Abstract

In daily life we come to know that in newspapers about many tamil fishermen being caught and put under Sri Lankan custody and even killed. The sea boundary among the countries is not easily recognizable, which is the main reason for this cross border cruelty. Here we have proposed a system using embedded system which safeguards the fishermen by acquainting the country border to them by using RF transmitter and receiver ,Global Positioning System (GPS) and Global system for mobile communication (GSM).To find the receiving signal of the fishing boat or vessel from the RF transmitter (Which located at port), using RF receiver. We can find the current latitude and longitude values and is sent to the microcontroller unit by means of GPS. The Current signal strength can be obtained by comparing the present values with the predefined value by using control unit. Then from the result of the comparison, this system will gives an indication to the fishermen that they are about to reach the nautical border. If the fisherman overlooks the warning or fail to see the instruction display and keep on navigating, and if the boat enters the zone nearer to the restricted zone the alarm will turn on and the engine stops, the alarm will make continues to beep.
