    Automatic brake monitoring
    The invention relates to a device for automatic monitoring and control of pneumatic brake systems of vehicles, as well as methods for monitoring the pneumatic brake systems of parked and towing vehicles with this device.
    Especially in railway operations and trucks compressed air brakes are used as service and / or parking brakes. In this case, compressed air is used both as an energy source for pressing the brake pads on the running surface or brake discs of wheels, as well as to control the braking process. In principle, such an air brake consists of a system of compressed air tanks, brake cylinders, controls and compressed air lines on each vehicle, which are connected to each other in the composition of a train at the coupling points.
    All vehicles of a train have a continuous, interconnected main air line (HLL) and additionally with passenger coaches a continuous main container air line (HBL). A compressor on the locomotive supplies a main air reservoir with compressed air, which provides the necessary compressed air for the operation of the brake, as well as for all pneumatic control devices and consumers of the locomotive and the train. The supply of the train is ensured in passenger cars on the continuous main tank air line HBLL and / or continuous main air line HLL (as in a freight train). The control of the "self-acting indirect air brake" of all connected cars is controlled via the HLL. This will be from the HBL
    2 49697 Ag / Fl
    OeBB Technical Services GmbH
    Main air line (HLL) supplied via the driver's brake valve or the HL-control unit on the locomotive with compressed air, which usually has a pressure of 5bar (the control pressure). The main air line (HLL) is next to the
    Main tank line (HBL) as an energy supplier and for controlling or regulating the brake.
    Each vehicle also has an auxiliary air reservoir, which is constantly refilled via a check valve from the main air line (HLL) and / or main reservoir air line (HBL), as well as air-operated brake cylinders and brake pads on the wheels or disc brakes in the wheel or on the axle shaft. The principal control element for the brake system is the "driver's brake valve" on the locomotive or locomotive.
    Such a compressed air brake can be performed either directly-acting or indirectly-acting.
    The indirectly acting compressed air brake is released (inactive) when all auxiliary air tanks are filled and the main operating pressure prevails in the main air line. If the pressure in the main air line is lowered, then the control valves direct the compressed air by means of pressure booster from the auxiliary air tanks in the brake cylinder (so-called C-pressure) on a brake linkage press the brake pads on the wheels or brake discs or actuate the brake calipers of the disc brakes. The brake system is dimensioned so that when lowering the pressure of the main air line to about 3.5 bar (full braking) and a completely empty main air line (0 bar for a quick, emergency or emergency braking) in the brake cylinders, the appropriate pressure depending on Braking mode is pending. After a braking operation, the brake is released by refilling the main air line to the normal operating pressure of 5 bar. As a result, the control valves return to their initial position, the air from the brake cylinders escapes into the open air, the brake pads release, and the auxiliary air reservoirs are filled.
    The direct-acting air brake acts only on the traction unit. In the braking position, the responsible brake valve is de-energized and allows compressed air directly from the main reservoir line (HBL) via a pressure reducing valve and a double check valve to the two pressure intensifiers (eg at LR * * * * φ φ * * * ψ * * * * * * * »Λ φ · ># •» · * «» · 3 49697 Ag / Fl
    OeBB Technische Services GmbH 1016/1116 "KR-5'1). With the release command, the responsible release valve is activated and this line is vented again. HBL supplies these brake systems via a non-return valve, with compressed air for the brake being stored by a reservoir per bogie. 5
    In addition, rail vehicles and trucks often have a parking brake, which is designed in the form of a spring brake. In this case, a braking effect is achieved by spring pressure in the brake cylinder of the parking brake. This braking effect can be canceled by air pressure or mechanical io unlocking in the spring brake cylinder again.
    When releasing the spring brake, the release valve of the spring-loaded exchange valve is activated. As a result, compressed air flows from the Hauptbehäiterleitung HBL via a pressure reducing valve in the Federspeicheris brake cylinder and triggers the spring brake by canceling the spring pressure.
