Design and Fabrication of Clock Synchronization System Based on Single Chip Microcomputer

The introduction of the Internet of Things system facilitates the involvement of traditional industries, but the problem of time synchronization between the upper computer system and the lower computer system of the Internet of Things may be worth studying and solving. This paper mainly introduces a complete set of solutions for the Internet of Things clock system. The hardware system introduces the clock display and storage system based on a 51-core microcontroller; the software system introduces the Bluetooth communication data docking system for Android.The system solution uses the SCM interrupt system to send Bluetooth data. The data contains an accurate communication protocol, completes the checking of data header, data body, and data CRC16 data. The accurate synchronization of the clock system is accomplished through high-speed data communication.
