AUTOMATIC SENSING ALARM SYSTEM AND METHOD USING INFRARED RAY SENSOR AND BLUETOOTH FOR PREVENTING INVASION OF PIRACY

摘要

PURPOSE: A pirate intrusion sensing alarm system and a method capable of using an infrared sensor and a Bluetooth are provided to act quickly on a danger of being kidnapped by finding the intrusion of a vessel at an early stage and automatically operate the alarm system. CONSTITUTION: An intrusion sensing alarm system includes an infrared sensor(1), a Bluetooth bar code(2), a Bluetooth barcode reading sensor(3), and a control unit(4). The infrared sensor senses an object by using the infrared ray. The Bluetooth barcode reading sensor recognizes the Bluetooth bar code. The infrared sensor and the Bluetooth barcode reading sensor are installed together at an identical place and one or more than two are secretly installed in an intrusion prediction area. The control unit receives a signal of the infrared sensor and the Bluetooth barcode reading sensor. If the Bluetooth bar code information is not received from the Bluetooth barcode reading sensor within a certain amount of time after the object is sensed in the infrared sensor, the system recognizes as a status that an intruder is in the vessel.
