Definitions

  • the device for traffic monitoring can be a “red light monitoring system” for monitoring a traffic light-controlled intersection or, for example, a speed monitoring system with Doppler radar, by means of which the exceeding of a permissible maximum speed is detected.
  • the recording camera can be a photographic camera. However, it can also be, for example, an electronic camera, e.g. a video camera, act in which the image is recorded and stored electronically.
  • Devices for photographic monitoring of traffic light-controlled intersections are known (DE-B 1 078 797). Devices of this type are intended to identify vehicles that enter an intersection during the blocking phase.

Another signal is picked up at the traffic light when the traffic light switches to the blocking phase.
  • a photographic camera is triggered by a control and evaluation unit when a sensor signal appears during the blocking phase, that is, when a vehicle enters the intersection during the blocking phase. The camera then provides a picture on which the vehicle in the intersection and the traffic light can be seen standing on "red”. The vehicle registration number can also be seen on the recording so that the vehicle can be identified.
  • several recordings are usually triggered one after the other at fixed time intervals (DE-C 23 65 331).
  • traffic monitoring devices not only have the purpose of determining violations of traffic rules, but are also intended to have a preventive effect.
  • devices for red light monitoring would have to be installed at a large number of traffic light controlled intersections in the city area. This would require considerable effort both for the installation of the devices and for the evaluation of the recordings made with them.

  • the permanently installed, stationary components are the sensor embedded in the road surface and a housing, which is usually arranged on a column, the sensor being connected to connections in the housing via permanently installed lines.
  • the insert contains the photographic camera, a flash unit and a control and evaluation unit, which controls the functional sequence and links the signals received from the sensor and the traffic light for triggering or not triggering the camera. It can then be used in an irregular sequence in different locations in the respective housing.

  • the blocking phases "red” can be preceded by "yellow phases” of different lengths.
  • the spatial dimensions of intersections and the positions of the sensors to the intersections can be different, which requires different settings of delay times for different locations.
  • an identifier or designation of the place of use must be entered.

Die Erfindung betrifft eine stationäre Vorrichtung zur Verkehrsüberwachung, enthaltend

  • (a) ein am Einsatzort fest installiertes Gehäuse und
  • (b) einen in dem Gehäuse leicht herausnehmbar angeordneten Einsatz mit einer Aufnahmekamera und einer Steuer- und Auswerteeinheit, in welche Daten eingebbar sind, die für den Einsatzort spezifisch sind.

  • (a) a housing permanently installed at the site and
  • (b) an insert which can be easily removed in the housing and has a recording camera and a control and evaluation unit, into which data can be entered which are specific to the place of use.

Die Vorrichtung zur Verkehrsüberwachung kann eine "Rotlichtüberwachungsanlage" zur Überwachung einer ampelgesteuerten Kreuzung oder beispielsweise eine Geschwindigkeits-Überwachungsanlage mit Doppler-Radar sein, durch welche die Überschreitung einer zulässigen Höchstgeschwindigkeit erfaßt wird. Die Aufnahmekamera kann eine photographische Kamera sein. Es kann sich aber auch beispielsweise um eine elektronische Kamera, z.B. eine Videokamera, handeln, bei welcher das Bild elektronisch aufgezeichnet und gespeichert wird.The device for traffic monitoring can be a “red light monitoring system” for monitoring a traffic light-controlled intersection or, for example, a speed monitoring system with Doppler radar, by means of which the exceeding of a permissible maximum speed is detected. The recording camera can be a photographic camera. However, it can also be, for example, an electronic camera, e.g. a video camera, act in which the image is recorded and stored electronically.

