An apparatus for guiding a maintenance individual to perform a safety checking operation on a functional component of an elevator system includes: a wireless signal component connected with the elevator controller of the elevator system and establishing a wireless communication connection with the mobile terminal carried by the maintenance individual to enter the elevator hoistway for maintenance operation by broadcasting wireless signal; the apparatus configured to perform information interaction about the functional component by a wireless communication module of the mobile terminal and the elevator controller, and to provide safety checking guidance information for guiding the maintenance individual to complete the safety checking operation by a safety checking guidance module of the mobile terminal.

Guidance on safety inspection operations of functional component of elevator system

Acquisition of position information of an elevator car. The system for acquiring the position information of an elevator car of the invention comprises: a first Bluetooth module travelling in an up-down direction of an elevator hoistway following the elevator car, and a second Bluetooth module disposed in the elevator hoistway; wherein the second Bluetooth module broadcasts a Bluetooth signal containing an identifier of the second Bluetooth module to the elevator hoistway, and the first Bluetooth module senses signal strength information of the Bluetooth signal it receives and determines the identifier corresponding to the second Bluetooth module broadcasting the received Bluetooth signal; the system is configured to determine the position information of the elevator car according to received signal strength information of the Bluetooth signal and a corresponding identifier.

Acquisition of position of elevator car

An elevator calling operation based on a wrist-wearable smart device. An elevator calling operation system of the present invention comprises: an elevator control apparatus, and a wrist-wearable smart device wirelessly connected to the elevator control apparatus, wherein the wrist-wearable smart device comprises an identity identification module which stores identity identification information about a passenger, and a motion sensor which is used for acquiring elevator calling motion information about the passenger performing an elevator calling operation, and the wrist-wearable smart device transmits the elevator calling motion information, in association with the identity identification information, to the elevator control apparatus; and the elevator control apparatus comprises: a passenger identity recognition module and an elevator calling operation recognition module, the elevator calling operation recognition module used for recognizing the elevator calling operation of the passenger according to the elevator calling motion information from the motion sensor.

Elevator calling operation based on wrist wearable smart device

Methods and systems of controlling elevators including detecting a landing stop for an elevator car, measuring load information associated with the stop, controlling stopping of the elevator at the landing using a machine based on at least one of the detected landing and the measured load information and performing dynamic compensation control of a motion state of the elevator with a computing system and the elevator machine. The dynamic compensation control includes receiving motion state information related to at least one motion state of the elevator car at the computing system, receiving the landing and load information at the computing system, applying a filter to the received information and generating a first control signal, and producing a control output from the first control signal to control the elevator machine to minimize oscillations, vibrations, excessive position deflections, and/or bounce of the elevator car at the detected landing.

Dynamic compensation control for elevator systems

The present invention provides a damper of an elevator car, a control method of the damper, and an elevator system, belonging to the technical field of elevators. The damper of the present invention includes a base, a clamping mechanism mainly including two clamp arm components, a solenoid drive part, and a link transmission component, wherein the link transmission component is configured to be movable in a direction approximately perpendicular to a guide surface and drive at least one of the two clamp arm components connected thereto to move towards a guide rail. The control method of the present invention can enable the damper to work in a disengaged state, a slight contact state or a damping output state.

Stabilizing device of elevator car and a control method thereof, an elevator system

A stabilization apparatus of an elevator car includes: a base fixedly mounted with respect to the elevator car; an upper swing arm and a lower swing arm disposed in parallel basically, first ends thereof being pivotably fixed to the base; a guide rail friction member capable of generating, with the guide rail, a frictional force for keeping static with respect to the guide rail, and having a first connecting shaft and a second connecting shaft for being connected to the upper swing arm and the lower swing arm respectively; and a damper having at least one end connected to the upper swing arm or the lower swing arm, wherein the damper is configured to at least partially prevent the upper swing arm and the lower swing arm from relatively swinging, with the first connecting shaft and/or the second connecting shaft as a swinging pivot.

Stabilizing device of elevator car

A method includes receiving, by a computing device including a processor, a handwriting input including a selection of a destination floor associated with an elevator system, determining, by the computing device, that the handwriting input selection is recognizable, presenting, by the computing device, a message that requests confirmation that the input selection is interpreted correctly based on determining that the handwriting input selection is recognizable, receiving, by the computing device, a response to the message that confirms the input selection, and causing, by the computing device, the elevator system to provide access to the destination floor based on the response.
