Technical Field
[0001] The utility model relates to a transportation system, and the transportation system has a moving device that can move along a driving section, in particular along a track. Background Art
[0002] As is well known, in a track-guided transportation system, there is a moving device that can move along a driving section, in particular along a track. Summary of the Utility Model
[0003] Therefore, the object of the utility model is to improve a transportation system, wherein the data exchange link with the moving device should be improved with a relatively high operating distance.
[0004] In terms of the transportation system, an important feature of the utility model is that the transportation system is designed to have a moving device that can move along a driving section, in particular along a track.
[0005] Wherein, the slotted waveguide of the transportation system is arranged in parallel with the driving section, the slotted waveguide surrounds a cavity, and the cavity communicates with the environment through slots / slits that penetrate the slotted waveguide along the driving section direction, in particular along the track direction.
[0006] Wherein, the moving device has an antenna, and the antenna extends through the slot of the slotted waveguide into the cavity of the slotted waveguide, in particular for inputting or outputting electromagnetic waves.
[0007] Wherein, the slotted waveguide is made of a steel plate into a bent part.
[0008] The advantage here is that, by moving the moving device in parallel with the extending direction of the slot of the slotted waveguide, and during this movement, inputting electromagnetic waves into the cavity of the slotted waveguide by means of the antenna, data can be transmitted contactlessly by the moving device. The electromagnetic waves propagate in the cavity as a cavity radiation mode and can be received by another antenna that also extends into the cavity. Therefore, a high data stream can be transmitted. The operating distance of data transmission through the cavity of the slotted waveguide is at least also associated with the loss power of the transmission of electromagnetic radiation in the slotted waveguide. For this purpose, a steel plate is used as the slotted waveguide. In this way, a small loss power can be achieved and thus a high operating distance can be achieved. In addition, mechanical and chemical properties suitable for use as a slotted waveguide can be achieved. That is, the plate is bent during manufacturing, and during this processing, material failure can be avoided and corrosion can also be prevented.
[0009] In an advantageous design, the plate has less than 0.07% carbon, in particular having carbon between 0.04% and 0.06%. The advantage here is that a 90° bend can be made during manufacturing without the plate failing. In addition, corrosion can also be prevented.
[0010] In an advantageous design, the plate has less than 1% silicon, in particular between 0.5% and 0.6% silicon. The advantage here is that the plate has a sufficiently high mechanical stability. In addition, corrosion can be prevented.
[0011] In an advantageous design, the plate has less than 2% manganese, in particular between 1.1% and 1.2% manganese. The advantage here is that corrosion can be prevented and the mechanical stability of the slotted waveguide is sufficiently high.
[0012] In an advantageous design, the plate has less than 0.045% phosphorus, in particular between 0.02% and 0.04% phosphorus. The advantage here is that corrosion can be prevented and the mechanical stability of the slotted waveguide is sufficiently high.
[0013] In an advantageous design, the plate has less than 0.03% sulfur, in particular between 0.002% and 0.004% sulfur. The advantage here is that corrosion can be prevented and the mechanical stability of the slotted waveguide is sufficiently high.
[0014] In an advantageous design, the plate has between 17.5% and 19.5% chromium, in particular between 18.3% and 18.4% chromium. The advantage here is that corrosion can be prevented and the mechanical stability of the slotted waveguide is sufficiently high.
[0015] In an advantageous design, the plate has between 8.0% and 10.5% nickel, in particular between 8.0% and 8.1% nickel. The advantage here is that corrosion can be prevented and the mechanical stability of the slotted waveguide is sufficiently high.
[0016] In an advantageous design, the plate has less than 0.1% nitrogen, in particular between 0.050% and 0.053% nitrogen. The advantage here is that corrosion can be prevented and the mechanical stability of the slotted waveguide is sufficiently high.
[0017] In an advantageous design, the plate is a stainless steel plate. The advantage here is that the mechanical properties can be optimized, where corrosion can be prevented and the mechanical stability of the slotted waveguide is sufficiently high.
[0018] In an advantageous design, the plate is an austenitic stainless steel plate. The advantage here is that the mechanical properties allow the slotted waveguide to be arranged unsupported / floating in the transport system.
[0019] In an advantageous design, the slotted waveguide has six curved sides, all of which are designed to be parallel to each other. The advantage here is that the slotted waveguide has only a small number of curved sides, and the bending angle does not exceed 90° here.
[0020] In an advantageous design, the slotted waveguide is fixed to the continuous casting profile part acting as a track by a holding mechanism.
[0021] The moving device has a plurality of wheels rotatably supported, and these wheels roll on the continuous casting profile part. The advantage here is that during the movement of the moving device, data can be exchanged contactlessly through the slots of the slotted waveguide by the antenna of the moving device.
[0022] In an advantageous design, a primary conductor designed as a linear conductor is arranged on the continuous casting profile part, and an intermediate frequency alternating current is applied to the primary conductor.
[0023] The moving device has a secondary winding, and the secondary winding is inductively coupled to the primary conductor.
[0024] The secondary winding is connected in series or in parallel with such a capacitor that the resonance frequency of the oscillating circuit formed by the capacitor and the secondary winding is equal to the frequency of the alternating current.
[0025] The secondary winding feeds a rectifier, and the electrical load of the moving device, in particular a power unit designed as an electric motor, is supplied with power from the connection on the DC voltage side of the rectifier. The advantage here is that contactless power supply can be achieved with high efficiency even in the case of only weak and / or fluctuating inductive coupling.
