[attachment=21922]
INTRODUCTION
Along with the development of science and technology,
especially the development of artificial intelligence
technology and the high-energy weapons, the competition
among the countries have intensified. Therefore, the rapid
development of smart weapons began. Water torpedoes and
the kind of “mines and torpedoes” have emerged as a
hybrid weapons in this period.
THE PRINCIPLE OF SYSTEM INTRODUCED
Ultrasonic Ranging Principle
Ranging principle: ultrasonic frequency is higher than
20 KHz. In order to use ultrasonic as a test method,
ultrasonic waves needed to be generated and received. The
device fulfilled this function is ultrasonic sensor, which is
known as the ultrasonic transducer or ultrasonic probe. An
ultrasonic sensor with transmitter and receiver has the dual
role that it can send and receive acoustic. Ultrasonic sensor
uses the principle of piezoelectric effect to mutual
conversion of electric and ultrasonic ultrasound is the
launch time, power conversion, firing ultrasound, and the
receipt of the Echo, will be converted into ultrasonic
vibration signal. [1]
The general principle of Ultrasonic Ranging is
transit-time method TOF (time of flight). Firstly, the time of
ultrasonic, from launch to encounter obstacles and return,
should be measured. Then, twice the distance of the sound
source and the obstacles can be obtained by multiplied the
speed of the ultrasound, namely: D = ct / 2.
Where D is the distance between sensor and the barrier
with m, c is ultrasonic velocity, here with 340 m / s, t is the
total time from sent to the receiver, with s. [1]
See back effect
The open circuit is made up of two kinds of conductors.
If the two nodes of the conductors exist temperature
difference, EMF E will be generated in the open circuit.
This is See back effect. The EMF generated by the See back
effects is called temperature EMF [2].
. System Principle
Water torpedo with solar plate and floating devices can
suppository in the electronic chain in the specified area, the
premise is ensuring that the solar energy can irradiation the
place to make the system can work long-term. When
infrared sensors received high concentrations of infrared
receiver, circuit installed in the chain of strobe a high
electrical level, locked out of water torpedoes rotary motor,
activated water torpedoes, and make it escaped from chains.
Track enemy vessels according to the design of thermal
tracking system based on See back effect and locate the
enemy ship based on the principle of Ultrasonic Ranging,
and when the distance of the water torpedo and target
enemy ship is in the limit the scope of the explosion,
MCS-51 will ignite Monolithic Water-detonated torpedo.
Explosives requirements: there is sufficient power, such as
N2 type of explosives. Explosion: 8 m.
HARDWARE SYSTEM INTRODUCED
Strobe circuit and infra-red detectors
When the infrared detector received infrared,
corresponding unlock signal was strobe for selective circuit,
issued to the motor torpedo water locked to the outside, to
unlock the results, while strobe AT89C51.
