Description

Die Erfindung betrifft ein mobiles Kühlschmierstoffüberwachungssystem gemäß Anspruch 1.The invention relates to a mobile cooling lubricant monitoring system according to claim 1.

Es gibt Systeme am Markt (Bsp: Kühlschmierstoff-Manager und Sensor • LIQUIDTOOL, Fa. Liquidtool Systems AG), welche durch Messung der Konzentration und Temperatur des Kühlschmierstoffs eine Überwachung des Kühlschmierstoffes bei Werkzeugmaschinen realisieren. Die Systeme sind nicht modular aufgebaut und benötigen meistens eine WLAN-Verbindung vor Ort.There are systems on the market (e.g. cooling lubricant manager and sensor • LIQUIDTOOL, from Liquidtool Systems AG) which monitor the cooling lubricant in machine tools by measuring the concentration and temperature of the cooling lubricant. The systems are not modular and usually require a WiFi connection on site.

Aufgabe der Erfindung ist es diese Nachteile zu überwinden.The object of the invention is to overcome these disadvantages.

Gelöst wird diese Aufgabe durch ein mobiles Kühlschmierstoffüberwachungssystem gemäß Anspruch 1.This task is solved by a mobile cooling lubricant monitoring system according to claim 1.

Nachfolgend ist die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail below with reference to an exemplary embodiment illustrated in the drawing.

  • 1 Schwimmkörper mit zwei Sensoren
  • 2 erfindungsgemäßes Messsystem
  • 3 Blockdiagramm Gateway

2. zeigt das erfindungsgemäße mobile Messsystem zur Kühlmittelschmierstoffüberwachung. 2 . shows the mobile measuring system according to the invention for coolant lubricant monitoring.

3 zeigt ein Blockdiagramm des Gateways
Das Messsystem MS besteht aus einem pH-Sensor pH und einem Leitfähigkeitssensor Lf (LDL100, Fa ifm electronic gmbh), die ihre Messwerte an ein Gateway (IO-Key Fa. ifm electronic gmbh) per IO-Link übertragen. 3 shows a block diagram of the gateway
The MS measuring system consists of a pH sensor pH and a conductivity sensor Lf (LDL100, from ifm electronic gmbh), which transmit their measured values to a gateway (IO key from ifm electronic gmbh) via IO-Link.

Vom Gateway werden die Messwerte an ein Endgerät z. B. ein Smartphone, Laptop, Tablet etc. über ein Kommunikations-Netzwerk z. B. GSM-Netz weitergeleitet.The measured values are transmitted from the gateway to a terminal device, e.g. B. a smartphone, laptop, tablet etc. via a communication network z. B. GSM network forwarded.

Im Gateway G können auch Schwellwerte hinterlegt sein, um gegebenenfalls einen Aktor anzusteuern.Threshold values can also be stored in the gateway G in order to control an actuator if necessary.

Nachfolgend ist die Funktion der Erfindung näher erläutert.The function of the invention is explained in more detail below.

Schwimmkörper, AIK001, LDL100, DP2200, EVC Kabel und ein ph-Wert Sensor pH ergeben ein mobiles System zur Kühlschmiermittelüberwachung. Mittels SIM Karte werden Über- oder Unterschreitung von voreingestellten Grenzwerten an den Betreiber per Email oder SMS übermittelt.Float, AIK001, LDL100, DP2200, EVC cable and a pH value sensor result in a mobile system for cooling lubricant monitoring. Using a SIM card, exceeding or falling below preset limit values are sent to the operator by email or SMS.

Der LDL100 mißt Temperatur und Leitfähigkeit. Nachgewiesen in Experimenten wurde, daß mit steigendem Ölgehalt (2%, 4%, 6%) die Leitfähigkeit zunimmt. Heißt im Umkehrschluß: Wenn der Anwender nur Wasser auffüllt, verändert sich das Öl-Wasserverhältnis. Somit kann eine Veränderung einwandfrei dargestellt und kommuniziert werden.The LDL100 measures temperature and conductivity. Experiments have shown that conductivity increases with increasing oil content (2%, 4%, 6%). Conversely, if the user only fills up with water, the oil-water ratio changes. In this way, a change can be displayed and communicated perfectly.

Der ph-Wert Sensor zeigt an, sobald sich der KSS in Richtung „Umkippen“ verändert. Bakterienbefall des KSS hat ebenfalls Auswirkung auf den ph-Wert. Somit kann der Anwender auch dieser Indikation auf Basis der veränderten Meßwerte nachgehen. Der Schwimmkörper SK könnte mittels Magnethalterung am inneren Beckenrand befestigt werden.The pH value sensor indicates as soon as the KSS changes in the direction of "overturning". Bacterial infestation of the KSS also has an effect on the pH value. The user can therefore also follow this indication on the basis of the changed measured values. The SK floating body could be attached to the inner edge of the pool using a magnetic holder.

Im IO-Key können die Gut- und Warnwerte durch den Anwender einfach eingestellt (oder auf Wunsch voreingestellt) werden. Somit würde der Kunde ein vorkonfiguriertes System beziehen können.In the IO key, the good and warning values can be easily set (or preset if desired) by the user. In this way, the customer would be able to purchase a pre-configured system.
