Sticking to the outline of the Faculty, the theories and knowledge learned. During my graduation, I have gained more knowledge about building digital systems, as well as having access to algorithms, protocols, and programming skills that a student needs to master. With the enthusiastic help and guidance of our instructors and efforts in learning, exploring and learning, we have completed the report of our digital system building module.
In the process of making the report, despite my best efforts, I still have limitations in terms of research time, knowledge as well as experience, and there are still many mistakes. I look forward to receiving your comments and suggestions so that I can improve. 7 Chapter 1: INTRODUCTION TO THE TOPIC 1. Reasons for choosing the topic : I chose "Research and development of household toxic gas devices with sensors" as my graduation topic for the following reasons: • Firstly, smart home is a popular trend in the world when it helps to save time and effort thanks to the application of modern technology.
In Vietnam, this technology is also increasingly popular with users and becomes the preferred choice. • Secondly, I can apply much of the knowledge I have learned to the topic such as knowledge of programming microcontrollers, knowledge of temperature, humidity, light sensors,. or proficiency in communicating. This is also an opportunity for me to learn more new knowledge, practice self-control and sense of responsibility at work.
• Third, under the popularity of smart home technology today, the need to learn and develop becomes more urgent and especially the safety in each house is indispensable. • Finally, with the aim of creating a controller with basic features, applicable to my own home, it has created more motivation for me to carry out this topic.The goal of the subject : Understand the characteristics, features and structure of the smart home. Master the features of lighting system, gas leak alarm system, burglar alarm. in smart home.
Design and process a house controller model with the following basic features: • Capable of turning on and off the electric lights in the house manually or automatically according to the scenarios. • Read and process signals from sensors. • Burglar alarm, gas leak. • Can be controlled and monitored remotely by a phone connected to the Internet.
Build a house model to be able to test the above controller.Object and scope of the study: The range of smart homes is very wide, from infrastructure to functions and modes of operation. In the thesis, focus on researching and designing the system of turning on and off the appliances in the house according to the scenario, burglar alarm, gas leak alarm, fire alarm. Remote control and monitoring via the Internet.Meaning of the topic: A useful document for those who are just starting to learn about smart home systems. Especially a reference for those who want to design and manufacture a safety alarm system with smart home with basic features.What is a smart home? Smart home or smart home system is a house/apartment equipped with intelligent automatic systems with reasonable layout, these systems are capable of self-coordinated activities in the house.
According to the living habits and personal needs of the owner. We can also understand a smart home as a whole system in which all household electronic devices are linked to a central control device and can coordinate with each other to perform the same task perform a function. These devices can come up with a pre-programmed way of handling situations, or be controlled and monitored remotely for the purpose of making life more comfortable, safe and contributing to rational use resources. A system that regulates the illumination levels of the lighting system to help save electricity and match the scene, such as placing soft lights for nighttime events, is one of the most basic examples of a smart home.
Additionally, the system has features for controlling temperature, monitoring camera systems, automated door locks, and anti-theft systems. Other, more cutting-edge uses for smart homes include home entertainment control systems with speakers of various sizes, phone systems, intercoms, watering systems, etc. These functions can be performed by connected indoor devices so that the central computer system can monitor the status and make appropriate control decisions. Smart homes have been envisioned in sci-fi works for many years, but it only became a reality in the 20th century following the widespread development of electricity and rapid advances in information technology.
Smart home technology is a reality, and it's becoming increasingly sophisticated. Encrypted signals are sent through wires, wireless networks to switches, pre-programmed electrical outlets to operate appliances and electronic devices in the house. Home automation is especially beneficial for elderly and disabled people who want to live independently. The installation of smart products gives the home and its owners many benefits – similar to those that technology and personal computers have given us 10 over the years – including: Convenience, saving time, money and energy.
Basic components in smart home: 2. Lighting management system: Lighting devices such as incandescent bulbs, neon lights, night lights, decorations. are used a lot. Therefore, if the lighting is not coordinated properly, it will lead to light "pollution".
In addition, such lighting also wastes electricity, reducing equipment life. Besides, the number of lights used for lighting is quite large, homeowners will encounter minor inconveniences in turning on and off, adjusting the brightness accordingly. The lighting system will be integrated with other systems or will be separated for independent control. The solutions are aimed at optimizing the system and making it easier for homeowners to control.
Combined solutions will be taken into account for maximum automation. Access control system: When the homeowner is away, it is very important to control the entry and exit systems in the house, to help prevent theft, etc. The smart home provides an access control system that allows the owner to manage and grant permissions. login” for family members and loved ones.
The door system will be installed with fingerprint locks or magnetic cards. to identify people in the house or guests to grant "login" rights. In addition, it is also possible to use the facial or voice recognition system. Every time there is a new event, this access control system will also trigger other systems to keep track of user-generated changes.
Sensors and alarm systems: In every system of the house, the sensor system is a crucial component. The sensors are in charge of transmitting the measured parameters to the central processor for an appropriate answer for each data packet. and respond to each circumstance appropriately. Basic sensors such as temperature sensor, humidity sensor, gas sensor, pressure sensor, infrared sensor … 2.
System of state control switches: The system of switches and display panels will provide information as well 11 as receive control commands from the owner. Ensure two-way interaction between members and automated system. System includes: remote controls, wall switches, HMI interactive control panels, smartphone… 2. Central processing system, remote control and monitoring: The smart home is highly appreciated and different from normal houses because it is equipped with a control system and all changes and automatic control in the house are handled uniformly through the system.
It has an important role, doing the task of linking other systems in the house together, coordinating the operating system in a rhythmic manner according to the pre- programmed impact conditions. We call these scenarios – or environmental conditions in the house. Recently with the development of artificial intelligence (AI), the process of controlling the house has become more sophisticated. Some typical combinations: • Lighting system with Central Processing System can learn and act according to user's habits.
Or will the lighting devices work on a preset time cycle. • Lighting system combined with Sensor system provides the ability to automatically control light such as: lights automatically turn off when no one is in the room. • Warning system combined with lighting system: when there is a problem such as fire, explosion, theft detection. the lights will flash continuously, and there will be a siren to signal.
• The sensor system combined with the central processing system reports the status of electricity storage in the UPS, reports the water level in the tank. to ensure the supply for daily living needs. • Multimedia entertainment system combined with lighting system to bring relaxing moments for family members. Development situation at home and abroad: 2.
For the situation abroad: The smart home industry is regarded as having tremendous growth potential on a worldwide basis. Technology behemoths like Microsoft, Apple, Google, Samsung, and others are enthused by this trend and are working on several related 12 initiatives.
