Abstract

Methods, sensors, and machines for transmitting machine access data of a machine to a wireless measurement sensor attached to the machine. A method of transmitting access data of a communication interface of a machine to a wireless measurement sensor attached to the machine includes: controlling a machine component of the machine which influences the measurement signals of the measurement sensor, according to specific information associated with the access data and evaluating the measurement signals to determine the access data of the communication interface of the machine.

First claim

What is claimed is:

1. A method of transmitting access data of a communication interface of a machine to a wireless measurement sensor attached to the machine, the method comprising:
moving a movable machine component of the machine, which influences measurement signals of the wireless measurement sensor, relative to the wireless measurement sensor according to a motion pattern modulated with the access data; and
evaluating, by the wireless measurement sensor, the measurement signals to determine the access data of the communication interface of the machine.

2. The method of claim 1 , further comprising:
wirelessly connecting the wireless measurement sensor to the communication interface of the machine via the determined access data.

3. The method of claim 1 , wherein evaluating the measurement signals comprises:
evaluating the measurement signals to form a Morse code.

4. The method of claim 1 , wherein the motion pattern comprises a motion program modulated with the access data.

5. The method of claim 1 , wherein moving the machine component of the machine according to the motion pattern comprises:
moving the machine component in a direction towards each of multiple attachment positions.

6. The method of claim 1 , wherein
the motion pattern comprises one of a spatial motion pattern, a temporal motion pattern, and a spatial and temporal motion pattern.

7. The method of claim 1 , wherein a movement of the machine component comprises multiple motion segments.

8. The method of claim 7 , wherein the motion segments have at least one of: different velocities, different accelerations, or rest periods with different durations.

9. The method of claim 1 , wherein the wireless measurement sensor comprises one of a vibration sensor, a leveling sensor, a sound sensor, a light-sensitive sensor, a temperature sensor, a pressure sensor, a flow velocity sensor, or a camera.

10. The method of claim 1 , further comprising:
determining an actual attachment position of the wireless measurement sensor on the machine by the wireless measurement sensor.

11. The method of claim 10 , wherein determining an actual attachment position of the wireless measurement sensor comprises:
comparing the measurement signals of the wireless measurement sensor to reference measurement values or threshold values stored in the wireless measurement sensor.

12. The method of claim 1 , further comprising:
transmitting the measurement signals to the machine,
wherein an actual attachment position of the wireless measurement sensor on the machine is determined by the machine selecting from multiple attachment positions based on the measurement signals.

13. The method of claim 12 , wherein the machine comprises a memory for storing a respective reference measurement value for each of the multiple attachment positions, and
wherein the actual attachment position of the wireless measurement sensor on the machine is determined by the machine correlating the measurement signals of the wireless measurement sensor transmitted from the wireless measurement sensor with the respective reference measurement values for the multiple attachment positions stored in the memory.

14. A machine comprising:
a wireless measurement sensor;
a machine component movable to influence a measurement signal of the wireless measurement sensor;
a communication interface; and
a machine controller configured to move the machine component relative to the wireless measurement sensor according to a motion pattern modulated with access data of the communication interface, such that the access data is wirelessly transmitted to the wireless measurement sensor,
wherein the wireless measurement sensor is configured to:
measure one or more measurement signals influenced by the machine component being moved according to the motion pattern associated with the access data;
evaluate the measurement signals to determine the access data of the communication interface; and
wirelessly connect to the communication interface via the determined access data.

15. The machine of claim 14 ,
wherein the machine controller is configured to move the machine component relative to the wireless measurement sensor according to a motion program modulated with the access data.

16. The machine of claim 15 , wherein the machine controller is configured to automatically generate the motion program to cause the machine component to move.

17. The machine of claim 14 , wherein the machine controller is configured to:
receive the measurement signals transmitted from the wireless measurement sensor via the communication interface; and
determine an actual attachment position of the wireless measurement sensor on the machine by correlating the measurement signals with respective reference measurement values for multiple attachment positions stored in a memory of the machine controller and selecting the actual attachment position from the multiple attachment positions based on a result of the correlation.

18. The machine of claim 14 , wherein the motion pattern comprises one of a spatial motion pattern, a temporal motion pattern, and a spatial and temporal motion pattern.

19. The machine of claim 14 , wherein the machine component comprises one of:
a workpiece tool or workpiece table which is movable along axes of an NC (numerical control) machine system, and
a laser machining head which is movable along axes of a laser processing machine.

20. The machine of claim 14 , wherein the access data comprises at least one of:
Wi-Fi ESSID (Extended Service Set Identification) and Key, or
BT (Bluetooth) Host MAC (media access control) address.
