摘要: 针对智能矿用精确人员定位系统存在误判井下人员遇险,造成救援资源浪费的问题,提出将层次分析法应用于智能矿用人员精确定位系统应急处理机制中。传统层次分析法的判断矩阵一旦设置后,无法实时响应影响因素的变化,当影响因素数值发生改变后,需要重新设置判断矩阵才能获得正确的决策方案。针对该问题,对层次分析法进行改进,提出根据传感器的实时数据对层次分析法的判断矩阵进行调整,以提高报警准确率。当精确人员定位系统的管理服务器收到井下某人员标签上报的报警信息后,采用1—9标度方法对该人员所处位置的各类传感器数据及由人员标签上传的生命特征传感器数据进行标度,根据传感器数据的标度值实时调整各个指标层-决策层判断矩阵的参数值,采用层次分析法计算决策层权重值,根据权重值判断报警信息的真实性。仿真结果表明,精确人员定位系统应急处理机制采用能实时调整判断矩阵参数的改进层次分析法后,可有效判断出报警信息的真实性,排除无效报警信息,从而提高了应急处理机制的报警准确率。Abstract: In order to solve the problem of misjudgment of underground personnel in distress in the intelligent mining precise personnel positioning system, resulting in a waste of rescue resources, this paper proposes to apply the analytic hierarchy process to the emergency treatment mechanism of the intelligent mining personnel precise positioning system. Once the judgment matrix of the traditional analytic hierarchy process method is set, it cannot respond to the changes of the influencing factors in real time. When the value of the influencing factor changes, the judgment matrix needs to be reset to obtain the correct decision scheme. In order to solve this problem, the analytic hierarchy process method is improved and the judgment matrix of the analytic hierarchy process method is proposed to be adjusted according to the real-time data of the sensors to improve the alarm accuracy. When the management server of the precise personnel positioning system receives the alarm information reported by a person tag in the mine, the method uses the 1-9 scale method to mark the various sensor data of the personnel's position and the sensor data of vital characteristics uploaded by the tag. According to the scale value of the sensor data, the parameter values of the judgment matrix of each index layer-decision layer are adjusted in real time, and the weight value of the decision layer is calculated by the analytic hierarchy process, and the authenticity of the alarm information is judged according to the weight values. The simulation results show that after the emergency treatment mechanism of the precise personnel positioning system adopts the improved analytic hierarchy process that can adjust the parameters of the judgment matrix in real time, the authenticity of the alarm information can be judged effectively, invalid alarm information is eliminated, and the alarm accuracy of the emergency treatment mechanism is improved.
