Design And Implementation Of Vedio System Based On Physical Isolation Technology

With the advent of the information age, Internet usage has been an unprecedented development,such as finance, online banking and online shopping profoundly changed people's way of life.However, the network is a double-edged sword, it has also brought about the negative influence, for example, suffered a computer worm invasion of Iran centrifuges, Iran's nuclear program suffered a setback in 2010. Information security is no longer the only thing about personal interests, which already become national security and strengthening information security is imminent. How we can ensure that in the experience of the network to provide all kinds of convenience, it also can avoid its potential threats and the network gap came into being in this demand environment.On the basis of research currently existing netgap on design and implementation of their products has been done. For example, the performance of the equipment cost, system compatibility, scalability, flexibility and friendliness. According to the actual situation,we proposed fault isolation method and repaired the bug. A completion of the existing program code implementation has been finished. We can communicate with each other with UDP protocol. On the basis of analysis of the isolator specific application context that remote video surveillance,We made a discussion on the problems in the program a short board and safety performance deficiencies.The main work of this paper is as follows:1. Design and implementation of the overall architecture of the software. And completed integrated debugging to solve the software logic errors, and improve driver performance.2. By analyzing the system bottlenecks, we proposed solution and provided the provisions of API interface hardware. We achieved the release of the agreement, and designed a proprietary communications protocol, as well as their functions to achieve the operation.3. Learning network programming technology and process thread-locking mechanism, we have done a large number of experiments, completed system connectivity debugging and achieve the basic functions of the system. The whole system can be used to achieve the intended target.
