Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • Such a device is known from European patent application 0 395 085 A1.
  • a high-frequency oscillation in the range of approximately 141 kHz plus / minus 4 kHz is generated by excitation of a resonator comprising a coil and a capacitor by a low-frequency pulse train signal, so that after each excitation of the resonator by a pulse train signal, a high-frequency, damped oscillation occurs whose amplitude drops to a value below 10% of the maximum amplitude of the oscillation during the duration of half a period of the pulse sequence signal.
  • the electromagnetic waves emitted by the coil act on the masonry without contact and dehumidify it.
  • the frequency of the high-frequency waves emitted by the coil of approx. 141 kHz from the parameters the coil and the capacitor in the resonator excited by a pulse to oscillate at the natural frequency are adjusted.
  • the design of the capacitor as a variable capacitor is proposed.
  • such an adjustment is relatively difficult since the fundamental frequency of a damped oscillation can only be measured with sufficient precision with a relatively high outlay.
  • the most exact setting possible is necessary since a good approximation to 141 KHz requires a significant optimization of the dehumidification effect.
  • the resonance frequency of the resonant circuit is not satisfactorily constant due to the influence of the air coil.
  • the device according to the invention enables the generation of alternating electromagnetic fields with a very precisely definable frequency. Influences on the high frequency of the alternating field or, in particular, in the case of sequences of wave trains which are damped in each case with an envelope curve, changes in the curve shape due to environmental influences in the region of the coil, such as electrically conductive metal parts, are significantly reduced when the device is designed in accordance with the invention. It is not necessary to adjust the device during commissioning.
  • the device according to the invention can be implemented with simple and inexpensive means. In particular due to the frequency-stable structure, it can be trained with good EMC (electromagnetic) compatibility.
  • the device can preferably be supplied with its supply voltage via an EMC-compatible standard power supply unit, since the entire device can be designed to be relatively easily EMC-compatible.
  • a frequency-stable oscillator is preferably used as the oscillator in order to avoid fluctuations in the frequency of the emitted electromagnetic fields.
  • a frequency divider which in turn is connected on the output side to a phase comparison for controlling the voltage-controlled oscillator is.
  • single or multiple mains voltage frequency is used as the reference frequency of the oscillator in order to achieve the simplest possible structure.
  • the coil is expediently designed as an air coil, since the permeability of air thus results in a suitable coil size when the coil is designed to emit high-frequency electromagnetic fields.
  • a modulator connected downstream of the oscillator is advantageous, by means of which sequences of wave trains each having an envelope curve of lower frequency than the high-frequency vibrations can be generated, since it has been shown that a combination of the high-frequency electromagnetic vibrations with low-frequency Vibrations, for example in the range of the fluctuation frequency of the earth's magnetic field from 7 to 15 Hz or the like have a positive influence on the dehumidification of the masonry.
  • the envelope can expediently be generated by a differentiator connected on the input side to low-frequency square-wave AC voltage, in particular consisting of a capacitor and a resistor, which results in a very simple construction.
  • the air coil can also be subjected to a low-frequency voltage in order to generate an alternating electromagnetic field with a high-frequency and low-frequency component.
  • FIG. 1 shows an electronic circuit for generating a high-frequency voltage U, which is applied to a coil L, which generates an alternating electromagnetic field E, which acts on a wall 1 which is distanced from the coil L and which is thereby dehumidified.
  • the circuit is acted upon by a power supply 2 with a supply voltage and with a low-frequency signal S1, which serves as a reference signal for the phase comparison 3.
  • VCO voltage-controll-oscillator
  • the VCO generates an extremely frequency-stable output signal S3 with preferably 141 kHz as precise as possible.
  • This high-frequency signal S3 is applied to the coil L, which generates a corresponding alternating electromagnetic field.
  • the signal S3 is forwarded to a frequency divider 4, which converts the high-frequency signal into a low-frequency signal S4, for example by means of a digital counter circuit with a frequency division factor.
  • the high-frequency signal S3 of 141 kHz with a frequency division factor of 1/1410 achieved by connecting a digital counter produces a low-frequency signal S4.
  • the phase comparison 3 is carried out with this signal S4 and the signal S1, which also has 100 Hz here, and the result of the phase comparison is used as signal S3 to control the VCO 6.
  • the oscillator 5 thus comprises a phase comparison 3, a VCO 6 and, moreover, a frequency divider 4 for generating a signal of the same frequency as the reference frequency.
  • the phase comparison and VCO components of the oscillator can be implemented on a standard module, for example.
  • FIG. 2 shows a further exemplary embodiment of the invention, which, in accordance with FIG. 1, comprises a power supply unit 2 and an oscillator 5 with a phase comparison 3, a frequency divider 4 and a VCO 6.
  • the signal S3 high-frequency at 141 kHz is modulated in a modulation unit connected downstream of the oscillator.
  • This creates sequences of wave trains, each with an envelope curve lower in frequency than the high-frequency signal S3.
  • the signal S4 which is approximately rectangular here, slides over a differentiator, here inform of an RC element, so that the signal S5 inform is generated by individual pulses which decrease exponentially here.
  • This signal S5 is used to modulate the high-frequency signal S3 in the modulator 7, so that a signal S6 is obtained which has high-frequency oscillations with envelopes informing the exponentially decaying individual pulses S5.
  • This signal S6 is applied to the coil L.
  • the modulation of the high-frequency signal with sequences of exponentially falling single-wave trains results in an Better electromagnetic compatibility compared to the high-frequency continuous signal.
  • the air coil L can additionally be supplied with a low-frequency signal, in this case a signal of 50 Hz generated by a frequency divider 8, via a switch 10.
  • the invention allows the very efficient dehumidification of masonry, in particular because of the high frequency stability achieved due to the use of an oscillator with a good efficiency.
