Definitions

  • the present invention relates to a system for monitoring road traffic for the purpose of determining violations of the rules, such as driving too fast, driving on when the traffic light is red, the safety distance is too short and / or the like, objects being monitored with at least one object sensor and depending on their sensor-detected movements or Positions output signals are generated as actual values, which are processed in an evaluation device connected to the object sensor and compared with predetermined target or limit values, and a trigger signal is generated in the event of a control violation determined as a deviation of the actual value from the respective predetermined target or limit value , which causes an image of the respective object to be captured by means of a camera together with data about the respective rule violation.
  • violations of the rules such as driving too fast, driving on when the traffic light is red, the safety distance is too short and / or the like
  • objects being monitored with at least one object sensor and depending on their sensor-detected movements or Positions output signals are generated as actual values, which are processed in an evaluation device connected to the object sensor and compared with predetermined target or limit values,
  • laser guns In known traffic monitoring systems, stationary and mobile radar devices or mobile laser measuring devices, so-called laser guns, are primarily used for speed measurement. With the last mentioned laser devices is disadvantageous that due to the highly focused laser beam, the device must be manually tracked the moving object. For this purpose, the device usually has to be held directly in front of the eye, and it has been found that this can endanger the health of the eye of the operator, but also of the occupant (s) of the respective measured vehicle. It is also known to use induction loops in the carriageway or light barriers to measure speed or to check stopping, for example in front of red light signal systems.
  • the known systems consequently work with different types of measuring devices and either without image acquisition, whereby due to the immediate stopping of the respective road user, which is necessary to determine the personal details, a high expenditure of personnel is required, or with a photochemical image acquisition (photography), which also results in a very high level Effort and high costs for maintenance and administration leads.
  • the film material has to be changed manually at certain intervals, transported and processed in a time-consuming manner and finally also evaluated manually to determine the number plate and holder. All of this and also the subsequent sending of administrative fines requires an extraordinarily high amount of personnel and administration. There is also an extremely high failure rate; For example, due to premature consumption of the film material, subsequent rule violations can no longer be detected.
  • the known systems are also at high risk of sabotage or vandalism, whereby destruction or theft of the film material could prevent a previously recorded “traffic offender” from being fined or prosecuted.
  • the present invention has for its object to provide a traffic monitoring system that can be used universally for various types of monitoring situations, with which the time and manpower required for operation and maintenance as well as the risk of sabotage are reduced to a minimum and the detection security can be increased considerably.
  • this is achieved in that, in the event of a violation of the rule, the captured image, together with the associated data, is transmitted as electrical data signals via a data connection to a detection station located away from the object sensor and the evaluation device for the purpose of storage and / or further evaluation.
  • the image and the associated additional data are expediently transmitted immediately after the respective violation of the rules has been recorded, and preferably after the intermediate storage has been carried out in the evaluation device, with the preferably provided intermediate storage providing the possibility of repeated transmission of the image and additional data in the event of a transmission difficulty.
  • the invention thus creates a practically unattended, automatic monitoring system, which significantly reduces the personnel and administrative effort. It is therefore particularly superfluous to replace film material and process it photochemically, since the images are transmitted and evaluated electronically together with the additional data.
  • the immediate transmission of the data also eliminates the risk that images as evidence can be destroyed or stolen, because the destruction of the camera cannot destroy the image, since this, together with the additional information, has already been transmitted in the form of electrical, in particular digital, signals and in particular has been stored on CD-ROM for the purpose of documentation.
  • the advantage here is that there is practically no possibility of an unauthorized intervention in the central detection station.
  • the actual object sensor can in particular in all cases be designed as a distance sensor, preferably a laser sensor, which works according to the transit time method. Stopping or driving through, the speed, the (safety) distance and also the number of vehicles can be determined via the preferably digital evaluation of its time-dependent distance signals.
  • the stopping is determined via the temporal constancy of the time-dependent distance signal, the speed is determined via the time derivative of the distance signal, and the distance between two vehicles is determined by the time difference between two equal levels of the time-dependent distance signal.
  • the distance between two vehicles can e.g. can also be determined in meters using the speed.
  • the number of vehicles, i.e. the respective traffic volume is determined by counting the measurement events or changes in distance.
  • a digital image in particular is automatically recorded, which is then transmitted via an interface is read into a computer module of the evaluation device and there is provided with the case-specific additional information about time, location, speed, distance, etc.
  • the signals can then be compressed, buffered and automatically transmitted to the central recording station via the data connection, in particular via the DeutscheInstitut ISDN network.
  • the vehicle registration number can then be automatically recognized by means of suitable image processing software, and the vehicle owner can then also be automatically determined by means of a suitable computer network.
  • a traffic monitoring system consists as essential "main components" of at least one external monitoring station 2, ie to be arranged at the location of the desired traffic monitoring, and a remote ("central") detection station 4, the monitoring station 2 being connected to the detection station 4 via a data connection 6 , which belongs to a wired (electrical conductor / optical fiber) or wireless (public) data network, in particular to the ISDN network 8 of DeutscheInstitut or to a radio network or digital radio telephone network 10 (see FIG. 3).