    If the spring brakes applied again, the spring brake cylinder 20 are vented again by driving the release valve on Federspeicherwechselventil. By the spring force the spring brakes are set again. Again, in the spring brake of the HBL via a check valve supplies this system and stored in a reservoir compressed air for releasing the brakes. A major problem in the operation of vehicles that are equipped with such pneumatic braking systems, is that on the one hand when parked vehicles on the application of the parking brake is forgotten, or this is defective, which can lead to unrolling. Another problem is that when towing, unintentional application of the parking brake 30 can happen, thereby damaging the wheels and the brake itself. The parking brake is released during towing, but not permanently monitored. A sudden application of a pneumatic spring-loaded brake can also be caused, for example, by pressure loss in the spring-loaded system (hose breakage, hose breakage, hose breakage, hose breakage, hose breakage, hose breakage, etc.). * ι · B »« · * 4 49697 Ag / Fl
    OeBB Technical Services GmbH leaking points) or by human error (accidentally shut off drag cock) take place, which is generally not recognized.
    It is therefore an object of the invention to provide an automatic monitoring and control device of the pneumatic brake systems of vehicles, which avoids the above disadvantages. In particular, the state of the parking brake should be checked and controlled in order to prevent unintentional application of the parking brake in the case of the parked vehicle unrolling, and in towing.
    This object is achieved in that the device comprises a, the air pressure of the brake systems by pressure sensors monitoring pneumatic module and an associated, one or more braking systems-driving control module, which is designed to receive position data of the vehicle.
    By receiving position data (for example GPS data), a reliable detection of a change in position can take place, in particular in the case of monitoring the parked vehicle, and the corresponding steps are initiated. This may include both accidental unrolling and detection of a towing operation. For this task, a Beschieunigungssensor be provided, which detects entrolling even if the GPS reception is not possible, for example, in a tunnel or at a covered or underground station.
    The monitored brake systems may in particular be an air pressure brake (service brake) and a spring brake (parking brake), and the pneumatic module may absorb the pressure of these brake systems and the pressure of a main air line by pressure sensors. Furthermore, according to the invention, the control module can comprise a signal line activating the spring accumulator control in order to be able to directly control the state of the spring-loaded brake.

    The pneumatic module may further include, the Hauptiuftleitung entlüftendes, controllable by the control module emergency brake valve to perform in case of danger (unrolling, etc.) an immediate emergency braking can.
    It may further be provided according to the invention that the device comprises a deactivating stopcock. The control module can be designed in particular as a programmable logic controller. This can have both analog and digital inputs and outputs.
    According to the invention, the device may comprise or be connectable to an acceleration sensor or motion sensor as well as an electronic compass in order to be able to detect a change in position even in the event that there is no GPS data. The control module can advantageously be connected or connectable to a message system on the vehicle.
    In particular, it is provided that the control module comprises a CPU box which has at least one means for data transmission, such as GSM module, USB connection, network connection, RS232 interface, RS485 interface, or bus interface. The CPU box or control module may include at least one antenna port for connection to a GPS and / or GSM antenna.
    The mentioned bus interface parts of the CPU box can be designed, in particular, for connection to an external EDI unit. But it is also a direct connection of the control module with an external data transmission unit via another means for data transmission part of the invention. The CPU box can also be used to connect to external systems such as chassis diagnostic and monitoring (FDT) systems.
    In particular, it is provided that the control module of the device may include its own GSM module which can send SMS for warning and information purposes and receive commands by SMS. Of course, the GSM module also other mobile communication standards such as HSCSD, GPRS, UMTS, etc. • ············· # 6 49697 Ag / Fl
    OeBB Technische Services GmbH for this purpose, and instead of the SMS, the message can also be sent by other means, such as an email.
