Abstract
Description
Die Erfindung bezieht sich auf eine spezielle Schaltungsanordnung eines bestimmten Sicherheitsdrahtes für die Herstellung von Sicherheitszäunen und die Erstellung einer Nachfeldsicherung aus diesem Sicherheitsgeflecht.The invention relates to a special circuit arrangement of a specific security wire for the production of security fences and the creation of a post-field protection from this security network.
Nach dem Stand der Technik werden alle physikalisch auswertbaren Detektionsmöglichkeiten angewandt. Die Vielzahl der Möglichkeiten sind Detektionen die nicht mechanisch drahtgebunden sondern auf dem Gebiet der nieder- bis hochfrequenten Basis arbeiten. Alle diese Detektionen von Schall bis Laserlicht können auch durch andere Ereignisse, die nicht von einem denkenden Täter - also von einem Menschenverursacht werden, ausgelöst werden. Das sogenannte Ausfiltern von Objekten kleinerer Grössnordnungen als ein menschlicher Körper ist als fragwürdig zu bezeichnen.Ein rein elektromechanisch arbeitendes System scheiterte in der Vergangenheit an einer ganzen Reihe von technisch in der damaligen Zeit nicht lösbaren, realisierbaren Problemen ( 1961 , England Pat.Nr.978 051 ). Es sind in diesem Patent einige theoretische Möglichkeiten angezeigt, die jedoch technisch nicht anwendbar sind.Ein Widerstandsdraht als Seele des Drahtes für das Geflecht war angezeigt, jedoch nicht die Probleme mit der Temperaturdrift bei Anwendung im Freigelände (Tag-Nacht,Sommer-Winter usw.) sowie an den Problemen der Geflechtsherstellung, der bei bekannten Herstellverfahren für Geflechte erforderlichen vielen Verbindungen und deren Dichtigkeit gegen Wasser und Erdfeuchtigkeit. Alle diese Probleme waren nicht gelöst und auch keine Wege zur Lösung aufgezeigt.According to the prior art, all physically evaluable detection options are used. The multitude of possibilities are detections which do not work mechanically wired but work in the area of the low to high frequency basis. All of these detections from sound to laser light can also be triggered by other events that are not caused by a thinking perpetrator - i.e. by a human. The so-called filtering out of objects of smaller sizes than a human body can be described as questionable. In the past, a purely electromechanical system failed due to a whole series of realizable problems that were technically unsolvable at the time (1961, England Pat. No. 978 051). There are some theoretical possibilities indicated in this patent, which, however, are not technically applicable. A resistance wire as the core of the wire for the braid was indicated, but not the problems with the temperature drift when used outdoors (day-night, summer-winter etc. ) and the problems of braid production, the many connections required in known production processes for braids and their tightness against water and earth moisture. All of these problems were not resolved and no ways of solving them were shown.
Der Gegenstand dieser Anmeldung beschreibt eine Ergänzung zu einer Reihe in den letzen Jahren von uns zum Schutz angemeldeter Lösungen obiger Probleme, die wir im Folgenden kurz zur besseren Verständlichkeit erläutern.The subject matter of this application describes a supplement to a number of the solutions of the above problems registered by us in the last few years, which we will briefly explain below for better understanding.
Die Vermeidung von Fehlalarmen ist für jeden, der sich mit Sicherheitsproblemen befasst, oberster Grundsat Jeder Fehlalrm stellt die Tauglichkeit einer Sicherungsanlage erheblich in Zweifel.Avoiding false alarms is the top priority for anyone who deals with security problems. Every false alarm seriously questions the suitability of a security system.
Für die Herstellung eines Zaungeflechtes wird ein Sicherheitsdraht nach DBPa 28.56819.6 gemäß Zeichnung (1) angewandt. Dieser Sicherheitsdraht enthält in der durch eine Stahlarmierung geschützten Seele zwei Widerstands- und zwei Kupferdrähte äusserlich gleicher Dimension und Beschaffenheit, die nach einer Schaltungsanordnung nach DBPa.30.06999.9 gemäss Zeichnung Nr.(2) an eine für Sicherheitszwecke nach DBPa 28.34957.7 gemäß Zeichnung Nr.(3) geeignete Brückenschaltung angeschlossen ist.A safety wire according to DBPa 28.56819.6 in accordance with drawing (1) is used to manufacture a fence mesh. This safety wire contains in the core protected by a steel armor two resistance and two copper wires with the same external dimensions and properties, which according to a circuit arrangement according to DBPa.30.06999.9 according to drawing no. (2) to one for safety purposes according to DBPa 28.34957.7 according to the drawing No. (3) suitable bridge circuit is connected.
