Device for monitoring train completeness in locomotive-hauled

Trains

The invention relates to a device for monitoring the completeness of locomotive-hauled trains by using acceleration and pressure sensors.

Deutsche Bahn AG, like some other European railways, wants to make future railway operations more economical through further automation.

As part of these efforts, a new "European Rail Traffic Management System" (ERTMS) is being designed at European level, with the "European Train Control System" (ETCS) planned as its core. This and other new operational control systems are based on a largely route-independent control and safety system.

To secure the route, these systems require the component "Train Integrity Monitoring System" (ZVS), which can be used to monitor the integrity of the train formation.

The ZVS described here consists of a train termination device with a detachable, rigid attachment to an end car and a permanently integrated locomotive device, which are connected to each other via cables or radio for communication.

With the current safety and control technology of DB AG, the routes are divided into block sections. For example, when entering a block section, the axles of the train are counted by axle counters, and this happens again when leaving. If the number of axles is identical, the previous section is reported free for the following train.

This procedure ensures at least selective monitoring of the train, but this means that the trains can only travel at block intervals. This means that the route is not optimally utilized.

In GM DE 297 09 702 U1, a solution approach with measuring devices for determining the position and/or the speed is proposed. In OS DE 44 13 114 A1 and in European patent application 0 678 437 A2, an internal train end detection system is described, also with a measuring device for determining the speed.

These monitoring systems are inadequate because the solutions focus exclusively on speed and location and do not include the only existing continuous medium of each train, the main air line (18), in the solution considerations, nor do they take longitudinal acceleration into account.

The object of the invention is to provide a possibility with which an economical solution can be achieved while avoiding the disadvantages of the prior art. This object is achieved by the subject matter of claim 1. Further advantageous embodiments are contained in claims 2 to 8.

The invention is explained using an embodiment shown in the drawings.

The train end device (1) contains a sensor for determining the air pressure (6) of the train's main air line (18), a sensor for determining the longitudinal acceleration (5), a sensor for determining the free distance to the rear (20), a processor (4) for suitable preprocessing and compression of the measurement data, a rechargeable, battery-buffered power supply (8) and a transmitter (2) for transmitting the measurement data to the locomotive. A topographical route map (7) can be used to assess the acceleration signals.

The values received from the train end device (1) by a receiving device (12) in the locomotive are compared with the values obtained in the locomotive from a compressed air sensor (15) on the main air line (18) and a sensor for determining the longitudinal acceleration (14) with a processor (13) in terms of levels and curves and processed together with status information from the vehicle control (16), such as the position of the driver's brake valve and the control lever, and from this a message about the status of the train is generated.

To reliably detect the end of the train, a distance sensor (20) or a blocking hook in the coupling of the last car is recommended. Existing electrical or optical connecting cables (19) can be used to transmit the information.

The train end device (1) should be attached detachably and rigidly to the fastening of the train end disc and contains a charger (10) and a battery (9). Between the train end device (1) and the locomotive evaluation system (17) there is the possibility of transmitting data from the locomotive device for control and communication using the train end device receiving device (3) and the transmitter device (11).
