分层聚合模型的短波电台显示控制方法

Display Control Method of HF Radio Based on Hierarchical Aggregation Model

短波电台中的串口屏应用于显示项目内容条数多、刷新速率快的场景,常会出现“丢帧”现象,即某些数据内容没有显示出来。针对上述问题,从应用层角度设计一种显示控制方法。首先,在设计规划阶段计算满载核逐条显示当前界面内容所需的命令帧数;当所需命令帧大于额定缓冲帧,依据相邻界面或当前界面显示内容相关性,将离散的界面内容进行分层,分层后对同一个层内数据进行聚合,减少外部控制单元与工业串口屏之间交互命令帧数量。实验表明:较好实现短波电台预期显示效果,在不丢失任何需要显示的内容情况下,降低了短波电台信息显示的短时间内连续处理命令帧数,为预期的功能实现提供保障,提高了开发效率。

The serial screen is used to HF radio display the scene with large number of items and fast refresh rate,and “frame loss” phenomenon often occurs,that is,some data contents are not displayed.Aiming at the above problems,a display control method is designed from the perspective of application layer.Firstly,the command frames required by full-load kernel to display the current interface content bar by bar are calculated in the design planning stage.When the required command frame is larger than the rated buffer frame,the discrete interface contents are stratified according to the correlation between the adjacent interface or the current interface.After stratification,the data within the same layer are aggregated to reduce the number of interactive command frames between the external control unit and the industrial serial port screen.The experiment shows that the expected display effect of serial port screen can be well completed,and the number of command frames can be processed continuously in a short time by industrial serial port screen without losing any content to be displayed,which provides guarantee for the expected function implementation and improves the development efficiency.
