PURPOSE: A general sewing machine automation system using a lining thread detecting device is provided to improve convenience for using by controlling a sewing machine motor, and to reduce manufacturing costs. CONSTITUTION: A general sewing machine automation system using a lining thread detecting device detects conditions of an upper thread and materials for sewing regardless of thickness and colors of an upper thread. When upper thread detection SW(21), raw material detection SW(22,23), additional CAD task SW are inputted on I/O interface of unmaned automation device(40), a preparing signal is inputted to a central processing unit. When a motor of a motor drive(50) is activated, a sewing machine(10) is operated.
