Embodiments of systems and methods for digital control of elevator and other access gateways are described herein. More specifically, embodiments comprise systems and methods for retrofitting or outfitting elevator systems with digital control systems that can be universally applied to virtually every manufacturer's elevator systems.

A story monitoring method when a robot takes an elevator is provided. The method including: obtaining gravity acceleration of the robot in a static state in an elevator and transient acceleration of the robot in a moving state in the elevator, a starting story number, and a story height of each story; obtaining an acceleration change waveform of the robot; comparing the acceleration change waveform by using an acceleration waveform classifier of the elevator, to obtain a movement status of the elevator at each moment; obtaining actual displacement of the elevator in a complete movement status of the elevator; and obtaining a story that the elevator is on after a complete movement status according to the actual displacement of the elevator, the starting story number, and the story height of each story.

An elevator includes a drive, a car operatively connected to the drive to traverse along a travel path, at least one guide rail positioned along the travel path to guide the car, a safety brake arranged on the car to exert a braking force on the guide rail, and a safety system. The safety system includes a first safety control unit and a second safety control unit that monitor a safety condition of the elevator. The first safety control unit outputs a stop signal to the drive, in particular to a drive brake and/or to a frequency converter of the drive, and the second safety control unit outputs a trigger signal to the safety brake to bring the elevator into a proper safety condition when an impermissible safety condition of the elevator is detected.

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.

Various embodiments are directed to an elevator positioning system, comprising: a transceiver disposed within an elevator shaft; a first positioning element; a second positioning element; and a controller communicably coupled to the transceiver, wherein the controller is configured to: determine a first distance between the transceiver and the first positioning element; determine a calibration distance between the transceiver and the second positioning element based at least in part on a second reflection detected by the transceiver from the second positioning element at a first instance; based at least in part on the first distance and the calibration distance, calculate an adjusted elevator car position defined at least in part by a shaft displacement compensation distance; and cause an elevator car to move about a vertical axis of the elevator shaft to a vertical position within the elevator shaft that corresponds at least in part to the adjusted elevator car position.

An elevator car location sensing system includes at least one first barometric pressure sensor disposed at a sensor position. The first barometric pressure sensor is configured to measure at least one first barometric pressure at the sensor position. An elevator control module is configured to electrically communicate with at least one mobile terminal device that is movable among a plurality of different altitudes. The elevator control module receives a second barometric pressure from the mobile terminal device located at a current altitude, and determines the current altitude based on a comparison between the first barometric pressure and the second barometric pressure.

An elevator control apparatus that can estimate an error of a governor encoder caused by expansion and contraction of a governor rope without need to add new governor speed detectors. The elevator control apparatus includes: a governor rope expansion/contraction amount estimating device that estimates an error of a governor encoder caused by expansion and contraction of a governor rope on the basis of a governor encoder counter signal according to a rotation of a governor around which the governor rope connected to a car of an elevator provided in a building is wound, when a landing plate detector of the car is switched from a state in which a landing plate provided at a position corresponding to a floor of the building is detected to a state in which the landing plate is not detected.

In order to be able to increase safety in elevator systems, a connecting device for connecting a transmission device for transmitting information is provided, wherein the transmission device is attached to a measurement tape for determining the position of a cab in an elevator shaft and wherein the connecting device is designed as a guide bracket for guiding and/or supporting the measurement tape, so that the guide bracket at least partially surrounds the measurement tape, and wherein the guide bracket has at least one opening for reading out the marking unit, and wherein the connecting device has two connection contacts for connecting to one of the communication lines and/or supply lines and an interruption device for interrupting one of the communication lines and/or supply lines, wherein the interruption device is situated in such a way that the interruption occurs between the two connection contacts.

An illustrative example method of controlling an elevator situated in a hoistway of a building includes detecting sway of the building, determining characteristics of the detected sway including a plurality of frequencies and associated periods of the sway, determining an expected sway of an elongated member of the elevator system based on the determined characteristics, and controlling at least one of position and movement of an elevator car in the hoistway based on the expected sway.

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.
