为有效进行楼宇火灾预警,及时疏散人员、减少损失,设计基于多传感器的楼宇火灾预警系统.采用多种传感器获得较多的环境信息,通过无线通信技术进行信息的传输,避免了因传输介质连接所引起的弊端,提高了系统的可靠性.各组件之间的配置与控制由单片机完成,在数据处理方面通过设定阈值达到预警目的. In order to effectively carry out building fire early warning, evacuate personnel and reduce losses in time, a multi-sensor building fire early warning system is designed.With a variety of sensors to obtain more environmental information, wireless communication technology to transmit information, to avoid the transmission medium connection Caused by the shortcomings and improve the reliability of the system.Configuration and control between the various components by the MCU to complete, in data processing by setting the threshold to achieve the purpose of early warning.
