Definitions

  • the invention relates to a device for monitoring the speed limits of road users, in which the speed of the individual road users is measured by means of a speed detector and the road users are detected by means of an image recording device, the image recording device being controlled by means of a control unit which can be activated by the speed detector, and the recorded images in transmitted to a control center and stored there in a central image memory and can be called up via a screen unit.
  • each surveillance camera is always in operation and connected to the surveillance center via an elaborate video line, which is also limited in length without additional devices.
  • the use of such a device along very long traffic routes, for example motorways, is therefore not possible. It is therefore an object of the invention to provide a device of the type mentioned in the introduction, in which on the one hand the regular maintenance by police officers is dispensed with and on the other hand a simple transmission network, which is already available if possible, can be used to transmit information.
  • traffic congestion and ghost drivers should be detectable and immediate measures can be initiated immediately.
  • the image recording device is a television recording camera in a manner known per se, that an external system is connected to the television recording camera, which contains the control unit, an image memory connected to the television recording camera and a transmission unit connected to the control center via a transmission medium, wherein the control unit controls the image memory and the transmission unit connected to it, as well as the television recording camera, so that the central unit is connected to the outdoor systems via a central transmission unit, the central transmission unit being connected to the display unit and the central image memory, in the event of an overshoot or undershoot the speed limits, the control unit switches on the television recording camera for the duration of an image sequence and causes the memory to store the recorded image that the control unit has a unit it causes a short message of this event to be transmitted to the display unit via the transmission unit, the transmission medium and the central transmission unit, that after the short message has been transmitted the control unit causes the memory, read out the stored image data and transfer them to the central image memory via the transmission unit, the transmission medium and the central transmission unit.
  • the transmission unit in the outdoor facility converts the image information into a signal form that is suitable for transmission on existing AF lines, such as the breakdown and emergency network on highways.
  • the image recording camera and image memory are only in operation in the acute case, namely when the speed detector reports that the speed has been exceeded.
  • the short message immediately informs the official at the headquarters about the type of misconduct by a road user.
  • a message memory is connected to the central transmission unit. This means that the short messages can also be logged. If the message contains the address of the outdoor facility as well as the date and time of the event, the official at the headquarters is also informed of the location and the automatic log in the message memory also contains the time of the misconduct.
  • Another embodiment of the invention is that when a speed limit is exceeded, the control unit causes the television recording camera to take two pictures within a defined short time interval. This ensures that the fast driver is clearly recognizable in recordings that show several road users.
  • the time interval between the two recordings must be relatively large. In order nevertheless to be able to reliably depict road users at a greatly increased speed on both images, it is advantageous if, according to a development of the invention, the time interval can be regulated depending on the measured speed of the road user.
  • the control device recognizes several speed thresholds. Not only can speed detectors be detected, but the device can also be used for traffic counting when the threshold is in the low speed range.
  • a threshold at 0 km / h detects the traffic standstill and reports a traffic jam.
  • control device also recognizes the direction of movement of the vehicle according to a further embodiment, the device can also be used to detect so-called ghost drivers.
  • the transmission unit of the outdoor system and the central transmission unit contain modems for monitoring data outside the voice band.
  • the existing service is not disturbed, since the image and message data are transmitted outside the voice frequency band.
  • the transmission unit contains a data compressor.
  • a corresponding data expander is connected in the center between the central image memory and the screen unit. This arrangement also stores the compressed image data in the central image memory, thereby saving storage space.
  • the transmission unit contains an encryption device.
  • the decryption device is connected between the central memory and the screen unit. This prevents the data from being changed by unauthorized persons during transmission and storage without being recognized.
  • an alarm device is connected to the central transmission unit according to a development of the invention. Depending on the type of message, a different alarm can be triggered.
  • Another embodiment of the invention provides that an alarm device is connected to the signaling unit in the outdoor area, which is connected to a transmitter for the police radio network. Due to the decentralized alarm device on site, emergency vehicles are alerted during the transmission to the central, which can quickly take countermeasures.
  • a speech processor is connected between the alarm device and the transmitter.
