Embedded System
An embedded system is a fixed or
programmable combination of computer hardware and software designed for a
specific function or function within a large system. Embedded systems can
include industrial machines, agricultural and processing plants, automobiles,
medical devices, cameras, devices, airplanes, vending machines, and mobile
devices.
Applications of Embedded system
Embedded system
is used in almost every industry. Communications, manufacturing, military
defense and scientific research are just a few of the many sectors in which
people rely on them to achieve their goals and work more efficiently by
reducing manual processes.
A good example of a real-time embedded system
application is a weapon defense system whose sole task is to protect naval
destroyers by shooting down incoming missiles. Weapon defense system consists
of three subsystems: a weapon launch system, radar system, and control system.
The weapon launch system and radar system are controlled, but the control
system functions as a command and decision system.
Radar systems monitor potential threats such
as incoming missiles, measure their coordinates, and transfer them to the
control system. The control system determines the threat level possessed by the
target according to the information collected from the radar system. The
command and decision-making system determines various target parameters such as
flight path, points of influence, and speed. Based on these parameters, the
control system activates a weapon firing system that fires until the target is
completely destroyed. Communication between the radar and the command and
decision making system is real-time.
Embedded System Real-Time Applications
Embedded systems have applications ranging
from consumer electronics to entertainment equipment, weapons to medical
equipment, industrial equipment, academic equipment, and aerospace control
systems. Embedded systems are also used in various industries such as office automation,
banking, finance, consumer electronics, security, telecommunications, personal
vehicles, and instrumentation. Below is a working example of the embedded
system.
Embedded System In Highway Speeding Detection
It relies on a highway speed checker device
that senses highway speeds and notifies traffic authorities if they notice the vehicle that violates defined highway speed limits.
Embedded System In Street Light Control
It works by detecting the vehicle movement on the
highway and turning on street lights before approaching vehicles to arrive. After
the vehicle has passed, the streetlights will go out to save energy.
Embedded System In Vehicle Tracking
Vehicle tracking works by using GPS to
determine the exact location of the vehicle. They are used to control theft and
possible criminal activity. GPS modems send messages to specific mobiles that
store data. Location information regarding longitude and latitude values is
displayed using an LCD display. The microcontroller regularly checks the GPS
modem.
Embedded System In Home Automation System
This involves using a home automation system
with Android applications and remote-based controls. Remote operation is performed
by Android OS-based phones and tablets. The Android application acts as a
transmitter, sending on and off commands to the receiver to which the load is
connected.
These are just a few examples of embedded
systems in the world today. Embedded systems act as a core control for
interfacing peripheral devices and are therefore found in many applications
using various electrical components.
