Method for operating a person separation device as well as person separation device

A method for operating a person separation device comprising a clearing system with at least one clearing area, a tracking unit and at least one automatic door system, the automatic door system comprising a door, at least one drive unit for actuating the door, a camera and a control unit for controlling the drive unit, wherein the field of view of the camera includes the clearing area wherein the method comprises the following steps:

• capturing a recording by the camera and transmitting the recording to the tracking unit, wherein at least one person is present in the recording,
• receiving, by the tracking unit from the cleaning system, the result of a clearing process of the at least one person in the clearing area,
• setting a clearing status of the at least one person based on the result of the clearing process of the respective at least one person by the tracking unit,
• tracking the movement of the at least one person in the recording after the cleaning process by the tracking unit, and
• controlling the drive unit based on the movement of the at least one person and the clearing status,
• wherein the drive unit is controlled to open the door for a specific person if the specific person approaches the door the clearing status of the specific person is positive and at least one security condition is met, or wherein the door is kept close or the drive unit is controlled to close the door if the specific person approaches the door but the clearing status of the specific person is negative or at least one security condition is not met,
• wherein the at least one security condition comprises the integrity of a door-related security zone, the door-related security zone being an area in the recording, wherein the shape and/or size of the door-related security zone depends on kinematic properties of an uncleared person including one or more of a walking speed, a walking direction of the uncleared person and a distance from the uncleared person to the door, wherein the security condition regarding the integrity of the door-related security zone is met if no uncleared person is within the door-related security zone,
• wherein the at least one security condition further comprises the integrity of a dynamic, personal security zone around the specific person, the personal security zone being an area with predefined shape and size in the recording around the specific person, wherein the security condition regarding the integrity of the dynamic security zone is met if no uncleared person is within the dynamic security zone,
• wherein the shape and/or size of the door-related security zone or the shape and/or size of the dynamic security zone is chosen such that the door can safely be closed between a cleared person (P) passing the door and an uncleared person (I) trailing the cleared person (P), and wherein the size of the door-related security zone or the size of the dynamic security zone depend on the current width of the opened passage of the door.