Zugrundeliegender Stand der TechnikUnderlying state of the art

Es sind Vorrichtungen zur photographischen Überwachung ampelgeregelter Kreuzungen bekannt (DE-B 1 078 797). Solche Vorrichtungen sollen Fahrzeuge identifizierbar erfassen, die während der Sperrphase in eine Kreuzung einfahren. Zu diesem Zweck ist in der Fahrbahndecke der überwachten Straße kurz vor der Einmündung in die Kreuzung ein Fühler in Form einer Induktionsschleife eingelassen, der auf ein darüberfahrendes Fahrzeug anspricht und ein Fühlersignal liefert. Ein weiteres Signal wird an der Ampel abgegriffen, wenn die Ampel in die Sperrphase schaltet. Eine photographische Kamera wird durch eine Steuer- und Auswerteeinheit ausgelöst, wenn während der Sperrphase ein Fühlersignal erscheint, also ein Fahrzeug bei Sperrphase in die Kreuzung einfährt. Die Kamera liefert dann eine Aufnahme auf welcher das Fahrzeug in der Kreuzung und die Ampel auf "Rot" stehend erkennbar ist. Auf der Aufnahme ist auch das Fahrzeugkennzeichen zu sehen, so daß das Fahrzeug identifiziert werden kann. Zur Erhöhung der Beweiskraft werden üblicherweise mehrere Aufnahmen in festen Zeitabständen nacheinander ausgelöst (DE-C 23 65 331).Devices for photographic monitoring of traffic light-controlled intersections are known (DE-B 1 078 797). Devices of this type are intended to identify vehicles that enter an intersection during the blocking phase. For this purpose, a sensor in the form of an induction loop, which responds to a vehicle traveling over it and supplies a sensor signal, is embedded in the road surface of the monitored street shortly before the junction with the intersection. Another signal is picked up at the traffic light when the traffic light switches to the blocking phase. A photographic camera is triggered by a control and evaluation unit when a sensor signal appears during the blocking phase, that is, when a vehicle enters the intersection during the blocking phase. The camera then provides a picture on which the vehicle in the intersection and the traffic light can be seen standing on "red". The vehicle registration number can also be seen on the recording so that the vehicle can be identified. To increase the evidential value, several recordings are usually triggered one after the other at fixed time intervals (DE-C 23 65 331).

Diese Vorrichtungen haben nicht nur den Zweck, Übertretungen der Verkehrsregeln festzustellen sondern sollen auch präventiv wirken. Es müßten dazu Vorrichtungen zur Rotlichtüberwachung an einer Vielzahl von ampelgeregelten Kreuzungen im Stadtgebiet installiert werden. Das würde einen erheblichen Aufwand sowohl für die Installation der Vorrichtungen als auch für die Auswertung der damit gemachten Aufnahmen erfordern. Aus diesem Grund werden Vorrichtungen zur Verkehrsüberwachung häufig zweiteilig ausgebildet: Sie enthalten am Einsatzort fest installierte Bauteile und einen Einsatz, der an verschiedenen Einsatzorten eingesetzt werden kann. Die fest installierten, stationären Bauteile sind der in die Fahrbahndecke einge lassene Fühler und ein meist auf einer Säule angeordnetes Gehäuse, wobei der Fühler mit Anschlüssen in dem Gehäuse über fest verlegte Leitungen verbunden ist. Der Einsatz enthält die photographische Kamera, eine Blitzgerät sowie eine Steuer-und Auswerteeinheit, welche den Funktionsablauf steuert und die von dem Fühler und der Ampel erhaltenen Signale zur Auslösung oder Nichtauslösung der Kamera verknüpft. Es kann dann ein Einsatz in unregelmäßiger Folge an verschiedenen Einsatzorten in das jeweilige Gehäuse eingesetzt werden. Der Autofahrer weiß dann nicht, in welchem Gehäuse ein Einsatz mit Kamera, Blitzgerät und Steuer-und Auswerteeinheit eingesetzt ist, welche Anlage also betriebsbereit ist.These devices not only have the purpose of determining violations of traffic rules, but are also intended to have a preventive effect. To do this, devices for red light monitoring would have to be installed at a large number of traffic light controlled intersections in the city area. This would require considerable effort both for the installation of the devices and for the evaluation of the recordings made with them. For this reason, traffic monitoring devices are often designed in two parts: they contain permanently installed components and an insert that can be used at different locations. The permanently installed, stationary components are the sensor embedded in the road surface and a housing, which is usually arranged on a column, the sensor being connected to connections in the housing via permanently installed lines. The insert contains the photographic camera, a flash unit and a control and evaluation unit, which controls the functional sequence and links the signals received from the sensor and the traffic light for triggering or not triggering the camera. It can then be used in an irregular sequence in different locations in the respective housing. The driver then does not know in which housing an insert with camera, flash unit and control and evaluation unit is used, which system is therefore ready for operation.

