Abstract
In this paper an attempt is made to fabricate an imperceptible/ invisible intelligence security system employing auto lock door practice which should distinguish between friend and foe. This is akin to a system which is mandatory to handle the situations resulting from the events like blasts/suicides attacks etc. A unique method of the secretive operated metal sensors system has been presented incorporating initially the Infra Red Transmitter and Infra Red Receiver at the gates for closing/opening purpose and then after the access to scan a human body instead of a having massive scanning system installed at the entrance gate of an organization/establishment which is even indiscernible/ invisible to a human eye. This system will automatically scan a human body while passing above these metal detectors installed beneath the ground. In the event of possession of any kind of metal/weapon or any radioactive material the gate fitted with such system will not be opened automatically rather it will remained closed as retaliation/reprisal against the foe. For a friend to enter the gate this system will make use of password challenging technique which would be already known within the organization securely. Further this manuscript will also address the practical/technical issues confronting in its manifestation.
Key Words- Intelligence, Security system, Scanner, Metal detector.
1. Introduction
The terrorism/violence globally is on increase with the passage of time. On micro level, a lot many measures/procedures are in practice to guard against this absurd fear. However on macro level, the arrangements of security to control this malignancy of blasts/suicide have failed to a superior extent and still their efforts are in progress. Many countries in cooperation/alliance with others have strived to stop the terrorism crusade. In vogue of such alarming scenario, a need has been felt to have a strong and versatile security system which could be able to reduce/minimize such deeds.
In the prevailing acts of violence/intimidation, many human lives have been lost and plenty of damage has occurred to the buildings and other nation infrastructure. In view of such drastic situations, an idea of creating a security system from mitigation of suicide attacks has been created which could guard against this violence at certain level. The main objective for the design of such system is to commence a new kind of system that can be used to scan a human body rather installing a huge and substantial scanning system at the entrance gate that is invisible even to a human eye. This security system is able to scan automatically while walking over. On contrary a person, in possession of any kind of metal / weapon or any radioactive material then automatically the gate with system installed will remained closed and will not be operated unless and until some authenticated /full proof procedure is adopted. This fabrication will definitely prove to be a useful/constructive instrument against these accessible aggressions for establishments/organizations like hospitals/health cares institutes, schools/colleges, universities, and other agencies buildings.
2. Working Scenario
This is apparently a unique and exclusive security system by which the events like suicide attacks etc can be controlled to a larger extent. The uniqueness of this system is the productive use of secretive operated metal sensors.
A person walks above this metal sensor system , following actions can be noticed to the best possible level:- a. A human body (in possession of metal/weapon or any radioactive material) walks over the metal sensor
actions/messages will be performed and controlled with help of digital computer based circuitry and, on detection; a message will be created on nearby emergency/rescue team centers due to GSM module.
b. On clearance of the concerned person by the system, all the gates successively will be opened and will keep on passing by. Such actions will completed through the Infrared (IR) Transmitter and Receiver installed at every gate coupled with the microcontroller functionality
c. The prime aspect of the use of such intelligent security system is that it is more secure in the facet when a person dealing with the administration affairs and is in possession of any metal/radio active material may be allowed to pass through the gate with the authenticated plan incorporating exceptional password challenging procedure. After inserting the password through keypad, this person will be able to pass through.
3. Assessment/Evolution through Flow Chart

rescue teams and concerned emergency forces with the help of GSM module which is also controlled by the main controller. After ward the IR sensors will allow the person to pass through gate #2. Once a person is between gate #2 and gate#3, the gate #2 will be closed by the controller and the same time the person in question will be trapped between gate2 and gate3. and will be unconscious by the activated spray system to prevent any damage/untoward incident. On the other hand, this system is friendly for authorized/authenticated person even bringing any metal material through reliable and secure challenging procedure.
6. Discussion /Major Components Overview 6.1 H Bridge Motor Driver
Fig 3 illustrates an electronic circuitry of H-bridge that enables a voltage that is to be applied in either direction across a load. These circuits are frequently worn in robotics and other applications which allows to run DC motor in flipside and onwards. These bridges are accessible as integrated circuits, and even from discrete components that bridges can be built. The "H-bridge" term is resultant from the graphical demonstration of this circuit. Moreover, by four switches H-bridge is constructed. When the switches S1 and S4 are bunged and S2 and S3 are opened, the voltage that would be applied across a circuit is positive voltage. Further more closing the S2 and S3 switches instead of S1 and S4, the voltage will be inverted, which applied repeal operation to a motor. Using the above taxonomy, the S1 and S2 switches should never be bunged at the equivalent moment, due to which an input voltage would cause a short circuit. The identical function applies to the S3 and S4 switches. This condition is known as shoot-through. The IC BA6418N is almost certainly a reversible-motor driver whose utmost output current is 0.7A. There are two logic inputs which allows four output modes: frontward, reverse, stop, and brake. Since there are separate ground pins on logic and power sections, the IC can drive speed-variable by connecting an electronic head circuit. The states of switches at various conditions are manifest from the Table1.

signal it will filter this signal and send this signal to the Q2.It will further filter the signal and send this signal to the LM741. The first LM741 IC is used as a receiver whose pin 2 works as a receiving principle. After receiving the signal, the LM741 will transmit this received signal to the second LM741. The second LM741 is used as an amplifier. This IC will amplify this signal and send this to the output of the circuit. The capacitor and resistors are used for matching with the circuitry of thecircuit.

6.3 IR Transmitter and Receiver
of photo detector proficient of converting light either into a current or voltage, depending upon the modes of maneuver. From the input a diode which is used for the protection of circuit. Further to regulates the +12V to the +5 volts an IC LM7805 is used. The 555 timer IC configuration is given in the data sheet of 555 timer IC. Pin 1 of the IC is grounded. The positive voltages to pin 4 is used to reset the 555 timer IC while pin 8 is used for the Vcc .Pin 2 is used for triggering the circuit. D1 acts as transmitter which receives the positive voltage direct ly from the supply and is also grounded. That’s why it will incessantly flashing the receiver, receiving the signal and trigger the 555 timer IC. After triggering the 555 timer IC output is taken from the pin 3. When the output is high the transistor will act as short circuit which makes the D3 grounded and this will give the output. Pin 5 is used to give the controlled output. Pin 6 and 7 are combined and are grounded with the 10μF to flash the led for a time. If the trigger is elevated then the output will also high and vise versa.
