Abstract: In response to the fire safety hazards, information management and maintenance issues in urban building fire protection systems, this article focuses on the CHV32F103 chip and develops fire protection equipment such as a fire fan status information collector and a wind system status information collector. A remote smoke control and monitoring system based on the Internet of Things is proposed. The system consists of a remote control center and on?site monitoring equipment. Its main purpose is to remotely monitor urban building fire protection facilities and analyze and process real-time collected various fault and alarm information. On-site monitoring equipment sends real-time fire alarm signals, smoke exhaust valve action status, and smoke exhaust fan operation status information to the remote control center through Internet of Things communication networks such as NB IoT, ensuring accurate judgment in the event of a fire, achieving remote monitoring and management of the smoke exhaust system.

Key words: Internet of Things, building fire protection, remote monitoring
