TÍTULO TITLE
Un sistema para determinar el estado funcional de un instrumento sensor en forma remota, que comprende al menos un instrumento sensor, al menos un módulo transductor de variable física, al menos un transmisor de medición, y al menos un subsistema actuador que está conectado a una unidad de control remota; y método asociado A system for determining the functional status of a remote sensing instrument, comprising at least one sensing instrument, at least one physical variable transducer module, at least one measuring transmitter, and at least one actuating subsystem that is connected to a remote control unit; and associated method
CAMPO DE APLICACIÓN SCOPE
La presente invención pertenece al área de la industria del control y manejo de sensores de medición, de preferencia, sensores de medición de variables físicas, particularmente, corresponde a un sistema para determinar el estado funcional de un instrumento sensor en forma remota, sin necesidad de intervenir el instrumento sensor en su emplazamiento. The present invention belongs to the area of the control and management of measurement sensors industry, preferably physical variable measurement sensors, in particular, corresponds to a system for determining the functional state of a sensor instrument remotely, without the need for intervene the sensor instrument in its location.
ANTECEDENTES BACKGROUND
De manera general, un sensor está compuesto por dos módulos principales: un transductor de variable física, el cual corresponde al elemento básico de un instrumento sensor, capaz de convertir una magnitud física en otra magnitud, que suele ser una señal eléctrica; y un transmisor de la medición, que corresponde a un módulo encargado de amplificar y transmitir el valor medido por el transductor, ya sea hacia un dispositivo de despliegue de información o un sistema que procesará la variable medida con algún fin en particular. In general, a sensor is composed of two main modules: a physical variable transducer, which corresponds to the basic element of a sensor instrument, capable of converting a physical quantity into another quantity, which is usually an electrical signal; and a measurement transmitter, which corresponds to a module responsible for amplifying and transmitting the value measured by the transducer, either towards an information display device or a system that will process the measured variable for a particular purpose.
Por su naturaleza, algunos instrumentos sensores, una vez que son instalados en su emplazamiento definitivo, no son accesibles para efectuar un diagnóstico de su estado funcional. El hecho de que el transmisor del instrumento sensor esté entregando una medición, no garantiza que ésta corresponda a un valor real, ya que, por ejemplo, el transductor del sensor podría estar dañado. i By their nature, some sensor instruments, once they are installed in their final location, are not accessible to diagnose their functional status. The fact that the transmitter of the sensor instrument is delivering a measurement does not guarantee that it corresponds to a real value, since, for example, the sensor transducer could be damaged. i
HOJAS DE SUSTITUCIÓN (REGLA 26)
Es por esta razón que se han desarrollado diversas soluciones asociadas al diagnóstico del estado funcional de sensores de manera remota. SUBSTITUTE SHEETS (RULE 26) It is for this reason that various solutions associated with the diagnosis of the functional status of sensors have been developed remotely.
Por ejemplo, el documento US5686885 describe un sistema de seguridad que tiene una estación de control remoto y un sensor de prueba cuando el sistema de seguridad se encuentra en un modo de funcionamiento normal. El sensor se prueba mediante el accionamiento de un botón en el sensor. El accionamiento del botón genera una señal que indica que una prueba se ha llevado a cabo. A la generación tanto de una señal de alarma generada por la prueba y una señal que indica que una prueba ha sido realizada, el sistema de seguridad determina que la señal de alarma se generó por una prueba del sensor y no por la detección de condiciones de alarma por el sensor. For example, US5686885 describes a security system that has a remote control station and a test sensor when the security system is in a normal operating mode. The sensor is tested by actuating a button on the sensor. The button operation generates a signal indicating that a test has been carried out. Upon generation of both an alarm signal generated by the test and a signal indicating that a test has been performed, the safety system determines that the alarm signal was generated by a sensor test and not by the detection of conditions of sensor alarm
Otra solución es la que plantea el documento CN203323786, el cual describe un dispositivo de prueba para un sensor fotoeléctrico de tipo de correlación remota. El dispositivo de prueba comprende dos bogies de prueba montados sobre carriles de guía; cada bogie de prueba comprende un marco de bogie; una porción inferior del bastidor del bogie está provista de meditas; una parte superior del bastidor de bogie está provista de una plataforma de fijación de sensor ajustable; una pinza de fijación de sensor, una placa de alineación y un dispositivo de mira láser están dispuestos en la plataforma de fijación del sensor uno al lado del otro; la estructura del bogie está provista de una batería de almacenamiento y un convertidor de voltaje; y la batería de almacenamiento
suministra energía para que un sensor sea probado a través del convertidor de voltaje. Another solution is that proposed in document CN203323786, which describes a test device for a photoelectric sensor of remote correlation type. The test device comprises two test bogies mounted on guide rails; each test bogie comprises a bogie frame; a lower portion of the bogie frame is provided with meditations; an upper part of the bogie frame is provided with an adjustable sensor fixing platform; a sensor fixing clip, an alignment plate and a laser sight device are arranged on the sensor fixing platform side by side; the bogie structure is provided with a storage battery and a voltage converter; and storage battery It supplies power for a sensor to be tested through the voltage converter.
Estos dispositivos presentan problemas en cuanto a que dependen de elementos externos, por ejemplo, no siendo en su totalidad utilizados de manera remota, y por lo tanto, requieren que un operario esté en terreno, en el caso del primer documento, y por otro lado, que requieren de elementos de energización adicionales para suministrar energía al sistema de prueba, como el caso de la segunda solución descrita. These devices present problems in that they depend on external elements, for example, not being fully used remotely, and therefore, require that an operator be in the field, in the case of the first document, and on the other hand , which require additional energizing elements to supply power to the test system, as in the case of the second solution described.

SUMMARY OF THE INVENTION The present invention relates to a system for determining the functional state of a sensor instrument remotely, without the need to intervene the sensor instrument in its location.
La invención incorpora, ya sea, dentro del instrumento sensor, o en las cercanías de éste, un tercer módulo al que se llamará subsistema actuador. El subsistema actuador deberá ser tal que permita, mediante un requerimiento remoto, producir una variable física de la misma naturaleza que la medida por el transductor del instrumento sensor, la cual está activa durante el tiempo que sea requerido, con el fin de producir de manera artificial, un estímulo o conjunto de estímulos que deberían ser detectados por el módulo transductor del sensor, y cuya medición podrá ser evaluada en forma remota.
