INTRODUCTION:

Programmable logic controllers are modular, industrially hardened computers which

perform control functions through modular input and output (I/O) modules. The modularity of

PLC allows the user to combine generic I/O modules with a suitable controller to form a control

system specific to his is most simply understood needs. The operation of a controller by

envisioning that it repeatedly performs three steps:

1. Reads inputs from input modules

2. Solves preprogrammed control logic

3.Generates outputs to output modules based on the control logic solutions. Input devices

and output devices of the process are connected to the PLC and the control program is

entered into the PLC memory.

In our application, We monitoring and control the motor speed and also to

detect the unwanted presence offire by monitoring environmental changes associated

with combustion.

OBJECTIVE:

1. To Monitor the Motor Speed and take necessary control action very fastly

using PLC.

2. To detect the abnormal temperature caused by fire or any other causes

using PLC.

SCOPE OF THIS PROJECT:

This application project is very much useful in all industries to maintain their linear

production, save their Machinery things and human lives.

BRIEF METHODOLOGY:

The implementation of a monitoring and control system for the motor based on

programmable logic controller (PLC) technology is described. Also, the implementation of the

hardware and software for speed control and protection with the results obtained from tests on

motor performance is provided. The PLC correlates the operational parameters to the speed

requested by the user and monitors the system during normal operation and under trip conditions.

Tests of the motor system driven controlled by PLC prove a higher accuracy in speed regulation

as compared to a existing system. Thus, PLC proves themselves as a very versatile and effective

tool in industrial control of electric drives.

An automatic fire alarm system is designed to detect the unwanted presence

offire by monitoring environmental changes associated with combustion. In general, a fire alarm

system is classified as either automatically actuated, manually actuated, or both. Automatic fire

alarm systems are intended to notify the building occupants to evacuate in the event of a fire or

other emergency, report the event to an off-premises location in order to summon emergency

services, and to prepare the structure and associated systems to control the spread of fire and

smoke.

EXPECTED OUTCOME:

* PLCs are well adapted to a range ofautomation tasks. These are typically industrial

processes in manufacturing where the cost of developing and maintaining the automation system

is high relative to the total cost of the automation, and where changes to the system would be

expected during its operational life.

The output to be manually checked using hardware kits and also to be analyzed using

PLC Softwares.
