    Description Field of the Invention The invention relates to a system for brake pressure monitoring of an automatic air brake of a railway vehicle, in particular a freight train. The automatic air brake has a main air line forming a serial, continuous compressed air connection between a leader vehicle and a plurality of carriages attached to the leader vehicle. Further aspects of the invention relate to a corresponding method, a sensor unit of such a system, a receiving unit of such a system, a server of such a system and a corresponding computer program product for a receiving unit of such a system.
    Background [0002] Automatic air brakes are standard brakes on railways. They have a main air line extending serially and continuously from the leading vehicle to the last car of the rail vehicle. As a leader vehicle here are generally understood vehicles, which include the cab of the rail vehicle. This can be both traction vehicles that have a drive, as well as control cars without drive. Traction vehicles in turn include locomotives that serve only the drive and railcars, which also provide space for passengers or cargo. The automatic air brake is often referred to as an indirect air brake. The brake is referred to as automatic or automatic air brake, because it automatically causes the braking of each train part in a train separation.
    The automatic air brake is thus a continuous brake, which can be operated from the cab of the leading vehicle.
    The leading vehicle of a rail vehicle equipped with an automatic air brake typically includes a compressor, a main air reservoir and a driver brake valve. During operation, the compressor presses compressed air into the main air reservoir and compressed air is supplied from the main air reservoir to the main air line via the driver brake valve. A usual control operating pressure is for example 5 bar. Each car of the rail vehicle has at least one auxiliary air tank, a brake cylinder and a control valve. The brake cylinder, the compressed air is supplied indirectly via the control valve from the auxiliary air tank, which in turn is controlled by the main air line pressure.
    The release of the brake is initiated by the train driver by operating the driver's brake valve. However, especially with very long train compositions, it may take some time for the brakes to be released in all cars. However, since the pressure indicator on the driver's brake valve only indicates the local pressure on the driver's brake valve, it happens quite frequently that rail vehicles, in particular freight trains, start off with brakes that have not yet been completely released. This causes considerable damage to the automatic air brakes every year.
    DESCRIPTION OF THE INVENTION It is an object of the present invention to provide a system of the type mentioned in the introduction, which enables improved monitoring of the brake pressure in a simple, reliable and cost-effective manner.
    This object is achieved in a first aspect of the invention by a system according to claim 1. Accordingly, the system has a sensor unit with a pressure sensor for measuring the air pressure in the main air line of the compressed-air brake and with a transmitter for the wireless transmission of sensor data to a server coupled to a network, in particular to the Internet. In addition, the system comprises a receiving unit comprising a receiver for wirelessly receiving the sensor data from the server and an output device, in particular a display device, for outputting the received sensor data to the driver of the rail vehicle. The sensor unit is arranged in the rear part of the rail vehicle, in particular on the last carriage of the rail vehicle. Such a system allows the operator of the rail vehicle to monitor the air pressure / brake pressure in the main air line in a simple, cost effective and efficient manner. For the communication between the sensor unit and the receiving unit no wiring between the leading vehicle and the individual cars of the rail vehicle is necessary. Rather, the transmission is not direct, but via a server that is coupled to a network, in particular to the Internet. The server receives the sensor data, in particular the air pressure, via the network from the sensor unit and then also forwards the sensor data via the network to the receiving unit. The transmitter and the receiver according to the invention are intended to communicate wirelessly with the network. Accordingly, the transmitter is provided to transmit the sensor data wirelessly to the network and over the network to the server coupled to the network. Likewise, the receiver is provided to receive the sensor data wirelessly from the network and the server coupled to the network. Thus, by means of the system according to the invention, an indirect wireless connection can be established between the sensor unit and the receiving unit with the interposition of the server and the network. Compared to a conventional direct radio connection, this offers the advantage that a larger and more reliable coverage is made possible. Such a direct radio link would be prone to failure especially in long trains, in tunnels and mountainous routes. According to embodiments of the invention, the connection to the network can be made separately on the one hand between the sensor unit and the network and on the other hand between the receiving unit and the network wirelessly. This allows for the use of the infrastructure and coverage of the network, especially the Internet.
    By arranging the sensor unit in the rear tension part, a large part of the main air line can be monitored. Preferably, the sensor unit is arranged on the last carriage, whereby the entire main air line can be monitored. This arrangement is based on the finding that due to the serial interconnection of the main air line, the entire main air line can be monitored when the sensor unit is arranged at the end of the main air line. Thus, only a single sensor unit is needed to reliably and inexpensively monitor the entire main air line.
    Advantageously, the transmitter has a transmission modem for establishing a wireless connection to the Internet, and the transmission modem is provided for transmitting the sensor data according to the TCP / IP protocol family (Transmission Control Protocol / Internet Protocol) via the Internet to the server.
