簡介：混凝土攤鋪機是近些年流行的一種路面機械，其調(diào)平裝置在整機性能中占有很重要的地位，是保證路面平整度、提高公路攤鋪質(zhì)量的關(guān)鍵。傳統(tǒng)的調(diào)平裝置采用平衡梁進行測量，利用常規(guī)的控制方式進行控制，取得了較好的控制效果。但為了適應現(xiàn)代高等級公路路面攤鋪的技術(shù)精度的要求，需要不斷的改進其控制系統(tǒng)。本文嘗試使用較先進的傳感器及人工神經(jīng)網(wǎng)絡(luò)控制器來代替?zhèn)鹘y(tǒng)的測量和控制方式，并對其控制效果進行模擬仿真，以期望得到較滿意的控制效果。為了達到這一目標，本文在參考和分析大量現(xiàn)有產(chǎn)品參數(shù)的基礎(chǔ)上進行攤鋪機調(diào)平液壓控制系統(tǒng)的選型設(shè)計。參考現(xiàn)有攤鋪機機型，在選型設(shè)計的基礎(chǔ)上設(shè)計了攤鋪機試驗模型，建立了調(diào)平裝置的近似數(shù)學模型，并對橫縱坡控制系統(tǒng)的穩(wěn)定性和動態(tài)特性進行了分析。依據(jù)其控制模型，文中進行了直接反饋控制、常規(guī)數(shù)字PID控制系統(tǒng)的模擬仿真，確定了常規(guī)控制方式的控制參數(shù)及其控制效果，并在此基礎(chǔ)上采用神經(jīng)網(wǎng)絡(luò)逆控制方法，對調(diào)平系統(tǒng)進行辨識和控制，并對其進行了訓練和計算機仿真。在研究中發(fā)現(xiàn)，傳統(tǒng)的PID控制系統(tǒng)可以取得很好的控制效果，但需經(jīng)過無數(shù)次的試湊，而參數(shù)的調(diào)整必須特別小心，非常敏感，不小心的選取都有可能使控制效果不好，產(chǎn)生振蕩，甚至失穩(wěn)。而利用BP神經(jīng)網(wǎng)絡(luò)的函數(shù)逼近能力，可以在較寬的范圍內(nèi)取得較好的控制效果。在控制的過程中，采用兩個BP網(wǎng)絡(luò)，一個作為神經(jīng)網(wǎng)絡(luò)辨識器NNI進行辨識建模；另一個作為神經(jīng)網(wǎng)絡(luò)控制器NNC。首先將被控對象進行離線辨識，確定NNC的初始權(quán)值再進行神經(jīng)網(wǎng)絡(luò)在線控制，從而能夠進一步提高系統(tǒng)的控制精度。通過對數(shù)字PID和神經(jīng)網(wǎng)絡(luò)兩種控制方式的比較可知，神經(jīng)網(wǎng)絡(luò)控制的跟蹤性能優(yōu)于數(shù)字PID控制。所以為了得到一個快速、準確的自動調(diào)平控制系統(tǒng)本文采用的神經(jīng)網(wǎng)絡(luò)控制器是可行的為進一步對調(diào)平裝置試驗系統(tǒng)進行控制來提高系統(tǒng)的定位精度奠定了基礎(chǔ)。

簡介：隨著鐵路運輸事業(yè)的發(fā)展，全路裝設(shè)有信號連鎖設(shè)備的車站已占現(xiàn)有營業(yè)站的994％，電氣集中車站占連鎖車站的729％，而電氣集中連鎖道岔占連鎖道岔的887％，大型編組站、區(qū)段站幾乎全部實現(xiàn)了電氣集中連鎖。因此，確保鐵路車站信號設(shè)備無故障地良好工作，對鐵路運輸安全具有非常重要的意義。利用新技術(shù)設(shè)備和方法，實現(xiàn)鐵路信號設(shè)備狀態(tài)監(jiān)測和故障診斷，是保障鐵路運輸安全中需亟待研究的重大課題之一。本文正是在傳統(tǒng)的信號分析方法的基礎(chǔ)上，利用現(xiàn)代設(shè)備采集的鐵路信號模擬量與開關(guān)量，將神經(jīng)網(wǎng)絡(luò)和專家系統(tǒng)融入鐵路信號故障診斷之中，形成一個更加完善的趨于智能化的基于神經(jīng)網(wǎng)絡(luò)的鐵路信號故障診斷專家系統(tǒng)。本文分析了鐵路信號典型故障的故障機理，闡述了信號分析與故障診斷的方法，比較了各種方法的特點，針對鐵路信號的典型故障特征，采用BP神經(jīng)網(wǎng)絡(luò)診斷方法，基于WINDOWS平臺，利用面向?qū)ο蟮腣ISUALC，開發(fā)了基于神經(jīng)網(wǎng)絡(luò)的鐵路信號故障診斷專家系統(tǒng)。并且通過采集實際故障信號，對系統(tǒng)所采用的方法進行了功能驗證。實驗結(jié)果表明，通過神經(jīng)網(wǎng)絡(luò)對鐵路信號故障診斷，效果良好；提高了設(shè)備診斷、維修的效率，降低了設(shè)備的維修成本，具有很好的應用前景。

簡介：本文提出了基于現(xiàn)場總線的艦船導航系統(tǒng)網(wǎng)絡(luò)方案。該方案中，綜合導航顯控臺、各導航設(shè)備和各分系統(tǒng)都作為網(wǎng)絡(luò)節(jié)點掛接在CAN總線上，各節(jié)點可以根據(jù)自己的需要從總線上獲取導航信息。這樣設(shè)計提高了整個導航系統(tǒng)的自動化程度及可靠性。該方案還包括兩種異構(gòu)網(wǎng)絡(luò)互連設(shè)備CAN總線RS422轉(zhuǎn)換器和CAN總線ETHER網(wǎng)關(guān)，用于CAN總線、以太網(wǎng)、串行總線之間的網(wǎng)絡(luò)互連和數(shù)據(jù)交換。本文重點介紹了CAN總線ETHER網(wǎng)關(guān)的開發(fā)。網(wǎng)關(guān)以應用廣泛的MCS51單片機為核心，實現(xiàn)了與CAN總線、以太網(wǎng)的通信。本文還對當前的熱點技術(shù)TCPIP協(xié)議作了深入分析，設(shè)計了一個適用于網(wǎng)關(guān)自身系統(tǒng)的輕型協(xié)議棧，使網(wǎng)關(guān)具有了WEB服務器的功能。實驗證明，本方案可以很好的實現(xiàn)多個節(jié)點通信，兩種網(wǎng)絡(luò)互連設(shè)備也可以很好實現(xiàn)異構(gòu)網(wǎng)絡(luò)間的數(shù)據(jù)交換。
