The Application Software Design Based On The Short-wave Communication Quality Passive Monitoring System

The disastrous space weather could influence seriously on the reliability and safety of the short-wave communication, which will restrict the development of the shortwave communication and cannot meet with increasing requirements(especially in high-speed digital communications). In this thesis, the software is designed, arming at quality evaluation in the nationwide short-wave communication passive monitoring system, by full advantage of the space weather monitoring technology and the short-wave communication quality evaluation method in existence. The software could display 30 sites communication status and the best frequency in real-time, and provide the change trend of best frequency in each link during different periods. This work will lay a foundation on the successful completion of 863 plan <The Monitoring Technology of the Influence of Space Disastrous Weather to the Communication and Electric Power System>. This thesis consists of 3 aspects:(1) The software requirements analyzing. The shortwave communications quality monitoring system has been conducted the thorough research, which includes the short-wave communication quality monitoring equipments, multiple communication equipment networks and complete database data. According to the requirements, the software function modules were refined, the flow diagrams were designed.(2) The software developing. On the basis of fully considering the data interface, speed and stability of data transfer, Qt Creator is chosen as the creating software. The programs were developed in Windows platform by using C/C + + language, which could achieve all the functions such as data reading, data processing, situation displaying.(3) The software testing. According to the prescriptive testing rule, the software passed software testing by the experts from the user. The software system is satisfied with the functional requirement of the user and well stability.
