OBJECTIVE

To measure and monitor the ingredients of batching

plant and analyze the strength of the product.


ABSTRACT

In this system, the scanner is given multiple inputs using

various communication modules like RS 232, Bluetooth and

RF. It selects each input for a fixed time period. This data is

stored in RAM and is delivered using various communication

modules like RS 485, GPRS and RS 232 to the host PC ,

mobile and to the printing device.


INTRODUCTION

WHAT IS A SCANNER? An electronic device which records data over time via

external instruments.

It accepts multiple inputs , and transmits them to PC , single data at a time.

BLUETOOTH

• Bluetooth Special Interest Group(SIG) founded by

Ericsson, Intel, IBM and Toshiba.

• Wireless technology defined by IEEE 802.15

• Low cost technology.

• Uses radio transmission in ISM band.

• Caters to short ranges.

HOW BLUETOOTH WORKS ?


Fig 1 Master Slave Communication

TECHNICAL SPECIFICATIONS OF BLUETOOTH

• Frequency of operation: 2.4 GHz, ISM band consisting of 79

channels each of 1MHz freq.

• Modulation: Gaussian Frequency Shift keying(GFSK).

• Operating Ranges:

• Maximum data rates ranges from 1Mbps to 3 Mbps.


Class Transmitted Power

Range

Class 1 100mW 100m

Class 2 10mW 50m

Class 3 1mW 10m

Table1: Operating Ranges

ADVANTAGES OF BLUETOOTH

• Economic wireless solution for short distance.

• Automatic.

• Low power and low energy consumption.

• Inexpensive technology.

• Low interference.



RS 232 Serial Communication

• A simple, universal, well understood data interface introduced by EIA.

• Max 256 kbps, line length 15 M (50 ft) or less

• Signal representation (bipolar: +3 to +15v, -3v to –15v)

• Full duplex communication.

COMMUNICATION PARAMETERS OF RS232

• Different Data rates.

• Data bits: 5 to 8 bits.

• Start bit and Stop bit used.

• Parity used.


DISADVANTAGES OF RS232

• Increases power consumption .

• Complicates power supply design.

• Unbalanced transmission.

• 25-way connector too large.


RADIO FREQUENCY (RF)

• Rate of oscillation (30 kHz to 300 GHz).

• Electrical and not mechanical oscillations.

• Covers significant portion of electromagnetic

radiation spectrum,9 KHz..


GENERAL PACKET RADIO SERVICE

(GPRS)• New bearer service for GSM .

• Improves and simplifies wireless access to packet

data networks.

• Applies packet radio principal to transfer user data

packets between MS & external packet data network.


FEATURES OF GPRS

• Provides Data Packet delivery service.

• Support for leading internet communication

protocols.

• Billing based on volume of data transferred .

• Utilizes existing GSM authentication and privacy

procedures.


BENEFITS OF GPRS


•High Speed (Data Rate 14.4 – 115 kbps).

• Efficient use of radio bandwidth .

• Circuit & Packet Switching used in parallel.

• Constant connectivity.

RS-485

• Provides balanced transmission line .

• Allows high data rates communications.

• Max speed of 1000 kbits/s and max distance up to

4000 feet.

• Provides 32 drivers and 32 receivers.


ADVANTAGES & DISADVATAGES OF RS485

ADVANTAGES

• Lower signal level interface.

• Max data transmission speed .

• Good noise immunity.

• Multi-station capability.


DISADVANTAGES

• Special communication cable needed.

• Only one node can transmit data at a time.
