多传感器火灾报警系统设计
摘要:从1847年世界上第一台火灾报警装置出现以来,随着公共消防意识的提高与传感器技术的进步,火灾检测的特征量与界定阈值等问题已经基本解决,但是现有的研究在很大程度上并没有解决系统适应性与准确性的矛盾。火灾报警系统的课题研究,对于开发出优秀的火灾报警系统具有重要意义。
本文首先简单介绍了火灾对人类生活的影响并介绍了当今世界火灾报警系统的发展情况;然后,介绍了一种多传感器火灾报警系统的设计,讲解了火灾报警系统的软件功能设计并给出了系统与各个功能模块的程序流程图;之后详细讲解了系统的各功能模块硬件及软件设计,其中硬件设计的最后部分还论述了提高系统抗干扰能力与可靠性的一些方法,并对系统的可扩展性做了简单介绍,软件设计包括针对单片机和传感器的数据采集与数据模糊处理、系统检测与报警程序的设计;之后对硬件进行了简单的调试,对调试结果进行了一些分析;最后,文章对整个设计进行了概括性总结。
本文的重点是系统的硬件以及模糊判断的算法设计,其中详细介绍并论述了系统所需要实现的功能以及各个模块的设计,整个报警系统主要完成采集传感器数据、处理信息并做出判断等功能。
最后的实验结果表明,该设计能够有效解决灵敏度与报警准确率之间的矛盾,能够达到预期的效果。本设计具有高可靠性低误报率等特点,有一定的实用价值。

Design of multi-sensors fire alarm system
Abstract: Fire is mon and high-onset disaster. As the fire itself is highly destructive, it usually causes a lost of life and property. This article describes the affection of fire on human life and introduces the development of fire alarm systems today in world at first; then, it introduces a design of multi-sensor fire alarm system, explains amply about the hardware and software design of each module in system; besides, we did simple hardware debugging, as well as some analysis of the results of the debugging; at last, the article sums up the entire design in general. This article focuses on hardware design and fuzzy judgment algorithm design, which describes and discusses amply the design and achievement of every function the system needs. The alarm system is designed for sensor data acquisition, information processing, making judgments and so on. The last part of the hardware design is also discussed some ways to improve anti-jamming capability and reliability, and gives a brief introduction of the system's extendibility. Software design includes the design of MCU and sensors data acquisition programs, data fuzzy processing programs, system check & alarm programs, and pletes a fire alarm system software functiona
