System For Position Detection

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.

     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 ).

       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

     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.
