Abstract
Description
Lichtintensitätsregler (Dimmer) für ScheinwerferLight intensity regulator (dimmer) for headlights
im Studio- und Biihnenbetrieb.in studio and stage operations.
Die Erfindung betrifft einen Lichtintensitätsregler (Dimmer) für Scheinwerfer größerer Leistung im Studio und BUhnenbetrieb. Herkömmliche bekannte Lichtintensitätaregler kennen nur eine analoge Kennliniennachbildung, so daß eine Kennlinienänderung nur durch eine komplette Neuentwicklung moglich ist.The invention relates to a light intensity regulator (dimmer) for headlights greater performance in the studio and stage operation. Conventionally known light intensity controls know only an analog characteristic curve simulation, so that a characteristic curve change only is possible through a completely new development.
Der Erfindung liegt die Aufgabe zugrunde, diesen Nachteil zu vermeiden und eine freiprogrammierbare Kennlinie zu schaffen, die kundenspezifische Wünsche und Erfordernisse berücksichtigt.The invention is based on the object of avoiding this disadvantage and to create a freely programmable characteristic curve that meets customer-specific requirements and requirements are taken into account.
Gelöst wird diese Aufgabe nach der Erfindung durch UmwandlSung der Eingangs sollwerte in die lichtlineare Kennlinie durch einen Mikrocomputer mit einem Mikroprozessor -etwa Z 80s, einem oder mehreren kleineren J/O port -etwa 8255- und einem Sample-and-Hold-Verstärker für die Ausgangssignale, wobei die analogen Eingangssollwerte in Zusammenarbeit mit der 7lerkömmlichen Peripherie softwaremäßig digitalisiert, tabellarisch in die lichtlineare Kennlinie umgesetzt und wieder analogisiert werden.This object is achieved according to the invention by converting the Input setpoints in the light linear characteristic curve by a microcomputer with a Microprocessor -about Z 80s, one or more smaller J / O ports -about 8255- and a sample-and-hold amplifier for the output signals, with the analog input setpoints digitized by software in cooperation with conventional peripherals, can be converted into the light-linear characteristic curve in the form of a table and then analogized again.
Durch diese Aufspaltung von Steuerteil und Leistungsteil ist nicht mehr ein Steuerteil mit einem Leistungsteil verbunden, sondern es wird die Möglichkeit gegeben durch ein Steuerteil bis zu 16 Leistungsteile ansprechen zu lassen, wodurch eine kosten*Unytige Herstellung ermöglicht wird.This division of the control section and power section is not more of a control part connected to a power part, but it becomes the possibility given by a control unit to address up to 16 power units, whereby a cost * Unytige production is made possible.
Durch die vorgeschlagene digitalisierte Kennlinie wird im Gegensatz zu der bisherigen analogen Kennlinienachbildung die Schaffung einer freiprogrammierbaren Kennlinie ermöglicht, welche kundenspezifische Erfordernisse berücksichtigt.In contrast, the proposed digitized characteristic the creation of a freely programmable one in addition to the previous analog characteristic curve simulation Characteristic enables which customer-specific requirements are taken into account.
Die vorgeschlagene konsequente Anwendung mikroelektronischer Bauelemente ermöglicht auch eine Funktionssicherung des Mikrocomputers durch eine galvanische Trennung von Leistungsteil und Phasenanschnittsteuerung durch ein Piëzokoppelelement. Der Mikrocomputer ist hierbei von der Peripherie über einen Optokoppler galdvanisch getrennt.The proposed consistent application of microelectronic components also enables a functional safeguarding of the microcomputer by means of a galvanic Separation of power section and phase control by a Piëzo coupling element. The microcomputer is galvanic from the periphery via an optocoupler separated.
Es läßt sich auch ein Entstörgrad N erzielen, in dem eine besondere Filterkombination (LC-Kombination) eingesetzt wird.A degree of interference suppression N can also be achieved in which a special Filter combination (LC combination) is used.
Im Gegensatz zu den bisher üblichen ungenormten Einschubgrößen und ungenormten Einschubbreiten wird ein normgerechter Aufbau der Einrichtung auf einer Europaplatine in 19"-Einschubtechnik vorgeschlagen.In contrast to the previously unstandardized slide-in sizes and Non-standard shelf widths will result in a standard-compliant structure of the device on a European circuit board proposed in 19 "slide-in technology.
Während bisher eine Übertemperatur in der Einrichtung lediglich gemeldet wurde, ist bei der erfindungsgemäßen Einrichtung eine Anzeige der Temperaturentwicklung im Leistungsteil und eine selbsttätige Abschaltung bei Übertemperatur vorgesehen.While so far an excess temperature in the facility has only been reported is, in the device according to the invention, an indication of the temperature development in the power section and an automatic shutdown in the event of excess temperature.
Das Betriebsprogramm ist zweckmäßig spannungsausfallsicher in EPROM 2716 abgespeichert.The operating program is expediently non-volatile in EPROM 2716 saved.
