摘　　要：烟花在存储过程中安全问题尤为重要.对烟花温、湿度进行实时监测,须设置报警装置.当超过上限时,能进行声光报警,并将数据传到服务器进行相应处理.通过STM32控制器、nRF2401无线通信模块、LED灯以及蜂鸣器可以实现上述功能.在STM32中移植μC/OS操作系统,对程序设计采用并行开发模式,简化程序结构,提高系统的实时性.改进μC/OS中的消息邮箱机制,实现数据采集任务与多个报警任务的同步.Fireworks need special caution in the storage process , it needs a real-time monitoring for temperature and humidity , it needs an alarm device , when the data is more than the upper limit , it can alarm by sound and light , and it also can send the data to the server for the corresponding treat-ment.Through STM32 controller, nRF2401 wireless communication module , LED lamp and the buzz-er can realize the system .The program is transplanted μC/OS operating system in STM 32 , designing with the parallel model , it can simplified structure of program , improves the real-time property of the system.The program can synchronize data acquisition task and multiple alarm task by improving the mailbox mechanism in μC/OS.
