Description

BESCHREIBUNGDESCRIPTION

Lichtschranken-Geschwindigkeits-Meßsystem mit 5 Lichtschranken auf zwei Ebenen.Light barrier speed measuring system with 5 light barriers on two levels.

Stand der TechnikState of the art

Lichtschranken-Meßsysteme üblicher Bauart haben eine Messebene mit 3 Lichtschranken.Light barrier measuring systems of standard design have a measuring plane with 3 light barriers.

Hierbei werden die Lichtstrahlen über der Fahrbahn durch ein vorbeifahrendes Fahrzeug nacheinander unterbrochen und ein Kurzzeitrechner stellt die gefahrene Geschwindigkeit fest. Zur Kontrolle der Geschwindigkeit werden zwei Wegstrecken in einer Ebene im Verhältnis 1 : 2 miteinander verglichen. Hierbei können jedoch Fehlabtastungen durch Vertikal schwingungen, speziell bei modernen und schrägen Fahrzeugkonturen, auftreten und zu falschen Messergebnissen führen.
Diese Erkenntnisse sind in Gutachten von Sachverständigen belegt.The light beams above the road are interrupted one after the other by a passing vehicle and a short-term computer determines the speed driven. To check the speed, two distances on one level are compared with each other in a ratio of 1:2. However, incorrect scanning can occur due to vertical vibrations, especially with modern and slanted vehicle contours, and lead to incorrect measurement results.
These findings are documented in expert reports.

Problemproblem

Der im Anspruch angegebenen Erfindung liegt das Problem zugrunde, ein Meßsystem zu schaffen, welches Fehlmessungen durch Vertikalschwingungen erkennen kann.The invention specified in the claim is based on the problem of creating a measuring system which can detect incorrect measurements caused by vertical vibrations.

Erfindunginvention

Das Lichtschranken-Geschwindigkeits-Meßsystem tastet die Fahrzeuge an der Front auf zwei Meßebenen ab.The light barrier speed measuring system scans the vehicles at the front on two measuring levels.

Die 1. Messebene mit 3 Lichtschranken misst zwei Wegstrecken, die im Verhältnis 1 : 2 miteinander verglichen werden.The first measuring level with 3 light barriers measures two distances, which are compared with each other in a ratio of 1:2.

Die 2. Messebene ist so angeordnet, daß sich zwischen den einzelnen Lichtschranken der beiden Ebenen ein Parallelogramm bilden läßt. Dadurch ergeben sich Kontroll strecken zwischen den Lichtschranken 2 und 3 und 4 und 5The 2nd measuring plane is arranged in such a way that a parallelogram can be formed between the individual light barriers of the two planes. This results in control distances between the light barriers 2 and 3 and 4 and 5

Darstellung der ErfindungDescription of the invention

Ein Ausführungsbeispiel der Erfindung wird anhand der Figur erläutert.An embodiment of the invention is explained with reference to the figure.

Lichtschranken bezeichnet Meßstrecken bezeichnet Kontroll strecken bezeichn.Light barriers referred to as measuring sections referred to as control sections.

Claims (1)

SCHUTZANSPRUCHEPROTECTION CLAIMS Lichtschranken-Geschwindigkeits-Meßsystem, welches 5 Lichtschranken, verteilt auf 2 Ebenen, aufweist.Light barrier speed measuring system, which has 5 light barriers, distributed on 2 levels. Dadurch gekennzeichnet, daß sich die 5 Lichtschranken auf zwei Ebenen verteilen, wobei eine Ebene 3 Lichtschranken, die andere Ebene 2 Lichtschranken aufweist.Characterized in that the 5 light barriers are distributed over two levels, with one level having 3 light barriers, the other level having 2 light barriers. Die zwei Messebenen zueinander sind so ausgerichtet, daß sich zwischen den Lichtschranken 1, 2, 3 und 4 sowie zwischen den Lichtschranken 2, 3, 4 und 5 ein gleiches Parallelogramm bilden läßt.The two measuring planes are aligned to each other in such a way that an identical parallelogram can be formed between the light barriers 1, 2, 3 and 4 as well as between the light barriers 2, 3, 4 and 5.
