Digital Artillery Rear Sight Set By Technology Research

This article, realizes the artillery firing data numeral to put onmakeup decides as thebackground, systematically studied the C8051F020 monolithic integrated circuit, theHD7279 intelligence control chip,has been absolute and the increase photoelectricityencoder principleand the application, designed has used outside the monolithic integratedcircuit internal fixed time/counter and the piece the logiccounts two methods, realized(bidirectional) dynamic has counted tothe increase encoder with the LED demonstrationas well as with PC at the right moment the correspondence.The paper theoretically analyzed the increase, the absolute these twokinds has beensuitable for the artillery high accuracy firing datasetting photoelectricity encoderprinciple, the structure and theapplication. In view of the use different encoder, proposeddirectlycounts, the logic counts, the decoding counts three system designssolution.Mainly completes the work: Using the HD7279 intelligence chip, hasrealized thekeyboard entry numeral which does not need to sever, andestablished has countedfunction key and so on beginning, safehypothesis, elimination. Has realized four integersand decimaldemonstrations, and the dynamic demonstration encoder counts thevalue;Builds the doubling circuit, through disposes C8051F monolithic integrated circuit PCA,its PWM output took the clock pulse, hasrealized the increase encoder output pulse 4frequencymultiplications; The design phase discriminator and the logic circuit,establishthe encoder revolution axis along, counterclock wise rotationwith the leveltransformation relations, realizes T1, T4 counts with the logic counts two methods tocount; In view of the monolithicintegrated circuit and the PC correspondence in thissystemcharacteristic, arranges draws up the simple correspondence agreement,in thedesign the position machine and the lower position machineprocedure, realizes the datatransmission and the receive. Finally, manufactured has installed the junction panel,connected the encoder 85mm cannons artillery trunnion, carried on the solidartitleryexperiment, has completed on the artillery installing equipmentexperiment.
