Los inicios de la tecnología Bluetooth datan de 1994, cuando la compañía de comunicaciones Ericsson Mobile Communications promovió una iniciativa para estudiar una interfaz por radio entre los teléfonos móviles y sus accesorios, con bajo coste y bajo consumo. Hasta entonces las opciones para comunicar los móviles y sus accesorios eran las tecnologías de comunicaciones basadas en el cable, que funcionaban con eficiencia pero cuya instalación y configuración resultaba bastante engorrosa, y los infrarrojos, que tampoco resultan muy adecuados ya que se necesita línea de visión directa entre los dispositivos a comunicar. A partir de aquí, se promovió la definición de un estándar para que el uso de esta tecnología se popularizara y fuera posible la interconexión entre dispositivos de diferentes fabricantes.The beginnings of Bluetooth technology date back to 1994, when the communications company Ericsson Mobile Communications promoted an initiative to study a radio interface between mobile phones and their accessories, with low cost and low consumption. Until then, the options for communicating mobile phones and their accessories were cable-based communications technologies, which worked efficiently but whose installation and configuration was quite cumbersome, and infrared, which are not very suitable either since line of sight is needed Direct between the devices to communicate. From here, the definition of a standard was promoted so that the use of this technology became popular and interconnection between devices of different manufacturers was possible.
El ámbito de utilización de Bluetooth ha ido extendiéndose y no sólo se piensa en él para la comunicación entre un móvil y sus accesorios, sino que también ofrece la posibilidad de eliminar los molestos cables que se utilizan en el ordenador. Hoy en día el uso de teclados y ratones inalámbricos, impresoras, etc., está cada vez más extendido. Otros dispositivos que están teniendo gran aceptación son los manos libres para los teléfonos móviles, etc.The scope of use of Bluetooth has been extended and not only thought about it for communication between a mobile and its accessories, but also offers the possibility of eliminating the annoying cables used in the computer. Today the use of wireless keyboards and mice, printers, etc., is increasingly widespread. Other devices that are having great acceptance are hands-free for mobile phones, etc.
La extensión de la utilización de la tecnología Bluetooth a otros entornos fuera de la mera interconexión de dispositivos la podemos ver en ejemplos como sistema para control horario de aparcamiento (ES 2191570), dispositivo aplicable a medidores de fluidos y energía doméstica para envío de datos de consumo (ES 1053684) y dispositivo de teleasistencia (ES 1057175).The extension of the use of Bluetooth technology to other environments outside the mere interconnection of devices can be seen in examples as a system for parking time control (ES 2191570), a device applicable to fluid meters and domestic energy for sending data from consumption (ES 1053684) and telecare device (ES 1057175).
Ejemplos próximos de la aplicación de la tecnología Bluetooth en la difusión de información multimedia (por ejemplo, publicidad) se encuentran en los documentos WO 02/19053, WO 2004/012420, WO 2004/100032, o WO2005/101863, aunque ninguno de los sistemas propuestos es alimentado por energía solar.Next examples of the application of Bluetooth technology in the dissemination of multimedia information (eg advertising) are found in WO documents 02/19053, WO 2004/012420, WO 2004/100032, or WO2005 / 101863, although none of the proposed systems is powered by solar energy.

