INTRODUCTION
Different types of aeronautical data were recorded in order to control airborne equipment’s status and improve their performance. Those aeronautical data’s ground afterward applications were realized by many different ground process system [1][2]. However, those ground process system only can process one give type aeronautical data usually, which restrict the synthetic usage of different type aeronautical data. Aeronautical data integrated ground process system focus on synthesis management, transfer, and basic application of airborne recorded data of different hierarchy, different plane type, and different equipment. Server/Client architecture was adopted in the system, and all aeronautical data were stored in the server while users can accomplish different operations to aeronautical data remotely. As a ground application platform of recorded data, aeronautical data integrated ground process system focus on aeronautical data’s integrated management, transfer, and share.
_________________________________________
The system provides new data type’s appending, which ensure extension of record device and plane type. Meanwhile users and client terminal’s increase were realized. Finally, new aeronautical data application’s expending was also carried out.
SYSTEM FUNTIONS
Aeronautical data integrated ground process system was designed to manage and use recorded aeronautical data, its functions include ground data management and data application. In order to manage and use massive airborne recorded data effectively, management of device and users need to be included in system functions. The details of aeronautical data integrated ground process system’s function were described as follow.
Data download and upload.
In any client terminal, the system could be able to download aeronautical data from airborne record device or mediator record device, as well as wrote data to record device or mediator device, even delete appointed data in record device or mediator device.
Data decode.
For the sake of operation and use of aeronautical data for user, the system need to transfer raw data into value data.
Data preprocess
After downloaded into client terminal and before stored into server, aeronautical data need to be done several preprocess operation by the system, such as abnormal data delete, data value filter, stereotyping, etc.
Data management and transfer
Management to aeronautical data is an important function of aeronautical data integrated ground process system, which includes aeronautical data browse, data index, data searching, data protection. Data transfer is also necessary in the system, which means that transferring the different users’ needed data into right client terminal, and refreshing modified data by users into server.
Data process
Data process in the system includes edit and process of data information, event label, department log, and just data. Process to data also include predigest, compress, and delete.
Data replay
Data application. After the system transfer the selected data by users into the user’s client terminal, aeronautical data’s application would be accomplished in the client terminal. The way of aeronautical data application includes event report forms, failure diagnose and other extended application ways.
System management
For the system operate well, users, devices, pilots, parameters library, data application ways need to be managed by the system.
HARDWARE SYSTEM DESIGN
The Clients/Server(C/S) architecture was selected in the net physical platform, which provided physical foundation for mutual access to data of different units and departments, and its physical architecture described in Fig.1.
Aeronautical data integrated ground process system’s net physical architecture is a hierarchical style, and each air troop’s inner is composed of local area network while C/S way was adopted. Computers of client terminal is ordinary personal computer or notebook PC[3], which were interactive platform between users and the process system and accomplish the work of data download, encode and utilization. Servers could be divided into system servers and data servers. Data servers were arranged in air troop, which were mainly used for aeronautical data and other information’s centralized storage, while system servers were mainly used for users’ permission management and system software management. Data servers could also replace the function of system servers when no system servers in the system. Different department in units of each level were equipped client software which could set the access permission and function permission, and upper level units’ permission contains all the data access permission and function permission of lower level unit. Data severs in tail end air troop only took charge of aeronautical data management and the supply of aeronautical data downloaded and decoded, while system server while system servers took charge of system’s maintain, include users’ management and client terminal software’s refreshment.
Figure 2. System’ Software Module.
The architecture described above had agility in deployment, and backup physical extension. When different unit could not meet the condition of network interlinking, the architecture would be used in a single unit. Once network condition is built up, the architecture could be transplanted whole force net without any modification.
SOFTWARE SYSTEM DESIGN
System Architecture Design
Process system’s client terminal software operate on general OS that version above Windows XP, while server software need to support common database management software such as SQL, Oracle, MYSQL, etc. Ground integrated aeronautical data processing system using three-layer structure of the data layer, business layer, and interface layer, from bottom to top. Data layer was responsible for providing parsed aeronautical data, the business layer accomplished data processing in accordance with the requirements, and interface layer complete the interaction between system and users. Different layers communicated through interface. For example, business layer access parsed data via an data access interface. Interface between layers need to be standardized design.
According to the function, the software system can be divided into eight sections, that is, data download and upload module, data decoder module, data preprocessing module[4], data management and scheduling module, data processing module, data playback module, data application module, the system management module. The relationships between those modules see Fig. 2.
System Expansion Design
I. Data source extensions
format must comply with Decoding data distribution format specification from aeronautical data integrated ground process system’s developers, in order to achieve the use of the decoded data on the client terminal program.
II. Ways to expand data applications
Integrated ground process system’s developers should provide developing norms and notes of data application component on client terminal, including the development of language, physical decoded data format, and provide physical data of parameters and related information to application component in runtime. Data application component’s developing must comply with developing norms and notes provided by process system’s developer. parameters’ physical data format after decoded, or referred as the decoded data format standardization, is the key to secondary data application developing. The format should be provided by integrated ground process system’s developers, and data application component developers use decoded data according to those provided data decode format.
CONCLUSION
With the dramatic increase in aviation record data types, data management and use is a complex, difficult issue. By designing aeronautical data integrated ground process system, and adopting the way of centralized data storage, users using the network data remotely, aeronautical data management and utilization’s efficiency can be improved significantly. Furthermore, by Standard data storage, distribution format, Aeronautical record data type extensions and data application mode expansion can be carried out.
