Definitions

  • the invention relates to a procedure in which the brightness of signalling and the volume of sound signals are controlled on the basis of the background light and the noise in the environment.
  • the object of the present invention is to eliminate the present drawbacks and to achieve a considerable improvement in the convenience of use of an elevator.
  • the invention also aims at a simple and low-cost solution.
  • the invention is characterized by what is presented in the claims.
  • the sound volume is controlled by measuring the background noise level before the signalling.
  • the background noise level is high, the sound signal is issued with a higher volume, and similarly, when the background noise level is low, the sound signal is issued with a lower volume.
  • the output-signal obtained from a noise level measuring amplifier can be used directly for the volume control of the audio signal to be issued. It is important that the measurement is finished or that the result of the background noise measurement be locked or stored before the signalling to ensure that the signalling itself will not produce a change in the background noise level.
  • a brightness range or certain possible brightness values may be defined in advance and stored in a control unit, which adjusts the brightness on the basis of the measurement result.
  • a volume control unit measures the intensity of the background noise before the signalling, and if the background noise level is high, the sound signal is generated or delivered with a higher volume, and similarly, when the background noise level is low, the sound signal is issued with a lower volume.
  • the measurement result is produced by a noise level measuring unit.
  • Fig. 1 presents signalling devices controlled separately on each floor according to the prevailing external circumstances.
  • Figure 1 shows a signal device control unit in which the brightness of signalling and the volume of sound signals are controlled on the basis of the background light and the noise in the environment.
  • the control unit 1 controls signal devices 8, such as direction arrows and floor indicators, by means of signalling control signals 11 via a brightness control amplifier 5.
  • the brightness of the light signals given by the signal devices 8 is controlled by the brightness control amplifier 5 by means of a light sensor 2, an illuminance measuring amplifier 4 and a control range level signal 12.
  • a preset signalling control range level 12 determining the range of brightness variation of the signalling may be stored in the control unit 1.
  • the background noise is measured by means of a loudspeaker 3 of the sound signal device.
  • the loudspeaker 3 reacts to background noise like a microphone, i.e. it provides a signal proportional to the noise.
  • the signal obtained from the loudspeaker 3 is passed to a measuring amplifier 7, whose output is applied to the input of a variable-gain amplifier 6.
  • the control unit 1 locks the result of the noise level measurement by means of a locking signal 9 to ensure that the signalling itself will not produce a change in the measured background noise level.
  • the audio control amplifier 6 amplifies the audio signal according to the locked background noise level and a preset sound control range level 13.
  • the signal at the output of the audio control amplifier 6 is the larger the higher is the locked noise level.
  • the adjustment of the brightness of the signalling and the volume of the audio signal is performed in the control unit 1, in which case the output signals of the measuring amplifiers 4 and 7 are passed to the control unit 1.
