【摘要】：多接口航向軸角模擬器是使用了數(shù)字式自整角機的嵌入式產(chǎn)品，是船舶操舵陸上仿真系統(tǒng)重要組成之一。在船舶航向過程中，靠羅經(jīng)來測量當(dāng)前航向信息，根據(jù)當(dāng)前航向與目標(biāo)航向作比較，確定打舵角度，進而操控船體航向。在仿真系統(tǒng)中，控制器由控制算法代替，船體由船的數(shù)學(xué)模型代替，而羅經(jīng)的功能由多接口航向軸角模擬器來實現(xiàn)。 軸角模擬器系統(tǒng)能夠在自動、電動工況下按照用戶設(shè)定向外發(fā)送三線形式的自整角機模擬信號和相應(yīng)激磁信號；在聯(lián)調(diào)工況下體現(xiàn)其多接口特性，能夠接收串口、以太網(wǎng)、CAN總線網(wǎng)絡(luò)等多種接口形式的數(shù)字軸角指令信號輸入，接收到的數(shù)字信號經(jīng)過插值、編碼及鎖存后發(fā)送給數(shù)字-軸角信號轉(zhuǎn)換器DSC，由DSC完成最后的自整角機信號變換和輸出任務(wù)。 本文首先介紹了自整角機在嵌入式系統(tǒng)上的應(yīng)用與發(fā)展現(xiàn)況，根據(jù)項目任務(wù)要求進行了多接口航向軸角模擬器的功能需求分析，，根據(jù)功能分析得到的結(jié)論進行了整體系統(tǒng)的邏輯設(shè)計。 硬件部分設(shè)計囊括了電源和散熱模塊、微控制器STM32F103最小系統(tǒng)電路和PC104總線結(jié)構(gòu)、鍵盤和LCD接口電路、輸入接口電路和DSC信號轉(zhuǎn)換電路。根據(jù)實際需要，以I/O端口豐富、支持多種通信接口為依據(jù)選取了STM32F103作為微控制器，以其為核心展開詳細設(shè)計工作。 軟件部分設(shè)計涵蓋了實時嵌入式操作系統(tǒng)μC/OS-Ⅱ的移植、系統(tǒng)任務(wù)分配設(shè)計、系統(tǒng)人機交互GUI界面的設(shè)計，各接口電路硬件的驅(qū)動。在成功將μC/OS-Ⅱ移植到STM32F103上運行后，根據(jù)多航向軸角模擬器功能需求，采用時間輪轉(zhuǎn)法，設(shè)置了不同優(yōu)先級的8個用戶任務(wù)。通過在工程中添加μC/GUI、μIP等軟件包，完成了GUI界面設(shè)計和通信接口數(shù)據(jù)處理等編程工作。 最后借助圖形化編程工具LabVIEW和自整角機-數(shù)字信號轉(zhuǎn)換器SDC完成多航向軸角模擬器的功能測試。測試結(jié)果表明，本文設(shè)計成果能夠完成預(yù)定的多種形式外部接口數(shù)字信號的接收和數(shù)字信號到自整角機信號的轉(zhuǎn)換工作，各項參數(shù)指標(biāo)滿足項目任務(wù)要求，可作為舵機系統(tǒng)仿真實驗工作之用。
