Abstract

A method for operating a door actuator of a door system, having at least one movable door leaf and a control device, which is designed to control the drive of the door leaf, and having a sensor unit, which is designed to detect at least one person in a region before the door system, and transmits information about the person to the control device, includes at least the following steps; a) detecting a person approaching the door system laterally, b) identifying a parameter set (P) having the distance (A) changing in time, the approach angle (□) and/or the speed (S) of the person relative to the door system, c) determining the desire to enter of the person approaching laterally on the basis of a comparison of the currently identified parameters with stored parameters and d) opening the door leaf only in the case of the determined desire to enter.

First claim

The invention claimed is:

1 . A method for operating a door actuator of a door system, having at least one movable door leaf and having a control device, which is designed to control the drive of the door leaf, and having a sensor unit, which is designed to detect at least one person in a region before the door system, and transmits information about the person to the control device, the method comprising the following steps:
a) detecting a person approaching the door system laterally, b) identifying a parameter set (P) comprising approach angle (a) of the person relative to the door system and/or speed(S) of the person relative to the door system, c) determining the desire to enter of the person approaching laterally on the basis of a comparison of the currently identified parameters with stored parameters, to which a desire to enter is assigned and stored, d) opening the door leaf only in the case of the determined desire to enter, and combining the plurality of parameter sets (P) including the approach angle and the speed(s) and correlating the parameter sets in order to generate new parameter sets for the door system.

2 . The method according to claim 1 ,
wherein the parameter set (P) identified in b) and linked with the desire to enter determined in c) are stored in a memory.

3 . The method according to claim 1 ,
wherein the stored parameters are identified on a self-learning and continuous basis by the parameter set (P) identified according to step b) being stored with the subsequent information as to whether or not the person has also actually passed the door system.

4 . The method according to claim 1 ,
wherein the parameter set (P) is determined by a person vector (V), which is formed from the speed (S) of the detected person, which represents the vector length, and which is determined from the approach angle (a) of the detected person, which represents the vector direction, wherein the person vector (V) changes in time during the approach time of the person to the door system, wherein the person vector (V) changing in time is stored in a memory.

5 . The method according to claim 1 ,
wherein the control device continuously over time:
detects a number of people,
identifies the respective parameter set (P), and
determines whether or not the people pass the door system, learns to derive a desire to enter of a person through the door system from the specific parameter set (P) and optimizes over time.

6 . The method according to claim 1 ,
wherein a number of movement vectors (V) is continuously stored in the memory linked with the information as to whether or not the person has also actually passed the door system.

7 . The method according to claim 1 ,
wherein the sensor unit is formed by a radar sensor or by a camera with an image processing module, wherein the sensor unit has a central main detection region (H) with a high detection signal, to which lateral areas (Z 1 , Z 2 ) adjoin in which a reduced detection signal is emitted by the sensor unit, wherein the method step c) is only carried out when the sensor unit detects the approach of a person from the lateral areas to the door system.

8 . The method according to claim 1 ,
wherein the memory is pre-programmed with parameter sets (P) and an assigned entry behavior.

9 . The method according to claim 1 ,
wherein the parameter sets (P) with the assigned entry behavior added over the service life of the door system are correlated with the pre-programmed parameter sets (P) and continuously expanded.

10 . A door actuation method for a door system comprising a control device for:
a) detecting a person approaching the door system laterally, b) identifying a parameter set (P) comprising approach angle (a) of the person relative to the door system and/or speed(S) of the person relative to the door system, c) determining the desire to enter of the person approaching laterally on the basis of a comparison of the currently identified parameters with stored parameters, to which a desire to enter is assigned and stored, d) opening the door leaf only in the case of the determined desire to enter, and combining the plurality of parameter sets (P) including the approach angle and the speed(s) and correlating the parameter sets in order to generate new parameter sets for the door system.

11 . A door system for carrying out a method for operating a door actuator of a door system, comprising at least one door leaf and at least one door actuator of the door system having a control device, the method including following steps:
a) detecting a person approaching the door system laterally, b) identifying a parameter set (P) comprising approach angle (a) of the person relative to the door system and/or speed (S) of the person relative to the door system, c) determining the desire to enter of the person approaching laterally on the basis of a comparison of the currently identified parameters with stored parameters, to which a desire to enter is assigned and stored, d) opening the door leaf only in the case of the determined desire to enter, and combining the plurality of parameter sets (P) including the approach angle and the speed(s) and correlating the parameter sets in order to generate new parameter sets for the door system.

12 . A non-transitory computer readable medium storing instructions for carrying out a method 1 for operating a door actuator of a door system and/or for operating the door actuator of the door system having a control device, the method including following steps:
a) detecting a person approaching the door system laterally,
b) identifying a parameter set (P) comprising approach angle (a) of the person relative to the door system and/or speed (S) of the person relative to the door system,
c) determining the desire to enter of the person approaching laterally on the basis of a comparison of the currently identified parameters with stored parameters, to which a desire to enter is assigned and stored,
d) opening the door leaf only in the case of the determined desire to enter, and combining the plurality of parameter sets (P) including the approach angle and the speed(s) and correlating the parameter sets in order to generate new parameter sets for the door system.
