Safety braking systems for elevators
Elevator safety brake and/or safety actuator health monitoring systems and methods including an elevator car moveable within an elevator shaft along a guide rail, and a first safety brake assembly arranged on the elevator car and configured to engage with the guide rail to provide emergency braking to the elevator car. The first brake assembly includes a first safety brake and an electronic safety actuator operably connected to the first safety brake. A health monitoring element is in communication with the electronic safety actuator. The health monitoring element is configured to record information associated with operation of the first safety brake assembly, compare the recorded information against at least one predetermined threshold, and when the recorded information exceeds the at least one predetermined threshold, generate a notification that maintenance is required.
System and method for maintenance of Shabbat elevators
A method for maintenance of an elevator in Shabbat mode, the method including providing a Shabbat elevator maintenance system, where the system is in communication with the elevator, detecting a malfunction in the elevator by the maintenance system, notifying a technician about the malfunction by the maintenance system, following repair of the elevator by a repairing technician, verifying by the maintenance system that the elevator has been repaired and that Shabbat mode has been reactivated, and activating remuneration for the repairing technician by the maintenance system.
Elevator cord health monitoring
A method of fault detection of a belt or rope includes connecting a fault detection unit to at least a portion of a belt or rope including a plurality of wires arranged in a plurality of strands and/or cords. At least the portion of the belt or rope is subjected to an AC voltage of high frequency range and an electrical impedance of the portion of the belt or rope is measured via the fault detection unit. Using at least the measured electrical impedance of the portion of the belt or rope, a fault condition of the belt or rope is determined.
BEAM CLIMBER ACTIVE BRAKE HEALTH MONITORING SYSTEM
An elevator system including: an elevator car configured to travel through an elevator shaft; a first guide beam extending vertically through the elevator shaft, the first guide beam including a first surface and a second surface opposite the first surface; a beam climber system configured to move the elevator car through the elevator shaft, the beam climber system including: a first wheel in contact with the first surface; and a first electric motor configured to rotate the first wheel; a first motor brake mechanically connected to the first electric motor, the first motor brake configured to slow the elevator car; and a brake condition based monitoring system configured to detect when the first motor brake is dragging.
AUTOMATIC FAULT CLEARING FOR ELEVATORS, ESCALATORS AND AUTOMATIC DOORS
A device and a method for controlling an apparatus being an elevator, an escalator or automatic doors are provided, by which it is detected whether a fault is present in the apparatus, it is determined, when the fault is present, whether an automatic fault clearing may be carried out, and if it is determined that the automatic fault clearing may be carried out, the automatic fault clearing is performed by automatically clearing one or more faults.
SYSTEM FOR THE GENERATION OF CALL ADVANCE DATA
A system for the generation of call advance data for an elevator control, which system is going to be installed in an elevator car moving in an elevator shaft and includes at least one acceleration sensor outputting current acceleration data and/or magnetometer outputting a magnetic flux signal which includes current magnetic flux data at the current position of the elevator car, which acceleration sensor and/or magnetometer is mounted in connection with the elevator car; a velocity calculating unit which calculates from the current acceleration/magnetic flux data current car velocity data; a position calculating unit which calculates from the current acceleration/magnetic flux data and/or from the current car velocity data current car position data; and a call advance processing unit which calculates from the current car velocity data and the current car position data call advance data which designates the time until which the car is able to stop at the next approaching floor in travelling direction, which call advance data is transmitted to a call allocation unit of an elevator control. Call advance data is provided in an easy manner without using existing car position detection devices of an existing elevator to be modernized.
DEVICE FOR CONNECTING A CONTROL DEVICE OF A PASSENGER-CONVEYING SYSTEM
A device for connecting a control device of a passenger transport installation to a communication unit for transmitting data to an entity remote from the passenger transport installation includes at least one detection unit detecting a first physical variable of the control device. The device further includes an evaluation unit generating a first electrical signal on the basis of the first physical variable detected. The device also includes a first interface connecting the device to the communication unit. The first electrical signal is transmitted to the communication unit via the first interface. The detection unit detects at least one of an electrical resistance, an electrical voltage, a visual state an acoustic signal of the control device as the first physical variable.
VISUAL INSPECTION DIAGNOSTICS
A passenger conveyor diagnostic system includes a processor that stores at least one visual inspection diagnostic, and a passenger conveyor system including at least one sensor configured to capture one or both of an image and a sound. The processor applies the at least one visual inspection diagnostic to one or both of the image and the sound to generate a diagnosed status of the passenger conveyor system, and overlays the diagnosed status of the passenger conveyor system on the image.
Rescue/Evacuation Self-Testing System for Traction Elevators
A monitoring system for controlling self-testing of a traction elevator includes a self-testing process module in communication with a three-phase AC back-up battery power supply. The self-testing process module includes a processor configured to initiate and control a series of steps for performing measurements of the three-phase AC back-up battery power supply, including measurements of the battery supply during a simulated emergency situation (“rescue/evacuation”). The processor is programmed to initiate testing on a defined schedule and transmit test results to a maintenance system (including remotely-located systems) on a routine basis. The monitoring system also includes a display unit providing visual information regarding the status of self-testing processes and their results and a communications unit for transmitting test results to a remote maintenance controller.
METHOD AND SYSTEM FOR CONFIGURING AN ELEVATOR MANAGEMENT DEVICE
An illustrative example embodiment of a method of configuring an elevator management device includes issuing a predetermined series of commands to perform a corresponding series of elevator system functions; for each of the series of elevator system functions, automatically determining a respective portion of an elevator controller that is active during a corresponding one of the activated series of elevator system functions; automatically generating information including a relationship between the respective portions of the elevator controller and the corresponding ones of the activated series of elevator system functions; and configuring the elevator management device to communicate with the elevator controller based on the information.
