In an electric screwdriver management system according to the present invention, a plurality of slave stations capable of exchanging data with a master station are respectively connected to a plurality of electric screwdrivers. The slave stations comprise: a receiving means for obtaining a setpoint values group from the master station, the setpoint values group comprising at least one setpoint value that is preset in accordance with a performance characteristic of an electric motor used in the electric screwdriver; a storing means for the setpoint values group; a detection means that acquires an electric signal that changes in accordance with an output torque of the electric screwdriver; a calculation processing means that performs a comparison operation between a calculated value acquired on the basis of a value of the electric signal and a pre-obtained setpoint value; and a switch that electrically connects and disconnects a drive power supply circuit to the electric screwdriver on the basis of an output result from the calculation processing means. At least a T/U setpoint value corresponding to a torque value when a screw being screwed by the electric screwdriver is secured in a screw hole is included in the setpoint values group, wherein the drive power supply circuit is disconnected when the calculated value reaches the T/U setpoint value. |
