Aerospace TT&C Equipment Monitoring And Control System Based On Multi-living Agent

Information system, the production of human technology progress, is used for obtaining, processing, storing and distributing information. Information system develops from electronic data processing system, to information management system, and recently to decision support system, which is a complex trend. According to this trend, the information system will contain physical object, named Cyber Physical System(CPS). The physical objects in CPS have more intelligent because of calculation units embedded and comprise system by self organization. They can adjust their behaviors according to inner status and external environment.We can analysis TT&C's trend combining information system and TT&C's characters. But in the early development period of space industry, our country applied the architecture of chimneys commonly, which hinder the development of TT&C career. Due to TT&C system is a huge and complex system, it's difficult to research the whole system. According to actual situation and existing conditions, this paper selects equipment monitor system to analysis and propose solutions. Because this system is an important part in TT&C system and also applies the architecture of chimneys. Analysis of it is useful to solve whole system's problem.During the development of TT&C system, equipment and software was produced by different factories. Because of different protocols and data format, it's difficult to monitor and control these equipment uniformly. The only way is to make operators on duty to monitor the screen day and night. But from recent years, the number of orbiting spacecraft and TT&C task are increasing rapidly. This architecture is not suitable for future. On the other hand, when a new equipment enters the system, people need develop new client software, which cost a lot.For these problems are caused by chimneys architecture, we need to propose a new one. The new architecture can consider a system as whole, unify the data format, enhance resource utilization and avoid redundant construction. And most importantly, the new architecture can make it easy to expand system. Solving problems is not enough, and this architecture must keep up with trend, demanding consideration of self organization anddynamic structure. In order to achieve this goal, this paper proposes living oriented architecture(LOA) basing on multi-living agent theory(MLA).MLA theory is the theoretical basis of LOA and proposed by Academician Wang Yue to solve a problem that it's difficult to apply current complex system theories to engineering. He built this theory basing on object's core mechanism and system's law of motion combined with his rich experience in engineering to analysis and construct complex information system. This theory combines self organization and living, which means the ability to complete certain task or, to put up living self organization and divides a complex system into many living agent. MLA theory also puts up a 4-level mechanism to maintain system's living level.According to MLA theory, LOA theory changes the traditional method of designing a system. LOA considers more about system's core mechanism rather than structure, and regards a system changing over time as a dynamic system. According to the concept of living self organization in MLA theory, LOA concentrates on designing how an agent reacts to different situation. The goal of designing system is improving and maintaining system's live degree. LOA also proposes three principles of designing architecture and seven specifications of designing agents. In this way, we can solve above problems and stand with trend.In the process of using LOA to design a TT&C equipment monitoring and control system basing on MLA theory, this paper proposes an innovative method of applying fuzzy mathematics in calculation of living degree. In the period of simulation, this paper uses JADE to simulate main function of this system because JADE's supports agent program strongly.
