Abstract
Description
Die Erfindung betrifft eine Messvorrichtung zur frühzeitigen Erfassung eines Schadens an einem Maschinenteil, bestehend aus Messsensor und einem Messinstrument, das eine Leiterplatte mit integrierten Schaltungen, zumindest Schnittstellen für den Messsensor sowie eine Batterie aufweist.The invention relates to a measuring device for early Detection of damage to a machine part, consisting of a measuring sensor and a measuring instrument that integrated a printed circuit board Circuits, at least interfaces for the measuring sensor and one Battery.
Eine Messvorrichtung mit den eingangs beschriebenen Merkmalen ist aus WO 01/25678 A1 bekannt. Die bekannte Messvorrichtung erlaubt eine zustandsorientierte Instandhaltung eines Wälzlagers ohne Anschluss an ein zentrales Wälzlagerüberwachungssystem. Zu diesem Zweck erkennt die Messvorrichtung einen beginnenden Lagereffekt oder einen Mangelschmierungszustand. Bei der bekannten Vorrichtung ist die Messvorrichtung an einen Schmierstoffspender angeschlossen, der durch geeignete, von der elektronischen Steuerung vorgegebene Zusatzschmierungen den Schadensverlauf verzögert. Ein erforderlicher Lagerwechsel kann daher im Rahmen langfristig geplanter Instandhaltungsarbeiten durchgeführt werden.A measuring device with the input described features is known from WO 01/25678 A1. The well-known Measuring device allows condition-based maintenance of a rolling bearing without Connection to a central rolling bearing monitoring system. For this purpose, the measuring device detects a beginning bearing effect or a lack of lubrication. In the known device the measuring device is connected to a lubricant dispenser, the one specified by the electronic control Additional lubrication delays the damage process. A necessary change of bearings can therefore be part of long-term planned maintenance work carried out become.
Der Erfindung liegt die Aufgabe zugrunde, eine Messvorrichtung der eingangs beschriebenen Art anzugeben, die autark und stromsparend arbeitet. Darüber hinaus soll die Messvorrichtung in explosionsgeschützten Bereichen einsetzbar sein.The invention has for its object a Measuring device of the type described above to indicate the self-sufficient and works in an energy-saving way. About that In addition, the measuring device should be in explosion-proof areas be applicable.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass der Messsensor eine von dem Messinstrument mit Strom versorgte Einrichtung für die Aufnahme analoger Messsignale aufweist, dass die integrierten Schaltungen die Stromversorgung des Messsensors in vorgegebenen Intervallen lediglich kurzzeitig freigeben und die Stromversorgung nach Erfassung aktueller Messwerte wieder unterbrechen und dass die Batterie zur Vermeidung von Spannungsabfällen auf der Leiterplatine aufgelötet ist. Die Batterie erlaubt eine autarke Stromversorgung von Messsensor und Messinstrument. Durch die lediglich kurzzeitige Freigabe der Stromversorgung des Messsensors wird eine deutliche Reduzierung des Stromverbrauchs erzielt.According to the invention the object is achieved in that the measuring sensor is a device powered by the measuring instrument for the Recording analog measurement signals that the integrated circuits the power supply of the measuring sensor at predetermined intervals only release briefly and the power supply after detection interrupt the current measured values again and that the battery for Avoidance of voltage drops soldered onto the circuit board is. The battery allows an independent power supply from the measuring sensor and measuring instrument. By only briefly releasing the Power supply to the measuring sensor will be a significant reduction of electricity consumption achieved.
Die Auflötung der Batterie auf die Leiterplatine vermeidet Spannungsabfälle und verhindert die Entstehung von Funken an den Kontaktstellen zwischen Leiterplatine und Batterie, so dass die Messvorrichtung auch in explosionsgeschützten Bereichen einsetzbar ist. Erfindungsgemäß können ohne Batterieaustausch lange Standzeiten von bis zu einigen Jahren erreicht werden.Soldering the battery onto the circuit board avoids voltage drops and prevents the generation of sparks at the contact points between PCB and battery, so that the measuring device also in explosion-proof Areas can be used. According to the invention, without battery replacement long service lives of up to a few years can be achieved.
Die Batterie kann aus einer Lithiumbatterie mit druckdicht verschweißtem Batteriegehäuse bestehen. Lithiumbatterien zeichnen sich durch sehr lange Betriebszeiten aus. Das druckdicht verschweißte Batteriegehäuse verhindert das Eindringen von Luftfeuchtigkeit, die die Funktion der Batterie beeinträchtigen kann.The battery can be made from a lithium battery welded pressure-tight battery case consist. Lithium batteries are characterized by very long operating times out. The welded pressure-tight battery case prevents the ingress of humidity, which the function the battery can.
Ein beginnender Schaden des Maschinenteils kann sich sowohl durch eine erhöhte Reibung zwischen feststehenden und bewegten Komponenten des Maschinenteils als auch durch eine erhöhte Vibration des Maschinenteils äußern. Gemäß einer bevorzugten Ausführung der Erfindung enthält der Messsensor daher einen Halbleiterbaustein für Temperaturmessungen und/oder einen zweiachsigen Sensor für die Aufnahme von Beschleunigungswerten.A beginning damage to the machine part can be increased by both Friction between fixed and moving components of the machine part as well as increased vibration of the machine part. According to a preferred execution of the invention the measuring sensor is therefore a semiconductor module for temperature measurements and / or a biaxial sensor for the recording of acceleration values.
Der Messsensor kann mit einem Analog/Digital-Wandler ausgerüstet sein. Dies führt zu einer weiteren Reduzierung des Stromverbrauchs, da die Übertragung digitaler Signale vom Messsensor zum Messinstrument nur einen äußerst geringen Energiebedarf verursacht.The measuring sensor can be used with an analog / digital converter equipped his. this leads to to further reduce electricity consumption since the transmission digital signals from the measuring sensor to the measuring instrument only an extremely low one Energy demand caused.
Gemäß einer weiteren bevorzugten Ausführung der Erfindung weist der Messsensor einen IC-Baustein zur Mittelwertbildung der Messsignale auf. Hierdurch wird der Einfluss von kurzzeitigen Extremwerten sowie von Fehlmessungen auf die Schmierstoffversorgung des Maschinenteils reduziert.According to another preferred execution According to the invention, the measuring sensor has an IC module for averaging of the measurement signals. This will reduce the influence of short-term Extreme values as well as incorrect measurements on the lubricant supply of the machine part reduced.
Im Rahmen der Erfindung liegt es, dass das Messinstrument Schnittstellen zum Anschluss an eine elektronische Steuerung eines dezentralen elektromechanischen Schmierstoffspenders aufweist, der das Maschinenteil mit Schmierstoff versorgt.It is within the scope of the invention that the measuring instrument interfaces for connection to an electronic Control of a decentralized electromechanical lubricant dispenser which supplies the machine part with lubricant.
