In everyday life we learned that many Tamil fishermen were captured and subjected to Sri Lankan custody and even killed. The maritime border between countries is not easily identifiable, which is the main reason for this cross-border cruelty. Here we have designed a system that uses an embedded system that protects fishermen by notifying them of the country's border using the Global Positioning System (GPS) and the Global System for Mobile Communication (GSM). The control unit then finds the current position by comparing the current latitude and longitude values with the preset value. Then, from the result of the comparison, this system knows the fishery that are about to reach the nautical border. The area is divided into four zones: normal zone, zone of alert, zone next to restricted zone and finally restricted zone. If the boat is in the normal area, then the LCD shows the normal area. So you can make it clear that the boat is in the normal area. If you move further and reach the warning zone, the LCD will display the warning zone. If the fisher ignores the warning or does not see the screen and moves further, and if the boat enters the zone closest to the restricted zone, the alarm will be on and the motor speed of the boat will be automatically controlled by 50%. If the fisherman does not react to the alarm and moves more, then the boat will enter the restricted zone, the alarm will continue to sound as before, and once it touches the restricted zone, the boat engine is triggered by the supply control of fuel to the engine.
The same data is sent to the fisherman's mobile and simultaneously the same data is sent to maritime safety. An EEPROM is used to store the data, received by the GPS receiver. The hardware that interacts with the microcontroller are LCD screen, GSM modem and GPS receiver. GPS (Global Positioning System) is increasingly used for a wide range of applications. It offers reliable positioning, navigation and synchronization services to users around the world continuously in any type of weather, day and night, anywhere or near the Earth. 28 satellites inclined at 55 ° to the equator orbit the Earth every 11 hours and 58 minutes at a height of 20,180 km in 6 different orbital lanes and each of these satellites has up to four atomic clocks on board. All we need is a precise watch. When comparing the time of arrival of the satellite signal with the clock time on board, at which the signal was emitted, the latitude and the longitudinal degree of the ship's location are determined. The current design is an embedded application that will continuously monitor a moving ship and once the boat goes beyond the level of the defined layer, the particular operation will be performed. For this an AT89c51microcontroller is interconnected in series to a GSM MODEM AND GPS receiver.
Global Positioning System (GPS) satellites transmit signals from the space that GPS receivers use to provide three-dimensional location (latitude, longitude, and altitude) plus precise time. GPS receivers provide reliable positioning, navigation and synchronization services to users around the world continuously in any type of weather, day and night, anywhere or near the Earth. This ultra sensitive GPS receiver can acquire GPS signals from 65 satellite channels and output position data with high precision in extremely challenging environments and under poor signal conditions due to its active antenna and high sensitivity. The tracking sensitivity of the -160dBm GPS receiver enables continuous position coverage in almost all application environments. The output is 9600 baud rate serial data which is standard NMEA 0183 v3.0 protocol that offers industry standard data messaging and a set of commands for easy interface mapping software and integrated devices. This project was built to provide GPS locations to fisherman men who are facing risks during sailing, maximum risks occur for fishermen in situations where they travel on a boat for fishing. In some situations they should not move after a certain point and should not enter the area of other countries. There is a real need in designing a system that can track the vehicle and display geographic location, there alerting fishermen. This project uses a GPS modem and a microcontroller. The GPS data is continuously monitored and fed to the microcontroller. The controller then sends the data to a 16x2 LCD. This project uses a regulated 5V, 500mA power supply.
