“遥视”作为对无人值守变电站四遥功能必要的补充 ,越来越引起人们的重视。如何高效、及时地传送图像信息是遥视技术的关键所在。介绍了无人值守变电站遥视系统的基本组成原理 ,阐明了压缩传输图像的必要性 ,论述了二维小波变换的原理与Mallat算法 ,在此基础上 ,着重分析了利用二维小波变换压缩传递图像的有效区域并传至调度中心与底图重构出现场实况的方法。仿真结果表明 ,该方法具有使图像失真度小、压缩比大等优点 As a supplement to the four remote functions of unattended substations, Televisions has drawn more and more attention. How to efficiently and timely transfer of image information is the key to remote viewing technology. The basic principle of unmanned substation remote system is introduced. The necessity of compressing the transmitted image is expounded. The principle of two-dimensional wavelet transform and the Mallat algorithm are discussed. Based on the analysis, the application of two-dimensional wavelet transform to compress and transmit The effective area of ​​the image is transmitted to the dispatching center and the bottom map to reconstruct the live scene method. Simulation results show that this method has the advantages of small image distortion, large compression ratio and so on
