ABSTRACT

There is considerable interest in wireless communication of data in industrial processes. Wireless

sensors, in particular, have the potential to cut up to 90% of the installation costs from many industrial

sensor wiring installations. Reduced cost in wiring installation and wiring maintenance, along with

increased data gathering flexibility are the benefits of wireless sensors. The substantial reductions in

installed cost allow new monitoring and even control capabilities. This paper gives practical approach

about how wireless communication robust enough for industrial plant environment.

KEYWORDS: WSN (wireless sensor network), industrial automat ion, smart ho me, remote

control.

I. INTRODUCTION

Remote control switching application are coming into existence in da y to da y

applicat ion definitely in ho mely applicat ion in industrial applicat io n and many more,

moreover they are very much applicable industrial applicat io n such as remote control light

management dc motor speed management and many more. In nearly eve ry factory floor

and industrial setting, co mmunicat io n links carry vit al informat ion between machinery,

control, and mo nitoring devices. Fro m periodic updates to ongoing process and

manufacturing management, reliable data flow is crit ical to operations. Mu ch o f the

control and status informat ion transferred in industrial setting actuator posit ion,

relat ively litt le bandwidth and connect ion speed a t the other extreme, large file

transmissio n, such as act ivit y logs fro m a production run, re quires mo ving a lot of data

very efficient ly [10].

We must understand the techno logy of wireless co mmunicat ion which is, after all

simply a redio co mmunicat io n link. Radio waves are a fundamental electromagnetic

property o f matter. This property is manifested when an electric current passes through a

metal conductor displacing electrons fro m their orbit s and giving o ff energy. The amo unt

of energy emitted is proportional to the amount of passing current. By passing an

alternat ing current through the conductor, a sinuso idal electromagnet ic wave is

transmitted into space.

Now by considering all o f t hese applicat ions it is possible to develop a new remote

control s ystem, which will be very much helpful in many ho mely applicat ions as per

controlling switchboard by remote, such as to control tube light, fan etc in any house. This

remote control is also useful in agriculture applicat ion as well as in industrial applicat i on.

I. BASIC CONCEPT

AVAILABLE REMOTE CONTROL SYSTEM: In t he available remote control syst em

there are many t ypes o f disadvantages as per they are mak ing use o f IF co mmunicat ion to

control the ho me appliance just to make it on and o ff, the proble m is that it is strict ly said

to use the remote in t he room it self where we want to control the device. Interference

between the IR transmitter and the IR receiver will create the problem o f loss o f signa l

which ma y create problem o f false swit ching.

MODIFICATION IN PRESENT SYSTEM: The new designed system is more flexible and easily controlled by any user the system do have more advance part than IR remote

control as per this modified remote control is making use o f Radio Frequency to control

the appliances. Due to RF signal the syst em will avo id the problem o f false interference

between the remote and the device so as toavo id false interference. The main advantage of

using this system is t hat we can control any appliance in any room fro m any other room

fro m diameter of 100m.

II. DESIGNED NEW REMOTE CONTROL SYSTEM

It is completely related with controlling of appliances using remote by which we can control the

appliance from a respective distance of 100m.

A. REMOTE SECTION: It consists of different blocks to represent the total section of the transmitter

or the remote control.

FIG 3: Remote Section

 SWITCHING SECTION: The initial section where the switch is connected to switch ON the

proper appliance to make it on and off. Micro switches are used to make the device on or off.

Switching section is connected with the parallel to serial converter section to convert the pressed

switch into proper data and to convert the parallel data into serial data so as to transmit it using

digital transmission technique FSK.

 PARALLEL TO SERIAL CONVERTER: Output from the switching section is given to the

parallel to serial converter where pressed switch is recognized and a proper data is made with

respect to the pressed switch this data from the switch is taken in parallel from and converts form

and the parallel data into serial form to transmit the data.

 FSK MODULATOR: Data from the parallel to serial section given to the FSK section to

modulate the signal with respective frequencies. Two different frequencies are used for keying

with respect to the data.

F1: This is the section where the first frequency is generated.

F2: This is the section where the second frequency is generated.

These two frequencies are connected with the FSK modulator section to take respective actions

with respect to data coming serially.

 ANTENNA: The modulated signal is taken and is transmitted by converting electrical signal into

electromagnetic waves.

B. RECEIVER SECTION: Signal transmitted from the FSK transmitter is received and decoded

properly to receive the original transmitted signal. Receiver section for all the application is same but

the application changes internally by proper software manipulation.

ANTENNA

FIG 4: Receiver Section

 ANTENNA: This section receives the signal from transmitter. It converts electromagnetic waves

into electrical signal which is in the form of frequency and is given to the next section to convert

it into its respective format.

 DEMODULATOR: Demodulates the transmitted signal from FSK modulator and generates the

respective data coded from the transmitter. The data is presented in the same 4 bit form as

transmitted from transmitter.

 SERIAL TO PARALLEL CONVERTER: Signal from the demodulator section is filtered and

is given to the parallel to serial converter section where the serial data is converted into parallel

for to generate the original signal or the status of the switch which was pressed from the

transmitter.

 PORT: The port is totally related with the microcontroller where port P1 is used as the input

port where the data from the receiver’s serial to parallel section is given to the port in 4 bit form.

III. APPLIANCE CONTROLLING USING REMOTE

Appliances are controlled by making ON and OFF as per user need, just by controlling the device using

remote.

RECEIVER SECTION: This section receives the data transmitted from the FSK transmitter or

generates the respective data from the switch pressed by the user. The data in the 4 bit form that is given

as input data to the input port of the microcontroller and the microcontroller will behave depending on

the program.

MICROCONTROLLER SECTION: This section manipulates the complete operation by making the device ON and OFF or to control the device or to multiplex the application. The total function depends

on the programming stored in the microcontroller and depending on the program, it manipulates the total

function. This microcontroller has 4 ports which can be used as input as well as output port which

depends on the application used in the project. This same microcontroller is used to manipulate all the 3

applications, which is manipulated one by one.

 Appliance controlling using remote

 Home light management system

 Fan speed management system

BUFFER SECTION: This is a latch section, which is helping the microcontroller to multiplex the

application one of the port of the microcontroller, controls the buffer to allot the proper application. The

buffer is executing 4 bit data operation.

BISTABLE SECTION: It holds the single bit data, but the data set or reset state depends on the clock

for the first clock it sets and for the second clock it resets and vice versa the clock of bistable section is

connected with the buffer, for 4 bit 4 bistable section is made. The output of the bistable section is given

to a transistor to drive a relay to control the heavy appliances.

MICROCONTROLLER SECTION I N P O R

OPERATION: Here as per the block diagram, the receiver section receives the signal from the transmitter and decodes it by converting it into proper digital data then the data is convert into parallel

form as per the original data transmitted from the FSK transmitter or the switch pressed. The data input

port is port 1 and the data output port is port 2 where the data is given out to control the devices.

A buffer IC is connected to control the multiplexed function of the controller to attend no of

applications. Port 3 is used to control the buffer to handle the other applications from the remote, if the

switch is pressed and released a pulse is transmitted and is received by the receiver section where the

same data is presented as the input port of the microcontroller. This same pulse presented at the output

and is given to bistable multivibrater to fix the on or off function of the device. A relay used to make the

device on or off as per the use of the user.

CONCLUSION

This remote control system is a complete solution for all of the remote control operated application that

may be in home, industry, defense or any other because this system is designed full proof to sustain in
