Abstract

The invention relates to a method for detecting the presence of stone crushing tools on earthmoving machines, wherein at least one RFID tag (5) is arranged in the tool (3, 4) executing an at least periodic radio communication (7) with a reader (11). The interruption and/or absence thereof generates an alarm signal as an indication of a non-functioning or broken-off tool.

Claims

1. A method for detecting the presence of stone crushing tools on earthmoving machines, comprising:

providing at least one RFID tag (5), which has at least periodic wireless communication (7) with a reader (11), in the tool (3, 4), and generating an alarm message when said at least periodic wireless communication is interrupted and/or stopped.

2. The method according to claim 1, wherein the RFID tag is installed in the adapter plate (15) for mounting the tool (3, 4).

3. The method according to claim 1, wherein the reader (11) is installed in the earthmoving machine (1).

4. The method according to claim 1, further comprising providing an acceleration sensor (6) in or on the tool (3, 4), analyzing acceleration values of the tool, and transmitting the acceleration values from the acceleration sensor (6) to the reader (11) by wireless communication with the RFID tag (5).

5. The method according to claim 4 further comprising detecting a number of working cycles with the analysis of the acceleration values of the acceleration sensor (6).

6. The method according to claim 4, further comprising detecting the presence of the tool on the earthmoving machine (1) with the analysis of the acceleration values of the acceleration sensor (6).

7. The method according to claim 4, further comprising detecting functionality of the tool on the earthmoving machine (1) with the analysis of the acceleration values of the acceleration sensor (6).

10. A device for carrying out the method according to claim 1, the device comprising at least one RFID tag (5) installed in the tool (3, 4) to perform at least periodic wireless communication (7) with a reader (11), and optionally, an acceleration sensor (6) installed in or on the tool (3, 4), and transmitting acceleration values to the reader (11) by wireless communication with the RFID tag (5), wherein the reader (11) is installed in or on the earthmoving machine (1), and at least one PC (12) and display (10) for output of the alarm message are installed in the cab (9) of the earthmoving machine (1).

11. The method according to claim 2, wherein the RFID tag is installed in the adapter plate (15) for mounting the tool (3, 4).

8. A device for detecting the presence of stone crushing tools on earthmoving machines for detecting the function and/or presence of stone crushing tools on earthmoving machines, comprising at least one RFID tag (5), which performs at least periodic wireless communication (7) with a reader (11) installed in the tool (3, 4), and an acceleration sensor (6) is installed in or on the tool (3, 4), and transmitting acceleration values to the reader (11) by wireless communication with the RFID tag (5).

9. A device for detecting the presence of stone crushing tools on earthmoving machines for detecting the function and/or presence of stone crushing tools on earthmoving machines, comprising at least one RFID tag (5) installed in the tool (3, 4) to perform at least periodic wireless communication (7) with a reader (11).
