Problems solved by technology

The shortcomings of this data playback method mainly include: the efficiency of playback processing for large amounts of data is relatively low; only the data is played back at a certain rate, and the data cannot be played back according to the actual recorded time point
Therefore, this method cannot meet the requirements of fast and accurate data playback.

Abstract

The invention provides a measurement and control data playback method of an unmanned aerial vehicle, and belongs to the technical field of computer application. Data playback time is obtained, measurement and control data of the unmanned aerial vehicle is divided into multiple data packets and read in a buffer area gradually, multiple values are set to mark whether a time bar is dragged, whether pause and playback are carried out and whether read-in data is processed, and variables are reassigned according to whether the data is processed. Thus, playback data is positioned accurately. According to the invention, a time code in a data frame is compared with practical playback time so that the data is played back according to the practically recorded time point, the efficiency of playback of a large data bulk is improved, functions including acceleration, deceleration, pause and playback by dragging the time bar are additionally arranged, and thus, requirements for measurement and control data playback of the unmanned aerial vehicle are met.

Description

technical field [0001] The invention belongs to the technical field of computer applications, and in particular relates to a method for playback of unmanned aerial vehicle measurement and control data. Background technique [0002] Data playback technology, as an important part of modern signal detection technology, is the follow-up and derivative of data acquisition technology. Combining it with data acquisition technology and signal processing technology, it has been widely used in many fields such as radar, communication, underwater acoustic telemetry, remote sensing, and seismic survey. With the continuous improvement of people's demand for the performance of signal detection technology, how to quickly and accurately realize the playback of a large amount of historical data and provide effective historical data for signal processing technology has become one of the research focuses of signal detection technology. [0003] UAV is an unmanned aerial vehicle controlled by ...
