【摘要】：海洋面积在地球表面积中约占据百分之七十,海洋对全球气候调节有重要作用,海洋风场是海洋与大气相互作用的重要参数,监测海洋风场对于研究海洋现象、开发海洋资源、降低海洋水温气象预报的误差率等方面有重要意义,也符合国家军事战略意义。本文研制的全极化微波辐射计定标源装置是空间中心用于海上定标场建设,进行七个辐射计频段中的三个全极化频段定标,且需要在海洋环境中连续无故障工作三年以上,为全极化辐射计提供精确可靠的全极化辐射测量基准。传统的两点定标具有较多局限性,而全极化定标更加精准,定标对象更加多样化,可以适应更多的多样环境条件,更加稳定和准确,使用寿命更长。本文针对全极化微波辐射计定标源装置控制部分的运动温控要求,设计出一套控制系统,以满足全极化微波辐射计定标源装置的自动运转。论文主要研究内容如下:1)在分析全极化微波辐射计定标源装置定标过程的基础上,研究装置的旋转部分、热源部分、圆极化反射部分及壳体部分的工作原理,并对其结构和运动的过程进行分析。2)根据全极化微波辐射计定标源装置的运动及温控要求设计出一套合理的电控方案;在此基础上选择合适的主控单元人机界面及其他元器件,设计出合理的控制系统;并按照要求进行电控柜控制面板的设计,内部配电区、控制区等区域划分及器件的连接和布线,完成装置控制系统硬件设计。3)分析全极化微波辐射计定标源装置温控、旋转及其他部分的控制要求,编写PLC的内部程序及监控程序,并完成人机界面的设计。4)对关键部件进行试验调试,并在此基础上进行整机运行的试验分析,以检测装置的运行性能。全极化微波辐射计定标源装置试验结果表明,满足装置样机研制技术指标要求,装置的各部分运行符合设计的要求,运行结构能够达到所要求的参数范围。
[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.
