In order to solve the problem of insufficient coordination in the traditional field security system due to the lack of extensive interconnection and interoperation, the architecture of the intelligent field security system for military airports was established. This paper introduces the concepts of cloud computing and cyber-physical systems (CPS) into the field service security system, studies the architecture of the intelligent field service security system, analyzes the basic connotation of the intelligent field service security system and the construction requirements of the system architecture, and explains the functions and characteristics of each level in the architecture. The results show that this architecture has the advantages of powerful information processing capacity, flexible on-demand service mode, efficient collaborative control, and can improve the intelligence and information level of the field service guarantee system.
