Embodiment

[0112] This embodiment provides a process-controllable UAV simulation data recording and playback method based on the database, including the following steps:

[0113] Step S1, by creating a MYSQL database, and generating a data table in the data storage module according to the database; the data table is used to store the telemetry data generated by the simulation model module;

[0114] The data table includes UAV simulation data fields, specifically including Id, flight altitude, speed, longitude, latitude, pitch angle, roll angle, and heading angle, and set id as the primary key.

[0115] See attached image 3 , step S1 specifically includes the following steps:

[0116] Step S11, when the UAV simulation system starts to run the task, create a data table structure containing the UAV simulation data field, which is used to store the telemetry data in the current UAV simulation task.

[0117] In this embodiment, the name of the generated data table includes current time inf...

Abstract

The invention discloses a simulation data storage and reading method based on a database, and the method comprises a simulation model module which is used for generating simulation data; the system further comprises a data distribution center, a data storage module and a playback module which are connected in sequence. The data distribution center is further connected with one or more simulation display systems. By arranging the data distribution center, synchronism of the data storage module and the simulation display system in the task playback process of the unmanned aerial vehicle simulation display system is ensured, it is ensured that a single data source drives the whole system, and the technical problem that data reading is asynchronous in the prior art is solved; besides, a data storage module is adopted to control a database to store data, and a data sending service is added, so that the telemetering data is sent to a data distribution center completely according to a format issued by model simulation software when being read, and is issued to the data storage module and a simulation display system through the data distribution center; and driving the unmanned aerial vehicle simulation display system to operate.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle simulation research and relates to data reading, in particular to a method for storing and reading simulation data based on a database. Background technique [0002] UAV simulation software (ground station) is an important guarantee for the safe operation of UAV systems. Its purpose is to visualize the flight data of UAVs. It is of great significance to UAV simulation and has important application value. . In addition to displaying the flight status and instrument information in real time, the UAV ground station also needs a data playback function. The data playback is to reproduce the trajectory of the aircraft mission, flight status and other information, and analyze the flight data of the aircraft through intuitive simulation playback records. [0003] Traditional video playback uses video recording to play back video files to play back the mission process. Since the simulation...
