ABSTRACT

Our paper provides the security in Indian military. Two sections are provided in the circuit.

  1. near the border which is totally controlled automated with GSM.
  2. Security station which can be operated manually.

A special type of object sensor is ultrasonic used to detect the object around 2 feet distance. This sensor uses the concept of object motion and distance. If anyone tries to cross the border means the sensor detects and it sends a signal to the microcontroller switch on the camera which captures the image of the object and it display the image to the near security station. In the receiver circuit is used which receives the signal from the border and displays the image captured on the computer monitor. After sensing the image, the official can take the action in the border side the micro controller activates the motor driver which drives the load such as automatic movement of camera, alarm. This circuit sends a massage to officer of security station by GSM module.

INTRODUCTION

In the project “Country Border Security system” we have shown the concept of an automatic border security. As in the modern world everything is going automatic we have built a system which will automatically sense motion and the entry of an unwanted person in the country. We have deployed a microcontroller which is used to sense the signals from all the sensors which are placed in the country border for sensing different type of failures or security conditions. It is also possible to send a message and video capture when there is any unwanted situation in the country border sensed by security system , apart from this an audio visual alarm is also planted in the control room which will get activated at that time. This security system takes to target of unwanted person and suited it through gun.

There are two sets of sensors: one of which sense any type of movement and distance of any unwanted person in the absence of country border, second camera for capture to image of object. When any unwanted person in the absence of country border is sensed by the ultrasonic movement detector it will get activated an give a low signal to microcontroller’s pin , and this pin when sensed by the microcontroller then it will activate the audio visual alarm, apart from this a sms is also sent to the control room and capture image in computer. Similarly when any person enters in the country through the border then an intruder ckt.(which act as a sensor for sensing the entry or exit of an unwanted person) will get activated and give a low signal to microcontroller which is sensed by the controller . Then controller in turn activates the audio visual alarm and also sends a sms to the control room.

RANG FINDER

This project, an ultrasonic rangefinder from 1979, shows how to make a distance finding device using ultrasonic sound waves.

This includes only the block diagrams and no circuit but detailed description shows what is going on.

The interesting part of this design is not so much the range finder itself (since using microcontrollers you can build one more easily), rather it is using a simple RC circuit to differentiate a monostable pulse output (a square pulse).  And then using a comparator to trigger activation of the receiver.

Not only this but the received ultrasonic signal is used as input to the other side of the comparator as a reference i.e. to trigger the measurement action.  The key point is that the differentiated pulse lowers the threshold for the comparator trigger meaning that the circuit should respond better to lower signal levels i.e. reflected ultrasonic sounds received from a greater distance.

There is a free project on this site for a microcontroller based ultrasonic range finder with circuit diagrams – it would be interesting to add in the variable threshold and see if it can be improved!  it should do so as the level detected will be improved the further the distance that the ultrasonic sound wave is reflected.

For changes in that circuit (in the above link): You can see the threshold comparator U6 and threshold adjust VR2.  You would need to use a spare output from the 16F88 say one of the spare signals on port RB, to generate a pulse and then add the CR network to differentiate that and feed into the comparator (pin 3).

Executive Summary of the Ultrasonic Rangefinder

An ultrasonic rangefinder providing a correct distance measurement and comprising a first transducer for transducing electric signals into ultrasonic waves and transmitting the ultrasonic waves, a second transducer for receiving the ultrasonic waves and transducing the ultrasonic waves into electric signals, a differentiation circuit, and a comparator for comparing a level of a differentiated output signal from the differentiation circuit with an output signal level of the second transducer and detecting a threshold time when the level of the differentiated output signal from the differentiation circuit becomes lower then the output signal level of the second transducer where a threshold signal level of the comparator is automatically varied with respect to a time lapse of the traveling ultrasonic waves coming back to the rangefinder after being reflected by an object, thus overcoming the conventional problems due to the spurious-like direct waves.

VHDL Project’s List
with Rating
  • 1    DESIGN AND IMPLEMENTAION OF BIST(BUILT IN SELF TEST) FOR RAM       (GOOD)
  •       BIST is the capability of testing chip by itself. The key idea of BIST is to place a test pattern generator and a test data
  •       evaluator. BIST has many advantages over the traditional testing method. the program has been carried out for testing
  •       RAM and VHDL codes written for each block.
2   STEPPER MOTOR DRIVER                             (SMALL)
     A microprocessor lab needs a universal interface to drive a stepper motor. in order to experiment with microcontroller driving
    stepper motor it would be useful to have a single universal interface IC wired to stepper motor. This circuit needs to accept any
     of the typical forms of stepper motor drive signals from microcontroller and activate the windings of the motor to make it move
      in desired manner
3   KEYPAD ENCODER                (SMALL)
     A Digital circuit that encodes a hexadecimal keypad into a four bit binary output.
4   DIGITAL CLOCK    (GOOD)
     A time clock that displays the time of day in hours, minutes, and in seconds.
5  VITERBI  DECODER            (VERY GOOD—BIG)
    The Viterbi decoding algorithm proposed in 1967 is a decoding process for convolutional codes. Convolutional coding has
    been used in communication systems including deep space communications and wireless communications. Convolutional
    codes offer an alternative to block codes for transmission over a noisy channel. Convolutional coding can be applied to a
    continuous input stream (which cannot be done with block codes), as well as blocks of  Data
6   Wallace Tree Multiplier           (GOOD)
     Wallace Tree Multiplie is considerably faster than a simple array multiplier because its height is logarithmic in word size, not
     linear. However, in addition to the large number of adders required, the Wallace tree’s wiring is much less regular and more
     complicated. As a result, Wallace trees are often avoided by designers, while design complexity is a concern to them.
7   DIFFERENT TYPE OF MULTIPLIER
8  LANDLINE SWITCHING SYSTEMS  [ONE WAY    (SMALL)     OR    MULTIWAY        (VERY GOOD)]
     This project was designed to develop a VHDL code which would perform three basic functions of an electronic switching
     system to transmit signals over the connection or over separate channels to convey the identity of called and the calling
     address,and alert the called station; to establish connections through a switching network for conversational use during the
    entire call; and to process the signal information to control and supervise the establishment and disconnection of the
    connection We considered a group of eight subscribers between whom we had to establish the connection. We used the
     behavioral modeling of VHDL to implement the switching system. We used array structures for control, data and caller id
    memories while SS7 protocol was used for signal transmission through the switching network,Thus both the single way and
    multi way landline switching systems were successfully implemented through VHDL. Hence the project enabled us to design
    ICs for a landline switching system.
9  HAMMING CODE FOR ERROR DETECTION AND CORRECTION   (GOOD)
Richard Hamming found a beautiful binary code that will correct any single error and will detect any double error (two separate
errors). The Hamming code has been used for computer RAM, and is a good choice for randomly occurring errors. (If errors
come in bursts, there are other good codes.)
10   4 BIT OR 16 BIT MICROPROCESSOR  (GOOD)
11   TRAFFIC LIGHT CONTROLLER (SMALL)
       Traffic light controller, we can be used to control the function of traffic-light signal on the main road.In this controller, we have
      three mode –
     1. > Regular:- States each with an independent programmable time passed to the circuit by means of constant.
     2. > Test :- In Test mode all preprogrammed timers to be overwritten with a small value such that the system can be easily
            tested during maintenance. This value should be programmable and passed to the circuit using a constant.
     3. > Stand by :- If set the system should activate the yellow light in both direction and others remain off so while the stand by
            signal is active.
