The Design And Implementation Of Display&Control Software For The Embedded Radio Tester

Military short-wave and ultrashort-wave radio stations are one of the primarycommunication equipments to transfer information in the army, routine testing the keytechnical indicators of these devices is a proper way to ensure their effectiveness.However, the testing task is generally completed by the traditional manual testingsystem for a long time. This kind of testing system is inconvenient to set up and needs avariety of measuring instruments, it is also low digital and modular. These defects makeit unable to meet the requirements of communication equipment testing.To solve these problems, this paper proposes a radio tester based on embeddedplatform.This radio tester not only integrates a variety of measuring instruments, butalso meet the requirements of device miniaturization and portability. In this case, a fullyfunctional and stable embedded GUI(Graphical User Interface) becomes a necessarypart of this tester, to help users complete the testing task easily.Thus, in this paper, a display&control software for the radio tester is designed andimplemented by the Qt/Embedded tool. As the main control module of the tester, thedisplay&control software could provide the users with some beautiful and easy-to-usegraphical interfaces and rich system management functions.First of all, this thesis proposes the functional and performance requirements for thedisplay&control software in the background of the radio tester’system structure andworkflow. We also build a software operating environment on the basis of embeddedlinux os and Qt/Embedded library.Secondly, we design a layed architecture for the display&control software,it definesdetails of the workflow and interfaces for the functional modules in each layer.The corecontent is to design human-computer interface and control testing task and managesystem resources, we also implements dynamic interfaces to make the software occupyless memory space of RAM(random access memory).Finally, through the test platform, we test the display&control software by the whitebox testing method on host computer to ensure its modules and workflow work well.Futhermore, we port the software on the target machine to verify its function andperformance meet the requirements by the black box testing method.The display&control software runs steadily in the embedded platform, collaboratingwith other hardware and sofeware parts to test the key technical indicators of the radiostation. Meanwhile, this software could be upgraded easily in order to meet the newrequirements. Thus, the display&control software put forward by the thesis has goodengineering value to a certain extent.
