【摘要】：隨著近幾年海運(yùn)的迅速發(fā)展,由船舶碰撞和極端天氣的影響所造成的落水人員遇險(xiǎn)救助也越來越受到重視,小型化海上個(gè)人應(yīng)急搜救示位標(biāo)即是在這樣的背景下產(chǎn)生的一款落水救生設(shè)備。它能夠迅速的將落水人員的位置信息發(fā)送給周圍救援的船舶和岸基設(shè)備上,從而能夠快速的確定落水者的位置信息達(dá)到快速救助的目的。 本文的設(shè)計(jì)內(nèi)容解決了AIS搜救發(fā)射機(jī)個(gè)人便攜設(shè)備中所必需考慮的兩大問題：小型化和低功耗。小型化利于便攜,低功耗利于長久發(fā)射增加救援時(shí)間。小型化主要通過將電路集成及電路的設(shè)計(jì)和布局優(yōu)化來處理,低功耗則主要通過軟件調(diào)制方式的改進(jìn),匹配電路的優(yōu)化,天線的選取等幾個(gè)方面來改進(jìn),這些工作最終體現(xiàn)在產(chǎn)品上,使得產(chǎn)品的待機(jī)時(shí)間得到顯著的提高,設(shè)備的體積減小一半并且性能也得到了深度的優(yōu)化。 論文的撰寫是從產(chǎn)品的四個(gè)大模塊進(jìn)行描述的,即MCU,鎖相環(huán)(VCO),功率放大器,天線。四個(gè)模塊均依據(jù)小型化和低功耗這兩個(gè)大前提進(jìn)行設(shè)計(jì),鎖相環(huán)頻率的調(diào)試及天線匹配的調(diào)試也是設(shè)計(jì)成功該產(chǎn)品的至關(guān)重要的兩個(gè)部分,最后整機(jī)產(chǎn)品的驗(yàn)證和調(diào)試成功表明了設(shè)計(jì)的可行性并且該產(chǎn)品上市也很受市場的歡迎。
[Abstract]:With the rapid development of maritime transport in recent years, more and more attention has been paid to the rescue of people in distress caused by ship collisions and extreme weather. Miniaturized maritime personal emergency search and rescue marker is a kind of life-saving equipment in water under this background. It can quickly send the location information of the submersible to the surrounding rescue ship and shore-based equipment, so that the location information of the submersible can be quickly determined to achieve the purpose of quick rescue. The design content of this paper solves two problems which must be considered in AIS search and rescue transmitter personal portable device: miniaturization and low power consumption. Miniaturization is good for portable, low power consumption is conducive to long-term launch to increase rescue time. Miniaturization is mainly processed by circuit integration, circuit design and layout optimization, low power consumption mainly through the improvement of software modulation, matching circuit optimization, antenna selection and so on. Finally, the work is reflected in the product, which greatly improves the standby time of the product, reduces the volume of the equipment by half and optimizes the performance of the device in depth. The paper is written from the product of four large modules, namely, MCU, phase-locked loop (VCO), power amplifier, antenna. The four modules are designed according to the two major prerequisites of miniaturization and low power consumption. The debugging of PLL frequency and antenna matching are also the two crucial parts of the successful design of the product. Finally, the successful verification and debugging of the whole product shows the feasibility of the design and the product is very popular in the market.
