Einrichtungen zur Leistungs- und/oder Qualitätskontrolle von elektrischen Netzen sind als PMD (Power Monitoring Device) und PQM (Power Quality Monitoring) bekannt. Diese Einrichtungen sind heute meist als intelligente Messgeräte mit Strom- und Spannungseingängen ausgeführt. Die durch die elektrischen Leitungen des elektrischen Netzes fließenden Ströme und deren Spannungen werden als elektrische Signale von einer dafür vorgesehenen Einrichtung bewertet, die meist softwaremäßig mittels eines Mikrocontrollers realisiert ist. Die Stromversorgung der Einrichtung erfolgt dabei meist extern.Facilities for power and / or quality control of electrical networks are known as PMD (Power Monitoring Device) and PQM (Power Quality Monitoring). These devices are today usually designed as smart meters with current and voltage inputs. The currents flowing through the electrical lines of the electrical network and their voltages are evaluated as electrical signals from a device provided for this purpose, which is usually realized by software by means of a microcontroller. The power supply of the device is usually external.
Nachteilig bei den bekannten Einrichtungen ist, dass bei Ausfall der Stromversorgung nicht nur die aktuellen Daten, sondern auch die diesen vorausgehenden Daten verloren gehen können.A disadvantage of the known devices is that if the power supply fails not only the current data, but also the previous data can be lost.
Die Aufgabe der Erfindung ist es, die Datenerfassung und -speicherung bei Einrichtungen zur Leistungs- und/oder Qualitätskontrolle sicherzustellen.The object of the invention is to ensure the data acquisition and storage in facilities for performance and / or quality control.

Die Erfindung sieht vor, dass eine in die Einrichtung integrierte unterbrechungsfreie Spannungsversorgung (USV) vorgesehen ist, umfassend: einen elektrischen Energiespeicher eine Ladeeinrichtung, welche den Zustand des Energiespeichers überwacht und seine Aufladung steuert, eine Überwachung der externen Stromversorgung und eine Umschalteinrichtung, welche die externe Stromversorgung überwacht und bei Störungen auf Energiespeicher-Betrieb umschaltet. Die Erfindung besteht also darin, eine unterbrechungsfreie Spannungsversorgung mit einem elektrischen Energiespeicher in die Einrichtung zu integrieren, wobei der Energiespeicher von der Einrichtung überwacht und geladen wird. Gleichzeitig wird die externe Stromversorgung überwacht und bei Störungen wird auf Energiespeicher-Betrieb umgeschaltet. Die Umschalteinrichtung sorgt also dafür, dass bei Bedarf jeweils selbsttätig von der externen Stromversorgung, d. h. Normalbetrieb, auf Notbetrieb mit Energiespeicher umgeschaltet wird. Dazu erforderlich ist die Überwachung der Stromversorgung. Das Erkennen eines Ausfalls der Stromversorgung kann parameterabhängig erfolgen, wobei die Spannungshöhe und die Zeit vorzugsweise als Parameter dienen.The invention provides that an integrated into the device uninterruptible power supply (UPS) is provided, comprising: an electrical energy storage, a charging device which monitors the state of the energy storage and controls its charging, monitoring the external power supply and a switching device which the external Monitored power supply and switches to energy storage operation in case of faults. The invention thus consists in integrating an uninterruptible power supply with an electrical energy store in the device, wherein the energy storage is monitored and loaded by the device. At the same time, the external power supply is monitored and in the event of a fault, it switches to energy storage mode. The switching device thus ensures that, if necessary, each time automatically from the external power supply, d. H. Normal operation, switched to emergency operation with energy storage. This requires the monitoring of the power supply. The detection of a failure of the power supply can be done parameter-dependent, the voltage level and the time are preferably used as a parameter.
Zweckmäßigerweise erfolgt die Überwachung und Aufladung des Energiespeichers, die Überwachung der externen Stromversorgung und das Umschalten auf Energiespeicher-Betrieb softwaremäßig mit Hilfe des Mikrocontrollers.Appropriately, the monitoring and charging of the energy storage, the monitoring of the external power supply and switching to energy storage operation is done software by means of the microcontroller.
Bei einer einfachen Ausführung ist der elektrische Energiespeicher ein externer Akkumulator.In a simple embodiment, the electrical energy store is an external accumulator.
Zweckmäßigerweise wird auch die Bewertungseinrichtung softwaremäßig durch den Mikrocontroller gebildet.Expediently, the evaluation device is also formed by the software by the microcontroller.
Die Einrichtung lässt sich weiter vereinfachen, wenn die externe Stromversorgung eine Zwischenspannung bereitstellt, aus der dann wieder unterschiedliche Versorgungsspannungen gebildet werden.The device can be further simplified if the external power supply provides an intermediate voltage from which then different supply voltages are formed again.
Mit Vorteil ist auch eine Datenverarbeitung zur Aufbereitung und Verarbeitung der Signale vorgesehen. Diese weist eine Datenausgabe auf, die eine externe Kommunikation umfasst.Advantageously, a data processing for processing and processing of the signals is provided. This has a data output, which includes an external communication.

