Definitions
- the invention relates to a method for testing ETCS level 2 functionalities in rail traffic.
- ETCS European Train Control System
- OBU on-board unit
- the movement of the rail vehicle is monitored with this OBU module.
- the OBU will also initiate an emergency brake.
- it relies on train data that is known in advance via inputs from the driver of the rail vehicle, as well as on data from the route that it travels through balises and, in the case of "ETCS Level 2", also by radio from a “radio Block Center, RBC "receives. It permanently sends position data to the radio block center so that it can follow the train's course.
- the "Radio Block Center, RBC” is here in the interlocking net or provided to implement the "ETCS Level 2 operation" mentioned above.
- the RBC radio block center receives technical safety data for a route from the interlocking, for example data on the route set, track sections occupied, etc.
- the RBC Radio Block Center determines the applicable safety information for each rail vehicle located in the control area of the signal box.
- the security information determined for a predetermined rail vehicle is transmitted from the radio block center RBC to the on-board unit OBU of the associated rail vehicle.
- This transmission is carried out using a radio link, preferably via the known GSM-R system.
- ETCS Level 2 constant communication between the rail vehicle and an ETCS control center or signal box is provided via Euroradio.
- a radio block center RBC is required to test ETCS Level 2 functionalities in the field, but it is only intended for regular operation on a certain route.
- Test drives are only possible on certain routes and at certain times. As a rule, advance registrations are required and fees are due. In some projects, complex transfers are also necessary. - Cooperation with a dispatcher in the signal box is required, which may compete with normal operation on the test track.
- the arrangement according to the invention is used to test ETCS level 2 functionalities in rail traffic.
- an on-board unit OBU is provided as the first assembly.
- this first assembly monitors the movement of the rail vehicle as an OBU assembly.
- the OBU module also initiates an emergency brake.
- train data that is known in advance via inputs from the driver of the rail vehicle, as well as on data from the route that it travels through balises and, in the case of "ETCS Level 2", also by radio from a "radio Block Center, RBC "receives. It permanently sends position data to the radio block center so that it can follow the train's course.
- the first module has a connection for a GSM-R radio link.
- an adapter is seen as a second assembly.
- the adapter is connected to the connector of the first assembly via a data transmission line, so that a GSM-R radio link is simulated for the first assembly.
- the adapter is connected to a computer as a third module via a data transmission line.
- the computer is arranged in the rail vehicle and contains software with which a radio block center RBC of an interlocking is simulated for test purposes in accordance with the ETCS level 2 functionality.
- the ETCS level 2 functionality is simulated between the on-board unit OBU and the radio block center RBC, but without the need for radio transmission.
- simulated data is generated by the computer for test purposes and transmitted to the on-board unit OBU by cable.
- data for test purposes are transmitted back to the computer from the on-board unit OBU by cable.
- the adapter or the computer contains driver software for simulating the GSM-R radio link.
- the rail vehicle is designed for test purposes to travel on a route that has at least two ETCS balise groups.
- the first assembly is designed as an OBU assembly with which the movement of the rail vehicle is monitored.
- the OBU will also initiate an emergency brake.
- the OBU relies on train data that is known in advance via inputs from the driver of the rail vehicle, as well as on data from the route, which it transmits through balises and, in the case of "ETCS Level 2", additionally from a "radio block" - Center, RBC "receives. It permanently sends position data to the radio block center so that it can follow the train's course.
- the computer software that simulates the radio block center is designed to generate data that contain security information on a route or information on the occupancy of track sections.
- the method according to the invention enables test drives to be carried out on normal routes without a great deal of additional effort.
- the method according to the invention also enables test drives on (often very short) sidings. These minor For test purposes, tracks can be booked or occupied by the rail network operator quickly and often with little administrative effort.
- the method according to the invention takes place entirely without cooperation with a dispatcher, so that normal operation is practically not impaired by the test drives.
- the method according to the invention triggers special functions via the RBC simulation at any point so that these functions can also be tested on a siding.
- both error and stress situations can be simulated via the RBC simulation, which are therefore the first time ever to be tested in a field test.
- the RBC simulation is also available in the field, so that tests can also be carried out in the field with the flexibility of a laboratory.
- the method according to the invention increases the product quality, because critical test cases are carried out in the field and, if necessary, carried out repeatedly there.
- the method according to the invention significantly reduces the dependency on the operator or manufacturer of the RBC.
- the invention is explained in more detail below by way of example with the aid of a drawing.
- An on-board unit OBU is provided as the first assembly BG1 in a rail vehicle SZF.
- the first assembly BG1 is designed as an OBU assembly with which, as described above, the movement of the rail vehicle is monitored.
- the first assembly BG1 has a connection AS for a GSM-R radio link.
- An adapter ADP is provided as the second assembly BG2 in the rail vehicle.
- the adapter ADP is connected in a cable-based manner to the connection AS of the first assembly BG1 via a data transmission line DL1.
- the adapter ADP simulates a GSM-R radio link for the first assembly BG1.
- the adapter ADP is connected in a cable-based manner to a computer RE as a third assembly BG3 via a data transmission line DL2.
- the computer RE is arranged in the rail vehicle SFZ and contains software with which, according to the ETCS level 2 functionality, a radio block center RBC of an interlocking is simulated for test purposes.
