毕业设计论文 基于无线传输的智能双经纬仪小球测风系统 —经纬仪数据收发板设计 摘 要 目前对于局部区域测风经常采用的方法是双经纬仪小球测风。在高空风测量中使用的普通测风经纬仪需手工记录观测数据、手工录入数据计算，同步性和实时性难以保证，会造成较大的误差和人力损耗。 本文提出了一种解决上述问题的方法并设计了一种新的智能化、应用范围广的数字化小球测风系统。在测量过程中只需人工跟踪测风气球，系统能够自动采集测风数据并且自动计算测风结果。整个系统可以由电子测风经纬仪、无线数据收发模块、数据采集板和移动终端设备（笔记本计算机）组成。本文着重研究经纬仪数据收发板的设计，具体分析设计了无线数据收发模块。本文所设计的无线数据收发模块主要由Silabs公司生产的一种微控制器芯片C8051F310和TI公司生产的一种无线芯片CC1020组成。这部分的设计包括：原理图设计，PCB设计和C8051F310的应用程序设计。本文先从整体上介绍了该课题的设计思想和层次结构，然后详细介绍了无线数据收发模块的设计过程，并给出了程序流程图。本设计实现了通过无线数据收发模块把从经纬仪那接收来的数据传送给主机处的数据采集板，并且可以通过主机来控制系统状态的功能。 关键词：C8051F310；CC1020；无线传输；测风系统 The intelligence pilot balloon observation system with dual theodolite based on wireless transmission —theodolite data transceiver board design Abstract At present the common method of anemometry for some areas is the pilot balloon observation with dual theodolite. The common pilot balloon theodolite is used in the observation to record observation data and to calculate input data manually when measure upper level wind. The synchronism and real-time performance can not be achieved and that will cause more mistakes and more manpower wastage. This paper provides a way to solve the problem and designs a new intelligentized and widely applicable digital pilot balloon observation system. In the process of observation the pilot balloon can be man-tracked, and the system is able to record wind data and calculate the result of observation automatically. Whole system comprises electronic pilot balloon theodolite，wireless data transceiver module, data acquisition board and move terminal unit(notebook computer). Important design of this paper is theodolite data transceiver board, and analyses wireless data transceiver module. The wireless data transceiver module comprises the C8051F310, a kind of MCU that is designed by Silabs Inc and the CC1020, a kind of wireless chip that is designed by TI Inc. This part of the design comprises: the schematic diagram design, the PCB design, and the application program design in C8051F31
