【摘要】：深海的開發(fā)對我國海洋戰(zhàn)略的實施、海洋經(jīng)濟(jì)的可持續(xù)發(fā)展具有十分重要的意義。海洋環(huán)境復(fù)雜多變,水文監(jiān)測設(shè)備、水下機(jī)器人、無人潛器等都是人類了解海洋的重要工具。這些工具對海洋的深度、溫度、鹽度、流速、地形等參量的測量產(chǎn)生了大量的寶貴數(shù)據(jù),亟需一種可靠的數(shù)據(jù)傳輸系統(tǒng)將其傳至陸地進(jìn)行儲存和分析。基于以上需求,本文設(shè)計了一種深海環(huán)境數(shù)據(jù)轉(zhuǎn)發(fā)系統(tǒng),該系統(tǒng)包括潛標(biāo)和浮標(biāo)兩部分。它的功能是海底的潛標(biāo)將采集和存儲的來自CTD (溫鹽深儀)、ADCP (聲學(xué)多普勒流速剖面儀)等海洋環(huán)境監(jiān)測設(shè)備的數(shù)據(jù),以擴(kuò)頻通信的方式經(jīng)由水聲信道傳至水面浮標(biāo);浮標(biāo)對接收的水聲擴(kuò)頻信號進(jìn)行解調(diào)和解擴(kuò),并通過衛(wèi)星通信方式將解調(diào)后的數(shù)據(jù)發(fā)送至陸地的PC端,最終實現(xiàn)深海環(huán)境監(jiān)測數(shù)據(jù)的遠(yuǎn)程傳輸目的。本系統(tǒng)的運行過程全程自動,無需人工干預(yù),相比傳統(tǒng)的數(shù)據(jù)轉(zhuǎn)發(fā)系統(tǒng)更節(jié)省人力物力,并且具有實時性和便捷性。本文的主要工作有:設(shè)計了系統(tǒng)的整體方案,包括參數(shù)設(shè)計、系統(tǒng)結(jié)構(gòu)方案和硬件方案,對深海耐壓儀器艙進(jìn)行了選型,并在設(shè)計中使用A3LA-RG型銥星衛(wèi)星通信模塊實現(xiàn)衛(wèi)星通信功能。設(shè)計了系統(tǒng)的硬件平臺電路,包括值班板、ARM數(shù)字信號處理板、電源板和底板。設(shè)計了搭載于硬件平臺的MSP430程序,包括MSP430值班程序、串口通信程序及銥星通信程序,基于現(xiàn)有的擴(kuò)頻通信算法動態(tài)鏈接庫設(shè)計了系統(tǒng)的ARM應(yīng)用程序,實現(xiàn)了數(shù)據(jù)的存儲功能、板卡間接口通信功能和銥星控制功能。進(jìn)行了電氣聯(lián)調(diào)、水池試驗和海試。在系統(tǒng)的電氣聯(lián)調(diào)中,對硬件的性能進(jìn)行了充分的測試,對軟件的功能也進(jìn)行了反復(fù)的測試驗證,結(jié)果證明系統(tǒng)可以完成數(shù)據(jù)轉(zhuǎn)發(fā)功能。在實驗室水池條件下進(jìn)行了試驗,對系統(tǒng)的發(fā)射聲源級進(jìn)行了測量,結(jié)果滿足設(shè)計要求;功能驗證試驗驗證了系統(tǒng)可以完成數(shù)據(jù)轉(zhuǎn)發(fā)功能。在外海試驗中,分別進(jìn)行了水平通信試驗、垂直通信試驗和銥星通信功能驗證試驗,水平通信試驗初步驗證了儀器艙的水密性和系統(tǒng)的工作穩(wěn)定性符合設(shè)計要求;垂直通信試驗進(jìn)一步驗證了儀器艙的水密性,在保證通信距離的情況下系統(tǒng)可以準(zhǔn)確無誤的完成數(shù)據(jù)轉(zhuǎn)發(fā);銥星通信功能試驗,準(zhǔn)確無誤的收到了附帶海洋環(huán)境數(shù)據(jù)的郵件,驗證了數(shù)據(jù)轉(zhuǎn)發(fā)鏈路的通暢,系統(tǒng)可以保證數(shù)據(jù)轉(zhuǎn)發(fā)功能的實現(xiàn)。
[Abstract]:The development of deep sea is of great significance to the implementation of ocean strategy and the sustainable development of marine economy. The complex marine environment, hydrological monitoring equipment, underwater vehicles, unmanned submersible vehicles are important tools for human understanding of the ocean. The measurement of ocean depth, temperature, salinity, velocity, topography and other parameters has produced a great deal of valuable data, and a reliable data transmission system is urgently needed to store and analyze it on land. Based on the above requirements, this paper designs a deep-sea environmental data forwarding system, which consists of two parts: submarine and buoy. Its function is that submarine submersible will collect and store data from marine environment monitoring equipment such as CTD (temperature and salt depth instrument), which is transmitted to the water surface buoy by means of spread spectrum communication via underwater acoustic channel. The buoy demodulates and despreads the received underwater acoustic spread spectrum signals, and transmits the demodulated data to the PC terminal of the land by satellite communication, so as to realize the remote transmission of the deep-sea environmental monitoring data. Compared with the traditional data forwarding system, the operation process of the system is automatic and without manual intervention, which saves manpower and material resources, and has real-time and convenience. The main work of this paper is as follows: the whole scheme of the system is designed, including the parameter design, the system structure scheme and the hardware scheme. The A3LA-RG Iridium satellite communication module is used to realize the satellite communication function in the design. The hardware platform circuit of the system is designed, including watch board arm digital signal processing board, power supply board and bottom board. The MSP430 program carried on the hardware platform is designed, including the MSP430 watch program, the serial communication program and the Iridium communication program. Based on the existing spread spectrum communication algorithm dynamic link library, the system ARM application program is designed, and the data storage function is realized. Board card interface communication function and Iridium satellite control function. Electrical adjustment, pool test and sea test were carried out. In the electrical connection of the system, the performance of the hardware is fully tested, and the function of the software is tested repeatedly. The results show that the system can complete the function of data forwarding. The experiment was carried out under the condition of laboratory pool, and the measurement of the transmitting sound source level of the system was carried out, and the results met the design requirements, and the function verification test verified that the system could complete the function of transmitting the data. In the offshore test, horizontal communication test, vertical communication test and Iridium communication function verification test are carried out respectively. The horizontal communication test preliminarily verifies the watertightness of the instrument cabin and the working stability of the system to meet the design requirements. The vertical communication test further verifies the watertightness of the instrument module, and the system can accurately complete the data forwarding under the condition of ensuring the communication distance. The Iridium communication function test has accurately received the mail with marine environment data. The system can guarantee the realization of data forwarding function.
