SMS Based Industrial Automation Using ARM Controller
Introduction
 Automation plays an increasingly important role in the global economy and in daily experience.
 In this day and age of computers, industrial automation is becoming increasingly important in the manufacturing process because computerized or robotic machines are capable of handling repetitive tasks quickly and efficiently.
OVERVIEW
 ARM processor
 GSM Architecture
 AT commands
 Transactions between GSM and ARM
 Advantage , Disadvantage and Application
 Conclusion
PROBLEM OCCURS BEFORE GOING TO THIS PROJECT
 Availability Critical to Function
 Fail-Safe Hardware
 Non-Delayed Response
BLOCK DIAGRAM
Why we used ARM controller?
 32 Bit Microcontroller
 RISC
 Pipelining
 Von Neumann Architecture (Physical Memory up to 4GB)
 Clock Frequency up to 50MHz
 It has Two Instructions Set
 Standard 32 Bit ARM Instructions Set
 16 Bit THUMB Instruction Set
LPC2129 SPECIFICATION
 16/32-bit ARM7TDMI-S and 64 pin package.
 16 kB on-chip Static RAM.
 128/256 kB on-chip Flash Program Memory.
 128-bit wide interface for high speed operation.
 Multiple serial interfaces: Two UARTs (16C550),
and Two SPIs
 Temperature range is -40degree to +85 degree
GSM ARCHITECTURE
 Network switching subsystem
 Base station subsystem
 Network management subsystem
AT COMMANDS
The "AT" or "at" prefix must be set at the beginning of each command line. When we enter AT and send that command to GSM modem it will give an acknowledgment by sending OK command
Components used
Transmitter section
 GSM based Mobile Station
Receiver section
 GSM modem
 ARM controller
 Relays
 Stepper motor
 LCD displays

Pin descriptions
GENERAL PURPOSE INPUT OUTPUT (GPIO)
 Direction control of individual bits
 Separate control of output set and clear
 All I/O default to inputs after reset
 PORT0 and PORT1 are controlled by two groups of 4 registers such that IOPIN,IODIR,IOSET,IOSET

ADVANTAGE & DISADVANTAGE
Advantages:
 Safety of Control Personnel
 Access by Multiple Users
 User Friendly GUI
 Fast effective & flawless service
 High reliable and flexibility
 Reducing cost
Disadvantages:
 If network is busy the delivery of SMS may fail
 More number of relay ports there will be always a delay in the response time of the system
APPLICATIONS
 • Industrial control
 • Medical systems
 • Access control
 • Point-of-sale
 • Communication gateway
 • Embedded soft modem
 • general purpose applications
CONCLUSION
There are many alternatives for controlling devices individually but the proposed system is a multiple device control which really saves the time, energy and cost of the human being more reliable and effective.
Future Scope:
Feedback can be employed to the transmitter
We can prevent the using of unauthorization person
Wireless router and hub can be used to enable the connectivity of the Hardware
