- the invention further relates to a control device for communication-based vehicle control of at least one lane-bound vehicle and a driving distance-saving vehicle, wherein the control device is designed to generate control instructions, and wherein the control statements by data communication by means of a communication nikationsnetztechniks, the more the driving distance together covering communication cells, are transmitted.
- control instructions are transmitted via wireless data communication from route-side devices to vehicle-side devices.
- Conceivable would be a data communication between the vehicles.
- technologies such as WLAN, GSM-R, UMTS, LTE or the like are used.
- the object is achieved for the method mentioned in that it is checked for the communication cells, whether sufficient data communication in the respective communication cell is possible or available, and the result of the test is taken into account in the vehicle control.
- control device is designed to generate the control instructions.
- the control device is designed to generate the control instructions.
- the solution according to the invention has the advantage that, in the event of insufficient data communication in a communication cell lying in front of the vehicle, preventive measures can be taken to minimize the vehicle influence. These are taken into account in the generation of the control instructions and taken into account, for example in the form of an altered driving profile with changed speeds or routes.
- Whether sufficient data communication in the respective communication cell is possible means that the relevant communication cell is not overloaded with respect to data communication, but additional data communication between the trackside and vehicle-side device can be established. This must be established, namely, when the vehicle enters the communication cell. So you could also speak of a sufficient availability of data communication.
- the communication network used for the communication-based vehicle control is subdivided into a plurality of communication cells, which together cover the planned route of the vehicle. This applies both to a CBTC system and, for example, to an ETCS system. In this case, only the size of the communication cells is different. In any case, the possibility or availability of data communication in the control of vehicles is taken into account early, so that unplanned stops of vehicles can be avoided.
- the solution according to the invention can be further developed by advantageous embodiments, which are described below.
- prognostic be whether or not sufficient data communication in the respective communication cell will be available, and the result of the forecast is taken into account in the vehicle control.
- This has the advantage that in the case of communications cells lying ahead of the vehicle with failed data communication, it can be estimated when they will be available again.
- the speed of the vehicle can be adjusted so that it only arrives in the communication cell when the data communication is available again.
- Such a prognosis can be made, for example, by deducing past operating data on the immediate future.
- At least one property that is representative of a quality of the data communication within the communication cell can be measured.
- a signal-to-noise ratio, a signal level, a packet error rate and / or a number of successfully transmitted test packets can be measured in each communication cell.
- Limit values can be determined from which the quality of the data communication is considered to be too low or sufficient.
- a representative sentativer value can also be determined from several measured properties.
- a planned route of the vehicle can be taken into account in the vehicle control.
- the planned route can, for. B. are provided by a control center or the Steuerungseinrich device anyway known.
- a planned route and / or a running profile of the vehicle may be changed. This has the advantage that disturbances of the ferry operation can be minimized because a vehicle does not even drive into a communication cell in which the data communication is not available.
- the amount and / or the type of the transmitted data may be changed. For example, the transmission of less relevant data, such as video streaming for a vehicle or track-side video archive, can be prevented so that possibly low data communication for the communication-based vehicle control is available and a breakdown of the data communication is thereby avoided.
- the low data communication can namely be sufficient for the transmission of the control instructions.
- the invention further relates to a system for communication-based vehicle influencing of at least one track-bound vehicle driving along a route, with a control device which is designed to generate control instructions for vehicle control, with at least one track-side communication device and at least one vehicle-side communication device, wherein the vehicle-side Kirunikationsein direction and the track-side communication device are formed, via at least one communication network, comprising a plurality of communication cells to transmit the control instructions via data communication.
- the Steuerungsein direction is inventively formed according to the above fiction, contemporary design.
- the latter can have at least one device which is designed to measure at least one property for each of the communication cells, which is representative of a quality of a communication connection. Suitable properties are especially those already mentioned above.
- the single figure shows schematically an exemplary imple mentation of a railway technical system 1, the least one vehicle 2, a route 3 and a system 4 for communication-based vehicle control includes. For simplicity, only a vehicle 2 and a very simple route 3 is shown.
- the vehicle 2 is, for example, a locomotive, a train, a subway, a suburban train, a tram or another tracked vehicle and moves in operation on the route 3.