    Advantageously, the receiver has a receiving modem for establishing a wireless connection with the Internet, and the receiving modem is provided for receiving the sensor data according to the TCP / IP protocol family via the Internet from the server.
    By using the TCP / IP protocol family, a secure and reliable data connection between the sensor unit and the receiving unit can be made via the Internet.
    According to a further advantageous embodiment, the transmitter and / or the receiver are provided to establish a wireless connection to the Internet via a mobile network.
    According to this advantageous embodiment, the entire network coverage and infrastructure of the mobile network can be used in an efficient and cost-effective manner. For example, the mobile network in Switzerland reaches a network coverage of 100% of all railway lines, so that a permanent and secure connection between the sensor unit and the receiving unit is guaranteed.
    In general, according to embodiments of the invention, all mobile radio networks can be used which have a corresponding network coverage and permit data transmission. In particular, according to embodiments of the invention, mobile radio networks according to the 2G, 3G and 4G standard including future generations can be used.
    According to a further advantageous embodiment, the transmitter and / or the receiver are provided to establish a wireless connection to the Internet via a wireless local area network, in particular via a network according to the WLAN standard IEEE 802.11.
    This is a cost effective and reliable alternative, provided that a cover, e.g. with WLAN IEEE 802.11 exists.
    According to a further advantageous embodiment, the sensor data comprise the measured air pressure in the main air line, the time of the measurement, the local position of the measurement and the speed of the rail vehicle at the time of the measurement.
    The joint collection and transmission of this data gives the driver a comprehensive picture and can be particularly helpful in the investigation of accidents and incidents.
    Advantageously, the sensor unit has a Global Positioning System (GPS) module for determining the speed and the local position.
    This is a simple and efficient way to capture speed and location.
    According to a further advantageous embodiment, the server, the sensor unit and / or the receiving unit are provided for storing and / or evaluating the sensor data.
    The storage of the sensor data is helpful in particular for the subsequent elucidation of faults, damage and accidents. The evaluation of the sensor data, in particular in real time, allows an immediate intervention in the current operation. Thus, for example, in the case of a drop in air pressure in the main air line, a warning / a warning signal can be sent to the train driver.
    Advantageously, the receiving unit is communicatively coupled to a control unit of the leading vehicle and the control unit is designed to prevent starting of the rail vehicle as long as the air pressure in the main air line is outside a prescribable standard range.
    As a result, damage to the brake system can be prevented in a simple and efficient manner, resulting from the approach with not fully released brakes.
    According to a further aspect of the invention, a sensor unit for a system for brake pressure monitoring of an automatic air brake of a rail vehicle is provided. The sensor unit comprises a pressure sensor for measuring the air pressure in the main air line of the air brake and a transmitter for wireless transmission of sensor data of the pressure sensor via a network, in particular via the Internet, to a server coupled to the network. The sensor unit is provided for attachment to the main air line of a car, in particular to the main air line of the last car. For this purpose, the sensor unit is preferably designed as a portable sensor unit, which can be fastened to a coupling point of the main air line of the car of the rail vehicle.
    Such a portable sensor unit allows the maneuvering staff to attach the sensor unit after assembling a train composition on the respective last car. This is a very cost effective and efficient solution because not every car needs to be equipped with a sensor unit.
    Another aspect of the invention relates to a receiving unit for brake pressure monitoring of an automatic air brake of a rail vehicle. The receiving unit has a receiver for wirelessly receiving the sensor data from the server and an output device, in particular a display device, for outputting the received sensor data to the driver of the rail vehicle. The receiving unit is preferably a portable electronic device, in particular a mobile phone, a tablet or a laptop.
    This is also a very cost effective and efficient solution, since no stationary installations are required in the guide vans.
    Another aspect relates to a computer program product for a receiving unit according to the above aspect and a server of an above system.
    Another aspect of the invention relates to a method for brake pressure monitoring of an automatic air brake of a rail vehicle of the type mentioned. The method comprises the steps:
    Measuring the air pressure in the main air line of the compressed air brake by means of a pressure sensor of a sensor unit; Sending the sensor data of the pressure sensor from the sensor unit via a network, in particular via the Internet, to a server coupled to the network;
    Receiving the sensor data over the network from the server by means of a receiving unit and
    Outputting, in particular displaying, the received sensor data by means of an output device of the receiving unit to the driver of the rail vehicle.
    Further embodiments, advantages and applications of the invention will become apparent from the further dependent claims and from the following description with reference to FIGS.

