Description

Digitale potentiometer, voorzien van een motor en een absolute hoekverdraaiingsopnemer.Digital potentiometer, equipped with a motor and an absolute angle rotation sensor.

De uitvinding heeft betrekking op een dgitaie potentiometer, uitgevoerd ais een motor(5) waarvan de as(6) direkt dom de gebruiker gedraaid kan worden, zonder mechanische overbrenging. Door middel van een absolute optische hoekverdraaüngsopnemer(1,3,4) en een microcontroler(2) wordt de stand van de as als numerieke waarde aan een wMekeurig apparaat doorgegeven of kan dat apparaat de mterocontroier de opdracht geven de as naar een bepaalde stand te draaien.The invention relates to a digital potentiometer, constructed as a motor (5), the shaft (6) of which can be turned directly by the user, without mechanical transmission. By means of an absolute optical angle displacement sensor (1,3,4) and a microcontroller (2) the position of the axis is passed on as a numerical value to a random device or that device can instruct the mterocontroller to move the axis to a certain position. to turn.

Door het gebruik van de absolute hoekopnemer en een "inteHgenté” microcontroller voor de A/D conversie en aansturing van de motor kunnen allerlei extra eigenschappen aan de potentiometer toegevoegd worden, waarvan enkele zijn: -Als de gebruiker aan de as draait kan de microcontroller een -instelbare- tegenkracht geven door de motor de andere kant op té sturen.By using the absolute angle sensor and an "inHgenté" microcontroller for the A / D conversion and control of the motor, all kinds of extra properties can be added to the potentiometer, some of which are: -When the user turns the shaft, the microcontroller can -adjustable- counter force by steering the motor in the opposite direction.

•Hierdoor is het dan ook mogelijk om kikstanden, in aantal en plaats, vrij te kiezen. -De gebruiker kan de potentiometer vast zetten op een zelf te definiëren plaats.• This makes it possible to freely choose kick positions, in number and location. -The user can lock the potentiometer in a place that can be defined by himself.

-etc.-etc.

Een soortgelijk systeem bleek al bekend te zijn uit het Octrooi nr WO 93/08517.A similar system has already been found to be known from Patent No. WO 93/08517.

De uitvinding maakt echter gebruik van een fundamenteel andere werking waardoor miniaturisering, kostenbeheersing en verbetering van de werking zeer goed realiseerbaar zijn.However, the invention makes use of a fundamentally different operation, whereby miniaturization, cost control and improvement of the operation are very feasible.

Er wordt namelijk gebruik gemaakt van een absolute optische (analoge) hoekverdraaiingsopnemer die bestaat uit de volgende componenten: een rode LED(4), en een lichtsensor(l) die lichthoeveelheid meet met daar tussenin een transparante film(3) met een cirkel die van 0 tot 360 graden een in dichtheid oplopend puntjes-patroon bevat (ongeveer 0 tot 95 %). Als deze film aan de as wordt bevestigd kan de hoekverdraaiing eenvoudig bepaald worden door de doorgelaten lichthoeveelheid te meten. Hierdoor kan een meetbereik van iets minder dan 360 graden gebruikt worden. Een belangrijk voordeel van deze opnemer is dat de bedrijfszekerheid veel groter is dan wanneer gebruik wordt gemaakt van een relatieve digitale encoder, op elk willekeurig tijdstip kan de asstand gemeten worden zonder afhankelijkheid van wat eerder gemeten of gebeurd is.This is because an absolute optical (analog) angle rotation sensor is used, consisting of the following components: a red LED (4), and a light sensor (l) that measures the quantity of light with a transparent film (3) with a circle in between. 0 to 360 degrees contains a density ascending dot pattern (approximately 0 to 95%). When this film is attached to the shaft, the angular rotation can be easily determined by measuring the transmitted light quantity. This allows a measuring range of just under 360 degrees to be used. An important advantage of this sensor is that the reliability is much greater than when using a relative digital encoder, the axis position can be measured at any time without dependence on what has previously been measured or happened.

De praktische uitvoering.The practical implementation.

In tekening 1 is de mechanische uitvoering uitgeiegd en in tekening 2 staat het elektrische schema beschreven van het volledig werkende prototype. De mogelijkheden van dit prototype zijn: -160 stapjes (-80 tot +80) op een draaiing van 300 graden.In drawing 1 the mechanical version is explained and in drawing 2 the electrical diagram of the fully working prototype is described. The possibilities of this prototype are: -160 steps (-80 to +80) on a rotation of 300 degrees.

-Klikstanden bij -80 en +80.-Click positions at -80 and +80.

•Naar keuze kunnen daarnaast nog 0,1 (vrije keuze van de plaats, meestal in het midden), 10,20 of 40 klikstanden bestaan.• Optionally, there can also be 0.1 (free choice of place, usually in the middle), 10.20 or 40 click positions.

-Vier keuzemogelijkheden voor de tegenkracht bij draaiing aan de as: uit, 1,2 of 3. Bij gebruik van een grotere tegenkracht moet dan wel rekening worden gehouden met een grotere hysterese die de microcontroller toepast -Een gemiddelde insteltijd van 200 ms wanneer de motor de as naar een bepaald punt draait-Four selections for the counter-force on rotation of the shaft: off, 1,2 or 3. When using a larger counter-force, a greater hysteresis applied by the microcontroller must be taken into account. - An average setting time of 200 ms when the motor is the axis rotates to a certain point