- the route 3 is, for example, a track system constructed with rails and can Of course, not shown branches with switches and the like, as is well known.
- a communication network 7 is formed, which consists of a plurality of communication cells 8.
- the communication cells 8 are radio cells that For example, by WLAN, GSM, GSM-R, LTE, 5G or a similar wireless network technology are constructed.
- the radio cells are shown only schematically and can, depending on the application z. B. at CBTC about 200 - 500 m and at ETCS about 5 km in size.
- Control instructions 9 can be transmitted wirelessly via data communication between the vehicle-side communication device 6 and the track-side communication devices 5.
- the communication network 7 the data communication between the vehicle 2, while it moves on the route 3, and the track-side commu nikationss learneden 5 ensured.
- the eisenbahntechni cal system 1 is for a communication-basedsammlungbe influence, z. As CBTC or ECTS, trained in the
- Control instructions 9 are transmitted to the vehicle 2 while driving.
- the system 1 further includes a control device 10 which is connected to the trackside communication devices 5 and generates and outputs the control instructions 9 for the vehicle 2.
- the Steue guiding device 10 determines which route 3 the driving tool 2 travels and, for example, with which speed VELOCITY.
- Corresponding instructions are transmitted to the vehicle 2 in the form of the control instructions 9.
- the stre cken workede communication devices 5 may be part of route computers, the vehicle-side communication device 6 part of a vehicle computer.
- a device 11 is arranged in the presented in the figure Darge embodiment, which measures one or more properties in the communication tion cell 8 in operation, which is representative of a quality of Kommunikati onsimpl in the communication cell 8.
- This property which is representative of the quality, is, for example, a signal-to-noise ratio.
- a signal level, a packet error rate and / or a number of successfully transmitted test packets can also be measured.
- the devices 11 measure continuously z. As the signal-to-noise ratio and compare this with a set limit. By comparing with the threshold value, the device 11 determines whether the quality of the communication link in the corresponding communication cell 8 is sufficient for the transmission of the control instructions or not. If the quality is sufficient, sufficient availability of the data communication in the respective communication cell 8 is assumed. This sufficient availability is reported to the control device 10.
- the comparison based on the measured values can of course also be carried out in the control device.
- the controller 10 is for each communication cell 8 along the route 3, a message as to whether sufficient data communication is available. If the se is available in all communication cells 8 along the route 3, the vehicle 2 can continue its journey without restrictions. However, if there is no sufficient availability of kommunika tion for any of the communication cells 8, the control device 10 will consider this fiction, according to the vehicle influence and send corresponding control instructions 9 to the vehicle 2 from. Thus, for example, the driving profile for the driving tool 2 can be changed to prevent entry to the communication onszelle 8 with unavailable data communication to ver. For example, the maximum speed of the vehicle 2 can be reduced by appropriate control instructions 9. Alternatively, a new route (not shown) for the vehicle 2 could be selected to bypass the communication cell 8 with unavailable kommuni cation.
- forecasts are made for the communication cells 8 when, for example, an unavailable data communication is again available or an available data communication is no longer available. This forecast is made by the devices 11 for measuring or by the Steuerungsein device 10 itself employed. The device 11 may of course be integrated in the components of the communication cells 8, for. In the routers.
- each communication cell 8 By means of the devices 11, the possibility is implemented in each communication cell 8 to continuously determine the quality of the data connection. In addition, this quality of data communication can also be predicted or predicted. This makes it possible to deduce the future availability of the data communication in the respective communication cell 8. Furthermore, the control device 10, the planned route 3 for each vehicle 2 is known. As a result, the control device 10 can control each vehicle 2 in such a way that entry into a communication cell 8 with insufficient data communication can be avoided.
- the controller 10 is thus for each communication onszelle 8, the information as to whether a data communication is available or not.
- the con crete measurement result of the devices 11, for example, the measured signal-to-noise ratio, device 10 to the Steuerungseinrich be transmitted.
- the railway technical installation 1 shown in the figure thus has an inventive system for kommunikationsba-based vehicle control.
- the system includes the controller 10, the trackside communication devices 5, and the vehicle side communication device 6, as well as, in this embodiment, the devices 11 for measuring the characteristic.