    Way (s) for carrying out the invention Fig. 1 shows a system 100 for brake pressure monitoring of an automatic air brake 10 of a rail vehicle 11. The rail vehicle 11 is designed as a freight train in the embodiment according to FIG. The automatic air brake 10 has a main air line 12. The main air duct 12 extends as a serial continuous compressed air connection from a leader vehicle 13 to a plurality of carriages 14 attached or coupled to the leader vehicle 13. Such an automatic air brake is a standard brake on railroads. The main air lines 12 of the individual carriages 14 and of the leading vehicle 13 have coupling points 15, at which the respective main air line 12 of the respective carriage 14 or of the leading vehicle 13 can be connected to the main air line 12 of an adjacent carriage 14. Especially in freight trains train compositions are changed very often and again and again new cars switched on and off.
    The system 100 has a sensor unit 20, which is provided for measuring the air pressure in the main air line 12. The sensor unit 20 is designed as a mobile, portable unit and can be attached to one of the coupling points 15 of the main air line 12 as needed. Preferably, the sensor unit 20 is attached to the last carriage 14e of the respective train composition, as shown in FIG.
    The leader vehicle 13 has a driver brake valve by means of which the driver can control the air pressure in the main air line 12. In the respective car 14 and the leading vehicle 13 are local braking devices 16 which are coupled to the main air line 12. The local braking devices 16 are controlled by the main air line pressure.
    Fig. 2 shows the sensor unit 20 in more detail. The sensor unit 20 has a pressure sensor 21 for measuring the air pressure in the main air line 12 of the compressed-air brake 10. In addition, the sensor unit 20 has a transmitter 22 for wireless data transmission of sensor data. The transmitter 22 comprises a transmission modem 22a and an antenna 22b. The sensor unit 20 also has a connection piece 23, by means of which the pressure sensor 21 can be connected to the main air line 12 for pressure measurement. Preferably, the connecting piece 23 can be connected to the coupling points 15 of the main air line 12. The sensor unit 20, according to preferred embodiments, further comprises a processor 24, a data memory 25, a Global Positioning System (GPS) module 26 and a display 27. The individual components of the sensor unit 20 are coupled by means of a bus system 29. In operation, the sensor unit 20 measures the air pressure in the main air line 12 by means of the pressure sensor 21 and sends it to a server 40 coupled to the Internet 30. For this purpose, the transmission modem 22a establishes a wireless connection to the Internet 30 via the antenna 22b and transmits the sensor data according to the TCP / IP protocol family via the Internet to the server 40. In general, however, other networks than the Internet could be used, provided that the appropriate network coverage is available.
    In addition to the measured air pressure in the main air line 12, the sensor data may in particular also include the time of the measurement, the local position of the measurement and the speed of the rail vehicle 11 at the time of the measurement. The location of the measurement and the speed are determined by the GPS module 26. The server 40 is provided for receiving the sensor data and for forwarding the sensor data to a receiving unit 50. In addition, the server 40 is provided for evaluating the sensor data and for storing the sensor data in a memory unit 41.
    The receiving unit 50 is arranged according to FIG. 1 in the driver's cab of the guide vehicle 13 and shown in detail in FIG. It comprises a receiver 51 for receiving the sensor data wirelessly from the server 40. The receiver 51 has a receiving modem 51a and an antenna 51b and in operation establishes a wireless data connection with the Internet 30 via the antenna 51b and receives the sensor data according to the TCP / IP protocol family via the Internet connection from the server 40. The receiving unit 50 also has as an output device on an optical display device 52, eg an electronic display. On the display device 52, the train sensor, the received sensor data, in particular the air pressure represented. This allows the driver to reliably monitor the air pressure or brake pressure in the main air line 12. Further, the receiving unit 50 as a sound output device on a speaker 53. Finally, the receiving unit 50 has a processor 54, a memory unit 55 and a bus system 56. In the memory unit 55, a computer program product may be stored, which has program code sections that can be read by the receiving unit 50. The computer program product may e.g. an application program to be applied to the receiving unit 50, e.g. a driver's laptop or smartphone, can be loaded and then controls communication with the server 40, receiving the sensor data, and outputting the sensor data.
    The arrangement of the sensor unit 20 on the last carriage 14e, as shown in Fig. 1, the air pressure in the entire air brake 10 with a single sensor unit 20 can be detected safely and reliably, since a leak and a related compressed air drop in the front carriage 14th also affects the air pressure in the main air line 12 in the traction behind it and thus on the last car 14e is measurable.
    In particular, when releasing the brake after a braking operation, the train driver can check before starting by means of the receiving unit 50, if really all the brake units 16 of the entire train composition including the brake unit 16 of the last car 14e are solved.
    The connection of the sensor unit 20 and the receiving unit 50 to the Internet 30 can take place in accordance with a preferred embodiment via a mobile radio network. With the appropriate network coverage, this can in principle be any available mobile radio network. In particular, the mobile radio standards 2G, 3G and 4G as well as all future generations and variations are suitable which allow data transmission.
    According to another advantageous embodiment of the invention, the wireless connection of the sensor unit 20 and the receiving unit 50 to the Internet via a wireless local area network. This can e.g. a network according to the WLAN standard IEEE 802.11. However, this requires a corresponding coverage along the respective train route.
