Provided is an elevator monitoring system, including a gateway device, a load weighing device and an elevator controller; the elevator controller is configured to collect status information of an elevator car and fault information when an elevator fails; the gateway device is configured to obtain fault information and status information from the elevator controller; the load weighing device monitors current load value of the elevator car in real time and transmits the current load value to the gateway device; the gateway device calculates a minimum reference load value corresponding to each stopping floor level of the elevator car based on the current load value, updates and records the minimum reference load value in real time; based on the fault information and the status information, if the gateway device determines that the current load value is greater than the minimum reference load value, the gateway device will send a warning alarm.

A method of operating an elevator, the elevator having an elevator car, a motor, a controller and a counterweight (CW), the method including, for ascending of the elevator car when loaded with passengers, providing a car occupancy limiter (COL) and activating the COL by the controller for ensuring that the loaded car weighs less than the CW and controlling by the controller of the motor to not use motor rotational power; and for descending of the elevator car when loaded with passengers, where the loaded car weighs more than the CW, controlling by the controller of the motor to not use motor rotational power.

An energy-saving elevator. The energy-saving elevator includes an elevator car, a counterweight, a lift cable, and a hoist-type lifting mechanism. The hoist-type lifting mechanism includes a first adjustable pulley, a second adjustable pulley, and an adjustable cable interconnected between the first adjustable pulley and the second adjustable pulley. The first adjustable pulley includes a first fixed conical member with a first conical surface and a first moveable conical member with a second conical surface. The first conical surface and the second conical surface form a first trapezoid-shape groove between the first fixed conical member and the first moveable conical member. The first trapezoid-shape groove is configured to receive the adjusting cable. The first conical surface and the second conical surface are configured to hold the adjusting cable inside the first trapezoid-shape groove.

An elevator system is provided and includes a sensor assembly and a controller. The sensor assembly is disposable in or proximate to an elevator lobby and is configured to deduce an intent of an individual in the elevator lobby to board one of one or more elevators and to issue a call signal in response to deducing the intent of the individual to board the one of the elevators. The controller is configured to receive the call signal issued by the sensor assembly and to assign one or more of the elevators to serve the call signal at the elevator lobby.

A shuttle elevator loading system includes a plurality of shuttle elevators configured to service a building lobby. At least one sensor is configured to detect at least one passenger and at least one display unit is located at a display zone of the lobby. An elevator system controller is in signal communication with the at least one sensor and the at least one display unit. The elevator system controller determines a number of allocated passengers corresponding to each shuttle elevator and generates assignment information that directs a non-allocated passenger to an available shuttle elevator.

A robot may include a driving motor, a communication interface configured to communicate with an elevator control device, at least one sensor configured to sense an internal space of an elevator and a processor configured to determine whether boarding on the elevator is possible based on data received from the elevator control device or sensing data of the at least one sensor, set a boarding position based on information on the internal space of the elevator obtained through the communication interface or the at least one sensor when the boarding on the elevator is possible, and control the driving motor to move to the set boarding position.

An elevator system is provided. The system comprises a first acquisition unit that acquires an image in a car of an elevator and an image of a landing of the elevator; a first generation unit that generates first learning data from the acquired images; a learning unit that performs learning using the first learning data, thereby generating a first learned model; a second generation unit that generates input data from a new image; an estimation unit that estimates, by applying the input data to the first learned model, whether the person on the landing of the elevator, which is included in the new image, gets in the elevator; and a control unit that controls an operation of the elevator based on an estimation result.

A self-contained data acquisition system for a passenger conveyance system, includes a sensor module for sensing data associated with an entry and exit of each of a multiple of passengers, a location sensor module for sensing a position of the passenger conveyance upon entry and exit of each of the multiple of respective passengers and a processing module operable to use the sensed data from the sensor module and the location sensor module to record passenger data.

A method of controlling operation of an elevator system (2), the elevator system (2) including a hoistway (4) extending between a plurality of landings (8) situated on different floors (9), and at least one elevator car (6) configured for moving along the hoistway (4) between the plurality of landings (8). The method includes receiving a control input indicating a passenger transport request, wherein the control input comprises at least one passenger transport request parameter; monitoring passengers (30) within or outside the elevator car (6) and determining at least one passenger parameter associated with the passengers (30); comparing the at least one passenger transport request parameter with the at least one passenger parameter; and controlling further operation of the elevator system (2) based on the result of said comparison.

An object of the invention is to provide a vibration damping system that can avoid the occurrence of resonance of an elevator rope regardless of the vibration frequency of a vibration source. A vibration damping system (200) includes a displacement amplifier (7), a calculation unit (66), and a displacement amplification control unit (67). The displacement amplifier (7) is arranged along a given position in the longitudinal direction of the elevator rope. The displacement amplifier (7) amplifies a displacement due to vibration of the elevator rope based on a variable amplification factor. The calculation unit (66) calculates the natural frequency of the elevator rope. The displacement amplification control unit (67) controls the displacement amplification of the displacement amplifier (7) based on the natural frequency calculated by the calculation unit (66) and a preset vibration frequency.
