EMS 2001. REMOTE ACCESS CONTROL AND AUTOMATION SYSTEM FOR ELECTRONIC APPLIANCES USING TELEPHONE LINE

The aim of the project is to access home appliances even though we are outside our home. Here in this project, we use telephone line as control media. The project allows us to control home appliances such as Fan, TV, Motor, and Lamps etc. All we have to do is to connect the gadget to our telephone lines and the output lines of gadget to the respective ac loads to be controlled to access the appliance. The user should dial his phone number followed by a respective device number. The data is thus transferred to our house via telephone lines. Our gadget automatically detects the incoming phone call and establishes a connection. Then it notices the pressed device number and turns on/off the gadget and also gives a beep alert to the caller while a device is turned which helps the caller to know the status of the device. Thus the project is much useful when we move outstations thus allowing the worldwide access via telephone line. The gadget automatically disconnects from the telephone line within 0 seconds from the time of establishment of connection. To prevent the misuse, a password security may be added to prevent the usage of gadget from intruders, which can also be stated as a future enhancement

The actual sensor is sensible to metals and chemicals used in bomb). The ROBOT consists of IR receiver and microcontroller unit, which drive the wheels of the ROBOT via pairs of DC motors. The receiver pairs placed at the front of the ROBOT resemble that of a car headlight. The ROBOT revolves round for a valid IR signal from the bomb. If it picks the IR rays it moves towards it and warns a loud siren about the presence of bomb. It also gives a voice alert about the presence of the bomb.

The ROBOT consists of two pairs of IR trans-receivers placed at bottom. The microcontroller in the ROBOT scans for the reflected light. If the ROBOT is in black line position no light rays is reflected. Else, if it moves away from the black line, one of the sensor reports the microcontroller availability of reflected light. The microcontroller correspondingly controls one of the motors, which is coupled to the wheel of ROBOT and changes the direction of ROBOT towards the line.

EMS 2019. IMPLEMENTATION OF WIRELESS AUTOMATION AND CONTROL THROUGH RADIO FREQUENCY TECHNOLOGY

The term wireless communication refers to transfer of information via electromagnetic or acoustic waves over atmospheric space rather than along a cable. The apparent wrinkle between such a scheme and conventional wired systems is the presence of the wireless channel as the medium over which the communication must take place. Thus when considering a general digital wireless communication system design of each building block will be dependent on the channel between transmitter and receiver. This is invoked by RF Microcontroller based transmitter and receiver. By this we can control operation that is a relay connected to the receiver end.

EMS 2027. IMPLEMENTATION OF RFID SYSTEM USED FOR TRACKING AND AUTHENTICATION PURPOSES APPLYING BACK SCATTERING TECHNOLOGY

Radio Frequency Identification (RFID) systems use radio frequency to identify, locate and track people, assets, and animals. Passive RFID systems are composed of three components – a reader (interrogator), passive tag and host computer. The tag is composed of an antenna coil and a silicon chip that includes basic modulation circuitry and non-volatile memory. The tag is energized by a time-varying electromagnetic radio frequency (RF) wave that is transmitted by the reader. This RF signal is called a carrier signal. When the RF field passes through an antenna coil, there is an AC voltage generated across the coil. This voltage is rectified to result in a DC voltage for the device operation. The device becomes functional when the DC voltage reaches a certain level. The information stored in the device is transmitted back to the reader. This is called backscattering. By detecting the backscattering signal, the information stored in the device can be fully identified.

Because of its simplicity, the passive RFID system has been used for many years in various RF remote sensing applications. In recent years, there have been dramatic increases in application demands. In most cases, each application uses a unique packaging form factor, communication protocol, frequency, etc.

The circuit features automatic exit and entry delays, timed bell cut-off and system reset. It has provision for normally open and normally closed switches and will suit the usual input devices (Pressure Mats, Magnetic Reed contacts, Foil Tape, PIRs and Inertia Sensors). When the power is applied, if there's a fault the buzzer will sound and you should switch off again and check for open doors, windows, etc. If everything is in order the buzzer will NOT sound and the exit delay will begin. You have about 30 seconds to leave the building. When you return the buzzer will sound. You then have about 30 seconds to switch off; otherwise the siren will sound. It will go on sounding indefinitely. However, if the building is re-secured the siren will switch off after about 10 minutes and the alarm will reset. This is a complete alarm system with 5 independent zones suitable for a small office or home environment. It uses just 3 CMOS IC's and features a timed entry / exit zone, 4 immediate zones

These can be micro switches or standard alarm contacts (usually reed switches). Suitable switches can be bought from alarm shops and concealed in doorframes, or window ledges.

Once set any contact that opens will trigger the alarm, including Zone 1. To prevent triggering the alarm on entry to the building, the concealed re-entry switch must be operated. This will discharge C6 and start the entry timer. The re-entry switch could be a concealed reed switch, located anywhere in a doorframe, but invisible to the eye. The panic switch, when pressed, will trigger the alarm when set.  Relay contacts RLA1 provide the latch, RLA2 operate the siren or buzzer.

In this model we provide necessary tower, which resembles similar to a cell phone networking while the vehicle lies inside the coverage of particular tower, the tower name is displayed in an LCD display, which is actually placed in the control station that is few meters away. The TRANSMIITER that is placed with the person emits modulated RF rays, the RF receivers placed in the tower picks the RF rays emitted while the vehicle is inside the coverage range of that particular tower and the each tower is assigned with unique DTMF CODES while IR rays are picked by the tower it in turn generates a DTMF signal which is transmitted to the control station by a low power FM transmitter the FM receiver placed at the control station picks the FM signal and demodulates and retrieves back the DTMF signal. The DTMF decoder placed after the receiver section converts the DTMF tones into binary codes, the binary data is fed to the micro controller AT89c51 in turn drives a LCD display, which displays the area information.
