Device for measuring circular arc kinetic energy and system for measuring dragging force using the device

A dragging force measurement system, comprising:

• a kinetic energy measurement device configured to measure a magnitude of a force generated at an end portion of an electric door in a closing operation of the electric door;
• a vector value extraction module configured to separate the magnitude of the force measured by the kinetic energy measurement device into a vector value;
• and
• a determination reference value setting module configured to set a dragging force determination criterion by measuring a force and energy variation based on the vector value extracted by the vector value extraction module,
• wherein the kinetic energy measurement device comprises:
• an impact energy measurement unit configured to measure impact energy generated in the closing operation of the electric door, and
• a guide unit configured to support the impact energy measurement unit at a point on an opening or closing trajectory of the electric door.
