【正文】 ith practical requirement and internationalstandard. In hardware, the system use singlechip microputer and introduced the choosingcondition of the singleship microputer. The WIM system of the paper described canimplement not only the basic function of gathering data, processing data, display data, andquery data,but preserved the gathering data into the database and print in form. The systemmainly use C language to write in the singlechip microputer, and use Visual C++ towrite in the puter for processing data. The RS232 is used to municate the, the paper use MATLAB R2007 language to model weighing system,simulink and train the weighing datas.Key Words: WeighinMotion System, SingleChip Microputer, System Math Modeling,BP Neural Network目錄第一章 緒論...................................................................1 公路車載動(dòng)態(tài)稱重系統(tǒng)的意義 ............................................1 汽車超限超載的危害...............................................1 公路車載動(dòng)態(tài)稱重課題研究的意義...................................2 公路車載動(dòng)態(tài)稱重系統(tǒng)的國(guó)外研究現(xiàn)狀 ....................................3 公路車載動(dòng)態(tài)稱重系統(tǒng)的國(guó)內(nèi)研究現(xiàn)狀 .....................................4 公路車載動(dòng)態(tài)稱重系統(tǒng)的發(fā)展趨勢(shì) ........................................5 本文研究的主要內(nèi)容及工作簡(jiǎn)述 ..........................................6 本章小結(jié) ..............................................................6第二章 公路車載動(dòng)態(tài)稱重系統(tǒng)整體設(shè)計(jì)思想........................................8 公路車載動(dòng)態(tài)稱重系統(tǒng)硬件系統(tǒng) ..........................................8 稱重板壓力傳感器.................................................8 數(shù)據(jù)采集系統(tǒng)....................................................10 計(jì)算機(jī)系統(tǒng)......................................................10 顯示器系統(tǒng)、打印機(jī)系統(tǒng)..........................................12 動(dòng)態(tài)稱重系統(tǒng)一些輔助硬件設(shè)備....................................13 公路車載動(dòng)態(tài)稱重系統(tǒng)軟件系統(tǒng) .........................................13 數(shù)據(jù)采集軟件程序設(shè)計(jì)............................................14 數(shù)據(jù)預(yù)處理模塊..................................................15 顯示程序設(shè)計(jì)....................................................15 通信程序模塊....................................................15 計(jì)算機(jī)上的軟件設(shè)計(jì)..............................................16 本章小結(jié) .............................................................16第三章 公路車載動(dòng)態(tài)稱重系統(tǒng)數(shù)學(xué)建模...........................................18 公路車載動(dòng)態(tài)稱重系統(tǒng)的傳統(tǒng)建模方法 ....................................18 機(jī)理模型........................................................18 經(jīng)驗(yàn)?zāi)Ｐ?.......................................................19 辨識(shí)模型........................................................20 公路車載動(dòng)態(tài)稱重系統(tǒng)的 BP 神經(jīng)網(wǎng)絡(luò)建模方法 ............................21 BP 神經(jīng)網(wǎng)絡(luò)的結(jié)構(gòu) ...............................................21 輸入層和輸出層節(jié)點(diǎn)數(shù)的確定......................................22 隱含層數(shù)和層內(nèi)節(jié)點(diǎn)數(shù)的確定......................................23 基本 BP 算法原理.................................................24 BP 神經(jīng)網(wǎng)絡(luò)建模方法和傳統(tǒng)建模方法的比較...............................28 傳統(tǒng)建模方法的缺陷..............................................28 BP 改進(jìn)算法的措施和方法 .........................................28 本章小結(jié) .............................................................31第四章 基于 BP 神經(jīng)網(wǎng)絡(luò)的動(dòng)態(tài)稱重系統(tǒng)模型設(shè)計(jì)與實(shí)現(xiàn)............................33 神經(jīng)網(wǎng)絡(luò)控制概述 ..............................
