摘要
为解决无人机在山区输电线路周边火灾隐患的巡检和早期灭火作业中存在的耗费时间长、工作效率低等问题,合并重组优化现有无人机巡检和灭火流程步骤。首先,在现有的无人机巡视和灭火流程的研究基础上,基于流程程序分析法和Petri网模型法,分析无人机巡视和灭火流程的2个步骤,得到对应工作流程,利用相关矩阵和不变量分析方法检验该模型,以确保其适用性;然后,基于取消、合并、调整顺序、简化(ECRS)原则,统一2个独立步骤,合并重复步骤,得出最终优化后的流程方案;最后,通过相同案例进行仿真模拟,分析并计算整合优化前后模型的差异。结果表明:基于Petri网优化后的方案能大幅提高灭火无人机收到火源坐标位置信息后的快速响应能力,减少重复作业流程,降低不必要的时间消耗;相较于传统作业方案完成全部流程的时间,优化后的流程方案作业时间减少39.1%,搬运距离减少50%。
Unmanned aerial vehicles(UAVs)face long time consumption and low work efficiency in inspecting fire hazards around transmission lines in mountainous areas and performing early fire extinguishing operations.In order to solve these problems,the existing UAV inspection and fire extinguishing processes were merged and reorganized.Firstly,based on the existing research on UAV inspection and fire extinguishing processes,process program analysis and Petri net model method were adopted,and the processes of UAV inspection and fire extinguishing were analyzed to obtain the corresponding operation process.The correlation matrix and invariant analysis method were used to test the model to ensure its applicability.Then,the two independent steps were unified,and the repeated steps were merged based on the principle of eliminate,combine,rearrange,and simplify(ECRS).The final optimized process scheme was thus obtained.Finally,through the simulation of the same case,the difference between the model before and after the integration optimization was analyzed and calculated.The results show that the optimized scheme based on Petri net can greatly improve the rapid response ability of UAVs for fire extinguishing after receiving the fire source coordinate position information and reduce the repeated operation process and unnecessary time consumption.Compared with that of the traditional operation scheme,the operation time of the optimized process scheme is reduced by 39.1%,and the handling distance is reduced by 50%.
