Definitions

  • the present invention relates to a monitoring system of road traffic in order to identify violations of the rules, such as driving too fast, driving on with red traffic light, insufficient safety distance and / or the like, with at least one object sensor Objects monitored and depending on their sensory recorded movements or positions output signals as Actual values are generated in a with the object sensor connected evaluation device processed and with predetermined Target or limit values are compared, and where in the case of a deviation of the actual value from the respective predetermined target or limit value Rule violation a trigger signal is generated, which a Acquisition of an image of the respective object using a camera together with data about the respective rule violation causes, in the event of a detected violation the captured image together with the associated one Data as electrical data signals over a data connection to one of the object sensor and the evaluation device remote acquisition station for storage and / or further evaluation is transmitted.
  • violations of the rules such as driving too fast, driving on with red traffic light, insufficient safety distance and / or the like
  • Laser guns For speed measurement, stationary and mobile radar devices or mobile laser measuring devices, so-called Laser guns known. With the last mentioned laser devices is a disadvantage that due to the highly bundled Laser beam the device manually the moving object must be tracked. The device usually has to do this be held directly in front of the eye, it turns out has that this is the health of the eye of the Operator, but also the occupant (s) of each measured vehicle. Further is known for measuring speed or for checking stopping e.g. Induction loops in front of red traffic lights to be used in the carriageway or light barriers.
  • the known systems therefore work with different types Measuring devices and either without Image acquisition, whereby due to the necessary immediate Stopping the respective road user high personnel expenses in order to determine the personal details is required, or with a photochemical Image capture (photography), which also becomes a very high effort and costs for maintenance and administration leads. So the footage has to be at certain intervals changed manually, time-consuming transport and processed and finally also manually for and holder detection can be evaluated. Everything this and also the subsequent sending of fines requires extremely high personnel and administrative burden. There is also an extremely high failure rate; for example, by early consumption of the Subsequent rule violations can no longer be used for film material be recorded. After all, the known systems are too highly vulnerable to sabotage or vandalism Destruction or theft of footage previously "traffic offender" caught a fine or one could evade law enforcement.
  • Object sensor detection means in the form of two detectors arranged in slots in the roadway (obviously provided in the manner of induction loops), while according to DE-A-34 22 764 a measuring arrangement with two Light barriers running across the road are provided should be.
  • Street-related sensor elements mainly for speed detection.
  • light barriers are natural very easy to manipulate and are subject to a very high Risk of sabotage because their function is very easy e.g. by objects placed to interrupt the light beam can be disturbed.
  • Induction wires or loops must be embedded in the pavement, which represents quite a lot of assembly work.
  • an "object (screen) Monitoring system” (monotoring system) known. Objects should be through permanent image acquisition (video surveillance) be monitored. There is an object detection using a variety of cameras (detection cameras) provided with which a constant image acquisition (monitoring) of the respective objects on their journey over one certain traffic route. Based on this constantly monitored images will determine if it is the respective vehicle by a certain vehicle type, e.g. a truck, trades, and then maybe one more special picture (practically as a still picture) by means of a additional camera (image acquisition camera) can be captured. In any case, however, the means of detection cameras constantly captured images to a control station transmits, not just those on special occasions captured (still) images of the acquisition cameras.
  • the present invention is based on the object universal for different monitoring situations to create applicable traffic monitoring system with the time and manpower required for the operation and the maintenance as well as the risk of sabotage to a minimum reduced and thereby also the detection security can be increased significantly.
  • the object sensor is designed as a laser sensor with one in the direction of the object optically expanded laser beam emitted is working.
  • a protective housing for example in the form of a so-called "starter box” so that it is relatively well protected from acts of sabotage can be.
  • the system according to the invention is in familiar way - a practically unattended, automatic monitoring system, which increases personnel and administrative expenses significantly reduced. That's the way it is especially unnecessary to replace film material and to process photochemically, since the pictures together with the additional data electronically transmitted and evaluated become.
