The Internet of Things is a new product under the development of the information age. The application and development of the Internet of Things technology has had a profound impact on the lives of modern people and has caused a radical change in the traditional home life. The application of WAN technology in smart home systems can make up for the deficiencies in traditional embedded gateways and improve the effectiveness of smart home systems in improving the living environment.

First, based on the Internet of things smart home system

(a) Internet of things . The definition of the Internet of Things varies according to the researcher. There has not been a single universally accepted definition. It involves various fields and is the result of integration of various technologies. Internet of Things is generally considered to be a network formed by Internet objects on the basis of standardized communication protocols, which can promote the development of society and have a certain impact on events in real life. The Internet of Things has a wide range of technologies. The core high-end technologies include wireless sensor network technology, Internet technology, radio frequency identification technology, information security technology, and nanotechnology. The composition of the Internet of Things is relatively complex.

(B) smart home . The smart home is a comprehensive application of high-tech technology that effectively interconnects all home facilities in a residential building to form an effective overall and intelligent control of the home facility to provide comfort and safety to people. Living environment. The introduction of smart homes has a major impact on the improvement of the home environment. With the development of science and technology, smart home systems are constantly being upgraded, and the networked smart home systems have been fully developed.

(c) Smart home systems based on the Internet of Things. Smart homes have been continuously upgraded with the development of wireless networks. The traditional smart home network uses an embedded home gateway to effectively connect the home system with the Internet, and can remotely control the home equipment, but the cost is high. The sharing rate of information resources is low and the cost performance is not high. The appearance of the Internet of Things has provided a new opportunity for the development of smart home systems. The smart home system based on the Internet of Things can set appropriate sensors in residential buildings to collect various types of information in residential environments, including people, facilities and the environment. This information is then connected to the IoT gateway via the Zigbee wireless network.

Second, the composition of the smart home system based on the Internet of Things

The smart home system based on the Internet of Things is composed of many parts. The main components are the home smart module, Zigbee wireless transmission, information processing unit, ARM central control platform, wireless communication and network communication. The IoT-based home intelligence control can effectively control the equipment in the house through the remote control end. When the house is stolen, intruded and other security threats, the intelligent system can perform automatic alarm processing and lighting and air conditioning in the house. Remote intelligent control.

The smart home system based on the Internet of Things has obvious advantages compared with the traditional smart home system. On the basis of the internet of things, the smart home system is more convenient and faster, and can realize the sharing of information resources on the computer network. The smart home system based on the Internet of Things realizes the remote monitoring and control of the home environment and equipment through the effective connection of various network ports, providing people with a more comfortable, safe and beautiful living environment.