An den verschiedenen Einsatzorten liegen häufig unterschiedliche Bedingungen vor, die im Funktionsablauf der Vorrichtung zur Verkehrsüberwachung berücksichtigt werden müssen: Es können beispielsweise den Sperrphasen "Rot" unterschiedlich lange "Gelbphasen" vorgeschaltet sein. Die räumlichen Abmessungen von Kreuzungen und die Lagen der Fühler zu den Kreuzungen können unterschiedlich sein, was für verschiedene Einsatzorte verschiedene Einstellungen von Verzögerungszeiten erforderlich macht. Es muß zur Registrierung auf oder mit den Aufnahmen eine Kennung oder Bezeichnung des Einsatzortes eingegeben werden. In vielen Fällen hat der Einsatzort auch noch spezielle Besonderheiten. Es kann beispielsweise zu bestimmten Zeiten der Sonnenstand so ungünstig sein, daß keine brauchbaren Aufnahmen gemacht werden können. Es wird dann notwendig, die Vorrichtung während dieser Zeiten auszuschalten, um einen unnötigen Filmverbrauch zu vermeiden. Zu diesem Zweck sind an bekannten Vorrichtungen zur Überwachung ampelgeregelter Kreuzungen Einstellmöglichkeiten vorgesehen, mittels welcher der Polizeibeamte die dem jeweiligen Einsatzort zugeordneten Parameter manuell eingibt.Different conditions are often present at the different locations, which must be taken into account in the functional sequence of the traffic monitoring device: for example, the blocking phases "red" can be preceded by "yellow phases" of different lengths. The spatial dimensions of intersections and the positions of the sensors to the intersections can be different, which requires different settings of delay times for different locations. For registration on or with the recordings, an identifier or designation of the place of use must be entered. In many cases, the place of use also has special features. For example, at certain times the position of the sun can be so unfavorable that no usable pictures can be taken. It then becomes necessary to turn the device off during these times to avoid unnecessary film consumption. For this purpose, setting options are provided on known devices for monitoring traffic light-controlled intersections, by means of which the police officer manually inputs the parameters assigned to the respective location of use.

Eine solche manuelle Eingabe ist umständlich. Sie erfordert besondere Aufmerksamkeit. Es besteht dadurch die Gefahr einer falschen Eingabe der Daten. Durch das Risiko einer falschen Eingabe von Daten wird die Beweiskraft der Aufnahme gemindert. Eine falsche Eingabe von Ausschaltzeiten führt zu unnötigem Filmverbrauch und vermindert die Betriebszeit, während welcher tatsächlich eine Überwachung stattfindet.Such manual entry is cumbersome. It requires special attention. There is a risk of incorrect data entry. The risk of incorrect data entry reduces the probative value of the recording. Incorrect entry of switch-off times leads to unnecessary film consumption and reduces the operating time during which monitoring actually takes place.

Es sind weiterhin mit Doppler - Radar arbeitende Geschwindigkeits - Überwachungsvorrichtungen bekannt. Bei diesen wird mittels einer Radarantenne ein Radarstrahl erzeugt. Aus der bei der Reflexion an einem bewegten Fahrzeug infolge des Dopplereffekts erhaltenen Frequenzverschiebung wird die Geschwindigkeit des Fahrzeugs bestimmt. Die so bestimmte Geschwindigkeit wird mit einer vorgegebenen Höchstgeschwindigkeit verglichen. Wenn diese Höchstgeschwindigkeit überschritten wird50z50z, wird eine Kamera ausgelöst und eine Aufnahme des Fahrzeugs gemacht, die eine Identifizierung des Fahrzeugs gestattet (CH-A 414 210).Speed monitoring devices operating with Doppler radar are also known. In these, a radar beam is generated by means of a radar antenna. The speed of the vehicle is determined from the frequency shift obtained when reflecting on a moving vehicle as a result of the Doppler effect. The speed determined in this way is compared with a predetermined maximum speed. When this top speed is exceeded If 50z50z, a camera is triggered and a picture of the vehicle is taken, which allows the vehicle to be identified (CH-A 414 210).

Auch solche Geschwindigkeits - Überwachungsvorrichtungen werden häufig "stationär" an ganz bestimmten Einsatzorten benutzt. Auch hier ist es bekannt, an diesen Einsatzorten, beispielsweise an Brückenkonstruktionen über Schnellstraßen, Gehäuse fest zu installieren und das eingentliche Meßgerät mit der Kamera und der Steuerung als Einsatz auszubilden, der wahlweise in verschiedene Gehäuse eingesetzt wird. Auch hier ist es erforderlich, an dem Gerät die dem jeweiligen Einsatzort zugeordneten Parameter einzustellen. Dazu gehört vor allem die an dem Einsatzort vorgegebene Höchstgeschwindigkeit.Such speed monitoring devices are also often used in a "stationary" manner at very specific locations. It is also known here to permanently install housings at these locations, for example on bridge constructions over expressways, and to design the actual measuring device with the camera and the controller as an insert, which is optionally used in different housings. Here, too, it is necessary to set the parameters assigned to the respective place of use on the device. Above all, this includes the maximum speed specified at the place of use.