  • the alarm device is expediently connected to warning devices on the traffic route. For example, a warning of a ghost driver can be passed on to other road users or to the ghost driver immediately after detection by existing warning devices. This happens automatically and above all without delay.
  • a further embodiment of the invention provides that a message counter is connected to the message unit of the outdoor system.
  • Weiers can have the central reporting unit connected to higher-level bodies via a public data network, for example the Datex-P network. This offers e.g. the possibility of central statistics.
  • a further development of the invention provides that the outdoor area is set up on one-way lanes after the driveway has merged into the lane. This means that, above all, those road users who attempt to reach the missed departure again in reverse gear, ie against the facility lane, can be detected after they have left the carriageway.
  • the television recording camera is equipped with an infrared recording tube
  • the device according to the invention is ready for use even in poor visibility conditions, for example at night or in fog.
  • the device consists of decentralized outdoor systems 1, which are connected to the center 2 via existing telephone lines 12.
  • a radar system 4 is used for measurement the speed of road users. If a speed is determined outside the predetermined limits, the control unit 5 activates the television recording camera 3 and the memory 6 for the recording and storage of still images.
  • the control unit 5 reacts to four different types of signaling of the radar when used on motorways. From 130 km / h a speed limit is detected, from 40 km / h the radar system sends impulses for traffic counting, in the border area around 0 km / h traffic standstill is detected and a ghost driver is detected at a negative speed.
  • the television recording camera 3 sends a complete still picture to the memory 6.
  • the image memory 6 is a circular memory with a capacity of, for example, 128 kB, which enables the storage of 3 double images.
  • the control unit 5 also sends a pulse to the message unit 13 and to the message counter 17.
  • the message unit 13 sends a short message based on this pulse via the protocol converter 14, which is responsible for data backup on the transmission link, to the modem 16.
  • the modem 16 is for example a Data-over-Voice (DOV) modem, which transmits the data information above the voice frequency band via the line 12 to the control center.
  • DOV Data-over-Voice
  • the short message can also be sent to the police radio network 31 via an alarm device 19.
  • a police radio transmitter 21 is connected to the reporting unit 13 via a speech processor 20.
  • the short message is converted into analog voice signals and these can then be received and evaluated directly by the emergency vehicles without additional devices.
  • the image data stored in the image memory 6 can be transmitted.
  • the image signals are after a conventional method in the data compressor 15 compressed to limit the amount of data to be transmitted without impairing the image quality, and then encrypted in an encryption device 32.
  • the purpose of encrypting the data is to prevent image manipulation during transmission as well as at the headquarters.
  • a timer unit 18 also adds the corresponding information about the date and time of the image recording to the image data.
  • the image and calendar data are sent to the protocol converter 14, which ensures secure data transmission via the DOV modem 16 and the transmission link 12.
  • the DOV modem 22 receives the short message sent by the branch office 1. This is checked by the protocol converter 14 for transmission errors and transmitted to the reporting unit 24. Depending on the type of event, the reporting unit 24 triggers an alarm via the alarm device 27. In addition, the short message is sent via the screen interface 25 to the screen 9 in order to draw the operator's attention to the event that has occurred.
  • the content of such a short message could be, for example: Motorway km 154, direction Salzburg, speeding 186 km / h.
  • this short message is forwarded to the log recording 34, which stores all the short messages chronologically on a message memory 11.
  • the log recording is used for statistical purposes.
  • the image data arriving after the short message are fed to a central image memory 10 via the DOV modem 22 and the protocol converter 23.
  • the data is not decrypted and not expanded. If the operating personnel wants to output a recorded image to the screen or the printer, the image data are read out from the central image memory 10, decrypted in the decryption device 33, expanded in the data expander 26 and then fed to the screen unit 9 or the printer 28 via the screen interface 25.
  • the screen interface 25 ensures the input / output option, checks the password the operator and checks the authorization for the corresponding commands.
  • Datex-P connection 29 processed information, such as statistics, etc., can be passed on to higher-level locations via the Datex-P network 30.
  • a Datex-L connection or a modem connection can also be provided, depending on the requirements.
