Method for monitoring authorized and unauthorized persons within a security perimeter around an apparatus
View Patent ↗The invention relates to the automatic detection of the presence of non-authorized persons in the vicinity of an apparatus of the aircraft type. To this end, the invention comprises equipping persons with radio transmitters for identifying them as authorized personnel. The aircraft are also fitted, such as at the existing PODs, with a transceiver device of a radio identification system of the RFID type for recognition of the persons wearing the radio transmitters. Only the persons who are not authorized in the vicinity of the aircraft initiate an alarm procedure.
1. A method for monitoring authorized persons and unauthorized persons present within a determined security perimeter around an aircraft, comprising:
detecting by a detection system, a person entering the security perimeter of a secured area, wherein the detection system includes at least one sensor in or on the aircraft that detects movement of the authorized persons and the unauthorized persons within the determined security perimeter;
emitting a radio request if movement is detected, wherein the radio request is an interrogation signal for a radio frequency identification (RFID) tag of a radio identification system, the radio request being emitted from a transceiver device in or on the aircraft;
checking an RFID tag reply to the radio request to determine whether access to the secured area is authorized, wherein checking the RFID tag includes verifying data relating to one or more identities, wherein each identity includes individualized authorization rights to access sub-areas of the security perimeter stored in the RFID tag and in a database of the radio identification system; and
activating an alarm procedure where no access is authorized.
2. The method of claim 1 , wherein radio requests are emitted with several transceiver devices positioned at different places in or on the aircraft.
3. The method of claim 1 , wherein checking includes verifying data contained in a RFID tag reply with data stored in a database of the radio identification system.
4. The method of claim 1 , wherein the detection system includes at least one radar, the radar and the transceiver device operating at different frequencies.
5. The method of claim 1 , wherein the transceiver device and the detection system are housed together.
6. The method of claim 1 , wherein the alarm procedure includes activating a video recording of the person detected.
7. The method of claim 6 , wherein the video recording is recorded onto a hard disk onboard the aircraft.
8. The method of claim 6 , wherein the alarm procedure includes automatically transmitting the video recording to a location outside of the security perimeter.
9. The method of claim 8 , wherein the alarm procedure includes communicating an alarm message to a location outside of the security perimeter.
10. The method of claim 1 , wherein the alarm procedure includes activating an audible alarm.
11. An apparatus for monitoring persons authorized and not authorized to be present within a determined security perimeter around an aircraft, comprising:
a detection system, including at least one sensor in or on the aircraft that detects movement of the authorized persons and the unauthorized persons within the determined security perimeter; and
a radio identification system, including a transceiver device in or on the aircraft that emits a radio request, wherein the radio request is an interrogation signal for a radio frequency identification (RFID) tag, the radio identification system further checking an RFID tag reply to the radio request to determine whether access to the secured area is authorized and activating an alarm procedure where no access is authorized, wherein checking the RFID tag includes verifying data relating to one or more identities, wherein each identity includes individualized authorization rights to access sub-areas of the security perimeter stored in the RFID tag and in a database of the radio identification system.
12. The apparatus of claim 11 , wherein the apparatus is positioned on a belly fairing of the aircraft.
13. The apparatus of claim 11 , wherein the detection system includes at least one radar, the at least one radar and the transceiver device operating at different frequencies.
14. The method of claim 3 , wherein data relating to at least one of a time slot for authorized presence or a duration of authorized presence is stored in the RFID tag and in the database of the radio identification system.
15. The method of claim 1 , wherein different sub-areas are distinguished within the security perimeter.
16. The method of claim 1 , wherein the alarm procedure includes initiating a telephone call to a location outside of the security perimeter.
