【摘要】：社区环境与人们的生活和工作息息相关,尤其是社区安全更是大家关注的重点。进入二十一世纪以来,无线传感技术、通信技术发展迅猛,并且逐渐走进人们的生活,人们对于社区的居住环境也提出了更多的需求。智慧社区的概念就是在这样的需求下产生的,社区不再仅仅是一个群众聚居区,而是一个能为居民提供现代化、智慧化的方便、舒适、安全生活的新管理形态社区。火灾一直威胁着人们的生活环境。近年来,各种家用电器、家用燃气已经与我们的生活深深交织在一起,各种装修材料也被广泛应用。然而,电器老化、燃气泄漏、易燃材料的不正当安置都成为了引发社区火灾的重要原因：并且,火灾一旦发生,现场的环境十分混乱,人员疏散缓慢、物资撤离低效,会让火灾造成更大的损失。现有火灾防控系统的智能化程度不足,人力维护困难大、成本高,而火灾一旦发生,现场的调度与救援工作又十分混乱。鉴于此,本文研究的主要内容是应用于智慧社区管理系统中的基于ZigBee技术的火灾防控子系统。ZigBee具有成本低、功耗小、体积小、组网方便等特点,这些特点十分适合社区无线传感网的建立。在火灾防控系统系统的研究开发中,本文主要做了以下工作：(1)经过学习,了解了现在信息技术的发展状况,分析了未来社区的发展趋势。通过分析现有社区防火技术的不足,提出了利用ZigBee技术对社区环境进行监测,解决社区火灾防控中的问题；(2)研究学习了ZigBee技术的发展现状,通过与其它多种无线传感技术比较,指出ZigBee技术上的优势更适合应用于智慧社区火灾防控系统；(3)根据智慧社区在建设中的应用需求,整理出ZigBee技术在社区火灾防控中的各项功能模块,对ZigBee节点做了硬件设计,并根据社区环境特点对下位机和上位机算法做出相应改进；(4)对ZigBee模块的硬件功能和软件功能做出相应的测试,并分析了测试结果,提出未来需要改进的地方。
[Abstract]:Community environment is closely related to people's life and work, especially community safety.Since 21 century, wireless sensing technology and communication technology have developed rapidly, and come into people's life gradually, people also put forward more demands for the living environment of the community.The concept of intelligent community comes into being under such a demand. The community is no longer just a mass community, but a new management community which can provide the residents with modern, intelligent convenience, comfortable and safe life.Fire has always threatened people's living environment.In recent years, all kinds of household appliances and household gas have been deeply intertwined with our lives, and various decoration materials have also been widely used.However, the aging of electrical appliances, gas leakage and improper placement of flammable materials have all become important causes of community fires: in the event of a fire, the environment on the scene is very chaotic, the evacuation of personnel is slow, and the evacuation of materials is inefficient.The fire will cause more damage.The existing fire prevention and control system is not intelligent enough, the manpower maintenance is difficult, the cost is high, and once the fire occurs, the field dispatching and rescue work is very chaotic.In view of this, the main content of this paper is that the fire prevention and control subsystem. ZigBee, which is applied to the intelligent community management system based on ZigBee technology, has the characteristics of low cost, small power consumption, small volume, convenient networking and so on.These characteristics are very suitable for the establishment of community wireless sensor network.In the research and development of fire prevention and control system, this paper mainly does the following work: 1) after studying, we understand the development situation of information technology and analyze the development trend of future community.Based on the analysis of the deficiency of the existing community fire prevention technology, this paper puts forward to use ZigBee technology to monitor the community environment and solve the problems in community fire prevention and control. It studies the development status of ZigBee technology and compares it with other kinds of wireless sensing technology.It is pointed out that the advantages of ZigBee technology are more suitable for application in intelligent community fire prevention and control system. According to the application demand of intelligent community in the construction, the function modules of ZigBee technology in community fire prevention and control are sorted out, and the hardware design of ZigBee node is made.According to the characteristics of community environment, the algorithm of lower computer and upper computer is improved accordingly. (4) the hardware function and software function of ZigBee module are tested, and the test results are analyzed, and some improvements in the future are put forward.
