Description

25 30 464 733 Enligt uppfinningen har detta uppnåtts därigenom, att varje styr- punkt har en sändare i fonn av en seriekoppiing av en potentiometer och en strömbrytare, att sändarna är ansiutna me11an ïedarna i en för a11a sändare gemensam likspänningsmatad tvåiedariedning, som är koppiad ti11 apparaten via en mottagare, viïken omfattar en avkännare av spänning samt ett minne för ïagring av en spänning, som understiger ett spän- ningsgränsvärde och som senast mottagits för att tjäna som styrvärde för apparaten. 464 733 According to the invention, this has been achieved in that each control point has a transmitter in the form of a series connection of a potentiometer and a switch, that the transmitters are connected between the conductors in a common voltage-supplied two-wire line which is connected to each transmitter. the device via a receiver, which comprises a voltage sensor and a memory for storing a voltage which is less than a voltage limit value and which was last received to serve as a control value for the device.

Uppfinningen ska11 i det föijande närmare beskrivas med hänvis- ning tiil den bifogade ritningen, på viïken fig. 1 schematiskt visar anordningen enïigt uppfinningen och fig. 2 visar tidsberoendet me11an å ena sidan ïedningsspänningen (heldragen iinje) och å andra sidan styr- spänningen hos en instä11bar apparat (mottagarutgången) under styrsek- vensen. s Den i fig. 1 visade kretsen ofattar en spänningsdeïarkrets, vars ena förgrening består av ett motstånd R1 qch vars andra förgrening består av ett antai paralïeiikoppiade potentiometrar P1, P2, PN, viïka är förbundna med en strömbrytare K. Lämpïigen väijes strömbryta- ren K i form av en omkoppiare, som stannar kvar i stängt ïäge endast vid manue11 påverkan och som öppnar av egen kraft, så snart styrningen upphör. En sådan kombination av strömbrytare och potentiometer består av en membranpotentiometer, där inkoppiingen sker genom intryckning av membranet på en förutbestämd punkt, varvid samtidigt tryckpunkten be- ' stämmer instäïiningsvärdet hos en potentiometer. meterströmbrytare är tiiigängiiga på marknaden.The invention will be described in more detail below with reference to the accompanying drawing, in which Fig. 1 schematically shows the device according to the invention and Fig. 2 shows the time dependence between on the one hand the supply voltage (solid line) and on the other hand the control voltage of a adjustable device (receiver output) during the control sequence. The circuit shown in Fig. 1 comprises a voltage divider circuit, one branch of which consists of a resistor R1 and whose second branch consists of a number of potentiometers P1, P2, PN, which are connected in parallel, which are connected to a switch K. The switch K is suitably connected. in the form of a switch, which remains in closed position only under the influence of manue11 and which opens by its own power, as soon as the control ceases. Such a combination of switch and potentiometer consists of a diaphragm potentiometer, where the coupling takes place by depressing the diaphragm at a predetermined point, the pressure point at the same time determining the set value of a potentiometer. meter switches are available on the market.

Dyiika potentio- Anordningen är ansïuten tili en instäilbar apparat 2 via en mot- tagare 1.The potential is the device connected to an adjustable device 2 via a receiver 1.

Mottagaren 1 har ett avkänningsorgan för förutbestämd gränsspän- ning, som är anordnat att bestämma den övre gränsen Ur för ett accep- tabeit instäïïningsområde, såsom visas i fig. 2. Mottagaren 1 är också försedd med ett minne, i viïket 'lagras en spänning som understiger gränsspänningen och som senast erhåliits från anordningens potentiome- 10 15 20 464 733 ' terförgrening för att tjäna som styrvärde för en inställbar apparat 2.The receiver 1 has a sensing means for a predetermined limit voltage, which is arranged to determine the upper limit Ur for an acceptable setting range, as shown in Fig. 2. The receiver 1 is also provided with a memory, in which a voltage is stored which below the limit voltage and most recently obtained from the potentiometer branch of the device to serve as a control value for an adjustable device 2.

Mottagaren 1 är vidare försedd med en avkännare, som är anordnad att avkänna spänningsändringstakten i anordningens potentiometerförgrening med påföljd att styruteffekten hos mottagaren följer sin styringång endast när spänningsändringstakten understiger ett förutbestämt värde.The receiver 1 is further provided with a sensor, which is arranged to sense the voltage change rate in the potentiometer branch of the device with the consequence that the control output power of the receiver follows its control input only when the voltage change rate is below a predetermined value.

Inställning från en av styrpunkterna sker på följande sätt: Om apparaten 2 skall ställas in, slås strömbrytaren K för den motsvarande potentiometern till. Motståndet R1 och den med den tillslagna ström-_ brytaren förbundna potentiometern åstadkommer spänningsdelning och led- ningsspänningen faller snabbt (<1 1 ms) till ett av spänningsdelningen bestämt värde. En inställbar apparat följer ledningsspänningen med en fördröjning på ca 1 ms, förutsatt att ledningsspänningen ligger under Ur och att derivatan eller ändringstakten för spänningen är mindre än Ur/2 V/s. _ När potentiometern regleras, kommer spänningsändringstakten att ligga på ett avsevärt lägre värde än det ovan angivna, varigenom styr- spänningen hos en inställbar apparat börjar följa ledningsspänningen.Setting from one of the control points is as follows: If the device 2 is to be set, the switch K for the corresponding potentiometer is switched on. The resistor R1 and the potentiometer connected to the on / off switch cause voltage division and the line voltage drops rapidly (<1 1 ms) to a value determined by the voltage division. An adjustable device follows the line voltage with a delay of approx. 1 ms, provided that the line voltage is below Ur and that the derivative or rate of change of the voltage is less than Ur / 2 V / s. When the potentiometer is regulated, the voltage change rate will be at a considerably lower value than that specified above, whereby the control voltage of an adjustable device begins to follow the line voltage.

När en potentiometers strömbrytare åter öppnas, ökar lednings- spänningen snabbt över Ur och mottagarens 1 minne lagrar ett nytt in- ställningsvärde, som motsvarar värdet hos ledningsspänningen omkring 1 ms innan strömbrytaren öppnas.When a potentiometer's switch is opened again, the line voltage increases rapidly across the clock and the receiver's 1 memory stores a new setting value, which corresponds to the value of the line voltage about 1 ms before the switch is opened.
