【摘要】：天文定位是一門利用天體對(duì)海上船舶進(jìn)行定位的技術(shù)。它定位的設(shè)備簡(jiǎn)單、可靠;觀測(cè)的目標(biāo)是自然天體,因而不受人為控制;定位過(guò)程不會(huì)發(fā)射任何聲、光和電波而具有隱蔽性與抗干擾性,但它受自然條件限制,不能全天候?qū)Ш?定位時(shí)間長(zhǎng),定位過(guò)程復(fù)雜,定位精度低。將單片機(jī)技術(shù)應(yīng)用于天文航海定位,為傳統(tǒng)的天文航海定位的進(jìn)一步發(fā)展與完善,提供了新的思路與理念,而船用天文航海定位計(jì)算器的研制就是其中的一個(gè)重要的研究方向。船用天文定位計(jì)算器不僅解決了船舶定位滯后性的問題,而且縮短了定位時(shí)間,使船舶的定位更加精確,并且操作簡(jiǎn)單、方便攜帶。本設(shè)計(jì)基于STM32單片機(jī)技術(shù),以天文定位原理為理論基礎(chǔ),對(duì)船用天文定位計(jì)算器進(jìn)行設(shè)計(jì)研制。船用天文定位計(jì)算器系統(tǒng)以ARM Cortex-M3微處理器作為控制核心,負(fù)責(zé)數(shù)據(jù)處理、運(yùn)算及計(jì)算器界面實(shí)現(xiàn),以TFT液晶屏為顯示單元,以電阻式觸摸屏為輸入單元。本文依據(jù)天文定位原理,對(duì)單天體定位、雙天體定位、三天體定位構(gòu)造數(shù)學(xué)模型,運(yùn)用相關(guān)計(jì)算公式對(duì)觀測(cè)的天體定位數(shù)據(jù)進(jìn)行數(shù)據(jù)處理并進(jìn)行各天體定位程序的編制。完成了船用計(jì)算器系統(tǒng)各程序模塊的編寫和寫入,如時(shí)鐘模塊及延時(shí)模塊、液晶顯示模塊、串口模塊、觸摸模塊、按鍵模塊、顯示界面模塊,以及對(duì)二元一次超越方程的求解編程和誤差補(bǔ)償編程。航海定位不能完全的依賴衛(wèi)星導(dǎo)航定位系統(tǒng),如GPS系統(tǒng)、伽利略導(dǎo)航系統(tǒng)和北斗導(dǎo)航系統(tǒng)。隨著科學(xué)技術(shù)在天文定位的應(yīng)用和天文定位理論完善發(fā)展,天文定位一定會(huì)成為衛(wèi)星導(dǎo)航定位的有效補(bǔ)充;當(dāng)衛(wèi)星定位出現(xiàn)問題時(shí),船用天文定位計(jì)算器可以有效的保障船舶和人身安全。
[Abstract]:Astronomical positioning is a technology that uses celestial bodies to locate ships at sea. Its equipment is simple and reliable. The object of observation is a natural celestial body and is therefore not under human control; The positioning process does not emit any sound, light and radio waves, but it is hidden and anti-jamming, but it is limited by natural conditions, can not be all-weather navigation, positioning time is long, positioning process is complex. The application of singlechip technology in astronomical navigation provides new ideas and ideas for the further development and improvement of traditional astronomical navigation positioning. The development of marine astronomical navigation positioning calculator is one of the important research directions. The ship astronomical positioning calculator not only solves the problem of ship positioning lag, but also shortens the positioning time. The positioning of the ship is more accurate, easy to operate and easy to carry. This design is based on the STM32 single-chip technology and the astronomical positioning principle as the theoretical basis. The ship astronomical positioning calculator is designed and developed. The marine astronomical positioning calculator system takes ARM Cortex-M3 microprocessor as the control core and is responsible for data processing. The operation and computer interface are realized with TFT LCD screen as display unit and resistive touch screen as input unit. According to the principle of astronomical positioning the single celestial body and double celestial body are located in this paper. A mathematical model for the positioning of three celestial bodies. The data processing of the observed celestial positioning data and the programming of each celestial positioning program are carried out by using the relevant calculation formulas. The program modules of the marine computer system are written and written. Such as clock module and delay module, LCD module, serial module, touch module, key module, display interface module. As well as the binary primary transcendental equation solving programming and error compensation programming. Navigation positioning can not completely rely on satellite navigation and positioning system, such as GPS system. Galileo navigation system and Beidou navigation system. With the application of science and technology in astronomical positioning and the perfect development of astronomical positioning theory, astronomical positioning will be an effective supplement to satellite navigation and positioning. When the satellite positioning problem, the ship astronomical positioning calculator can effectively protect the ship and personal safety.
