Definitions
- the invention relates to a method and a system for controlling sanding of a sanding system of a rail vehicle while it is traveling on a route.
- the invention relates to a rail vehicle and an electronic route map.
- the rail vehicle When operating the vehicle, it must be ensured that sanding is permitted.
- the rail vehicle must therefore be in a permitted area of the route or in an area in which sanding is permitted above a certain speed threshold and its speed exceeds this speed threshold.
- the train driver hereinafter simply referred to as the "driver” must ensure that the sanding does not occur in "prohibited” areas or is used in an unlawful manner. If this does happen, the vehicle driver must report this to an operations control center. This then decides on further measures such as: B. cleaning the rails.
- the method according to the invention is used to control sanding of a sanding system of a rail vehicle while it is traveling on a route.
- the process does not necessarily have to control the sanding system itself with direct commands, but can also control a control unit of the sanding system. be implemented in such a control unit. However, it can also be implemented in a unit between such a control unit and the sanding system and allow or block sanding commands from this control unit to the sanding system.
- the procedure includes the following steps:
- route maps are known. However, route maps are used here which have different sanding authorizations, which means that "sanding authorization” (or “sanding release information”) means information as to whether there is authorization for sanding or not, or whether it is conditional. A number of different sections of the route have these sanding authorizations, i.e. whether sanding is prohibited, permitted or, if necessary, permitted with a condition. At least it must be clear whether sanding of a section of the route is permitted (e.g. the sanding authorization: “Sanding freely permitted”) or whether sanding is prohibited (e.g. the sanding authorization: “Sanding prohibited”).
- different route sections can be provided with different markings, e.g. B. a color marking or electronic identification.
- markings e.g. B. a color marking or electronic identification.
- a limit value should be linked to the relevant section of the route, in particular a limit value for a speed.
- This list includes at least information indicating permission and prohibition of sanding.
- it can also contain a conditional permission for sanding, for example from a certain speed, and the case should be clarified should happen if there is no information for a section of the route, e.g. B. whether sanding is then permitted or prohibited.
- Deployment can occur once, e.g. B. at the beginning of the journey or several times, with wireless data transmission being preferred.
- the provision can be made from a control center.
- Determining the position of a rail vehicle on the track while driving is known, e.g. B.
- Sensors e.g. balises
- the rail vehicle itself can determine this, e.g. B. by calculating a GPS position.
- Existing technology can be used, such as: B. is already used to release route sections or to receive signal information.
- the section of the route map on which the rail vehicle is located at a specific time can be determined. Since the route map contains spatially resolved sanding authorizations, it can be determined whether sanding authorization exists at the position of the rail vehicle or not. It should be noted that sanding permissions do not need to be assigned to the entire route. In addition to “permitted” and “forbidden”, the status "unknown” can also be present, whereby it can be defined in a default setting whether sanding is allowed to take place there or not.
- the sanding information can certainly correspond to the sanding authorization data (i.e e.g. B. "Sanding permitted", “sanding prohibited” or “sanding conditionally permitted” but also control commands for a sanding system (e.g. a control signal on a control line). It should be noted that the sanding authorizations are already in the form of Control commands may be present.
- the sanding system of the rail vehicle can then be controlled according to the generated sanding information. Since there should usually be a reason for sanding, in practice this control can be carried out in such a way that a manually or automatically generated sanding command is only executed if sanding is also permitted at the current position of the rail vehicle (based on the sanding information ), or if special circumstances exist (e.g. a manual override).
- the system according to the invention for controlling sanding of a sanding system of a rail vehicle while it is traveling on a route preferably by means of the method according to the invention, comprises the following components:
- a data interface designed to receive a route map of the route traveled with different sanding authorizations on different route sections, with at least one permission to sand the route section or a ban on sanding the route section being specified as the sanding authorization for a route section.
- a sanding determination unit designed to use the determined position to determine in which section of the route map the rail vehicle is located and which sanding authorization the person in question has route section is assigned, and to generate sanding information based on the specific sanding authorization
- the position unit can e.g. B. a radio position receiver, especially a GPS receiver, or a receiver for information from balises in the track. Basically, devices that are already known can be used for this purpose.
- the sanding determination unit is a unit which uses the data of the position unit and the received route map and determines from the determined position in which route section of the route map the rail vehicle is located and which sanding authorization is assigned to the relevant route section. It also serves to generate sanding information based on the previously determined sanding authorization.
- the sanding determination unit can be a single module but also a combination of two or more modules, e.g. B. It can include an individual module that generates the sanding information.
- the control unit can be a known control unit for sanding, which is modified according to the invention became . However, it can also be a control unit that is connected downstream of a sanding control and decides whether a sanding command reaches the sanding system ("sanding permitted") or not ("sanding prohibited").
