Definitions

  • the invention relates to a method for determining and/or checking a status of a door system. Furthermore, the invention relates to a status determination device for determining and/or checking a status of a door system, as well as such a system and a computer program product.
  • door devices and their subsystems or door systems typically suffer from signs of wear, which can be caused by the use of the door device, by the aging of the parts and components or by environmental influences. Such wear phenomena can depend on a variety of influences and can develop very differently and at different speeds.
  • various door systems of a door device can be affected by signs of wear, for example a drive unit of the door device or an electric lock. In principle, therefore, it is necessary to service door devices in order to identify and rectify signs of wear and defects.
  • the task arises of enabling the status of a door system to be determined and/or checked efficiently, so that the effort and costs for maintenance work and/or the downtimes can preferably be reduced.
  • this makes it possible to determine the status of a door system efficiently.
  • This makes it possible to keep data volumes low and still achieve an advantageous status determination. Overhead can thus be reduced and advantageous cost efficiency can be achieved.
  • the amount of data recorded and/or the amount of data transmitted between individual components of a system according to the invention can be kept small.
  • advantageous status monitoring can be achieved in this way, which enables improved planning for maintenance work. Efficient predictive maintenance can thus be achieved for a door system. In particular, unnecessary maintenance work by a specialist can be reduced or avoided. Both resources and costs can thus be saved.
  • the method according to the invention is in particular a computer-implemented method in which one, several or all steps of the method are executed in a computer-implemented manner.
  • a status of a door system can be determined and/or checked for a selectable period of time. It is conceivable that the steps of the method are carried out in different orders. It is conceivable that the steps of the procedure overlap in time.
  • the status determination step for determining and/or checking the status of the door system includes an analysis of the at least one item of measurement information using a model and/or an artificial intelligence system.
  • the sub-area comprises a contiguous area or two or more separate and spaced areas of the operating phase.
  • the measurement information is formed by numerical integration of measured values determined in the sub-area, relating to at least one measured variable, and/or control values, relating to at least one control variable.
  • the ascertained and/or checked status of the door system relates to or includes a wear status of a subsystem of the door system and/or a wear status of the entire door system.
  • a wear status can advantageously be determined and/or output, with the aid of which predictive maintenance can be implemented.
  • the at least one item of measurement information is determined using a measurement of a measurement variable of the door system by a measurement device, and/or that the at least one item of measurement information is determined by a control device setting and/or determining a control variable of the door system.
  • the control variable can also be understood as an adjustable variable for the door system, which is output and/or set by the control device, for example during operation of the door system, and with which the door system is controlled. If the door system is a drive unit of the door device, the control variable can be a drive voltage and/or one or more parameters of a pulse width modulation, for example.
  • the measured variable can also be understood as a measurable variable of the door system.
  • the at least one item of measurement information is determined only during the partial range of the operating phase of the door system.
  • the measurement information is preferably determined in such a way that the measurement variable of the door system is measured by the measurement device for generating the at least one measurement information only in the partial area.
  • the measurement information is preferably determined in such a way that the activation variable of the door system is determined by the control device for generating the at least one measurement information only in the partial area.
  • the measurement information is not determined during at least one further sub-area of the operating phase or that the measurement information is not determined during the entire operating phase outside of the sub-area. As a result, costs and energy can be saved and the amount of data generated can be kept low.
  • further measurement information in particular relating to the same measured variable and/or control variable as the measured information, is determined, the determination and/or checking of the status of the door system, in particular in the status determination step, being independent of the further measurement information, and/or the further measurement information being disregarded when determining and/or checking the status of the door system, in particular in the status determination step. It is therefore conceivable that the further measurement information has no influence on the determination and/or monitoring of the status of the door system.
  • measurement information relating to the measured variable and/or control variable is determined during the entire operating phase of the door system, in particular by determining a measured variable and/or setting and/or determining a control variable during the entire operating phase of the door system, with only the part of the measurement information determined in the sub-area of the operating phase, ie in particular the at least one measurement information, is used to determine and/or monitor the status of the door system. Measurement information ascertained outside of the relevant sub-area can thus particularly advantageously remain unconsidered when ascertaining the status.

  • a reversal area is particularly suitable for determining wear on the door system or on a subsystem of the door system, for example a gear.
  • such a reversal area can also be understood as a sub-area composed of a braking area and an approach area.
  • the backlash in such a reversal area is proportional to the wear of the door system or the subsystem of the door system.
  • the determined at least one piece of measurement information or the determined measurement information is a speed of a moving part of the motor and/or the transmission, in particular an angular velocity of a rotor of the motor and/or a gear wheel of the transmission, and/or a current and/or an actuating voltage of the motor of the drive unit.
