多传感器火灾报警系统的设计 [摘要] 本次毕业设计进行了多传感器火灾报警系统的设计，解决了目前单一的普通类型的火灾探测报警器漏报及误报等问题。火灾报警系统由火灾探测器、单片机、报警装置及具有其他辅助功能的装置组成。在该系统中,多传感器将火灾发生期间所产生的烟、温、气体等信号，连同外界相关的环境参数一起传送给单片机。单片机再根据获取的数据，利用多传感器数据融合技术来判断火灾是否存在。本次设计由于时间不足和缺乏经验等诸多原因，还存在气敏传感器的标定及多传感器数据融合方面等一些需要改进和提高的地方。 [关键词] 多传感器，火灾报警系统，单片机，数据融合， The Design of Multi-sensor Fire Alarm System Zhao Fang （Grade06,Class01,Testing and Monitoring Technology and Instrumentation，Mechanic School，Shaanxi University of Technology，Hanzhong 723003，Shaanxi） tutor: Chen Yingshu Abstract: The content of this graduation project is a multi-sensor fire alarm system. Currently it solves some issues about misstatement, omission and so on in the single and common types of fire detection alarm. The fire alarm system is composed by Single-Chip Microcomputer, fire detectors, alarm device and other device of auxiliary functions. In this system, the signals of the smoke, temperature, gas, which come from multi-sensor during the fire arising, together with the relevant environmental parameters send to Microcomputer (MCU). According to the alarm data, SCM uses the technology of multi-sensor data fusion to judge whether the fire. Because of insufficient time ，lack of experience and many other reasons, there is calibration of gas sensors, multi-sensor data integration and some place which need to improve and enhance in this design.
