A landing floor door access system for an elevator system includes a door lock operably connected to a landing floor door, and a door lock controller operably connected to the door lock. The door lock controller is configured for non-contact communication with an access device such that communication between the access device and the door lock controller initiates a signal from the door lock controller to the door lock to deactivate the door lock. A method of accessing a hoistway of an elevator system, includes approaching a landing floor door of the elevator system, the landing floor door positioned at the hoistway, and initiating communication between an access device and a door lock of the landing floor door via non-contact interaction between the access device and the door lock. The door lock is deactivated via the non-contact interaction between the access device and the door lock.

A method of controlling access to a building is provided. The method comprising: receiving visitor contact information for a visitor from a resident device, the visitor contact information identifies a visitor device of the visitor; receiving visitor access permissions for the visitor from the resident device, the visitor access permissions include at least one of a selected elevator car, a selected door, and a selected floor; and granting the visitor device access to at least one of the selected elevator car, the selected door, and the selected floor.

An elevator system includes an elevator car that is movable in an elevator shaft. The elevator car has a car door, a car door drive for closing and/or opening the car door, and a car door control unit directly controlling the car door drive. A shaft door is provided on each door opening of the elevator shaft. Each shaft door has a shaft door drive for closing and/or opening the shaft door and a shaft door control unit directly controlling the shaft door drive. The car door control unit and the shaft door control unit are connected, preferably wirelessly, via a communication connection to open and/or close the shaft door and the car door synchronously.

An elevator system includes: a car traveling in an elevator shaft; a car door arranged on the car; at least one shaft door arranged on a door opening of the elevator shaft; a shaft door locking device, in particular comprising a shaft door drive, for unlocking and/or closing and/or opening the shaft door; a shaft door sensor arranged on the shaft door and a car door signal transmitter arranged on the car door; and a shaft door control unit operatively connected to the shaft door sensor, the shaft door control unit directly actuating the shaft door locking device when a car door signal of the car door signal transmitter is received by the shaft door sensor.

A hoistway door locking system includes an elevator shaft. Also included is an elevator car disposed within the elevator shaft and moveable therein between a plurality of access openings located at a plurality of levels of the elevator shaft. Further included is a plurality of locking mechanisms, at least one of the plurality of locking mechanisms being located at each of the plurality of access openings, wherein each of the plurality of locking mechanisms is operable between a locked condition and an unlocked condition, and wherein only a single locking mechanism may be in the unlocked condition at a specific time, the unlocked condition occurring upon alignment of the elevator car and the respective access opening having the single locking mechanism.

Elevator access systems having an access control module operably connected to an elevator system and an access device located within the access control module and removable therefrom, wherein when the access device is within the access control module a normal mode of operation of the elevator system is activated and when the access device is removed from the access control module, the elevator system enters a safety mode of operation.

A locking system that locks and unlocks a door of an elevator car travelling along a track having stopping points and associated stopping point zones includes a lock mechanism having a locking position wherein the door is immobilized in a closed position and an unlocking position wherein the door can be opened, an actuator for bringing the lock mechanism into the locking and unlocking positions, and a control device activating the actuator to bring the lock mechanism into the unlocking position when the car is located in the region of a stopping point zone. A position detecting unit continuously detects the position of the car relative to the track and communicates the position to the control device that continuously detects whether the car is located in the region of a stopping point zone by comparing the communicated car position to stored position limit values of the stopping point zones.

Disclosed is an elevator control system configured to control movement of an elevator car (12) along an elevator hoistway (26) between a starting position and a destination position (L2), the control system comprising a car holding position monitoring unit configured to monitor whether the elevator car (12) has moved upwards or downwards in the hoistway (26) during a holding period (68) where the car (12) was intended to remain stationary at the destination position (L2). The car holding position monitoring unit is configured to: Receive a first trigger signal (62) from a first car position reference system (40); upon receipt of the first trigger signal, receive signals from a further car position reference system to detect a first indicator (66) indicative of a travel distance (X2) between the position of the elevator car (12) in the hoistway (26) when receiving the first trigger signal (62) and the position of the elevator car (12) in the hoistway (26) when stopping at the destination position (L2); upon receipt of a further service call for the elevator car (12), receive further signals from the further car position reference system and receive a second trigger signal (70A) from the first car position reference system (40) to detect a second indicator (74A) indicative of a travel distance between the position of the elevator car (12) in the hoistway (26) at the end of the holding period (68) and the position of the elevator car (12) in the hoistway (26) when the elevator car (12) receives the second trigger signal (72A) from the first car position reference system (40); and detect whether the elevator car (12) has moved during the holding period (68) based on a comparison of the first indicator (66) and the second indicator (74A).

A method of controlling building systems is provided. The method comprising: detecting a status parameter of an elevator door; and displaying the status parameter of the elevator door on a device.

A method of controlling access to a building is provided. The method comprising: receiving visitor contact information for a visitor from a resident device, the visitor contact information identifies a visitor device of the visitor; receiving visitor access permissions for the visitor from the resident device, the visitor access permissions include at least one of a selected elevator car, a selected door, and a selected floor; and granting the visitor device access to at least one of the selected elevator car, the selected door, and the selected floor.
