| Embedded multimedia remote monitoring system can reflect the object being monitored vividly and truly in real time state, which make it becomes one of the important means of modernization management, monitoring and control. Comparing with the traditional multimedia monitoring system, embedded remote multimedia system has the characteristics of small volume, high stable image quality, long distance monitor, etc. So it has good applied and developmental outlook.This thesis introduces an embedded multimedia monitoring system composed of two sub-systems, which call embedded terminal sub-system and PC terminal sub-system. Firstly, the system structure design and the definition of functions of sub-system are introduced in the thesis. The communication protocol defined by ourselves is given out too. The design and implementation of PC monitoring terminal software system is the core content of this thesis. The writer designs this software system by module separating software design method. Then sub-modules are designed in detail. The main functions and interface layout are described. ActiveX components and controls design, multicast implement, and database design are detail described too. Then the system test procedure and test result is briefly described. In the end of the thesis, the conclusions on system structure and performance are given out and the development of remote monitoring system in future is also suggested. |
