Definitions

• train journeys on railways have grown historically largely on the basis of stationary signals which, depending on the route elements in accordance with the agreed signal order, prohibit driving or give a driving license, possibly with indication of the route or the permissible driving speed Transmitting the driver visually.
• a high level of safety of the railways could be guaranteed up to speeds of 160 km h, in particular in addition to technical devices to avoid passing signals indicating "stop".
• the high safety-relevant requirements lead to very high investment and operating costs in the technical systems currently used, which is particularly critical in the case of lower operational requirements, such as on routes with weak or moderate operation, because despite the recognized advantages of rail transport, the competition ⁇ ability to other modes of transport is significantly restricted.
• the object of the invention is to propose a method and a device which make it possible for safety-relevant acquisition, processing and visualization of status information of decentralized or central control devices on traction vehicles, which are used to issue a driver's license, to be carried out at low cost, wherein the train operation can only be carried out by radio and largely without fixed signals.
• this object is achieved in that when a driver's license for a specific route is requested by the driver in the on-board computer of a locomotive system, a stored, determined, non-interruptible program sequence is started, whereby the state of the decentralized or central control units of the route elements is successively used by radio determined and stored in specified storage locations of the on-board computer as status information.
• defined reference information is stored for each route in other specified storage locations.
• the determined status information is compared with one another and / or with the corresponding reference information as part of the determined program sequence, according to defined mathematical or logical conditions. Depending on this comparison, a safety-relevant visual representation of the driver's license on the motor vehicle device for the driver takes place when the conditions are met.
• the device according to the invention for implementing the above-described method is a locomotive device which is arranged on the locomotive and essentially consists of an operating device, a display, an on-board computer, a radio modem connected to it and a mobile radio terminal.
• a two-button operation by the driver of the driver triggers the request for a driver's license for a specific route via the operating device, whereby a program sequence which is permanently determined in the on-board computer is started.
• This causes the control units responsible for the driver's license, the state of which is object-oriented, to be selected one after the other via the radio modem and the mobile radio terminal is queried and the status information obtained is stored in the memory locations of the on-board computer which are permanently assigned for the queried control units.
• the status information is compared with one another within the determined sequence and to ensure that it matches the reference information stored in other storage locations according to specified conditions. If the specified conditions are met successfully, a driver's license for each route element, in addition to the route shown, is shown on the display.
• the device according to the invention can also be constructed in terms of hardware in terms of hardware on the basis of the method assurance shown, taking into account the high demands on signal-technical security, since the result of the driver's license request is that the comparison of spatially separated and thus completely independent object-oriented status information in succession and / or with reference information is consistent until the driver's license is visualized on the locomotive display.
• Any security requirements can be met via the scope of the data record of the object-oriented status information and the given probability of the occurrence of independent random misinterpreted status information.
• the non-interruptible determined process further ensures that any status information that is not correct in terms of time and storage space does not lead to a driver's license. Redundancies could possibly be of advantage only in the interest of increasing availability.

• Each route protection device relevant for the respective route is selected one after the other via the radio modem 3 and the mobile radio terminal 4 and its status is queried in an object-oriented manner - and train tracks by the last train give a certain status report.
• the incoming status information is stored in the on-board computer 2 in permanently assigned storage locations. Whether a driver's license is permitted for the requested route is checked within the determined program sequence in that the received and stored status information of the route safety devices is determined according to each other and / or in relation to one defined for this route Reference information can be compared.
• the reference information is also stored in fixed memory locations of the on-board computer 2. For the check of the admissibility for the issue of a partial driving license, the condition to be fulfilled is, for example:
• X and Y represent 1st and 2nd status information and R the corresponding reference information. If this condition is met, a partial driver's license is visually shown on the display 5 for the driver for the route in question.
• any other mathematical operation can be carried out for other partial information of the driver's license in the interest of the disclosure of the error and the reference information “R” can be defined. More than two status information can also be used.
• FIG. 2 shows the method according to the invention for a train journey of the traction vehicle Tfz. 01 explained on a single-track route from station A-Stadt to train station B-Stadt on the basis of the illustration shown on the display 5 to the driver.
• the display basically shows the route, the vehicles on it and the driver's license issued, whereby the driver's license issued for the corresponding route, preferably green, is shown next to the route shown:
• the driver requests a driver's license for the route from station A-Stadt to station B-Stadt via a two-button operation on operating device 1 of on-board computer 2.
• the on-board computer 2 starts the determined program sequence stored for this route.
