Based On The Research And Design Of Embedded Digital Voice Teaching System

With the never-ending development and improvment of computer science, networktechnology has already become the mainstream of modern education in the world.Furthermore, the application of the Digital Radio-teaching System has taken fundamentalchanges to the radio-teaching System through its content, means and even the concepts.Meanwhile, the development of network, communication and multimedia technology hasopen up expansive space for the application of Embedded System, which made EmbeddedSystem become another technology focus in the IT industry after PC and internet. In suchpremise, this thesis introduces the research and design of the Digital Audio-teachingSystem based on Embedded System and also makes detailed discussion of theStudent-Machine based on Embedded System.To meet the need of the Digital Radio-teaching System, we construct architecture ofthe system based on the embedded system in this thesis. We choose the Personal Computerfor teachers' terminal and design the embedded system as students' terminal by ourselves.Due to the characteristic of this system, we have the interrelated protocol cut down andscheme out a new one called My Protocol. We accomplish the function of the managementfor teaching-terminal and discuss the students' terminal based on the embedded system indetail. We implement concerned drivers of the students' terminal based on successfullytransplanting theμC/OS-Ⅱto the imbedded system. To support the application of thestudents' terminal we complete the network protocols program. In the end, we provide theresult.
