Simulation scheme of UAV ground station

Simulation scheme of UAV ground station

(Summary description)    Typical UAV systems usually include UAV (also known as autopilot) and its flight control systems, ground control systems, launch and recovery systems, payloads and data links. The ground station is an important part of UAV system, its main function is to monitor and control the UAV’s flight process, flight track, payload, communication link, etc. , and some of the failure to give a timely warning and take the corresponding diagnosis and treatment measures. The ground station is an integrated system, which includes real-time acquisition and analysis of telemetry data, regular transmission of remote control command, and dynamic display of flight status.

Information

1.PROGRAMME OUTLINE:
        Typical UAV systems usually include UAV (also known as autopilot) and its flight control systems, ground control systems, launch and recovery systems, payloads and data links. The ground station is an important part of UAV system, its main function is to monitor and control the UAV’s flight process, flight track, payload, communication link, etc. , and some of the failure to give a timely warning and take the corresponding diagnosis and treatment measures. The ground station is an integrated system, which includes real-time acquisition and analysis of telemetry data, regular transmission of remote control command, and dynamic display of flight status.

 

2.  Introduction of the scheme
     2.1.System composition

 

     2.2.Module introduction
            2.2.1.Simulation link communication module
        Through the simulation of wireless communication equipment, the communication link between Ground Station and UAV is established, the telemetry information of UAV is acquired, and the remote control command of ground station is uploaded. Realize the function of communication parameter selection, open and close serial port. The data transmitted by the UAV is received and placed in the receiving buffer, and then the telemetry packet is parsed, displayed and stored according to the communication protocol format.

            2.2.2.Display and control module of Flight Status Simulation
       After the airborne sensors acquire the Flight Status Information of the UAV, the data are transmitted to the ground station through the communication link in a pre-defined format. According to the displayed data, the ground staff judge the status of the UAV, and transmit the Control Command to the UAV through the data link to control the UAV.

            2.2.3.Simulation data storage and playback module
       The actual flight data is stored, such as airspeed, ground speed, altitude, track, course, roll, pitch, longitude, latitude, etc. . It is also used to store the waypoint information in the planned flight path, through data playback, mainly including data playback and curve analysis, the playback display of stored telemetry data is realized; 2-d relationship curves and 3-d position curves of altitude, velocity and time are drawn when the UAV is in flight or data playback, for Data Analysis. By studying these data, we can find a way to improve the system performance.

            2.2.4.Display and control module of simulation payload data
    The payload is the execution unit of the UAV mission. One of the functions of the ground station is to control the payload by displaying the payload data to ensure the successful completion of the mission. Including electronic maps, virtual aviation instruments and status information display.

Electronic Map

The electronic map display includes three parts: the location marking, the drawing of movement track and the basic operation of the map. The position marking part realizes the marking function of a certain area on the map, which is convenient for the user to observe the situation of a certain position quickly Map basic operations include map zoom in, zoom out, center and roaming functions.

Virtual Instrument
      Virtual Instrument Display (VI) is a combination of virtual aviation instruments and digital display of UAV’s flight parameters, including altitude, speed (airspeed and ground speed) , attitude (Pitch Angle and roll angle) and heading.

Status Information
        Status Information display refers to the use of virtual instruments and graphics to Display Satellite Positioning Quality, UAV power status and data link status.

2.2.5.Introduction to typical interfaces
       The uavs ground workstation interface consists of a mission load control interface and a visual display interface, as shown in the following figure:

Probe load control interface

Visual display interface

1.PROBE LOAD CONTROL INTERFACE:

        The detection load control interface includes UAV mission load sensor parameter control, load detection target information list, two-dimensional situation display chart, current view sensor image information, flight status information display area, load status display and others.

2.Visual display interface:

        The visual display interface is divided into four window views, the upper-left corner is the scene 2D view, the lower-left corner is the 3D view, the upper-right corner is the infrared sensor display window, and the lower-right corner is the optional load display window (infrared, radar, visible light) 

3.Technical Features:
    1.The main flight attitude, flight system status, engine parameters and other flight platform data display and flight process monitoring can be realized, and the flight attitude and engine Manual Operation Control and emergency control can be realized.

    2.To achieve real-time work of the Weapon System Monitoring, control the choice of weapons and launch opportunity.

    3.The assistant decision-making of whether the weapon enters the attack window and the assistant decision-making of manual assistant landing control are realized

    4. Achieve Voice and data communication capabilities with other systems, and data storage and playback and analysis capabilities.

4.APPLICATION SCENARIO:
        The system has wide application in the field of UAV Ground Station System Development, UAV weapon equipment test, command and control system performance verification.
