Method for documenting at least one work step, and hand-held tool

1. Method for documenting at least one work step with a hand-guided tool, wherein the hand-held tool has at least one camera, in particular mechanically connected to the tool, comprising the steps:

receiving information from a building information system in defining a work step to be performed based on information specific to the building stored in the building information system;

activating the camera and capturing images of the work step performed with the hand-held tool and generating image data associated with the work step;

recording further parameters pertaining to the work step using at least one other sensor arranged in or on the hand-held tool and generating sensor data pertaining to the work step;

generating device data pertaining to the hand-held tool;

transferring the generated image data, sensor data and/or device data to a computer and at least temporarily storing the image data, sensor data and/or device data in the computer; and

creating documentation of the at least one work step using the image data, sensor data and/or device data stored on the computer.

2. Method according to claim 1 , comprising activating the camera by moving the hand-held tool, switching on the hand-held tool and/or unfolding the camera out of a housing of the tool.

3. Method according to claim 1 , wherein provision is made for recording further parameters pertaining to the work step, wherein the recording of a date, a time, a material of an object processed with the tool, a type and size of a tool insert used, a rotational position of a tool insert relative to the tool, a drill hole depth or screw-in depth, a rotational speed of a tool insert used with the tool, a torque of a tool insert used with the tool, a position of the tool and the tool insert in space, a temperature of the tool, a temperature of an environment and/or a temperature of a processed object, a humidity of the environment and/or a humidity of a processed object and/or identification data of an operator of the tool is provided.

4. Method according to claim 3 , comprising acquisition of data by means of a rotation speed sensor arranged in the tool, a torque sensor arranged in the tool, a rotation position sensor arranged in the tool, a position sensor arranged on the tool, a distance sensor arranged on the tool, an optical sensor arranged on the tool, an ultrasonic sensor arranged on the tool, a high-frequency sensor arranged on the tool, a temperature sensor arranged in or on the tool and/or a humidity sensor arranged in or on the tool.

5. Method according to claim 1 , wherein the computer is arranged in the tool, characterized by and further including transferring target data relating to a work step to be carried out with the tool to the computer.

6. Method according to claim 5 , comprising comparing the target data with the acquired image data, sensor data and/or device data belonging to the work step.

7. Method according to claim 6 , comprising generating a warning message or warning signal if a comparison of the target data with the acquired image data, sensor data and/or device data reveals a deviation outside a predefined range, and controlling the hand-held tool with the target data if necessary.

8. Method according to claim 5 , comprising displaying the target data by means of a display device on the tool.

9. Method according to claim 5 , comprising automatically limiting a maximum rotation speed and/or a maximum torque of the tool depending on the target data.

10. Hand-guided tool for carrying out a method according to claim 1 , wherein the hand-held tool has at least one camera, in particular mechanically connected to the tool.

11. Hand-guided tool according to claim 10 , wherein the hand-held tool is fitted with sensors for recording parameters pertaining to a work step.

12. Hand-guided tool according to claim 10 , wherein the hand-guided tool comprises a computer arranged in or on a housing of the hand-guided tool, wherein at least one of generated image data, sensor data and device data are transferred to the computer and at least temporarily stored in the computer.

13. Hand-guided tool according to claim 12 , wherein target data relating to a work step to be carried out are at least temporarily stored in the computer.

14. Hand-guided tool according to claim 12 , further including storing the documentation of the at least one work step in the building information system in association with the information from the building information system used in defining the work step.

15. Method for documenting at least one work step with a hand-guided tool, wherein the hand-held tool has at least one camera, in particular mechanically connected to the tool, comprising the steps:

receiving information from a building information system that defines a work step to be performed based on information specific to the building stored in the building information system;

activating the camera and capturing images of the work step performed with the hand-held tool and generating image data associated with the work step;

recording further parameters pertaining to the work step using at least one other sensor arranged in or on the hand-held tool and generating sensor data pertaining to the work step;

generating device data pertaining to the hand-held tool;

transferring the generated image data, sensor data and/or device data to a computer and at least temporarily storing the image data, sensor data and/or device data in the computer; and

creating documentation of the at least one work step using the image data, sensor data and/or device data stored on the computer.
