【摘要】：虛擬人群仿真技術(shù)當(dāng)前已在高層建筑火災(zāi)、大型體育場(chǎng)館突發(fā)事件、地鐵火災(zāi)等公共安全領(lǐng)域的應(yīng)急撤離仿真中得到廣泛應(yīng)用。然而，由于煤礦井下的特殊環(huán)境，目前井下事故應(yīng)急撤離虛擬人群仿真研究還非常有限。煤礦安全行為學(xué)研究表明，系統(tǒng)地研究井下礦工在煤礦火災(zāi)、瓦斯爆炸等典型事故中的應(yīng)急撤離行為，建立有效的井下事故應(yīng)急撤離仿真模型，不僅對(duì)制定有效的井下事故應(yīng)急預(yù)案具有實(shí)際的指導(dǎo)意義，而且對(duì)提高井下礦工培訓(xùn)水平也有非常重要的現(xiàn)實(shí)意義。然而，傳統(tǒng)系統(tǒng)安全工程方法的實(shí)驗(yàn)環(huán)境難以保證，耗資巨大，又相當(dāng)危險(xiǎn)。 本文結(jié)合當(dāng)前虛擬人群仿真技術(shù)與煤礦井下事故應(yīng)急撤離實(shí)際場(chǎng)景，基于多智能體技術(shù)，研究煤礦井下虛擬人群應(yīng)急撤離行為仿真方法，重點(diǎn)考慮煤礦井下應(yīng)急撤離中不同角色的心理、生理特征，構(gòu)建不同角色虛擬礦工的應(yīng)急決策模型，研究井下虛擬人群應(yīng)急撤離算法及典型事故應(yīng)急撤離虛擬現(xiàn)實(shí)仿真系統(tǒng)，，不僅有利于深入理解井下應(yīng)急撤離中礦工及其組織的行為，為制定更加切實(shí)可行的井下事故應(yīng)急撤離預(yù)案及井下礦工訓(xùn)練方案提供一定的理論及技術(shù)支撐，也有利于當(dāng)前虛擬人群仿真技術(shù)的具體應(yīng)用。主要研究內(nèi)容及成果包括： 1.根據(jù)煤礦井下事故應(yīng)急撤離的特殊環(huán)境，構(gòu)建了基于多智能體的井下虛擬人群應(yīng)急撤離仿真模型。該模型由虛擬人群仿真模塊、幾何場(chǎng)景仿真模塊、場(chǎng)景數(shù)據(jù)庫模塊、人機(jī)交互模塊和事件記錄模塊五部分組成。同時(shí)，研究了井下事故應(yīng)急撤離中的人群行為特征，建立了基于角色的井下應(yīng)急撤離虛擬人群仿真算法，實(shí)現(xiàn)井下事故應(yīng)急撤離中“領(lǐng)導(dǎo)者-跟隨者”的行為仿真。此外，研究了井下典型智能體的構(gòu)建方法，建立了自主虛擬礦工智能體、環(huán)境/設(shè)備類智能體模型。 2.研究了井下應(yīng)急撤離虛擬人群逃生路徑規(guī)劃算法。建立了虛擬礦井的柵格化模型，基于典型的A*算法，實(shí)現(xiàn)了井下應(yīng)急撤離虛擬人群逃生路徑選擇，重點(diǎn)根據(jù)煤礦井下應(yīng)急撤離中不同巷道的通行難易程度及礦工跨越不同障礙的高度信息，建立了考慮勢(shì)能的A*路徑規(guī)劃的啟發(fā)式搜索函數(shù)，使路徑規(guī)劃結(jié)果更符合井下實(shí)際情況。 3.研究了目前虛擬環(huán)境典型的碰撞檢測(cè)算法，基于AABB層次包圍盒模型，建立了虛擬礦井的碰撞檢測(cè)方法。在此基礎(chǔ)上，重點(diǎn)研究了井下應(yīng)急撤離虛擬人群避碰方法，建立了井下虛擬人群典型運(yùn)動(dòng)形式的避碰策略與算法。 4.設(shè)計(jì)、開發(fā)了煤礦井下應(yīng)急撤離虛擬人群仿真系統(tǒng)，實(shí)現(xiàn)了虛擬煤礦井下漫游及典型事故虛擬人群仿真。結(jié)合井下火災(zāi)事故應(yīng)急撤離案例，具體介紹了虛擬人群仿真方法，并針對(duì)不同角色組成的人群場(chǎng)景，仿真了其應(yīng)急撤離過程與實(shí)際效果，初步驗(yàn)證了本文提出的相關(guān)模型與方法。
[Abstract]:Virtual crowd simulation technology has been widely used in the emergency evacuation simulation in the field of public safety, such as high-rise building fire, large-scale stadium emergencies, subway fire and so on. However, due to the special environment of underground coal mine, the simulation of emergency evacuation of underground accidents is still very limited. The study of coal mine safety behavior shows that the emergency evacuation behavior of underground miners in coal mine fire, gas explosion and other typical accidents is systematically studied, and an effective simulation model of underground emergency evacuation is established. It is not only of practical significance to formulate an effective emergency plan for underground accidents, but also of great practical significance to improve the training level of underground miners. However, the experimental environment of traditional system safety engineering methods is difficult to guarantee, expensive and dangerous. Combined with the current virtual crowd simulation technology and the actual scene of underground mine emergency evacuation, based on multi-agent technology, the simulation method of emergency evacuation behavior of virtual crowd in coal mine is studied in this paper. Considering the psychological and physiological characteristics of different roles in underground emergency