Definitions

  • the invention relates to a monitoring system for monitoring a shaft or cabin door of an elevator system.
  • elevator systems have so-called double doors, i.e. shaft doors as well as car doors arranged on the elevator car.
  • the opening or closing of the shaft doors is usually initiated by the cabin or the cabin doors.
  • all shaft doors must always be closed during operation, with the exception of the shaft door of the floor on which the elevator car is currently stopping.
  • the car doors must be closed when the elevator is not currently stopping on one floor in order to be loaded or unloaded or to be entered or left.
  • the shaft and / or car doors can of course also be opened if the elevator car is located elsewhere than in the positions described above.
  • the state ie the position of the shaft and cabin doors or the position of bolts with which the shaft and or cabin doors can be locked in their closed positions, are monitored with the aid of monitoring systems.
  • sensor means are provided, for example in the form of positively driven devices with safety contact points.
  • the safety contact points are integrated in series in a safety circuit. The arrangement is such that the elevator car can only be moved if the safety circuit and thus all safety contacts integrated in it are closed.
  • Monitoring systems with security circuits of this type have numerous disadvantages, which are briefly listed below.
  • Each safety circuit has inherent problems; this includes the length of the connections, the voltage drop in the safety circuit and the relatively high installation effort.
  • the individual safety contacts are relatively susceptible to faults; therefore, there is often an unnecessary emergency stop of the elevator system.
  • the monitoring system does not allow specific diagnosis; this means that with an open safety circuit it is only determined that at least one safety contact and thus at least one bolt or at least one
  • the availability of the elevator is restricted because an open safety contact always results in the elevator system being taken out of service, even if another solution, for example blocking off the access area to a shaft door that cannot be closed, would be possible.
  • the object of the invention is therefore seen to provide an improved monitoring system of the type mentioned at the outset, with which the disadvantages of the prior art can be avoided or at least greatly reduced.
  • the detection of the state of the shaft or cabin doors by the sensor means should be able to be analyzed and diagnosed.
  • gradual deterioration of individual subsystems should be identified so that preventive maintenance can be initiated in good time.
  • the new monitoring system should preferably act in such a way that malfunctions or failures of individual contacts do not lead to failure of the entire elevator system.
  • the shaft doors and / or the car doors have sensor means with which their state, that is to say the taking of their open or closed position, is detected.
  • the monitoring system also has an evaluation system which is connected to the sensor means and which evaluates the signals supplied by the sensor means. This evaluation is carried out in short time intervals and allows the status of the monitored shaft or cabin door to be recorded; Changes in the signal characteristics over time can also be recorded.
  • the evaluation unit can also locate an error from the signals from the sensor means, and thus an analysis and diagnosis relating to the error is possible.
  • the signal characteristics of the Signals delivered to sensor means can also be detected in terms of quality degradation over time, so that precautionary maintenance measures can be initiated.
  • the evaluation system is preferably designed in such a way that it can in particular detect and localize an error and / or determine a defect in a sensor device and / or determine whether sensor devices are worn out and / or can detect incorrect manipulations on the shaft door associated with a specific sensor device and / or recognize the need for maintenance and / or recommend maintenance.
  • an evaluation system can be provided for each floor; this evaluation system is preferably connected to an elevator control system via a data bus.
  • a common evaluation system can be provided for several floors; Such an evaluation system is also preferably connected to an elevator control system via a data bus.
  • the evaluation system has a local processor in order to evaluate the signals from the sensor means.
  • a particularly favorable arrangement is obtained if the evaluation system of the new monitoring system can also process other signals or data from the elevator system, that is to say other elevator sizes.
  • redundancy in the elevator system can be used, for example, for example, on the one hand, a sensor means indicates the closed position of a car door and, on the other hand, an incremental encoder of the door drive also detects the closed position of the car door.
  • the evaluation system is designed in such a way that it also records the changes over time in the signal characteristic, that is to say the characteristic of the signals to be evaluated; this makes it possible to detect abnormal bouncing behavior of sensor means or abnormal dynamic signal profiles and / or abnormal static conditions, for example a voltage drop, on sensor means. This makes it possible to carry out diagnostics at the level of individual components and to initiate preventive maintenance of individual sensors.
  • a sensor means that comprises at least two redundant sensors; this can prevent the failure of a single sensor from leading to failure of the entire elevator system equipped with the new monitoring system;
  • the elevator system can remain in operation at least for a short time if a sensor of a sensor means is no longer functional.
  • a sensor means has proven to be particularly favorable which comprises two sensors which are arranged in the area of a shaft door or the cabin door in such a way that during the closing or opening or during the change of the
  • first one of the two sensors and later the second one of the two sensors delivers a signal.
  • a first sensor emits a signal when a shaft or cabin door is closed except for a remaining door gap, approximately 10 mm
  • the second sensor emits a signal when the shaft or cabin door is complete is closed and locked. In this way it can be seen whether a shaft or cabin door closes completely or no longer closes completely due to contamination, mechanical wear and tear, deformation. In this way you get a diagnosis at the level of
  • the monitoring system can be designed so that there is no interruption in operation if the remaining door gap does not exceed a limit value, but a service call is generated at the same time.
  • the evaluation system advantageously triggers at least one predefined reaction, in particular the localization of an error and / or the generation of a service call and / or the storage of diagnostic information and / or the stopping of the elevator car or the execution of one other situation-dependent reaction if a shaft door was identified as open.
  • Figure 1 shows a shaft or car door of an elevator system with a first monitoring system according to the invention, in a highly simplified schematic representation.
  • FIG. 2 two shaft or car doors of an elevator system with a second monitoring system according to the invention, in the same representation as FIG. 1.
  • An elevator system (not shown further) has a door 10, which can be a shaft door or a cabin door.
  • This door 10 is assigned sensor means, namely a first sensor means 12 and a second sensor means 14.

  • bus node 22 In addition to the signals supplied by the sensor means 12, 14, other signals, that is to say different lift sizes, are connected to the bus node 22 via further connections 30, 32; also a connection to the evaluation system or not shown integrated computer would be possible.