Es sind auch als Einsatz ausgebildete Vorrichtungen mit einer Kamera und einer Steuer- und Auswerteeinheit bekannt, die wahlweise für die Überwachung ampelgesteuerter Kreuzungen und zur Geschwindigkeitsüberwachung in fest installierten Gehäusen einsetzbar sind. Es muß dann in die Steuer- und Auswerteeinheit ein der gewünschten Einsatzart zugeordnetes Programm eingegeben werden.Devices designed as an insert with a camera and a control and evaluation unit are also known, which can optionally be used for monitoring traffic light-controlled intersections and for speed monitoring in permanently installed housings. A program assigned to the desired type of application must then be entered in the control and evaluation unit.

Offenbarung der ErfindungDisclosure of the invention

Der Erfindung liegt die Aufgabe zugrunde, bei einer Vorrichtung zur Verkehrsüberwachung mit einem wahlweise in verschiedenen stationären Gehäusen verwendbaren Einsatz die Anpassung an die verschiedenen Einsatzorte zu vereinfachen und Einstellfehler zu vermeiden.The object of the invention is to simplify the adaptation to the different locations and to avoid setting errors in a device for traffic monitoring with an insert which can optionally be used in different stationary housings.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß

  • (c) die Vorrichtung gehäusefeste Datenspeichermitel enthält, in denen die für den Einsatzort spezifischen Daten gespeichert werden und dass sie so ausgestaltet ist, dass diese Daten beim Einsetzen des Einsatzes in das Gehäuse auf die Steuer- und Auswerteeinheit übertragbar sind.
According to the invention, this object is achieved in that
  • (c) the device contains housing-fixed data storage devices in which the data specific to the place of use are stored and that it is designed such that this data can be transferred to the control and evaluation unit when the insert is inserted into the housing.

Es braucht dann beim Wechsel des Einsatzes nichts eingestellt zu werden. Die Parameter sind in den gehäusefesten Datenspeichermitteln gespeichert. Von diesen "erfährt" der Einsatz die Kennung des Einsatzortes, Zeitverzögerungen oder Höchstgeschwindigkeitenoder lokalspezifische Ausschaltzeiten. Die Bedienung der Vorrichtung beim Wechsel des Einsatzes wird dadurch vereinfacht und beschleunigt. Fehleinstellungen werden ausgeschlossen.Then nothing needs to be set when changing the insert. The parameters are stored in the data storage means fixed to the housing. The operation "learns" from these the location identifier, time delays or maximum speeds or local specific switch-off times. The operation of the device when changing the insert is simplified and accelerated. Incorrect settings are excluded.

Die DE-A 3 422 764 beschreibt ein Aufzeichnungssystem für Bilder von Aufnahmeobjekten, z.B. Fahrzeugen, und diesen zugeordneten Daten. Durch zwei Lichtschranken wird die Geschwindigkeit des Fahrzeugs gemessen. Bei Überschreiten einer vorgegebenen Höchstgeschwindigkeit wird ein Auslösesignal erzeugt. Das Messobjekt (Fahrzeug) wird dann von einer Videokamera aufgenommen und zusammen mit zugehörigen Daten, wie Datum und Geschwindigkeit, in Form einer gemeinsamen elektronischen Bildinformation gespeichert. Diese Bildinformation wird auf ein und demselben Bildträger, nämlich einem Monitor oder einem Videodrucker dargestellt.DE-A 3 422 764 describes a recording system for images of objects, e.g. Vehicles, and associated data. The speed of the vehicle is measured by two light barriers. A trigger signal is generated when a predetermined maximum speed is exceeded. The measurement object (vehicle) is then recorded by a video camera and stored together with associated data, such as the date and speed, in the form of common electronic image information. This image information is displayed on one and the same image carrier, namely a monitor or a video printer.

