Abstract
Description
Stand der TechnikState of the art
Die Erfindung betrifft eine Vorrichtung, die die Einspeisung von Energie an mehreren Stellen des AS-Interface Netzes erlaubt.The invention relates to a device which is the feeding of energy at several points of the AS-Interface Network allowed.
Ein AS-Interface Netz1 nach EN50295 besteht aus einem AS-Interface Master (im folgenden "Master" genannt), einem AS-Interface Netzteil und einem oder mehreren AS-Interface Slaves (im folgenden "Slaves" genannt), die über eine Zweidrahtleitung miteinander verbunden sind.An AS-Interface network 1 according to EN50295 consists of an AS-Interface master (hereinafter referred to as "master"), an AS-Interface power supply and one or more AS-Interface slaves (hereinafter referred to as "slaves"), which are connected via a two-wire cable are interconnected.
Eine Besonderheit von AS-Interface ist, dass Energie und Daten auf demselben Zwei-Leiterkabel übertragen werden. Die Energie wird als Gleichspannung von ca. 30V bereitgestellt, während die Daten vom Master und den Slaves als Stromimpulse aufmoduliert werden. Durch eine charakteristische Induktivität im AS-Interface Netzteil erzeugen die Stromimpulse Spannungsimpulse auf der Leitung, die der Gleichspannung zur Energieversorgung überlagert sind. Die Empfänger in Master und Slaves reagieren auf diese Spannungsimpulse.A specialty of AS-Interface is that energy and data are transmitted on the same two-wire cable become. The energy is provided as a DC voltage of approx. 30V, while the data from the master and the slaves are modulated as current pulses become. With a characteristic inductance in the AS-Interface power supply the current pulses generate voltage pulses on the line that the DC voltage for power supply are superimposed. The recipients in Masters and slaves react to these voltage pulses.
Um die Spannungsimpulse entstehen zu lassen und nicht zu dämpfen oder zu verzerren, sind strenge Regeln1 hinsichtlich der Impedanz von Master, Slave und AS-Interface Netzteil einzuhalten. Insbesondere müssen Master und Slaves sowie alle anderen, an das AS-Interface Netz angeschlossenen Elemente (Repeater etc.) im Frequenzbereich der Spannungsimpulse (ca. 50..300kHz) hinreichend hochohmig sein. Dies erfordert eine Impedanz-Charakteristik mit einer Mindestinduktivität. Master und Slaves sind Energieverbraucher, während das AS-i Interface Netzteil, das nur einmal in einem AS-Interface Segment vorkommen darf, Energie liefert. Durch den Leitungswiderstand und den Verbrauch von Master und Slaves kommt es zu einem Spannungsverlust auf der AS-Interface Leitung, so dass unter Umständen (hoher Verbrauch der Slaves, lange Leitungen) die Spannung für einzelne Slaves zu gering wird.In order to generate the voltage pulses and not to dampen or distort them, strict rules 1 regarding the impedance of the master, slave and AS-Interface power supply must be observed. In particular, masters and slaves as well as all other elements (repeaters etc.) connected to the AS-Interface network must be sufficiently high-resistance in the frequency range of the voltage pulses (approx. 50..300kHz). This requires an impedance characteristic with a minimum inductance. Masters and slaves are energy consumers, while the AS-i interface power supply, which may only appear once in an AS-interface segment, supplies energy. Due to the line resistance and the consumption of master and slaves, there is a voltage loss on the AS-Interface line, so that under certain circumstances (high consumption of the slaves, long lines) the voltage for individual slaves becomes too low.
Der Ausweg ist nach dem Stand der Technik, entweder Leitungen mit größerem Querschnitt zu verwenden oder das AS-Interface Netz mit Hilfe von Repeatern in mehrere Segmente aufzuteilen, die dann einzeln von je einem AS-Interface Netzteil versorgt werden. Allerdings hat das genormte AS-Interface Profilkabel, das vorteilhafterweise in AS-Interface Netzen verwendet wird, einen festgelegten Querschnitt von 1,5mm2, so dass das Ausweichen auf größere Kabel den Verzicht auf das Standardkabel bedeutet. Auch die Benutzung von Repeatern ist limitiert, da zwischen Master und jedem einzelnen Slave maximal 2 Repeater erlaubt sind.According to the state of the art, the way out is either to use cables with a larger cross-section or to split the AS-Interface network into several segments with the help of repeaters, which are then supplied individually by one AS-Interface power supply unit. However, the standardized AS-Interface profile cable, which is advantageously used in AS-Interface networks, has a fixed cross-section of 1.5mm 2 , so that switching to larger cables means that the standard cable is not used. The use of repeaters is also limited, since a maximum of 2 repeaters are allowed between the master and each individual slave.
Erfindunginvention
Der Erfindung liegt die Aufgabe zugrunde, an mehreren Stellen und nicht nur am zentralen AS-Interface Netzteil Energie einzuspeisen, um auch bei langen Leitungen und/oder großem Stromverbrauch eine ausreichende Spannung auf der AS-Interface Leitung zur Verfügung zu stellen.The invention is based on the object in several places and not only on the central AS-Interface power supply Feed in energy to ensure that even with long cables and / or high power consumption sufficient voltage is available on the AS-Interface cable put.
Die Aufgabe wird dadurch gelöst, dass zusätzliche Gleichstrom-Netzgeräte angeschlossen werden, deren Impedanzen im Frequenzbereich der Spannungsimpulse (ca. 50..300kHz) so hoch ist, dass sie die Datenübertragung nicht beeinflussen.The task is solved in that additional DC power supplies are connected, their impedances in the frequency range of the voltage pulses (approx. 50..300kHz) is so high that it does not affect the data transmission.
Diese zusätzlichen Netzgeräte speisen somit zusätzlich Energie in das AS-Interface Netz ein, ohne die beschriebenen Nachteile aufzuweisen.Feed these additional power supplies thus additional Energy into the AS-Interface network without the disadvantages described exhibit.
Vorteilhafterweise kann die zusätzliche Energie an einem oder mehreren Orten großen Stromverbrauchs eingespeist werden.Advantageously, the additional Energy fed into one or more places of high electricity consumption become.
Die
Wirtschaftlicher Wert der Erfindungeconomic Value of the invention
Der wirtschaftliche Wert der Erfindung liegt darin, dass es damit möglich ist, eine ausreichende Stromversorgung für AS-Interface Netze sicherzustellen, ohne auf größere Kabelquerschnitte oder auf Repeater zurückgreifen zu müssen. Ein erfindungsgemäßes Netzgerät ist preiswerter als ein Repeater mit einem weiteren AS-Interface Netzteil.The economic value of the invention is that it makes it possible is to ensure an adequate power supply for AS-Interface networks, without having to use larger cable cross sections or use repeaters to have to. A power supply according to the invention is cheaper as a repeater with another AS-Interface power supply.
