Polaris Smart Grid Online: Application of Internet of Things in Smart Home
Most of the traditional methods are to form a smart home system through a wired method. This method not only requires the participation of professionals but also special company maintenance, and has a long construction period and poor system flexibility. The IoT smart home is an organic integration of wireless Internet of Things technology and smart home, so as to build a smart home system that is simple to install, easy to use, easy to maintain, and expand as you like. According to the industry-wide IoT architecture, the Internet of Things can be divided into perception, network, and application layers.
Perceptual layer
Comprehensive perception is a feature of the Internet of Things technology. It uses information such as radio frequency identification (RFID), two-dimensional codes, GPS, cameras, and sensors to sense, capture, and measure information, and collects and acquires information from sensing objects anytime, anywhere. In smart homes, the perceived objects are divided into the family environment in which people live and the people themselves. The eight major subsystems in the traditional smart home can be used as the implementation device of the perception layer. In addition, the Internet of Things smart home system also uses many typical sensing technologies, such as wireless temperature and humidity sensors, wireless door sensor, window magnetic, wireless gas leak sensor and so on.
Network layer
The Internet layer in the Internet of Things includes a converged network formed by various communication networks and the Internet. In addition, it also includes the intelligent processing of mass information, such as the home network management center, information center, cloud computing platform, and expert system. In the smart home, the network layer must not only have the ability to operate the network, but also improve the ability to operate information, such as the application of the database. In the network layer, especially the two issues of reliable transmission and intelligent processing are handled.
Application layer
The application layer is a set of solutions that combine the Internet of Things technology and smart home professional technology to achieve intelligent home applications. The IoT finally realizes the deep integration of information technology and traditional homes through the application layer. This is mainly reflected in smart grid applications, home medical applications, multimedia entertainment applications, home security applications, and home control applications. In addition, the application layer also provides home service providers with third-party excuse to provide services that facilitate people's life.
Why Smart Homes Are Not Popular in China
First, although China’s telecommunications-led China Communications Standards Association (CCSA), Lenovo-led domestic IGRS Information Resource Sharing Services (IGRS) and Haier-led e-Jiajia have all submitted their own National standards for smart home agreements, however, have not been well followed in the industry. Because the product communication protocol is not uniform, all manufacturers produce according to different interface standards and protocols. Therefore, interconnection, interoperability, and interoperability between products cannot be realized. Information between subsystems cannot be exchanged. These make many households The service became a mirage.
Second, the smart home industry has been developing in China for 10 years. The smart home product market is also concentrated in two areas: security alarms and intelligent controls, and limited product types. The research and development of products related to smart home systems employs high-tech technologies, which are fast-evolving and risky. Many companies are unwilling or have insufficient funds to invest in R&D.
Third, the market acceptance is low. At present, most ordinary residents still do not realize the convenience of smart homes. Among those who are concerned about smart homes, they are only concerned with some functions related to daily life, such as security, property, and home services. Advanced control functions, such as information appliances, are too far away. In addition, the immaturity of new technologies, problems, and higher costs also deter ordinary customers.
Fourth, the smart home system will be a multi-industry cooperation platform in the future. At present, China’s social cooperation system is still not sound enough. The traditional business philosophy and huge market competition pressures between all industries are all in the industry. Even other related industries seize the opportunity to expand their market share rather than open their own product interface technology and related agreements. In addition, the slow development of industries related to smart homes and the imperfect industrial chain are also reasons for the difficulties in cross-industry cooperation.
