  • the conductor loop is inversely used for power supply of the transponder chip. If the conductor loop is destroyed, the voltage supply of the transponder chip is interrupted.
  • the fixed reading unit which is inductively coupled to the conductor coil in the webbing, can then read out any individual identifier.
  • the disadvantage here is that in case of a missing identifier is not clear whether the stationary reading unit, the transponder or one of the coils used for data transmission is defective.
  • the present invention seeks to show a device for detecting a hazardous condition of a band-shaped load carrier with embedded in the load carriers transponders, which is installable with little manufacturing effort in the band-shaped load carrier and If necessary, can be replaced with relatively little effort. Furthermore, a method for determining a hazardous condition of a band-shaped load carrier to be embedded in the load carriers embedded transponders, in which a reliable inference to damage the band-shaped load carrier is possible.
  • a device which achieves this object is the subject of claim 1.
  • the device according to the invention serves to detect a hazardous condition of a band-shaped load carrier, usually a conveyor belt.
  • This transport belt has at least one embedded transponder.

  • EP 0716 992 A2 in which only checks whether a transponder signal can be received or not, the transponder is read out in any case in the invention.
  • Whether a fault, i. a belt tear in the region of the conductor connected to the transponder, is present, can be determined on the basis of the states at the signal inputs of the transponder.
  • a break in the conductor would result in a potential difference between the first and the second signal input resulting in a change in the variable data leads.
  • This change in the variable data of the transponder indicates the crack in the belt-shaped load carrier.
  • transponder has fixed-code data for the unchangeable identifier and additionally variable data depending on the state at the at least one signal input.
  • a power source is arranged on the band-shaped load carrier.
  • the power source is not stationary, but moves together with the band-shaped load carrier.
  • the power source is connected via an electrical conductor to a signal input of the transponder.
  • This electrical conductor is important because the distance between the transponder and the power source, that is, the distance that is bridged between these two components, that is, the distance that is covered by the conductor, is the area that is active the device according to the invention is monitored. The monitoring takes place by means of an evaluation device connected to the receiving device. It is intended to evaluate the state of the said signal input of the transponder. In other words, it is checked whether the electrical conductor, which is galvanically connected to the signal input, transmits the electrical signal originating from the current source to the transponder.
  • the transponder has at least one signal input, so that a bit associated with the signal input is set depending on the state of the electrical conductor or the current source. This state is transmitted from the transponder to the receiving device and evaluated in the evaluation device. If the conductor is damaged, the corresponding bit is not set or the signal at the signal input is missing, the probability is very high that the electrical conductor is damaged. Therefore, the variable data of the transponder are read out in addition to a fixed identification of the transponder, in total therefore the individual information of the transponder.
  • the electrical conductor is the largest component in terms of area of the component arranged on the band-shaped load carrier.
  • the transponder and the power source are comparatively small.
  • the transponder has a size of about 2 to 3 cm 2 including the associated antenna. It is the same with the power source.
  • the electrical conductor is single or multi-core.
  • a special Advantage of this small size is that the transponder including the conductor and the power source require little space within the band-shaped load carrier and can be easily replaced due to this fact. Unlike large-scale induction coils, it is much easier in the invention to replace only one electrical conductor.
  • the conductor is preferably a non-looped line so that it can be removed by a minimal engagement on the band-shaped load carrier. In the same way new transponder, power sources and electrical conductors can be easily, inexpensively and quickly introduced into the band-shaped load carrier.
  • a stationary coupling unit serves to couple energy electromagnetically into the power source.
  • the current source which may be arranged remote from the transponder in one embodiment of the invention, is preferably formed by a coil, wherein a stationary coupling unit serves to inductively couple in electrical energy.
  • the power source itself is therefore not necessarily permanently intended to conduct energy to the signal input of the transponder. It is sufficient if the electrical signal is present only when the transponder is read out. For this purpose, it is necessary to synchronize the timing of the coupling of the electrical energy in the power source with the time of reading the receiving device.
  • the coupling unit and the receiving unit are therefore positioned in coordination with the positions of the current source or of the transponder.
  • a power source as an energy storage. It is conceivable that the electromagnetically coupled, electrical energy is stored for a certain period of time to increase the time window for reading the transponder. However, this is only a short-term storage. Alternatively, a battery can be used as a long-term power source. A battery, such as a button cell, has a limited life and is replaced from time to time to ensure its function. Also conceivable is the use of rechargeable memories, such as accumulators. The charging of the batteries can be done inductively. The transmission of an electrical signal from the power source to the transponder means a charge shift. This is only possible if there is a potential gradient.
