Embodiment 1

Embodiment 1 of the present invention provides an unmanned aerial vehicle system component. FIG. 1 is a structural block diagram of an unmanned aerial vehicle system component according to Embodiment 1 of the present invention. As shown in Figure 1, the UAV system component in this embodiment may include: a remote controller 1 for controlling the drone and glasses 2 for the user to wear;

The remote controller 1 includes a screen 101 that emits polarized light;

The glasses 2 include a polarizing lens whose polarization direction coincides with the polarization direction of the light emitted by the screen 101.

FIG. 2 is a schematic structural diagram of a remote controller 1 in an unmanned aerial vehicle system assembly according to Embodiment 1 of the present invention. As shown in FIG. 2, the remote controller 1 may be provided with a screen 101 for displaying the control state of the drone, and the control state may include, but is not limited to, the position of the drone, the flight speed, the flying height, Flight direction, map around the fuselage, pictures taken by the body, etc.

Correspondingly, the remote controller 1 can also be provided with a button and a joystick for controlling the unmanned person. The machine action, such as controlling the drone to take off, landing, adjusting the flight speed and direction, etc., or the screen 101 can be a touch screen, and the user can control the action of the drone through the touch screen.

The drone can be provided with a propeller and a driving device for driving the propeller to rotate, and the flying function can be realized under the control of the remote controller 1. In addition, the drone can also be provided with a working device such as a camera, a spraying device, etc., and can perform functions such as shooting, farm work, and the like under the control of the remote controller 1.

In order to solve the problem that the user cannot see the screen 101 of the drone and the remote controller 1 under strong light at the same time, in the embodiment, the light emitted by the screen 101 may be polarized light. The screen 101 emits polarized light, which can be achieved by passing the backlight of the screen 101 through a polarizer or the like.

The plane formed by the direction of vibration of the light and the direction in which the light wave travels is called a vibrating surface. The vibrating surface of the light is limited to a certain fixed direction and is called polarized light. The vibrating surface of the light is not limited to a certain fixed direction, that is, along various directions. The intensity of the vibrating light waves is the same, called natural light. For example, sunlight is one of the most common natural light.

The glasses 2 used in conjunction with the remote controller 1 include a polarizing lens, and a polarizing film 201 may be disposed on the polarizing lens. The polarizing film 201 is a film layer that causes natural light to become polarized light, and the polarizing film 201 is used to allow only light of a specific polarization direction to pass through the polarizing lens. In order to realize the function of normally seeing the screen, the polarization direction of the polarizing film 201 of the glasses 2 coincides with the polarization direction of the light emitted from the screen 101 of the remote controller 1. Here, the polarization directions are the same, which means that the polarization directions of the two are the same when the user normally operates the remote controller 1. It should be understood that the polarizing performance of the polarizing lens can be achieved by providing the polarizing film 201, or by modifying the lens material or the like.

FIG. 3 is a schematic diagram of light transmitted through the polarizing film 201 of the screen 101 in the unmanned aerial vehicle system assembly according to the first embodiment of the present invention. As shown in FIG. 3, since the polarization direction of the light emitted by the screen 101 is the same as the polarization direction of the glasses 2, the light of the screen 101 is not weakened when it passes through the glasses 2, and the user can view the light emitted by the screen 101. The screen 101 screen is clearly seen.

4 is a schematic diagram of sunlight passing through a polarizing film 201 in an unmanned aerial vehicle system assembly according to Embodiment 1 of the present invention. As shown in FIG. 4, the sunlight is unpolarized light, and only the light having the same polarization direction as the glasses 2 can pass through the glasses 2, so that the entering of the human eye is greatly weakened. sunlight.

The screen 101 can be a liquid crystal display (LCD) or other display capable of emitting polarized light.

In a practical application, when the user needs to use the drone, the remote controller 1 provided in this embodiment can be used to control the drone, and the glasses 2 matched with the remote controller 1 are worn, and enter the human eye in a strong light environment. The sunlight is effectively weakened, but the light emitted by the remote controller 1 is not weakened, so that the user's line of sight can be well switched between the sky and the remote controller 1 screen 101, and the matte is seen when the drone is viewed, and the screen 101 is viewed. Does not kill the effect, does not hurt the eyes. In the case where the outside light is not very strong, such as cloudy or indoor, the intensity of the screen 101 is not much different from the intensity of the surrounding light, and the remote control 1 can be removed using the glasses 2.

