IMPORTANCE OF MINIATURIZED DEVICES

Miniaturization is the creation of ever- smaller scales for mechanical, optical, and electronic products and devices. Miniaturization is a continuing trend in the production of such devices.

Miniaturized items more preferred than bigger and bulkier items because they are easier tohandle, optimize and much more convenient touse and control.

IMPORTANCE OF MINIATURIZED SURVEILLANCE DEVICES

Why Do We Need Surveillance?With the ever-advancing technology field come many conflicting opinions about what should and should not be used. One of the pieces of technology that causes a bit of controversy is surveillance based equipments which are placed in public. Although some believe that they should not be used, on the other hand these can be an important part of society and can be quite helpful in prevailing various wrong deeds without risk of precious human life.

Palm-sized nano copter micro-machines are now being used to collect intelligence in

Afghanistan which lessens the life threats faced to the security personals.

IMPORTANCE OF MINIATURIZED SURVEILLANCE DEVICES

Public SafetySurveillance can be used to keep an eye out for any crimes that are in progress or they can be stopped before they even start.

Can Help Catch a CriminalIf a crime is committed and there is a surveillance camera, there is a good chance that the authorities will be able to get a viable image of the criminal.

Sense of SecurityFor some people, knowing that surveillance equipments are in certain areas can help create a sense of security. No one wants to fear having to go into an area or feel as though he/she is not safe.

IMPORTANCE OF MINIATURIZED SURVEILLANCE DEVICES Crime Prevention

Some businesses and authorities may place surveillance equipments in areas in hope that it will prevent crimes from being committed in the first place.

EvidenceIn court, the footage from the surveillance equipments that captured a crime can be used as evidence against the accused. Without the footage, there may be little to no evidence to go on and the criminal could go free. In some cases, the footage may also help prove the innocence of someone who was accused of a crime, but did not commit it.

CURRENT TREND OF MINIATURIZED SURVEILLANCE DEVICES

Wireless automation:-the current trends for surveillance is to obtain the visual and recording proof by means of wireless technology.The common term for such miniaturized devices is “drones" which can be used for surveillance as well as some bit of offensive actions.

WIRELESS CONTROL OF MINIATURIZED MOBILE VEHICLE FOR INDOOR SURVEILLANCE

In the current project we favored to proceed current trends for surveillance.

The project is a practical based work, which includes a real time interface between the drone (surveillance vehicle) and the controller’s android phone through Bluetooth technology.

POSSIBLE APPLICATIONS The project can be used for various

purposes however few of them are listed as example:

Mine detection. Surveillance. Assisting security personals etc

10

PROJECT FEATURES The project incorporates three major

hardware / software sections.

I. Android Operating System

II. Bluetooth moduleIII. Arduino

microcontroller

11

ANDROID OPERATING SYSTEM A software platform and operating system for mobile

devices. Based on the Linux kernel; Developed by Google and later the Open Handset Alliance

(OHA) Allows writing code in the Java and C/C++ language; Put simply, Android is a combination of three components: A free, open-source operating system for mobile devices. An open-source development platform for creating mobile

applications Devices, particularly mobile phones, that run the Android

operating system and the applications.

12

BLUETOOTH Wireless technology for short-range

voice and data communication Low-cost and low-power Provides a communication platform

between a wide range of “smart” devices.

Not limited to “line of sight” communication.

Bluetooth module is the most reasonable and convenient way to go wireless. This module allows us to extend our serial interface by means of wireless communication, so any program running on our hand held device feels like it is controlling a local serial port. The four pins are Tx, RX, GND and +5V. The input Supply voltage should be 3.3V - 6 V.

SYSTEM DECISION COMMAND FLOW The command detection function is

performed by the microcontroller. The Android application on mobile phone

sends the character to Bluetooth module which forwards the character to Ardunio microcontroller.

The Arduino microcontroller receives that character as a numerical value and then matching the condition send pulse on the desired port.

The Pulse will continue to transmit until the button on android application is in contact. The activating actuators are designed by continuous pulse on sent via android phone buttons.

Any input switch is released; it will interrupt the main function loop of the microcontroller. Then, the microcontroller will deactivate the relay and stop the ongoing task.

18

GUI OF ANDROID CONTROL APPLICATION

Android GUI is designed by a user-friendly interface.

The four directions indicated the desired control for the MSV that is connected to the system.

Control board “Connect to BT‟ button is performed to establish connection to main control board by Bluetooth. Phone “Connect to BT‟ button performs to establish connection between Android GUI and Bluetooth module.

When the connection is established, Android GUI acts as the control panel between main board and phone. All the data received from main board will be forwarded to the phone. Also, the data sent from phone will be forwarded to main board.

19

HARDWARE DESIGN The connections

for duplex communication channel of programmable controller are displayed in figure.

20

HARDWARE DESIGN The relay connection

circuit is further listed in figure. We have two modules of these Circuits, one for mobile surveillance vehicle (MSV)’s movement direction and another for front and back Light Controlling, through the listed circuit the vehicle can perform basic functions of vehicle movement (forward, reverse, left and right turns) with 360o rotation with two front and backlights.

21

CONCLUSION AND FUTURE APPLICATIONS

In conclusion, the vehicle is a low cost system which is designed to withstand any terrain and surrounding,

Implementation of wireless Bluetooth connection in control board allows the system install in more simple way.

Flexible types of connections are designed as backup connections to the system. The connected GUI is synchronized to the control board. They indicate the real-time switches status.

The system is designed in user-friendly interface. The easy to use interface on Android GUI provides simple control.

For future work, the android GUI will be implemented with speech recognition voice control.

The system will also be equipped with a wireless camera which will transmit the real time images.

The vehicle will also be equipped with a highly sensitive collision avoidance system so that it can be implemented as an autonomous vehicle.
