MARINE COASTAL PERIMETER INTRUSION DETECTION SYSTEM
ABSTRACT
In November last year, 10 heavily armed terrorists who India says came from
Pakistan sailed into Indian waters by giving the slip to Coast Guard officials with the help
of fake identity cards
Upon hearing these kind of news one is forced to think about the various means
and options to contribute in the effort to stop the unauthorized entry in our national
waters. This will not only strengthen the security of the country but will also give a sense
of being secured to the residents.
INTRODUCTION
Here we propose a mechanism in which every boat entering into national waters
and exiting into international water will be required to undergo a scrutiny check and
will be accounted for. For this we suggest that there will be only limited points of entry
and exits and all other points will be continuously monitored for any unlawful entry and
exit. Here the boat will be identified by means of RFID tags. Also at these entry and exit
points we propose to capture an image of the captain of the boat by means of a Webcam
and will be stored for later references. For all other points there should be continuous
patrolling of the coastal guards. However, India has a coastline of 7,517 km and has 13
coastal states bound by the Indian Ocean on the south, the Arabian Sea on the west, and
the Bay of Bengal on the east, so it becomes extremely difficult to monitor the entire
coastline by patrolling. To counter this problem we propose a mechanism (detectors) for
onnecting the entire coastline with a reflective type sensor (PIR) (Passive Infra Red)
or LOS (Line Of Sight) LASER (Light Amplification through Stimulated Emission of
Radiation) sensors.
MAIN COMPONETS
1. Detector
These ‘detectors’ will be continuously monitoring the coastline and will inform the nearest patrolling coastguard ship of any intrusion that is detected. This will be achieved by sending messages to the coastguard ship by RF transmitter. In the proposed model we will be using a transceiver with 150ft of data transmission, however in the real life scenario we will be required to send information over several miles.
If this mechanism is introduced it will not only stop the infiltration by the
terrorists but smuggling of drugs and other items.
Considering another scenario, the coast guards ships which are supposed to keep patrolling might be required to enter international waters legally. But the moment they try to do so, the sensors will immediately get activated and will give alarm in these cases too.
To solve such cases we will be connecting a receiver in the ‘detectors’ which will be used to deactivate the ‘detectors’ when the legitimate boats needs to be crossing the borders and can be reactivated once the transit is completed.
2. RFID Reader
The RFID reader consists of a 125 KHz oscillator that allows interrogation of
the RFID transponder. The information in the transponder is relayed via the reader to a
PC through a serial interface. The RFID transponder will transmit the ID codes without
making physical contact with the reader. This non-contact method of ID code reading
will allow non-invasive, non-intrusive identification process. Additionally, the RFID
transponder has the advantage of being immune to dust, dirt, grease, paint and any other
contaminant found in everyday life that generally affect older methods of identification
like barcodes and human readable lettering.
