Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

As shown in Figure 1, the utility model is a box structure, and the opened box is divided into an upper panel and a lower panel; the upper panel is equipped with a liquid crystal display A; the lower part of the lower panel is equipped with a core computer and a video collector connected to the core computer , data collector, power manager, wireless data transmission equipment, described wireless data transmission equipment and the flight control system communication connection of unmanned helicopter; The lower panel is covered with liquid crystal display B, keyboard, trackball and each communication interface, liquid crystal The left and right ends of the display B are also equipped with liftable remote control rods, which are connected to the core computer through the data collector; the liquid crystal display A, liquid crystal display B, keyboard and trackball are respectively connected to the core computer.

The core computer is connected to two LCD monitors through a Dvi one-to-two conversion cable. One of the LCD monitors is directly connected to the computer with a VGA interface after splitting. The other LCD monitor needs a converter because it lacks an HDMI interface. After the signal is converted from the HDMI signal to the VGA signal, the VGA signal is sent to the LCD display.

The video collector can provide two high-speed video acquisition channels, and this device only uses one of them. The capture jack on the panel is directly connected to the video capture device through a video capture line.

The data collector is an analog to digital signal collector, which can collect 32 input analog signals in a single-ended manner and convert them into 16-bit digital signals for computer recognition. In this device, a total of 14 analog signal acquisition channels are used to identify the current state of the remote control stick.

The two remote control levers on the left and right respectively sense the current positions of the four axes through four sliding resistors, and the two ends of these sliding resistors are respectively connected to the 5V and the ground of the wiring power supply board. The output end in the middle of the remote control lever is integrated into a 37-pin cable port on the wiring power supply board, and connected to the analog signal collector of the computer through the cable. Through this collector, the analog signal output by the joystick is converted into a computer-readable digital signal for processing.

The power manager has another backup battery input in addition to the 220V input. If the 220V power supply suddenly cuts off during use, the power supply can continue to supply the entire system uninterruptedly from the backup battery. The spare battery can be charged through the charging socket on the panel with the special charger for the device. When the charger is inserted into the panel, turn the white power knob to the charging position. When the indicator light on the charger changes to After red, start charging the system. When the battery is fully charged, the indicator turns green.

The human-computer interaction part of the device is composed of a keyboard and a trackball. Both the keyboard and the trackball are USB ports. The operation of this keyboard is no different from that of a normal computer keyboard. The trackball on the panel replaces the function of the computer mouse. Turn the trackball on the panel, and the mouse arrow will move in the corresponding direction immediately.

The UAV control box is pre-installed with UAV ground combat control software, which can control the UAV flight trajectory and various airborne equipment.
