Elevator safety system
TL;DR: In this paper, an elevator safety system including a plurality of communication controllers configured to communicate, over a network, signals including a safety control signal is presented, and a control device connected to a first communication controller is configured to execute operation control of the elevator.
Patent
Elevator monitoring method, device, terminal and facility and monitoring platform and system
TL;DR: In this article, an elevator monitoring method is applied to an acquisition terminal and comprises the steps that according to the elevator running characteristic, state data of an elevator are collected; the elevator state is determined according to state data, according to which a collection data packet is generated; the packet is sent to network equipment, and accordingly, the network equipment is triggered to send an effective data packet to the monitoring platform, wherein the effectivedata packet carries the key state data.

Elevator safety system and method of operating an elevator system
Peter Herkel,Dirk H. Tegtmeier +1 more
TL;DR: In this article, the authors describe an elevator system consisting of a hoistway (4) extending between a plurality of landings (8, 9), at least one hoistsway door (10, 11) allowing access to the hoistways (4); an elevator car (6), which is configured to move along the hoistswreeway (4), an electronic safety actuator (18) which is attached to the elevator car and configured to stop any movement of the car when activated; and a door safety switch (20) which was configured to monitor the
Patent
A communication system for transmitting safety information in an elevator system
TL;DR: In this paper, the authors provided a communication system for transmitting safety information in an elevator system, where the first node (102) is configured to receive first safety information from a first safety node (110) via two parallel communication channels.

Transmitter circuit, receiver circuit, clock data recovery phase locked loop circuit, data transfer method and data transfer system
TL;DR: In this paper, the authors proposed a digital data transfer method for alternating and periodically transferring first information and second information respectively in a first period and in a second period, wherein the first information in the first period is transferred as pulsewidth-modulated serial data and the second information is transferred in the second period as serial data.
Patent
Electronic safety system for elevators having a dual redundant safety bus
TL;DR: In this article, an electronic safety system for elevators for preventing unsafe elevator operation has been proposed, where a central controller monitors a variety of sensors, contacts, and switches over a safety bus.
Patent
Device and method for remote maintenance of an elevator
Karl Weinberger,Kilian Schuster +1 more
TL;DR: In this paper, the authors present a set of remote maintenance functions stored in the data memory and each of these remote maintenance function is selectively activatable for remote maintenance and monitoring of an elevator.
Patent
Procedure for supplying, storing and displaying elevator control data
TL;DR: In this paper, a procedure supplies and modifies the data required in the control system of an elevator and for displaying the instructions needed for installation, maintenance and adjustment on a display comprised of a control system.
Patent
Method for transmitting messages in an elevator communications system
TL;DR: In this paper, a two-way ring elevator communications system is characterized in which a controller is associated with each elevator to process inter-elevator messages and the controllers of the elevators are linked together in serial fashion on a twoway communications system so that the messages of each controller are passed along to and processed by each of the other controllers in two directions on two independent rings.
