  • the fuzzy logic controller only corrects the difference between the desired substance conductance and the actual substance conductance when it has determined the actual substance conductance to be sufficiently stable. This determination is carried out by always forming the mean value from the current point in time from the last x (e.g. 16) measured values of the actual substance conductance and determining a bandwidth which includes a % (e.g. 10%) above and b % (e.g. 10%) is below the mean. If from the last x measurements used for averaging, y (eg 10) values are within the range, the actual substance conductance is considered to be sufficiently stable.
  • the sampling rate is, for example, 1 measurement/sec. This procedure is in the graph of 2 shown.
  • the second algorithm in the fuzzy logic controller takes care of the amount of substance that needs to be dosed. This is done on the basis of the duration of the delivery of a test dose, which has a certain time value "X", eg 250 ms. After the new actual substance conductance of the washing liquor has stabilized, the difference between the target substance conductance and the actual substance conductance is used to calculate the time still required to dispense the substance using a final calculation. This enables very precise dosing and precise attainment of the target substance conductivity. Since this works with every dosing process, any changes in water pressure, temperature, consistency of the substance and the level of the substance in the container are taken into account.

  • This information includes a substance identification and substance characteristic data, such as a standard substance conductivity value, a standard water conductivity value of the water to be supplied to the substance, a standard water hardness of the water to be supplied to the substance and a compensation factor for deviations in the standard substance conductivity value between the standard -Water hardness and the actual water hardness.
  • the information read by means of the RFID reader 2h, 3h is forwarded to the control algorithm 22a, 23a and taken into account by it as a control parameter in the control.

Système de dosage selon la revendication 13 ou 14, caractérisé en ce que le régulateur à logique floue calcule le dosage de la substance à délivrer sur la base de la durée de la délivrance d'un dosage test, en calculant, à partir de la différence entre la valeur de consigne de conductance de la substance et la valeur réelle de conductance de la substance, au moyen d'un calcul final, et à partir de la durée de la délivrance du dosage test, la durée encore nécessaire de délivrance actuelle de la substance.
  16. Système de dosage selon l'une des revendications précédentes, caractérisé en ce que le distributeur comporte, à proximité de son admission de substance, un lecteur RFID (2h, 3h) permettant de lire des informations contenues dans une étiquette RFID (24c, 25c) fixée au récipient (24, 25), les informations comprenant de préférence une identification de la substance, telle qu'un code de produit et de pays, et des données caractéristiques de la substance, telles qu'une valeur standard de conductance de substance, une valeur standard de conductance de l'eau d'alimentation de la substance, une dureté standard de l'eau d'alimentation de la substance ainsi qu'un facteur de compensation pour la valeur standard de conductance de la substance en cas d'écart entre la dureté d'eau standard et la dureté d'eau réelle.
