The electronic map is used to display the position and flight trajectory of the drone in real time.

Compared with the prior art, the present invention has the following prominent advantages:

(1) Adopting the integrated design concept, the volume and weight of the workstation are greatly reduced, and the portability is good.

(2) Only one operator can operate the entire mobile workstation, which saves human resources and simplifies operations.

(3) The use of solid-state hard drives, waterproof and dustproof keyboards, and touchpads can better meet the needs of field operations.

(4) With the electronic map, not only the position information of the area where the UAV is located can be intuitively obtained, but also the surrounding environmental conditions of the UAV can be obtained, which improves the reliability of UAV flight.

Detailed ways

In order to facilitate those skilled in the art to understand and implement the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, Figure 2 and Figure 3, a portable small UAV ground mobile workstation consists of an upper box 1, a display screen 2, a switch 3, a touch panel 4, a lower box 5, a spring clip 6, and a handle 7. Composed of digital radio station 8, joystick 9, keyboard 10, butterfly hinge 11, power supply module 12 and industrial computer 13; the rear edge of the upper box 1 and the lower box 5 is linked by the butterfly hinge 11, The front edges are connected through the spring clips 6; the handle 7 is fixedly connected to the lower box body 5.

The digital transmission station 8 is a 9XStream (900MHz) digital transmission station of the American XStream Company, and is connected to the industrial computer 13 through an RS232 data line to exchange data.

The joystick 9 is connected to an industrial computer 13 through a USB interface.

The display screen adopts 10.1-inch IPS LCD LG hard screen, and adopts four-screen display: the upper left area is the flight map area of small UAVs; the upper right area is the flight status area of small UAVs; the lower right area is the flight status of small UAVs Control status area; the lower left area is the system setting area.

The flight map area adopts Google Earth electronic map integrating network technology, communication technology and GIS technology, and uses longitude, latitude and altitude information to determine the specific location of small UAVs and display their scheduled flight trajectory and current flight trajectory. By clicking on the flight map, the scheduled flight trajectory can be modified online, and the modified trajectory information is transmitted to the small UAV airborne flight control system through the data communication module.