Maneras de realización de la invenciónWays of carrying out the invention
A continuación se un ejemplo de realización preferente, no limitativo, de la invención que comprendería los siguientes elementos o componentes:Below is an example of a preferred, non-limiting embodiment of the invention that would comprise the following elements or components:
a) Panel solar de 10 W: Un panel fotovoltaico que suministra una potencia máxima de 10 W, a pleno rendimiento. Estos 10 W se utilizarán para cargar la batería, de acuerdo al esquema de la figura 6. b) Circuito de carga de la batería y protector del panel solar: circuito basado en diodos de silicio de potencia, como puede verse en la figura 6, que cumplen una doble misión: i. Evitar que la batería se descargue a través del panel solar, ii. Conseguir una carga de la batería a corriente constante. Este tipo de carga es el adecuado en baterías como la empleada [ver (f)] de plomo-acido para aprovechar al máximo el número de cargas/descargas. c) Programador: reloj programador horario/semanal, para controlar el arranquea) 10 W solar panel: A photovoltaic panel that supplies a maximum power of 10 W, at full capacity. These 10 W will be used to charge the battery, according to the scheme in figure 6. b) Battery charging circuit and solar panel protector: circuit based on silicon power diodes, as can be seen in figure 6, that fulfill a double mission: i. Prevent the battery from discharging through the solar panel, ii. Get a constant current battery charge. This type of charge is suitable for batteries such as the one used [see (f)] of lead-acid to maximize the number of charges / discharges. c) Programmer: clock schedule / weekly, to control the start
/parada del transmisor, de forma que se puedan realizar programaciones independientes para cada día de la semana. d) Temporizador / controlador de parada: circuito que recibe la señal del reloj programador y que genera las señales de temporización necesarias hacia la placa de control, de forma que el arranque / parada del sistema se realice de forma controlada y correcta. Dicho circuito está diseñado utilizando un temporizador NE555 en configuración monoestable, excitado mediante la señal de 1 V disponible en la salida del programador, la cual se amplifica hasta un nivel de 5 V que requiere la entrada del temporizador NE555. Una vez que el circuito temporizador pasa su salida a nivel bajo, el conmutador diseñado utilizando un transistor de potencia NPN TIP41, corta la alimentación de todo el sistema. En este mismo circuito se incluye una pequeña batería de 1,2 V, 10 mA, de NiCd5 que alimenta el reloj programador para que no pierda la programación en caso de desconexión o descarga de la batería de 12 V 10 Ah que alimenta todo el sistema. Dicha batería de 1,2 V, es recargada a partir de la tensión de 5 V disponible en el circuito a través de un circuito con un diodo de silicio y una resistencia, que limitan la corriente de carga de la batería e impiden su descarga a través del circuito cargador (figura 4). e) Fuente de alimentación: circuito encargado de generar la tensión única de alimentación de 5 V de toda la electrónica del transmisor. Se trata de una fuente de alimentación conmutada, construida entorno al convertidor DC/DC integrado de tipo Buck a 52 KHz LM2576-5, el cual, como se puede ver en la figura 5, utiliza capacidades externas y un inductor de potencia externo. La utilización de una fuente conmutada permite disponer de un rendimiento energético mucho más alto que en el caso de tener una fuente lineal. El rendimiento energético del convertidor es muy importante, al estar el sistema alimentado mediante batería recargada con energía solar. f) Batería: acumulador de plomo-ácido de 12 V, 10 Ah sellado, lo que proporciona una autonomía de 40 horas aproximadamente sin que esta sea recargada. g) Circuito externo de carga de la batería: Al igual que en el caso del circuito de carga mediante el panel solar, se trata de un circuito con diodos de silicio, que a la vez que protege contra inversión de polaridad, proporciona una corriente de carga constante y evita que la batería pueda descargarse a través del cargador externo (figura/ stop of the transmitter, so that independent programming can be carried out for each day of the week. d) Timer / stop controller: circuit that receives the signal from the programmer clock and generates the necessary timing signals towards the control board, so that the system start / stop is carried out in a controlled and correct way. This circuit is designed using a NE555 timer in monostable configuration, excited by the 1 V signal available at the programmer's output, which is amplified to a level of 5 V that requires the input of the NE555 timer. Once the timer circuit passes its output at a low level, The switch designed using a NPN TIP41 power transistor cuts the power of the entire system. This same circuit includes a small 1.2 V, 10 mA NiCd 5 battery that powers the timer so you don't lose programming in case of disconnection or discharge of the 12 V 10 Ah battery that powers all the system. Said 1.2 V battery is recharged from the 5 V voltage available in the circuit through a circuit with a silicon diode and a resistor, which limit the charge current of the battery and prevent its discharge to through the charger circuit (figure 4). e) Power supply: circuit responsible for generating the single 5 V supply voltage of all transmitter electronics. It is a switched power supply, built around the integrated DC / DC converter of the Buck type 52 KHz LM2576-5, which, as can be seen in Figure 5, uses external capabilities and an external power inductor. The use of a switched source allows for a much higher energy efficiency than in the case of having a linear source. The energy efficiency of the converter is very important, since the system is powered by a battery recharged with solar energy. f) Battery: sealed 12V lead-acid accumulator, 10 Ah sealed, which provides an autonomy of approximately 40 hours without it being recharged. g) External battery charging circuit: As in the case of the charging circuit through the solar panel, it is a circuit with silicon diodes, which while protecting against polarity reversal, provides a current of constant charging and prevents the battery from being discharged through the external charger (figure
