【摘要】：卫星通信是通信行业的一个重要分支,在应急通信方面有着不可替代的优势,特别是当传统的通信设施遭到破坏时,“动中通”卫星通信产品以其通信容量大、机动灵活、快速组网等特点,得到了广泛的应用。本文以车载“动中通”卫星通信地球站的跟踪系统为研究对象。由于载体在行进过程中的运动会使得地球站天线偏离对星姿态,这就需要跟踪系统能够反向补偿载体的运动,通过传感器的测量、主控芯片的计算、控制算法输出电机控制量以及电机的运转使得天线始终保持对准卫星的姿态。在本论文中先简单介绍了“动中通”卫星通信地球站的国内外发展状况和前景、车载“动中通”地球站的基本原理、对星数学基础以及硬件环境,随后阐述了跟踪系统软件的设计,如画框搜索、圆锥跟踪、方位盲扫以及中断处理程序等,紧跟着重点分析了该系统中的关键技术,如串口1通信、丢星重搜索、陀螺仪零点调整原理和模糊PID控制算法,最后给出了该系统在实验室和卫星通信车中的测试结果,并对测试结果进行简要的总结与分析。研究成果经过了多种路况和行车状态的测试,达到了合同规定的指标要求,通过了甲方企业的成果鉴定。
[Abstract]:Satellite communication is an important branch of communication industry, which has irreplaceable advantages in emergency communication. Especially, when the traditional communication facilities are destroyed, the "mobile communication" satellite communication product has a large communication capacity. Flexible, fast networking and other characteristics. It has been widely used. In this paper, we take the tracking system of "moving Zhongtong" satellite communication earth station as the research object. Because of the movement of the carrier in the moving process, the earth station antenna deviates from the attitude toward the star. This requires that the tracking system can reverse compensate the motion of the carrier, through the sensor measurement, the calculation of the main control chip. The control algorithm outputs the motor control quantity and the motor operation makes the antenna always keep the attitude of the satellite. In this paper, the development and prospect of the satellite communication earth station are briefly introduced in this paper. The basic principle of the vehicle "moving through" earth station, the mathematical basis of the star and the hardware environment, then the design of the tracking system software, such as frame search, cone tracking, azimuth blind scanning and interrupt processing program, etc. Then the key technologies of the system, such as serial port 1 communication, satellite loss search, gyroscope 00:00 adjustment principle and fuzzy PID control algorithm, are analyzed. Finally, the test results of the system in the laboratory and satellite communication vehicle are given, and the test results are summarized and analyzed briefly. The research results have been tested by various road conditions and driving conditions. Reached the target requirements stipulated in the contract, and passed the appraisal of the achievements of Party A.