Die Stromversorgungseinheit SE versorgt einen Mikrocontroller (nicht gezeigt) mit elektrischem Strom. Außerdem liefert sie den (Lade-)Strom für einen externen Energiespeicher EXThe device is connected to two independent external power supplies S1, S2, which are connected to an internal power supply unit SE. The power supply unit SE supplies a microcontroller (not shown) with electric power. It also supplies the (charging) current for an external energy store EX

Dabei werden die Messdaten mittels der Messdatenverarbeitung und -speicherung MVS bewertet, die hier als softwaremäßig ausgeführte Bewertungseinrichtung fungiert. Die Messdaten als auch deren Bewertungen werden in einem Speicher der Einrichtung abgelegt.In this case, the measurement data are evaluated by means of the measurement data processing and storage MVS, which here functions as a software evaluation facility. The measurement data as well as their ratings are stored in a memory of the device.
Zur Anzeige der Daten und Bewertungen dient die Datenausgabe DAK, wobei die Daten auch über eine zugehörige externe Datenkommunikation ausgegeben werden können.The data output DAK serves to display the data and evaluations, whereby the data can also be output via an associated external data communication.
Aus der Stromversorgung S1 wird mittels eines Netzteils NT eine Zwischenspannung S1Z gebildet. Diese dient zum Aufladen des externen Energiespeichers EX. Dazu ist eine Ladeeinrichtung LE der zentralen Einheit ZE vorgesehen, die ebenfalls softwaremäßig durch den Mikrocontroller gesteuert wird. Die Ladeeinrichtung LE überwacht den externen Energiespeicher EX und sorgt für dessen Aufladung. Weiter ist eine vom Mikrocontroller gesteuerte und zur zentralen Einheit ZE gehörende Umschalteinrichtung UE vorhanden, welche die externen Stromversorgungen S1, S2 überwacht und bei Störungen jeweils auf Energiespeicher-Betrieb umschaltet.From the power supply S1, an intermediate voltage S1Z is formed by means of a power supply NT. This serves to charge the external energy store EX. For this purpose, a charging device LE of the central unit ZE is provided, which is also controlled by the software by the microcontroller. The charging device LE monitors the external energy store EX and ensures its charging. Next is a controlled by the microcontroller and belonging to the central unit ZE switching device UE available, which monitors the external power supplies S1, S2 and switches in case of disturbances in each case to energy storage operation.
Von der zentralen Einheit ZE (und damit vom Mikrocontroller MC) gesteuert, wird aus der Zwischenspannung S1Z eine Zwischenspannung S2Z erzeugt, welche wiederum zur Erzeugung mehrerer Spannungen SU1, SU2, SU3 (Spannungsversorgungen) dient. Dies erfolgt mittels eines Netzteils NTU, bei dem es sich selbstverständlich auch um mehrere Netzteile handeln kann.Controlled by the central unit ZE (and thus by the microcontroller MC), an intermediate voltage S2Z is generated from the intermediate voltage S1Z, which in turn serves to generate a plurality of voltages SU1, SU2, SU3 (power supplies). This is done by means of a power supply NTU, which of course may also be multiple power supplies.
