Abstract
A railway vehicle-side communication device for a railway vehicle for communicating with a trackside communication device. The trackside communication device has at least two communication modes, namely, a first communication mode having a first data transfer rate and a second communication mode having a second data transfer rate that is higher than the first data transfer rate. The railway vehicle-side communication device has a switch-over element setting the second communication mode in or in the vicinity of a station for communicating with a station-side communication device and setting the first communication mode outside of a station for communicating with a track-side communication device.
Description
- The invention relates to a communication device on the rail vehicle side for a rail vehicle for communication with a trackside communication device.
- By way of example, communication devices such as these are known in conjunction with automatic train control systems which allow the train to be controlled by trackside control or monitoring centers.
- Against the background of a communication device such as this, the invention is based on the object of developing this device further such that more data than in the past can be transmitted in total during operation of the rail vehicle.
- According to the invention, this object is achieved by a communication device on the rail vehicle side as claimed in patent claim 1. Advantageous refinements of the communication device according to the invention are specified in dependent claims.
- The invention accordingly provides that the communication device on the rail vehicle side has at least two communication modes, specifically a first communication mode at a first data transmission rate and a second communication mode at a second data transmission rate, which is higher than the first data transmission rate, and in that the communication device on the rail vehicle side has a switching device which selects the second communication mode in the station or in the vicinity of a station for communication with a communication device on the station side, and selects the first communication mode outside a station, for communication with a trackside communication device.
- One major advantage of the communication device according to the invention is that this device allows larger amounts of data to be transmitted than previous communication devices. Specifically, this is because the communication device according to the invention provides two communication modes which are each matched to the respective location of the rail vehicle. Specifically, when a train is on a track between two stations, the maximum data transmission rate when the rail vehicle is travelling at high speed is generally limited for technical reasons, which means that only a relatively low data rate can be transmitted while operating between the stations. In contrast, when the rail vehicle is moving only slowly or is stationary, as is the case in the station area for example, then higher data rates can be achieved, which means that relatively large amounts of data can be transmitted overall as well, in a relatively short time. This is the purpose of the invention, which provides for the communication device on the rail vehicle side to have a switching device which selects a location-specific communication mode depending on the location of the rail vehicle. In this case, in the station area, while the rail vehicle is quite slow or is stationary, a high data transmission rate is selected and, in the area outside a station, a lower data rate than this is selected, in order to allow error-free or low-error data transmission at relatively high speeds.
- A further major advantage of the communication device according to the invention is that it can be used even when the operator wishes to use high bit-rate data transmission, as is required for example with driverless rail vehicles and/or in the case of video monitoring of the rail vehicle interior from the track.
- The operating mode switching can be carried out particularly easily and therefore advantageously by the switching device being connected to a motion or speed sensor and being designed such that it switches from the first to the second communication mode when the rail vehicle is travelling at less than a predetermined speed, and switches from the second to the first communication mode when the rail vehicle is travelling above the predetermined speed. In this advantageous refinement of the communication device, the communication modes are therefore switched as a function of the speed, with the speed being used to decide whether the rail vehicle is or is not in a station area.
- Alternatively or additionally, the switching device can also be connected to a position determining device and can be designed such that it switches from the first to the second communication mode when the position determining device signals proximity to a station, and switches from the second to the first communication mode when the position determining device signals a track outside a station. By way of example, a position determining device such as this may be formed by an automatic train monitoring system or may comprise such a system; specifically, for the purposes of automatic train monitoring, a continuous determination is made as to where a rail vehicle is located, thus resulting in a position definition signal by evaluation of the corresponding measurement signals, which position definition signal can be used to select the correct communication mode.
- In addition, the switching device may also itself be suitable to use received signals which are received from trackside communication devices to determine whether these devices form a communication device on the station side or a trackside communication device. The switching device can make such a decision on the basis of the received signals for example by evaluating the Standard used as the basis for production of the received signals, and/or the transmitted powers of these signals and/or what specific reception characteristics can be identified.
- The communication device preferably has at least two transmitting and receiving devices, which are arranged at a distance from one another in the rail vehicle, in the vehicle longitudinal direction, in the vehicle lateral direction or one above the other, or one below the other. This is because the fitting of two or more transmitting and receiving devices at a distance from one another in this way allows these devices to be operated with different data, thus allowing parallel data transmission. In this case, the maximum achievable data rate is governed by the number of transmitting and receiving devices multiplied by the data rate of a single transmitting and receiving device.
- If the rail vehicle is a train, then it is considered advantageous for at least one transmitting and receiving device to be arranged in or on the front vehicle of the train and/or at least one transmitting and receiving device to be arranged in or on the rearmost vehicle in the train.
- Irrespective of how many transmitting and receiving devices are provided on the rail vehicle side, it is considered to be advantageous for them to be arranged offset, in particular in the vehicle longitudinal direction, such that the distance between the transmitting and receiving devices is greater than the interference range, which can be determined for example by the transmitted power, in the vehicle longitudinal direction.
