摘　　要：本文基于Petri网理论构建了一个全态势感知系统模型,旨在实现对煤矿瓦斯和地质应力灾害的实时预警。首先,本文利用模糊Petri网对事故类型诊断规则进行一个模糊推理,计算出各类事故对应的置信度并生成模糊推理规则。之后,利用P/T系统对传统煤矿瓦斯与地质应力感知系统进行建模,通过深入分析来指出传统系统模型的不足,据此构建了优化后的系统模型。通过计算优化前后模型对事故响应的总置信度,对比得出优化后模型总置信度提高了21.67%。随后,利用PIPEv3.4.0软件对优化前后模型进行了状态空间分析,得到了有界、安全和无死锁的仿真结果,验证了改进前后模型的可行性和可靠性。This study presents a comprehensive situational awareness system model constructed based on Petri net theory,with the objective of achieving real-time early warning for coal mine gas and geological stress disasters.Initially,fuzzy Petri nets are employed to perform fuzzy inference on the diagnostic rules for accident types,thereby calculating the corresponding confidence levels for various accidents and generating fuzzy inference rules.Subsequently,a P/T system is utilized to model the traditional coal mine gas and geological stress perception system.Through in-depth analysis,the deficiencies of the traditional system model are identified,leading to the construction of an optimized system model.By calculating the total confidence level of the system’s response to accidents before and after optimization,it is demonstrated that the total confidence level of the optimized model has increased by 21.67%.Thereafter,the PIPEv3.4.0 software is employed to conduct state space analysis on both the pre-and post-optimized models,yielding simulation results that are bounded,safe,and free of deadlocks,thereby validating the feasibility and reliability of the models both before and after the improvements.
