Abstract

A passenger transport system and a method of operating the same are described. The passenger transport system includes a passenger conveying device, a control unit for controlling an operation of the passenger conveying device, and a disinfecting device for disinfecting a surface to be disinfected on the passenger conveying device. The disinfecting device includes a controller for controlling an operation of the disinfecting device. The control unit of the passenger transport system and the controller of the disinfection device are adapted in such a manner that status signals, which reflect information about a current operation, a current state, and/or a current configuration of the disinfection device, are sent from the controller to the control unit, and the control unit generates control signals taking into account received status signals and transmits them to the controller, wherein the controller controls the operation of the disinfection device taking into account received control signals.

First claim

The invention claimed is:

1. A disinfection device for disinfecting a surface on a passenger conveying device, wherein the passenger conveying device is part of a passenger transport system and is used for conveying passengers within a building structure, the device comprising:
a controller for controlling an operation of the disinfection device, wherein the controller is configured to be connected to a control unit of the passenger transport system via a bidirectional communication system, and
at least one ultraviolet-C light emitting diode,
wherein the controller of the disinfection device is configured to send status signals, which reflect information about at least one of a current operation, a current state, or a current configuration of the disinfection device, to the control unit and to receive control signals generated by the control unit of the passenger transport system taking into account received status signals, wherein the controller controls the operation of the disinfection device taking into account received control signals,
wherein the controller of the disinfection device is configured to control a disinfection intensity of the at least one ultraviolet-C light emitting diode with which the disinfection device disinfects a surface to be disinfected, depending on control signals which are transmitted to the controller by the control unit of the passenger transport system and which indicate an operating parameter of the disinfection device correlating with a disinfection intensity of the at least one ultraviolet-C light emitting diode currently to be effected,
wherein the control unit of the passenger transport system or the controller of the disinfection device are adapted to increase the operating parameter of the disinfection device correlating with a currently effected disinfection intensity of the at least one ultraviolet-C light emitting diode depending on an operating time since start-up of the disinfection device.

2. A passenger transport system, comprising:
a passenger conveying device for conveying passengers within a building structure;
a control unit for controlling an operation of the passenger conveying device; and
a disinfection device for disinfecting a surface to be disinfected on the passenger conveying device;
wherein the disinfection device comprises a controller for controlling an operation of the disinfection device and at least one ultraviolet-C light emitting diode;
wherein the controller of the disinfection device is connected to the control unit of the passenger transport system via a bidirectional communication system, and
wherein the control unit of the passenger transport system and the controller of the disinfection device are adapted in such a manner that status signals, which reflect information about a current operation, a current state and/or a current configuration of the disinfection device, are sent from the controller to the control unit, and the control unit generates control signals taking into account received status signals and transmits them to the controller, wherein the controller controls the operation of the disinfection device taking into account received control signals,
wherein the controller of the disinfection device is adapted to control a disinfection intensity of the at least one ultraviolet-C light emitting diode with which the disinfection device disinfects the surface to be disinfected depending on control signals which are sent to the controller by the control unit of the passenger transport system and which indicate an operating parameter of the disinfection device correlating with a disinfection intensity of the at least one ultraviolet-C light emitting diode currently to be effected,
wherein the control unit of the passenger transport system or the controller of the disinfection device are adapted to increase the operating parameter of the disinfection device correlating with a currently effected disinfection intensity of the at least one ultraviolet-C light emitting diode depending on an operating time since start-up of the disinfection device.

3. The system of claim 2 , wherein the control unit generates control signals which indicate a setpoint value for the operating parameter of the disinfection device correlating with a disinfection intensity of the at least one ultraviolet-C light emitting diode currently to be effected, taking into account the status signals received from the controller.

4. The system of claim 2 , wherein:
the disinfection device is configured to be able, in a new state, to effect as a maximum disinfection intensity of the at least one ultraviolet-C light emitting diode a disinfection intensity of the at least one ultraviolet-C light emitting diode which is greater than a minimum disinfection intensity necessary for sufficient disinfection of the surface to be disinfected, and
the control unit of the passenger transport system or the controller of the disinfection device are adapted to operate the disinfection device in normal operation with a disinfection intensity of the at least one ultraviolet-C light emitting diode above the minimum disinfection intensity and to successively increase an operating parameter of the disinfection device correlating with a currently effected disinfection intensity of the at least one ultraviolet-C light emitting diode.

5. The system of claim 2 , wherein:
the disinfection device further comprises a sensor for detecting a measured variable which correlates with the disinfection intensity of the at least one ultraviolet-C light emitting diode, and
the control unit of the passenger transport system and/or the controller of the disinfection device are adapted to increase the operating parameter of the disinfection device correlating with a currently effected disinfection intensity of the at least one ultraviolet-C light emitting diode depending on the measured variable detected by the sensor.

6. The system of claim 5 , wherein the control unit of the passenger transport system or the controller of the disinfection device are adapted to regulate the operating parameter of the disinfection device correlating with a currently effected disinfection intensity of the at least one ultraviolet-C light emitting diode depending on the measured variable detected by a sensor.

7. The system of claim 2 , wherein the operating parameter of the disinfection device correlating with a disinfection intensity of the at least one ultraviolet-C light emitting diode currently to be effected is monitored and, if the operating parameter exceeds a predetermined threshold value, a warning signal is output which indicates an approaching end of a service life of the disinfection device.

8. The system of claim 2 , wherein:
the disinfection device further comprises a sensor for detecting a temperature inside the disinfection device or for detecting a temperature in an environment adjacent to the disinfection device, and
the control unit of the passenger transport system or the controller of the disinfection device are adapted to control the operation of the disinfection device depending on the temperature detected by the sensor.

9. The system of claim 5 , wherein the controller of the disinfection device is adapted to send the measured variable determined by the sensor or a data signal correlating with the measured variable determined by the sensor to the control unit of the passenger transport system.

10. The system of claim 2 , wherein the passenger transport system further comprises an interface device adapted to send data from the control unit of the passenger transport system to a remotely arranged computer and/or to provide data from a remotely arranged computer for reception by the control unit of the p
