探空气球三维数据采集器的研制

A three-dimensional data acquisition system used in air exploration balloon

主要介绍民航监控系统中的探空气球三维(方位、俯仰、斜距)数据自动采集器的软硬件设计及实现。该采集器的主要功能有:接收探空气球三维编码器数据并处理、换算、显示;接收和显示来自PC机的时间信息;根据PC机不同指令,上传相应时刻的三维数据到计算机。计算机通过MODEM将相应三维数据传到民航空管中心。其中,在显示电路中,提出并使用了一种新的消隐方法,克服了传统静态扫描显示的闪烁现象;在软件上,针对数据的具体特点,提出了化乘除为加减,利用移位、按位补偿处理算法,明显提高效率,保证了信号处理的实时性。

A threedimensional data acquisition system of the air exploration balloon used in the civil aviation is introduced. The main functions of the system are as follows: (1) to process and display the data of the azimuth, elevation and distance of the balloon (2) to receive and display the time information of the PC and (3) to feed back the azimuth, elevation and distance data to the PC. The computer puts the data to the center of the civil aviation air management by Modem. In order to overcome the twinkling of the display a new method of eliminating the trace is used. In according to the data feature a new arithmetic in the software is developed.
