Definitions

  • the invention relates to a tunnel monitoring system in a vehicle tunnel according to the preamble of claim 1.
  • Tunnel monitoring systems in vehicle tunnels are different Commonly known embodiments:
  • a tunnel monitoring system in which in the tunnel and fire detectors are installed along the length of the tunnel.
  • This System should be a possible fire in the tunnel, especially a burning one Vehicle can be determined and localized.
  • This system can also Control device, which automatically in the event of a detected fire Warning devices, traffic control devices or shut-off devices actuated.
  • Such a monitoring system is only for detection suitable for fire-related hazards.
  • Another well-known tunnel monitoring system is made up of several Surveillance cameras, which are installed at a distance in the course of the tunnel are built. This allows assigned tunnel sections be visually monitored by the events captured by a camera Screens shown in a tunnel monitoring control center and from one Supervisor can be evaluated. Such surveillance cameras are also known swivel mount, with a remote controlled Swiveling from the tunnel monitoring control center is possible.
  • Such a tunnel monitoring system with surveillance cameras is costly to buy and maintain. In particular, they are Camera lenses in case of dirt and smoke critical fire is restricted in its function.
  • a protective function depends essentially on the individual attention of a surveillance person from time to time quick detection of a dangerous situation with required quick reactions is not guaranteed.
  • the object of the invention is to provide a tunnel monitoring system to provide that with good function inexpensive to manufacture and low maintenance is operable as well as extensive and variable monitoring information provides with the possibility of an automatic evaluation.
  • the localization sensors are ultrasonic sensors executed, each with a radiation and reception area on the least a lane are directed such that when a Vehicle in the radiation and reception area of an ultrasonic sensor from a corresponding sensor signal together with a sensor detection signal can be delivered to the evaluation unit.
  • the evaluation unit includes a transit time measuring unit with which by means of a sensor signal the stay of a vehicle in a radiation and reception area of a a runtime measurement can be activated for certain ultrasonic sensors. through a subsequent sensor signal one in the direction of travel in the tunnel following ultrasonic sensor, in its radiation and reception area the moving vehicle stays later is the travel time between at least these two ultrasonic sensors can be detected.
  • For the runtime measurement can use ultrasound sensors immediately following one another for evaluation or even more distant ultrasonic sensors can be used. There the distances of the ultrasonic sensors used for the transit time measurement are predefined and known, can be in a downstream speed measuring unit, which essentially consists of a multiplier immediately determines a speed signal for a specific vehicle become.
  • Speed measurements are preferably given in the above Type carried out for all vehicles entering the tunnel, whereby a runtime measurement when driving through a vehicle first ultrasonic sensor started and after driving through the second assigned ultrasonic sensor is terminated.
  • the Measuring section for a following vehicle and for a new runtime measurement can be reactivated.
  • Such measurement sections can be made in the course of the tunnel be set up one after the other so that practically every vehicle can be determined at each tunnel location. Derived from this can be easily and quickly Information such as average speeds driven or vehicle densities can be determined.
  • This arrangement can advantageously be particularly slow in a simple manner moving or stationary vehicle determined very quickly and automatically are assigned by a threshold for the runtime between two Ultrasonic sensors is set in the evaluation unit. With additional Evaluation of a sensor detection signal assigned to the current ultrasonic sensor can thus automatically the location of a broken down or particularly slow-moving vehicle can be detected in the tunnel. Also a determined sensor signal that is present during a specified time If not changed, the evaluation unit indicates that something has been left behind Vehicle.
  • the radiation and reception areas along the length of the tunnel successive ultrasonic sensors on the vehicle detection areas adjoin each other and in the longitudinal direction in the direction of vehicle travel correspond to the usual vehicle lengths. This will make one complete detection and monitoring of a lane over the entire length of the tunnel possible. In addition, a certain ultrasonic sensor only one vehicle can be detected, so that double detections or omissions of vehicles practically impossible are. This makes the evaluation result particularly reliable and meaningful.
  • a tunnel monitoring system is from relative affordable and reliable components.
  • ultrasonic sensors relatively inexpensive, reliable and low maintenance Encoder units operating in harsh operating conditions, for example are also proven in maritime use.
  • Such ultrasonic sensors are advantageous largely insensitive to contamination and also deliver usable signals for localization in the event of fire during smoke development of vehicles.
  • the evaluation of the sensor signals is together with the respective sensor detection signals relatively easily possible.
  • the installation cost and operating costs are also relatively low.
  • the exact vehicle passes using each individual vehicle a tracking unit possible.
  • a vehicle enters the tunnel detected by a first ultrasonic sensor and the vehicle passage through the following ultrasonic sensors to the tunnel exit a forwarding and handover circuit recorded and controlled.
  • a tracking unit can determine a broken down vehicle be when there is a break in the transmission of an ultrasonic sensor area to the next ultrasonic sensor area from the evaluation unit is detected. Together with an assigned sensor detection signal the exact location can be determined.
  • the evaluation unit according to claim 4 can be a distance measuring unit comprise, wherein two sensor signals are evaluated, the successive Vehicles are assigned, which simply means a relative distance the vehicles can be determined.
  • the sensor signals of the ultrasonic sensors according to claim 5 also evaluated in their signal intensity. Because different vehicle types have different reflection intensities for ultrasound can be in a vehicle type recognition unit different vehicle types can be distinguished. In order to can, for example, be advantageously differentiated as to whether one is left behind Vehicle is a motorcycle, a passenger car or a truck, which may represent different potential dangers and also different ones Reactions required. Vehicle type recognition can also be used, for example be used for statistical purposes.
  • the evaluation unit can be simple a counting unit can be included with which a vehicle count can be made via the sensor signals is feasible.

  • the lanes in one direction preferably each assigned to a single lane and breakdown spaces are.
  • the assignment provides a much more meaningful monitoring an ultrasonic sensor row for each individual lane in one direction.
  • the sensor distances can be up to approx. 10 m, whereby approx. 50 Ultrasound pulses are emitted and received every second.
  • the sensor signals especially if the intensity of the sensor signals is to be digitized for electronic evaluation in the usual way.
  • a / D converter already attach the ultrasonic sensors and the digitized signals over a to forward the serial bus system to the evaluation unit.
  • ultrasonic sensor a certain sensor signal comes from in a manner known per se requires a sensor detection signal together to send the measurement signal to the evaluation unit.
  • a two-wire system can be used, via which also the voltage supply of the ultrasonic sensors and the A / D converter is feasible. Only one voltage supply is particularly advantageous for this required in the low-voltage range, so that no further Can pose security risks for tunnel operation.
  • a signal transmission from the ultrasonic sensors to Evaluation device can be provided via radio. This will depend on the circumstances the installation effort can be further reduced and a flawless Signal transmission also in the event that possibly at a Fire cables could be destroyed.
