Definitions

  • the invention relates to a disposal container, comprising a radio data transmission module with an antenna for transmitting data.
  • the CH 689 123 A5 discloses a method for detecting the level of distributed over an area established bulk, garbage or recyclable containers, especially for glass or paper, where there are several distributed over a region set up recyclables containers that are either individually or in groups , Each recyclable container is equipped with a level sensor and connected to a central unit via a radio link.
  • the containers of a container group on the parking spaces can be connected via radio to a data concentrator, which in turn is connected via a radio link to the control center.
  • the data concentrator, the material container and the center each have an antenna.
  • the DE 43 36 334 C1 (Aerospace AG) discloses a computerized recycling bin which automatically requests its emptying from external sources of energy at the central disposal site. In the process can be sent and received by a municipal utility with a computer and an antenna running or if necessary radio signals. The received signals come from the collection containers. The emitted signals are intended primarily for communication with transport vehicles, but may also be directed to collection container.
  • the collecting container comprises a filling level sensor.
  • the collecting container comprises an integrated antenna, which can be designed as a stretched dipole or as a container lifting ring, so that wanton damage can be prevented.
  • the object of the invention is to provide a the aforementioned technical field associated disposal container with a transmitting device for data, which has a high efficiency and is also robust.
  • the disposal container comprises a metallic area, in which the antenna is designed as a slot antenna.
  • slot antennas are slits in very (ideally infinite) ground planes.
  • the physical structure as well as the resulting field line image are dual to that of a wire dipole, ie E (electric field strength) and H field (magnetic field strength) are reversed, ie a vertical slot results in a horizontally polarized omnidirectional antenna.
  • E electric field strength
  • H field magnetic field strength
  • Such a slot antenna without major shortening measures in the outer shell of the metallic portion of the disposal container, in particular in the metallic area of a commercial disposal container, for example, a disposal container 1 Brüco, or the like are admitted.
  • the base resistance of a ⁇ / 2 slot in a large area can be about 500 ⁇ in the middle; By moving the tap towards one side of the slot, adaptation, for example to a 50 ⁇ cable, can be achieved (distance from the edge approx. ⁇ / 20).
  • the flat surface that houses the slot can also be bent or closed to a tube (s. Fig. 2 ). The latter results in a tube slot radiator.
  • the diameter D can be quite small (eg ⁇ / 8, corresponds to 220 mm at 169 MHz).
  • the slot must then be longer than ⁇ / 2 (in the example mentioned 0.75l).
  • the width of the slot is less critical and may be as low as 10 mm at 169 MHz, for example.
  • Slot antennas of length ⁇ / 2 can be achieved by widening the ends, z. B. annular, electrically extend and resonate.
  • a slot in a small area such as in a ⁇ / 2 and 3/4 ⁇ length with a ⁇ / 2 slot is central to the face and parallel to the length of the surface
  • no omnidirectional In contrast to a vertical slot in an infinite surface, such a slot in a small area (such as in a ⁇ / 2 and 3/4 ⁇ length with a ⁇ / 2 slot is central to the face and parallel to the length of the surface) no omnidirectional. The reason is topological nature.
  • the edges of the conductive surface also each form a radiator, which together with the slot form an array (a group antenna).
  • a slit in a surface can be shielded on one side by putting a cavity, ie a closed cavity, over it.
  • the cavity may be formed as an open parallelepiped comprising a bottom coincident with the slot and having side walls of height ⁇ / 4. If the cavity has the right dimensions, the slot is not affected, except that it only radiates into a half-space and doubles the foot-point resistance at resonance.
  • the disposal containers can be used as collection containers for bulk goods, refuse or valuable materials such as glass, various metals, various plastics, paper, cardboard, textiles, batteries, chemicals and special waste, bulky waste, gypsum, wood, paints and varnishes, medicines, scrap tires, building rubble, Electrical appliances / electronics etc. may be provided.

  • the disposal containers can also be provided as collection containers for waste oil, etc.
  • the disposal containers can also be designed for household waste, organic waste, industrial waste, etc.
  • the disposal containers can also be designed as mobile refuse collection containers, for example four-wheeled or two-wheeled.
  • the metallic portion of the disposal container is sized and shaped so that a slot antenna can be formed thereon, that is, it is not compulsory for the entire disposal container to be formed of metal. It is sufficient if, for example, the outer skin, or even only a portion of the outer skin, such as the lid or a design element on the outer skin is designed as a metallic area.