Die US-A 4 173 010 zeigt Geschwingkeitsfühler, durch welche die Geschwindigkeit eines Fahrzeugs gemessen wird. Die Geschwindigkeit wird auf einer Anzeigetafel für den Fahrer dargestellt. Bei Überschreiten einer vorgegebenen Geschwindigkeit oder bei zu dichtem Auffahren wird das Fahrzeug von einer Filmkamera aufgenommen. Aus der Anzahl der Bilder kann auf die Geschwindigkeit des Fahrzeugs geschlossen werden.US-A 4 173 010 shows speed sensors by which the speed of a vehicle is measured. The speed is shown on a display board for the driver. The vehicle is recorded by a film camera if a predetermined speed is exceeded or if the drive-up is too close. The speed of the vehicle can be inferred from the number of images.

Die US-A 4 258 430 beschreibt eine Anordnung zum Sammeln und Speichern von Informationen, bei welchem die Informationen in einen elektronischen Speicher einschreibbar sind. Eine Speichereinheit mit diesem Speicher ist wahlweise aus der Anordnung entfernbar und kann in ein Datenverarbeitungszentrum eingesetzt werden.US-A 4 258 430 describes an arrangement for collecting and storing information, in which the information can be written into an electronic memory. A memory unit with this memory can optionally be removed from the arrangement and can be used in a data processing center.

Bevorzugte Ausführungen der ErfindungPreferred embodiments of the invention

Fig.1 ist eine schematisch - perspektivische Darstellung einer Kreuzung 10, die durch eine Ampel 12 geregelt ist. Die übrigen Ampeln der Kreuzung sind zur Vereinfachung der Darstellung nicht gezeigt. In der Fahrbahndecke einer in die Kreuzung einmündenden Straße 14 ist kurz vor der Einmündung in die Kreuzung 10 ein Fühler 16 in Form einer Induktionsschleife eingelassen. Der Fühler 16 spricht an, wenn ein Fahrzeug 18 darüberfährt.1 is a schematic perspective illustration of an intersection 10, which is regulated by a traffic light 12. The remaining traffic lights of the intersection are not shown to simplify the illustration. A sensor 16 in the form of an induction loop is embedded in the road surface of a road 14 leading into the intersection just before the intersection with the intersection 10. The sensor 16 responds when a vehicle 18 drives over it.

Eine Vorrichtung 18 zur photographischen Überwachung der Kreuzung 10 ist in einem Gehäuse 20 angeordnet, das auf einer Säule 22 in kurzem Abstand vor der Kreuzung 10 angeordnet ist. Die Vorrichtung 18 enthält eine Steuer- und Auswerteeinheit 24, eine von der Steuer- und Auswerteeinheit gesteuerte photographische Kamera 26 und ein Blitzlichtgerät 28. Die Steuer- und Auswerteeinheit 24 erhält ein Fühlersignal von dem Fühler 16 über eine Leitung 30 sowie ein Sperrphasensignal von der Ampel 12 über eine Leitung 32, wenn die Ampel auf Sperrphase umschaltet.A device 18 for photographic monitoring of the intersection 10 is arranged in a housing 20 which is arranged on a column 22 at a short distance from the intersection 10. The before Direction 18 contains a control and evaluation unit 24, a photographic camera 26 controlled by the control and evaluation unit and a flash unit 28. The control and evaluation unit 24 receives a sensor signal from the sensor 16 via a line 30 and a blocking phase signal from the traffic light 12 via a line 32 when the traffic light switches to the blocking phase.

Wie aus Fig.2 ersichtlich ist, sind die Kamera 26, das Blitzlichtgerät und die Steuer- und Auswerteeinheit in einem gehäuseartigen Einsatz 34 montiert. Der Einsatz 34 ist aus dem Gehäuse 20 mittels zweier Handgriffe 36 wahlweise herausziehbar und wiedereinsetzbar. Die Rückwand 38 des Gehäuses 20 kann zu diesem Zweck wie eine Tür aufgeklappt werden. Es ist also möglich, mit einem solchen Einsatz 34 mehrere stationär angebrachte Gehäuse wahlweise, also nach Bedarf oder in unregelmäßigem Turnus, zubestücken.As can be seen from FIG. 2, the camera 26, the flash unit and the control and evaluation unit are mounted in a housing-like insert 34. The insert 34 can be pulled out and reinserted from the housing 20 by means of two handles 36. For this purpose, the rear wall 38 of the housing 20 can be opened like a door. It is therefore possible, with such an insert 34, to equip a plurality of stationary housings optionally, that is to say as required or at irregular intervals.

