RADIO FREQUENCY BASED WIRELESS BATCH COUNTING DEVICE FOR BREWERY

Thesis Abstract

This project work deals on the design and implementation of a Rf based wireless batch counting device for brewery capable of counting the bottled products in the conveyor and displaying the value numerically and wirelessly to its receiver installed about 100 meters away.  This project is realized in two functional units the transmitter and receiver units.  The transmitter unit is installed in the conveyor while the receiver unit is installed at a remote location. They interact by the principle of electrical resonance using Radio frequency transmission waveband.  An Opto-coupler realized with Light dependent Resistor (LDR) and Laser diode form the sensor/electronic eye that detects the presence of bottle.  The output signal of the sensor unit is processed and used to cause the Tuned Radio Frequency (TRF) transmitter module to radiate an Rf signal to its receiver, some meters away.  On receiving the radiated signal, its output is processed and used to clock a 2-digit decimal counting unit that displays the number of counted bottles numerically.  This system implies a lot in computer, and EEE.  As a surveillance system, if the recorded value is not equal to the single unit version also installed in the front end of the conveyor, the workers involved will be fired. This system can only communicate to the receiver over a range of 100m maximum.  At the end of every production cycle, if the recorded value on the stand alone type is less than the value recorded by this system, the workers get queried.  The result being a system which can count the number of bottled drinks and relay the number/value wirelessly to a receiver some meters away.  It is not microprogram control rather pure random logic.
