Design of High Concurrent Communication Server of Elevator Remote Monitoring System

Abstract

Abstract: Since the remote communication server needs to parallelly handle a large number of datagrams with different levels,by using Java NIO,batch data processing,database connection pool and java synchronization,a high concurrency UDP communication server model was proposed.The receiving and sending of datagrams,data acquisition and storage were completed in detail,and a multi-queue thread pool was designed with dynamic priority.The simulation results show that the performance of multi-queue thread pool increases by 15% to 21.58% than the traditional thread pool The practical application effect of the system in Shenyang bluelight group shows that the server model is stable to work for large-scale underlying communication of multi-priority task and has very good generality.