    Furthermore, the invention also encompasses a method for monitoring and controlling the brake systems for checking the shutdown of parked vehicles with a device according to the invention, the method comprising the following steps: a. After switching off the locomotive control permanent monitoring of the battery voltage, the brake systems as well as receiving and monitoring of position data; b. when switching off the battery circuits automatic bleeding for 3 seconds of the main air line and, if after this period the spring brake is not activated, activating the spring brake; c. when unrolling immediate emergency braking by venting the main air line; d. If braking systems are not activated after a predefined time after switching off the locomotive control, immediate emergency braking takes place by venting the main air line.
    After an emergency stop, depending on the cause of the event, an alarm system or information system with all important operating data or when the vehicle is unrolled, a warning system can be activated by sending e-mails or SMS to the affected locations, or an alarm chain can be triggered. The unrolling of the vehicle can be detected by monitoring position data, for example by means of GPS, and / or by an acceleration or movement sensor. When unrolling an optical warning message on the vehicle by driving the headlights, as well as an audible warning by the Ansteuem the Makrophon horns are also issued.
    In the method according to the invention, it can further be provided that emergency braking takes place by venting the main air line when a brake system, in particular the spring-loaded brake (parking brake) is not applied 60 seconds after the locomotive control has been switched off. • ♦ · · «49697 Ag / Fl
    OeBB Technical Services GmbH
    Finally, the invention comprises a method for monitoring and controlling the braking systems of vehicles in towing with a device according to the invention, in which after a brake test the air pressure of the pneumatic brake systems is permanently monitored and emergency braking is initiated by venting the main air line, if after a predefined period at least one of the brake systems is activated or not completely solved.
    In this inventive method for securing the towing operation, the initiation of emergency braking can then take place if 60 seconds after the brake test activated or not completely dissolved brake systems are detected.
    A part of the invention is that in an emergency braking in towing, by an operational event (SIFA or train or emergency brake on a passenger train, etc.) of the towing command is not reset, so that the spring brakes can not create unwanted automatically. Furthermore, in the tunnel area one kilometer before and one kilometer after the tunnel, the control of the emergency brake valve is to be prevented by the control module, wherein in case of an event the system is to be maintained as long as the GSM connection exists.
    At the end of the towing can be done by a targeted action of the engine driver, a reduction in the pressure of the main air line below 2.8 bar, a reset of the drag command and thereby a HL-controlled application of the spring brake, even by venting the HL at the parked vehicle {open the Shut-off valve of the HLL) or by pressing the spring-loaded button on the long carrier, the drag command can be reset and thus the application of the spring-loaded brake can be triggered. After resetting the towing command, the connection to the driver's mobile phone should be automatically terminated after a defined time
    49697 Ag / Fl OeBB Technical Services GmbH
    Both in the method according to the invention for checking the control and in the method according to the invention for securing during towing operation, the battery voltage can be monitored and a warning message can be sent when a defined limit value is reached, one of the abovementioned means for data transmission can be used. When a defined limit value is exceeded, all consumers (except AFU) are switched off. Irrespective of this, in both methods, data can be regularly sent to a server by means of a GPRS connection and, in the case of certain events, an SMS message, e-mail or the like can be automatically sent to the driver and to a server.
    Further features of the invention are described in the description, the claims and the figures.