- the rail vehicle according to the invention comprises a system according to the invention or a control unit designed for operation in a system according to the invention.
- the control unit must therefore allow control based on the sanding information.
- the method according to the invention for sanding control is used in a preferred rail vehicle.
- the electronic route map according to the invention includes different sanding authorizations on different sections of a route and is designed for use in a method according to the invention.
- the invention can be implemented in particular in the form of a computer unit, in particular in a control device, with suitable software.
- the computer unit can e.g. B.
- the computer unit can have one or more cooperating microprocessors or the like.
- it can be implemented in the form of suitable software program parts in the computer unit.
- a largely software-based implementation has the advantage that previously used computer units in multiple units or train sets or in their car in a simple way through a software or Firmware update can be retrofitted to work in the manner according to the invention.
- a corresponding computer program product with a computer program, which can be loaded directly into a storage device of a computer unit, with program sections in order to carry out all steps of the method according to the invention when the program is in the Computer unit is executed.
- a computer program product may optionally contain additional components such as. B. documentation and/or additional components, including hardware components such as: B. Hardware keys (dongles etc.) for using the software include.
- a computer-readable medium for example a memory stick, a hard drive or another transportable or permanently installed data carrier, can be used, on which the program sections of the computer program that can be read and executed by a computer unit are stored .
- the calculation program can also be transmitted via radio.
- the route map is stored in electronic form in a storage unit of the rail vehicle.
- it can be retrieved from a operations control center or another location via data transmission, in particular by radio. it is retrieved in this way as part of the procedure. It can be provided by a control center or by balises on the track and does not necessarily have to be complete.
- the position of the rail vehicle is determined using a radio positioning method, in particular GPS. Alternatively or additionally, it can be determined using balises on the route.
- the current position of the path traveled is calculated from the last balise passed over, particularly in the case of disturbed or non-existent radio reception (e.g. GPS reception).
- the position of the balises is particularly preferably stored in a route map in a storage unit of the rail vehicle, in particular the route map, which also contains the sanding authorization. A current sanding release or the sanding information is determined.
- the rail vehicle sends its current position to an operations control center.
- the operations center determines which section of the route map the rail vehicle is located in.
- Information about the route section or a related sanding authorization or sanding information generated from it can then be sent to the rail vehicle.
- the determination of which sanding authorization is assigned to the section of route in which the rail vehicle is located is carried out by an operations control center.
- the sanding information is generated by the operations control center.
- the Sanding information is then sent to the rail vehicle.
- the route map includes route sections whose sanding authorization allows sanding at a speed above a speed threshold (e.g. > 25 km/h) and prohibits sanding at a speed below the speed threshold. This is therefore a conditional right to sand.
- a speed threshold e.g. > 25 km/h
- the speed of the rail vehicle is preferably also measured. Sanding clearance is issued for the relevant route sections if such a route section is driven through at a speed greater than a speed threshold specified for this route section.
- the speed threshold is preferably freely definable for each route section.
- the sanding system of the rail vehicle is controlled in a special way: in the event that sanding is to take place, this is compared with the sanding information and sanding takes place when the sanding information indicates that sanding is permitted is . It will not occur if the sanding information indicates that sanding is prohibited. Alternatively or additionally, when manually activating a sanding, it is permitted if the sanding information indicates that sanding is permitted and not permitted if the sanding information indicates that sanding is prohibited.
- sanding is permitted by a predetermined control signal, even if the sanding information indicates that sanding is prohibited.
- a driver of the rail vehicle can initiate sanding with a control signal independently of the sanding information. It is preferred that before sanding, the rail vehicle sends a request for the release of the sanding to an operations control center and sanding can only take place if a release is transmitted to the rail vehicle by the operations control center. In practice, this case can e.g. B. occur on a steep climb in winter.
- a corresponding notification is always sent to an operations control center, stating the position of the sanding.
- the operations control center knows whether and where cleaning needs to be done or not.
- sanding authorizations for different route sections are assigned priorities. These priorities are specifically assigned to prohibitions on sanding, whereby the Sanding information particularly prefers the appropriate one
- Priority includes (this sanding information is used in addition to the options "sanding permitted” and “sanding prohibited”). In practice, this means that sanding may be prohibited, but there are different levels of prohibition and therefore may be necessary. different levels of bridging must be carried out. It is preferred that control commands for sanding are also assigned priorities which are comparable to the priorities of the sanding information. A sanding system is then controlled based on the component (which means the sanding information and/or the control command) with the higher priority. Here the control commands already include a certain "bridging function". A control command with a priority that reflects that sand must absolutely be used (e.g. because otherwise the rail vehicle cannot continue driving) can then override a ban that only one has a low priority (i.e. more like “normally not sent”). In this embodiment, a bridging is implemented.
