Abstract(1/2)
• A waste water handle system was
designed and constructed.
• The sampler operation was controlled
with a low cost and efficient PICmicrocontroller.
4
Abstract(2/2)
• It could operate under the industrial
environment.
• The human intervention factor was
reduced to minimum so that the human
health was protected against the
chimecally waste water.
5
Introduction(1/2)
• Rivers are the main sources of the water.
Detection is implemented by inspecting lots of
samples that are collected from these sources at
different times.
• Our device has been designed to automatically
collect the required amount of sample in the
predefined time intervals.
6
Introduction(2/2)
• The thing the user should do is to define the
beginning and the end of the collection process
and the interval duration each sample will be
collected in. The system is running according to
these values.

Pic(Programmable Integrated Circuits)
b. PIC Instruction Structure
• Each of the instructions written in our programs
occupy 14 bits on PIC (pic16c84) .
• First 6 bits of these 14 bits recognize the
instruction and the remaining 8 bits carry the
related data.
9
THE STRUCTURES AND OPERATION OF
THE SYSTEM
• The system includes the parts named as
mainboard, display card and feed card.
10
THE STRUCTURES AND OPERATION OF
THE SYSTEM
• Mainboard is the part where the microcontroller
component is built in and all the controls and
adjustments take place.
• The value and the quality of the entered clock can
be inspected by means of display card.
• Feed card is the part that provides the ±5V DC
voltage all the ICs need and the ±30V DC voltage
that is needed to feed the step motor and the 220V
AC voltage for the pump.
11
THE STRUCTURES AND OPERATION OF
THE SYSTEM
12
THE STRUCTURES AND OPERATION OF
THE SYSTEM
• The PIC is programmed to provide collecting the
required amount of the water sample in
predefined intervals according to the
information that are entered by the keys.
• Step motor control card is made of two circuits
which are called as stator trigger sequence
generator and stator driver circuit.
13
THE STRUCTURES AND OPERATION OF
THE SYSTEM
Stator trigger sequence generator
14
THE STRUCTURES AND OPERATION OF
THE SYSTEM
Stator driver circuit
15
THE STRUCTURES AND OPERATION OF
THE SYSTEM
• When the shift register is initialized the load data
inputs (3rd, 4th , 5th and 6th pins) are set to 1001
and mode control inputs are programmed for
parallel load.
• Passing from one sequence to another of the
sequence generator is provided by microcontroller
component.
• The ABCD outputs of the sequence generator can’t
drive the stator bandages of the step motor directly .
• A drive circuit has been placed between the
sequence generator and the motor .
16
THE STRUCTURES AND OPERATION OF
THE SYSTEM
• The pump control card is made of an opto triac
that provides physical insulation and a triac that
implements current control.
• When the PB7 pin of the PIC is on, the optotriac
triggers the gate pin of the triac to make it active.
• When the gate pin of the triac is active it passes
the current and the pump begins to operate .
17
THE STRUCTURES AND OPERATION OF
THE SYSTEM
Pump control circuit
18
THE STRUCTURES AND OPERATION OF
THE SYSTEM
• Display choosing and loading level and key
control level are also controlled by the PIC and
implemented with suitable integrated circuits.
• Display level is made of a 4 digit clock
component by means of which the entered
values are inspected and a menu part that
determines the quality of the entered value.
19
CONCLUSION
• Collecting samples from water resources such as
barrage and rivers and testing these samples to
determine the damages they give to the
environment.
• The system is designed to automatically
implement all the functions that are required to
be included in garbage water sample collection
devices.
20
CONCLUSION
• It is possible visually inspect the drink water by
means of a simulation program that will be
implemented for the device designed in this
study.
• This study will obtain a very useful interface and
be ready to be used in the life.
