The Digitized Research Of The Display Units Of A Certain Type Antisubmarine Director

In this article, the modernization amelioration of monitor is reseached in order to settle the ubiquitous problems of naval vessels' display units such as monitor aging, blurry dotting, frequent out of action, spare part stopped production,ect. This program has made modernization amelioration of the old monitors by means of modern electronic technology and computer commanding technology. It principally takes the most popular military reinforced computer's COMPACT PCI technology, picks the Japanese SHARP company's LCD to displace the customary integrative encapsulated CRT display. In view of a special signal transduction interrupter is need to be designed practically and to improve the precision and linearity of dot increasing angle and line increasing angle, the signal transduction interrupter in this research itself has a CPU to faster the A/D transduction and better the tracking precision. It has simplified the power supply by giving up customary CRT high voltage and pulse high voltage. It has introduced all metal hermetical configuration, even the full transparent viewing window has been fixed with appressed metal units by the framework of "conductive glass, EMC electromagnetic defense shim and conductive glue" ,thus can protect the plug-in units inside the case virtually with EMC electromagnetic defense.The main structure of this paper is based on the several major points involved in the the design, highlighting the main contents in the engineering design of the main characteristics and methods. The artical is focused on the technical ways and means to achieve. It consists of three areas. Firstly, it introduces a general design and principles.Secondly, it makes introduction of the hardware, mainly on three boards, that is the isolation signal conversion board, the computer control panel and the power module. As all of the technology of these boards are universal and mature, the introduction of them is on the general is relatively simple and just makes an overview in the article. Thirdly, the introduction of the software design. The main design process is described, as well as some of the specific points on the special.At the same time, focus on the reliability of the design for the display device used in the special environment and introduces the detection test after the transformation of the display device.
