Title:
Messdatenerfassungsgerät mit Anschlussbuchsen Gattung das Anrneidungsgegenstsnäss;
Ois Erfindung bezieht sich auf computergesteuert» Messdatensrfss-Data acquisition device with connection sockets type the object of application;
The invention relates to computer-controlled measurement data
bs-iieht-nd aus einzelnen Baugruppenbs-iieht-nd from individual modules
seit einer Vielzahl von Jahren bekannt. Die Baugruppen sind Multiplexer, Ueretärker, Netzteile, Temperaturnormale, AD-Uandler u.a. Ein kompaktes univaraallea, Gerät meines* einzelne Baugruppen Variationen überflüssig macht, gibt as bislang noch nicht. Die meist analogen rtessignale uierden mit dem Messdatenerfassungssuatem in digitale Warte gewandelt und dann an einen Computer zur (Verarbeitung weitergeleitet.known for many years. The components are multiplexers, amplifiers, power supplies, temperature standards, AD converters, etc. There is not yet a compact universal device that makes individual component variations superfluous. The mostly analogue test signals are converted into digital signals using the measurement data acquisition system and then forwarded to a computer for processing.
Es 1st bekannt, Meßgrößenerfaaaung mit wenig kompakten und speziell ausgerichteten Systemen für meist wenige physikalische Meßgrößen. Nachteile dieser Lösungen sind din fehlende Anpassung an verschiedene Computer, weiterhin der gegenüber dem neuen Gerat umständliche und nicht kompakte Aufbau, dar weniger variable Einsatz für verschiedene Meßfühler. Eai keinem bis heute bekanntem System ist es möglich, aua einer vorbereiteten, kalibrierten Auswahl von Meßfühlern durch eine einfache Steckverbindung einen gewünschten, beliebigen Sensor anzupassen. Vielmehr sind bis heute Temperaturnormale, Brückendiaganal- und Uersorgungsspannungan getrennt zu liefern, nichtllrware, billige Sensoren können nur bedingt verwendet werden, für evtl. Verstärkung von Meßsignalen und Störsignalunterdrückung lat ein getrennter Verstärker erforder-It is known to record measured quantities using less compact and specially designed systems for mostly a few physical measured quantities. Disadvantages of these solutions are the lack of adaptation to different computers, the cumbersome and less compact design compared to the new device, the less variable use of different measuring sensors. No system known to date makes it possible to adapt any desired sensor to a prepared, calibrated selection of measuring sensors using a simple plug connection. Instead, temperature standards, bridge diagonal and supply voltage have to be supplied separately, which is not cheap, cheap sensors can only be used to a limited extent, a separate amplifier is required for possible amplification of measuring signals and interference signal suppression.
lich, für andere Anpassungen sind Spannungsteiler zu verwenden. Daraus resultiert der oft tagelange Aufbau für einen speziellen Versuch und die damit verbundenen hohen Kosten.voltage dividers must be used for other adjustments. This often results in days of setup time for a specific test and the associated high costs.
Aufgabe:Task:
Der Erfindung liagt üia Aufg&&& ityjartmde, eine Anordnung zu entwickeln, welche Nachtsiis bekannter Anordnungen überwindet. Insi^ündere war bisher sin Nachteil, dar fehlende universelle Einsatz und der nicht kompakte Aufbau. Hier wurde eine einfachere, aber zugleich wirkungsvollere Lösung eines Meßdatene^fassungsgerätes gefunden.The invention has the objective of developing an arrangement which overcomes the disadvantages of known arrangements. The disadvantage up to now was the lack of universal application and the non-compact construction. Here a simpler but at the same time more effective solution for a measurement data acquisition device has been found.
