Sensor Networks for People Transport Equipment

Abstract

A sensor network (3) for a personnel transport device (1) is presented. The sensor network (3) has: a master unit (35); a signal transmission device (17); and a plurality of sensor nodes (19). Each sensor node (19) has at least one sensor (21) for detecting a physical measured variable and is designed to transmit the detected measured variable to a master unit (35) via a signal transmission device (17). The main unit (35) has a sensor identification module (39), which is designed to determine at least one sensor (21) per sensor node (19), taking into account information previously stored in a database identification of the information comprising: (i) information of a first information type with information about reference measurements typically provided by the corresponding sensor (21) under foreseen conditions; (ii) information of a second information type , having information about the identity of the sensor node (19) containing the corresponding sensor (21), wherein the sensor node (19) has a plurality of different sensors (21) or a plurality of the same sensor (21) in different configurations ); and / or (iii) information of a third information type having information about a predetermined configuration of a sensor node ( 19 ) accommodating a corresponding sensor ( 21 ). The identification and especially the installation position of potentially structurally identical sensors ( 21 ) can be determined automatically in the sensor network ( 3 ), which can contribute to simplifying the installation of the sensor network ( 3 ) and avoiding errors.

Description

technical field [0001] The invention relates to a sensor network for people moving equipment, such as elevators, escalators or moving walks. The invention also relates to a people transport device equipped with such a sensor network. Furthermore, the invention relates to a method for determining the identity of a sensor in a sensor network for a people conveyor and a method for retrofitting an existing people conveyor. Background technique [0002] People moving equipment such as elevators, escalators or moving walkways are used to transport people and / or goods in a building or structure from one place to another. Here, the entire people moving facility is fixedly installed in the building, but has components such as elevator cars that can be moved between floors or revolving conveyor steps or such conveyor platforms by means of which, For example, passengers can be transported. [0003] In order to be able to recognize the operating state of the people mover, in particul...

AI Technical Summary

Problems solved by technology

[0011] In this case, however, the problem may arise that the elevator controller or evaluation device must always know from which sensors certain signals come from in order to be able to evaluate them rationally

However, this requires pre-providing unique IDs individually for each of the large number of sensors in the people mover

This may require considerable effort, for example in the production of sensors and / or in the provision of maintenance personnel for personnel transport systems
