Description
Sistema de localización de vehículos en interiores.Vehicle tracking system in interiors
La mayor parte de los Servicios Públicos, (Policía, Bomberos, Ambulancias, Servicios de transporte público) disponen de sistemas de gestión y localización de flotas basados en tecnologías de localización por satélite GPS, o Sistema de Posicionamiento Global. En este sentido, cobra gran importancia dotar de cobertura GPS en el interior de los túneles de carreteras para que, ante emergencias, los vehículos de los Servicios Públicos puedan estar localizados en todo momento y lugar.Most of the Public Services, (Police, Fire, Ambulance, Public transport services) They have fleet management and location systems based on GPS satellite tracking technologies, or System Global Positioning In this sense, it becomes very important provide GPS coverage inside road tunnels so that, in emergencies, the Public Services vehicles They can be located at any time and place.
Además, esta medida redunda también en beneficio de la gran cantidad de ciudadanos que disponen de navegadores comerciales (GPS) que se han convertido en imprescindibles tanto para su trabajo diario como para su tiempo de ocio.In addition, this measure also benefits of the large number of citizens who have browsers commercials (GPS) that have become indispensable both for your daily work as for your leisure time.
En la actualidad existen numerosos métodos para la inserción de señales en el interior de túneles, como puede ser la utilización de cable radiante, pero la necesidad de inyectar diferentes señales en función de las coordenadas invalida este tipo de soluciones convencionales, ya que el resultado de realizar una localización GPS sería el mismo para cualquier punto del túnel.There are currently numerous methods for the insertion of signals inside tunnels, such as the use of radiant cable, but the need to inject different signals depending on the coordinates invalidates this type of conventional solutions, since the result of making a GPS location would be the same for any point of the tunnel.

Se trata de un sistema muy sencillo que trabaja con señales reales GPS para situar los vehículos en interiores. La solución expuesta consiste en la inyección de la señal GPS a intervalos regulares en el interior del túnel. Ningún sistema existentes realiza lo que la presente invención, que es inyectar en tiempo real al interior del túnel la señal GPS auténtica recibida de los satélites por las antenas exteriores, a través de amplificadores, a las distintas antenas interiores separadas regularmente, con lo que los vehículos dentro del túnel reciben señales auténticas GPS en tiempo real. Cada antena interior presenta un radio de cobertura dentro del cual la posición GPS leída por los receptores permanece constante, siendo ésta igual a la recibida por la antena GPS exterior. De esta forma, un receptor que se desplace por el interior del túnel irá recibiendo diferentes posiciones GPS según avance pasando de la zona de cobertura de una antena a la siguiente. La precisión en el posicionamiento del receptor GPS en el interior del túnel estará condicionada por el número de antenas GPS instaladas y por la separación entre las mismas. El receptor GPS captará a lo largo del túnel tantas posiciones diferentes como conjuntos de antena exterior/antena interior existan a lo largo de su recorrido.It is a very simple system that works with real GPS signals to place vehicles indoors. The exposed solution involves the injection of the GPS signal to regular intervals inside the tunnel. No system existing realizes what the present invention, which is to inject into real time inside the tunnel the authentic GPS signal received from the satellites through the external antennas, through amplifiers, to the different separate indoor antennas regularly, with what the vehicles inside the tunnel receive authentic GPS signals in real time. Each indoor antenna presents a coverage radius within which the GPS position read by the receivers remain constant, this being equal to that received by The outdoor GPS antenna. In this way, a receiver that moves inside the tunnel you will receive different GPS positions as it progresses from the coverage area of an antenna to the next. The accuracy in the positioning of the GPS receiver in the Inside the tunnel will be conditioned by the number of GPS antennas installed and by the separation between them. GPS receiver will capture along the tunnel as many different positions as outdoor antenna / indoor antenna assemblies exist along its route.
En la figura 1 se representa un esquema de la solución propuesta, donde se aprecian unos vehículos dentro de un túnel, unos satélites GPS y los equipos que conforman esta solución. La figura 2 amplía una parte de la figura 1, resaltando la configuración de cada uno de esos equipos. La figura 3 es un diagrama real de dos túneles con un tercer túnel de servicio que une ambos y un pozo de ventilación y emergencia.A schematic of the proposed solution, where you can see some vehicles within a tunnel, GPS satellites and the equipment that make up this solution. Figure 2 enlarges a part of Figure 1, highlighting the configuration of each of those teams. Figure 3 is a real diagram of two tunnels with a third service tunnel linking both and a ventilation and emergency well.
El sistema se basa en la inyección de la señal GPS a intervalos regulares en el interior del túnel. Cada antena interior presenta un radio de cobertura dentro del cual la posición GPS leída por los receptores permanece constante, siendo ésta igual a la recibida por la antena GPS exterior. De esta forma, un receptor que se desplace por el interior del túnel irá recibiendo diferentes posiciones GPS según avance pasando de la zona de cobertura de una antena a la siguiente, tal como se esquematiza en la figura 1.The system is based on signal injection GPS at regular intervals inside the tunnel. Each antenna interior has a coverage radius within which the position GPS read by the receivers remains constant, this being the same to that received by the external GPS antenna. In this way, a receiver that travels inside the tunnel will receive different GPS positions as you move past the coverage area of a antenna to the next, as outlined in Figure 1.
