Problems solved by technology

Sudden shutdown of an elevator system is undesirable for several reasons: firstly, it is unpleasant for the operator of the elevator system, and maintenance personnel must be called in if the elevator shuts down suddenly
Secondly, high manpower and logistics input are required to ensure that the elevator system that needs maintenance can be repaired at any time

Embodiment Construction

[0022] FIG. 1 shows a part of a transport system 2 , ie the main components of an elevator system, in particular an elevator car 4 , an elevator shaft door opening 6 and an elevator shaft door comprising two door panels 8 and 10 . When the door panels 8 and 10 are open, the car 4 is in a slightly downward position with the hoistway door opening 6 . The detection safety switch TCI12 is connected with the elevator controller (not shown) through a connecting piece (not shown) arranged on the top of the elevator car 4, and TCI is the top of car inspection (Top of Car Inspection).

[0023] Both the first member 14 and the second member 16 of the safety switch 18 are connected to the elevator controller and are arranged on the end faces of the door panels 8 and 10 . Such a suitable safety switch has been developed by Bernstein AG of Germany.

[0024] The elevator car 4 can also include an elevator car door with a safety switch 18 .

[0025]The door panels 8 and 10 are detachably m...

Abstract

A transport system (2) comprising a controller, a drive motor and a safety switch (18) connected to a safety-related component (8, 10) of the transport system (2) capable of distinguishing the transport system (2) Whether it is in a safe state, and connected with the controller so as to cut off the power supply of the drive motor in a non-safe state, and especially in addition to detecting a safe state and an unsafe state, it can also detect a warning state.

Description

technical field [0001] The present invention relates to a transportation system, especially a passenger transportation system such as an elevator, a moving sidewalk or an escalator, the transportation system is provided with a controller, a driving motor and a safety switch capable of distinguishing whether the transportation system is in a safe state, the The safety switch is connected with the controller so as to cut off the power supply of the driving motor in an unsafe state. Background technique [0002] This type of transportation system is widely used in elevators, as well as in escalators or moving walkways. The aforementioned safety switch enables monitoring of the relevant safety state of the transport system. For example in an elevator system the elevator car doors are continuously monitored if there are elevator shaft doors. When one of the doors is opened, the controller will cut off the power to the drive motor, and the power to the drive motor will not be re...
