Definitions

  • the present invention relates to a control device for controlling the operation of a passenger transport system such as an elevator system, an escalator or a moving walkway.
  • sensors can be provided in the passenger transport system to monitor such functions, and conclusions can be drawn from sensor signals of such sensors about correct or incorrect functioning of a component or a component and thus about an intended or incorrect implementation of the monitored function to be implemented by the component .
  • door switches can be used as a type of sensor, in which a sensor signal changes depending on whether an elevator door to be monitored is open or closed and locked. Only when all door switches signal that all elevator doors are closed and locked can a control device of the elevator system cause the elevator car to be moved within the elevator shaft to another floor.
  • a control device for controlling an operation of a passenger transport system.
  • the passenger transport system here has several sensors.
  • Each of the sensors is configured to monitor a function of at least one component in the passenger transport system and to transmit a sensor signal representing a current status of the function to the control device.
  • the control device is configured to control the operation of the passenger transport system as a function of the sensor signals from the multiple sensors.
  • the sensors are configured to gradually generate different situation-specific sensor signals depending on a currently prevailing state of the respectively monitored function.
  • Signal communication between the sensors and the control device is configured to send the sensor signals for each of the sensors individualized with information about an identity of the sensor To transmit control device.
  • the control device is configured to control the operation of the passenger transportation system as a function of at least one decision parameter in a situation-dependent limited operating mode in which the passenger transportation system continues to be operated with reduced functionality.
  • the decision parameters include the situation-specific sensor signals transmitted by the plurality of sensors and / or the information about the identity of the sensor transmitting the respective sensor signal.
  • a passenger transport system which has a drive machine, a plurality of sensors and a control device.
  • Each of the sensors is configured to monitor a function of at least one component in the passenger transport system and to transmit a sensor signal representing a current status of the function to the control device.
  • the sensors are configured to generate various situation-specific sensor signals depending on a currently prevailing state of the function being monitored.
  • Signal communication between the sensors and the control device is configured to transmit the sensor signals for each of the sensors individually with information about an identity of the sensor to the control device.
  • the control device is designed according to an embodiment of the first aspect of the invention and is configured to control the operation of the drive machine as a function of the sensor signals of the plurality of sensors.
  • the passenger transport system can, depending on the situation, continue to be operated in a limited operating mode in which at least one or some of its functionalities are restricted.
  • the passenger transport system should have a plurality of sensors for this purpose.
  • Each of these sensors should be configured to monitor a function of a component of the passenger transport system or a property of the component influenced by this function.
  • a sensor can measure a physical parameter that represents a measure of the function to be fulfilled by the component.
  • the sensor should then output a sensor signal that provides information about the current status of the monitored function. This sensor signal should be transmitted to the control device of the passenger transport system.
  • the sensors should be specially configured to not only be able to recognize whether a component implements its function completely as required or not at all. Instead, a sensor should be able to gradually recognize a currently prevailing state of the respectively monitored function and accordingly to be able to gradually generate different situation-specific sensor signals. In other words, a sensor should also be able to detect when a component to be monitored is no longer performing its function correctly, but is still implementing the function to a temporarily acceptable level and is therefore not considered a defect in the sense that its defective function can be continued excludes the passenger transport system.
  • signal communication between the multiple sensors and the control device should be configured such that the sensors can transmit their sensor signals to the control device and this can be done individually in such a way that the control device receives information about an identity of the sensor transmitting a control signal.
  • the control device should be able to recognize from which of the plurality of sensors a specific control signal originates.
  • the control device can then control the operation of the passenger transport system as a function of the situation-specific sensor signals which it receives from the multiple sensors and / or as a function of the information about the identity of the sensor transmitting a respective sensor signal.
  • control device receives, for example, a sensor signal which signals a restricted functionality in a monitored component, it can control the operation of the passenger transport system in a limited operating mode as a function of the situation.
  • a limited operating mode for example, a behavior or a functionality of the passenger transport system can be modified in such a way that the observed restricted functionality of the monitored component is taken into account.
  • control device can, for example, when it receives a sensor signal from a specific sensor identified by the information about the identity, control the operation of the passenger transport system in a limited operating mode as a function of the situation. Since it is known which sensor the sensor signal originates from and therefore which function to be monitored in the passenger transport system is reproduced by the sensor signal, the limited operating mode can be selected in such a way that any malfunctions occurring in the monitored function are taken into account.
  • a drive of the passenger transport system can be operated temporarily at a maximum reduced power that is less than a maximum power in a normal operating mode.
  • the drive of the passenger transport system can be monitored with the aid of one or more sensors for an operating temperature or a converted electrical power. If sensor signals indicate that the operating temperature or the converted electrical power increases beyond what is considered normal, this can be interpreted as an indication of a malfunction in the passenger transport system.
  • the passenger transport system can be designed as an elevator system and the control device can be configured to control the operation of the elevator system in a situation-dependent limited operating mode in which an elevator cage is no longer stopped on a floor where experience has shown or determined by a Sensor system plans a number of passengers exceeding a maximum value to get into the elevator car.
  • the functionality in the limited operating mode can be reduced to the effect that certain floors are no longer approached by the elevator car.
  • the elevator system can have a sensor system, for example in the form of a camera, which, for example, can determine a number of passengers waiting for the elevator car on a floor, so that the elevator car is not stopped on the floor in question if there are a particularly large number of waiting passengers. In this way, the possibly reduced conveying capacity of the elevator system during the limited operating mode can be taken into account.
  • the floor in question can, for example, preferably be served by one of the other elevator systems.
  • the passenger transport system can again be designed as an elevator system and the control device can be configured to control the operation of the elevator system in a situation-dependent limited operating mode in which an elevator car is no longer stopped on a floor where at least one of the sensors is at least temporarily is positioned, from which a situation-specific sensor signal was transmitted to the control device, which indicates a malfunction of a component of the elevator system arranged on the floor in question.
  • a component which is arranged on a certain of the floors served by the elevator system has a malfunction which can impair the operation or even the safety of the elevator system.
  • the malfunction does not necessarily have to justify a complete cessation of operation of the elevator system.
  • Such a malfunction can be detected by one of the sensors communicating with the control device.
  • the sensor can be arranged stationary on the floor on which the component is located.
  • the sensor can, for example, be moved together with the elevator car between different floors and, when it reaches the floor with the component concerned, detect the malfunction.
  • this information can be combined, for example, with information about the identity of the sensor as well if necessary, in the event that the sensor should be mobile, information about the current location of the sensor can be forwarded to the control device.
  • the control device can thus be informed about the malfunction occurring on a floor.
  • the control can then cause the elevator car on the floor in question to at least no longer be stopped. Alternatively, the control can cause the elevator car not to be moved to the affected floor at all.
  • control device can also be configured to communicate a warning signal to an external monitoring device as a function of at least one of the decision parameters.
  • control device can not only control the operation of the passenger transport system itself, depending on the situation, in the limited operating mode if one of the above-mentioned decision parameters indicates a malfunction in a component of the passenger transport system, but can also transmit a warning signal to an external monitoring device.
  • the external monitoring device can, for example, be a remote control center from which the operation of several passenger transport systems is monitored. On the basis of the warning signal received, the monitoring device can, for example, initiate an inspection, repair or maintenance of the passenger transport system.
  • the warning signal is preferably not only transmitted to the monitoring device when a malfunction is present that requires the operation of the passenger transport system to be stopped immediately, but rather when only a malfunction has been detected that causes a transition to a limited operating mode, but still no immediate cessation of operation of the passenger transport system is mandatory.
