【摘要】：輪機(jī)模擬器作為航海類院校的重要教學(xué)訓(xùn)練設(shè)備,已經(jīng)在現(xiàn)代輪機(jī)教學(xué)和培訓(xùn)工作中得到廣泛應(yīng)用,并在海運(yùn)人才培養(yǎng)方面發(fā)揮著重要的作用。輪機(jī)模擬器的硬件設(shè)備是操作人員直接接觸的設(shè)備,它可以模擬船舶上的各個真實系統(tǒng),輪機(jī)人員通過按下按鈕,旋轉(zhuǎn)開關(guān),推動手柄等動作與模擬器進(jìn)行交互,而采集這些操作信號的正是一些底層的數(shù)據(jù)采集和數(shù)據(jù)處理板卡,數(shù)據(jù)的實時性和可靠性是保證整個模擬器運(yùn)行良好的重要基礎(chǔ)。所以在整個模擬器形成成品之前,如何能快速、高效、方便的對各種輪機(jī)模擬器硬件板卡進(jìn)行測試,并保證系統(tǒng)的運(yùn)行可靠就變的非常必要。針對以上問題,運(yùn)用嵌入式技術(shù)、網(wǎng)絡(luò)技術(shù)以及無線WiFi通信技術(shù),開發(fā)一套基于WiFi的輪機(jī)模擬器測試系統(tǒng)。該系統(tǒng)以輪機(jī)模擬器的底層分系統(tǒng)硬件設(shè)備板卡作為被控對象,并以常用的輪機(jī)模擬器分油機(jī)硬件板卡為例,設(shè)計帶有無線通信功能的硬件電路。將飛思卡爾生產(chǎn)的FRDM-KL43Z核心控制板與WiFi通信模塊、以太網(wǎng)通信模塊相結(jié)合,作為該測試系統(tǒng)的硬件中央處理平臺。在軟件上以SDK軟件開發(fā)工具包作為微控制器的底層驅(qū)動,為了提高測試系統(tǒng)的可靠性和實時性,向微控制器中移植入μC/OS-Ⅱ嵌入式操作系統(tǒng),同時在上位機(jī)上用配置了JAVA環(huán)境的跨平臺軟件QT開發(fā)專門針對本系統(tǒng)的Andriod手機(jī)APP測試軟件,完成對各個模擬器板卡界面和內(nèi)部邏輯功能的模擬,增加了最終系統(tǒng)測試時的直觀性和方便性。在對該測試系統(tǒng)實際使用時,硬件中央處理平臺相當(dāng)于一個適配層,它包含被測試模擬器底層設(shè)備板卡的各種測試信息,操作人員使用專門設(shè)計的手機(jī)APP通過無線WiFi向其發(fā)出控制指令,經(jīng)其解析后作用到相應(yīng)的被控對象上,從而就可以全面的完成對模擬器底層分系統(tǒng)設(shè)備板卡的測試。通過現(xiàn)場調(diào)試實驗表明,基于WiFi的輪機(jī)模擬器測試系統(tǒng)具有功耗小、使用方便、可靠性高等優(yōu)點(diǎn),在輪機(jī)模擬器所在房間的任何一個位置,可以準(zhǔn)確、高效的完成對整個底層設(shè)備系統(tǒng)的集中測試,并增加了測試時的體驗。本系統(tǒng)對未來輪機(jī)模擬器的通信方式和硬件設(shè)備布局方式亦有一定的參考意義。
[Abstract]:As an important teaching and training equipment in marine colleges, marine simulator has been widely used in modern marine engineering teaching and training, and plays an important role in the training of marine personnel. The hardware equipment of the marine simulator is the equipment that the operator is in direct contact with. It can simulate every real system on board the ship. The engineer can interact with the simulator by pressing the button, rotating the switch, pushing the handle, etc. These operation signals are collected by some underlying data acquisition and data processing boards. The real-time and reliability of the data is the important foundation to ensure the whole simulator to run well. So how to test all kinds of marine simulator hardware card quickly, efficiently and conveniently before the whole simulator is finished, and how to ensure the reliability of the system becomes very necessary. Aiming at the above problems, an engine simulator test system based on WiFi is developed by using embedded technology, network technology and wireless WiFi communication technology. The hardware card of the bottom subsystem of the marine simulator is taken as the controlled object, and the hardware circuit with wireless communication function is designed by taking the commonly used hardware card of the engine simulator as an example. The FRDM-KL43Z core control board produced by Freescale is combined with WiFi communication module and Ethernet communication module as the hardware central processing platform of the test system. In order to improve the reliability and real time of the test system, the embedded operating system 渭 C / OS- 鈪，
