Title (EN) ELECTRIC MONITORING OF SURFACES, IN PARTICULAR THE BOUNDARY SURFACES OF SPORTS GROUNDS
(FR) SURVEILLANCE ELECTRONIQUE DE SURFACES, NOTAMMENT DES SURFACES DE DEMARCATION DE TERRRAINS DE JEU
Abstract:
(EN) Electronic monitoring of surfaces, in particular the boundary surfaces of sports grounds, is effected by means of surfaces superimposed at a distance apart in the monitoring region, at least one of which is flexible. When an object impinges on the contact surfaces, electrical contact is established between the surfaces and an electric and/or acoustic signal is generated. One contact surface is a resistor surface having constant surface resistance and the other contact surface is a conductive surface. A supply voltage is applied to at least two ends of the resistor surface through a corresponding dropping resistor. For the duration of contact between the contact surfaces, at least two voltage distributors are provided the voltages of which are proportional to the distance between the region of contact and the ends of the resistance path. Since each voltage corresponds to a definite point of impact, it is possible to determine when a ball overshoots a sports ground boundary line as well as the exact position of the ball.
(FR) 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.
