Abstract

Para determinar la velocidad de carros de ferrocarril por medio de informadores de resultados fijos en el lugar se han utilizado hasta el presente los flancos delanteros de los informadores de resultados. Aquí pueden las ruedas del vehículo que proporcionan las informaciones de los resultados presentar un desplazamiento lateral con respecto a los rieles entre 0 y 70 mm. En dependencia de este desplazamiento lateral varía el campo o región de actividad del informador de resultado, de manera que se producen diferentes tiempos de medición de los informadores en dependencia del desplazamiento lateral de las ruedas del vehículo junto a los informadores de resultados. Esto conduce a valores de velocidad inexactos. De acuerdo con el procedimiento de la presente invención no se utiliza un flanco determinado del informador de resultados para la determinación de la velocidad sino los promedios de impulso correspondientes; los valores de medición encontrados son así independientes de las tolerancias de respuesta del informador o registrador de resultados.Up to the present time, the front flanks of the result reporters have been used to determine the speed of rail cars by means of fixed results reporters on site. Here the wheels of the vehicle that provide the results information can present a lateral displacement with respect to the rails between 0 and 70 mm. Depending on this lateral displacement, the field or region of activity of the result reporter varies, so that different measurement times of the reporters occur depending on the lateral displacement of the wheels of the vehicle together with the result reporters. This leads to inaccurate speed values. According to the method of the present invention, a determined edge of the result reporter is not used for the determination of the speed, but the corresponding impulse averages; the measured values found are thus independent of the response tolerances of the informant or recorder of results.
