Embodiment Construction

[0087] figure 1 An elevator installation 3 according to the invention is shown with a drive unit 38 by means of which an elevator car 36 arranged in an elevator shaft 35 can be moved between two elevator doors 30A, 30B. The elevator installation 3 supplied by the central power supply unit 2 is equipped with a control device 100 via which the elevator installation 3 , in particular the drive unit 38 , can be controlled. For monitoring the elevator installation 3 , the control device 100 includes a safety unit 1 which is connected or connectable to a monitoring unit 10A, 10B via which the lock 31A, 31B of the associated elevator door 30A, 30B can be monitored respectively.

[0088] The insurance unit 1 is in this configuration an independent computer system which communicates with the system computer 1000 . However, the safety unit 1 can also be integrated into the system computer 1000 as a software module or a hardware module. Such as figure 1 As shown in , safety unit 1 can...

Abstract

The method and the apparatus are used for securely controlling an elevator system (3) comprising a drive unit (38) which allows an elevator car (36) located in an elevator shaft (35) to move and whichis controlled in a secured manner by a control device (100) in such a way that during normal operation, the elevator car (36) can move to at least two access points to the elevator shaft (35) at which doors (30A, 30B) are provided. The elevator car (36) does not move or moves only to a limited extent if an individual is in the elevator shaft (35). A monitoring unit (10A; 10B) and a monitoring sensor (11A; 11B) that allow changes in state to be detected are associated with at least one of the doors (30A, 30B). The monitoring unit (10A; 10B) is equipped with a battery (14) and can be switched to an autonomous mode when the elevator system (3) is entirely or partially out of order. The monitoring unit (10A; 10B) is connected to the monitoring sensor (11A; 11B) and, in the autonomous mode, monitors the state of the monitoring sensor (11A; 11B) and records state data; furthermore, the monitoring unit (10A; 10B) is connected to a securing unit (1) which reads the recorded state data from all connected monitoring units (10A; 10B), evaluates said state data and prevents the elevator system (3) from being put into the normal mode of operation if a change in the state of one of the monitored doors (30A; 30B) has been detected. The monitoring sensor (11A, 11B) is a switching contact which is coupled to the associated door lock (31A; 31B) and via which a monitoring signal is transmitted from an output to an input of the monitoring unit (10A; 10B). According to the invention, the monitoring signal is in the form of a sequence of pulses.

Description

technical field [0001] The invention relates to a method and a device for securely controlling an elevator installation. Background technique [0002] An elevator installation generally comprises an elevator car, an elevator shaft in which the elevator car moves, and a drive unit for moving the elevator car. [0003] From WO 2005 / 000727 A1 it is known that an elevator installation has a safety circuit in which a plurality of safety elements, such as safety contacts and safety switches, are arranged in the safety circuit. The contacts monitor, for example, whether shaft or car doors are open. The elevator car can only be moved when the safety circuit is closed and thus also all safety contacts integrated therein are closed. Some of the security elements are operated by the door. Other safety elements, such as overrun switches ( ), manipulated or triggered by the elevator car. The safety circuit is connected to the drive or braking unit of the elevator system, so that th...
