摘要

In order to improve the reliability and accuracy of the oil rig safety monitoring system,a safety information fusion model of drilling rig based on D-S evidence theory is proposed.Firstly,the operation state of the oil rig is modeled and mathematically processed,and a multi-source in formation fusion model is established.Secondly,according to the result of fusion information and expert decision rule,the D-S evidence theory information fusion algorithm is used to judge the safety status of drilling rig equipment in real time.Finally,the simulation model is established by the actual mine data,and the feasibility and validity of the information fusion model are verified.%为提高石油钻机安全监控系统的可靠性和准确性,提出了一种基于D-S证据理论的钻机安全信息融合模型.首先对石油钻机的多种运行状态进行模型化和数字化处理,并建立多源信息融合模型.其次根据融合信息结果和专家决策规则,利用D-S证据理论信息融合算法对钻机设备的安全状态进行实时判断.最后通过实际油井数据建立仿真算例,验证了该信息融合模型的可行性和有效性.