Lösung:Solution:
dadurch gekennzeichnet, das die riessdatenerfci^sungsschaltung in einem kompakten Gehäuse untergebracht ist und über ein Verbindungskabel mit einem Computer verbindbar ist. Die an der Vorderfront des PießdatsnerfassungsgerSt liegenden Anschlußbuchsen können nicht nur die Messignale über Kontakte aufnehmen, sondern stellen auch Betriebsspannungen für die Sensoren oder Sensoranpassungsschaltungen über Kontakte zur Verfügung. Jede Anschlußbuchse muß mit mindestens drei Kontakten versehen sein. Diese sind erstens die Masseleitung, zweitens die riessignalleitung und drittens die Versorgungsspannungslsitung. Im Bshtiuse: Vor- den Buchsen führen intern im Gehäuse leitende Verbindungen zu mindestens einem rechnergesteuerten Zeitmultiplexer. Weitere leitende Verbindungen führen von den ZeitmultiplexerCn) zu einem rechnergesteuertem Verstärker mit nachfolgendem Analog Digital Wandler. Vom Analog Digital Wandler führen leitende Verbindungen zu Treiber- und Pufferbausteinen. Lie Treiber- und Pufferbausteine sind mit dem Verbindungskabel leitend verbunden.characterized in that the data acquisition circuit is housed in a compact housing and can be connected to a computer via a connecting cable. The connection sockets on the front of the data acquisition device can not only receive the measurement signals via contacts, but also provide operating voltages for the sensors or sensor adaptation circuits via contacts. Each connection socket must be provided with at least three contacts. These are firstly the ground line, secondly the data signal line and thirdly the supply voltage line. In the example: In front of the sockets, conductive connections lead internally in the housing to at least one computer-controlled time multiplexer. Further conductive connections lead from the time multiplexers to a computer-controlled amplifier with a subsequent analog-digital converter. Conductive connections lead from the analog-digital converter to driver and buffer components. The driver and buffer components are conductively connected to the connecting cable.
Jede Anschlußbuchse ist mit fünf Kontakten belegt. Dletta sind die gemeinsame Masseleitung, zwei Leitungen für den DifferenzeingangEach connector socket has five contacts. Three are the common ground line, two lines for the differential input
dea Yerethrkere und zwei Leitungen für die Brückendiagonalvereorgungaapannung. Jede Buchse kann mit einem beliebigen Sensor belegt werden. Einige heute erhältliche Sensoren, bzw. deren Meßgrößen sind: Temperatur, Druck, Kraft, Strom, Spannung, pH-Wert, Feldstärken, winkel, Lunge, Zeit, Durchfluß, tiaeeenetrom, Biopotentiale, Frequenz, Beleuchtungsstärke, Strahlung, Feuchtigkeit, Ionenselektive Konzentration. Figur S-B zeigt die Beschaltung verschiedener Sensoren für daß fießdatenerfaasungsgerttt. Diese Anwendungsbeispiele mit steckbaren Sensoren zeigen deutlich, daß Mi«· ßo*n*inr"mn ninhf nrnitti m««in Di ir^Hsan »&igr; irv«*i-ir*Hnat* annHarn HmI IaHin ___ __..__._.. ..__.._ „_____.... ___..__.. __.„__. _..__, „ .. m the Yerethrkere and two lines for the bridge diagonal supply voltage. Each socket can be connected to any sensor. Some sensors available today, or their measured variables, are: temperature, pressure, force, current, voltage, pH value, field strengths, angle, lung, time, flow, tiaeenetr, biopotentials, frequency, illuminance, radiation, humidity, ion-selective concentration. Figure 5B shows the wiring of various sensors for the flow data acquisition device. These application examples with pluggable sensors clearly show that Mi«· ßo*n*inr"mn ninhf nrnitt i m««in Di ir^Hsan »&igr; irv«*i-ir*Hnat* annHarn HmI IaH in ___ __..__._.. ..__.._ „_____.... ___..__.. __.„__. _..__, „ .. m
vertauscht werden können. Dadurch wird der universelle Einsatz zusätzlich erhöht. Sofort nach Zustandekommen der Steckverbindung können die Messungen durchgeführt werden. Das Meßsignal wird von den Buchsen intern zu mindestens einem rechnergesteuerten Zeitmultiplexer weitergeleitet. Uom Zeitmultiplexer wird es über einen computergesteuerten UeratMrker, einem Analog Digital wandler zugeführt und danach über eine Anpeseungsscheltung an den Computer weitergegeben. Mit der Anpessungsscheltung ist ein Anschluß an beliebige Computer möglich. Durch die Geeamtanordnung wird weiterhin überraschenderweise erreicht, daß eine Umschaltung auf mindestens zwei Uerstärkungsbereiche möglich ist, so daß extreme Anforderungen im Meßbereich auf einfache weise gelöstcan be swapped. This further increases the universal use. Measurements can be carried out immediately after the plug connection has been made. The measurement signal is forwarded internally from the sockets to at least one computer-controlled time multiplexer. From the time multiplexer it is fed via a computer-controlled converter, an analog digital converter and then passed on to the computer via a power circuit. The power circuit enables connection to any computer. The overall arrangement also surprisingly enables switching to at least two amplification ranges, so that extreme requirements in the measurement range can be met in a simple manner.
