2. OBJECTIVES
⢠The main objective of this concept to provide water to the farmers on their
request & to maintain the water levels and flows in the canals using
programmable logic controller.
⢠The design and implementation of automatic canal control system is
achieved through Function Block Diagram (FBD) programming.
⢠The implementation is done by using controller, driver IC &
communication protocols.
⢠The water data logging system is done through microcontroller & PLC
interfacing.

4. INTRODUCTION
⢠Now a days water crisis is major issue.
⢠50% water lost to leakage & system inefficiencies.
⢠Only 16% of farmers aware of irrigation efficiency technologies.
⢠80-84% of water consumed for agriculture in India (by-MoWR)
⢠In 2010, demand of water for agriculture was 813 billion cubic meter,
In 2025, demand of water for agriculture will be 1093 billion cubic meter.

⢠Canal automation is becoming widely used to improve the operation of
canal systems and to conserve water.
5. ⢠Many older canals are being modernized with data collection, telemetry, and
control equipment that helps canal operators better manage their water.
⢠In this project we are focusing on above issues & to provide sufficient amount
water to farmers on their requirement automatically.
⢠In water canals & sub-canals, water levels are also maintained with the help of
PLC (Crouzet) & millanium-3ac software.
⢠Sensors, gates, PLC, Function Block Diagram (FBD) language, GSM module
etc are the main components/devices used for the project.
⢠The used water by farmer data is also logged through software.
⢠So water data logging system is also available, for used water data record.
6. LITERATURE SURVEY
⢠The first research program in canal automation began in 1966 by the Bureau's
Mid-Pacific Region.
⢠In 1970âs, an electromechanical relays were used in operation of canal
automation in western U.S.
⢠In 1990âs, very few successful operations of PLC based automation systems.
⢠In Arizona USA, on the Salt River Project Canal system an automatic control
system was proposed. This system automates and enhances functions already
performed by operators
⢠Today, canal automation field is being develop & SCADA can be installed for
controlling whole system.
7. OLDER & EXISTING SYSTEMS
Colvin controller
Little-Man controller
Drawback:
Devices are limited to controlling, only the smaller canal system flow can be
controlled
8. OLDER & EXISTING SYSTEMS
EL-FLO (Electronic Filter level offset)
controller
Drawback:
It can be maintain big canal system but fails
to control upstream and downstream level of
water
9. PROPOSED CONCEPT
Sensors:
S-1: sense water level between G-1&G-2
S-2: sense water level between G-2,G-3&G-5
S-3: sense water level between G-3&G-4
S-4: sense water level between G-5&G-6
S-5: sense water level between G-6&G-7
Gates (Solenoid Valves):
G-4: Farmer-1
G-7: Farmer-2
10. PROPOSED CONCEPT
⢠In this concept, we have consider two farmers which demands for water.
⢠When farmer-1 is requesting for water, he will send his request through sms.
⢠As soon as request granted by PLC, water level of sub-canal will automatically
checked by software.
⢠If sufficient water level is available then gate-4 (for farmer-1) will automatically
open for specific time duration.
⢠For farmer-1 sufficient water in sub-canal is necessary condition & if there is not
enough water level in sub-canal then sensor-3 will send the signal to PLC &
gate-3 will open.
11. Comparison between existing canal control system and proposed canal
control system
⢠Existing System:
⢠Semi automatic.
⢠Programming constraints are more
⢠Data Control Unit (DTU),
Data Collection Unit (DCU) are
available
⢠High cost
⢠Maintenance is more
⢠Fault detection is not easy
Proposed System:
⢠Fully automatic
⢠Programming constraints are
minimum
⢠DTUâs & DCUâs work simply done
by remote station server (laptop)
⢠Cost is low
⢠Low maintenance cost as we have
used PLCâs as compared to existing
one.
⢠Fault detection is easy as compared
to existing system
15. SYSTEM DESIGN
In system design
Step-1) Design of power supply-
Power Supply-24v DC,5Amp
Step-2) Selection of PLC
Step-3) Selection of inputs & outputs
16. SELECTION OF PLC
For the selection of PLC, the following considerations are important
i) Type of PLC- whether compact or modular?
ďź In this we have used compact PLC, because it is cheaper & our input
& outputs are fixed. So we have selected CD-20 as on requirement.
17. ďź
ii) Power Supply of PLC- 24vdc/12vdc/24vdc/230vac/24vac
We have used 24vdc power supply PLC
18. SELECTION OF INPUTS/OUTPUTS
⢠Depends on proposed concept we require five sensors & two gsm modules for
farmers notification. So total digital inputs required are seven.
⢠And we have total seven gates on canals & sub-canals, we have placed
solenoid valves, these are also digital types, so total digital outputs required are
seven.
⢠By considering above inputs/outputs, we require PLC having minimum seven
digital input & seven digital outputs.
⢠So we have to select Crouzet Make PLC with minimum 7-DI & 7-DO
⢠After going through catalog , we find CD-20 is perfect PLC for our
requirement.
19. Technical Specifications for Crouzet CD-20 PLC:
Type- CD-20
Power Supply-24VDC
Inputs- 6 DISCR+ 6(0-10V)
Outputs- 8 RELAY
23. FRONT PANEL VIEW OF PLC ON SIMULATION WINDOW
In the front panel of PLC,
Inputs are at upper side- 123426 (DI)
BCDEFG (AI)
Outputs are at lower side- 12345678 (DO)
25. PROGRAMMING LANGUAGES
⢠In different types of PLCâs, different programming languages are used-
Sr No PLC Programming Language
1 Siemens i)Ladder
ii)FBD (Function Block Diagram)
iii)IL (Instruction List)
iv)ST (Structured Text)
v)SFC (Sequential Function Chart)
2 Allen Bradley i)Ladder ii)FBD
3 Modicon i)Ladder
4 Crouzet i)Ladder ii)FBD
5 Schneider Electric i)Ladder ii)FBD
6 Mitsubushi i)Ladder ii)FBD
7 Delta i)Ladder ii)FBD
8 Messung i)Ladder ii)FBD
27. INTERNAL BLOCKS OF MODEL
⢠Timer A-C: This timer is used in programming for controlling On/Off
time of gates
Selection of timer block in software window Function A-C Timer:
28. FUNCTION A-C TIMER:
Double clicking on timer block we got this parameter window on
programming screen, from this we can set ON delay & OFF delay
