INDUSTRIAL APPLIANCES CONTROL USING TV REMOTE

ABSTRACT

           In this project we are going to develop an embedded system, which will control all the industrial devices with commands from a Remote device through IR.The IR light is invisible light about 950 nm wavelength. One biggest problem in using IR light is that there many other sources of it like sun, light bulbs, fire. In order to exclude other sources, IR signal is modulated by some frequency. Receiver has to be tuned for this frequency. Mostly remote controls transmit IR signal using 36 kHz frequency signals. Transmitting and coding is one part which can be done more easily than receiving and decoding.

DC MOTOR SPEED AND DIRECTION CONTROL USING IR

The main aim of this project is to control the speed and direction of DC motor using IR remote. For controlling the speed we are using PWM technique. A pulse width modulator (PWM) is a device that may be used as an efficient DC motor speed controller or light dimmer. This project is a versatile device that can control DC devices which draw up to a few amps of current.

A PWM circuit works by making a square wave with a variable on-to-off ratio, the average on time may be varied from 0 to 100 percent. In this manner, a variable amount of power is transferred to the load. The main advantage of a PWM circuit over a resistive power controller is the efficiency, at a 50% level, the PWM will use about 50% of full power, almost all of which is transferred to the load, a resistive controller at 50% load power would consume about 71% of full power, 50% of the power goes to the load and the other 21% is wasted heating the series resistor.

STEPPER MOTOR CONTROL USING IR

The project deals with the design and development of hardware and software for Wireless Stepper motor control system.

Rotating the motor anticlockwise or clockwise, or completely stop the motor can be done easily with an IR remote without actually going near the motor switches and operating them manually. The manual operation of the motor is completely avoided in this project.

IR remote acts as the transmitter in this project. When a button is pressed in the remote, the signal will be passed and received by the IR receiver TSOP Receiver.

ENERGY SAVER FOR AUTOMATIC ROOM LIGHT CONTROLLER WITH VISITOR COUNTER

      In this competitive world and busy schedule human cannot spare time to perform his daily activities manually. The most common thing that he forgets to do is switching OFF the lights wherever they are not required. This project is a standalone automatic room light with visitor counter. The main aim of the project is to control the lights in a room depending upon lighting that is present in the room and count the number of persons entering into the room. Use of embedded technology makes this closed loop feedback control system efficient and reliable.

 The system comprises of an IR Transmitter-Receiver pair which is located in front of the door outside the room.

AUDITORIUM CONTROLLING SYSTEM USING IR

In auditoriums, the lights and fans will be switched on before the show so that there will be no disturbance to the audience while the program is going on. But sometimes due to the weather conditions, we need to operate them in between the show. This may create inconvenience to the audience while the operators move here and there to operate the lights or fans. And even the wires associated to these lights and fans will be running on the floors and in the dark, the audience may feel inconvenience while walking out or coming inside the auditorium as they slip down. To avoid all these problems, we have designed a project that completely eliminates cable wires and the operators to operate the lights and fans in the auditorium.

 The main aim of this project is to automize the unmanned railway gate i.e. the gate is closed automatically whenever the train comes and is opened after the train leaves the railway-road crossing. Using this project, the arrival of the train can be identified in either direction. For this purpose, two IR transmitter and receiver pairs are used in this project.  LCD is provided to display the information about the arrival and departure of the train.

 The aim of this project is to atomize the car park for allowing the cars into the park. LCD is provided to display the information about the total number of cars that can be parked and the place free for parking. Two IR TX – RX pairs are used in this project to identify the entry or exit of the cars into/out of park. These two IR TX – RX pairs are arranged either side of the gate. The TX and RX are arranged face to face across the road so that the RX should get IR signal continuously.

TIME MEASUREMENT SYSTEM FOR ATHLETICS

The project Time Measurement System for Athletics calculates the time without actually using any mathematical calculations. This project uses the wireless concept IR. IR has the advantages of fast communication at shorter distances.

IR Transmitter and Receiver pair will be arranged at the destination point. Whenever the race starts, a stop watch will be started. The IR transmitter and receiver pair will be facing each other in such a way that the IR signal from the IR transmitter will be received continuously by the IR receiver. This output from the IR receiver will be given to the microcontroller.

REMOTE CONTROLLED DIGITAL CLOCK OR FARES DISPLAY USING IR

The main aim of this project is to display time or fares on the display board whenever the owner wishes to. This can be mostly seen in gold rates display in jeweller shops. The variations in the gold price can be seen daily. So the owner needs to change the previous value and update with the new value. Most of the gold shop owners do it by writing on the black board arranged in their shops. They can avoid this by sitting at their present place using wireless concept, IR.

Seven segment displays are used in this project as the display units. IR remote acts as the transmitter in this project. When a button is pressed in the remote, the signal will be passed and received by the IR receiver TSOP Receiver. This signal is sent to the microcontroller which decodes the signal and displays the corresponding number pressed in the remote.

IR BASED APPLIANCES CONTROL SYSTEM

         In industries or at homes, there will be various loads to be operated and these loads are to be operated at some specific intervals according to our requirements and also based on the device’s constraints. For these purposes, a person should be employed to monitor the status of the loads. But there may be chances that the person may forget to operate these loads. And also it is not an easy task for a person to operate these loads manually as these loads run with high currents and high power consumption. This project gives the best solution for electrical power wastage. Also the manual operation is completely eliminated. This project does this application using wireless concept.