- the route network is divided into areas (route sections) in which the respective type of sanding is defined (sanding release information or sanding authorization).
- sanding release information or sanding authorization can e.g. B. are: "Sanding freely permitted”, “Sanding prohibited”, “Sanding only permitted above a certain speed threshold”.
- a rail vehicle has stored a map of the route network in electronic form, which contains the information mentioned about the route sections.
- the system according to the invention calculates based on a Position, e.g. GPS position, which it receives from a corresponding receiver, which section of the route the rail vehicle is in and gives Based on the sanding authorization, sanding is permitted or prohibited in the respective section of the route using an appropriate calculation function. In the case of a speed-dependent release, the sanding is only released once this specified speed has been reached.
- a corresponding notification with location information is sent to the land-based IT infrastructure or is transmitted to the operations control center.
- this information can preferably also be stored on the land side in appropriate servers.
- the vehicle continuously transmits its own (GPS) position to the landside. This determines the current sanding information based on the corresponding route map and transmits this back to the rail vehicle, which uses this sanding information to calculate the sanding release.
- GPS global positioning system
- the advantage of the invention is that the sanding release is automatically calculated. This can be used without the involvement of a vehicle driver. Any information sent to the landside about unauthorized sanding also occurs automatically.
- the method is therefore suitable for reducing costs and improving operational quality and safety. It is particularly advantageous when using vehicles without a driver. even necessary.

- the central box which is intended to indicate a body of system 2 and receives data from a route map K that is available in system 2, e.g. B. in a storage unit (not shown here).
- the other is a radio receiver that can receive data from a route map K via radio (e.g. from a operations control center, not shown). It is an advantage if the system 2 receives the route map K via radio before the rail vehicle 1 travels, stores it in a storage unit and can therefore always access the route map K, even in radio dead spots.
- a position unit 5 designed to determine the position of the rail vehicle 1 on the route while driving.
- the position unit is 5 z.
- a sanding determination unit 6 designed to determine, by means of the determined position, in which route section X, Y, Z of the route map K the rail vehicle 1 is located and which sanding authorization is assigned to the relevant route section X, Y, Z, and to generate sanding information S based on the specific sanding authorization.
- the can Sanding determination unit 6 also receives speed data G of the rail vehicle 1 if there is a conditional ban on sanding, which is linked to a minimum speed.
- the sanding information S is sent to a control unit 7, which is designed to control the sanding system 3 of the rail vehicle 1 with this sanding information S.
- This can be the normal control unit 7 of the sanding system 3, which has been modified according to the invention, or an additional control unit 7 which acts on the sanding system 3.
- Figure 3 shows a block diagram of a preferred process sequence for a method according to the invention for controlling sanding of a sanding system 3 of a rail vehicle 1 while it is traveling on a route T such as. B. shown in Figure 1.

- This route map K includes several different route sections X, Y, Z with different sanding authorizations, with at least one permission to sand the route section .
- the route map K can also include route sections 1 is measured and a sand release for a relevant section of route X, Y, Z exists when this route section X, Y, Z is traveled through at a speed greater than a speed threshold specified for this route section X, Y, Z.
- the route map K should be available before the journey, but can also be provided later.
- the provision can e.g. B. take place as shown in Figure 2.
- step II the position of the rail vehicle 1 on the route is determined during the journey. This can be done via GPS as indicated in Figure 1 or using balises on the route.
- step I I I the determined position is used to determine in which route section X, Y, Z of the route map K the rail vehicle 1 is located and which sanding authorization is assigned to the relevant route section X, Y, Z.
- an “x” is intended to indicate that sanding is prohibited in the current section Y, to which the arrow in step II points.
- step I I I sanding information S is also generated based on the specific sanding authorization (here also an “x” for a sanding ban).
- step IV the sanding system 3 of the rail vehicle 1 is controlled according to this sanding information S.
- the method can be carried out in the rail vehicle 1, in an operations control center or in both.
- sanding can take place despite the ban.
- sanding can be permitted by a predetermined control signal, even if the sanding information S indicates that sanding is prohibited.
- a driver F of the rail vehicle 1 can z. B. initiate sanding with a special control signal independently of the sanding information S, e.g. B. if rail vehicle 1 can no longer move without sand.
- sanding authorizations can be assigned different priorities for different route sections X, Y, Z, at least in the case of sanding bans.
- Control commands for sanding can also have such priorities and in the case where a control command has a higher priority than the ban, sanding can occur despite the ban.