[0026] In an advantageous design, a higher frequency current component is modulated into an alternating current.
[0027] The higher frequency voltage component induced by the higher frequency current component of the primary conductor in the secondary winding can be output capacitively, in particular through a capacitor, and can be fed to the control electronics of the moving device.
[0028] The advantage here is that data can be transmitted contactlessly and redundantly in a completely different physical manner, namely in particular as cavity radiation or as inductive transmission.
[0029] In particular, the higher frequency current component is modulated into an alternating current so that data can be transmitted through the inductive coupling between the primary conductor and the secondary winding.
[0030] The higher frequency voltage component induced by the higher frequency current component of the primary conductor in the secondary winding can be output capacitively, in particular through a capacitor, and can be fed to the control electronics of the moving device.
[0031] In particular, the transport system is arranged such that the data transmitted through the slotted waveguide can also be transmitted and / or can be transmitted, in particular redundantly and contactlessly, through the inductive coupling between the primary conductor and the secondary winding.

Description of the Drawings
[0033] The present utility model will now be described in detail with reference to the schematic drawings:
[0034] Figure 1 Shows an oblique view of a slotted waveguide of a transport system according to the present utility model.
[0035] List of Reference Numerals:
[0036] 1 Slotted waveguide
[0037] 2 Flange region
[0038] 3 Connection region
[0039] 4 Wall region
[0040] 5 Cover region Detailed Description of the Preferred Embodiments
[0041] As shown in the drawings, the transport system includes a slotted waveguide 1 through which a mobile device can transmit data, and the mobile device moves along the slotted waveguide.
[0042] For this purpose, the mobile device is preferably guided by a guide rail and can thus move parallel to the extension direction of the slotted waveguide.
[0043] The mobile device has an antenna that passes through the slot of the slotted waveguide, and electromagnetic radiation can be input into the cavity of the slotted waveguide by means of this antenna. The radiation propagates in the cavity along the extension direction of the slotted waveguide and can be output through another antenna that extends into the cavity and is either fixedly arranged so as to enable data exchange with the central control device of the transport system, or alternatively fixed to another mobile device that can exchange data with the first mobile device 1.
[0044] The slot of the slotted waveguide preferably points downwards, or at least so that the liquid automatically flows out of the internal space.
[0045] The slot is defined by two flange regions 2 that are preferably parallel to each other, and these two flange regions are connected to the housing region of the slotted waveguide 1 through their respective connection regions 3. Here, the housing region includes a bottom region 5 that is connected to the flange region 2 through a wall region 4.
[0046] Preferably, these wall regions are parallel to each other and the normal direction of the flat bottom region 5 has an angle of 90° with the normal direction of the flat wall region 4. The normal direction of the wall region 4 has an angle of less than 90° with the normal direction of the corresponding adjacent connecting region 3.
[0047] These flat flange regions 2 are parallel to the wall region 4.
[0048] The width of the slotted waveguide in a direction transverse to the extension direction of the slotted waveguide, i.e., in particular in the normal direction of the wall region 4, is initially constant as the distance from the bottom region 5 increases. In particular, the width is equal to the distance between the wall regions, and then the width decreases proportionally with respect to the distance from the bottom region 5 until the width is equal to the distance between the flange regions 2.
[0049] Preferably, the slotted waveguide 1 is designed as a bent sheet metal part.
[0050] As the sheet metal part for manufacturing the slotted waveguide 1, in particular an austenitic stainless steel sheet is used, which has less than 0.07% carbon. Preferably, carbon between 0.04% and 0.06% is used.
[0051] The sheet has less than 1% silicon. Preferably, silicon between 0.5% and 0.6% is used.
[0052] The sheet has less than 2% manganese. Preferably, manganese between 1.1% and 1.2% is used.
[0053] The sheet has less than 0.045% phosphorus. Preferably, phosphorus between 0.02% and 0.04% is used.
[0054] The sheet has less than 0.03% sulfur. Preferably, sulfur between 0.002% and 0.004% is used.
[0055] The sheet has chromium between 17.5% and 19.5%. Particularly preferably, chromium between 18.3% and 18.4% is used.
[0056] The sheet has nickel between 8.0% and 10.5%. Particularly preferably, nickel between 8.0% and 8.1% is used.
[0057] The sheet has less than 0.1% nitrogen. Preferably, nitrogen between 0.050% and 0.053% is used.
[0058] Preferably, the above percentage data are mass percentages.
[0059] Due to the above chemical composition of the stainless steel sheet, the slotted waveguide has high magnetic permeability, low hysteresis loss, good magnetic saturation during inductive transmission, and is particularly suitable for high-frequency electromagnetic radiation, in particular cavity waves.
[0060] Moreover, the stainless steel plate is corrosion-resistant and has good mechanical properties.
[0061] For manufacturing, a laser cutting tool is used for cutting, and the plate is bent along the bending edge.
[0062] In this way, high-precision manufacturing of the slotted waveguide can be achieved.
[0063] In other embodiments according to the present utility model, a plurality of slotted waveguides with the same design are arranged successively in the traveling direction, so that no gap is formed between the adjacent slotted waveguides. Therefore, a very long slotted waveguide can be generally constructed, and thus information transmission can be provided along the entire traveling section. With the above material composition, a large range of action for information transmission can be achieved because the loss is extremely small.
