摘　　要：在复杂的建筑环境中,当前阈值计算方法对于风险模糊事件监测困难,风险概率阈值计算结果准确度较低。因此,提出建筑环境传感节点监测中的风险概率阈值计算。通过分析传感网络在建筑环境中的监测原理,识别风险因素,计算节点冲突概率,得到风险模糊事件概率,并构建风险概率模型,基于该模型计算监测风险率,求得风险概率阈值。实验结果显示,利用所提方法对传感节点监测中的风险阈值进行计算,可得到较高的计算准确度。In the complex building environment,the current threshold calculation method is difficult to monitor the risk fuzzy events,and the accuracy of the risk probability threshold calculation result is low.Therefore,the calculation of risk probability threshold in the monitoring of building environment sensor nodes is proposed.By analyzing the monitoring principle of the sensor network in the building environment,the risk factors are identified,calculate that collision probability of nodes,the risk fuzzy event probability is obtained,and the risk probability model is constructed.Based on this model,the monitoring risk rate is calculated,and the risk probability threshold is obtained.The experimental results show that the proposed method can be used to calculate the risk threshold in sensor node monitoring,and higher calculation accuracy can be obtained.
