in accordance with a determination that the door is in the open state, use the control signal (CS) to generate an alarm for alerting that the door is open; and
in accordance with a determination that the door is in the closed state, use the control signal (CS) to generate a maintenance signal (MS) for indicating a need for maintenance of the door.
4 . The door operation management system according to claim 1 , wherein the processing circuitry is further configured to cause the door operation management system to:
send the control signal (CS) to a door actuator device configured to close and/or open the door.
5 . The door operation management system according to claim 4 , wherein the processing circuitry is further configured to cause the door operation management system to:
determine, based on the at least first air pressure data ( 1 ap ) and the at least second air pressure data ( 2 ap ), a relative force applied onto the door, for controlling the door actuator device to close and/or open the door dependent on the relative force.
6 . The door operation management system according to claim 1 , wherein the door operation management system comprises a plurality of doors and each door is connected to the door operation management system via a communication network.
7 . The door operation management system according to claim 1 , wherein the control signal (CS) configured to be received by a facility management system for controlling the ventilation of the room.
8 . A method for controlling the operation of a door to a room, the method comprising:
obtaining at least a first air pressure data ( 1 ap ) based on an air pressure on the inside of the door;
obtaining at least a second air pressure data ( 2 ap ) based on the air pressure on the outside of the door, wherein a closed state the door seals or partially seals space on the inside of the from the space on the outside of the room;
determining at least a first air pressure difference data ( 1 apdd ) based on the difference between the at least first air pressure data ( 1 ap ) and the at least second air pressure data ( 2 ap ), and in a determination that the at least first air pressure difference data ( 1 apdd ) is outside of a predefined value, or a predefined value interval, generate a control signal (CS) for controlling the operation of the door; and
determining a total time, or a number of times, the door has been exposed to least one of the at least first air pressure data ( 1 ap ), the at least second air pressure ( 2 ap ) and the at least first air pressure difference data ( 1 apdd ), and in a determination that the total time, or the number of times, exceeds a predefined time value or a predefined number of times value, generate a maintenance signal (MS) for indicating a need for maintenance of the door.
