Embodiment Construction

[0041] figure 1 A people transport system 10 for a building is shown in the form of an elevator system 10 . The elevator equipment is introduced below by way of example. However, it should be appreciated that other people moving devices 10, such as escalators or moving walkways, may also have safety systems, as described below.

[0042] The elevator installation 10 comprises an elevator shaft 12 in which an elevator car 14 and a counterweight 16 are movable. For this purpose, the elevator car 14 and the counterweight 16 are held on a cable or belt-like carrier 18 which can be driven by a drive machine 20 . The operation of the lift installation 10 and in particular of the drive machine 20 can be controlled by means of a central control unit 22 .

[0043] In order to be able to ensure correct functioning and in particular safety of the elevator installation 10 , a plurality of safety sensors 26 are accommodated in the building 24 which accommodates the elevator installation ...

Abstract

A safety system (36) for a people mover (10) of a building includes a safety unit (40) for receiving safety-critical signals from components (26) of the people mover (10) and for triggering security measures; and an updating unit (38) for receiving updated software (50) via an external interface (42) and for sending updated software (50) to the security unit (40) via an internal interface (52).

Description

technical field [0001] The invention relates to a security system for a people conveyor of a building and a method for updating the software of the security system. Background technique [0002] People moving equipment in buildings, such as elevators, escalators, and moving walkways, are used to move people within buildings. Elevator installations are used, for example, to transport people between different floors within a building. For this purpose, the elevator car is generally movable within a mostly vertical elevator shaft. In the case of escalators or moving walkways, persons can be transported on an inclined or horizontal travel path standing on the foot units. [0003] In order to be able to ensure the safety of people, many building people movers have a safety unit which receives signals from safety-critical sensors, evaluates them and triggers safety measures if an unsafe state is detected. This safety measure can, for example, include stopping the people conveyo...
