Smart home technology architecture design concept and analysis

Focusing on the design concept of smart homes: convenience, comfort, safety, and energy saving, the smart home system is divided into five parts according to their functions, namely home security, environmental monitoring, home appliance control, energy consumption management, and smart medical care. And to achieve the local control terminal (ie, indoor units), remote control terminals (ie, smart phones and tablet computers) and Web pages such as viewing and control.

The core of the entire system is the home IoT gateway, which is the bridge between the underlying sensor devices, controllers, and control terminals. The home IoT gateway relays the data collected by the sensor and the control commands issued by the user and is a comprehensive device. Another comprehensive device is an indoor unit, which is generally located at the door of the home, and implements information interaction with the user of the entire smart home control system. The indoor unit occupies an important position in the entire smart home system. It realizes the centralized management and control of various systems in the home, and is connected to the door machine to implement the video intercom function and handle the access control problem.

The first choice for smart home should be to solve the security problem. The “Ministry of Construction of Intelligent Technology Demonstration Project for Residential Areas in the Whole Country” put forward by the Ministry of Construction on smart home development divides smart homes into several levels of standards, and integrates home security intelligence into smart homes. Prepared features. The traditional mechanical (security net, anti-theft window) home defense exposed some hidden dangers in the actual use, smart home security will be infrared detectors, window magnetic magnetic, smoke and harmful gas sensors, network cameras combined, using the control terminal Views and alarms provide users with a full range of intelligent security systems.

With the rapid development of social science and technology in today's society, people's living standards have been continuously improved. Everyone has paid more and more attention to the living environment. Monitoring of the environment has also become an indispensable part of the smart home system. By analyzing the environmental values ​​collected by environmental sensors such as temperature and humidity sensors, and using smart controls on lighting, curtains, air conditioners and other home devices to adjust the home environment, the interior of the home is kept in a comfortable environment. The home appliance control system establishes a home appliance control network that aims at comfort, convenience, and energy saving, and includes various home electric appliances and systems including various smart terminals (mobile phones, PDAs (Personal Digital Assistants), mobile communication networks, cloud servers, etc.) Together, they form an Internet of Things (IoT) application system based on the concept of a family life cloud, which can effectively control home appliances anytime, anywhere. The shortage of energy is a hot topic in today's society. The control of energy consumption in households brings benefits to users, and it also has a certain realistic meaning for the entire society. The energy consumption management and control system monitors and manages the energy consumption at home through the monitoring of large-scale household electrical appliances and the collection of data from three households (ie, electricity meters, water meters, and gas meters) at home.

In today's smart home systems, home medical care and elderly care functions are increasingly valued by people. Because of the impact of family planning, China’s population structure has also undergone tremendous changes. The 4+2+1 family member structure has become more and more obvious. There are more and more families without children or children who are not around the elderly. Elderly living alone and health care services pose serious challenges. In addition, how to better care for the cognitively disabled, disabled, chronically ill, infants and children in the family is also an issue that needs attention in building a harmonious society in China. Smart health care provides patients with chronic diseases such as mobility problems and heart disease, high blood pressure, etc., can monitor physical health at any time without leaving the home, and receive comprehensive medical services coordinated by health management centers and social logistics resources, which is of great practical significance. .
