Definitions

  • the people counting device is a people counting device for an elevator with an elevator car with an entrance for determining the entry or exit of an elevator car by a person, with a presence sensor at the entrance of the elevator car for detecting the presence of a person in the area of the entrance or the passage of a person the input and for outputting a detection signal in the event of presence or passage, with an accelerometer on the elevator car, for detecting the vertical acceleration of the elevator car and for outputting positive and negative acceleration values based on the direction of movement of the elevator car upwards, and with an evaluation device which does this is designed to receive a series of current acceleration values for a certain period of time when receiving the detection signal and to analyze whether one of the acceleration values or the resulting movement profile exceeds an upper threshold or falls below a lower threshold and a signal for entering the elevator car by a To issue or process a person when the lower threshold value has been exceeded and to issue or process a signal for a person to leave the elevator car when the upper threshold value has been exceeded.
  • Entering means that a person moves from the space in front of the elevator car through the passage of the open elevator door into the elevator car. Leaving means that a person moves from inside the elevator car through the passage of the opened elevator door into the space in front of the elevator car.
  • the detection signal as well as the specific time period always occurs when the elevator car stops at a stop and when the elevator car door is open.
  • Positive acceleration values correspond to an acceleration of the elevator car upwards, i.e. towards the shaft head.
  • Negative acceleration values correspond to an acceleration of the elevator car downwards, i.e. towards the shaft pit.
  • the upper threshold value is a positive acceleration value.
  • the lower threshold is a negative acceleration value.
  • the evaluation device is preferably designed to sum the signals for entering to a value and to subtract the signals for leaving from the value and to output the value for the number of people in the elevator car and in particular the value after a certain period of time without a stop Set signal to zero.
  • the specific time period is preferably between 0.05 and 1 second, in particular between 0.1 and 0.5 seconds, in particular between 0.2 and 0.3 seconds.
  • the upper threshold value is at an acceleration between 0.001 g and 0.003 g or at an increase between 0.01 mm and 0.05 mm, and / or the lower threshold value at an acceleration between -0.001 g and -0.003 g or at a decrease between -0.01 mm and -0.05 mm.
  • the acceleration sensor is preferably attached to the presence sensor.
  • the presence sensor and the acceleration sensor preferably have the same carrier.
  • the presence sensor and the Accelerometer sensor has the same housing.
  • the evaluation device is preferably integrated in the presence sensor.
  • the presence sensor is preferably a light grid or a light barrier.
  • the evaluation device preferably has a device for wireless radio transmission.
  • Fig. 1 shows an acceleration diagram 10 for a person entering the elevator car.
  • the signal time is time 0 at the intersection of the time axis 11 with the acceleration axis 12.
  • a light barrier is attached to the elevator car doors and monitors the entrance to the elevator car.
  • An accelerometer for measuring the vertical acceleration and an evaluation device are integrated into the housing of the light barrier.
  • a person breaks the light barrier at the entrance to the elevator car to enter the elevator car.
  • the light barrier sends a detection signal to the evaluation device.
  • the evaluation device receives the detection signal. In the case of a persistent detection signal, only the start of the detection signal is relevant.
  • the start of reception of the detection signal is time 0.
  • the elevator control starts a timer until a certain period of time 24 has expired.
  • the evaluation devices receive values from the accelerometer. Values for the acceleration of the elevator car, which determine the course the acceleration curve 31 show.
  • the evaluation device analyzes the acceleration values and detects that at least one acceleration value falls below the lower threshold value 21 and sends a signal for a person entering the elevator car to a server via a radio device.
  • Fig. 2 shows an acceleration diagram 10 for a person leaving the elevator car according to Fig. 1 .
  • a person breaks the light barrier at the entrance to the elevator car to leave the elevator car.
  • the light barrier sends a detection signal to the evaluation device.
  • the evaluation device receives the detection signal. In the case of a persistent detection signal, only the start of the detection signal is relevant.
  • the start of reception of the detection signal is time 0.
  • the elevator control starts a timer until a certain period of time 24 has expired.
  • the evaluation devices receive values from the accelerometer values for the Acceleration of the elevator car, which shows the course of the acceleration curve 32.
  • the evaluation device analyzes the acceleration values and detects that at least one acceleration value exceeds the upper threshold value 23 and sends a signal for a person leaving the elevator car to a server via a radio device.
