Research on thread scheduling based on thread pool in airport vehicle information system

Abstract

For sake of solving the disadvantages including low task execution efficiency, excessive memory and CPU utilization of in the traditional airport vehicle information system, the common thread pool scheduling in airport information system is taken as an example. Several common Java thread pool principles are studied, the common data communication mechanisms such as TCP and UDP and the indicators such as task consumption time, memory utilization rate and CPU utilization rate are analyzed. By means of comparing the call principle of several common Java thread pool scheduling mechanisms, the principle is practically verified through programming. The results show that CachedThreadPool thread scheduling has better performance for data communication sending task applications. For database read-write task applications, FixedThreadPool thread scheduling has better performance. Aiming at different thread pool scheduling mechanisms for different application scenarios, task execution can be guaranteed with less task consumption time, lower memory utilization rate and lower CPU utilization rate in airport vehicle information system.
