After the readout unit 6 has completely received all data, an immediate interruption of the electrical power supply 18 by the readout unit 6 can be made, which leads to an immediate shutdown of the counting unit 3 and thus an interruption of the data coupling 12. In the de-energized state, the selected memory mark is automatically set to busy, so that a further data transmission 13 is no longer possible and data can no longer be influenced outside of the counting unit 3. Alternatively, in the case of a permanent power supply to the counting unit 3, a coordinated decoupling procedure between the counting unit 3 and the read-out unit 6, and then the counter 3 puts itself into a low-consumption mode.
  • FIG. 5 shows an overview drawing of the assignment function 21 with regard to the transmitted reduced data record 20 and the standardized data record 19, in accordance with the specifications of the relevant technical standard or standard. It is considered advantageous in the context of the present invention that only the most necessary data in a reduced amount of data 20 is transmitted to the read-out unit 6 (not shown in FIG. 5) by the counting unit 3 (not shown in FIG. 5).
  • This data includes the data determined at runtime, such as meter reading and status. Also required are the counter data such as counter number, unit, decimal places of the meter reading, medium, manufacturer and other standard or standard-dependent information.
  • the read-out unit 6 contains the standardized data set 19 on which the respective relevant technical standard or standard is based, and assigns the data of the reduced data quantity 20 to the standardized data record 19 via a predefined assignment function 21.
  • the assignment function 21 can be permanently implemented in the read-out unit 6 and possibly also contains further data and information which are necessary for the assignment or completion of the standardized data record 19 by means of the reduced data quantity 20.
  • the readout unit 6 possibly in conjunction with other data processing devices and networks, dynamically determine the reduced amount of data 20 and dynamically generate the assignment function 21 by means of external databases and thus complete the reduced amount of data 20 in relation to the standardized data record 19.

Abstract

L'invention concerne un compteur pourvu d'un élément de comptage électronique, encapsulé hermétiquement, qui comporte au moins une unité de comptage destinée à déterminer des états de compteur. Le compteur électronique, encapsulé hermétiquement, comporte une mémoire de données destinée à mémoriser les états de compteur et l'unité de comptage comporte une antenne de forme d'antenne définie, et au moins une unité de lecture, destinée à lire les états de compteur dans la mémoire de données, est disposée à l'extérieur de l'élément de comptage électronique encapsulé hermétiquement. L'invention concerne en outre un procédé de détermination d'états de compteur et de transmission sans fil d'énergie électrique. La forme de l'antenne de l'unité de lecture est identique à la forme de l'antenne de l'unité de comptage. Le positionnement congruent et prédéterminé de l'antenne de l'unité de lecture par rapport à l'unité de comptage garantit une alimentation sans fil efficace de l'unité de comptage par rayonnement électromagnétique par l'unité de lecture et, indépendamment de cela, un couplage de données sans fil stable pour déterminer les états de compteur entre l'unité de comptage et l'unité de lecture.