Los componentes del sistema, tal como se representa en la figura 2, son: antenas externas que captan las señales de los satélites (1), antenas interiores colocadas en los techos de los túneles (3) y amplificadores (2) que retransmiten las señales desde las primeras a las segundas. La precisión en el posicionamiento del receptor GPS en el interior del túnel estará condicionada por el número de antenas GPS instaladas y por la separación entre las mismas. El receptor GPS captará a lo largo del túnel tantas posiciones diferentes como conjuntos de antena exterior/antena interior existan a lo largo de su recorrido.System components, as is represented in figure 2, are: external antennas that capture the signals from satellites (1), interior antennas placed in the roofs of the tunnels (3) and amplifiers (2) that relay the signals from the first to the second. The precision in the GPS receiver positioning inside the tunnel will be conditioned by the number of GPS antennas installed and by the separation between them. The GPS receiver will pick up along the tunnel as many different positions as antenna sets outdoor / indoor antenna exist along its path.
Si la disposición final de las antenas no fuera totalmente equidistante no se dispondría de una localización tan exacta de todos los puntos del recorrido, pero se dispone de suficiente información para determinar la localización de los vehículos en cuanto a su sentido, marcha o tramo de la carretera en el que se encuentran, puesto que en el momento en el que un vehículo abandone un radio de localización entrará en el siguiente. El número definitivo de conjuntos y su separación estará sujeto a diferentes factores como pueden ser: características constructivas del interior de los túneles y su influencia en la propagación de la señal, situación de los pozos y canalizaciones que comuniquen el exterior con el interior de los túneles, distancias de cableado entre antenas, posibilidades de montaje de las antenas, etc.If the final arrangement of the antennas were not totally equidistant would not have such a location exact of all the points of the route, but it has enough information to determine the location of vehicles in terms of their direction, gear or section of the road in the one they meet, since at the moment when a vehicle leave a location radius will enter the next one. The number final sets and their separation will be subject to different factors such as: construction characteristics of the interior of tunnels and their influence on signal propagation, situation of wells and pipelines that communicate abroad with the inside of the tunnels, wiring distances between antennas, mounting possibilities of the antennas, etc.
La instalación de las antenas es permanente y muy sencilla contando con las canalizaciones y accesorios preinstalados. En la figura 3 se ha representado un túnel real, que normalmente está compuesto de dos túneles, uno para cada sentido de marcha, un tercer túnel de servicio que une ambos y un pozo de ventilación y emergencia. En la parte exterior del túnel se instalan las antenas exteriores (1), las cuales son activas y reciben la señal GPS en tiempo real.The installation of the antennas is permanent and very simple with the pipes and accessories preinstalled In Figure 3 a real tunnel has been represented, which It is usually composed of two tunnels, one for each direction of march, a third service tunnel that joins both and a well of ventilation and emergency. On the outside of the tunnel they are installed the external antennas (1), which are active and receive the GPS signal in real time.
Los amplificadores de la señal GPS (2), de bajo ruido y ancho de banda el de la señal GPS, permiten la inyección la inyección de dicha señal y se pueden instalar, en el modo de realización que explicamos, dentro de los túneles de servicio, aunque se pueden instalar en cualquier otro lugar adecuado; su ganancia es a determinar en cada caso y se calcula en función de la potencia de emisión necesaria en cada antena.Amplifiers of the GPS signal (2), low noise and bandwidth of the GPS signal, allow injection the injection of said signal and can be installed, in the mode of realization that we explain, within the service tunnels, although they can be installed in any other suitable place; its profit is to be determined in each case and is calculated based on the emission power needed in each antenna.
Las antenas interiores (3) también son activas y emiten la señal GPS en tiempo real, con una potencia de emisión que varia según su alcance. Esta potencia se calcula estableciendo que en el punto de solape entre la señal de dos antenas adyacentes el nivel de señal sea óptimo.The inner antennas (3) are also active and they emit the GPS signal in real time, with an emission power that It varies according to its scope. This power is calculated by establishing that at the point of overlap between the signal of two adjacent antennas the signal level is optimal.
Los cables entre antena interior y amplificador intermedio y amplificador intermedio y antena exterior deben tener pérdidas muy bajas.The cables between indoor antenna and amplifier intermediate and intermediate amplifier and outdoor antenna must have very low losses
Como es lógico es necesario prever unos medios para la alimentación de los amplificadores (4), los cuales pueden proporcionar la energía necesaria, bien desde el túnel de servicio, bien a través del pozo de ventilación y emergencia.Of course it is necessary to provide some means for powering the amplifiers (4), which can provide the necessary energy, either from the service tunnel, well through the ventilation and emergency well.
Es necesario establecer un vado de entre 2 y 8 metros entre 2 antenas transmisoras con el fin de evitar el solape entre las señales. En cada caso se establecerá el vado necesario para el correcto funcionamiento del sistema.It is necessary to establish a ford between 2 and 8 meters between 2 transmitting antennas in order to avoid overlap Between the signals In each case the necessary ford will be established for the correct functioning of the system.
Una vez efectuada la instalación, la puesta en marcha se realiza de forma rápida, puesto que la arquitectura del sistema permite intercambiar las piezas que se desee y el único ajuste posible reside en la elección de los amplificadores (potencia) y antenas emisoras (directivas u omnidireccionales) adecuadas para radiar la señal de manera uniforme y sin solapamientos.Once the installation has been carried out, commissioning gait is done quickly, since the architecture of the system allows to exchange the desired pieces and the only one possible adjustment lies in the choice of amplifiers (power) and transmitting antennas (directive or omnidirectional) suitable to radiate the signal evenly and without overlaps.
Conviene insistir en que esta solución es para detección de la posición de vehículos en interiores o zonas sin cobertura GPS, por lo que su uso no se limita a túneles, sino que también se utiliza en aparcamientos cubiertos o interiores, garajes, cocheras de autobuses y camiones y locales de cualquier tipo que no tengan la suficiente cobertura de señales GPS.It is important to insist that this solution is for detection of the position of vehicles in interiors or areas without GPS coverage, so its use is not limited to tunnels, but It is also used in covered or indoor parking, garages, bus and truck garages and premises of any kind that do not have sufficient coverage of GPS signals.
