Design And Implementation Of A Reconfigurable Integrated Test System

With the rapid development of science and technology and electronic products, in recent 20 years, aerospace technology has been continuously developing and updating at home and abroad, product development time is shortened, update and upgrade speed is improved. The test system developed for specific models in the past has been impossible to meet the test requirements of aerospace equipment which has more complex electronic equipment and the function is becoming more and more complete and highly integrated and can also have better real-time performance. Not only did the platform management subsystem has relationship with other subsystem of unmanned aerial vehicle(UAV) but also directly communicated to ground base station, it is mainly responsible for the data acquisition and indirect operation with other systems, it’s an important part of the UAV system, so it has a very strong engineering significance to research and develop a general integration test system for the management subsystem.This dissertation is based on the design and implementation of the integrated test system, learn about the relevant theoretical knowledge system architecture and key technologies for the research, and this dissertation aim to complete the integrated test system of manage platform.In this dissertation, firstly, introduced the hardware resources and software design of the system, the platform management system of aircraft is a complex system, it’s has a lot of relationship with other subsystems of aircraft. In order to ensure a variety of working conditions in the test, integrated test system needs to provide various types of interface resources in hardware, and to ensure the real-time performance of the system, it is necessary to explain the hardware selection. In addition, to ensure the flexibility of the system, layered and open software architecture is adopted in software design, and modular design is used in the realization of the function of the system. Unified hierarchical design of XML, which ensures the scalability and flexibility of the analytic part of the system.Secondly, the design of the database table about the interface control document(ICD) is described, ICD is the key to the whole system analysis. ICD database is directly connected to test system in the past, in this dissertation, the information related to analysis are extract from ICD and stored in XML document, thus making ICD database separated from test system.Then it explains the realization of each function module in detail, the system module is divided into the real-time function module and the none real-time function module. In the realization of real-time modules, pays attention to the system’s real-time implementation. In the process of data analysis and storage, in order to prevent data from being drowned by uploaded data, making analysis and storage process not perfect, the double ring buffer technology is used. In addition, to making the display interface easily been recognized, it use the graphical control. Because the use of graphical control makes the system appear flash screen problem, using C# double buffering technology to solve this problem.At last, the dissertation puts forward the optimization of the realization of the function, making the comparison of the transmission mode of the network, and puts forward the fast transmission mode among others. Finally, in order to ensure the function and performance of the system, the system’s function modules are been tested and verified.
