Definitions

  • DE-OS 25 27 465 provides conductors embedded in the floor behind the line to be monitored in each case, which are separated from one another by layers, for example by an air gap. In the event of an impact of the play equipment (ball), the upper layer of the ladder is against the underlying position pressed, whereby a signal can be triggered.
  • DE-OS 32 41 468 also suggests such monitoring and uses strip-shaped signaling elements for this purpose, which are laid in the "off" area along the lines to be monitored and consist of hollow plastic profiles in which metal foils are arranged spaced apart as contact foils and are electrically conductively contacted when an object hits.
  • the invention is based on a method according to the preamble of claim 1, as has become known for example from DE-OS 25 27 465 or DE-OS 32 41 468. It is based on the task of proposing a simple method with which it is possible in all or almost all cases that occur is to monitor all mirror lines with sufficient security and accuracy even if several impact events take place simultaneously or with the least delay. For example, it should be possible, in particular, to correctly identify a ball as "good” that strikes near an "off” line within the field while the player is entering the "off” zone. It should also be possible to recognize a ball as "out”, even though the player is also in the monitored "out” area. This is not even possible with the previously known methods.
  • both ends of the strip-shaped resistance surface or resistance track 10 are each supplied with a supply voltage U 1 or U 2 .
  • This application takes place with the respective interposition of a series resistor R 1 or R 2 .
  • R L R L1 + R L2.
  • R L R L1 + R LK + R L2
  • Fig. 6 a special case is shown, which differs from that shown in FIG. 5 in that the player is not standing still on the contact surface arrangement 10/11, but bounces with his foot there, i.e. the contact surface arrangement is constantly loaded and in rapid change relieved again. Such bouncing can occur especially when sliding ("rubbing the floor").
  • the resistance track 1 is laid congruent with the field line, the resistance track 2 at a short distance of eg 1-2 cm next to it in the "off".
  • the two strips 10, 10 'can have a common conductor track 11 be highlighted.
  • both the resistance path 1 and the resistance path 2 are each connected in the manner described, in particular according to FIG. 1. In this way it can be determined whether the ball has touched the resistance track 1 and / or the resistance track 2.
  • Part 10 'of the contact surface arrangement can itself be designed as a playing field boundary line and can hold a surface which is adapted to the space.
  • the sensor arrangement can also be inserted or the like in pockets prepared in the floor. be or, for example, be incorporated into the floor during weaving or tufting.
  • 14 schematically illustrates the electronic evaluation of each line using a "double sensor strip". Two double voltage controls must be evaluated for each line to be monitored. Line 1 is thus assigned two arrangements A 1 and B 1 approximately corresponding to FIG. 1, line 2 two analog arrangements A 2 and B 2 etc.
  • the invention can be used to monitor the crossing of lines within relatively narrow band zones, but also the impact of an object over a larger area. For example, imagine a throwing game in which a ball is thrown against a wall surface, but is not held there but bounces back.
  • at least three ends, corners or edge zones of the resistance surface can be supplied with a supply voltage U 1 to U 3 via a series resistor R 1 to R 3 , so that at least three are kept during the contacting of the contact surfaces
  • Receives voltage divider whose voltage values U X1 to U X3 are proportional to the respective distance of the contacting zone from the connections of the supply voltages U 1 to U 3 .
  • the geometric position of a singular impact event can be determined exactly. If the case occurs that two objects hit the surface to be monitored at the same time and both events are to be identified independently of one another, it is expedient to extend the triple arrangement to a quadruple arrangement, as shown in FIG. 16.
  • the dependencies of the tapped partial voltages U X1 to U X4 between the respective contact point and the feed points can be seen from the simple formulas contained on the drawing sheet in FIG. 16.

Abstract

Afin d'assurer la surveillance électronique de surfaces, notamment des surfaces de démarcation de terrains de jeu, on utilise des surfaces de contact superposées et mutuellement écartées dans la zone de surveillance, dont au moins une est flexible. Sous l'impact d'un objet, les surfaces de contact entrent en contact électriquement conducteur et génèrent un signal électrique et/ou acoustique. Une des surfaces de contact est une surface de résistance à résistance constante de surface et l'autre surface de contact est une surface conductive, une tension d'alimentation étant appliquée à au moins deux extrémités de la surface de résistance à travers des résistances séries respectives. Pendant toute la durée du contact entre les surfaces de contact, on prévoit au moins deux diviseurs de tension dont les valeurs de tension sont proportionnelles à la distance entre la zone de contact et les extrémités de la piste de résistance. Etant donné que chaque valeur de tension correspond à un point d'impact défini, on peut déterminer non seulement le dépassement par la balle d'une ligne de démarcation du terrain de jeu, par exemple, mais aussi sa localisation précise.
