Definitions

  • the present invention relates to consumption detection systems with remote reading and especially on consumption recording systems, where planar antennas are used to emit a signal that is measured Consumption corresponds.
  • the electrical properties of the antenna types mentioned change very much as soon as conductive material, such as the housing of the meter, near the radiating component is coming. In professional circles, this effect is also called the “Proximity effect” called. This is how it works, for example a vertical antenna is only satisfactory if it is attached to the outside of the housing of the meter, the housing serves as an HF counterweight. So the antenna is from accessible from outside and can be easily damaged.
  • the wall mounting of such devices is fundamentally is a problem because there is a vertical antenna with it always close to the RF-disturbing house wall, for example can consist of reinforced concrete, or close to a metal radiator or gas meter.
  • the installation location also has the consequence that an omnidirectional characteristic of the transmitting / receiving antenna is not necessarily meaningful because of electrical energy is uselessly irradiated into the wall, which is fundamentally is lossy.
  • the linear polarization of the electromagnetic Field emitted by the antennas mentioned also has a disturbing effect, since it is reflected by electromagnetic waves Radiation to rotations of the plane of polarization the radiation that leads to a reduced reception power at the recipient's entrance.
  • DE-U-94 05 793 discloses a consumption distributor, in particular a heat cost or water cost allocator.
  • the electrical consumption distributor includes an antenna, which as an extending in the longitudinal direction of the consumption distributor elongated electrically conductive part formed is.
  • the antenna is at one end with the electrical Output of a circuit arrangement arranged adjacent to this end connected to a UHF transmitter while the other end of the same is kept electrically insulated.
  • the Antenna is designed as a wire bracket, the outside of one Housing of the heat cost allocator is arranged. Further Options for the execution of the antenna are the Wire bracket as a metallic decorative strip on the side Form upper housing part.
  • the antenna can be completely or partially in a side wall of the upper housing part the production of this part in a plastic molding process be molded in.
  • strips or wire brackets have the disadvantage that it is extremely difficult to work with such antenna shapes wireless metering requirements to fulfill.
  • linear dipole antennas have the problem is that they have an omnidirectional pattern have, which is why electrical energy is useless in one Wall, which is always lossy, is irradiated.
  • the linear polarization of the electromagnetic acts Field of a linear dipole antenna as well annoying because it is reflected by the electromagnetic Radiation to rotations of the polarization plane of the radiation comes to a reduced reception power at the entrance of the recipient.
  • US-A-5,181,025 discloses an adaptable telemetry housing, which comprises a complete system which Sensors, data acquisition components, one controller, one Has RF transmitter, an antenna and a battery.
  • the Antenna can be used in particular as a printed circuit antenna, such as B. a microstrip patch antenna.
  • the adaptable telemetry housing is with an adhesive coated, which allows the system to be such as B. the front edge of an airfoil Aircraft is attached.
  • the housing has an integrated Sensor, which is typically a temperature, a voltage, a current, a light, a pressure, a Magnetic, a vibration, an acceleration, or a Airflow sensor can be. This sensor is used in areas attached, which difficult to provide with measuring equipment can be such. B. on the surface of a Wing or aur the surface of ammunition.
  • the object of the present invention is a reliable wireless consumption recording system too create.
  • This task is performed by a consumption recording system Claim 1 solved.
  • the invention is based on the knowledge that it is Use a planar antenna in a consumption recording system is possible, the existing in the prior art Eliminate disadvantages. In particular, it enables the present Invention, the antenna in such a way in a consumption recording system to place that same from destruction and manipulation is safe.
  • Another advantage of the invention is that the metal housing of a consumption detection device the radiation pattern the planar antenna is not negative, but in the sense of better HF radiation is positively influenced, furthermore the radiation characteristic is directed away from the wall. Because of the fact that the planar antenna used in the invention emits elliptically polarized reflections along the radio link compared to linear radiators too much less power loss at the receiver.
  • the antenna used reacts relatively insensitive to an exact installation position and to a bad connection of the RF ground of the transmitter with the metallic housing of the meter, which is why in the design a consumption recording device not specifically for Position of the antennas must be taken into account, or on the other hand, a subsequent installation of the antenna without further is possible.
  • FIG. 1 shows a consumption recording system 10 which is connected to a Wall 12 is attached.
  • An embodiment of the present The invention is described with the aid of a gas meter. However, it is evident that the consumption tracking system according to the present invention also a water meter, can be a heat meter and the like.
  • a metallic gas meter housing 14 is on the wall 12 opposite side through a housing cover 16 Plastic finished. The housing cover is usually 16 with a seal to prevent unauthorized persons Avoid tampering with the gas meter.
  • On the housing cover 16 is a planar antenna 18 using adhesive or other suitable holding devices attached. The Planar antenna 18 is connected via a coaxial line 20 from one Radio module 22 fed.
  • the radio module is equipped with a gas meter device (not shown) in connection to the detected Gas meter reading suitable to process and in over the To convert planar antenna 18 emittable data signals.
  • the Gas meter device is located in the gas meter housing 14. It is obvious to experts that any other Consumption detection device connected to the radio module 22 can be so that the same over the planar antenna 18 can supply the coaxial cable with suitable transmission data.
  • Fig. 2 shows one in a preferred embodiment of the present invention used planar antenna 18 which is realized as an "inverted F antenna".
  • planar antenna 18 which is realized as an "inverted F antenna”.
  • Such antennas are described in K. Hirasawa and M. Haiishi “Analysis, Design, and Measurement of small and low profile antennas ", Artech House, Boston, London, 1992. Basically you can Planar antennas as stripline resonators with Radiation losses can be understood, the radiation losses of the resonator represent the radiated useful signal.
  • the “inverted F antenna” 18 is composed of the following components together. Located on a metallized base 26 dielectric antenna substrate 28, e.g. FR4. There is a metallized antenna surface on the antenna substrate 30 formed for example by known etching processes.
  • the antenna 18 is tuned the length of a short circuit strip 34 resonates at desired transmission frequency, e.g. 433 MHz, tuned.
  • FIG. 3 Another embodiment of the consumption recording system in accordance with the present invention is shown in FIG. 3.
