Definitions
- Rail system with rail, coding system and mobile part that can be moved along the rail and method for operating a rail system
- the invention relates to a rail system with a rail, a coding system and a mobile part that can be moved along the rail, and to a method for operating a rail system.
- a mobile part can be implemented as a rail vehicle and can reach various rail positions in a rail system. It is also known that rails are profile parts, that is, have a constant cross section that cannot be changed in the direction of the rails.
- a system with a moving body is known from DE 60 2005 002 386 T2.
- the invention is therefore based on the object of simply and reliably determining a rail position.
- the object is achieved in the rail system according to the features specified in claim 1 and in the method in the features specified in claim 13.
- the coding system has segments arranged one behind the other in the direction of the rail, which are fastened to the rail, in particular screwed, wherein the mobile part has a sensor for determining the distance between the sensor and the segment of the coding system that is closest to the sensor, each segment having a coding area and a detection area.
- the rail can be produced as a profile part, that is to say with a constant invariable cross section in the rail direction, and the rail position can nevertheless be determined by a distance measurement in the direction of the rail because the segments in
- Rail direction have a variable height and / or wall thickness.
- the segments on the rails are in an area outside the running surface of the wheels of the
- Detection area of the segment a position on the segment can be uniquely assigned to each measured distance.
- the coding area by determining the changes in distance when the sensor traverses the coding area, the coding and thus identification information that is uniquely assigned to the segment can be determined.
- a rail position is stored for each piece of identification information in a list in the memory of an evaluation unit.
- an absolute rail position of the mobile part can be determined.
- the rail has a running surface on which a wheel of the mobile part can be rolled, the segment being spaced from the running surface.
- the surface of the detection area of the respective segment is on a straight line that is aligned parallel to the rail direction and intersects the sensor, has a particularly shortest distance that decreases monotonically in the rail direction, in particular proportional to the rail length and / or to the coding area of the Segment-related distance decreases.
- a rail position can be uniquely assigned to the distance in the detection area.
- the rail is a profile part, in particular
- the distance from the sensor is determined recurring over time and the sensor is connected to an evaluation unit via a data transmission channel to forward the values of the distance recorded by the sensor, the evaluation unit being used as a means for determining the rail position of the sensor and / or the mobile part acts.
- the evaluation unit can be arranged on the mobile part or stationary. In the latter case, however, a
- each segment is assigned a coding area, in particular for the individual identification of the segment in the rail system.
- identification information can be assigned to each segment.
- the coding region has a height profile which has regions in succession in the rail direction, in particular adjacent regions, the smallest distance of which from the straight line in the rail direction has successively different discrete values.
- Identification information can be coded by means of the height profile of the segment.
- the areas in the rail direction are preferably of the same length, so in particular each area has the length A / N, where A is the length of the coding area in the rail direction, where N is the number of areas of the coding area.
- the magnitude of the difference between the shortest distances measured in relation to the straight line between two areas that are closest to each other is less than m * A / N, where A is the length of the coding area in the direction of the rail,
- N is the number of areas of the coding area
- m is the gradient of the segment in the detection area, i.e. the amount of the quotient from the change in distance in relation to the straight line and the length of the detection area measured in the direction of the rail.
- the senor detects the distance recurring in time with such a repetition rate and the speed of the mobile part is limited in such a way that the amount of change in distance related to the straight line within the coding area is much greater than in the remaining detection area of the segment.
- the generated by the sensor is evaluated
- Sensor signal that is, the distance values detected by the sensor, determines the change in the distance values, in particular where the sensor is the distance to the closest to the sensor
- the segment is determined in a periodically recurring manner, in particular, and the associated change amount is determined when the detected distance value changes.
- Coding area is distinguishable.
- an odometric system for detecting the rail position of the mobile part is also provided, in particular with a running wheel rolling on the or another running surface.
- the advantage here is that the reliability of the determination of the rail position can be increased.
- Important features of the method for operating a rail system are that when the mobile part is moved, in a first method step the segment is identified from the distance values determined in the coding area, in particular from the changes in the distance values determined in the coding area, and an associated segment is identified from a memory
- the distance to the coding area of the segment is determined from the distance determined by the sensor in the detection area and from the distance and the rail position assigned to the segment
- the advantage here is that a simple and reliable determination of the rail position can be carried out. Because the segment is mechanically robust and therefore stable against environmental influences.
- the rail position assigned to the segment can be determined in the coding area and the position of the mobile part relative to a point on the segment can be determined in the detection area.
- the rail position of the mobile part is also determined odometrically.
- the advantage here is that the security of the position determination can be improved. Further advantages result from the subclaims.
- the invention is not restricted to the combination of features of the claims. For the person skilled in the art, there are further sensible possible combinations of claims and / or individual claims
- the rail system has a rail and a mobile part designed as a rail vehicle and movable along the rail.
- the mobile part has wheels that roll on a running surface of the rail.
- the rail is made as a profile part, in particular an extruded profile part.
- the rail thus has a cross section that is independent of the rail position, in particular that is always the same in the rail direction.
- a sensor 1 is attached to the mobile part and functions as a distance measuring device in that it determines the distance between sensor 1 and a coding system attached to the rail.
- the coding system is attached to the rail outside the running surface, in particular screwed on by means of screws.
- the coding system consists of preferably metallic segments, which in
- Rail direction are arranged one behind the other, in particular each touching one another or regularly spaced from one another.
- Each segment has the length X and has a coding area, in particular the coding area having the length A, where A is smaller than X.
- a detection area 3 in which the wall thickness of the segment in the rail direction increases proportionally to the rail length, in particular the distance to the coding area 2 of the respective segment. This increase, which is proportional to the length of the rail, i.e. the decrease in the distance to a through the sensor 1
- the wall thickness is the thickness of the segment, which is measured perpendicular to the rail direction, in particular in the direction of the sensor 1, in particular in the direction of that straight line which runs through the sensor 1 perpendicular to the rail direction.
- the coding area 2 has a height profile, that is to say a profile of the wall thickness seen in the rail direction, which has different discrete values one after the other in the rail direction.
- the coding area 2 has the length A in the direction of the rail and contains N plateaus, that is to say codes N discrete distance values.
- the plateaus are preferably of the same length in the direction of the rails, so in particular each of the plateaus has the length A / N.
- the coding is preferably carried out in such a way that the difference between two next adjacent plateaus is smaller than m * A / N.
- the coding area 2 is clearly recognizable together with the sensor 1. This is because the change per rail length is much greater within the coding area 2 than in the rest of the detection area 3 of the segment.
- the evaluation of the sensor signal generated by the sensor takes place by determining the change in the distance values.
- the sensor 1 detects the distance to the segment closest to the sensor 1 in a regularly recurring manner. If the detected distance value changes in the process, the associated change amount is determined.
- the amount of change can be used to determine whether the
- Coding area 12 or the detection area 3 is detected by the sensor 1.
- a coding area 2 is assigned to each segment.
- the coding area 2 is first passed over for each segment and the segment can thus be individually identified. Then the distance between sensor 1 and the segment is determined in the detection area and the distance value determined in this way
- an odometric sensor is additionally provided on the mobile part, which preferably has a running wheel rolling on the rail, the angular position of which can be used as an odometrically determined rail position.
