Systems and methods for controlling working fluid in hydraulic elevators
A hydraulic elevator may comprise a bidirectional pump that controls up and down motion of an elevator car. A VVVF drive may cause the bidirectional pump to provide working fluid in a controlled manner to a hydraulic jack that supports the elevator car. A control valve may be disposed between the bidirectional pump and the hydraulic jack so that the control valve can be closed when the elevator car needs to be held in place. To avoid pressure waves that propagate when the control valve is opened with disparate pressures on the pump and jack sides of the control valve, the bidirectional pump may adjust the pressure on the pump side of the closed control valve to the pressure on the jack side of the control valve before the control valve is opened.

A method for controlling elevator cars of an elevator system according to one example includes assigning free elevator cars of the elevator system to one of either general service or express priority service (EPS). A destination dispatch controller receives an express priority service (EPS) call. The EPS call can indicate a request for priority service from an EPS call originating location to an EPS call final destination. The controller can determine whether any active EPS assigned car can service the EPS call. A particular elevator car can be an active EPS car when the particular car is carrying out EPS service. When a specific active EPS car can service the EPS call, the controller assigns the specific EPS car to the EPS call. Upon completion of the EPS call, the controller unassigns the EPS car to a free car.

An elevator positioning system includes an optical tape, optical tape clips, and a sensor. The optical tape clips are resiliently biased and mount to various structures including mounting bracket that attach to elevator guide rails or other framework within the hoistway. A connecting member of the optical tape clips is configured to be disposed between a sensor and optical tape such that the sensor detects an interruption in the optical tape and can send signals to an elevator controller in response to detecting these interruptions. The position of the optical tape clips is such that the elevator car can be controlled to align evenly with the landings associated with the hoistway.
A hydraulic elevator system includes a power unit and elevator controller where the elevator car is controlled within the hoistway when a portion of the hoistway might be flooded. The power unit includes a water tight tank having a ventilation tube or snorkel. A moisture sensor is connected with the elevator controller, and positioned within the pit of the hoistway. The moisture sensor detects the existence of a flooded pit condition and communicates such a condition to the elevator controller. The elevator controller initiates a safety sequence when the presence of a flooded pit condition is detected to prevent the elevator car from entering a flooded area of the hoistway.

An elevator activation system provides virtual activation of one or more buttons by passengers. An optical sensor or time-of-flight camera is positioned near buttons of the elevator and projects an optical curtain over buttons of the elevator. Disturbances in the optical curtain are detected and an exact location of a disturbance in the optical curtain is communicated to a sensor controller which then virtually activates a button correlated to the particular location of the disturbance. The sensor controller communicates with an elevator controller such that the elevator is controlled based on the particular function activated in response to virtual activation of the button. The elevator activation system may further include a user feedback feature configured to signify to a passenger that a button has been virtually activated without physically contacting the button.
An elevator moves through a hoistway with one or more sensors positioned so that they pass by one or more targets that are in fixed positions relative to the hoistway. As they pass, an inductive current is generated, giving the elevator's control circuitry precise information as to the vertical position of the elevator car. The control system adjusts the raising and/or lowering of the elevator car based on that position information and any discrepancy between it and the supposed position at which the control system had believed the car was. Discrepancies are accumulated over time as an indication of cable stretch, and when the stretch exceeds a particular threshold, an alarm is raised for maintenance. The control system also defines a “door zone” around each landing where, based on the precise height measurement achieved herein, it is safe under the circumstances to open the doors of the car.

An elevator swing operation system for use in a building includes a plurality of floors with landings that are grouped into zones. The elevator cars are allocated to service the zones with a default allocation setup or configuration. The allocation of elevator cars to zones can be modified by moving an elevator car from one zone to another in response to a maximum estimated time to arrival being exceeded and a maximum number of elevator cars allowed to change zones not being exceeded. Furthermore, the default configuration or allocation can be restored when the system is in swing operation, an elevator car is parked, and a minimum time for receiving no calls has been exceeded.
