基于Web3D構(gòu)建公共消防疏散系統(tǒng)存在許多限制其計算能力的瓶頸。本文集中解決3個關(guān)鍵問題:(1)大型建筑場景數(shù)據(jù)量大,難以通過互聯(lián)網(wǎng)傳輸并在網(wǎng)絡終端設(shè)備實現(xiàn)可視化;(2)原始火災動態(tài)模擬器煙氣數(shù)據(jù)量大,且實時動態(tài)變化,難以通過互聯(lián)網(wǎng)傳輸并在網(wǎng)絡終端設(shè)備實現(xiàn)可視化;(3)為公眾提供的智能消防疏散系統(tǒng)往往難以兼顧準確性和實時性。針對以上問題,本文提出3個解決方案:(1)將大型場景模型簡化為輕量型場景模型;(2)將動態(tài)煙霧簡化為輕量級煙霧模型;(3)利用場景模型和煙霧數(shù)據(jù)建立動態(tài)障礙物圖,規(guī)劃最優(yōu)疏散路徑。本文提出一種基于蟻群優(yōu)化算法(RFES-ACO)的實時消防疏散系統(tǒng),該算法基于動態(tài)信息素重用。仿真結(jié)果表明,公眾可在移動Web3D設(shè)備上實時、順暢地進行消防疏散演練的交互和體驗。最后,與leader-follower算法和隨機算法的對比實驗,證明了實時消防疏散系統(tǒng)(RFES)的高效性,其疏散率優(yōu)于其它兩種算法。
