Abstract

Energy saving device for a computer work-station has a sensor for detecting the physical presence of a person in front of the computer and control the power consumption of the computer accordingly.

Description

Die Erfindung betrifft eine Vorrichtung entsprechend dem Oberbegriff des Anspruchs 1 zur Energieeinsparung am Computerarbeitsplatz.The The invention relates to a device according to the preamble of claim 1 for energy saving at the computer workstation.

Derzeitige Computerarbeitsplätze (Computer und Peripherie) bieten zeitgesteuerte Energiesparoptionen. Der Zeitpunkt des Eintreffens der Energiesparfunktion kann dabei in aller Regel frei definiert werden oder tritt, vor allem bei Peripheriegeräten, nach festen Herstellervorgaben ein.current Computer workstations (Computer and peripherals) offer timed power-saving options. The time of arrival of the energy saving function can usually freely defined or occurs, especially in peripheral devices fixed manufacturer specifications.

Die Energiesparoptionen erstrecken sich vom Abschalten einzelner Gerätekomponenten bis zur Abschaltung des kompletten Gerätes.The Energy saving options include shutting down individual device components until the shutdown of the complete device.

Hauptnachteil der derzeitigen Möglichkeiten Einfluss auf den Energieverbrauch eines Computerarbeitsplatzes zu nehmen ist die Festlegung über die Zeitschiene. Die Berücksichtung anderer Faktoren, wie zum Beispiel die Abschaltung eines Gerätes bei zu hohen Temperaturen, dienen nicht primär der Energieersparnis.main disadvantage the current possibilities influence to take on the energy consumption of a computer workstation is laying down over the timeline. The consideration other factors, such as the shutdown of a device when too high temperatures, are not primarily the energy savings.

Aufgabe der Erfindung ist es, den Energieverbrauch eines Computerarbeitsplatzes abhängig davon zu steuern, ob ein Benutzer sich physisch in der Nähe des Arbeitsplatzes befindet.task The invention is the power consumption of a computer workstation depending on it to control whether a user is physically close to the workplace located.

Diese Aufgabe wird durch die Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst.These The object is achieved by the device having the features of the claim 1 solved.

Da in vielen Fällen ein Computerarbeitsplatz abgeschaltet werden kann, sofern sich der Benutzer nicht am Arbeitsplatz befindet, stellt das URM ein großes Energieeinsparpotential dar. Befindet sich der Benutzer wieder am Arbeitsplatz, so werden die Geräte wieder aktiviert.There in many cases a computer workstation can be switched off, provided that the User is not in the workplace, the URM represents a great energy saving potential If the user is back at work, then the devices activated again.

Ein am Computermonitor angebrachter oder integrierte Sensor (Infrarot, Ultraschall, elektromagnetisch, induktiv, Chipkarte, optisch durch Laser oder Lichtschranke oder Video, Transponder, RFID, etc.), der über eine vorhandene Schnittstelle mit dem Computer verbunden ist, detektiert die physische Präsens des Benutzers.One computer mounted or integrated sensor (infrared, Ultrasonic, electromagnetic, inductive, chip card, optically through Laser or photocell or video, transponder, RFID, etc.), which has one existing interface is connected to the computer detected the physical presence of the User.

Wird kein Benutzer detektiert, so schaltet die Peripherie und/oder der Computer in einen Energiesparzustand oder schaltet ab. Wird der Benutzer wieder detektiert, so schalten die Geräte wieder ein.Becomes no user detected, then switches the periphery and / or the Computer in a power-saving state or turns off. Will the User detected again, the devices turn on again.
