【摘要】：随着我国社会经济的快速发展,室内外大空间、大旷场火灾消防要求越来越高,现有的消防装备已经无法满足性能要求。自动跟踪定位射流消防炮系统能够快速高效进行灭火,将火灾遏制在萌芽阶段,防止火灾蔓延。因此在室内外大空间、大旷场消防灭火中发挥的作用越来越大。具有自动跟踪定位功能的消防炮系统能够主动对火灾进行监测、自动定位火源位置、自动喷射灭火剂进行灭火,从而保证人员和财产的安全。目前我国自动跟踪定位射流消防炮系统的研制还处于借鉴模仿阶段,设计方法相对比较落后,设计规范也不够完善,设计成本居高不下,设计周期比较长,与国外相比,设计的自动跟踪定位射流消防炮系统性能不足,这将制约我国经济社会的发展。因此,对动跟踪定位射流消防炮系统的研究、设计、开发具有非常重要的社会价值和工程意义。论文的主要研究内容如下:1、依据GB 25204-2010《自动跟踪定位射流灭火系统技术规范》中的设计要求,对自动跟踪定位射流消防炮系统进行总体设计,整个系统主要是由前端火灾探测感知器、控制器、水平定位仪、垂直定位仪以及相应驱动器组成。重点对比了双波段火焰探测器和三波段火焰探测器作为自动跟踪定位射流消防炮系统的前级探测感知器装置的优缺点,由于双波段火焰探测器作为自动跟踪定位射流消防炮系统的前级探测感知器存在探测距离近、误报率高,因此选择三波段火焰探测器作为自动自动跟踪定位射流消防炮系统的前级探测感知器装置。2、根据自动跟踪定位射流消防炮系统的总体设计要求,对其中的前端火灾探测感知器、控制器、水平定位仪、垂直定位仪部分提出了硬件电路设计方案,利用Altium Designer15.0软件设计硬件电路,包括单片机控制电路、红外火焰传感器信号调理电路、电源电路、电机驱动电路、JTAG电路。3、对自动跟踪定位射流消防炮系统软件模块进行了设计,软件模块部分主要包括一级检测模块、水平驱动模块、二级检测模块、水平定位模块、垂直驱动模块、三级检测模块、垂直定位模块、定位模块以及主控制系统模块。4、根据自动跟踪定位射流消防炮系统的主要设计要求及性能指标,设计了系统的机械结构。该系统采用蜗轮蜗杆传动作为驱动器与炮体的动力传递方式,对主要结构部件蜗轮、蜗杆进行了设计计算,并对压力水管壁的强度以及压力水管拉伸强度进行了校核计算,压力水管壁径向应力和周向应力分别为56kg/cm2和520kg/cm2均小于不锈钢水管壁的许用应力1733.3kg/cm2;压力水管拉伸的最大拉伸应力为56kg/cm2小于不锈钢水管壁的许用应力1733.3kg/cm2。利用Pro/E软件对主要结构部件蜗轮蜗杆进行了实体建模并对整个系统结构进行虚拟装配。5、对自动跟踪定位消防炮系统水流的轨迹曲线建立了数学模型,建立了水流的轨迹方程,推导了俯仰角和射程的关系方程。采用MATLAB软件建模仿真模拟水流的轨迹,重点研究在工作压力p=0.8MPa,流量分别为q=20L/s、30L/s、40L/s,安装高度分别为H=10m、15m、20m,喷头直径分别为d=24.3mm、29.7mm、34.3mm不同的工艺参数情况下,射程与俯仰角的关系轨迹模拟图和水流运动轨迹模拟图,并且建立了数据库。基本满足设计要求中对额定射程的设计要求。6、对自动跟踪定位射流消防炮系统的硬件电路和系统软件进行了调试,红外火焰传感器信号调理电路输出电压范围在780mV-2.10V之间,可以被微控制器ADC模块采集,采用J-Link+MDK组合的方法在线调试程序。