- Because the aim is to transmit as large an amount of data as possible, it is considered to be advantageous for data which is as different as possible, even if these are not data items which are necessarily independent of one another, to be transmitted via a plurality of transmitting and receiving devices, and as far as possible to avoid redundancy.
- In order to allow parallel transmission of data for station operation, it is considered to be advantageous for the transmitted power of the communication device on the rail vehicle side to be lower in the second communication mode than in the first communication mode; this is because a refinement such as this ensures that the individual transmitting and receiving devices in the communication device on the rail vehicle side cannot interfere with one another when they communicate with the communication device on the station side by being operated in parallel.
- The communication device on the rail vehicle side preferably has one or more reception filters whose reception sensitivity is variable, in order to allow an optimum reception quality to be selected; in this case, the communication device is preferably also designed such that it selects the reception sensitivity as a function of the respective communication mode, to be precise such that the reception sensitivity in the first communication mode is higher than in the second communication mode. Sensitivity control such as this is particularly advantageous when the aim is to carry out parallel data transmission using a plurality of transmitting and receiving devices at the same time in the second communication mode, that is to say in the station area, with the aim of avoiding mutual inference or disturbances.
- The communication device on the rail vehicle side particularly preferably also has at least one infrared transmission device which can communicate in the second communication mode with a corresponding infrared transmission device on the station side.
- The communication device is preferably equipped with at least two infrared transmitting and infrared receiving devices which are arranged at a distance from one another in the rail vehicle, in particular in the vehicle longitudinal direction. A refinement or arrangement of the infrared transmitting and infrared receiving devices such as this allows data to be transmitted in parallel by optical means, thus allowing very large amounts of data to be transmitted overall.
- It is also considered to be advantageous for the communication device on the rail vehicle side to be equipped with a radio transmission device which—for example for the first communication mode—can communicate with a trackside communication device by radio. By way of example, a refinement such as this makes it possible to transmit data in the station area by infrared light, and on the track by radio.
- Furthermore, it is possible to design the radio transmission device on the rail vehicle side to be switchable in such a way that it is also possible to communicate by radio with a communication device on the station side, to be precise in the second communication mode.
- The radio communication using the second communication mode preferably takes place using a different radio standard than radio communication in the first communication mode. For example, it is possible to transmit data using the WLAN-B Standard with a data rate of between 5 and 10 Megabits per second on the track and to select the WLAN-G Standard, with a data rate of 50 Megabits per second, in the station area.
- Furthermore, the invention relates to a rail vehicle which is equipped with a communication device on the rail vehicle side as described above.
- Furthermore, the invention relates to a communication system having a communication device on the rail vehicle side, as has been described above, having at least one communication device on the station side, and at least one trackside communication device, wherein the trackside communication device has a first communication mode at a first data transmission rate, and the communication device on the station side has a second communication mode at a second data transmission rate, which is higher than the first data transmission rate.
- With regard to the advantages of the communication system according to the invention, reference should be made to the above statements in conjunction with the communication device according to the invention, since the advantages essentially correspond to one another.
- With regard to the communication system, it is considered to be advantageous for the communication device on the rail vehicle side to have at least two transmitting and receiving devices which are arranged at a distance from one another in the rail vehicle, in particular in the vehicle longitudinal direction and, when there are at least two transmitting and receiving devices on the station side, for them to be arranged offset, in particular in the station longitudinal direction. The distance between the transmitting and receiving devices on the rail vehicle side and the transmitting and receiving devices on the station side is preferably the same, or preferably at least approximately the same, in order that they can form transmitting/receiving pairs with one another.
- In a corresponding manner, it is considered to be advantageous for the transmitting and receiving devices on the station side to be arranged such that the transmitting and receiving devices on the rail vehicle side and the transmitting and receiving devices on the station side are opposite in pairs when the rail vehicle has reached its stopping position in the station. The corresponding transmitting and receiving devices on the station side may, for example, be arranged in the track bed or in the platform area.
- The transmitting and receiving devices on the station side are particularly preferably infrared transmitting and infrared receiving devices, since these can transmit relatively high data rates over short distances and are relatively insensitive to interference in the process.
- Furthermore, the invention relates to a communication device on the station side as can be used, for example, for the described communication system, wherein the communication device has at least two transmitting and receiving devices which are arranged at a distance from one another in the station longitudinal direction.
- With regard to the advantages of the communication device on the station side, reference should be made to the above statements in conjunction with the communication device according to the invention on the rail vehicle side, and the described communication system according to the invention.
- The communication device on the station side preferably has a plurality of transmitting and receiving devices which are arranged offset in the station longitudinal direction, with the distance between the transmitting and receiving devices being greater than the interference range in the station longitudinal direction which is governed, for example, by their transmitted power, orientation or type.
- Furthermore, the invention relates to a method for operating a communication device on the rail vehicle side. For a method such as this, the invention provides that switching takes place from a first communication mode at a first data transmission rate to a second communication mode at a second data transmission rate, which is higher than the first data transmission rate, when the rail vehicle stops in or in the vicinity of a station, and switching takes place from the second communication mode to the first communication mode when the rail vehicle is located outside a station.
