In industries various parameters such as i.e. temperature, light, speed,& in hazardous area parameters i.e. fire, humidity, smoke etc.

are difficult to measure & control.

Some areas are restricted because of security reason. i.e. like control room

or manufacturing area or high temperature zone of company.

Some areas are restricted because of safety reason i.e. Chemical gas plant.

To monitor & controlling on such field is difficult to task.



Cost effective.

Provide various applications as per client requirement.

Remote sensing for hazardous area.

Monitoring as well as controlling.

High speed communication .

Wireless technology.

Access high coverage area.

Multifunctional design.

Feature oriented .

Aim : To design a system which will separate industrial field or hazardous area

from a central location, using advanced wireless technology SCADA &

ZIGBEE.



Analog systems are wired.

Analog methods are very time consuming

Requires manpower to control.

It is wired so cost factor is very high. Critical to design & interface.

Consume more power.

High maintenance.

Bulky.



SCADA - Supervisory Control & Data AcquisitionDesigned to collect field information & transfer to central computer formonitor & control entire system in real time.

Zigbee - IEEE 802.15.4 standard

Advanced wireless technology standard established in 2004.

Two way communication.

Self organizing network.

General purpose.

Inexpensive.

Secure. Global implication.



Supervisory Control & Data Acquisition.

Combination of telemetry & data acquisition which interfaced via

PLCs or DCS(distributed control systems).

Supervisory Control of equipments installed on fields.

i.e. closing & tripping of switch gears, trap changing of transformers.

Data Acquisition of instruments installed on fields.

i.e. to get information temperature of room, speed of motors etc.

Designed to collect information to monitor & control entire system

from central location.

Technological Standard Created for Control and SensorNetworks.

Specification for a suit of high level communication protocol.

Based on the IEEE 802.15.4 Standard.

A Very low cost, low power consumption two-way wirelesscommunication standard for Automation.

Operates in Personal Area Networks (PAN’s) and device-to-

device networks.

Created by the ZigBee Alliance.



An industry consortium that promotes the IEEE 802.15.4 standard

Reliable and self healing

Supports large number of nodes

Very long battery life

Secure

Low cost

Can be used globally

Protocol stack: 32 Kb

Number of nodes: 264

Collision avoidance

Range: 1 - 40 km

Due to use of Zigbee range can be increased.

Not dependent totally on the AC mains supply.

Monitoring & Controlling.

Operate & access in real time.

Cost effective.

Wireless technology.

Easily compatible.

Less manpower.

Small size.

Microcontroller – 16F877A - High performance RISC CPU

Sensors - measure related parameters

Relay driver - switching purpose

Zigbee wireless technology - provide end to end connectivity

Zigbee transmitter - transmit data from field

Zigbee receiver - receive data from field

LCD - display measured parameters

MAX-232 - interface between µC & LCD

Software's - programming in C & VB



Monitoring & controlling of temperature for remote area

Monitoring & controlling of light for remote area

Find leakage of gas detection & generate alarm

Introdurer for restricted area

Humidity of remote area

As we increase sensors & our system hardware then no. of

innovative applications are also increased.



Accurate digital sensors gives the precision error can bedetected to generate an alarm at the user end.

The data can be transmitted to the mobile station. i.e. handsets

or satellites can be used to transmit data worldwide.

For higher data speed fiber optic cables can be used.

Remote range can be increased up to 40 km.

No. of applications can be increased as per client requirement.

In our project focus is to define a wireless technology

which is inexpensive, self- organizing, mesh network that can be

used for industrial control such as power switching & remote

sensing of hazardous area to monitoring smoke detection, gas

detection to secure mankind.
