CHAPTER 1: INTRODUCTION AND BACKGROUND

1.1 INTRODUCTION

Traditionally, in sericulture the weighing process is mechanical and selection

of cocoon is manually done. This takes a lot of time an inaccurate reading is

obtained due to human and mechanical errors. The farmer collects the

cocoons and sell them in the market where government bodies and private

bodies buy and sell the cocoon at various rates.

In the conventional methods of silk process, segregation of cocoons is done

with the help of a bulb along with natural light. After segregation, the cocoons

are put inside the steam bath, which requires 10-12kgs of bamboo for 6-8

mins of steam bath(for 200-300 kgs of cocoons).Further cocoons are boiled at

controlled temperature with manual stirrer. The manual stirrer does not spread

the temperature equally inside the bucket, which spoils the silk. and also for

the boiling purpose it needs a fuel of 750 kgs.

Here we propose to automate the market place and change most of the

mechanical process into electrical which would be more accurate and reliable.

The temperature is maintained at a constant celsius with the help of LM35



temperature sensor due to which the silk quality and the killing of the larvae is

not tampered.

1.2 OBJECTIVE OF OUR PROJECT

The objective of our project is to provide an aid for sericulture marketing.

Mass cocoon segregation mechanism by using electronic weighing machine.

To learn the concept of use of microcontroller.

Continuous monitoring of the temperature.

To get the weight difference before and after removing black spotted cocoons from the sample.

To maintain a log ,of the type and quality of the cocoons being supplied by a particular vendor and also the amount and quantity being settled for what price using pc with centralized database.

Optimize the entire system to make it accurate, efficient, cost effective.



1.3 ADVANTAGES

Semi automated cocoons selection

Less energy consumption and fast cocoon selection procedure

We propose to automate the procedure by connecting electronic

weighting machine to the microcontroller.

With modern GSM technique we will directly communicate with

farmer through SMS.

Less time consuming as we are using GSM technology.

2.3 WORKING DESCRIPTION

Following components are included in our Project

1. LOAD CELL :

We use CZL601 model load cell, which is a bonded metallic

type strain gauge , which uses full wheatstone bridge. The

output will be in terms of milli volts.

Therefore ,we use AD620 amplifier for amplification, the

gain of the amplifier will be 500.Design part is explained in

the next chapter.

2. TEMPERATURE SENSOR :

We use LM35 temperature sensor, which does the direct

measurement of temperature.

It gives 10mV/degree rise in temperature.



We give temperature sensor output directly to ADC, for

100ºC it gives 1V.

3. ADC :

The ADC0809, data acquisition component is a monolithic

CMOS device with an 8-bit analog-to-digital converter, 8-

channel multiplexer and microprocessor compatible control

logic.

The outputs from temperature sensor and load cell are

selected through IN0 and IN1 channel of ADC respectively.

Each input of ADC are selected once at a time by grounding

other input.

Based on the selected line of the ADC the output will be sent to the microcontroller.

4. RELAY MECHANISM :

We use relays along with ULN2003 driver circuit which is a

current booster for controlling the following:

Motor of the conveyor

Motor of the stirrer

ON-OFF control of tube light



5. MICROCONTROLLER :

Microcontroller interfaces with relay driver circuit and the

analog to digital converter. The output data obtained is then

sent to the centralized database through Max232.

6. CENTRALIZED DATA BASE :

In the PC using the centralized database we maintain a log of

the type and the quality of the cocoons being supplied by a

particular vendor and also the amount and quantity being

settled and for what price. These details can be used for

deciding and planning later. Visual Basic Language is used to

create the centralized database system.

7. GSM MODEM :

We use SIM300_V7.03 model of GSM modem

Through which the communication between Centralized data

base and the modem is made. Vice versa is also possible.



CHAPTER 3: HARDWARE COMPONENTS

HARDWARECOMPONENTSUSED FOR COCOON SELECTION

MECHANISM:

3.1 LOAD CELL

Load cell is a transducer, which converts pressure/weight into electrical signal. Inside the load cell the strain gauges are connected in a full bridge fashion. The load cell is used to measure the weight of the unknown cocoons in kgs. Normally the load cell can weigh upto 50 kgs or more than that.

