PERFECCIONAMIENTOS EN MODULOS DE REPRESENTACION VISUAL DE INFORMACION PARA SISTEMAS DE REPRESENTACION VISUAL DE INFOR-MACION |
摘要 |
<p>A plug-in "universal" information display module for use in an information display system, e.g. a train describer system, of the kind in which all information to be displayed is multiplexed onto a data highway routed to all display locations. The heart of the module is a microprocessor which "listens" to the multiplexed messages on the data highway, selects for decoding only those containing the address of its location and produces a decoded message in the form of a two-dimensional matrix display format suitable for scanning to drive an L.E.D. matrix display panel. An address programming means is connected to an address input to the microprocessor so that a module is normally programmed with a location address at the time of connection to the data highway either by a manual operation or automatically upon mating of the plug connector.</p> |
