Description
Analoger linearer direktpreportionaler @echanisch-elektrischerAnalogue linear direct proportional @ echanical-electrical
Drehwinkelgeber für un@ndlich@ Drehwinkel Bekanntes Der Stand der Technik weist eine Vielzahl von mechanischelektrisch arbeitenden Drshwinkelgebersystemen aus, welche jedoch im allgemeinen den zu bestimmenden Drehwinkel als einon Phasen-Amplituden-Wert darstellen, der aus sinusförmigen Speisespannungon drehwinkelabhängig gewennen wird. Hierbe@ wird die Verknüpfung zwischen mechanischem Drehwinkel und elektrischei Signal durch eine nichtlineare Winkelfunktion beschrieben.Rotary encoder for infinite rotation angles known The status of the Technology has a large number of mechanical-electrical working throttle angle sensor systems from which, however, generally the angle of rotation to be determined as a phase amplitude value which is obtained from the sinusoidal supply voltage depending on the angle of rotation. This is the link between the mechanical angle of rotation and the electrical signal described by a non-linear angle function.
Erfindungsgedanke Da die Be zehung zwischen Phasen- und Drehwinkel bei Verwendung von sinusförnigen Speisespannungen eine nichtlineare Winkeliunktion ergibt, wird die Sinuaspeisung (gemäß Skizze i) vermieden und an deren Stelle die Speisung des Widerstandsringes iit Dreieckspannungen vergenommen ( ( Skizze 2 ).Invention concept As the relationship between phase and rotation angle a non-linear angle function when using sinusoidal supply voltages results, the sinua feed (according to sketch i) is avoided and instead the Feeding of the resistance ring with triangular voltages recorded ((sketch 2).
Die zur Speisung des analogen linearen direktproportienalen mechanisch-elektrischen Drehwinkelgebers für unendliche Drehwinkel notwendigen Dreieckspannungen werden in einer Generat@rschaltung gesäß Skizze 3 erzeugt. Hierin synchronisi@rt ein Dreiecksgenerator einen zweiten Dreiecksgenerator so, daß dessen Phasenverschiebung in Bezug auf den ersten 90 beträgt. Zur Stabilisierung der Schaltung wird ein Teil der Ausgangsspannungen des zweiten Generators auf den ersten Generator so zurückgekoppelt, daß eine evenuell auftretende Tritt ii zweiten Dreieckgenerator ausgeregelt wird. Diese Dreieckspannungen lassen sich mit üblichen integrierten elektronischen Bauteilen vergleichsweise leichter darstellen als entsprechend genaue Sinusspannungen, insbesondere zur Speisung relativ niederohmiger Widerstandsringe.The one for feeding the analog linear direct proportional mechanical-electrical Angle of rotation encoder for infinite angles of rotation necessary triangular voltages generated in a generator circuit according to sketch 3. A triangular generator is synchronized here a second triangle generator so that its phase shift with respect to the first 90 is. Part of the output voltages is used to stabilize the circuit of the second generator is fed back to the first generator so that a possibly occurring step ii second triangle generator is regulated. These triangular voltages can be comparatively easier with conventional integrated electronic components represent as correspondingly accurate sinusoidal voltages, especially relative to the supply low resistance rings.
Als Drehwinkelkriterium tritt die Phasenverschiebung des pesitiven Nulldurchgangs der Ausgangsspannung am Achleifer, bezogen auf den entsprechenden Nulldurchgang der Dreieckspannung an eines der vier Speisepunkte, vorzugsweise Speisepunkt 1, aui. Mit bekannten Mitteln sind daraus beliebige Darstellungsferien zur Ausgabe des Drehwinkels herstellbar. Skizze 4 veranschaulicht eine beispielsweise erfindungsgemäße Anordnung.The phase shift of the positive occurs as a criterion for the angle of rotation Zero crossing of the output voltage on the axle wiper, based on the corresponding Zero crossing of the triangular voltage at one of the four feed points, preferably feed point 1, aui. With known means, any display holidays are available for output the angle of rotation can be produced. Sketch 4 illustrates an example according to the invention Arrangement.
Es bleibt vorbehalten, die ii Beispiel sowohl elektrischringförmig wie mechanisch-ringförmig derart abzuwandeln, daß die vier Widerstände mechanisch linear oder @@@ aui einer beliebigen Kurve angeordnet sind, während sie Jedech elektrisch nach wie vor im Kreis geschaltet sind und entsprechend gespeist werden. Sinngemäß erfolgt die Abtastung entlang der xeebanisehen Anordnung der Wider -stünde ( Skizze 5 ).It is reserved to the ii example both electrically ring-shaped how to modify it mechanically-ring-shaped in such a way that the four resistances are mechanically linear or @@@ aui any curve, while they Jedech electrically are still connected in a circle and are fed accordingly. Analogous the scanning takes place along the xeebani arrangement of the resistors (sketch 5).
