Design and Realization of Remote Monitoring System Based on Image Block Compression Technology

随着网络技术的不断发展,对计算机信号的远程监控在局域网管理,网络安全,网络教学中有着广泛的应用。在对前辈学者提出的屏幕捕获、图像数据传输及解压缩方法进行研究的基础上,论文提出了一种基于图像分块压缩技术的方法,该方法首先将捕获的屏幕位图进行均匀分块,只传输数据发生变化的图像小块,使得监控画面的实时性得到进一步的增强,并大大降低了网络带宽的占用率。同时为获得良好的用户体验使用无损压缩的霍夫曼编码方法,进一步减少了网络数据量。并且根据用户需求实现了对远程计算机软硬件的控制。

With the continuous development of network technology,the remote monitoring of computer signals has a wide range of applications in the management of LAN,network security,network education.On the basis of the screen capture,image data transmission and compression method proposed by senior scholars,a method is proposed based on image block and compression technology.In this method,the captured screen bitmap uniform block only transport data on the occurrence of changes in the image block,making real-time monitor screen are further enhanced,and greatly reduce the occupancy rate of network bandwidth.At the same time,agood user experience is obtained using the lossless compression of the Hoffman encoding method,to further reduce the amount of network data.And the control of remote computer hardware and software is realized according to the need.
