Abstract

The invention relates to a position determination and regulation system for working devices arranged on the working arms of mobile machine-tools. Said system comprises at least one sensor and an emission/reception unit. The determination and transmission of position co-ordinates (x, y) and/or an incline (φ) of the working device between the at least one sensor and the emission/reception unit are carried out in a contact-free manner.

Claims

1. System for detection and control of operating mechanisms (3) disposed on operating arms (2) of mobile machines (1), comprising at least one sensor (4) and a transmitting/receiving unit (5),

characterised in that

the transmission and detection of position coordinates (x, y) and/or of an inclination (φ

) of the operating mechanism (3) between the at least one sensor (4) and the transmitting/receiving unit (5) is effected without contact.

2. System according to claim 1,

characterised in that

the at least one sensor (4) is configured as an active sensor (4).

3. System according to claim 1,

characterised in that

the at least one sensor (4) is configured as a passive sensor (4).

4. System according to one of the claims 1 to 3,

characterised in that

the at least one sensor (4) is disposed in the operating mechanism (3).

5. System according to claim 4,

characterised in that

signals emitted via a control lever (10) of the machine (1) can be transmitted by the transmitting/receiving unit (5) and the at least one sensor (4) to the operating mechanism (3).

6. System according to one of the claims 1 to 5,

characterised in that

at least one further sensor (4) is disposed in a hydraulics unit (6) of the operating arm (2).

7. System according to claim 6,

characterised in that

the sensor (4) disposed in the hydraulics unit (6) transmits a pressure signal (p).

8. System according to one of the claims 1 to 7,

characterised in that

the system has an amplifier unit (8).

9. System according to claim 8,

characterised in that

the amplifier unit (8) is configured in the form of at least one transmitting/receiving unit (5).

10. System according to claim 8 or 9,

characterised in that

the amplifier unit (8) is disposed on the operating arm (2) of the machine (1).

11. System according to claim 8 or 9,

characterised in that

the amplifier unit (8) is disposed separately from the machine (1).

12. System according to one of the claims 8 to 11,

characterised in that

the amplifier unit (8) is in direct visual contact with the at least one sensor (4) and the transmitting/receiving unit (5).

13. System according to one of the claims 1 to 12,

characterised in that

the transmission of the signals is effected on the basis of a radio signal, in particular on the basis of microwaves.

14. System according to one of the claims 1 to 13,

characterised in that

in addition physical variables (p) can be transmitted via the system to the transmitting/receiving unit (5).
