UNMANNED SURVEILLANCE SENSOR USING AN IMAGE SENSOR, CAPABLE OF PREVENTING AN FALSE ALARM OF A THERMAL SENSOR

摘要

PURPOSE: An unmanned surveillance sensor using an image sensor is provided to prevent costs and damage due to a false alarm by decreasing a false alarm ratio.;CONSTITUTION: The movement of an object is sensed by using an image sensor and a DSP step(S200). The sensed image data is transmitted. An infrared controller controls the external brightness(S120). The data is transmitted to the DSP step. The transmitted data is preprocessed(S20). The data is transmitted by a serial transmission step(S60) only when the movement of the object is sensed. The data is transmitted by a network transmission step(S80) only when the movement of the object is sensed. A contact signal is transmitted to a main device of the unmanned guard instrument by a contact switch step(S70).;COPYRIGHT KIPO 2010
