The Real-Time Embedded System Applications

Have you ever thought about the growth of embedded systems?

Believe it or not, there are many examples of embedded systems in everyday life. These systems are commonly found in consumer, enterprise, cooking, automotive, medical, and commercial applications. From computers to electric toys and calculators, you face embedded systems even without knowing that.

To begin with, let's find out what is an embedded system. An embedded system is a computer system within a larger complete system. Unlike the general-purpose computer, such systems manage only one or two specific functions. In most cases, embedded systems have real-time computing constraints.

Sounds difficult?

There's no better way to learn embedded systems than starting from sketch level even if it may be difficult at first blush. For example, many EEE, ECE and EIE students need to accomplish embedded systems projects. However, they often fail to get homework done without professional help. When they turn to professionals, they understand how to shift from the basic knowledge of electronics to more complicated tasks. As a result, students get interested in doing the embedded system project.

To dive into the understanding of the embedded system, let's find out more about its subcategory, real-time applications. It's a type of computer system that has timing constraints. In other words, it reacts to external events or input stimuli in real time and the responses are produced within a predefined time. There are two types of real-time systems, hard (should meet the deadlines strictly) and soft (have some relaxation in meeting the deadlines).

From consumer electronics to industrial equipment, embedded system applications are everywhere. Any proof needed?

Here's the list of real-time embedded system applications:

1. Smartphones

Most modern smartphones are based on the embedded real-time operating systems. And these gadgets help users make the most out of them without putting much effort. From face detection to Internet connectivity over GPRS, smartphones process actions in real-time to serve users.

2. Smart TVs

Modern smart TVs have sophisticated features and embedded systems that allow users to control the TV remotely or recognize a face to select a proper TV program in a real time. Moreover, most smart TVs also help to connect with external devices (USB flash drives, mobile phones, etc.), so the main intention of this project is to react to inquiries fast.

3. Wireless Routers

While it's hard to imagine our lives without WI-fi, we rarely think about the complicated actions it requires. The router has an embedded system that uses the signals from a cable and transmits them wirelessly to the devices. It also collects the data from those devices and sends it through the cable, and everything happens in the moment.

4. GPS Navigation Systems

In the digital era, there's no need to know the roads to be a confident driver. The embedded GPS systems establish a real-time connection between the vehicle and the territory to provide the driver with a fresh and updates data.

5. Cars

All modern cars and motorcycles have embedded systems that work in real time to provide users with safety features – ABS (anti-lock braking system). It allows vehicles to have traction with the road and prevent them from locking up and skidding while braking.

6. Road Safety Systems

With the rise of automobile industry, traffic jams have become the main problem in big cities all over the world. Real-time embedded systems help to show off the traffic density with the signal timing changes so that drivers can avoid traffic jams. Moreover, these systems controls rash driving to minimize the risks of car accidents.

7. Street Light Control

Implementing real-time embedded systems is a next step in optimizing the usage of electricity. The main idea is to recognize the movements on the highway and illuminate the road automatically when needed. The light switches on when the vehicle comes closer and then it switches off.

8. Flight Control Systems

All aircraft vehicles have two flight modes – manual and autonomous ones – and the aim of embedded systems is to ensure a safe flight. From triggering the motors for speed to communicating with the ground station, these systems allow autonomous flight control.

9. Industrial Temperature Control

The industrial applications rely on a controller that regulates the optimal temperature level. Since all industrial devices have a certain temperature level that can vary from -55C to +125C, it's important to keep an eye on its controlling to guarantee the proper functioning. Thus, industrial temperature controllers come in handy.

In a Word

The real-time embedded applications are applicable in various fields, and most people use these systems even without knowing them. With the growth of technologies, it's important to understand the role of these systems, how they work, and where you can find them in everyday life. The above-mentioned applications are just a few examples of real-time embedded systems that can provide you with a better understanding of the topic.
