MARITIME BORDER ALERT BY LOCATION

MONITORING USING GPS FOR PROTECTION OF

FISHERMEN

Shirly Mini J&

Shree Krishna Priya JECE final year

Abstract

To guide the fisher man along the border and to inform the Indian Navy immediately about the entry of fishermen into the Sri Lankan maritime border the proposed system uses a administrator database at the Navy side to which all the fishermen must be registered and NOKIA 6600 mobile phone to be owned by the fishermen to access the GPS for finding the location of the fishermen, to send message to the Indian Navy about the whereabouts of the fishermen, who can warn the fishermen through message to come back to our side.

Fisheries in Tamil Nadu• Census 2013, there are 3,288 marine fishing

villages .• The total Marine fisher folk population was about

4 million comprising in 864,550 families. • 38% marine fisher folk were engaged in active

fishing with 85% of them having full time engagement.

• 63.6% of the fisher folk were engaged in fishing and allied activities.

• The problem lies in the fact that India and Sri Lanka share a 400 km maritime border.

What already exist?An android app by Dr.Swaminathan research

centre to govern the fishermen along the sea

FISHER FRIEND PROGRAMME

• Fisher Friend Mobile Application• Shore to Shore Approach• Risk Reduction and Enhanced Fish Catch

What is the disadvantage?

•We cannot expect all the fisherman to own an android mobile phone•Even if they own a android mobile phone they must be taught how to use it ?•Since the fishermen needs keep track by themselves sometimes the alert falls on deaf ears •Battery life??

What have we suggested to use?

• NOKIA 6600 or any phone that contain GPS facility

• PostgreSQL(a database for storage of related information)

• Microcontroller for computation purposes

GPS in Nokia 6600

Advantages of NOKIA 6600• GPS system which can be used

to track the location of the user (fishermen)

• Cheap• Language compatibility

PostgreSQL

• An object-relational database management system (ORDBMS) with an emphasis on extensibility and standards-compliance.

• As a database server, its primary function is to store data, securely and supporting best practices, and retrieve data when required.

Role of PostgreSQL

Related information of fishermen such as their mobile number, address, district, state are stored in the database

Advantage • If a new fisher man

registers himself in the network, then the database supports addition as required.

HOW WE DO IT?Register fisher

man and mobile phone

MARITIME BOUNDARY BETWEEN INDIA AND SRI LANKA

The current positions are compared with already stored latitude and longitude of countries boundary.

Positions Latitude Longitude • Position 1 12° 05'.0 N 82° 03'.0 E • Position 2 12° 05'.8 N 82° 05'.0 E • Position 3 12° 08'.4 N 82° 09'.5 E • Position 4 12° 33' 0 N 82° 46'.0 E locations. Even more positions can be stored to

increase the accuracy of the system

Computation in Microcontroller

• These points should be stored in microcontroller. Thus vessel crossing the border is being calculated.

• The current position received from GPS is stored as S1 (latitude), S2 (longitude). The latitude S1 is compared with stored latitudes.

Computation in Microcontroller

• If latitude match, then adjacent latitude and longitudes (X1, Y1 and X2, Y2)

(Y-Y1)/(Y2-Y1) = (X-X1)/(X2-X1)

By simplification, we get ax + by = c• Now, S1(x) and S2(y) are substituted in above

equation of line and the position of fishermen are calculated.

Alert system• Inside border: Green color indication

in the database• Near the border: Red color indication

in the database• After crossing the borderFirst layer alert: Alert given to the

administrator side and to the fisherman through SMS

Second layer alert: Navy personnel should govern the fisherman to the right direction

Advantages of the system

A continuous monitoring of fishermen along the maritime border with navy assistance

• Even if the alert is missed by the fishermen the navy can go for bringing the fishermen inside the border

• Saves lives of fishermen• Saves from the property loss of fishermen • Saves the country from unwanted dispute with

the neighbouring nations

Disadvantages

• Battery life problem exist as fishermen go out for fishing for more than a day

• There is a need to carry mobile phones for monitoring as we do not have automated boats used for fishing in India

• The reach of mobile signals in far sea needs satellite assistance which increases the cost of the project

FUTURE WORK

• It can be used in the Tamil Nadu-Sri Lanka maritime border

• Can also be used in Gujarat-Pakistan border where the same kinds of problem exist.

• Can be incorporated for maritime border protection from terrorists.

Conclusion

The proposed system uses the GPS to monitor the position of the fishermen and update the navy with the position of the fishermen and warn them when they go out of the Indian maritime border