The traction unit and the wagon have, inter alia, the pneumatic brake systems 2 in the form of a parking brake (spring brake 38 with spring brake cylinder 26) and a service brake ( Air brake 39 with air brake cylinder 25). These braking systems are controlled by control systems (Druckiuftbremssteuerung 8, spring brake control 9). Furthermore, the continuous UIC line 24 and the main air line 10 and the main container line 13 can be seen. The UIC cable is a standard interconnecting cable that exchanges data and commands between the locomotives and the cars of a train

This includes a pneumatic module 5 and a control module 6. The pneumatic module 5 includes pressure sensors 4 for measuring the pressure of the main air line 10, the air brake cylinder 25 and the spring brake cylinder 26. Furthermore, a stopcock 12 and an emergency brake valve 11 is provided in the pneumatic module, which vent the main air line 10 can. The pneumatic module 5 is connected to the control module 6. The heart of the system is the CPU box 40 in the control module 6, where 42 data of the pressure sensors 4 or digital information 44 such as "battery circuits off" or "locomotive control active" are read through digital and analog inputs. From

    OeBB Technical Services GmbH this CPÜ box 40 GPS signals are to be received, whereby position data 7 are provided for the evaluation of the software available, For this purpose, the CPU box 40 is equipped with antenna connectors 17 for GSM or GPS antennas 15. Further, an acceleration sensor (motion sensor 36) and an electronic compass 43 are also installed in this CPU box to detect a vehicle motion should no GPS signal be received. Optionally, signals from the locomotive controller should also be read in here via galvanically isolated, free analog inputs in order to ensure fast locating of e.g. allow for volatile errors on the vehicle. For transmission of the data, the CPU-Box has data transfer means 18 in the form of USB port, network connection, RS232 and RS485 interfaces. It is further a reporting system 14 (in the form of acoustic and optical signals) connected and created the ability to connect a terminal 19 to the device. To control the
    Federspeicherwechselventils 35 a signal line 41 is provided.
    The bus interface 16 in the form of a CAN bus interface and a

    FIG. 3 shows an exemplary embodiment of a device 1 according to the invention in the form of an automatic spring-loaded monitoring, which is connected via the bus interface 16 to a further diagnosis and monitoring system 20. When connecting several systems, e.g. the FDÜ (chassis diagnosis and monitoring) should be able to take over the EDI for these systems. Furthermore, interference avoidance or information from other systems, which are connected via network or bus system, to be transmitted via dial-up for these systems. If, among other things, a screen output is provided via a monitor 21, e.g. Fault messages that are received over the remote locomotive from the towed locomotive can be viewed on this monitor.

Both traction vehicles have an inventive device 1 for monitoring and controlling the brake systems 2, which receives position data 7 from a GPS system 33 - it may be one or more GPS satellites. Furthermore, the traction vehicles communicate with each other via mobile radio messages 27. The train driver can thus connect directly to the other device 1 by means of a mobile phone. In particular, the connection can be made automatically on departure to the control module of the occupied traction vehicle. In case of an event information with all necessary data is simultaneously transmitted to the driver as SMS and io via GPRS to a server.

Data is regularly sent by the traction vehicle 22 in the form of GPRS messages via a GPRS data link 28 to a server 30 on the Internet, and 16 from the server, for example, via a Netzwerkvertoindung 29 to workstation 31 for evaluation, or in the form of remedies for the train driver a mobile device 32, eg a smartphone, forwarded. This allows the analysis and evaluation of the data by own software (for example for braking data, acceleration, speed, location over coordinates, etc.). 20
    Fig. 6 shows an embodiment of a method according to the invention using the example of an active locomotive control by activated cab or remote control operation or radio remote control, in which during a position change (while driving), the spring pressure is monitored. It is shown how a fault, such as a line break when reading the battery circuits, is reported 25. If the signal for disconnected battery circuits can be detected by e.g. If a line break is not read in, a fault message is emitted by the flashing light and buzzer on the traction unit when the locomotive control is activated. In ferry mode with active locomotive control of the spring pressure 30 is monitored, with a pressure loss emergency brake is triggered. In the tunnel area as well as at standstill the AFÜ emergency brake valve is blocked.
    When switching off the locomotive control, the monitoring system should become active. This is indicated by the step 1.1 at the end of the flowchart of FIG. 6. 12
    49697 Ag / Fl OeBB Technical Services GmbH
    Fig. 7a shows the inventive method in the case of a deactivated locomotive control. If only the locomotive control is deactivated and the battery circuits remain switched on, it should also be checked here on the vehicles whether the brakes are applied or the spring-applied brakes are set. If the brakes are not applied (direct brake or spring-loaded brake), the vehicle should be braked after 60 seconds by venting the HLL. Towing in this state should be prevented automatically by the activated AFÜ emergency brake valve.
