【摘要】：隨著我國社會經(jīng)濟(jì)的快速發(fā)展,室內(nèi)外大空間、大曠場火災(zāi)消防要求越來越高,現(xiàn)有的消防裝備已經(jīng)無法滿足性能要求。自動跟蹤定位射流消防炮系統(tǒng)能夠快速高效進(jìn)行滅火,將火災(zāi)遏制在萌芽階段,防止火災(zāi)蔓延。因此在室內(nèi)外大空間、大曠場消防滅火中發(fā)揮的作用越來越大。具有自動跟蹤定位功能的消防炮系統(tǒng)能夠主動對火災(zāi)進(jìn)行監(jiān)測、自動定位火源位置、自動噴射滅火劑進(jìn)行滅火,從而保證人員和財(cái)產(chǎn)的安全。目前我國自動跟蹤定位射流消防炮系統(tǒng)的研制還處于借鑒模仿階段,設(shè)計(jì)方法相對比較落后,設(shè)計(jì)規(guī)范也不夠完善,設(shè)計(jì)成本居高不下,設(shè)計(jì)周期比較長,與國外相比,設(shè)計(jì)的自動跟蹤定位射流消防炮系統(tǒng)性能不足,這將制約我國經(jīng)濟(jì)社會的發(fā)展。因此,對動跟蹤定位射流消防炮系統(tǒng)的研究、設(shè)計(jì)、開發(fā)具有非常重要的社會價值和工程意義。論文的主要研究內(nèi)容如下:1、依據(jù)GB 25204-2010《自動跟蹤定位射流滅火系統(tǒng)技術(shù)規(guī)范》中的設(shè)計(jì)要求,對自動跟蹤定位射流消防炮系統(tǒng)進(jìn)行總體設(shè)計(jì),整個系統(tǒng)主要是由前端火災(zāi)探測感知器、控制器、水平定位儀、垂直定位儀以及相應(yīng)驅(qū)動器組成。重點(diǎn)對比了雙波段火焰探測器和三波段火焰探測器作為自動跟蹤定位射流消防炮系統(tǒng)的前級探測感知器裝置的優(yōu)缺點(diǎn),由于雙波段火焰探測器作為自動跟蹤定位射流消防炮系統(tǒng)的前級探測感知器存在探測距離近、誤報率高,因此選擇三波段火焰探測器作為自動自動跟蹤定位射流消防炮系統(tǒng)的前級探測感知器裝置。2、根據(jù)自動跟蹤定位射流消防炮系統(tǒng)的總體設(shè)計(jì)要求,對其中的前端火災(zāi)探測感知器、控制器、水平定位儀、垂直定位儀部分提出了硬件電路設(shè)計(jì)方案,利用Altium Designer15.0軟件設(shè)計(jì)硬件電路,包括單片機(jī)控制電路、紅外火焰?zhèn)鞲衅餍盘栒{(diào)理電路、電源電路、電機(jī)驅(qū)動電路、JTAG電路。3、對自動跟蹤定位射流消防炮系統(tǒng)軟件模塊進(jìn)行了設(shè)計(jì),軟件模塊部分主要包括一級檢測模塊、水平驅(qū)動模塊、二級檢測模塊、水平定位模塊、垂直驅(qū)動模塊、三級檢測模塊、垂直定位模塊、定位模塊以及主控制系統(tǒng)模塊。4、根據(jù)自動跟蹤定位射流消防炮系統(tǒng)的主要設(shè)計(jì)要求及性能指標(biāo),設(shè)計(jì)了系統(tǒng)的機(jī)械結(jié)構(gòu)。該系統(tǒng)采用蝸輪蝸桿傳動作為驅(qū)動器與炮體的動力傳遞方式,對主要結(jié)構(gòu)部件蝸輪、蝸桿進(jìn)行了設(shè)計(jì)計(jì)算,并對壓力水管壁的強(qiáng)度以及壓力水管拉伸強(qiáng)度進(jìn)行了校核計(jì)算,壓力水管壁徑向應(yīng)力和周向應(yīng)力分別為56kg/cm2和520kg/cm2均小于不銹鋼水管壁的許用應(yīng)力1733.3kg/cm2;壓力水管拉伸的最大拉伸應(yīng)力為56kg/cm2小于不銹鋼水管壁的許用應(yīng)力1733.3kg/cm2。利用Pro/E軟件對主要結(jié)構(gòu)部件蝸輪蝸桿進(jìn)行了實(shí)體建模并對整個系統(tǒng)結(jié)構(gòu)進(jìn)行虛擬裝配。5、對自動跟蹤定位消防炮系統(tǒng)水流的軌跡曲線建立了數(shù)學(xué)模型,建立了水流的軌跡方程,推導(dǎo)了俯仰角和射程的關(guān)系方程。采用MATLAB軟件建模仿真模擬水流的軌跡,重點(diǎn)研究在工作壓力p=0.8MPa,流量分別為q=20L/s、30L/s、40L/s,安裝高度分別為H=10m、15m、20m,噴頭直徑分別為d=24.3mm、29.7mm、34.3mm不同的工藝參數(shù)情況下,射程與俯仰角的關(guān)系軌跡模擬圖和水流運(yùn)動軌跡模擬圖,并且建立了數(shù)據(jù)庫�；緷M足設(shè)計(jì)要求中對額定射程的設(shè)計(jì)要求。6、對自動跟蹤定位射流消防炮系統(tǒng)的硬件電路和系統(tǒng)軟件進(jìn)行了調(diào)試,紅外火焰?zhèn)鞲衅餍盘栒{(diào)理電路輸出電壓范圍在780mV-2.10V之間,可以被微控制器ADC模塊采集,采用J-Link+MDK組合的方法在線調(diào)試程序。
