CHAPTER ONE

INTRODUCTION

1.1    Background of the Study

Owing to the high rate of industrial espionage and theft, industrial security techniques need to be improved to arrest/combat pilfering in industries.  This project work tries to bring in an improved security measure which can be used to check pilfering in Brewery industries.  Pilfering of bottled drinks is a common theft in Breweries.  And this act is perpetrated in the conveyor before a standalone counting device takes account of it.  This has a tremendous effect on the stature of the fire – if it is not properly checked, could lead to liquidation and bankrupts of the firm.

Conventionally, there is a batch counting device that counts the bottled drinks and displays the values numerically at same spot carrier criminals who pilfer the products divert it before the counter.  This chronology in social vices in the brewery industry has motivated me to embark on a project that is capable of counting/the bottled drinks in the capable of counting/the bottled drinks in the conveyor and display the value numerical and wirelessly (using Rf transmission waveband) to its receiver installed about 100m away.  This device will count the product before it gets to the standalone version.  This technique will help to check pilfering and bring industrial espionage to halt.

1.2   Statement of the Problem

Brewery industries all over world face the problem of pilfering of the products by the workers most frequently in the conveyer. This menace gave way to the development of a stand alone batch counting device which is usually installed in the conveyors to record the total number of bottled products. This techniques is facing serious threat since the bad-eggs pilfer/divert the products before it gets to the counter. Owing to the challenges mentioned above, there is need to develop a system which will be installed at the entry point of the conveyors to count the products without the consent of the workers and display the value to a receivers unit  installed in the manager office using Radio-frequency technology.

1.3   Aims and Objectives

The aim of this project is to design and implement a Radio frequency based wireless batch counter capable of counting bottled drinks/products and display it at a remote location.

1. To develop system which can communicate using Radio frequency technology.

2. To develop an opto coupler module which can detect opaque objects like bottle using laser diode and visible light

3. To develop a 2-digit decimal counting unit which can count from 00-99.

4. To develop a system
