摘要
木材干燥過程由人工控制時(shí)，常常會(huì)因?yàn)榻?jīng)驗(yàn)不足，精神無法長時(shí)間集中而造成不必要的損失。為了解決這一問題決定開發(fā)干燥機(jī)上位機(jī)監(jiān)控系統(tǒng)的軟件。
通過對(duì)木材干燥機(jī)上位機(jī)監(jiān)控系統(tǒng)的需求分析，本設(shè)計(jì)通過Visual Basic的MSComm控件結(jié)合程序代碼的方法實(shí)現(xiàn)上位機(jī)與下位機(jī)的數(shù)據(jù)傳輸。通過將上傳的數(shù)據(jù)存入后臺(tái)的Access數(shù)據(jù)庫實(shí)現(xiàn)數(shù)據(jù)的保存。對(duì)于已經(jīng)保存的數(shù)據(jù)能夠?qū)崿F(xiàn)檢索、查詢功能。并且，可以將雜亂無章的數(shù)據(jù)整理成報(bào)表輸出?；蛘呤且愿庇^的圖例形式顯示出來。在使用圖例顯示的時(shí)候可以選擇觀察的狀態(tài)是實(shí)時(shí)監(jiān)控還是全程顯示兩種方式。本設(shè)計(jì)還可以隨時(shí)查詢下位機(jī)的工作狀態(tài)，查詢下位機(jī)采用的工藝參數(shù)。并將查詢結(jié)果顯示出來。由于，用戶采用的系統(tǒng)可能出現(xiàn)變化，所以本設(shè)計(jì)也具有系統(tǒng)設(shè)定的功能以適應(yīng)用戶的不同需要。
本設(shè)計(jì)基本滿足了監(jiān)控系統(tǒng)的對(duì)上位機(jī)軟件的需要。實(shí)現(xiàn)了數(shù)據(jù)的顯示，數(shù)據(jù)的存儲(chǔ)，數(shù)據(jù)的報(bào)表生成和打印。經(jīng)過測試，系統(tǒng)運(yùn)行穩(wěn)定，能夠滿足工業(yè)需要。

The Software design of monitoring System
Abstract
Timber dry course by artificial when controlling, can because of having inadequate experience often, Spirits is unable to be centralized for a long time and loss caused unnecessary. For solve problem this determine and develop desiccator software of monitoring system, plane of location.
Through demand of monitoring system, plane of location, analyse to timber desiccator, Design and accord with procedure method realize and go to location plane and the next data transmission of machine through Visual MSComm controlling part of Basic originally. Through deposit data that upload in Access data base of backstage supporter realize the save of datum. Can realize and search, inquire about the function as to data that keep already. And, can put the data disorderly and unsystematic in order into a report form to export . Or show in the form of more ocular legend . When use legends to show can choose state that observe to control or show two ways in the whole journey in real time. Design and can also inquire about the next working state of machine at any time originally , inquire about the next craft parameter that plane adopted. And will inquire that the result shows. Because system that user adopt might present and change, design and have function that a system set for by meeting the needs of users' difference too originally.
Design and meet monitoring system to go to need of software, plane of location, basically originally. Having realized the showing of the data, the memory of the data, the report generation and typing of the data. Through test, it is steady for system to run, can meet industry need.
Keywords:Supervise and control the system , VB Telecommunication , the Dta base