  • a large number of external monitoring stations 2 will be provided, each of which is then determined at a specific one Locations or "traffic hotspots" arranged and each connected to the "central" detection station 4 via a data link 6.
  • Each monitoring station 2 is expediently basically of the same type and in particular of a “modular” design; it consists at least of a sensor module 12, an evaluation or computer module 14, a camera module 16 preferably with a 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 preferably a laser Distance sensor is designed which - in order to make a stationary arrangement possible - advantageously works with an optically widened laser beam 26, which makes tracking the beam with respect to the moving objects 28 (in particular motor vehicles) superfluous.
  • the evaluation or computer module 14 forms the essential part of an evaluation device 30, which evaluates the measured values of the object sensor 24 by suitable computer operations to determine whether there is a rule violation of the respective object 28 or not.
  • the camera module 16 has a camera 32, which is preferably a digital (electronic) single-image camera (e.g. a so-called "CCD camera").
  • a digital (electronic) single-image camera e.g. a so-called "CCD camera”
  • road traffic is now monitored continuously or only during certain times, for example determined by a random generator, by the object sensor 24.
  • the arithmetic evaluation by the evaluation device 30 reveals that a violation of certain traffic rules (Road traffic regulations), a trigger signal is generated which causes the acquisition of an image of the respective object by means of the camera 32 together with data about the respective violation of the rules.
  • the captured image is now transmitted together with the associated data via the data link 6 to the central capture station 4 for the purpose of storage and / or further computational evaluation.
  • the transmission that has taken place is preferably reported back from the detection station 4 to the monitoring station 2 that is transmitting; if there is no response, the data is automatically retransmitted or repeated until the correct response is received.
  • the image and additional data are temporarily stored in the buffer module 20, the data being deleted at the earliest after the transmission feedback has been given.
  • the images and data transmitted as electrical data signals can then be evaluated by calculation in virtually any manner. It is thus possible, in particular, to have an automatic license plate recognition and holder determination, for which purpose the registration station 4 is expediently networked with further data memories 34, for example from vehicle registration offices, and preferably also via data connections 6. Furthermore, an automatic determination of Fines as well as automatic sending of notices of fines.
  • the object sensor can in principle also optionally be designed as a microwave sensor, radio wave sensor, light sensor, ultrasonic sensor or the like.
  • Object sensor 24 can also be used in each case at least two position sensors, such as light barriers, induction loops, capacitive or resistive sensors, to be arranged at a predetermined distance when viewed in the direction of movement of the object.
  • the system according to the invention can advantageously also be equipped with self-monitoring, in particular of the external monitoring stations 2, against sabotage and vandalism.
  • the or each external monitoring station 2 can have at least one additional motion and / or touch detector which, in the event of an approach and / or manipulation by an unauthorized person, triggers 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.
  • Mutual monitoring of the monitoring stations 2 is thus realized by two cameras 32 in each case, wherein an object 28 can also be “photographed” from the front and rear at the same time.
  • the system according to the invention can advantageously also be used independently of established violations of the rule, for example to carry out searches for stolen vehicles, for example.
  • This reporting function can be an alarm, which is preferably transmitted together with the license plate directly to a predetermined number, for example a police station.
  • the license plate list stored in the monitoring station 2 can advantageously be updated via the data connection 6.
  • the sensor-acquired data are evaluated, in particular with regard to the respective speeds, safety distances and / or the respective traffic volume, in addition also for controlling automatic (electronic) traffic signs or warning signs or the like. This makes it possible, for example, to alert road users early on to sources of danger, such as traffic jams.
  • the monitoring system can also be equipped with additional air quality sensors, in particular pollutant sensors, the output variable of which is preferably also evaluated to control automatic traffic signs or warning signs or the like. Messages to the appropriate authorities and / or media (traffic radio) can also be triggered automatically if impermissibly high concentrations of pollutants are detected.
  • additional air quality sensors in particular pollutant sensors, the output variable of which is preferably also evaluated to control automatic traffic signs or warning signs or the like. Messages to the appropriate authorities and / or media (traffic radio) can also be triggered automatically if impermissibly high concentrations of pollutants are detected.
  • the monitoring stations 2 can advantageously be very easily integrated into light signal systems (traffic lights) and / or traffic signs or can be installed as additional devices.
  • Each monitoring station 2 is basically portable, so that a simple exchange is possible in the event of any malfunctions.
  • the system according to the invention is used to monitor stopping or driving through during the red phase of a light signal system, it can advantageously be "switched” to speed monitoring during the green and yellow phases.
  • the invention is not limited to the exemplary embodiments shown and described, but also encompasses all embodiments having the same effect in the sense of the invention. Furthermore, the invention has not yet been limited to the combination of features defined in claim 1, but can also be defined by any other combination of specific features of all the individual features disclosed in total.
