Design And Realization Of Weather Facsimile Receiver Web Server Based On DSP

With continuous development of the military and the marine areas, more and more people pay attention to weather information. Weather information is not only used in specialized fields, but also began to be used daily life. Weather fax machine is the main way to get meteorological information, which is very important to the ships in the field of that safety, navigation, sea route choice. At present, facsimile receiver has been widely installed on the large ships weather in our country. on the basis of traditional weather report and concrete experience, It is effective to use weather fax to guarantee the normal navigation of the ship. Current weather fax machines in China, which have specific control methods,are mostly used in the field based on professional design. The weather fax information is shown by the way of printing, and that is not conducive to the image storage and long-term preservation.With DSP technology and network technology, design a versatility, easy to learn the weather fax is possible. Base on the demands for the design of weather facsimile, combine with the fax receiver, this paper designs a fax receiver structure combined with Web Server and fax receiver. And the development of the Web Server Module is discussed in this paper. Web Server module based on the structure of the network server. The module can be connected to the computers. Multi-user can control and watch the fax receiver by the operation of web page browser. Users of different locations can operate the machine through the network. Web page is used as the interface of the system. Users operate the machine with Web browser. The images and the state of receiver information refresh on the Web pates in real time. This kind of fax machine is conducive to long-term preservation of the images by its digitizing the fax image information. It is also convenient to update and install. The system uses DSP as the control unit, and Ethernet controller as the Ethernet controller. the user and the server establish a small local area network through the internet. The user use web page to intercommunicate with the Web Server. Three modes to receive a fax image can be achieved by operating the web page. The pictures that have been received can be browsed in the web page.This paper described the design of the system. The server and network protocol knowledge are described in this paper. Considering the needs and signals of the system, the hardware and software debug results are given. The web page interface, which can certify the function of the system, is described in detail in this paper. The problems of high maintenance costs and lonely user are solved in this paper.
