RADIO FREQUENCY ANTI-THEFT SYSTEM DESCRIPTION The object of the present invention is an anti-theft system based on a radio frequency (RF) device that is jointly and severally connected to the object to be protected. Said RF device emits every t seconds an encrypted signal that is received by a central receiving element, which has limited coverage to the specific protected enclosure and where it can be displayed at all times that the object is protected.
ESTADO DE LA TÉCNICA ANTERIOR STATE OF THE PREVIOUS TECHNIQUE
El hurto en los comercios minoristas es uno de los mayores problemas a los que se enfrentan en su labor diaria. Para solucionar este problema el estado actual de la técnica describe múltiples sistemas. Theft in retail stores is one of the biggest problems they face in their daily work. To solve this problem, the current state of the art describes multiple systems.
Así pues, el estado de la técnica más cercano a la presente invención es el señalado en el documento ES 2 239 489 describe un sistema electrónico de vigilancia activa de artículos basado en el empleo de un doble etiquetado inteligente de seguridad que se caracteriza porque además de la convencional etiqueta externa aplicada a cada artículo se incluye una etiqueta de seguridad electrónica interna que incorpora un circuito integrado dotado de memoria no volátil cuya información será, al menos, la misma información que lleve impresa la etiqueta convencional externa y capaz asimismo de responder con dicha información ante un interrogador electrónico RFID dispuesto en el lugar adecuado. El sistema tiene capacidad de detectar intentos de sustracción mediante la comparación de ambas informaciones y avisar en tiempo real del artículo causante de la incidencia, así como de su posición. EXPLICACIÓN DE LA INVENCIÓN Thus, the state of the art closest to the present invention is that indicated in document ES 2 239 489 describes an electronic system for active article surveillance based on the use of a double intelligent security labeling characterized in that in addition to The conventional external label applied to each article includes an internal electronic security label that incorporates an integrated circuit equipped with non-volatile memory whose information will be, at least, the same information that is printed on the external conventional label and also capable of responding with said Information before an RFID electronic interrogator in the right place. The system has the ability to detect subtraction attempts by comparing both information and notify in real time of the article causing the incident, as well as its position. EXPLANATION OF THE INVENTION
Es un objeto de la presente invención un sistema antirrobo basado en un dispositivo por radio frecuencia (RF) que se encuentra solidariamente unido al objeto a proteger. Dicho dispositivo de RF emite cada t segundos una señal cifrada que es recibida por un elemento receptor central, el cual tiene una cobertura limitada al entorno de actuación (centro comercial, museo, edificio, ...) específico protegido y en donde se puede visualizar en todo momento que el objeto está protegido.
Cuando dicho objeto, con su emisor, que es el dispositivo RF, desaparecen de la cobertura proporcionada por la antena que hay en el local, saltará una alarma, evitando los problemas de los actuales sistemas antirrobo, tal y como ha sido indicado para el estado de la técnica, en donde con una simple "Jaula de Faraday" es posible el hurto o robo del objeto, dado que son sistemas preferentemente de tipo magnético. An object of the present invention is an anti-theft system based on a radio frequency (RF) device that is integral with the object to be protected. Said RF device emits every t seconds an encrypted signal that is received by a central receiving element, which has a limited coverage to the specific operating environment (shopping center, museum, building, ...) and where it can be displayed at all times that the object is protected. When said object, with its emitter, which is the RF device, disappears from the coverage provided by the antenna in the premises, an alarm will go off, avoiding the problems of the current anti-theft systems, as indicated for the state of the technique, where with a simple "Faraday cage" theft or theft of the object is possible, since they are preferably magnetic type systems.
La comunicación entre el emisor y el objeto a proteger se verifica cada t segundos, controlando de forma efectiva el objeto. Además, en otro aspecto de la invención, los dispositivos emisores de RF no solo emiten una señal que podemos denominar plana, sino que comunican de qué objeto se trata (codificado en la señal RF), siendo por tanto fácilmente identificable la sección, planta y, en general cualquier información que facilite su localización. The communication between the emitter and the object to be protected is verified every t seconds, effectively controlling the object. In addition, in another aspect of the invention, the RF emitting devices not only emit a signal that we can call flat, but also communicate which object it is (encoded in the RF signal), thus the section, plant and , in general any information that facilitates its location.
El dispositivo emisor de RF cuenta con un interruptor, de tal forma que se evite el conocido como tampering, es decir, evitar que abran el dispositivo de RF para el hurto del objeto. The RF emitting device has a switch, in such a way that the one known as tampering is avoided, that is, preventing them from opening the RF device for theft of the object.
El sistema así descrito, por tanto, no sólo previene el robo, sino que además, advierte del intento, puesto que la alarma se activa en cuanto pierde la señal el emisor con el receptor, lo cual suele ocurrir en el propio recinto. The system thus described, therefore, not only prevents theft, but also warns of the attempt, since the alarm is activated as soon as the sender loses the signal with the receiver, which usually occurs in the premises itself.
En una realización particular, el dispositivo emisor incorpora un inclinómetro o un acelerómetro, de tal forma que pueda ser empleado en objetos que no deben ser movidos, como cuadros en museos, y ser empleadas las señales de estos elementos como criterio adicional de alarma. In a particular embodiment, the emitting device incorporates an inclinometer or an accelerometer, so that it can be used on objects that should not be moved, such as paintings in museums, and the signals of these elements be used as an additional alarm criterion.

Thus, each of the emitters (100) releases an encrypted periodic signal (every t seconds, programmable by the end user) by a spread spectrum technique, which is a technique known in the art, where an RF signal is multiplexed in a plurality of RF channels to prevent signal inhibition.
Dicha señal comprenderá, al menos, un código de identificación para cada recinto determinado (300) y el código del producto protegido, de tal forma que la combinación de ambos impide que el solapamiento entre coberturas ofrezca problemas o genere interferencias. Said signal will comprise, at least, an identification code for each determined enclosure (300) and the code of the protected product, so that the combination of both prevents the overlap between coverage offers problems or generates interference.

Dicho dispositivo comprende una unidad central de control (1) que además comprende un elemento de memoria para almacenar y reprogramar los datos del dispositivo, facilitando su reutilización. Dicha reprogramación puede hacerse, bien porque el dispositivo (100) tenga capacidad emisora - receptora, bien mediante un puerto de comunicaciones serie (5) previsto a tal efecto y propósito. La unidad central de control (1) gestiona la emisión de la señal de RF (2), de tal forma que emita dicha señal cada t segundos, provocando una alarma en el caso de que no emita la señal cada periodo programado, tanto en el receptor (200) como en el emisor

The central control unit (1) manages the emission of the RF signal (2), in such a way that it emits this signal every t seconds, causing an alarm in the event that the signal is not emitted every programmed period, both in the receiver (200) as in the transmitter (100)
La unidad central de control (1) igualmente gestiona el dispositivo de control de apertura (4), que en una realización particular puede ser un dispositivo óptico, y medios propios de alarma (3), de tal forma que cada dispositivo (100) además de alertar al receptor central de RF (200) pueda emitir su propia señal de alarma. The central control unit (1) also manages the opening control device (4), which in a particular embodiment can be an optical device, and own alarm means (3), such that each device (100) also of alerting the central RF receiver (200) can emit its own alarm signal.
