Definitions
- the invention relates to a system for determining Meßgössen on a rotating component, such as a shaft or a rotating body comprising at least a passive RFID sensor unit with a sensor, a Energyversor- supply unit, a transmitting unit and an antenna and an RFID reader with an antenna wherein the RFID reader is arranged on a base and the RFID sensor unit on the component.
- condition monitoring US 2010 0 315 204 A1 discloses a system based on RFID technology in which a sensor is mounted on the surface of a shaft and the measured data is then applied via a RFID transponder transmitted to an RFID reader.
- the proposed systems have the disadvantage that the measurement data or the energy can only be transmitted if the field profiles of the antennas of transmitter and receiver are aligned.
- the sensor unit In the arrangement of the sensor unit on the planet carrier so once per revolution.
- the well-known RFID technology works in general in the 125 kHz technology which is best suited for the reading out of fixed data (IDs).
- IDs fixed data
- The- The RFID chips carrying the data enter the field of the antenna, are activated and interrogated, and then leave the field of the antenna again. Only very slow relative speeds are provided (up to 10 m / s) and large antenna areas and antenna areas (a few m 2 ).
- rotary bodies such as turbo couplings, in which it is particularly interesting to know the temperature of the working fluid during operation, there are currently only unsatisfactory solutions such as fuse screws over which the working fluid in overheating in the environment will drain (harm to the environment ).
- a switch can be placed in the rotating system when a temperature has been exceeded. Both methods are irreversible and only work when the coupling is rotating. At standstill, both systems have no effect.
- An object of the invention is therefore to propose a system by means of the Meßgössen to a rotating component, such as a shaft or a rotating body, can be detected continuously and safely.
- a system for determining measurement casings on a rotating component, such as a shaft or a rotating body, comprising at least one passive RFID sensor unit with a sensor, a power supply unit, a transmission unit and an antenna and an RFID reader with an antenna, wherein the RFID reader is arranged on a base and the RFID sensor unit is arranged on the component.
- the system is characterized in that the antenna of the RFID reader and the antenna of the RFID sensor unit are arranged in such a way that the antenna of the RFID sensor unit moves during the movement essentially in the antenna field region of the antenna of the RFID reader, so a substantially uninterrupted transmission of energy and / or data is ensured.
- a passive RFID sensor unit also referred to as RFID transponder or TAG, means a unit without its own energy unit, such as a battery. The required energy is induced via the antenna. - -
- the RFID sensor unit or TAG can be arranged on or in a component or a shaft or a rotating body.
- the rotary body may also be a fluid-filled hollow body, such as a turbo coupling, which consists of two independently rotatably mounted paddle wheels.
- the base on which the RFID reader is arranged is a holding device by means of which the reader or in particular its antenna is held in position relative to the component.
- the base comprises an annular antenna carrier for the reader antenna, which is arranged centrally with respect to the axis of rotation of the component.
- the RFID reader can be connected to an evaluation unit, such as a computer, which in turn is connected to the control of the transmission.
- the energy required to measure operating parameters is transmitted from the RFID reader to the TAG, wherein an energy storage unit can alternatively be arranged on the TAG for temporary storage of energy.
- the RFID sensor unit or TAG is connected to at least one sensor.
- the sensor can be arranged on the TAG or electrically connected thereto.
- the antenna can be designed as a double-flow antenna.
- Two-flow antennas are antennas which are loop-shaped or whose antenna wire is guided in a loop.
- the reader antenna can be embodied such that it forms a rotationally symmetrical or annular antenna field on the movement radius of the rotating TAG antenna.
- the reader antenna may comprise a plurality of parallel windings, which are arranged offset to one another.
- a multi-core reader antenna cable can be used, which is positioned in a tube loop which is bent in an annular manner or in a plastic carrier. This ensures that it is in the antenna overlap - - Field to a smaller field fluctuation comes, so that even at high speeds a virtually uninterrupted antenna function is guaranteed.
- the reader antenna and the TAG antenna can be arranged in two essential orientations to each other, in the axial or radial direction.
- temperature sensors and sensors can be used by means of which one of the following operating parameters pressure, humidity, torques and / or vibrations can be detected.
- the senor can be arranged on or within the component and detect operating parameters there.
- the sensor is arranged such that the temperature of the fluid can be measured at least in a standstill position and during operation
- the several RFID tags are provided, all of which communicate by means of an RFID reader 's and are powered by them with energy. Wherein coded data can be transmitted to divide the measuring points.
- Figure 1 a schematically known from the prior art functional principle of an RFID system is shown.
