Description
sentiich herabgesetzt worden. Durch Beschichtung der Eiektroden mit wasserundurchlässigem Kunststoff ist die Anlage feuchtigkeitsunempfindlich. Es wird somit eine hohe Betriebssicherheit erreicht. Die Anwendung des erfindungsgemäßen Verfahrens erstreckt sich nicht nur auf Raum- und Gebäudesichorungsanlagen, wie z. B. Warenhäuser mit großen Verkaufsflächen, Lagerhallen, Betriebsräume usw., sondern auch auf Überwachungsanlagen für Freigelände. sentiich has been belittled. By coating the electrodes with waterproof plastic the system is insensitive to moisture. A high level of operational reliability is thus achieved. the Application of the method according to the invention does not only extend to room and building security systems, such as B. Department stores with large sales areas, warehouses, operating rooms, etc., but also on monitoring systems for outdoor areas.
Weitere Anwendungsfdlle bestehen beispielsweise darin, das Verfahren zu Verkehrszählzwecken oder als Anwesenheitsindikator für Personenkraftwagen in Parkhäusern einzusetzen.Other applications include, for example, the method for traffic counting purposes or to be used as a presence indicator for passenger cars in parking garages.
Die Erfindung soll nachstehend an Hand des Ausführungsbeispiels einer Raumsicherungsanlage näher erläutert werden.The invention is to be described in more detail below using the exemplary embodiment of a room security system explained.
In dem zu überwachenden Raum sind eine oder mehrere Detektorelektroden auf dem Fußboden unter einer Abdeckung, z. B. einem Teppich ausgelegt. Eine andere Möglichkeit besteht darin, Teile des Fußbodens z. B. PVC-Böden selbst als Detektorelektroden auszubilden. Die Geometrie der Elektroden kann dem zu überwachenden Gebiet angepaßt werden, d. h. die Wirkungsweise des erfindungsgemäßen Verfahrens ist von der Form der Elektroden weitgehend unabhängig.In the room to be monitored, one or more detector electrodes are on the floor below a cover, e.g. B. designed a carpet. Another possibility is to use parts of the Floor z. B. to train PVC floors themselves as detector electrodes. The geometry of the electrodes can be adapted to the area to be monitored, d. H. the mode of action of the invention The method is largely independent of the shape of the electrodes.
Das Eindringen von Personen in den zu überwachenden Raum führt infolge der Deformation der Elektrodenumhüllung durch das Gewicht der eindringenden Person zu einer elektrostatischen Potentialänderung auf der Elektrode gegenüber einem Referenzpotential durch die Freisetzung von insbesondere Oberflächenelektronen, die das Potential der Detektorelektrode verändern.The intrusion of people into the monitored area leads to the deformation of the Electrostatic potential change due to the weight of the intruding person on the electrode compared to a reference potential due to the release of particular Surface electrons that change the potential of the detector electrode.
Durch das dem Effekt angepaßte Verhalten der nachgeschalteten Auswertelektronik, deren differenzierendes Verhalten lediglich eine Veränderung des Elektrodenpotentials bewertet, ist es unerheblich, mitDue to the behavior of the downstream evaluation electronics adapted to the effect, their differentiating Behavior only evaluates a change in the electrode potential, it is irrelevant with
