Abstract: A floor position detection device of an elevator installation, and a method for generating a floor signal, includes a sensor unit and an evaluation unit for generating the floor signal with two states. The states are “in the range of the floor” and “outside the range of the floor”. The sensor unit includes a first Hall effect sensor generating a first floor position characteristic value and a second Hall effect sensor generating a second floor position characteristic value. The evaluation unit generates the floor signal on the basis of a comparison between the first and the second floor position characteristic values. The evaluation unit verifies whether the first and/or second floor position characteristic value is higher than a first threshold value and generates the floor signal on the basis of the result of the verification.

Abstract: A safety monitoring device monitoring safety-related states in a passenger conveyor system has first and second double contact relays each controlled by a control voltage to switch first and second normally open contacts and a feedback contact synchronously between an open and closed relay states. First and second controllers each determine properties of the system correlated with safety-related states and in dependence generate the control voltages. The controllers and two double contact relays form first and second safety monitoring switch arrangements for monitoring first and second safety-related states and correspondingly switch first and second switching states within a safety monitoring chain of the system. The first arrangement includes the first contact of the first connected in series with the first contact of the second relay. The second arrangement includes the second contact of the first relay connected in parallel with the second contact of the second relay.

Abstract: A system and method for determining an elevator car position uses position markers situated in the elevator shaft and each assigned a discrete car position, first and second detection devices on the elevator car detecting first and second position markers respectively, and an evaluation unit that determines first and second discrete car positions based on the detected first and second position markers respectively. A single interpolation device of the position determining system determines first and second interpolated car positions. The evaluation unit determines first and second car positions based on the first and second discrete car positions and the first and second interpolated car positions respectively. The interpolation device generates an interpolation parameter that characterizes a position of the first detection device relative to the first position marker and determines the first and second interpolated car positions on the basis of the interpolation parameter.

Abstract: A method for configuring security related configuration parameters is used in a passenger transport installation that includes at least one sensor exchanging sensor signals with a control. The sensor detects operating parameters within the passenger transport installation and emits corresponding sensor signals. The control controls security related functions of the passenger transport installation taking into account the sensor signals and the configuration parameters. The method includes: comparing the sensor signals with a predefined key signal pattern; operating the control temporarily in a configuration mode exclusively if the compared sensor signals correspond to the key signal pattern; and configuring the security related configuration parameters during the configuration mode. An installation-specific sensor (e.g. optical sensor or magnetic field sensor) functions as an interface to put the control into configuration mode in a targeted manner, e.g.

A position detecting unit continuously detects the position of the car relative to the track and communicates the position to the control device that continuously detects whether the car is located in the region of a stopping point zone by comparing the communicated car position to stored position limit values of the stopping point zones.

Abstract: A position-determining system and a method for ascertaining a car position of an elevator car use a code tape mounted next to the elevator car in parallel with a movement direction and that includes a code-mark pattern of individual code marks, a detection apparatus mounted on the elevator car that detects the code marks, and an evaluation unit that determines the car position on the basis of the detected code marks. Here, n successive code marks of the code-mark pattern form a position mark, the position marks are unambiguously arranged in an n-digit pseudorandom sequence of various position marks, the position marks form a single-track code-mark pattern, and a discrete car position is assigned to each position mark. A detection region of the detection apparatus has a detection length in the movement direction that is shorter than a position-mark length of a position mark in the movement direction.
