Radio Data Acquisition Based On Software Bus In The Radio Monitoring

Radio monitoring need deal with more problems including different devices interactedeach other, heterogeneous module working together, multi-task concurrent and so on. Theseproblems are caused by more and more complex monitoring system structure as the radiomonitoring become grid and intelligent. Based on the field of engineering technology, thispaper proposes one solution of applying the software bus to the radio monitoring. In theprocess of radio monitoring, it is the software bus of radio monitoring that featured as lowcoupling of modules, good scalability and wide universality appear in process customizationand function extension of custom modules. It can be able to make full use of the existingdevices to organize the monitoring network and synchronous sample the different data fromthe multiple heterogeneous devices. It can display the real-time multidimensional data andanalysis different perspectives from different devices when multiple devices complete thesame task to assist each other. It realizes as following:1. To establish the component library of the radio monitoring through extracting thecomponents from the domain analysis.2. Realizing the different kinds of functional models related to component technologyand software reuse structure and the adaptor for the heterogeneous devices, and designing theunified standard protocol to solve the problem of different data formats.3. To design the message mechanism to realize the message passing between the internalparts.4. With designing the different internal storage structure such as task queue to realize thescheduling mechanism, it can be able to get the priority scheduling sequence and complete thenormal switch between the real-time monitoring and offline tasks.It is practice in the national test that shows the software bus ensure the performance ofcomplex monitoring task and the organization monitoring in24hours. The software bus ofradio monitoring system improves the system performance and it has the good applicationvalue.
