On basis of the development of modern control technology and apply of the network technology and locale bus - mastering technology ， the paper analyzes the essential element of slab caster system : casting speed ; expatiates in detail on the network structure and communication protocol of ethernet and profibus - dp ; mainly describes the forms of control system configuration ， the function and features of its software and hardware designs ; also, introduces mainly control function of control system, for example ， sequence control, tracking system and operation and monitor function etc. and analyzed and settled the problems of control system in debugging and producing
根據傳統的控制系統存在的一些不完善的問題，基於現代控制技術的發展、網路技術以及現場總線技術的應用，從多方面考慮，決定控制層採用siemens的s7 - 400plc ，現場採用遠程i / o單元，很好的解決了信號量大而又分散的問題。針對生產工藝和機械設備的控制要求，設計了齊全的操作模式和方式，分析了板坯連鑄系統的基本要素：拉矯速度（澆鑄速度） ；根據控制功能的分配及實現，主要說明了plc控制系統的組織結構形式，系統的軟硬體設計的功能和特點。 -
After modification, main technologica and economic indexes have been improved and sequence casting has been realized, finished products of plain carbon and low - alloy grades through secondary annealing eliminated and billet hot delivery and charging primarily realized, which develops the modification of slab ccm at xinyu iron & steel co. ltd
改造后，方坯連鑄機主要技術經濟指標得到了提高，並實現了轉爐鋼全連鑄，消滅了普鋼、低合金鋼二火線材;消滅了二次化鐵;初步實現了方坯熱裝熱送;引發了新鋼公司板坯機改造。 -
This paper is focused on images watermarking algorithms. watermark casting operates in frequency domain, embeds pseudo - random sequence of real number in selected coefficients without image degradation. a blind watermark retrieval technique that can detect the embedded watermark without resorting the original image is proposed, so that the proposed techniques represents a major improvements to those relying on the comparison between the watermarked and original image, which is not practical for a huge image database
本文主要研究針對圖像水印系統的演算法研究，採用偽隨機序列作為水印信號，利用變換域系數作為水印的載體，在不降低圖像質量的前提下達到嵌入水印的目的，在恢復水印的過程中無需原始圖像的參與，相比較那些需要利用原始圖像恢復數據的系統，文中所提出的方案更具有實用性。