In Fig.3 ist die Vorrichtung in einem Blockdiagramm dargestellt. Mit 12 ist wieder die Ampel bezeichnet, und mit 16 ist der in der Straßendecke verlegte Fühler bezeichnet. Die Ampel 12 liefert während der Sperrphase ein Signal. Das ist durch Block 41 dargestellt. Die Signale von dem Fühler 16 und von der Ampel 12 können durch einstellbare Zeitglieder 42 bzw.44 um Zeiten Ti bzw. T2 verzögert werden. Dadurch können Unterschiede zwischen den verschiedenen Einsatzorten hinsichtlich der Position des Fühlers 16 und der Dauer der Gelbphase, zugelassene Toleranzen o.dgl. berücksichtigt werden. Die Verzögerten Signale beaufschlagen eine Signalauswerteschaltung 46, die praktisch einem UND - Glied entspricht . Feinheiten der Schaltung sind der Einfachheit der Darstellung halber weggelassen. Die Signalauswerteschaltung 46 steuert einen Kameraauslöser 48. Der Kameraauslöser erhält ein Auslösesignal, wenn während der Sperrphase ein Fühlersignal von dem Fühler 16 erzeugt wird. Durch den Kameraauslöser 48 wird die Kamera 26 ausgelöst.The device is shown in a block diagram in FIG. The traffic light is again designated with 12 and the sensor installed in the road surface is designated with 16. The traffic light 12 delivers a signal during the blocking phase. This is represented by block 41. The signals from the sensor 16 and from the traffic light 12 can be delayed by times Ti and T 2 by adjustable timers 42 and 44, respectively. As a result, differences between the various locations with regard to the position of the sensor 16 and the duration of the yellow phase, permitted tolerances or the like. be taken into account. The delayed signals act on a signal evaluation circuit 46, which practically corresponds to an AND gate. Subtleties of the circuit are omitted for simplicity of illustration. The signal evaluation circuit 46 controls a camera trigger 48. The camera trigger receives a trigger signal if a sensor signal is generated by the sensor 16 during the blocking phase. The camera 26 is triggered by the camera trigger 48.

Es wird dann eine Aufnahme gemacht, welche die Kreuzung mit der auf Sperrphase stehenden Ampel und dem in die Kreuzung einfahrenden Fahrzeug 40 zeigt. Weiterhin werden in die Aufnahme Anzeigen eines Einsatzortanzeigers 50, einer Uhr 52 und eines Datumanzeigers 54 eingespiegelt.A picture is then taken which shows the intersection with the traffic light which is in the blocking phase and the vehicle 40 entering the intersection. Furthermore, displays of a location indicator 50, a clock 52 and a date indicator 54 are reflected in the recording.

Eine Zeitsteuerung 56, die von der Uhr 52 getaktet wird, kann die Auslösung der Kamera 26 in bestimmten Zeitintervallen von t1 bis t2 verhindern. Das ist durch einen Schalter 58 zwischen der Signalauswerteschaltung 46 und dem Kameraauslöser 48 symbolisiert. Der Schalter 58 ist von der Zeitsteuerung 56 während dieser Zeitintervalle geöffnet. Die Zeitintervalle, während welche keine Aufnahmen gemacht werden sollen, sind abhängig vom Einsatzort. Sie können beispielsweise dadurch bedingt sein, daß während dieser Zeit die Sonne in das Objektiv der Kamera 26 strahlt, so daß keine brauchbaren Aufnahmen gemacht werden können.A time control 56, which is clocked by the clock 52, can prevent the triggering of the camera 26 at certain time intervals from t 1 to t 2 . This is symbolized by a switch 58 between the signal evaluation circuit 46 and the camera trigger 48. The switch 58 is opened by the time controller 56 during these time intervals. The time intervals during which no pictures are to be taken depend on the location. They can be caused, for example, by the fact that the sun shines into the lens of the camera 26 during this time, so that no usable pictures can be taken.

Die Parameter Ti und T2 sowie das Zeitintervall t1 bis t2 und eventuelle weitere vom Einsatzort abhängige Parameter sind in gehäusefest im Gehäuse 20 angebrachten Datenspeichermitteln 60 in Form eines Halbleiter - Datenspeichers gespeichert. Diese Datenspeichermittel 60 übertragen die Parameter auf die Steuer- und Auswertereinheit 24. Das ist in Fig.3 durch Leitungen 62, 64 und 66 angedeutet.The parameters Ti and T 2 as well as the time interval t 1 to t 2 and any further parameters which depend on the place of use are stored in the form of a semiconductor data memory in data storage means 60 fixed in the housing 20. These data storage means 60 transmit the parameters to the control and evaluation unit 24. This is indicated in FIG. 3 by lines 62, 64 and 66.

