Definitions

  • the invention relates to a rail system with a rail and mobile parts that can be moved along the rail.
  • a rail system is designed with a rail and mobile parts that can be moved along the rail.
  • the closest state of the art is a device for ensuring the distance between track-bound vehicles.
  • a conductor rail system is known from DE 20 2016 104 836 U1.
  • a communication system is known from the "smg slotted microwave guide" from Vahle Communication Systems.
  • a transport system is known from DE 10 2012 006 412 A1.
  • the invention is therefore based on the object of developing a rail system in which data transmission is to be carried out more simply and cost-effectively.
  • the object is achieved in the rail system according to the features specified in claim 1.
  • the advantage here is that data can be transmitted between movable handsets by sending and receiving modulated light. Furthermore, the data can also be transmitted between the movable handset and stationary transmitters and receivers.
  • the use of a profile part which has an opening slot extending in the direction of the rail enables interference-free or at least low-interference data transmission. This is because light coming from the environment can be almost completely shielded.
  • the range of the data transmission is increased because the light intensity decreases more slowly with increasing distance in the cavity than in free space. The narrower the slot, the lower the losses and thus the greater the range.
  • the handset has leg areas that protrude into the cavity, which hold a transmitter and receiver into the cavity.
  • an absorber is arranged in the rail direction between the areas of the mobile part,
  • the absorber is made of a brush, fleece, or plastic.
  • the absorber touches the profile part in a circumferential angular range of more than 180° relative to the rail direction, or is at least closer to the profile part than the areas of the mobile part or than the mobile part itself. It is advantageous that the absorber can be provided almost touching the profile part or even rubbing against the profile part.
  • the transmitter and receiver arranged in a respective area, in particular the leg area, of the mobile part are each arranged on the side of the area facing away from the absorber.
  • a first spatial area for data transmission arranged at the front in the rail direction, is separated by the absorber from a second spatial area for data transmission, arranged at the rear in the rail direction.
  • the data transmission channel located in the cavity in front of the respective absorber in the direction of the rail is separated from the data transmission channel located in the cavity in the direction of the rail behind the absorber. This is advantageous in that low-interference data transmission is enabled.
  • the advantage here is that data can be transmitted not only via the slotted waveguide, but also via light within the same spatial area. This allows for either a higher data transmission rate or greater security, since the data can be transmitted using two different physical principles.
  • the mobile unit is movable and guided along the rail by means of wheels and/or rollers. It is advantageous that the mobile unit is designed as a rail vehicle.
  • an LED or a laser diode for visible or infrared light is used as the transmitter and/or A photodiode or phototransistor is used as a receiver to detect visible or infrared light.
  • a photodiode or phototransistor is used as a receiver to detect visible or infrared light.
  • the advantage here is that light can be used.
  • a transmitter and a receiver are accommodated in a recess of the profile part,
  • the recess is a round hole or a bore whose round hole symmetry axis or bore axis forms an angle of between 10° and 60° to the rail direction, and/or the recess extends continuously through the profile part and/or through the wall of the profile part.
  • the profile part is in one piece with the rail, In particular, it is designed as a single piece.
  • the advantage here is that the profile part is integrated with the rail, eliminating the need for precise relative alignment prior to joining, since the production as a continuous casting already results in the integrated rail part.
  • the profile part has two cavities extending parallel to one another, in particular spaced apart from one another. This advantageously allows for the use of not only a monochrome half-duplex method, but also a monochrome full-duplex method for data transmission.
  • the profile part has only a single, elongated cavity.
  • the advantage here is that a full-duplex process can be implemented by using two different colors, even if only a single, non-separated communication medium is available.
  • the cross-section of the respective cavity is invariant, in particular unchangeable, along the rail direction.
  • the profile part can be manufactured as a drawn part or as a continuous cast part.
  • the cross-section in the initially formed profile part is constant. Round holes or bores can then be drilled into the profile part as post-processing to accommodate the stationary transmitter and receiver. If the profile part is made of plastic, a coating can also be applied.
  • the opening of the respective cavity or cavities is designed as a slot extending in the direction of the rail. This is advantageous in that the mobile part, during its movement, can protrude into the cavity through the slot by means of the regions, in particular the leg regions, and can be moved parallel to the slot. Therefore, it is important that the slot direction is aligned parallel to the rail direction.
  • the profile part is made of plastic, in particular as a drawn part, or that the profile part is made of metal, in particular as an extruded aluminium part.
