【摘要】：气象仪器显控终端是气象传感器系统研发的重要环节,显控终端作为最重要的人机交互手段,提供使用者对气象仪器的控制手段以及对目标信息的正确反馈。本文开发的显控终端主要实现了对强制通风温度传感器与气象站的状态控制、对实时气象数据的显示、存储和传输工作。主要任务有：一是对气象传感器数据的仪表、实时曲线显示；二是显控终端通信功能的实现,主要包括STM32与显控终端的串口通信以及以太网间服务器与客户端之间的UDP通信；三是实现对气象传感器数据的实时处理、存储和导出工作等。本文涉及强制通风温度传感器与气象站采集系统的几个关键技术的研究,首先对L型导流罩进行优化设计,通过CFD方法对其在不同直径、反射率、太阳辐射强度、气流速度等条件下进行数值计算,采用L-M算法得到辐射误差修正方程进行辐射误差修正,并将强制通风温度传感器与配有传统防辐射罩的温度传感器置于相同环境下进行大气温度观测比对实验。其次,构建与开发一款基于STM32处理器的自动气象站采集系统,该系统主要由温度、湿度、风速风向、辐射、阵列式压力传感器、高精度低噪声测量电路、数据采集系统等部分组成。最后,本文通过强制通风温度传感器与气象站采集系统的总体测试,完成对其实际功能的验证。采用跨平台Qt开发的显控终端具备着“一份源码,多次编译”的优越性,本文在完成基于Cortex-A8处理器的Qt/Embedded显控终端开发后,还将终端成功移植到Windows与Android平台,从而为气象业务人员提供各种工作环境下的作平台。
[Abstract]:The display and control terminal of meteorological instrument is an important link in the research and development of meteorological sensor system. The display and control terminal is the most important means of man-machine interaction. The display and control terminal developed in this paper mainly realizes the state control of forced ventilation temperature sensor and weather station. Display, storage and transmission of real-time meteorological data. The main tasks are: first, the instrument of meteorological sensor data, real-time curve display; The second is the realization of the communication function of the display and control terminal, including the serial communication between STM32 and the display terminal and the UDP communication between the server and the client between Ethernet; The third is to realize the real-time processing, storage and export of meteorological sensor data. This paper deals with the research of several key technologies of forced ventilation temperature sensor and weather station acquisition system. At first, the L-shape diversion cover is optimized and calculated by CFD method under different diameters, reflectivity, solar radiation intensity, airflow velocity and so on. The radiation error correction equation is obtained by L-M algorithm. And the forced ventilation temperature sensor and the temperature sensor with the traditional radiation shield are placed in the same environment to compare the atmospheric temperature observation. Secondly. An automatic weather station acquisition system based on STM32 processor is constructed and developed. The system consists of temperature, humidity, wind speed and direction, radiation, array pressure sensor, high precision and low noise measurement circuit. Data acquisition system and other parts. Finally, this paper through the forced ventilation temperature sensor and weather station acquisition system of the overall test. To complete the verification of its actual functions. Using cross-platform QT development of display and control terminal has the advantages of "one source code, multiple compilation" superiority. After the development of Qt/Embedded display terminal based on Cortex-A8 processor, the terminal is transplanted to Windows and Android platform successfully. In order to provide meteorological personnel with a variety of working environment for the platform.
