Problems solved by technology

[0004] The disadvantage of this solution is that the additional security itself is not monitored
Therefore, when the additional safety parts fail, it is impossible to monitor the operation of the inverter and / or controller, which will lead to an uncontrolled braking process

Embodiment Construction

[0018] figure 1 It is a circuit block diagram of the braking system of the personnel conveying equipment, and the description of the personnel conveying equipment will not be repeated here. The drive motor of the people conveyor is operatively connected to an electromechanical holding brake 2, which is preferably a brake shoe brake. The frequency converter 3 is connected via a line 4 to two series-connected drive circuit breakers, which are represented by contacts 5 . When the drive circuit breaker 5 is controlled, the frequency converter 3 acts on the drive motor 1 . The controller 6 is effectively connected with the frequency converter 3 and the driving circuit breaker 5 on the one hand, and is effectively connected with the clamping brake 2 on the other hand. The safety system 7 includes, for example, safety circuits and / or safety devices for overspeeding and unintentional reversal of the direction of travel. The safety system 7 and the safety circuit are connected with ...

Abstract

The invention relates to a method for stopping conveying equipment for persons, wherein on response of a safety element a braking process determined by a frequency converter (3) co-operating with a drive motor (1) is initiated, by means of which the conveying equipment for persons is brought to a standstill, wherein the braking proces s is monitored by a safety circuit (8, 9) which comprises at least a first channel (8) and a second channel (9) The operational safety of the braking system is thereby increased.

Description

technical field [0001] The invention relates to a method for stopping the operation of personnel conveying equipment, wherein when the safety element acts, the braking process determined by the frequency converter coordinated with the drive motor is started, and the personnel conveying equipment is stopped through the braking process; the present invention It also relates to a safety circuit for monitoring a braking device for stopping the operation of a personnel conveying device, wherein when the safety part is activated, the braking process determined by the frequency converter cooperating with the drive motor is started, so The personnel conveying equipment is stopped through the braking process. Background technique [0002] The personnel conveying equipment mentioned in this application refers to escalators and moving walkways. [0003] In DE-19803899 C2 a method of braking an escalator or a moving walkway is disclosed, in which the frequency converter is controlled w...
