Description
Die Erfindung betrifft einen elektronischen Maximumzähler, der einen Kilowattstundenzähler, eine Impulsabtasteinrichtung und ein elektronisches Maximumwerk mit einem Mikrocomputer und nichtflüchtigem Speicher aufweist.The invention relates to an electronic maximum counter, the one kilowatt hour meter, a pulse sampling device and an electronic maximum mechanism with a microcomputer and non-volatile memory.
Derartige elektronische Maximumwerke, wie sie z. B. in den DE-OS 26 13 112 und 26 22 845 dargestellt sind, besitzen aufgrund des vorhandenen Speichers die Möglichkeit, sämtliche auftretenden zwölf Monatsmaxima zu speichern und sie in geeigneter Weise auszugeben. Beim Einsatz von Maximumzählern als Haushaltszähler besteht bei den allgemein jährlichen Ablesezyklen die Gefahr der Falschnotierung von Zahlenwerten durch die schriftliche Übertragung von s zwölf mehrstelligen Zahlen. Eine Kumulierung der zwölf gemessenen Maxima würde zwar das Ableseverfahren vereinfachen, jedoch ist dadurch das Verschleifen der Spitzenbelastungen derart groß, daß der Einsatz von Maximumzahlern unwirtschaftlich istSuch electronic maximum works, as z. B. are shown in DE-OS 26 13 112 and 26 22 845, have the option of storing all twelve monthly maxima due to the memory available to save and output them in an appropriate manner. When using maximum counters as Household meters, with the general annual reading cycles, there is a risk of incorrectly quoting Numerical values through the written transfer of s twelve multi-digit numbers. An accumulation of the Twelve measured maxima would simplify the reading process, but this would result in smoothing the peak loads are so great that the use of maximum payers is uneconomical
Der Erfindung liegt die Aufgabe zugrunde, unter Beibehaltung der Vorteile der Maximumzählung eine
Verringerung der Anzahl der abzulesenden Monatsmaxima zu ermöglichen.
Diese Aufgabe ist durch die Erfindung gelöst, die in den kennzeichnenden Teilen der Patentansprüche zum
Ausdruck kommtThe invention is based on the object of making it possible to reduce the number of monthly maxima to be read while maintaining the advantages of maximum counting.
This object is achieved by the invention, which is expressed in the characterizing parts of the patent claims
Der im Maximumwerk vorhandene Rechner wird durch ein z.B. in seinem Festwertspeicher gesetztes Programm derart gesteuert, daß er die zwölf Monatsmaxima eines Jahres einzeln speichert und diese auf einen Befehl hin entweder einzeln ausgibt oder selbsttätig die Zahl deren höchsten Maxima, beispielsweise vier, Findet, speichert und nach einem Abfragebefehl ausgibt Weiterhin ist entsprechend dem gespeicherten Programm und einem gesonderten Abfragebefehl die Errechnung eines Mittelwertes der η höchsten Maxima vorgesehen. Mit der Mittelwertbildung aus den π höchsten Maxima ist eine einzige Zahlenwertangabe für die jährliche Zählerablesung unter Beibehaltung derThe computer present in the maximum work is controlled by a program set in its read-only memory, for example, in such a way that it individually saves the twelve monthly maxima of a year and either outputs them individually or automatically finds the number of their highest maxima, for example four, finds and saves them outputs after an interrogation command Furthermore, the calculation of an average value of the η highest maxima is provided in accordance with the stored program and a separate interrogation command. With the averaging of the π highest maxima, a single numerical value is given for the annual meter reading while maintaining the
Das Rechenwerk des Mikrocomputers ist zur Errechnung und Ausgabe von π höchsten Maxima derart gesteuert, daß es vor dem Speichern eines jeden neuen Monatsmaximums ausrechnet ob dieses höher oder niedriger a!s der kleinste bereits gespeicherte Wert ist. Ist das neue Monatsmaximum niedriger als einer der η gespeicherten höchsten Maximumwerte, so wird es nicht gespeichert, ist es höher, wird der kleinste der η gespeicherten Werte gelöscht und der neue Wert in den nichtflüchtigen Speicher gesetzt.The arithmetic unit of the microcomputer is controlled for calculating and outputting π highest maxima in such a way that before each new monthly maximum is stored it calculates whether this is higher or lower than the lowest value already stored. If the new monthly maximum is lower than one of the η stored highest maximum values, it is not stored, if it is higher, the lowest of the η stored values is deleted and the new value is placed in the non-volatile memory.
Bei der Ausgabe von zwölf Maximawerten sind diesen außer den Monatskennungen eine Kennung zur Verdeutlichtung der Anzeige von Maximumwerten zugeordnetWhen outputting twelve maximum values, these are, in addition to the month IDs, an ID for Clarification of the display of maximum values assigned
