To meet the requirements of high-precision and full coverage nuclear radiation monitoring,this paper designs a comprehensive nuclear radiation automatic monitoring system based on the Local Outlier Factor(LOF)algorithm.Firstly,based on the specific situation,arrange automatic nuclear radiation monitoring stations,obtain real-time nuclear radiation monitoring data,and transmit it to the server through wireless communication network.Use transmission encryption technology to ensure the security and reliability of the data transmission process;Then,by introducing the LOF algorithm to effectively identify invalid monitoring outliers caused by sensor faults or equipment defects in the monitoring data,the invalid values will not be included in the data statistics;Finally,the effective real-time monitoring data will be transmitted to the monitoring command center.The test results of the system trial operation show that the system can effectively monitor and identify invalid data caused by various hardware failures with high reliability in real-time.The accuracy of invalid data judgment exceeds 95％,improving the stability and reliability of automatic monitoring of nuclear radiation environment,effectively preventing the harm caused by nuclear radiation,and providing reference for promoting sustainable development of ecosystems.
