【摘要】：海洋面積在地球表面積中約占據(jù)百分之七十,海洋對全球氣候調(diào)節(jié)有重要作用,海洋風(fēng)場是海洋與大氣相互作用的重要參數(shù),監(jiān)測海洋風(fēng)場對于研究海洋現(xiàn)象、開發(fā)海洋資源、降低海洋水溫氣象預(yù)報的誤差率等方面有重要意義,也符合國家軍事戰(zhàn)略意義。本文研制的全極化微波輻射計定標(biāo)源裝置是空間中心用于海上定標(biāo)場建設(shè),進(jìn)行七個輻射計頻段中的三個全極化頻段定標(biāo),且需要在海洋環(huán)境中連續(xù)無故障工作三年以上,為全極化輻射計提供精確可靠的全極化輻射測量基準(zhǔn)。傳統(tǒng)的兩點定標(biāo)具有較多局限性,而全極化定標(biāo)更加精準(zhǔn),定標(biāo)對象更加多樣化,可以適應(yīng)更多的多樣環(huán)境條件,更加穩(wěn)定和準(zhǔn)確,使用壽命更長。本文針對全極化微波輻射計定標(biāo)源裝置控制部分的運動溫控要求,設(shè)計出一套控制系統(tǒng),以滿足全極化微波輻射計定標(biāo)源裝置的自動運轉(zhuǎn)。論文主要研究內(nèi)容如下:1)在分析全極化微波輻射計定標(biāo)源裝置定標(biāo)過程的基礎(chǔ)上,研究裝置的旋轉(zhuǎn)部分、熱源部分、圓極化反射部分及殼體部分的工作原理,并對其結(jié)構(gòu)和運動的過程進(jìn)行分析。2)根據(jù)全極化微波輻射計定標(biāo)源裝置的運動及溫控要求設(shè)計出一套合理的電控方案;在此基礎(chǔ)上選擇合適的主控單元人機界面及其他元器件,設(shè)計出合理的控制系統(tǒng);并按照要求進(jìn)行電控柜控制面板的設(shè)計,內(nèi)部配電區(qū)、控制區(qū)等區(qū)域劃分及器件的連接和布線,完成裝置控制系統(tǒng)硬件設(shè)計。3)分析全極化微波輻射計定標(biāo)源裝置溫控、旋轉(zhuǎn)及其他部分的控制要求,編寫PLC的內(nèi)部程序及監(jiān)控程序,并完成人機界面的設(shè)計。4)對關(guān)鍵部件進(jìn)行試驗調(diào)試,并在此基礎(chǔ)上進(jìn)行整機運行的試驗分析,以檢測裝置的運行性能。全極化微波輻射計定標(biāo)源裝置試驗結(jié)果表明,滿足裝置樣機研制技術(shù)指標(biāo)要求,裝置的各部分運行符合設(shè)計的要求,運行結(jié)構(gòu)能夠達(dá)到所要求的參數(shù)范圍。
[Abstract]:The ocean area occupies about 70% of the earth's surface area. The ocean plays an important role in the global climate regulation. The ocean wind field is an important parameter for the interaction between the ocean and the atmosphere. Monitoring the ocean wind field is important for the study of ocean phenomena and the development of marine resources. It is important to reduce the error rate of meteorological forecast of ocean water temperature, and it is also in line with the national military strategic significance. The fully polarized microwave radiometer calibration device developed in this paper is the space center used in the construction of the marine calibration field. It is used to calibrate three of the seven radiometers' frequency bands, and needs to work continuously in the marine environment without fault for more than three years. It provides an accurate and reliable reference for the full polarization radiometer. The traditional two-point calibration has many limitations, while the full polarization calibration is more accurate, the calibration object is more diversified, can adapt to more diverse environmental conditions, more stable and accurate, longer service life. In this paper, a set of control system is designed to satisfy the automatic operation of the calibrating device of fully polarized microwave radiometer in accordance with the motion temperature control requirements of the control part of the calibration device of the fully polarized microwave radiometer. The main contents of this paper are as follows: (1) on the basis of analyzing the calibration process of the calibration device of the fully polarized microwave radiometer, the working principles of the rotating part, the heat source part, the circular polarized reflection part and the shell part of the device are studied. The structure and motion process are analyzed. 2) according to the motion and temperature control requirements of the full-polarization microwave radiometer calibration device, a set of reasonable electronic control scheme is designed, and on this basis, the suitable main control unit man-machine interface and other components are selected. The reasonable control system is designed, and the control panel of the electronic control cabinet is designed according to the requirements, the internal distribution area, the control area, and the connection and wiring of the device are divided. Complete the hardware design of the device control system. 3) analyze the temperature control, rotation and other control requirements of the calibration device of the fully polarized microwave radiometer, write the internal program and monitor program of PLC, The design of man-machine interface. 4) the key components are tested and debugged, and based on this, the test analysis of the whole machine operation is carried out in order to test the performance of the device. The experimental results of calibrating device for fully polarized microwave radiometer show that the device can meet the technical requirements of prototype development, the operation of each part of the device conforms to the design requirements, and the operating structure can reach the required range of parameters.
