POWER TOOL CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a power tool control system which surely performs communication between a center device and a power tool via a network.

SOLUTION: When the power tool 1 is held by a holder 3, a microswitch 35 of the holder 3 is turned on and a contact ON signal is transmitted to the center device 2. A control part 201 of the center device 2 receiving the contact ON signal detects that the power tool 1 is placed in the holder 3 and transmits an information request signal to the power tool 1 via the network 4 and the holder 3. The power tool 1 reads the number of revolutions of a motor 102 detected from a time when the power tool 1 is held previous time till a time when the power tool 1 is held this time, torque and accumulation driving time together with an identification number of the power tool 1 and an identification number of a battery 104 from a storing part 109, and transmits them to the center device 2 via the network 4 and the holder 3.
