摘　　要：流程生产安全监测是其安全风险控制和事故预防的主要技术手段,而监测数据是安全管控与决策的重要依据。现有的安全监测组网架构中,传感器节点多、数据量大,使得无线传感网络的信道负载较重,容易出现数据时延、丢失等问题,影响安全管控决策的及时性和准确性。为此,针对典型流程生产场景的安全风险因素,明确其传感器部署方案及无线传感网络数据传输架构,提出基于主从机分流的安全监测数据流调度机制和方法,采用数据的拥堵指数与频率异常指数作为数据流性能评估的主要指标。以化工聚合反应釜为工程场景,检验了当反应釜数量和安全监测数据量增加时启动从机为主机分担数据流量后的性能改进,有利于保障安全监测数据有序传输和风险控制的有效性。Process production safety monitoring is the main technical method for safety risk control and accident prevention,and data is a significant basis for safety control and decision-making.In the existing security monitoring network,there are many sensor nodes and large amounts of data,which cause heavy channel load in the wireless sensor network.This often leads to issues such as data latency and loss,which affects the timeliness and accuracy of safety control decisions.Therefore,the security risk factors of typical process production scenarios were focused on.Based on this,the sensor deployment plan and wireless sensor network data transmission architecture were clarified,a security monitoring data flow scheduling method based on superior-subordinate server was proposed,and the data stream congestion index and abnormal data packet frequency index were used as the main indicators of data flow performance evaluation.Subsequently,the chemical polymerization reactor were taken as an engineering scenario,the performance improvement was examined after the subordinate server was initiated to share the data flow for the superior server.Through the comprehensive study of channel load balancing,the method of superior-subordinate server is benefit to ensure the effectiveness of orderly transmission of safety monitoring data and risk control.