    If the battery main switch is also switched off or the battery circuits switched off, the HLL is to be vented for a predefined period of time, for example 3 seconds, and the vehicle is thus braked in a targeted manner. Subsequently, the spring brakes are to be created automatically. With parked vehicles, the battery voltage is constantly monitored and a message is sent when a defined voltage is reached. If the battery voltage reaches a critical value (eg, 18V at 24V battery voltage) all consumers (except the AFU itself) should be switched off.
    When switching off the battery circuits, the HL is vented after three seconds and then set the spring brake. If there is a change in position, we set the diagnostics unroll in the controller.
    When the vehicle is parked, the brakes should be applied automatically by targeted venting of the main air line or should the application of the spring brakes have been forgotten, the spring brakes should be set automatically 3 seconds after the main switch is switched off. This monitoring system should unroll as much as possible.
    In addition, it should be possible to tap signals via free analog inputs in order to ensure fast location of e.g. allow for volatile errors on the vehicle. These signals should be recorded as a function of time and 13
    49697 Ag / Fl OeBB Technical Services GmbH via DFU to be sent to a sender. From this server these data should be available to the respective service technicians for evaluation and analysis.
    Fig. 7b shows the method according to the invention in the case of alarming when 5 unrolling and the automatic braking of the vehicle in this case. When unrolling a vehicle, the HL is automatically vented and triggered an alarm chain. Via GPRS packets, the alarm message with details of the coordinates is sent to the server and at the same time an audible and visual warning message is given to the vehicle. This is done by flashing the headlights and io continuous tone as long as the vehicle moves from at least two horns for 20 seconds, where after the rest of the vehicle, the remaining time of 20 seconds is emitted by an interval tone of one second pulse pause time the signal. Mechanically released spring-loaded brakes are automatically unlocked by releasing a release command for the time being and, when> 4.5 bar is reached, the spring-loaded brake cylinders are again vented by the setting command.
    Fig. 8a shows the inventive method for automatic 2o brake monitoring before a towing. If the vehicle is coupled, the spring-loaded brakes should be released automatically after bleeding the brake cylinder in the course of a brake test and subsequent dissolution process. The train driver should have the ability to establish a connection to the control module of the AFÜ by dialing the respective phone number of the device by mobile phone. If the spring-loaded brakes do not release within 60 seconds (locked tractor cock or severe leaks in the spring-loaded system), emergency braking should be initiated by venting the HLL. If a connection to the control is established, the train driver should be informed automatically via SMS, so that appropriate measures can be initiated immediately.
    When towing the release or application of the spring brakes should be done automatically. This is not realized in the AFC, as in the vehicles 1216 or 189 (DB), by a purely pneumatic solution, but by the equation. fr «·« 14 49697 Ag / Fl
    OeBB Technische Services GmbH Monitoring of the dynamic processes in the HLL with appropriate sensors and the resulting activation of the spring-loaded changeover valve (release and braking).
    FIG. 8 b shows the method according to the invention for automatic brake monitoring during a downhill run. Monitored during towing is the C-pressure, as well as the spring-loaded brake cylinder pressure. In the tunnel area, an emergency braking initiated by the AFC is prevented one kilometer before and after the tunnel. The message to the engine driver as well as the information about GPRS to the server remain upright.
    Should the spring brakes automatically apply during a towing or braking due to a residual pressure in the brake cylinder (C-pressure> 0.2bar) does not fully trigger emergency braking should be automatically initiated so as to avoid damage to tires and brake units.