  • the electrical conductor forms the first part of a circuit between the transponder and the power source.
  • the second part of the circuit can be formed by the material of the band-shaped load carrier itself.
  • the return path of the circuit is usually very high impedance.
  • the second part of the circuit between the transponder and the power source is formed by the electrical conductor, but also that the second part is formed by an electrical conductor.
  • This second electrical conductor can run parallel to the first electrical conductor. In other words, it may be a two-wire connection between the transponder and the power source.
  • the second electrical conductor is arranged at a distance from the first electrical conductor.
  • the first electrical conductor is arranged in or adjacent to a support layer of the band-shaped load carrier and the second electrical conductor in or adjacent a running layer which is arranged on the side facing away from the support layer of the band-shaped load carrier.
  • the two electrical conductors do not form a coil whose passage plane is parallel to the top and bottom of the load carrier.
  • the two electrical conductors are in a cross-sectional plane perpendicular to the direction of movement of the load carrier.
  • the electrical conductors which merely serve for signal transmission from the power source to the transponder, themselves form a coil.
  • the electrical conductors only have the function of signal transmission. The reading out of the signal and the signal evaluation takes place exclusively via the transponder.
  • the course of the electrical conductor can basically be chosen arbitrarily. It runs at least partially, preferably in total, perpendicular to the direction of movement of the band-shaped load carrier. In this way, almost the entire width of the band-shaped load carrier can be monitored. If the electrical conductor is damaged on its way between the power source and the transponder, no signal from the electrical conductor will be present at the transponder.
  • the evaluation unit interprets the information transmitted by the transponder accordingly so that the band-shaped load carrier is damaged in this area.
  • the at least one electrical conductor is arranged at least partially parallel to the direction of movement of the band-shaped load carrier. It preferably runs at a parallel distance of e.g. 5 to 15 mm from the longitudinal edges of the load carrier. With the invention, therefore, the longitudinal edges near areas of the band-shaped load carrier can be monitored. It is not necessary that the power source or the transponder is arranged at the band edge as well. These modules can be arranged at a slightly greater distance from the longitudinal edges of the load carrier. The actual monitoring should be done by the electrical conductor, which is brought for this purpose close to the longitudinal edges of the load carrier.
  • An advantage of the invention is that the structural changes of the band-shaped load carrier are very small.
  • the transponders should be as small as possible and also the electrical conductor, which is intended for the transmission of signals from and to the transponder, should also be small.
  • the coil connected galvanically to the integrated circuit of the transponder is surrounded by an omega-shaped antenna. This antenna is electromagnetically connected to the transponder.
  • the circular arc section of the omega-shaped antenna surrounds the transponder.
  • the Omega-shaped antenna facilitates the reading of the transponder and contributes significantly to the improvement of the signal transmission.
  • the antenna galvanically connected to the electronic circuit in particular in the form of a coil, can be very small be designed so that the transponder itself is easy and inexpensive to produce. It has a size of only a few millimeters.
  • the antenna can be made slightly larger. It can be formed for example by a spring wire.
  • the wire may have a thickness of 0.3 to 0.8 mm. Preferably, it has a thickness of 0.5 mm.
  • the data transmission between the transponder and the receiving device takes place in particular in the UHF range. These are frequencies of 0.3 to 3 GHz, in particular 800 to 1 000 MHz. This UHF range allows the use of very small transponders.
  • the inductive coupling of energy into the power source should take place in a frequency range deviating from the UHF.
  • the coupling of energy into the power source in the RF range up to 300 MHz, z. At frequencies around 13.8 MHz. It is essential that the two frequencies for data transmission and inductive coupling of energy do not influence each other.
  • the invention provides that the length of the electrical conductor between the transponder and the current source defines the monitored area.
  • the power source may e.g. be arranged in the vicinity of a first longitudinal edge of the band-shaped load carrier and the transponder in the vicinity of the other longitudinal edge. If the electrical conductor runs, for example, in a U-shape, so that the transponder is arranged in the running layer and the current source in the supporting layer, the transponder and the power source can also be arranged in the same longitudinal half of the band-shaped load carrier. In order to avoid overlays in relevant frequency ranges, different frequencies are selected, which differ in at least one power of ten.
  • transponder and power source are arranged on the same longitudinal edge, to the extent that transponder and power source form a component.
  • the spatial distance between these two components is less than the length of the electrical conductor.
  • the coupling unit can be an integral part of the receiving device.
  • the shape and design of the conductors may be identical for all three cases. The decisive factor is that a potential change occurs when the conductor is damaged and that the at least one conductor spans a sufficiently large area to be monitored.