    According to advantageous embodiments of the invention, the connection to the Internet 30 can also take place in combined form both via a wireless local area network and via a mobile radio network. For this purpose, the transmitting modem 22a and the receiving modem 51a can be configured such that they preferably connect to the Internet via a wireless local area network, provided that a corresponding WLAN network coverage is available. As soon as such a WLAN network coverage is no longer available, the transmitting modem 22a and the receiving modem 51a automatically connect to the mobile radio network. This enables cost-effective, efficient and reliable operation.
    According to advantageous embodiments of the invention, the server 40, the sensor unit 20 and the receiving unit 50 are provided for storing and / or evaluating the sensor data. The storage of sensor data allows in particular the elucidation of disturbances and accidents. The evaluation of the sensor data can be carried out in particular in real time and makes it possible to issue warnings to the driver in the event of faults. Thus, e.g. the train driver is warned visually via the display unit 52 or acoustically via the loudspeaker 53 of the receiving unit 50 when the air pressure in the main air line 12 drops below a normal range.
    The receiving unit 50 is communicatively coupled according to a preferred embodiment of the invention according to FIG. 1 with a control unit 60 of the leading vehicle. This may also be wireless over a radio link, e.g. by means of near-field communication, or via a wired connection. The control unit 60 is designed to prevent starting of the rail vehicle 11, as long as the air pressure in the main air line 12 is below a predefinable standard range. This will be explained in more detail with reference to FIG. 4.
    Fig. 4 shows schematically a more detailed representation of the individual components of the automatic air brake 10 according to embodiments of the invention. The automatic air brake 10 includes a compressor 401 that generates the pressure for the air brake 10. During operation, the compressor 401 presses compressed air into a main air reservoir 402. From the main air reservoir 402, the compressed air generated by the compressor 401 passes through the driver brake valve 17 into the main air line 12. The driver can control the main air line pressure in the main air line 12 by means of the driver brake valve 17. The brake units 16 of the individual carriages 14 and the leading vehicle 13 have

    [1]
    in each case at least one control valve 403, an auxiliary air reservoir 404 and a brake cylinder 405. The air brake 10 is ready (released) when the air pressure (brake pressure) in the main air line 12 is within a normal range. The standard operating pressure is usually 5 bar. Then all the auxiliary air tank 404 are filled. By operating the driver's brake valve 17, the driver can lower the air pressure in the main air line 12, whereby the control valves 403 direct the compressed air from the auxiliary air tanks 404 in the brake cylinder 405 and thus brake the rail vehicle. Lowering the air pressure to 3.5 bar usually corresponds to full braking. After a braking operation, the train driver can release the brake units 16 by raising the air pressure in the main air line 12 back to the control operating pressure of 5 bar via the driver brake valve 17. In order to prevent starting before this control operating pressure is reached along the entire length of the main air line 12 and thus all brake cylinders 405 are released, the control unit 60 monitors the air pressure (brake pressure) measured by the sensor unit 20 and transmitted to the receiving unit 50 and blocks or prevents it a start of the rail vehicle, as long as the control operating pressure is not reached. For this purpose, the control unit 60 may be coupled to a drive electronics 61 of the rail vehicle 11, for example. Additionally or alternatively, the train driver can be informed via an acoustic or optical signal that the control operating pressure is reached in all cars and thus also in the last car 14e and thus a safe / harmless start is possible. Fig. 5 shows a flow chart of a method for brake pressure monitoring of an automatic air brake of a rail vehicle according to embodiments of the invention. In a step 510, the air pressure in the main air line (HLL) 12 is measured by means of the sensor unit 20. In a step 520, the measured air pressure and other sensor data such as the time, position and speed of the rail vehicle 11 are stored in the data memory 25 of the sensor unit 20. In a step 530, the measured sensor data is sent / transmitted from the sensor unit 20 to the server 40. In a step 540, the sensor data is received by the server 40. In a step 550, the received sensor data is stored in the storage unit 41 of the server 40. In parallel, the sensor data from the server 40 are evaluated in a step 542 and it is checked in a step 544 whether the air pressure in the main air line 12 falls below the control operating pressure. In the event of an abnormal drop in air pressure, the server 40 sends a warning to the receiving unit 50 in a step 546. In a step 560, the server 40 sends the sensor data to the receiving unit 50. In a step 570, the sensor data and possibly the warning are received by the receiving unit 50 receive. In a step 580, the sensor data and possibly the warning are displayed on the display unit 52. Finally, in a step 590, the sensor data and possibly the warning are stored in the memory unit 55 of the receiving unit 50. Alternatively or additionally, the evaluation can also take place in the sensor unit 20 and / or the receiving unit 50.
