Abstract

A method for configuring security related configuration parameters is used in a passenger transport installation that includes at least one sensor exchanging sensor signals with a control. The sensor detects operating parameters within the passenger transport installation and emits corresponding sensor signals. The control controls security related functions of the passenger transport installation taking into account the sensor signals and the configuration parameters. The method includes: comparing the sensor signals with a predefined key signal pattern; operating the control temporarily in a configuration mode exclusively if the compared sensor signals correspond to the key signal pattern; and configuring the security related configuration parameters during the configuration mode. An installation-specific sensor (e.g. optical sensor or magnetic field sensor) functions as an interface to put the control into configuration mode in a targeted manner, e.g. by a test piece with a barcode maintained in the field of view of the optical sensor.

First claim

The invention claimed is:

1. A method of configuring security related configuration parameters in a passenger transport installation, wherein the passenger transport installation includes a control and at least one sensor connected to the control for exchanging sensor signals, wherein the at least one sensor detects operating parameters within the passenger transport installation and emits corresponding ones of the sensor signals, wherein the control controls security related functions of the passenger transport installation taking into account the sensor signals emitted by the at least one sensor and taking into account the configuration parameters, the method comprising the steps of:
comparing the sensor signals emitted by the at least one sensor with a predefined key signal pattern;
operating the control temporarily in a configuration mode exclusively if the compared sensor signals correspond to the key signal pattern, wherein the sensor signals corresponding to the key signal pattern differ from all of the sensor signals emitted by the at least one sensor during a normal operation of the passenger transport installation; and
configuring the security related configuration parameters during the configuration mode.

2. The method according to claim 1 including configuring the security related configuration parameters based on the sensor signals emitted by the at least sensor during the configuration mode.

3. The method according to claim 1 wherein the at least one sensor is a magnetic field sensor, and wherein the magnetic field sensor is prompted to emit a signal pattern corresponding to the key signal pattern by a suitably statically premagnetized test piece being brought close to the magnetic field sensor.

4. The method according to claim 3 wherein, during the configuration mode, the magnetic field sensor is prompted to emit signals indicating desired configuration parameters by a suitably statically pre-magnetized test piece being brought close to the magnetic field sensor.

5. The method according to claim 3 wherein the magnetic field sensor is prompted, during the configuration mode, to emit signals indicating desired configuration parameters by dynamically generating a suitably predefined magnetic field close to the magnetic field sensor by a magnetic field generator.

6. The method according to claim 1 wherein the at least one sensor is a magnetic field sensor, and wherein the magnetic field sensor is prompted to emit a signal pattern corresponding to the key signal pattern by dynamically generating a suitably predefined magnetic field close to the magnetic field sensor by a magnetic field generator.

7. The method according to claim 6 wherein, during the configuration mode, the magnetic field sensor is prompted to emit signals indicating desired configuration parameters by a suitably statically pre-magnetized test piece being brought close to the magnetic field sensor.

8. The method according to claim 6 wherein the magnetic field sensor is prompted, during the configuration mode, to emit signals indicating desired configuration parameters by dynamically generating a suitably predefined magnetic field close to the magnetic field sensor by a magnetic field generator.

9. The method according to claim 1 wherein the at least one sensor is an optical sensor, and wherein the optical sensor is prompted to emit a signal pattern corresponding to the key signal pattern by a test piece with an optically readable static pattern being brought into a field of view of the optical sensor.

10. The method according to claim 9 wherein the optical sensor is prompted, during the configuration mode, to emit signals indicating desired configuration parameters by a test piece with an optically readable static pattern being brought into the field of view of the optical sensor.

11. The method according to claim 9 wherein during the configuration mode, the optical sensor is prompted to emit signals indicating desired configuration parameters by dynamically generating a predefined, optically readable pattern in the field of view of the optical sensor by a controllable light source.

12. The method according to claim 1 wherein the sensor is an optical sensor, and wherein the optical sensor is prompted to emit a signal pattern corresponding to the key signal pattern by dynamically generating a predefined, optically readable pattern in a field of view of the optical sensor by a controllable light source.

13. The method according to claim 12 wherein the optical sensor is prompted, during the configuration mode, to emit signals indicating desired configuration parameters by a test piece with an optically readable static pattern being brought into the field of view of the optical sensor.

14. The method according to claim 12 wherein during the configuration mode, the optical sensor is prompted to emit signals indicating desired configuration parameters by dynamically generating a predefined, optically readable pattern in the field of view of the optical sensor by a controllable light source.

15. The method according to claim 1 wherein the method is carried out exclusively within a predefined limited period of time following a system start of the passenger transport installation.

16. A passenger transport installation comprising:
a control and at least one sensor connected to the control for exchanging sensor signals;
wherein the control controls security related functions of the passenger transport installation taking into account configuration parameters;
wherein the at least one sensor detects operating parameters within the passenger transport installation and emits corresponding ones of the sensor signals; and
wherein the passenger transport installation configures the configuration parameters by performing the method according to claim 1 .