- the illustrated system allows - - a contactless signal and energy transfer.
- the system consists of a sensor 6 which is connected to an RFID sensor unit 2 and an RFID reader 1 which is connected to an apparatus unit 25.
- the antenna fields of the antennas 3a and 3b of Reader 1 and TAG 2 interlock.
- Figure 1 b shows the more detailed structure of the RFID system. In this illustration, all components that can be arranged on a reader 1 and a TAG 2 are shown.
- RFI D-TAG 2 and RFID reader 1 must be positioned in the radio range to each other or the antennas are positioned to each other such that the field characteristics of Mesh antennas.
- the RFID tag 2 in addition to the circuit for transmitting and receiving signals and energy having a power supply unit, which provides for the power supply of the circuits. For storing the energy, an energy storage unit may be provided.
- a passive RFID tag is therefore generally referred to as a smart sensor.
- FIGS. 2a to 2e show a turbo coupling in different views or sections.
- Figure 2a shows a turbo coupling 7 at a standstill.
- the turbo coupling is arranged between a drive and a transmission.
- the torque transmission takes place by means of the hydrodynamic principle.
- in the working space of the turbo coupling formed by the first and second impeller, so long forms a circulation flow until in nominal operation there is almost a speed equality.
- As long as no speed equality forms a circulation flow.
- the higher the Diffenenzcard between the first and second paddle wheel the greater the power loss through which the working fluid is heated. In the event of a malfunction, overheating of the working medium can occur very quickly, which requires a shutdown of the drive.
- Figure 2b is the view of the first paddle wheel 8, the drive side, shown with the RFI D measuring system.
- the RFID tag 2 is fastened or screwed on the paddle wheel 8 such that the sensor extends into the working space 10.
- the positioning of the TAG ' s 2 and the sensor 6 is so - - chosen that the measurement takes place at the outer radius of the working space 1 1, since the highest temperatures can prevail here.
- the RFID reader unit consisting of the reader 1 and the antenna 3a.
- the antenna 3a is positioned on an antenna carrier 21, which is arranged as a ring around the shaft region 15.
- the antenna 3a is designed as a loop, so that a double-flow antenna is formed, which is connected to the antenna board 19 such that the antenna overlap region 17 causes as possible no field weakening.
- the one or multi-wire antenna wire can be cast in the grooves 14.
- the reader 1 is connected to the antenna via an antenna feed line 20.
- FIG. 3 shows embodiments of the RFID reader antenna 3a.
- the antenna 3a In order to be able to construct an antenna field region by means of the antenna 3a, which ensures a substantially uninterrupted transmission of energy and / or data, the antenna 3a must be designed in such a way that a double-flow antenna is produced. This is achieved by the antenna wire as shown in FIG. - - As a loop is formed into an annular structure. Between the feed and return wire an antenna field is created whose field strength is amplified perpendicular to the ring surface.
- Such a designed antenna generates a directional antenna field perpendicular to the ring surface, concentrating the field area in front of the antenna and less affecting the environment, thereby improving the EMC characteristics.
- the field increase or weaken the field but only affects a small section area of the antenna ring surface, so that an essentially uninterrupted transmission can take place.
- the antenna wire can be mounted on an antenna support or alternatively guided in a metal tube 23, the tube then being deformed to form an annular structure in which the tube forms two concentric circles enclosing an annular surface.
- a single or multi-core antenna wire can be used or the tube 23 itself serve as an antenna wire.
- the circular ring diameter or the distance of the loop ie the distance between the external antenna and internal antenna is dependent on the movement of the RFID tag 's or the antenna 3b. That is, the antenna ring 3a must be designed so that the antenna 3b of the RFID-TAG ' s always remains in the region of the annular surface during the rotation.
- the antenna overlap region 17, the antenna 3a, as shown in FIG. 3c, can be made multi-core.
- Each core forms its own ring surface, that is, the individual wires are connected in parallel. Due to the spatial displacement of the individual turns to each other a field fluctuation can be well balanced.
- the individual windings are connected accordingly on the antenna board.
- 4 shows an embodiment of a tag 's 2 is exemplified. Especially at high temperatures, it is necessary that the tag board is too large. - - ze is protected.
- the illustrated housing 26 of the TAG ' s 2 is designed as a Einschraubgepatuse, the sensor 6 is positioned at the top and can be brought so close to a temperature range.
- the TAG board 2 on the other hand, is well shielded from heat. For further isolation from the heat and for attachment, the TAG is fixed in the housing 26 by means of an insulating material 24.