  • the advantage here is that simple, cost-effective production is possible and the profile part has the same translational symmetry as the rail, in particular which itself is manufactured as a continuous casting or drawn part.
  • the profile part 5 has a cavity which is open towards a first side.
  • the profile part 5 is arranged parallel to a rail of a system designed as a rail system.
  • the rail is preferably made as a metal profile part.
  • the profile part 5 is preferably made of plastic, with the cavity of the profile part 5 having mirrored side surfaces.
  • the mirroring is preferably produced by vapor deposition with the metal, in particular chromium or a chromium-containing alloy.
  • each mobile unit 6 extends at least partially into the cavity of the profile part 5, so that each mobile unit 6 has a transmitter 4 and a receiver 3 on the front side in the direction of the rail. Likewise, each mobile unit 6 also has a transmitter 4 and a receiver 3 on its rear side.
  • the mobile unit 6 In the rail direction, between the transmitter 4 and receiver 3 on the front and rear sides, the mobile unit 6 has an absorber that absorbs the radiation emitted by the transmitters 4, in particular light radiation. In this way, the cavity in front of the absorber 7 in the rail direction and the cavity behind the absorber 7 in the opposite direction to the rail direction are separated from the radiation, thus forming two separate data communication areas.
  • the handset 6 is able to exchange data with another handset 6 spaced apart in the direction of the rail and also with a third handset 6 spaced apart opposite to the direction of the rail.
  • the handsets 6 are constructed identically to one another.
  • At least one transmitter 2 and one receiver 1 are stationary on the profile part 5.
  • data can also be transmitted between a mobile unit 6 and the stationary transmitter 2 and receiver 1.
  • the cavity formed in profile part 5 has a cross-sectional profile that remains constant in the rail direction. This is because profile part 5 can be manufactured as a continuous casting.
  • the cavity is open to the environment, the clear width of the cavity narrows increasingly with decreasing distance from the cavity's opening to the environment.
  • the cavity has a slit as its opening and/or mouth.
  • An LED for the visible or infrared light range can preferably be used as the transmitter (2, 4) and a correspondingly light-sensitive component, such as a phototransistor or photodiode, can be used as the receiver (1, 3).
  • a correspondingly light-sensitive component such as a phototransistor or photodiode
  • the respective absorber 7 is arranged on the respective mobile part 6 in such a way that the distance to the profile part 5 is as small as possible, in particular disappears.
  • the area of the mobile part 6 which projects into the cavity is designed with two leg areas spaced apart from one another in the direction of the rail, in particular in a U-shape.
  • a transmitter 4 and a receiver 3 are arranged on each of the two legs.
  • Absorber 7 is arranged on the mobile unit between the two legs, facing the rail. Absorber 7 preferably extends beyond the legs in all transverse directions relative to the rail.
  • transmitters 2 and 4 are all operated with the same frequency, i.e. color, only a half-duplex method can be used for data transmission.
  • the profile part there is designed with two parallel cavities. Each of these cavities is similar to the cavity in the embodiment according to Figures 1 to 3 .
  • the mobile part 40 now extends into both cavities.
  • the mobile part 40 preferably has two leg regions for each cavity, so that a transmitter 4 and a receiver 3 are arranged in each cavity at a respective leg region in the rail direction, and a transmitter 4 and a receiver 3 are arranged at a respective leg region opposite to the rail direction.
  • an absorber 7 is arranged in the rail direction between the two respective leg areas, in particular according to the design according to Figures 1 to 3
  • the cavity is thus separated by the absorber 7, particularly for light.
  • the absorber 7 particularly for light.
  • In the direction of the rail in front of the mobile part spreading light is separated from the area of the room arranged behind the handset in the direction of the rail.
  • the respective profile part (5, 41) is made of a metal, such as aluminum.
  • the surface of the material bordering the respective cavity reflects radiation, in particular visible or infrared light.
  • the respective profile part (5, 41) can be manufactured from plastic, in particular as a plastic profile part.
  • the surface of the material bordering the respective cavity is coated with a radiation-reflecting layer, in particular with a chromium layer or chromium-containing layer.
  • the rail and the profile part (5, 41) are made of the same material and are therefore integral, i.e., one-piece.
  • the cavity or cavities are integrally formed on the rail. Therefore, only the rail needs to be installed when manufacturing the rail system.
  • the mobile parts (6, 40) are then placed on the rail, and their leg portions extend into the cavities, so that transmitters 4 and receivers 3 arranged on the leg portions radiate radiation into the cavities.
