What Is an Embedded System?
Embedded system is the combination of electrical and mechanical devices which has a dedicated function. It is Implemented In many electrical and electronic device which is frequently used in our day to day life. Embedded system can be a microcontroller or microprocessor-based systems. The complexity of the circuit can be reduced using embedded system technology with high performance and reduction in cost.
Classification Of Embedded System :
Embedded system can be classified based on the performance of an embedded system and microcontroller performance
Based on embedded system performance :
- Real-time embedded systems
- Stand-alone embedded systems
- Networked embedded systems
- Mobile embedded systems
Based on a microcontroller embedded system :
- Small-scale embedded systems
- Medium scale embedded systems
- Sophisticated embedded systems
Application Of Embedded System :
Embedded system has seen a major growth as mobility becomes an essential human need in this modern world.
Embedded system is present in various industries like Automobile, Aeronautics, Energy Control, mobile telecommunication, Global transport industry or e-payment solutions and so on.
The major application of Embedded system in Automobile sector :
Embedded system is typically a microcontroller system with one or few dedicated functions. Embedded system in automobile industry helps to improve the safety, cost, performance, and comfort. In recent decades, there is a rapid increase in the growth of the embedded electronic system in the automobile industry. There is 100 ECU’s are present in the top cars whereas each unit controls one or more electrical systems or subsystems in a motor vehicle.
Technologies used in today’s vehicle :
- Air bags
- The black box
- Anti-lock brake system
- Adaptive cruise control
- Drive by wire
- Satellite radio Eg: XM
- Telematics Eg: Onstar
- Rain-sensing wipers
- Emission control
- Traction control
- Automatic parking
- In-Vehicle entertainment
- Heads-up display
- Night vision
- Backup collision sensor
- Navigation systems
- Tire pressure monitor
- Climate control
The major application of the embedded system in the Aeronautics Sector :
Embedded system is an advanced technique that is present in many subsystems and the main system in the aerospace industry that helps to control the desired section. It is present in the various system that includes Flight data recorders, internal/external video surveillance system, flight management systems, various sensor systems, engine control systems and much more. Aerospace is highly dependent on Embedded system than other industries and it is expected to be increased in the future.
The major application of the embedded system in Energy control :
Embedded system is used in the Energy control system like Windmill and nuclear plants. Embedded system is used to check the health of the wind turbine by integrating the sensor in the blade to observe the changes in blade structure. This will help us to protect from blade breaks. "We want to develop an integrated sensor system which can carry out many tasks simultaneously. It will be needed in a future remote monitoring system for wind turbine blades. No single type of sensor will be able to supply all the necessary information to estimate the condition of the turbine blade because there are many potential sources of errors and damage in blade materials," says Malcolm McGugan and Kaj Borum from the Materials Research Division at Risø DTU.
The major application of the embedded system in the Biomedical field :
Embedded system technologies play an important role in the Biomedical application in diagnosis, prognosis, patient management, and telemedicine. Embedded system is used in all biomedical instruments such as blood glucose monitors, blood pressure monitors, patch detection of various diseases like dengue, malaria, and portable ECG (electrocardiogram), CT (computed tomography), defibrillators, CRT-D device, digital thermometers, digital flow sensors. Biomedical professionals are looking for the innovating compact and constraint device for user-friendly, faster, smarter and reliable use.
