24/7 Border Security System
[attachment=668]
Introduction
Motivation
The Project 24/7 Border security system is used for remote monitoring of a certain area where man power is costly. This project helps to especially safeguard lives of soldiers. Our country is suffering from intense security issues these days. Every time we switch on our television we hear some bomb blast, target killing or an intruder in a facility. We as Engineer’s should try to safeguard the lives of army men as well as people by technically improving the security system.
Border security is one of the most dangerous things for soldiers. It’s the area where we need 24/7 monitoring. Work becomes still complicated & dangerous if there is obstacle between two nations. At these conditions, soldiers risk their lives. If sudden attack happens, they will be shocked and can’t counter attack. Also it takes a minute or two to analyze multiple moving targets by normal men. During night, more alert is needed. The solutions to these problems are given in our security system.
The thought behind this project was just a try to give a sense of security and safety to the men who ensure our safety. Obviously no one can cheat death, but the feel can make a lot happy, peaceful at their jobs and hardworking as well. And how would that happen? It’s that the project aims to make people able to use guns without putting their own life in danger.
Technical Background
This project uses various concepts like digital communication, image processing, microcontroller concepts to design prototype. For communication, we use wireless module or microcontroller MSP430G2553. For image processing part computer runs codes to detect object motion & generates appropriate signal. The decision making part is done with microcontroller again. It is interfaced to drivers to drive motors. The wireless module frequency is 2.4GHZ in ISM band. The open CV is a free source library. It is used with MSDN library for image processing and hardware control. IAR & CCS are used for hardware programming. The driver ICs DRV8821 & L293D are easy to use and more efficient.
Goal of your Project
The project aims at “Border Security Sytem” design for military applications, that is we control gun movement from a far distance with the help of computer. This helps soldiers to use gun without risking their lives. The system was operated in wired mode. The expected behavior is movement of motors of vertical & horizontal motion with the ‘mouse click or key press’. When we pressed keys, the ASCII values of button is sent serially to MSP430G2553. It is programmed to move motors. In object tracking mode, until centroid matches with respect to central crosshair, probing signal is sent continuously to MSP430G2553. In turn, MCU drives the motors via DRV8821 board. The stepper motor driver & L293D are signaled by MCU as per requirement. The mode pins in DRV8821 is set to ½ mode. It can be changed based on required resolution. The same process is repeated for “wireless mode” of operation. Everything is nicely achieved.
Software Implementation
Image processing
One of the major tasks in project development was creating a user interface to enable the user to view the live video feedback from onboard wireless camera and easily control the movement of the gun using the keyboard or object tracking.
For the development of user interface there were several options available like Visual Basic, C++, and MATLAB etc. Also for image processing part MATLAB or OpenCV could be used. Data communication can be done through USB, parallel port or serial port.
KEYBOARD MODE
In this mode we control the movement of gun mount using the keys present in keyboard. Four keys control the direction of left, right, top, bottom movement of gun mount and one key for firing. After generation of crosshair, keyboard listener function checks for any keyboard press. If any press is detected the key listener function is called. This function stores the ASCII value of the key pressed. Using these values in a switch case statement we check for the key pressed. Depending on the pressed key, control signals are sent. We use five different characters for each keys and for each key pressed we send a character serially to the wireless transmitter. After that the next frame is loaded into memory and process carries on for each frame in a loop. The receiver on the other side receives serial data and sends it to the microcontroller which in turn generates appropriate step signals to the stepper motor which in turn moves the gun and camera.
. Conclusions
The goal of project was to make a prototype of gun mount which can be controlled by computer for monitoring purpose. Goal is achieved. The mount can be configured in various modes. They are wired mode, wireless mode. In this we have again manual mode & object tracking mode of operation. The results were nicely matching with calculated values. We got the one of the best PCB for stepper motor control as well as DC motor control. Using that board we can control 2 stepper motors & 2 DC motors. This innovative idea is implemented with very less investment, just for $59! In future, military people can use this prototype for security purpose. This model is basic version of future heavy weapon.