Ebenso werden von den Datenspeichermitteln 60 Informationen über den Einsatzort an den Einsatzortanzeiger 50 übermittelt. Die Vorrichtung wird also beim Einsetzen des Einsatzes 34 in das Gehäuse 20 automatisch auf die richtigen Parameter des Einsatzortes eingestellt und auch die Kennung des Einsatzortes automatisch in den Einsatzortanzeiger 50 eingegeben. Einer Einstellung durch den Benutzer bei jedem Umsetzen bedarf es nicht. Die Daten brauchen vielmehr nur einmal in die gehäusefesten und dem Gehäuse 20 zugeordneten Datenspeichermittel 66 eingegeben zu werden.Likewise, information about the place of use is transmitted from the data storage means 60 to the place of use indicator 50. The device is thus automatically set to the correct parameters of the place of use when inserting the insert 34 into the housing 20, and the identifier of the place of use is also automatically entered into the place of use indicator 50. A setting by the user with each implementation is not required. Rather, the data need only be entered once into the data storage means 66 fixed to the housing and assigned to the housing 20.

Fig.4 zeigt einen als Datenspeichermittel 60 verwendbaren Halbleiter - Datenträger in Form eines kartenförmigen integrierten Schaltkreises 68 (Memory Card) mit einer Kontaktleiste 70. Memory Cards sind an sich bekannt und handelsüblich erhältlich ("Elektronik" 19(1986),100-101).4 shows a semiconductor data carrier that can be used as data storage means 60 in the form of a card-shaped integrated circuit 68 (memory card) with a contact strip 70. Memory cards are known per se and are commercially available ("Elektronik" 19 (1986), 100-101) .

Es können aber auch andere Datenspeichermittel benutzt werden. In manchen Fällen können die Datenspeichermittel von einem codierten Stecker oder einer codierten Steckerbuchse gebildet sein; die an dem Gehäuse 20 angebracht sind und beim Einschieben des Einsatzes mit einem komplementären Gegenstück des Einsatzes 34 Kontakt geben.However, other data storage means can also be used. In some cases, the data storage means can be formed by a coded plug or a coded plug socket; which are attached to the housing 20 and, when the insert is inserted, make contact with a complementary counterpart of the insert 34.

Fig.5 zeigt eine Vorrichtung zur Verkehrsüberwachung, bei welcher mittels eines Doppler - Radars die Geschwindigkeit von Fahrzeugen überwacht wird.5 shows a device for traffic monitoring, in which the speed of vehicles is monitored by means of a Doppler radar.

Die Vorrichtung 72 ist seitlichvon einer Straße 74 angeordnet. Mit 76 ist einzu überwachendes Fahrzeug bezeichnet. Die Vorrichtung 72 enthält eine Radarantenne 78, die eine "Radarkeule" 80 aussendet. Die "Radarkeule" stellt die ausgesandte Strahlungsenergie pro Raumwinkel in Abhängigkeit vom Winkel dar.Weiterhin enthält die Vorrichtung 72 eine photographische Kamera 82, die ein Gesichtsfeld 84 erfaßt. Die Signale der Radarantenne 78 sind auf eine Meß- und Auswerteschaltung 86 geschaltet.Die Meß- und Auswerteschaltung 86 liefert einen Meßwert für die Geschwindigkeit des überwachten Fahrzeugs 76, wenn das Fahrzeug 76 durch die Radarkeule 80 hindurchgefahren ist. Bei Überschreiten einer zulässigen Höchstgeschwindigkeit wird die Kamera 82 ausgelöst. Die Auslösung erfolgt dabei in einem Zeitpunkt, in welchem sich das Fahrzeug 76 im wesentlichen in der Mitte des Gesichtsfeldes 84 der Kamera 82 befindet.The device 72 is located to the side of a street 74. A vehicle to be monitored is designated by 76. The device 72 contains a radar antenna 78 which transmits a "radar lobe" 80. The "radar lobe" represents the emitted radiation energy per solid angle as a function of the angle. Furthermore, the device 72 contains a photographic camera 82 which detects a field of view 84. The signals from the radar antenna 78 are connected to a measuring and evaluation circuit 86. The measuring and evaluation circuit 86 provides a measured value for the speed of the monitored vehicle 76 when the vehicle 76 has passed through the radar lobe 80. When a permissible maximum speed is exceeded, the camera 82 is triggered. It is triggered at a point in time at which the vehicle 76 is essentially in the middle of the field of view 84 of the camera 82.