  • the metallic region is formed as an outer shell of the disposal container.
  • a slot antenna can be formed on the disposal container in a simple and elegant way. Existing disposal containers, which already have a metallic outer skin, can thus be easily upgraded. For this purpose, a disposal container wall can be easily slotted. In a disposal container with a door or lid and a distance between the door or lid and the outer wall of the disposal container may be formed as a slot antenna, especially if the slot is sufficiently precise. However, it should be noted that the slot antenna can only be active when the door or the lid is closed.

  • slot lengths can be provided.
  • a radio frequency of 433 MHz or other frequencies may be provided. It is also conceivable to provide the disposal container with a plurality of slots of different lengths, so that it can be operated at different frequencies.

Accordingly, the filling of the gap between the slot 200 and the inner shield 201 of the disposal container 1 with a dielectric or conductive material will also have a great influence.
  • FIG. 8 represents the measured path loss of the vertical 169 MHz slot "VS" 200 versus a horizontal half wave dipole at 1.2 and 2.0 m height above ground, and a comparison with theoretical free space propagation at + 2dBi antenna gain “Ref” and with ring slot in the lid "DS".

  • the vertical slot 200 is thus comparable to a substantially lossless half-wave dipole.
  • the different course of the path losses at different heights of the measuring antenna can be a consequence of the differently acting (ground) reflections.
  • the 3 dB bandwidth in the transmission measurement is somewhat lower than would be expected on the basis of the reflection factor measurement, presumably because of the limited bandwidth of the measurement dipole.

  • FIG. 12 shows the adjustment of the vertical 169 MHz slot 200 with inner shield 201 with and without garbage bag retaining ring.
  • the greatest influence on the center frequency thus exerts the retaining ring for the garbage bag, since it forms a short-circuit ring and is located close to the unshielded uppermost quarter of the slot 200. With a good 1 MHz this influence can also be accepted.
  • the path loss of slot 200 with inner shield 201 against a horizontal half-wave dipole at a distance of 2 to 5 m hardly differs from that without inner shield 201, so the efficiency remains substantially unchanged.
  • the FIG. 13 shows that between the measured series of measured line losses of the vertical slot 200 with inner shield 201 and without inner shield 201 (in the figure with "with cavity” and “without cavity” marked) substantially coincide. With “Ref” the theoretical free space propagation at + 2dBi antenna gain is listed as a comparison.
  • the relative bandwidth of the 869 MHz slot 210 is substantially greater than that of the 169 MHz slot 200 both without and with internal shielding.
  • the suitably adapted frequency range extends with an inner shield of approximately 840 to 1130 MHz and is evident both in the adaptation (reflection factor ) as in transmission against a broadband antenna (LPDA or logarithmic periodic dipole antenna).
  • the most striking difference to the 169 MHz slot 200 is the influence of the interior in addition to the larger bandwidth: While for 169 MHz, the interior of the disposal container 1 is too small for the formation of resonance phenomena (he represents a waveguide well below the cutoff frequency) at 869 MHz numerous waveguide modes excited. This is most evident when one observes the reflection factor curve of the unshielded 869 MHz slot 210 and closes the door.
  • FIGS. 15 and 16 show the reflection factor curve with open ( FIG. 15 ) and closed ( FIG. 16 ) Door. A comparable picture also results in transmission measurements.
  • FIGS. 17 and 18 are the reflection factor curves of the vertical 869 MHz slot 210 with inner shielding 211 with open ( Fig. 17 ) and closed door ( Fig. 18 ) compared.
  • the inductance can be reduced and possibly the matching network eliminated by using a narrower slot, that is, narrower than 10mm.
  • the cables used 204, 214 are type Huber & Suhner K02252, which are about 50 cm long. However, basically any two-wire cable can be used. Instead of the printed circuit boards 203, 213, another device for fixing the electronic parts can be provided.
  • the slot width does not necessarily have to be 10 mm, but can also be optimized, for example, on the basis of empirical tests.
  • exactly one slot is typically provided for formation as a slot antenna.
  • disposal containers can be formed with a slot antenna, such as collection containers for recycling materials such as glass collection containers, aluminum storage, paper collection, waste oil collection and the like. These can be designed as Oberflur-, Halbunterflur-, underfloor or as a small or large container.
  • a disposal container which comprises an antenna substantially conforming to the disposal container and thereby has a high efficiency.
