Abstract: In ancient time, submarines are definitely in cigar-shaped. Their layout in beginning submarines
looks noticeable often known as "teardrop hull". The hydrodynamic drag is decreased whenever underwater,
but it reduces the sea-keeping abilities and improves pull while surfaced. Because the restrictions of the
propulsion techniques in very beginning submarines powered them to manage surfaced most of the time, their
own hull models were a compromise. Mainly because of the slower submerged speeds of those subs, commonly
well below 18 km/h, the improved drag for submerged journey was acceptable.

I. Introduction
Submarine is a watercraft able of individual process under the sea. That varies from a submersible,
which has a much more minimal under the sea capacity. The expression many typically relates to a huge,
crewed, self-directed vessel. It is also often used traditionally or colloquially to refer to slightly managed
automobiles and robots, as well as medium sized or compact vessels, like the midget submarine as well as the
wet sub. Applied as an adjective in phrases such as submarine wire, "submarine" means "under the sea". The
noun submarine evolved as a reduced form of submarine boat. For causes of naval traditions, submarines are
generally called to as "boats" instead of "ships", irrespective of their size.
II. Block Diagram
The block diagram for this system is shown in the figure 1,
It consists of two power supply (L1117), two motors, two
Arm controller (LPC2148), two LCD display, TRIAC, Buzzer, Switches, Driver (L293D), Temperature sensor
(LM35), Smoke sensor (MQ6), Ultrasonic sensor, UART and a RF Receiver.

III. Microcontroller (LPC2148)
We selected LPC2148 microcontroller for our project execution, because of its speed. It is a 32-bit
microcontroller with 32kb to 512kb flash memory. This controller supports totally 2 serial ports here we are
using 2 microcontrollers for master and slave communication, both microcontrollers are communicating with
UART communication. The slave controller contained sensors and it will send the data to the master controller
the master will display this data in the LCD.

The slave section operates motor and buzzer and master drives the hull motors .the master will take
different decisions related to the hull, by collecting data from the keypad and RF receiver.
IV. Gas/Smoke Detector (MQ 6)
A smoke detector is a device which detects the presence of smoke within an area, usually as part of a
safety system. This type of equipment is used to detect a smoke leak and interface with a control system so a
process can be automatically shut down. A smoke detector can also sound an alarm to operators in the area
where the leak is occurring, giving them the opportunity to leave the area. This type of device is important
because there are many type of smokes that can be harmful to organic life, such as humans or animals.
Fig.2 Smoke/Gas Detector (MQ6)
V. Tererature Detector (LM35)
The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly
proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear temperature
sensors calibrated in ° Kelvin, as the user is not required to subtract a large constant voltage from its output to
obtain convenient Centigrade scaling. The LM35 does not require any external calibration or trimming to
provide typical accuracies of ±1⁄4°C at room temperature and ±3⁄4°C over a full −55 to +150°C temperature
range.
Fig.3 Temperature Detector (LM35)
VI. Principle Of The Ultrasonic Detector
Ultrasonic sensors emit short, high-frequency sound pulses at regular intervals. These propagate in the
air at the velocity of sound. If they strike an object, then they are reflected back as echo signals to the sensor,
which itself computes the distance to the target based on the time-span between emitting the signal and
receiving the echo.

Fig. 4 Detection Of Ultrasonic Sensor
Virtually all materials which reflect sound can be detected, regardless of their colour. Even transparent
materials or thin foils represent no problem for ultrasonic sensor. Micro sonic ultrasonic sensors are suitable for
target distances from 20 mm to 10 m and as they measure the time of flight they can ascertain a measurement
with pinpoint accuracy. Some of our sensors can even resolve the signal to an accuracy of 0.025 mm. Ultrasonic
sensors can see through dust-laden air and ink mists. Even thin deposits on the sensor membrane do not impair
its function. Sensors with a blind zone of only 20 mm and an extremely thin beam spread are making entirely
new applications possible today: Fill level measurement in wells of micro titer plates and test tubes, as well as
the detection of small bottles in the packaging industry, can be implemented with ease. Even thin wires are
reliably detected.
VII. About RF
1) The STT-433 is ideal for remote control applications where low cost and longer range is required.
2) The transmitter operates from 1.5-12V supply, making it ideal for battery-powered applications.
3) The transmitter employs a SAW-stabilized oscillator, ensuring accurate frequency control for best range
performance.
4) The manufacturing-friendly SIP style package and low-cost make the STT-433 suitable for high volume
applications.

XI. Conclusion
The mechanism is cheap and flexible for testing submarine by using alarm and monitoring control.
This control setup use for submarines which has both digital and analog circuit boards interface. The proposed
designed control system control several types of self-running process control station, each type is dictated to
certain task. The alarm system is connected to sensors all over the place in the submarine and always monitors
them, if any sensor reading is outside the preset limits we get an alarm. The observing setup can capture any
alarm condition and store it in hard disk or printer with timestamp. Including to that it will be applied as basic to
test variety of all ship condition from the link. They require to shorten manning stage led to the improvement of
automated controls essential schemes for the engine room plant which allowed unattended operation of devices
spaces. With vessels capable of safe functioning for any stage of time in this mode, all the handling functions
and following features are gathered combined in a system controls Room for sample. The system take small
energy in arrange of only a few mill amperes per interface and drivers is safeguarded like that it frequently holds
the consumer from harmful sensor that was in place or developed inappropriately. This system feature increases
the setup and decreases the slide down time. The direct development layout interface enables the multiple use of
the design in a variety of cases specifically when putting in or improving sensor or method in the submarine.
Engaging this system high speed for testing is obtained and will be utilized to test more advanced styles
according the specifications.
