Definitions
- the invention relates to a method for carrying out a requested emergency stop for a train, so that the train comes to a stop at a suitable point in the route traveled by the train.
- train refers here to a combination of several rail vehicles or a single rail vehicle.
- This request is made, for example, by the passenger in a passenger car operating a lever referred to there as an “EMERGENCY BRAKE” in order to trigger the request.
- a request that is triggered by control technology internal to the rail vehicle. This request occurs, for example, in response to a detected technical fault in the rail vehicle.
- the driver initiates the emergency stop and, if necessary, lifts the braking that has already been triggered automatically. again or it ignores the request - for example if there is a noticeable misuse of the "emergency brake" lever or if there is a detectable control technology error.
- a suitable location for the emergency stop is selected by the driver, who, depending on the situation, selects a suitable location for the emergency stop on the route and brings the rail vehicle to a stop there.
- the emergency stop may not take place at any point on the route traveled by the rail vehicle; for example, it is not permitted on a bridge or in a tunnel due to safety requirements and access restrictions. unfavorable.
- the invention relates to a method for executing a requested emergency stop for a train in order to bring the train to a stop at a suitable point on the route traveled by the train.
- the route to be traveled is determined in terms of suitable places to stop or. Stopping zones analyzed that are suitable for stopping the train in the event of an emergency stop. These locations are defined as emergency stop zones.
- emergency stop prevention zones are defined in which the train is not allowed to stop in the event of an emergency stop.
- the emergency stop prevention zones include, for example, bridges, tunnels, areas of the route that are difficult to access, etc.
- the respective zones are preferably determined with the help of a highly accurate electronic geographical map in order to identify the zones (emergency stop zones and/or emergency stop prevention zones) using geographical coordinates or To define position information precisely.
- the zones are saved as a list on board the train for automated use before the start of the journey. filed.
- the list is preferably stored in a vehicle control system of the train and is therefore available on the train side.
- only the emergency stop prevention zones on board the train are stored in the list; accordingly, remaining route sections are considered suitable emergency stop zones that can be used for this purpose.
- the list is thus shortened and can be queried quickly in an automated manner, so that the method according to the invention can be carried out quickly.
- a request for an emergency stop is recorded and analyzed without the involvement of the driver.
- the request is preferably recorded, evaluated and processed by an automatic emergency stop function provided for this purpose.
- the request for an emergency stop is made, as described above, for example by a passenger or by a train or Rail vehicle internal control technology triggered.
- the request for an emergency stop is optionally communicated to the driver.
- the driver then has the option of “resetting” the emergency stop request or manually postponing the execution of the emergency stop or completely suppressing it depending on the situation.
- a fixed operations control center known as the “land side” is automatically notified of the emergency stop request.
- This automated notification is preferably carried out with the help of the emergency stop function, which automatically generates corresponding information when the emergency stop request arrives and transmits it to the operations control center.
- a cause of the requested emergency stop (e.g. message “fire on board” or “emergency brake lever activated”, etc.) transmitted, and/or
- - information is transmitted about a train section (car) in which the emergency stop request was triggered by a passenger.
- the automated notification makes it possible on land to set a rescue chain in motion, to take appropriate measures to deal with the emergency stop of the train, to subsequently analyze the emergency stop and/or to notify maintenance staff, etc.
- the automated notification of the landside is carried out via a secure and highly available data connection, which in particular has a the necessary safety level in accordance with the European standard EN 50128 or EN 50657 and EN 50159 complied with.
- the position of the train is determined automatically.
- the position is determined primarily by the train and therefore independently of the land side. This enables accelerated and self-sufficient processing of the method according to the invention.
- a satellite-supported positioning system is used to determine the position (e.g. a GPS receiver, a Galileo receiver, etc.).
- the train's position is continuously determined during the entire journey, so that the respective current position is available at all times.
- the position determination is replaced from the time of the disruption by a path detection system that is installed in the train and is based on a determination of wheel revolutions.
- the installation location of the antenna used for satellite reception in the train is saved in the train's control system.
- total length, installation location it is possible to determine the position of a front and a rear end of the train. In a preferred further training the information
- Minimum zone length required for the emergency stop is used to find a suitable location along the route for the emergency stop.
- the installation location or the position of the satellite antenna in the train is calculated based on the train composition information stored in the control system.
- a fourth step the distance of the train to the next possible emergency stop is calculated.
- the control technology calculates the distance from the train to the next possible area for an emergency stop.
- a fifth step braking on the train with appropriate braking parameters is initiated automatically and in this way. carried out so that the nearest emergency stop zone is reached and the entire train comes to a standstill in it.
- an automatic emergency stop function provided for this purpose continuously compares the current train position with the stored location information of the zones.
- the emergency stop function evaluates whether an emergency stop can take place at the current time:
- the emergency stop function prevents emergency braking to stop the train immediately.
- the automatic emergency stop function initiates the emergency braking only then and in such a way that the end of the train passes through an emergency stop prevention zone in the optimal time and comes to a stop behind the emergency stop prevention zone in the emergency stop zone as quickly as possible.
- the emergency stop function uses the expected braking distance to calculate the information as to whether the start of the train will come to a standstill before the next emergency stop prevention zone or not.
- the emergency braking is triggered immediately. If this is not the case, the emergency stop function delays the emergency braking in such a way that the rear end of the train comes to a standstill directly behind the emergency stop prevention zone in the optimal time.
- the expected braking distance is continuously determined by the automatic emergency stop function based on train data (train length, braking hundredths, mass, current wheel/rail friction values, weather conditions). relationships, etc. ) and the current train speed are calculated.
- the emergency braking is triggered by transmitting appropriate braking commands to the train's braking and drive equipment.
- the driver has the option at any time to cancel an automatic emergency stop or to trigger an emergency stop manually by using controls on a driver's desk.
- a train is brought to a standstill at an optimal location automatically and without manual intervention by the driver when an emergency stop is requested.
- the present invention information required for the emergency stop is determined without loss of time and made available to an operations control center, which can then promptly transmit an exact location for the emergency stop to be carried out.
- the present invention also enables optional intervention by the driver and/or the land side when executing the emergency stop.
- the present invention increases both precision and reproducibility of emergency braking.
- the present invention reduces reaction times and if necessary. flawed human influences.