Die Kamera 82 und die Meß- und Auswerteschaltung 86 sitzen zusammen mit Anzeigegeräten in einem Einsatz 88. Der Einsatz 88 ist wiederum herausnehmbar in einem stationären Gehäuse 90 angeordnet. In dem Gehäuse 90 sitzt ein Halbleiter - Datenspeicher 92 oder eine codierte Steckerbuchse. Beim Einsetzen des Einsatzes 86 in das Gehäuse 90 überträgt der Halbleiter - Datenspeicher auf die Meß- und Auswerteschaltung 86 Parameter für den Betrieb der Vorrichtung an dem speziellen Einsatzort. Insbesondere liefert der Datenspeicher die an dem Einsatzort zu überwachende Höchstgeschwindigkeit.The camera 82 and the measurement and evaluation circuit 86 sit together with display devices in an insert 88. The insert 88 is in turn removably arranged in a stationary housing 90. A semiconductor data memory 92 or a coded plug socket is located in the housing 90. When the insert 86 is inserted into the housing 90, the semiconductor data memory transmits to the measuring and evaluation circuit 86 parameters for the operation of the device at the specific place of use. In particular, the data storage device delivers the maximum speed to be monitored at the place of use.

In Fig.6 ist Aufbau und Funktion der Vorrichtung rein schematisch in einem Blockdiagramm dargestellt. In einem Einsatz 88 sind die Kamera 82, die Meß- und Auswerteschaltung 86, eine Einsatzortanzeige 94, eine Uhr 96 und eine Datumanzeige 98 angeordnet. Die Meß- und Auswerteschaltung 86 enthält eine Signalverarbeitungsschaltung 100, die aus den Radarsignalen einen Meßwert für die Geschwindigkeit des Fahrzeuges 76 bildet. Dieser Meßwert wird durch eine Anzeigevorrichtung 102 angezeigt. Außerdem wird er durch einen Vergleicher 104 mit einer vorgegebenen Höchstgeschwindigkeit verglichen. Wenn der Meßwert höher als die Höchstgeschwindigkeit ist, wird ein Auslösesignal auf einen Auslöser 106 gegeben und die Kamera 82 ausgelöst. Die Kamera 82 macht eine Aufnahme des überwachten Fahrzeugs 76, der Geschwindigkeitsanzeige an der Anzeigevorrichtung 102 sowie der Einsatzortanzeige, der Uhrzeit und des Datums.The structure and function of the device is shown purely schematically in a block diagram in FIG. The camera 82, the measurement and evaluation circuit 86, a location indicator 94, a clock 96 and a date display 98 are arranged in an insert 88. The measuring and evaluation circuit 86 contains a signal processing circuit 100 which forms a measured value for the speed of the vehicle 76 from the radar signals. This measured value is displayed by a display device 102. It is also compared by a comparator 104 at a predetermined maximum speed. If the measured value is higher than the maximum speed, a trigger signal is sent to a trigger 106 and the camera 82 is triggered. The camera 82 takes a picture of the monitored vehicle 76, the speed display on the display device 102 and the location display, the time and the date.

Durch die Datenspeichermittel wird der Einsatzort über Datenleitung 108 auf die Einsatzortanzeige 94 übertragen. Über Leitung 110 wird dem Vergleicher 104 die am Einsatzort geltende zulässige Höchstgeschwindigkeit vorgegeben.The place of use is transmitted to the place of use display 94 via data line 108 by the data storage means. The permissible maximum speed applicable at the place of use is specified to the comparator 104 via line 110.

Es kann auch ein einziger Einsatz wahlweise sowohl für die Geschwindigkeitsüberwachung als auch für die im Zusammenhang mit Fig.1 beschriebene Überwachung einer ampelgeregelten Kreuzung benutzt werden. Die Funktionen unterscheiden sich nur durch die Signalverarbeitung. In diesem Fall wird über Leitung 112 von den Datenspeichermitteln das Programm für die Geschwindigkeitsüberwachung aufgerufen.A single insert can also be used either for speed monitoring or for monitoring a traffic light-controlled intersection as described in connection with FIG. The functions differ only in the signal processing. In this case, the program for the speed monitoring is called up via line 112 from the data storage means.