RATE LOAD (kg) : 3～120kg

FIGURE 3.1.2: INTERFACING OF LOADCELL WITH AD620

DESIGN OF LOAD CELL:

Excitation voltage of load cell =5 v

Rated output of load cell = 2mV/V

For 120kg = [2mV*5] = 10mV

So, fullscale load of 120 kg →10mV output

Gain = [5/10mV] =500.

DESIGN OF AD620 AMPLIFIER:

The gain equation is

Rg = [49.4KΩ]/[499]=100Ω



Gain = [49.4kΩ/100]+1=495

3.2 ALGORITHM TO INTERFACE LOADCELL WITH ADC

STEP 1: Select the channel_0 of ADC to which output of load cell is connected.

STEP 3: Digital output of load cell is sent to the centralised database (PC) using serial communication.

STEP 4: Initial weight of the load cell is send to centralised data base by the controller, by sending equivalent character (!) value of data base

STEP 5: Second weight of the load cell is send to centralised data base by the controller, by sending equivalent character (@) value of data base

STEP 6: Original weight is calculated in centralised data base through VB software which is given by the following formula:

txtactualwt = txtoriginalwt - txtnewwt

3.3 TEMPERATURE SENSOR

DESIGN:

Temperature sensor range is from 1ºC to +150ºC

1ºC gives 10mV output

100ºC - 1V

150ºC gives 1.5V

In our application we need 100ºC to kill larvae.



DESIGN DESCRIPTION

LM 35 senses the temperature and converts it into voltage (Linear 10mV raise per

degree raise in temperature). The output of the lm35 is directly given to the

channel IN1 of ADC so that the analog output is converted into digital form for the

microcontroller.

FIGURE 3.3.1 LM 35

3.4 ALGORITHMTO INTERFACELM35 WITH ADC

STEP 1: Select channel_1 of ADC for initial temperature.


ADC


STEP 2: The temperature sensor input is given to ADC in terms of volts and digital output of ADC is given to microcontroller and then the controller communicates with PC through serial port.

STEP 3: In centralised database the temperature value ‘#’ describes the room temperature obtained from microcontroller.

3.5 ANALOG TO DIGITAL CONVERTER

The ADC0808, data acquisition component is a monolithic CMOS

device with an 8-bit analog-to-digital converter, 8-channel multiplexer

and microprocessor compatible control logic. The 8-bit A/D converter

uses successive approximation as the conversion technique. The

converter features a high impedance chopper stabilized comparator, a

256R voltage divider with analog switch tree and a successive

approximation register. The 8-channel multiplexer can directly access

any of 8-single-ended analog signals. The device eliminates the need for

external zero and full-scale adjustments. Easy interfacing to

microprocessors is provided by the latched and decoded multiplexer

address input.

INPUT:

Temperature sensor (1V) O/P is connected to pin IN1 and amplified load cell (3V) O/P is connected to pin IN0.

The output data obtained is then sent to the centralized database through Max232.The Port0 i.e. P0.1-P0.7 are connected to the ADC. P2.1,P2.2,P2.3,P3.7 are connected to conveyor ,stirrer, tube light and buzzer respectively.P3.0 and P3.1 is connected to max 232.We use AT89C51 which is a low-power, high-performance CMOS 8-bit microcomputer with 4K bytes of Flash memory programmable and erasable read only memory (EPROM).



FIGURE 3.6.1 PIN DETAILS OF µC 8051

3.7 MICROCONTROLLER ALGORITHM

STEP 1: Select channel_0 to which load cell is connected.

STEP 2: Controller controls ADC0809 to get equivalent digital value.

STEP 3: This digital value (original weight) send to centralised data base

using serial communication.



STEP 4: Select channel_1 to which temperature sensor output is

connected.

STEP 5: Controller controls ADC0809 to get equivalent digital value of

sensed temperature.

STEP 6: This digital value (sensed temperature) send to the centralised

data base using serial communication.

STEP 7: Controller controls the bulb,motorstirrer,motorconveyor and

heater through driver circuit ULN2003.

