"基于AT89C51单片机的矿井环境监测系统设计与实现"

The design of a mining environment monitoring system based on a single-chip microcontroller (MCU) is of great significance for ensuring the safety and efficient production of coal mines, which are a major source of energy in China. The system, which has AT89C51 single-chip microcontroller as its core, consists of control module, information collection module, display module, wireless transmission module, and alarm module. Temperature and humidity sensors, as well as methane concentration sensors, collect information about the underground air quality. The wireless module transmits the collected information to the control center, where the single-chip microcontroller processes and analyzes the data using the display and alarm modules to enable real-time monitoring of the underground environment. This design enables real-time monitoring and wireless transmission of mining environments. The system is characterized by its stable performance, low cost, ease of operation, and strong applicability. Key words: mine monitoring; microcontroller; alarm; wireless transmission.
