摘   要

本設(shè)計主要完成集散管理系統(tǒng)――終端部分的設(shè)計。《集散管理系統(tǒng)》是針對目前東風(fēng)公司各專業(yè)廠的生產(chǎn)車間，生產(chǎn)計劃，調(diào)度指令，零件收發(fā)等一系列的信息溝通與傳遞，完全依賴人工完成。比如車間生產(chǎn)的調(diào)度，每天要根據(jù)產(chǎn)生科下達的生產(chǎn)計劃，制定出車間當(dāng)天的生產(chǎn)計劃，然后分別下達到各個生產(chǎn)班組，甚至下達到設(shè)備操作者手上。然后要經(jīng)常性地了解各種零件的完成情況。這種信息交流模式，在早些年的計劃經(jīng)濟時代，尚能應(yīng)付生產(chǎn)。然而，在如今的市場經(jīng)濟條件下，這種信息交流模式則明顯滯后于市場化的要求。所以，本設(shè)計的目標(biāo)是，終端能夠顯示零件的屬性，如：編號，序號，數(shù)量等，并且上位機PC機能夠控制液晶顯示屏進行顯示，并且每個工位做完相應(yīng)零件的時候，由單片機發(fā)送指令，傳送到上位機之后，任務(wù)下達部門就分配下一個需要完成的數(shù)據(jù)等。

Abstract

This design mainly completes to gather to spread the design of manage the system ―― terminal part.《 Gather to spread to manage the system 》 is aim at each professional factory of the east breeze company currently of the production car, produce the plan, adjust one degree instruction, the spare parts receives and dispatch etc. the information communication of a series with deliver, the complete dependence artificial complete. For example the car produce of adjust the degree, want everyday according to the creation section descend reach of production plan, draw up the production plan of a that very day of a car, then respectively descend attain each produce a set, even descend attain the equipments operation hand up. Then usually want sex ground understands various spare parts to complete the circumstance. This kind of information exchanges mode, early planned economy ages of some years, can cope with the production still. However, under the condition of the market economy of now, after the then obvious slow of this kind of information exchanges mode in the request that market turn. So, the target of this design is, the terminal can show that the spare parts belongs to sex, such as: Serial number, ordinal number, quantity etc., and the place of honor machine PC function controls the LCD manifestation to hold to carry on the manifestation enough, and a time that does to finish to correspond the spare parts, send out the instruction from a machine, after delivering the place of honor machine, mission descend reach the section to assign data etc. that next demand complete.
