Overall architecture composition

Client: It is the device used by users, such as mobile phones, tablets, TVs, etc., used to receive and control home appliances. The design focuses on ease of use, convenience and aesthetics, and should also provide data analysis and feedback functions.

Server: It is responsible for storing the data of home appliances and providing services. It needs to be able to persistently store the status and data of home appliances, provide secure remote control services, and support data statistics and early warning functions.

Controller: It is the middleware connecting the client and the server. It supports multiple communication protocols, such as Wi-Fi, ZigBee, 4G, etc., and has automatic control functions, such as automatically opening curtains and automatically adjusting temperature.

Network topology and communication

Network topology: The network topology of the IoT smart home system is usually distributed. Each device has its own IP address and communicates through a router. At the same time, network security must be considered.

Communication protocol: Commonly used communication protocols include Zigbee, Wi-Fi, Bluetooth mesh and other wireless communication protocols to ensure stable connection and information transmission between various smart devices.

Functional modules

Sensor module: responsible for collecting home environment data, such as environmental parameters such as temperature, humidity, light, smoke, gas, and human body detection, and transmitting data to the central control unit.

Central control unit: receives sensor data, controls actuators according to user instructions, and handles events such as security alarms. It is the "brain" of the smart home system.

Actuator module: responsible for executing control instructions, such as controlling lights, air conditioners, curtains, security equipment, etc., to achieve actual control of home appliances.

Data processing and storage

Data storage: The system should be able to achieve real-time storage and remote access of data, while considering the security and reliability of data, so that users can view historical data and perform data analysis at any time.

Data analysis: By analyzing the collected data, the system can achieve intelligent control and optimization, such as intelligent control of home appliances based on environmental parameters and user behavior, improve energy efficiency, and provide users with a better user experience.