STEP 8: MAX232 is interfaced with controller for communication with

centralised data base.

3.8 RELAY DRIVER CIRCUIT

Relay is an electro mechanical switch. Usually relays use an electro

magnet to operate a switching mechanism when several circuits need to

be controlled by one signal Current flowing through the coil ,the relay

creates a magnetic field, which attracts a lever and changes the switch



contacts. The coil current can be ON or OFF so relays have two switch

positions and they are double throw switches (NC and NO).

3.12 MAX 232

FIG:3.12.1: MAX232 CONNECTED TO SERIAL PORT AND µc

DESCRIPTION

Fig 3.12.1, MAX232 is a dual driver/receiver that includes a capacitive voltage generator to supply EIA-232 voltage levels from a single 5-V supply. Each receiver converts EIA-232 inputs to 5-V TTL/CMOS levels. These receivers have a typical threshold of 1.3 V and a typical hysteresis of 0.5 V, and can accept ±30V inputs. Each driver converts TTL/CMOS input levels into EIA-232 levels.

FEATURES

We connect a MAX 232 for the inter compatibility between the PC and µC signal levels.

It does signal level conversion automatically.



MAX232 parts are particularly useful in battery powered systems, since their low-power shut down mode reduces power dissipation to less than 5µW.

3.13 PARALLEL PORT CONNECTOR

DB25 is a parallel port connector from PC to microcontroller, which is connected to stirrer, motor, heater and bulb to the ports P2.2,P2.0(clockwise)P2.1(anti-clockwise),P3.2 and P2.3 respectively.

FIG 3.13.1: PIN DETAILS OF DB25



ALGORITHM TO INTERFACE PARALLEL PORT WITH CENTRALISED DATA BASE

STEP 1: Centralised data base will receive user input through parallel port.

STEP 2: Once the data is received through parallel port that data will be decoded by centralised data base.

STEP 3: After decoding the data it will receive particular message to controller.

STEP 4: So that the controller will process the acquired data.

6.1 FLOW CHART STEPS

STEP 1: Start the process.

STEP 2: Bring all motors to initial position.

STEP 3: Read temperature sensor value and send to PC.

STEP 4: DB25 parallel port is used to connect to the PC. It performs the ON/OFF operations of stirrer, motor, conveyor and heater on request.

STEP 5: Switch on sw2 of microcontroller.

STEP 6: Read weight from the load cell send to PC.

STEP 7: Rotate the conveyer belt motor clockwise for some time and stop.

STEP 8: Switch on bulb.

STEP 9: Check the segregation condition, if it is done, switch on sw1, if its not done complete the segregation process and again check for segregation condition.

STEP 10: If yes, switch OFF bulb or go to step 8 and repeat.

STEP 11: Rotate conveyer belt anti clockwise for some time.

STEP 12: Read the reduced weight of cocoons from load cell and send to PC.

STEP 13: Rotate conveyor belt motor in clockwise to drop cocoons.

STEP 14: Rotate conveyor belt motor in anti clockwise for initial position.

STEP 15: Repeat the process from step 3 for next set of weights of cocoons.



CHAPTER 7 : RESULT

FIG 7.1: OUTCOME OF THE PROJECT FROM FIG 7.1 RESULTS ARE AS FOLLOWS

Temperature :26ºC Today’s rate : 30rs Initial weight : 560gms Reduced weight : 490gms Wastage : 70gms Total weight : 490gms Cost : 14,700rs Balance : 87%



CHAPTER 8: APPLICATION AND FUTURE WORK

CONCLUSION

The semi automatic cocoons selection, automatic temperature and lights control circuits for the projects model is designed.

Tested & results are obtained, it is found that the energy utilized is minimum compared to the existing conventional system.

FUTURE WORK

If the mechanical design is of larger size so as to weigh 50 Kgs of cocoons at a time.

In this method, segregation process can be speeded up and the power can be much more saved.

Further the entire process to obtain the silk will be automated. Energy, Time & the man power can be reduced. It will improve the quality of the silk , saves lot of fuel (wood) &

maintain pollution free environment. It will give good accuracy of measurement of cocoons than that of

conventional method