evacuation, the emergency decision-making model of virtual miners with different roles is constructed, and the emergency evacuation algorithm and virtual reality simulation system of typical accidents emergency evacuation are studied. It is not only beneficial to deeply understand the behavior of miners and their organizations in underground emergency evacuation, but also to provide certain theoretical and technical support for formulating more feasible emergency evacuation plan and training scheme for underground miners. It is also beneficial to the concrete application of virtual crowd simulation technology. The main contents and achievements of the study include: 1. According to the special environment of underground emergency evacuation, the simulation model of underground virtual crowd emergency evacuation based on multi-agent is constructed. The model consists of virtual crowd simulation module, geometric scene simulation module, scene database module, human-computer interaction module and event recording module. At the same time, the characteristics of crowd behavior in underground emergency evacuation are studied, and a role-based virtual crowd simulation algorithm for underground emergency evacuation is established to simulate the behavior of "leader-follower" in downhole emergency evacuation. In addition, the construction method of typical underground agent is studied, and the autonomous virtual miner agent, environment / equipment agent model is established. 2. The algorithm of escape path planning for underground emergency evacuation virtual crowd is studied. The rasterization model of virtual mine is established. Based on the typical A * algorithm, the escape path of emergency evacuation virtual crowd is realized. The heuristic search function of path planning of A * considering potential energy is established according to the information of the difficulty of passing through different roadways and the height of miners crossing different obstacles in emergency evacuation of underground coal mine. Make the path planning results more in line with the actual situation underground. 3. The typical collision detection algorithm in virtual environment is studied. Based on the AABB hierarchy bounding box model, the collision detection method of virtual mine is established. On this basis, the collision avoidance method of underground emergency evacuation virtual crowd is studied, and the collision avoidance strategy and algorithm of typical movement form of underground virtual crowd are established. 4. The virtual crowd simulation system for emergency evacuation of coal mine is designed and developed, and the virtual crowd simulation for underground roaming and typical accidents is realized. Combined with the emergency evacuation case of underground fire accident, the simulation method of virtual crowd is introduced in detail, and the emergency evacuation process and actual effect are simulated according to the crowd scene composed of different roles. The related models and methods proposed in this paper are preliminarily verified.