    On the long beam, a release operation is to be made possible in the time window of 30 seconds, should the pressure switch for confirming the HL pressure> = 4.9 bar be defective or this pressure can not be achieved. The latter could be possible in a long train, where by means of Füllstoß or Angieichen release could be made possible. Apart from this time window of 30 seconds after a brake test, a release of the spring brakes by means of release button on the longitudinal beam through the AFÜ should be prevented. At the same time, the C-pressure of the brake systems should be monitored in order to ensure complete release of all brakes. While driving, the spring brake cylinder pressure should be constantly monitored. In the event of a pressure loss in the spring accumulator (hose breakage or severe leaks in the spring accumulator system), damage to wheelsets or brake assemblies should be avoided by automatically applying the spring-loaded brakes by initiating emergency braking by venting the HLL. In order to be able to initiate appropriate measures immediately, the train driver must also be informed automatically via SMS,
    If the vehicle is to be parked after a slowdown, the driver should lower the spring brake on the vehicle by lowering the HLL below 3bar. * ····················································································
    49697 Ag / Fl OeBB Technical Services GmbH. The shifter can thus order after shutting off the UIC stopcocks pressing the train driver and uncouple the vehicle.
    It should also be possible to apply the spring-applied brakes via the control elements of the spring-loaded brake on the long carrier. By applying the spring brakes the tow command should be reset automatically and after a defined time the connection to the driver's mobile phone should be terminated.
    Vehicles can also be coupled to a passenger train during towing. Here, even with a pulled emergency brake in hazardous areas such. In the tunnel area, they have the option of bridging them through the NBÜ. This happens because emergency braking of any kind is prevented by the fact that the AFÜ emergency brake valve is switched off 1 kilometer before the tunnel entrance. The AFÜ emergency brake valve is activated 1 km after the exit of the tunnel, if it is triggered by the AFÜ.
    For this reason, the following command may only be reset if at standstill an HL pressure > 3 bar prevails and this is lowered below 2.8 bar. In the tunnel area, the AFÜ emergency brake valve is to be suppressed one kilometer before and after the tunnel in case of an event (for example heavy pressure loss in the spring accumulator due to hose breakage), but as long as GSM reception is possible, the reporting system should be maintained via GPRS on an external server. Subsequently, an emergency braking should be initiated by the AFÜ.
    In the event of a malfunction of the AFÜ, it should be possible to switch off the AFÜ system by shutting off the main air line in front of the AFÜ emergency brake valve and by switching off the electrical system by laying out the AFÜ machine. A fault message by continuous light should signalise the switched-off state. When switching on the locomotive control or in the remote control mode, a redundancy is to be produced by an additional signal, where in case of failure of one of these signals, a fault message by continuous light to signal this state. With this additional signal of the activated locomotive control, errors such as e.g. Broken conductor 16 ·· »♦« ·
    49697 Ag / Fl OeBB Technical Services GmbH are recognized and signaled and displayed accordingly by an error message. For monitoring functions that trigger emergency braking in the event of faults, an acoustic and visual fault message should be emitted by the flashing light and the buzzer. Depending on the function or program step, these fault messages should be automatically reset, whereby the emergency brake valve is closed again. Basically, in the case of faults with flashing light and buzzer, an act is to be set by the driver. The AFC detects faults on the HL pressure switch or HL pressure sensor because it is read in redundantly by the pressure sensor. Within 30 seconds it comes to emergency braking. By flashing the signal lamps and acoustically via buzzer with simultaneous error message "Pressure switch defective" via dial-up or SMS, this fault is displayed. Detected line interruption (less than 2V) of the pressure sensor. In this case, the driver is signaled and signaled by flashing signal lamps and acoustically via buzzer and via a defined fault message "pressure sensor defective" (dial-up or SMS). A further journey is possible here after switching off the AFÜ.
    Due to an error, for example due to voltage carryover, a misinterpretation in the controller could trigger a drag command. A drag command would release the spring brakes and an acute danger of entrapment would exist. This set command to trigger the spring brake should only become active when a pressure drop <3.5 bar is reported by the pressure transducer and then an HL pressure> = 4, 8bar is transmitted by the pressure transmitter but also at> = 4.9 bar from the pressure switch of the controller. If this pressure is only read in analogue or digital mode, emergency braking should be initiated after 30 seconds. A corresponding fault message is output. • *. * · ·· * * * * * * * * * * * * * * * * I t «· β ·· * I * # ·· · · * * 17 49697 Ag / Fl
