Abstract

EN UN SISTEMA DE CONTROL REMOTO BIDIRECCIONAL, VARIOS APARATOS, INCLUYENDO LA UNIDAD MANUAL, INCLUYEN UN TRANSMISOR Y TAMBIEN UN RECEPTOR. EL RECEPTOR DE LA UNIDAD VA ALIMENTADO POR PILAS. DADO QUE ESTE RECEPTOR TIENE QUE ESTAR CONSTANTEMENTE EN ESTADO OPERATIVO, LA PILA SE AGOTA CON MUCHA RAPIDEZ. PARA SUPERAR ESTO HAN SIDO SELECCIONADOS TRANSMISORES QUE EMITEN MENSAJES DE UN TIPO PARTICULAR. DE HECHO, CADA MENSAJE CONSTA DE UNA SERIE DE IMPULSOS Y EL COMIENZO DE CADA UNO ESTA PRECEDIDO POR UN IMPULSO DE ACTIVACION. AL MENOS EL RECEPTOR ALIMENTADO POR PILA TIENE UN CIRCUITO DE DETECCION DE IMPULSOS DE ACTIVACION QUE CONTROLA UN CIRCUITO CONMUTADOR QUE HACE PASAR AL RECEPTOR DEL ESTADO DE REPOSO AL ESTADO OPERATIVO TRAS RECIBIR UN IMPULSO DE ACTIVACION Y QUE LO DEVUELVE AL ESTADO DE REPOSO POSTERIORMENTE, ESTADO EN EL QUE CONSUME MUY POCA ENERGIA SI DURANTE UN CIERTO PERIODO NO SE HA RECIBIDO NINGUN IMPULSO DE ACTIVACION.
