Border Alert System for Fisherman using GPS and GSM

Abstract

In day-to- day life we hear news about how many of 
fishermen being caught and put under custody and 
even killed across the globe. The sea border between 
the countries is not easily identifiable, which is the 
main reason for this cross-border cruelty. 
Here we are thought of a solution using embedded 
system which protects the fishermen by notifying the 
country border to them by using Global Positioning 
System (GPS) and Global system for mobile 
communication (GSM). We use GPS receiver to find 
the current location of the fishing boat or vessel. 
Using GPS, we can find the current latitude and 
longitude values and is sent to the microcontroller 
unit. Then the controller unit finds the current 
location by comparing the present latitude and 
longitudinal values with the predefined value. Then 
from the result of the comparison, this system aware 
the fishermen that they are about to reach the 
nautical border. The area is divided into four zones- 
normal zone, warning zone, zone near to restricted 
zone and finally the restricted zone. If the boat is in 
normal area, then the LCD displays normal zone. 
Thus, they can make it clear that the boat is in 
normal area. In case it moves further and reaches 
the warning zone, the LCD displays warning zone. 
If the fisherman ignores the warning or fail to see 
the display and move further, and if the boat enters 
the zone nearer to the restricted zone the alarm will 
turn on and the speed of the boat engine 
automatically gets controlled by 50%. If the 
fisherman did not take any reaction about the alarm and move further, then the boat will enter into the 
restricted zone, the alarm continues to beep as before, and once it touches the restricted zone, the 
boat engine gets off by the control of fuel supply to 
engine.
