The system is based on voice and Internet of things control of smart home system, is developed by domestic CH32V307 chip. This project combines voice short-range control with IoT far/short-range control to realize convenient operation of smart home. Among them, voice control can recognize at a long distance and has excellent anti-noise performance, that is, it can easily and accurately control the home when the voice is low or noisy. Internet of Things control means that no matter where the device is, as long as it is connected to the WiFi network, it can use mobile phone applications or other terminal devices to realize remote control of home devices and check the usage. In addition, the system is equipped with security function, which can monitor and alarm toxic gas leakage, fire and illegal invasion. The system is also equipped with face recognition function, which can be reconstructed, extended and transplanted very easily, such as the exhibition hall control system, the company's internal control system, the campus control system, and has a wide range of applications. The face recognition function is developed using k210 based on RISV-C architecture and OV2640 camera with low cost. The principle of face recognition is to train the face model through yolo2 model, then compare the real-time images arranged by the camera with the 196-dimensional feature values of the face to recognize the face. Finally, identify whether the current face is the entered face by detecting the five-point key points of the face. In addition, the system is economical and efficient, and can carry out human-computer interaction under specific functional scenarios in the future, including 1. Intelligent control: voice and Internet of Things can help housing owners to conveniently control their homes, check the usage of their homes and various parameters of their homes; 2. Access control system for smart homes: face recognition can replace traditional access control cards or passwords to provide a safer and more convenient access control system. Only need to scan the face to achieve authentication; 3 security monitoring: face recognition can be used to monitor the system, open the protection mode, if the home to identify the unknown person, will remind the owner.
