Analyses Of Data Transmission And Technology Of Its EMC Based On Image Processing Equipment

The information science is one of the fastest developing knowledge in the word. Theimaging technology and image equipment are a new science and technology whichexpanding human vision function and are a live activity branch. It is necessary to researchthe new theory, the new method, the new arithmetic and the new equipment and applythem to practices. All of them must to study in a whole frame. The frame is known asimage engineering. It applies mathematic, physics, chemistry, photics, electronics,atomic physics, informatics etc. to the image processing. Now the image researching isfocused on the digital image technology. In the general term, it is a whole of the relevanttechnology and is a serial work by using image engineering equipment. Image engineering equipment is called as image equipment, too. It is an electronicdevice which is able to realizing the mapping and the reflection from the physics world tohuman mentality. It concludes two main parts. The first is imaging technology and thesecond is processing technology. And the equipment's task is to having invisible or blurredobject coming into image, and letting human eyes through the image to watch the sceneryof object which cannot be seen in direct. By this way of analyzing and apprehending tothe 2D and 3D image and object, we can get important information to human activities. The equipment is profit from the research results and practice experiences of imageengineering. And it is involved in much technology, such as imaging technology, imagetransmission, processing, analyzing, displaying, auto control, and machine technology,etc... In generally the developing start is its main functions. And firstly sub-modules ofsub-function are partitioned from synthesis to some objects. In the process not only theintegration but also the feasibility of equipment is considered in detail. Some of thesub-modules are software of computer and the others are the electronic circuits or sets. Inorder to synthesizing the hard modules the relationship of them should be well IVunderstudied. It is involved two questions, the one is data transmission, and the other is EMCbetween modules. Generally the electronic parts and modules which developed by our selfare achieved them EMC. But as soon as they are connected each other to form products,the series EMC problems are happing. Because mainly, the reason is the transmission of data, and the electronic connection.So based on the syntheses analysis of the transmission of image engineering equipment, itis significant to research the principle and technology. In the theory, some new methods ofmore kind of transmission data can be found, and compared them to the earlier ones. Inthe technology, the faster speed of the equipments can be gotten, and the area of imageprocessing can be enlarged. The paper, in the first, introduces some of model image equipments. Then, the basicproblems of the paper's topic are discussed in detail. The paper, based on the analyses andresearch of the new transmission technology of image equipments, states the theories andmethods of EMC. The main content is below. From some image processing equipments, the concepts of data stream model in imageequipment are set up. And the last methods of data transmission are specified. From the consideration of hardware, the concepts of the modularized imageengineering equipments come out. Compared with the computer software engineering, theguide principles of partitioning hardware are carried out. Because principles is based onthe EMC. So the entrance of EMC in the image equipments is found. The paper discuses one of the key problem, ——the real time problem of datatransmission, Against the traditional protocol of CSMA of field bus, a new distributingdynamic priority queue(CSMA/DDPQ) is set up for sharing the medium of transmission. For the CSMA/DDPQ, the distributing dynamic priority queue and non...
