Definitions
- the invention relates to a method for monitoring a rail-bound means of transport in the preamble of the claim 1 specified type and an arrangement for implementation of the procedure. Such a method is described in the publication EP 0310 705 A discloses.
- DE 27 04 143 A1 describes a device for influencing lines Known at which data telegrams from the moving Rail vehicle to the outside by means of a transmitter BS of the train, with a fixed control station OFS connected receiving devices positioned along the route of the train S1 to S9 are transmitted when the train is located in the area of the respective receiving device.
- the route is in partial areas, each of which has a receiving device S1 to S9 is assigned divided.
- Each section represents a radio zone with a radio channel exclusively assigned to it, so that transmitting and receiving devices with comparatively short ranges and low complexity can be.
- the radio zones are designed so that these overlap slightly and thus seamless data transmission ensure if the vehicle is along the route moved from one section TB to the next.
- DE 195 38 022 C2 describes a device for controlling a Rail vehicle described, in which the signaling systems of the respective route section are checked.
- the signal state the respective system must be from an image capture device (Camera) can be recognized.
- image capture device Camera
- In a memory of the rail vehicle device data before the start of the route about the positions of the signal systems, with their possible signal states, of the route sections saved.
- the current Location of the rail vehicle via satellite or position sensors (Induction loops) along the route.
- the data processing device fetches on the basis of this information the data of the associated route section from the Storage.
- the future positions of the signal systems of the Route section are thus known. Look at this the signal states of the respective signal systems are recognized and on corresponding behavior of the speed causes.
- Arrangements are used in railway operations that are for visual purposes Serve monitoring.
- Surveillance is used in the station area the avoidance of personal injury and property damage at level crossings for remote control of the barriers from a control center.
- the invention has for its object a method for train monitoring of the aforementioned type and specify an arrangement for carrying out the method with which it is possible to visually and can be observed acoustically.
- Transfer of surveillance of a moving, rail-bound train to a control center is independent at all times feasible from the location of the train.
- the transfer becomes one by an alarm device in the car or the other by requesting the supervisory staff in the control center triggered so that a transmission takes place only if this is necessary or desired.
- the recording of the video information is carried out in wagons carried out, each car or group of cars the train to be monitored has its own image recording device, for example a video camera and an image processing unit having.
- the recording device is in Car interior positioned to the behavior of those located there Capturing people in the picture, possible criminal acts to be able to register immediately and take first countermeasures to be prepared by the control center connected to the receiver.
- An arrangement of the receiving device on the outer wall of a or several freight wagons when monitoring a freight train enables an advantageous development of the Invention a control of the carload and the surrounding area of the corresponding car, so that, for example, loosening a tarpaulin attached to protect the cargo or a criminal Activity of unauthorized persons on the corresponding car can be recognized in time.
