The invention deals with an electronic system for radio frequency identification of the presence or absence of known active objects, padlocks with their keys or potentially dangerous energy isolation devices, within at least one container belonging to at least one cabinet or module or the like, by associating the object to a radio frequency identification tag (REID), where a controller indicates the number of active objects, ID corresponding to each tag (REID) and in which specific container they are found, which It allows the protection and restriction of access to the key(s) of the padlock(s) or potentially dangerous energy isolation devices for people who intervene in machines, equipment, circuits or electrical, pneumatic, hydraulic, kinetic or potential systems.
La identificación por radio frecuencia, es un sistema de almacenamiento y recuperación de datos remotos que usa dispositivos denominados etiquetas, tarjetas transpondedores REID. El propósito fundamental de la tecnología REID es transmitir la identidad de un objeto (similar a un número de serie único) mediante ondas de radio. Las tecnologías REID se agrupan dentro de las denominadas Auto ID (identificación automática). Radio frequency identification is a remote data storage and retrieval system that uses devices called tags, REID transponder cards. The fundamental purpose of REID technology is to transmit an object's identity (similar to a unique serial number) via radio waves. REID technologies are grouped within the so-called Auto ID (automatic identification).
Las etiquetas de identificación por radio frecuencia son unos dispositivos pequeños, similares a una pegatina, que pueden ser adheridas o incorporadas a un producto, un animal o una persona. Contienan antenas para permitirles recibir y responder a peticiones por radiofrecuencia desde un emisor receptor REID. Las etiquetas pasivas no necesitan alimentación eléctrica interna, mientras que las activas sí lo requieren. Una de las ventajas del uso de radiofrecuencia (en lugar, por ejemplo, de infrarrojos) es que no se requiere visión directa entre emisor y receptor. Radio frequency identification tags are small, sticker-like devices that can be affixed to or attached to a product, an animal or a person. They contain antennas to allow them to receive and respond to RF requests from a REID receiver. Passive tags do not need internal power supply, while active tags do. One of the advantages of using radio frequency (instead of, for example, infrared) is that direct line of sight between transmitter and receiver is not required.

Descripción de la Invención Description of the Invention
En atención a las figuras 1 a 5, la invención para sistema electrónico de identificación por radio frecuencia de la presencia o ausencia de objetos activos conocidos, como candados o dispositivos de aislamiento de energía potencialmente peligrosas (1,) dentro de un gabinete, módulo o lo similar (2), el cual está conformado con una estructura de soporte principal (3), con un contenedor superior (4) y un contenedor inferior (5). In attention to figures 1 to 5, the invention for an electronic system for radio frequency identification of the presence or absence of known active objects, such as padlocks or potentially dangerous energy isolation devices (1,) inside a cabinet, module or the similar (2), which is made up of a main support structure (3), with an upper container (4) and a lower container (5).
Entre el contenedor superior (4) y el contenedor inferior (5), se ubican al menos dos antenas de identificación por radio frecuencia UHF (6) , las cuales se encuentran dispuestas en forma paralelas y presentan en una de sus caras, un área que proyecta un haz de lectura campo electromagnético, similar a un haz de luz. que establece un volumen limitado de lectura hacia el interior superior e inferior del gabinete o módulo (2), siendo dicho haz de lectura de proyección superior (7) de configuración longitudinal cónico invertido y el haz de iluminación de proyección inferior (8), es de configuración longitudinal cónico, donde dicha proyección superior e inferior del haz de lectura de campo electromagnético, permiten la lectura de la presencia o ausencia de unas etiquetas de identificación por radiofrecuencia (9) con su asociación de objetos activos, como candados o dispositivos de aislamiento de energía potencialmente peligrosas (1.) Las antenas de identificación por radio frecuencia (6), en este caso, puede leer hasta treinta etiquetas de identificación por radio frecuencia (9) de forma simultánea; dependiendo de las dimensiones y la potencia de las antenas de identificación por radio frecuencia UHF (6) . estas pueden leer mayor o menor cantidad de etiquetas de identificación por radio frecuencia (9). Between the upper container (4) and the lower container (5), at least two UHF radio frequency identification antennas (6) are located, which are arranged in parallel and present on one of their faces, an area that projects an electromagnetic field reading beam, similar to a light beam. which establishes a limited reading volume towards the upper and lower interior of the cabinet or module (2), said projection reading beam being upper (7) of inverted conical longitudinal configuration and the lower projection lighting beam (8), is of conical longitudinal configuration, where said upper and lower projection of the electromagnetic field reading beam, allow the reading of the presence or absence of some radio frequency identification tags (9) with their association of active objects, such as padlocks or potentially dangerous energy isolation devices (1.) The radio frequency identification antennas (6), in this case, can read up to thirty tags radio frequency identification (9) simultaneously; depending on the dimensions and power of the UHF radio frequency identification antennas (6). these can read a greater or lesser number of radio frequency identification tags (9).
La frecuencia de funcionamiento de las antenas UHF (6) dependiendo de las regulaciones de frecuencia de cada país, existen tres rangos de frecuencias: 902- 928Mhz para Estados Unidos (US/FCC), 8B5-8B8Mhz para Europa (EU/ETSI ) y 8B0- OBOMhz que es el rango global, de manera que para la lectura de dichas etiqueta de radio frecuencia (9), el interior de los contenedores (4) y (5) deben estar revestidos con un material de plástico u otro material no metálico; invisibles o transparentes para el haz de lectura generado por las antenas, por lo que los materiales metálicos del gabinete o módulo (2) son una barrera que reflejan, bloquean o interrumpen el haz de lectura de las antenas para la identificación por radio frecuencia UHF(6) , impidiendo la lectura de las etiquetas de identificación por radio frecuencia (9) de los objetos asociados a los candados o dispositivos de aislamiento de energía potencialmente peligrosas (1) en las zonas que están fuera de los contenedores (4) y (5). Las etiquetas de identificación por radio frecuencia (9), no necesitan energía para poder ser leídas, la lectura de dicha etiqueta de radio frecuencia (9) es posible mediante el estímulo generado por las antenas de identificación por radio frecuencia UHF (5). razón por la cual, es muy importante la ubicación, tanto de las antenas de identificación por radio frecuencia UHF (6) como también de las etiquetas de identificación por radiofrecuencia (9) en tiempo y lugar precisos para su lectura. The operating frequency of the UHF antennas (6) depending on the frequency regulations of each country, there are three frequency ranges: 902-928Mhz for the United States (US/FCC), 8B5-8B8Mhz for Europe (EU/ETSI) and 8B0- OBOMhz, which is the global range, so that in order to read said radio frequency tag (9), the inside of the containers (4) and (5) must be lined with a plastic material or other non-metallic material ; invisible or transparent to the reading beam generated by the antennas, so the metallic materials of the cabinet or module (2) are a barrier that reflect, block or interrupt the reading beam of the antennas for UHF radio frequency identification ( 6), preventing the reading of the radio frequency identification labels (9) of the objects associated with padlocks or potentially dangerous energy isolation devices (1) in the areas outside the containers (4) and (5 ). The radio frequency identification tags (9) do not need energy to be read, the reading of said radio frequency tag (9) is possible by means of the stimulus generated by the UHF radio frequency identification antennas (5). For this reason, the location of both the UHF radio frequency identification antennas (6) and the radio frequency identification labels (9) at the precise time and place for their reading is very important.
Cada etiqueta de identificación por radio frecuencia (9), posee de fábrica un identificador único, de solo lectura, no es posible cambiar el identificador único. Each radio frequency identification tag (9) has a unique, read-only identifier from the factory; it is not possible to change the unique identifier.
