【摘要】：船舶作為一個(gè)不可或缺的交通工具,其安全運(yùn)行對(duì)物流運(yùn)輸具有重要影響,船舶的控制管理系統(tǒng)直接決定著船舶的運(yùn)行安全。其中機(jī)艙監(jiān)測(cè)顯示單元是船舶控制管理系統(tǒng)的一個(gè)重要組成部分,是船長與船載設(shè)備重要的信息交換媒介,是船長獲取信息、做出決策并對(duì)相關(guān)系統(tǒng)進(jìn)行控制和監(jiān)督的終端。隨著船舶的快速發(fā)展,傳統(tǒng)的機(jī)艙監(jiān)控顯示單元系統(tǒng)已不能滿足未來航運(yùn)的需求,因此設(shè)計(jì)出一種能實(shí)時(shí)數(shù)據(jù)監(jiān)控并能顯示多種信息且人性化的人機(jī)交互界面,從而為船員提供有效信息、為航運(yùn)過程中的突發(fā)故障提供有效、安全的操作指導(dǎo)。機(jī)艙監(jiān)控顯示單元是一個(gè)典型的嵌入式系統(tǒng),具有嵌入式系統(tǒng)功能強(qiáng)大、軟硬件可裁剪、功耗低等優(yōu)點(diǎn)。本文從硬件平臺(tái)和軟件平臺(tái)兩個(gè)方面對(duì)監(jiān)控顯示單元進(jìn)行設(shè)計(jì)與實(shí)現(xiàn)。硬件方面選用了基于AT91SAM9263設(shè)計(jì)的主控板作為硬件平臺(tái),在此硬件基礎(chǔ)上,裁剪了適合船舶機(jī)艙監(jiān)控顯示單元功能需求的嵌入式Linux操作系統(tǒng)。配置了交叉編譯器、yaffs2根文件系統(tǒng)、bootloader引導(dǎo)程序。利用Qt圖形用戶界面開發(fā)工具完成交互界面GUI的布局設(shè)計(jì),信號(hào)與槽機(jī)制實(shí)現(xiàn)界面復(fù)雜的邏輯關(guān)系。嵌入式數(shù)據(jù)庫SQLite記錄了系統(tǒng)的運(yùn)行故障、設(shè)備數(shù)據(jù)等系統(tǒng)參數(shù)。文中還介紹了Linux系統(tǒng)驅(qū)動(dòng)的開發(fā)流程,對(duì)LCD顯示器、觸摸屏、鍵盤等外圍設(shè)備的工作原理作了闡述。重點(diǎn)介紹了IIC鍵盤、UART串口、LCD幀緩沖以及觸摸屏的驅(qū)動(dòng)設(shè)計(jì)。本設(shè)計(jì)的系統(tǒng)前端數(shù)據(jù)采集單元通過總線方式不斷的收集機(jī)艙設(shè)備參數(shù),經(jīng)過RS-232串口全雙工和顯示單元主控板進(jìn)行通信,交換數(shù)據(jù)。實(shí)現(xiàn)在人機(jī)交互界面上實(shí)時(shí)的顯示機(jī)艙主機(jī)、輔機(jī)和其他相關(guān)設(shè)備的運(yùn)行參數(shù),并對(duì)監(jiān)控?cái)?shù)據(jù)進(jìn)行處理給出相應(yīng)的報(bào)警信息。文章最后對(duì)所設(shè)計(jì)的船舶機(jī)艙監(jiān)控顯示單元系統(tǒng)進(jìn)行了測(cè)試,通過測(cè)試用例的應(yīng)用程序調(diào)用底層驅(qū)動(dòng)來驗(yàn)證設(shè)計(jì)的功能。測(cè)試的結(jié)果用于驗(yàn)證系統(tǒng)設(shè)計(jì)中存在的問題,并對(duì)設(shè)計(jì)中出現(xiàn)的問題提出解決和改進(jìn)的方法。系統(tǒng)在測(cè)試、試運(yùn)行和穩(wěn)定運(yùn)行后,能夠達(dá)到預(yù)期的要求。
[Abstract]:As an indispensable means of transportation, the safe operation of ships has an important impact on logistics transportation. The control and management system of ships directly determines the operation safety of ships. The engine room monitor and display unit is an important part of the ship control management system. It is an important information exchange medium between the captain and the shipboard equipment. It is the terminal for the captain to obtain information, make decisions and control and supervise the related system. With the rapid development of ships, the traditional engine room monitoring and display unit system can not meet the needs of the future shipping. Therefore, a human-computer interface which can monitor real-time data, display multiple information and humanize is designed. It can provide effective information for the crew and provide effective and safe operation guidance for the sudden faults in the shipping process. Engine room monitor and display unit is a typical embedded system, which has the advantages of strong function, software and hardware tailoring, low power consumption and so on. This paper designs and implements the monitor and display unit from two aspects: hardware platform and software platform. On the hardware side, the main control board based on AT91SAM9263 is selected as the hardware platform. On the basis of the hardware, the embedded Linux operating system which is suitable for the function requirement of ship engine room monitor and display unit is cut. Configured the cross-compiler / yaffs 2 root file system bootloader bootloader program. The layout design of the interactive interface GUI is completed by using QT graphical user interface development tool, and the complex logic relationship between the interface and the signal and slot mechanism is realized. The embedded database SQLite records the system parameters, such as system failure, equipment data and so on. The development process of Linux system driver is also introduced, and the working principle of peripheral devices such as LCD display, touch screen, keyboard and so on is described. This paper mainly introduces the IIC keyboard and UART serial port LCD frame buffer and the drive design of touch screen. The system front-end data acquisition unit continuously collects the engine room equipment parameters through the way of bus, and communicates and exchanges data through RS-232 serial port full-duplex and display unit main control board. The operating parameters of engine room mainframe, auxiliary machine and other related equipments can be displayed in real time on the man-machine interface, and the corresponding alarm information is given for the monitoring data processing. At the end of the paper, the system of ship engine room monitor and display unit is tested, and the function of the design is verified by calling the bottom driver by the application program of the test case. The test results are used to verify the problems existing in the design of the system, and the methods to solve and improve the problems in the design are put forward. After testing, trial running and stable running, the system can meet the expected requirements.
