Definitions

  • the invention relates to a method for the external monitoring of a means of transport, in which information regarding the means of transport is detected by means of at least one on-board monitoring device, and in which this information is then transmitted and stored to an on-board, centrally located in the transport information recording device, and subsequently transmitted to at least one external central computer and stored in a database connected to the at least one central computer.
  • the invention further relates to a monitoring system for externally monitoring a means of transport, comprising at least one on-board monitoring device for acquiring information regarding the means of transport, an information recording device for receiving and storing the information, and having at least one central computer intended for use in relation to the means of transport for receiving the information from the information recording device and for storing the information in a database connected to the central computer.
  • the term "means of transport” is to be understood as meaning not only so-called public means of transport, but all means of transport, for example, aircraft, ships, buses, rail vehicles and passenger vehicles.
  • Such methods and corresponding monitoring systems are known, for example, for monitoring public facilities and means of transport.
  • the standardized in the law strict data protection requirements only with great difficulties and high financial and technical effort.
  • coaches or passenger trains such as long-distance trains and subways
  • various system solutions are currently used, which are usually based on a video surveillance, in which recorded with several cameras image information and then on a in a than Recording device serving workstation integrated removable hard disk at a central point of the means of transport (for example, in railcar or bus driver) are cached.
  • the known monitoring systems work consistently on the same principle, according to which first surveillance images are taken with a plurality of cameras provided in the means of transport and temporarily stored on the removable hard disk integrated in the recording device. Since, however, the evaluation and / or archiving of the monitoring images usually does not have to take place in the means of transport itself, but in a non-external, external evaluation station, it is necessary to transmit the surveillance images from the on-board recording device to the external evaluation station. This is done manually at the time, namely by replacing recorded during the ride of the transport removable disks with unrecorded removable hard drives and the recorded removable hard disks are manually passed to the evaluation station, then takes place the evaluation of the image data.
  • the on-board monitoring systems also encounter further technical difficulties. These difficulties are due to the fact that the cameras are connected in the individual car bodies of the means of transport via wire-based data lines with the centrally located in the transport recording device. These wire-based or wired systems prove to be problematic if individual car bodies of the means of transport have to be replaced or decoupled during operation. Due to the usually only very limited storage capacity of the removable disks used on-board recording device also the image data of the cameras used for monitoring must inevitably have only a low resolution in order to minimize the memory size of the individual images as possible. Due to this low resolution as well as the frequently competing high data compression, the information content of the individual images is low, which additionally calls into question the meaning and purpose of the conventional monitoring systems.
  • the present invention is therefore based on the technical problem of specifying a method for the external monitoring of a means of transport of the type mentioned above and a corresponding monitoring system, by means of which at an evaluation station arranged externally by the means of transport - with respect to the time of picture taking in the means of transport - almost instantaneously Access to the information captured in the transport image information is possible.

So it is conceivable, for example, that along the route of the means of transport each a non-board central computer is provided at a certain distance to another adjacent alien central computer, the closest to the transport central computer each of the centrally located in the transport, on-board information recording device the receives information to be transmitted.
  • the respective external central computer can be configured as fixedly installed and anti-theft executed individual computer.
  • the respective external central computer can be arranged in stations or on platforms which lie on the planned route of the means of transport.

  • the data recorded in the transport immediately after the automatic transmission of the on-board information recording device to the respective non-external central computer can be supplied to the centrally located database server, and available here as prepared data retrievable.
  • the image data (information) transmitted by the means of transport can also be stored and / or evaluated in the respective central computer, so that this information can be accessed at any time via a network connected to the central computer.
  • the image data recorded in the means of transport are available to the database server immediately after their reception.
  • the traffic-monitoring method according to the invention makes it possible in short time periods to load or transfer the image information stored in the on-board monitoring device to one of the plurality of central computers arranged along the route of the means of transport, so that the image information stored in FIG the on-board information recording device provided image data storage capacity after regular and short periods of time can be released again.

It would also be conceivable here for each data transmission to synchronize the on-board information recording device with the exact time, as a result of which the position of the means of transport, for example with the aid of a GPS system, can be determined at any time and almost in real time. Thus, even in an alarm case, the exact position of the means of transport is always known.
  • the information captured by the on-board monitoring devices, before being transmitted to the on-board information recording device is first transmitted to at least one on-board hub device associated with the respective monitoring devices.
  • This lifting device serves to regulate the information acquired by the individual monitoring devices.