Die im Sicherheitsdraht enthaltenen zwei Widerstandsdrähte A1 und A2 stellen je einen Brückenzweig der Brükkenschaltung dar.Damit wird die Änderung durch Aussentemperatur automatisch kompensiert, da sich ja beide Brükkenzweige gleichzeitig ändern und somit die Brücke immer im Gleichgewicht bleibt. Die beiden Widerstandsdrähte sind unter Zuhilfenahme der beiden Kupferdrähte B1 und B2 gemäß der Schaltungsanordnung nach Zeichnung (2) gegenläufig geschaltet, so dass ein Überbrückungsversuch in jedem Fall sofort zum Alarm führt.The two resistance wires A1 and A2 contained in the safety wire each represent a bridge branch of the bridge circuit, which automatically compensates for the change due to the outside temperature, since both bridge branches change at the same time and the bridge always remains in balance. The two resistance wires are connected in opposite directions with the aid of the two copper wires B1 and B2 according to the circuit arrangement according to drawing (2), so that a bridging attempt in any case immediately leads to an alarm.
Zum Schutz gegen Überklettern des Zaunes befindet sich im oberen Drittel des Zaunpfostens E in Zeichnung (4) ein federnd gelagerter Schalter A,B,C,D in Zeichnung (4) nach DBPa 27.17906.2 der bei seitlicher oder vertikaler Belastung einen Magnetschalter D (4) auslöst. Diese Auslösung erfolgt mit Hebelarm(Ausleger) A (4) über die Kippkante B (4) und Taststift mit Rückholfeder C (4) .To protect against climbing over the fence, there is a spring-mounted switch A, B, C, D in drawing (4) according to DBPa 27.17906.2 in the upper third of the fence post E in drawing (4) according to DBPa 27.17906.2, which has a magnetic switch D (for lateral or vertical loading) 4) triggers. This release takes place with lever arm (arm) A (4) over the tipping edge B (4) and stylus with return spring C (4).
Zum Schutz gegen Unterkriechen ist das Geflecht eingegraben (Auoh Bachläufe sind schützbar) gemäß Zeichnung (5).To protect against crawling under, the braid is buried (Auoh streams can be protected) according to drawing (5).
Die für Objekte höchster Sicherheitsanforderung erforderliche Nachfeldsicherung (z.Z. 5 Meter) wird ebenfalls mit einem Geflecht nach DBPa.30.10522.7 gemäß Zeichnung (6) das nach einem besonderen Flechtverfahren ebenso wie alle anderen Zaungeflechte im Endlosverfahren geflochten wird und dadurch nur über einen Anschluss an Anfang und. Ende der jeweiligen M te angeschlossen werden muß, ausgerüstet.The post-field protection required for objects with the highest security requirements (currently 5 meters) is also provided with a braid according to DBPa.30.10522.7 according to drawing (6), which is braided using a special braiding process, like all other fencing braids, in an endless process and therefore only via a connection at the beginning and. Must be connected at the end of the respective period.
Dieses Gflecht wird in Schräglage vom äusseren Zaun A (6) über eine Feder D (6) gegen den Punkt G (6), der auch als Zweitzaun ausgeführt sein kann, abgespannt. Das Zugseil oder die Zugstange F (6) ist von der Mitte des GeflechtesThis mesh is braced in an inclined position from the outer fence A (6) via a spring D (6) against the point G (6), which can also be designed as a second fence. The pull rope or pull rod F (6) is from the middle of the braid
E (6) zum Ausleger C (6) mechanisch verbunden. Dadurch wird bei vertikaler Belastung durch einen Täter der im Pfosten A (6) montierte Auslegerschalter B (6) betätigt und Alarm ausgelöst.E (6) mechanically connected to the boom C (6). This causes the boom switch B (6) mounted in the post A (6) to be actuated and an alarm to be triggered in the event of vertical loading by an offender.
Das gesamte System ist einfach, in Herstellung und Betrieb problemlos und bei handwerklich guter Arbeit fehlalarmfrei.The entire system is simple, easy to manufacture and operate and, with good workmanship, free of false alarms.
Da der grösste Teil der einzelnen Teile des Systems bereits durch Auslegungen des deutschen Patentamtes als Stand der Technik gelten, können wir nur die Prioritäten der Anmeldungen DBPa.28.56819.6 vom 25.2.80 und DBPa.30.10522.7 vom 19.3.80 als Schutzansprüche anführen.Since the majority of the individual parts of the system are already considered to be state of the art due to interpretations by the German Patent Office, we can only cite the priorities of applications DBPa.28.56819.6 from February 25, 80 and DBPa.30.10522.7 from March 19, 1980 as protection claims .
