Los circuitos Sense convierten la información y los eventos analógicos del mundo real en datos digitales adecuados para el procesamiento de la unidad de control digital (DCU). La Figura 9-1 muestra un ejemplo de utilización de un motor bajo control digital. Esta figura ilustra las posibilidades de los sensores sólo para un motor giratorio. Dependiendo de la aplicación y de las necesidades del sistema, un motor puede tener varios sensores para determinar el estado del motor, entre los que se incluyen:
Tensión de alimentación
Velocidad de giro
Par de salida
Actual
Fase de rotación
Temperatura
Los sensores se utilizan tanto para controlar el sistema como para monitorear su estado.
Figura 9-1. Sistemas de sensores en un motor
Hay sensores adecuados para todos estos monitores de rendimiento del motor.
Sensores para todo
Los sensores son la vía a través de la cual los fenómenos físicos del mundo real se representan mediante señales eléctricas equivalentes. En los sistemas embebidos, la información de los sensores se convertirá en datos digitales.
Muchos sistemas electrónicos antiguos utilizaban directamente la salida analógica de un sensor como parte de un sistema de control. Los sistemas modernos digitalizan principalmente ...
