time of timing, the power cut of the pump 22 is prevented.
Además, cuando se efectúa el cierre de la tapa, no se ponen en funcionamiento los circuitos incluidos en la caja 27 hasta que no transcurre el tiempo temporizado.In addition, when the lid is closed, the circuits included in the box 27 are not operated until the timed time elapses.
Igualmente, si se abre y cierra la tapa sin que se introduzca el código de seguridad, se produce el corte de la alimentación de la bomba 22 y del encoder. Likewise, if the lid is opened and closed without entering the security code, the power supply to the pump 22 and the encoder is cut.
