Monitoring equipment for an elevator drive control includes two modules, a safety circuit sensor system and a motor-switching and/or brake-switching circuit, wherein the monitoring of a safety circuit and the consequential actions resulting therefrom takes place exclusively by means of electronic components while avoiding electrically conductive separating locations. By the use of electronic components, electromechanical switching elements, which have electrically conductive separating locations, can be dispensed with. In addition, an appreciable reduction in the noise level is achieved, since switching noises no longer arise. This has an advantageous effect particularly in the case of elevator installations without a machine room. Furthermore, the manufacturing costs can be significantly reduced and a high security and reliability of the monitoring equipment can be ensured by the use of usual electronic components.

A device for remote maintenance and monitoring of an elevator installation has at least one input for the detection of first signals from an elevator control and/or from a sensor, at least one output of second signals to a telecommunications network and a processor and a data memory. A set of remote maintenance functions is stored in the data memory and each of these remote maintenance functions is selectively activatable.

An elevator system which an autonomous mobile robot and human user can utilize safely and efficiently. The system has an available area detection unit to detect an available area in a cage, and a riding possibility/impossibility determination unit to determine whether or not the autonomous mobile robot can get on the cage based on information on size and position of the available area detected by the available area detection unit. The autonomous mobile robot gets on the cage only when the riding possibility/impossibility determination unit determines that riding is possible.

A device for monitoring an elevator area utilizes a three-dimensional semiconductor sensor for detecting three-dimensional image information. The sensor includes a light source that is mounted so that the elevator area to be monitored is disposed in the illuminated area of the light source, a sensor group that is mounted in such a manner that it receives reflected light, and a processing chip for converting the electrical signals into image information. In addition, the device includes a processing device that is connected with the semiconductor sensor in order to make available three-dimensional image information. The processing device processes the image information in order to obtain state information representing the state of the elevator area to be monitored.

An intelligent elevator control system comprises an elevator controller, a central processing platform and a remote server. The central processing platform is installed in an elevator cage and connected with the elevator controller and the remote server. The central processing platform is used for providing an operation interface for an elevator riding user or directly recognizing the elevator riding authority of the elevator riding user. The central processing platform judges whether the user has the elevator riding authority according to the operation of the user or the automatic recognition result and through the combination of the identity information, stored in the remote server, of the elevator riding user and controls the elevator controller correspondingly. The elevator controller controls the elevator cage to run. The elevator riding authority of the user is managed, and the user can conveniently ride an elevator through wireless identity recognition measures; for the cloud service network information of the user, precise video advertisements can be automatically pushed to the user and property community public information can be automatically broadcasted to the user; the requirements for vision and information are met when the user rides the elevator.

Brake equipment for holding and braking an elevator car in an elevator installation, which is arranged to be movable along a brake track in two directions of travel, includes a mount with a brake lining which automatically adjusts under friction couple with the brake track on movement of the elevator car relative to the rail and in that case tightens a first tightening means, which can be released by an actuator. The first tightening means tightens the mount together with the brake lining against the brake track by a biasing force. The brake equipment produces, with unmoved brake equipment and an unreleased state of the actuator, a holding force acting in both directions of travel. The holding force is determined substantially by the biasing force acting on the mount.
