Abstract
With the rapid development of information technology, the remote control has become an important means to improve production efficiency and intelligence level. In this paper, an embedded remote control system based on NBIoT technology is designed and produced. Based on STM32F427 as the control core, the system can collect the current and voltage of each branch and perform data analysis, data processing, and branch on-off control. It connects multiple smoke sensors to realize the fire warning function. Data transmission is realized through NBIoT technology and the OneNet platform, and users can realize remote control through APP. Multiple built-in communication interfaces can be extended for different scenarios. It has a good effect on the test and can meet the requirements of remote control. It has high application value in industrial control, smart city, and other fields.
