摘 要
随着纺织产业的快速发展，纺织仓库的安全监测变得尤为重要。针对纺织仓库可能存在的火灾、烟雾、可燃气体泄露等安全隐患，提出了一种基于STM32的纺织仓库防火控制系统设计。
系统采用STM32F103C8T6单片机作为主控芯片，通过火焰传感器检测是否发生明火，一旦检测到明火，系统立即通过继电器控制水泵进行灭火，并启动声光报警；通过MQ-2烟雾传感器监测仓库内的烟雾浓度，当烟雾浓度超过预设阈值时，系统控制风扇通风，并触发声光报警；通过MQ-5可燃气体传感器监测仓库内的可燃气体浓度，一旦浓度超标，控制风扇通风并报警；通过DS18B20温度传感器实时监测仓库温度，当温度超过设定值时，也采取通风并报警的措施；通过人体热释电模块用于监测监控区域是否有人员闯入，当有人闯入且系统处于布防状态时，立即触发声光警报。此外，系统还具备通过按键设置各监测参数的阈值、手动控制水泵、风扇以及布防撤防的功能。
测试表明，该系统运行稳定，能够实时监测纺织仓库内的多种安全隐患，并采取相应的应急措施，有效提高了仓库的防火安全性能。为纺织产业的安全生产提供了有力保障。

With the rapid development of the textile industry, the safety monitoring of textile warehouses has become particularly important. A fire control system design for textile warehouses based on STM32 is proposed to address potential safety hazards such as fire, smoke, and combustible gas leaks.
The system uses STM32F103C8T6 microcontroller as the main control chip, and detects whether there is an open flame through a flame sensor. Once an open flame is detected, the system immediately controls the water pump through a relay to extinguish the fire and starts an audible and visual alarm; Monitor the smoke concentration in the warehouse through the MQ-2 smoke sensor. When the smoke concentration exceeds the preset threshold, the system controls the fan ventilation and triggers an audible and visual alarm; Monitor the concentration of combustible gases in the warehouse through MQ-5 combustible gas sensors. Once the concentration exceeds the standard, control the fan ventilation and sound an alarm; Real time monitoring of warehouse temperature through DS18B20 temperature sensor. When the temperature exceeds the set value, ventilation and alarm measures are also taken; The human thermoelectric module is used to monitor whether there are personnel entering the monitoring area. When someone enters and the system is in the armed state, an audible and visual alarm is immediately triggered. In addition, the system also has the functions of setting threshold values for various monitoring parameters through buttons, manually controlling water pumps and fans, and deploying and disarming.
Tests have shown that the system runs stably, can monitor various safety hazards in the textile warehouse in real time, and take corresponding emergency measures, effectively improving the fire safety performance of the warehouse. This provides strong guarantees for the safety production of the textile industry.