  • the immediate transmission of the data also eliminates the risk of images being used as evidence can be destroyed or stolen because the Destruction of the camera cannot destroy the image since this already together with the additional information in the form of electrical, especially digital signals transferred and especially on CD-ROM for documentation has been saved. It is advantageous that practical hardly the possibility of an unauthorized intervention in the central acquisition station.
  • the vehicle registration number can then use suitable image processing software are automatically recognized and it can over a suitable network of computers Vehicle owners can be determined. It is also advantageous possible, via a saved fine table also set the respective fine as well as automatically print out and send the fine. Possibly automatic monitoring then also takes place of the incoming payments from the fine notices possibly sending reminders or similar follow-up measures.
  • a traffic monitoring system exists as essential “main components” from at least one external, i.e. at the location of the desired traffic monitoring to be arranged monitoring station 2 and one removed lying ("central") detection station 4, wherein the monitoring station 2 with the detection station 4 over a data link 6 is connected to a wired (electrical conductor / light conductor) or wireless (public) data network belongs, in particular to the ISDN network 8 of DeutscheInstitut or to a radio network or digital radio telephone network 10 (see Fig. 3).
  • the ISDN network 8 of DeutscheInstitut or to a radio network or digital radio telephone network 10 (see Fig. 3).
  • external monitoring stations 2 are provided, which are then determined in each case Locations or "traffic hotspots" arranged and each via a data connection 6 with the "central" detection station 4 can be connected.
  • Each monitoring station 2 is expediently basically similar and in particular "modular" structure; she consists at least of a sensor module 12, an evaluation or computer module 14, preferably a camera module 16 Flash device module 18, in particular a buffer module 20 and a data interface module 22.
  • the sensor module 12 has an object sensor 24, which is designed according to the invention as a laser distance sensor, the - to make a stationary arrangement possible - with an optically widened laser beam 26 operates, which is a tracking of the beam with respect to the moving objects 28 (especially motor vehicles) makes redundant.
  • the evaluation or computer module 14 forms the essential Part of an evaluation device 30 that measures the measured values of the object sensor 24 by means of suitable computer operations evaluates whether a rule violation of the respective object 28 is present or not.
  • the camera module 16 has a camera 32, in which it preferably a digital (electronic) still camera (e.g. so-called "CCD camera").
  • a digital (electronic) still camera e.g. so-called "CCD camera”
  • road traffic is ongoing or but only during certain ones, for example by a random number generator fixed times by the object sensor 24 monitors.
  • the captured image is together with the associated one Data via the data link 6 to the central acquisition station 4 for storage and / or further arithmetic evaluation transferred.
  • the transfer was made is preferably from the detection station 4 to the each monitoring station 2 reported back; if there is no response, there is an automatic retransmission or repeated transmission until the correct Feedback received.
  • the image and Additional data temporarily stored in the intermediate storage module 20, the data at the earliest after transmission confirmation to be deleted.
  • the electrical Images and data then transmitted data signals evaluated mathematically in practically any way become. So it is particularly possible to have an automatic To cause license plate recognition and holder identification, why the detection station 4 expediently with further data memories 34, for example from vehicle registration offices is networked, and preferably also over data connections 6. Furthermore, an automatic Determination of fines and an automatic submission of fines.
  • the system according to the invention can advantageously also with self-monitoring especially of the external monitoring stations 2 equipped against sabotage and vandalism be.
  • the or each external monitoring station can do this 2 at least one additional movement and / or have a touch detector in the event of an approach and / or manipulation by an unauthorized person Person causes an alarm and in particular an alarm transmission via the data connection 6 and / or a detection and transmission of an image of the unauthorized person.
  • This is Mutual image capture is possible, including unauthorized ones To be able to visually capture people who are the other, opposite monitoring station approach for unfair purposes.
  • an object 28 can be "photographed" from the front and back.
  • the system according to the invention can advantageously also used regardless of established rule violations be used, for example, to carry out searches after, for example, stolen vehicles.
  • the determined License plate automatically with a saved license plate list (Wanted list) are compared and in the case a determined reporting function a certain reporting function is triggered. With this reporting function it can is an alarm, preferably together with the license plate directly to a specified number, for example a police station.
