Abstract:Abstract: Smart homes enhance safety, convenience and comfort for modern homes, and the use of smart homes makes life more energy efficient. In response to current needs in people's lives, the quality of indoor environment, home entertainment, intelligent security and so on. The design of this paper is to use the ESP32 MCU as the main control chip, provides a smart home center control system based on Internet of things platform. The user can operate the device through offline voice recognition on the device side, online voice recognition on the WEB side, and WEB interface operation; the operation command of the WEB end is connected to the Internet of Things platform by the network, and then the instruction is sent to the device by the Internet of Things platform,final Completed the goal of smart home data collection and device control. This article introduces the whole scheme design, hardware circuit design, selection and analysis of system function modules and software process design. The operating results and performance analysis of the system under the environment of hardware and software are carried out, the results showed that the system could run steadily and exact, the operation and maintenance is convenient, the system has very high value of industrialization, and reference significance for other smart home.