6). h) Placa de control: Se trata de un computador monoplaca embebido, con un procesador ARM-9 en el que se puede ejecutar un kernel reducido del sistema operativo Linux. La utilización de un computador monoplaca, y del sistema operativo Linux hace posible la implementación del software del transmisor mediante lenguajes de programación de alto nivel como C++ [ver (j)] , además de ser posible la implementación concurrente de procesos transmisores. De esta forma, se consigue una implementación multihebra de todo el sistema que optimiza el rendimiento del mismo y la velocidad de transmisión. Este computador dispone de puertos USB para la conexión de transmisores Bluetooth estándar USB, así como de un puerto ethernet, dos puerto serie, un puerto SPI, un puerto I2C, y varios puertos de entrada/salida programables desde los registros internos del microprocesador. Las diferentes hebras software que se ejecutan, en la placa de control hacen que esta placa realice varias funciones (figura 7). i) Transmisor Bluetooth: transmisor Bluetooth estándar con conexión USB. Debe estar soportado por el driver genérico de Linux. j) Capa software: Como se ha dicho, la placa de control está construida sobre un computador monoplaca en el que se ejecuta un sistema operativo Lima reducido. Además del sistema operativo, es necesaria una capa software que realice las siguientes tareas de forma concurrente (figura 3): i. Búsqueda de dispositivos Bluetooth al alcance ii. Envío de la baliza a aquellos dispositivos encontrados y permitidos iii. Comprobación de las señales del circuito temporizador descrito en (d): Como en todo sistema operativo, antes de parar la máquina, es necesario cerrar correctamente el sistema de ficheros. De otra forma, pueden perderse datos y/o el sistema de ficheros puede corromperse, con lo que todo el sistema quedaría inutilizado pendiente de mantenimiento, para la reparación del sistema de ficheros. Es por esto necesario, que antes de parar el computador, este cierre el sistema de ficheros. El cierre del sistema del sistema de ficheros se realiza cuando a través de uno de los puertos de entrada/salida del microprocesador se recibe la señal procedente del circuito temporizador/controlador de parada del sistema. iv. Gestión de la energía: A través de un puerto del microprocesador que contiene un convertidor AJO, se realiza un control de la tensión en el panel solar y de la tensión en la batería. Esto asegura que si el sistema está arrancado, la batería tendrá una carga por encima de un determinado umbral. k) Módulo GPS: Se trata de un módulo integrado receptor GPS con chipset6). h) Control board: This is an embedded single-board computer, with an ARM-9 processor in which a reduced kernel of the Linux operating system can be run. The use of a single-plate computer, and the Linux operating system makes it possible to implement the transmitter software through high-level programming languages such as C ++ [see (j)], in addition to being possible the concurrent implementation of transmitter processes. In this way, a multi-threaded implementation of the entire system is achieved that optimizes its performance and transmission speed. This computer has USB ports for connecting standard USB Bluetooth transmitters, as well as an ethernet port, two serial ports, an SPI port, an I2C port, and several input / output ports programmable from the internal microprocessor registers. The different software threads that run on the control board cause this board to perform several functions (figure 7). i) Bluetooth transmitter: standard Bluetooth transmitter with USB connection. It must be supported by the generic Linux driver. j) Software layer: As mentioned, the control board is built on a single-board computer in which a reduced Lima operating system is running. In addition to the operating system, a software layer is required to perform the following tasks concurrently (Figure 3): i. Search for Bluetooth devices within reach ii. Sending the beacon to those devices found and allowed iii. Checking the signals of the timer circuit described in (d): As in any operating system, before stopping the machine, it is necessary to properly close the file system. Otherwise, data may be lost and / or the filesystem may be corrupted, which would render the entire system unusable pending maintenance, for the repair of the filesystem. It is therefore necessary, that before stopping the computer, it closes the file system. The file system system is closed when the signal from the timer / controller circuit of the system is received through one of the microprocessor's input / output ports. iv. Energy management: Through a port of the microprocessor that contains an AJO converter, a control of the voltage in the solar panel and the voltage in the battery is carried out. This ensures that if the system is booted, the battery will have a charge above a certain threshold. k) GPS module: This is an integrated GPS receiver module with chipset
