摘要
实时数据滚动更新在遥测数据监测中占据着重要的地位。但随着遥测数据采集速率的增大,帧间隔越来越小,屏幕刷新引起的闪烁也越来越严重。在此提出通过控件技术实现数据列表滚动功能,并通过内存拷贝,利用双缓存机制,解决数据快速更新引起的闪烁。通过测试证明,该软件运行稳定,操作方便,解决了屏幕闪烁问题,在遥测数据监测中发挥了重要作用。
The real time data updating plays an important role in telemetry data monitoring. But screen flicker caused by refresh becomes more and more serious and the inter-frame space becomes smaller with the telemetry data acquisition rate increasing. A new method of data list scroll is introduced,which is realized with control technology,and through memory copy and double buffer storage mechanism to solve the screen flicker. The practical application shows that the software can work stable and convenient, and has high efficiency in telemetry data monitoring.
