DIGITAL DOORLOCK WITH FLEEING PREVENTION A SECURITY FUNCTION BY USING SECURITY SYSTEM AND ITS CONTROLLING METHOD

摘要

A security system using a digital doorlock with a fleeing prevention function and a control method thereof are provided to raise a security level of the security system by preventing an intruder from running away through an opened door. An absence mode setting signal is inputted by an input unit(120). A sensor(110) detects an intruder. When a sensor signal is received from the sensor after the absence mode is set, a security controller is forcefully switched into an alarm mode, transmits an emergency message through a communication network, and provides an alarm generation signal to an output unit(140). When the sensor signal is received from the sensor after the absence mode is set, a main controller(130) is forcefully switched into the alarm mode, provides the alarm generation signal to the output unit, and provides a lock signal for locking a dead bolt. The output unit generates alarm sound. A dead bolt locking unit(150) provides a forceful locking signal according to the lock signal from the main controller. A driving unit(160) forcefully locks up the dead bolt, such that the dead bolt is closed according to the forceful locking signal.
