Abstract

A method of configuring power tool electronics in a hand-held power tool (10) having sensor means (20) for acquiring measurement data, a control unit (50) for processing measurement data and for controlling power tool functions, and a data transmission unit (30), includes transmitting data between the data transmission unit (30) and an evaluation location (62) by means of a mobile wireless network, with the power tool electronics being awakened from a quiescent mode (70) and activated at a time stored as a time parameter in a control program, retrieving a configuration file provided by the evaluation location (62) by the data transmission unit (30) via the mobile wireless network, and checking the response received from the mobile wireless network to determine whether or not it contains a new configuration file. If a configuration file was received, the parameters contained in the configuration file are implemented (77) in the control program for the power tool electronics. The power tool electronics is then returned to the quiescent mode (70) again.

Claims

1. A method of configuring power tool electronics in a hand-held power tool (10) including sensor means (20) for acquiring measurement data, a control unit (50) for processing measurement data and for controlling power tool functions, and a data transmission unit (30), with data transmission being carried out between the data transmission unit (30) and an evaluation location (62) by means of a mobile wireless network, wherein

in a first step (71), at least the control unit (50) and the data transmission unit (30) of the power tool electronics are awakened from a quiescent mode (70) and activated at a time stored as a time parameter in a control program,

in a subsequent, second step (72), the data transmission unit (30) enters into a wireless digital data communication with a mobile wireless network and, via the mobile wireless network, retrieves a configuration file provided by the evaluation location (62),

in a subsequent, third step (73), the data transmission unit (30) receives via the mobile wireless network a response which can contain a new configuration file,

in a subsequent, fourth step (74), at least one of the data transmission unit (30) and the control unit (50) check(s) whether or not a configuration file was received and, if a configuration file was received, implements (77) parameters contained in the configuration file in the control program for the power tool electronics,

and, in a further subsequent step (76), the data transmission unit (30) and the control unit (50) are returned to the quiescent mode (70) again.

2. A method according to claim 1, wherein the data transmission between the evaluation location (62) and the data transmission unit (30) is carried out indirectly by means of SMS.

3. A method according to claim 1, wherein the data transmission between the evaluation location (62) and the data transmission unit (30) is carried out directly via a connection established between the data transmission unit (30) and the evaluation location (62) by the mobile wireless network.

4. A method according to claim 1, wherein in a fifth step (75) taking place between the fourth step (74) and the further step (76), the data transmission unit (30) carries out a data transmission at least of measurement data from the control unit (50) to the evaluation location (62) via the mobile wireless network.

5. A method according to claim 1, wherein at least one of control programs and control program parts are transmitted, in addition to the parameters, from the evaluation location (62) to the data transmission unit (30) with the configuration file.

6. A method according to claim 1, wherein a position determining device (40) for global positioning is provided in addition to the data transmission unit (30), wherein the position data determined by the position determining device (40) are transmitted by the data transmission unit (30) along with the data transmission to the evaluation location (62).
