Abstract (en)
[origin: DE10127821C1] The screwdriver operating device has an electrochemical storage battery (A), an electric motor (M), a switched coupling (K) with a switch contact operated upon reaching a given torque, a control (6) for detection and transmission of operating data for the screwdriver and a base station (7) receiving the operating data via a radio transmission path. The control has a microcontroller unit (L1), coupled to a motor contact and the switch contact of the switched coupling and connected to a radio transmitter (TX1) and a radio receiver (RX1) for bidirectional data transmission, the base station similarly having a microcontroller unit (L2), a radio transmitter (TX2) and a radio receiver (RX2). An Independent claim for a system for operation of an electric screwdriver is also included.
