A pressurized fluid powered cabin-management system for an elevator system with a cabin and drive system is provided. The cabin-management system is configured to direct operation of the elevator system upon arrival of one of the cabins at a floor, and comprises a floor detector configured to detect when the cabin is located at a floor and to activate a timer. The timer is configured, when triggered, to activate a timing arrangement and to pass pressurized fluid to a control valve being in a first position. The timing arrangement is configured to direct the control valve to assume a second position after a predetermined amount of time. The cabin-management system performs, when pressurized fluid is passed to the control valve in its first position, actions for opening a door, and, after the control valve has assumed its second position, actions for travel of the cabin.

A car controller for an elevator car of an elevator system can be arranged on the elevator car. The car controller obtains a primary door opening request from an elevator controller of the elevator system, obtains at least one control signal, the at least one control signal indicating whether the elevator car is in a state intended for opening a car door of the elevator car, and transmits or withholds a secondary door opening request on the basis of the primary door opening request and the at least one control signal.

Systems and methods for protecting autonomous mobile machine tailgating may include an elevator control system that receives, from an autonomous mobile machine, an request signal requesting access by the autonomous mobile machine to a restricted floor of a facility. The elevator control system may also determine a presence of an individual in an elevator with the autonomous mobile machine. The elevator control system may perform a tailgate prevention operation to prevent an unauthorized access of the individual to the restricted floor by following the autonomous mobile machine. The elevator control system may also provide access for the autonomous mobile machine to exit the elevator at the restricted floor, in response to the tailgate prevention operation being performed.

The invention relates to a method for defining a tension of a belt of an automatic door. The method comprises: exciting a resonant frequency of the belt to cause a vibration of the belt, obtaining motion data representing motion of an electric motor configured to move the belt, defining vibration information representing the vibration of the belt based on the obtained motion data, and defining the tension of the belt based on the defined vibration in-formation and predefined characteristics of the belt. The invention relates also to a door drive unit and a computer program for defining a tension of a belt of an automatic door.

Vehicle parking information is used to control an elevator system. The vehicle parking information indicates that at least one parking space is occupied, and one or more elements of the elevator system may be controlled based on the vehicle parking information. An apparatus, a method and a computer program are provided.

A multi-car elevator control device that can shorten an open and close time of a door is provided. The multi-car elevator control device includes, in an elevator system including a plurality of cars that overlap each other on a horizontal projection plane, an open and close instruction judging part that changes, based on a motor speed or current in a moving time of a car door of a specified car, a control parameter of a car door of another car. According to the configuration, the multi-car elevator control device changes, based on the motor speed or current in the moving time of the car door of the specified car, the control parameter of the car door of the other car, in the elevator system including a plurality of cars that overlap each other on the horizontal projection plane. Therefore, the open and close time of the door can be shortened.

The present invention relates to a method of highly efficiently operating an elevator by analyzing an operation of the elevator, including: a base information collecting step of measuring and collecting information on a change over time in magnitudes of current values of a driving unit when the driving unit for moving the elevator upward or downward moves the elevator upward in a normal state, measuring and collecting information on a change over time in magnitudes of current values of the driving unit when moving the elevator downward, classifying the measured information into driving information of the driving unit when moving the elevator upward and driving information of the driving unit when moving the elevator downward, and storing the driving information of the driving unit when moving the elevator upward and the driving information of the driving unit when moving the elevator downward as base information of the driving unit.
