基于 STM32的无线火灾定位报警系统设计

摘要

A wireless location of fire alarm system,based on STM32,is designed.STM32F103VET6 is used as the main controller of System to manage the scene detection and alarm in time.GPS module, obtaining positioning data,is used to determine the construction location information of the fire which is processed and sent by GPRS wireless transmission module,and received and displayed by the software. Combining with a weighted decision tree algorithm,the alarm condition is judged to prevent false positives.The terminal hardware is composed of the main controller,GPRS module,GPS module,the temperature and smoke sensor module and alarm module.The experiments show that the system,with the stable performance and meeting the design requirements,is applicable to wireless positioning fire detection and alarm.%设计了一种基于 STM32的无线定位火灾报警系统。系统以 STM32F103VET6为主控制器完成现场检测和现场报警。GPS 模块来获取定位数据确定火灾发生的建筑位置信息，经处理器处理后由 GPRS 无线传输模块发送位置信息，由上位 PC 接收位置信息并显示位置数据；并结合一个加权决策树算法判断报警条件防止误报。终端硬件包括主控制器、GPRS 模块、GPS 模块、温度烟雾传感器模块，报警模块；数据通过无线网络传给上位机 PC 并以上位软件入库显示。实验得到良好的效果，性能稳定，满足设计要求，适用于无线火灾定位报警，满足实际需求。