Since the polarization direction of the glasses 2 coincides with the polarization direction of the screen 101, the light emitted by the screen 101 is not weakened by the glasses 2, so the screen 101 does not need to increase the brightness, and the glasses 2 itself does not need to be powered, so no additional power consumption is required. Effectively saves the battery power of the remote controller 1.

The UAV system component provided by the embodiment includes a remote controller 1 for controlling the drone and a glasses 2 for the user to wear, the remote controller 1 including a screen 101 emitting polarized light, the glasses 2 including polarized lenses The polarization direction of the polarized lens is consistent with the polarization direction of the light emitted by the screen, which can effectively solve the problem that the screen 101 of the remote controller 1 cannot be seen under strong light, and can ensure the life time of the remote controller 1 and the unmanned person. The overall performance of the machine system protects the user's eyes from glare.

At the light threshold, the current environment is dark. At this time, the user can be prompted to take off the glasses.

Further, the remote controller may further include an output device such as an indicator light, a buzzer, a vibrator, or the like. The output device can be coupled to a remote control. Correspondingly, the remote controller may issue a prompt to the user in at least one of the following manners when the ambient light intensity is lower than the illumination threshold: the control indicator blinks, the buzzer alarm is controlled, and the vibrator is controlled to vibrate.

For example, the remote controller may include an indicator light and a vibrator, and the indicator light and the vibrator are respectively connected to the control device 4. When the ambient light intensity is lower than the illumination threshold, the control device 4 can control the indicator light to blink while controlling the vibration. The device vibrates and prompts the user.

Alternatively, when the ambient light intensity is lower than the illumination threshold, the control device 4 may also push the prompt information to the user through the screen. For example, the control screen displays “the current environment is dark, please remove the glasses”.

The light threshold can be default. The specific threshold can be determined according to actual needs and the screen parameters of the remote controller. For example, the illumination threshold can be 2000Lx.

Further, the remote controller may further include an input device connected to the control device 4 for the user to input the illumination threshold and send the illumination threshold to the control device 4. The input device may include, but is not limited to, a keyboard, a button, a button, a handle, a dial, and the like.

Alternatively, the screen of the remote controller may be a touch screen, and the user may input information such as an illumination threshold through the touch screen. By setting the illumination threshold independently, the user can meet the individual needs of the user and provide convenience for the user.

Further, the control device 4 may further adjust the brightness of the screen according to the ambient light intensity after acquiring the ambient light intensity. Specifically, the greater the external illumination intensity, the brighter the screen can be adjusted, and the smaller the external illumination intensity, the darker the screen can be adjusted. In some embodiments, the remote control further includes adjustment means for adjusting the brightness of the polarized light emitted by the screen.

Adjusting the brightness of the screen can be achieved by increasing the brightness of the backlight or increasing the aperture ratio of the thin film transistor (TFT). The specific adjustment method belongs to the prior art and will not be described in detail in this embodiment.

By adjusting the brightness of the screen by the ambient light intensity, the screen brightness can be changed to follow the external light intensity, making the screen more suitable for the user to watch.

Further, the remote controller may further include: a timing device. The timing device is configured to prompt the user to take off the glasses after the screen is turned on for a preset time.

The preset time may adopt a default setting, for example, may be one hour. Alternatively, the preset time may be set by a user, and the user may input a preset time through the input device, and the input device sends the preset time input by the user to the timing device. After the screen is turned on, the timing device can start timing, and every other preset time, a prompt is sent to the user to remind the user to take off the glasses to rest.

There are various ways to issue a prompt. For example, you can control the screen to display the reminder message “I have worn glasses for one hour, please take a break”, or the timing device can be connected with an indicator light, a buzzer or a vibrator, etc. The user is prompted to flash the light, control the buzzer alarm, and control the vibration of the vibrator.

By enabling the timing function and prompting the user after a preset time, the user can be reminded to take off the glasses after wearing the glasses for a long time to improve the comfort of the user using the components of the drone system.

The UAV system component provided in this embodiment includes an illumination sensor 3 for detecting external illumination intensity, and a control device 4 connected to the illumination sensor 3 for acquiring the The external light intensity, and when the external light intensity is lower than the illumination threshold, prompts the user to take off the glasses, which can effectively prevent visual fatigue of the user and provide convenience for the user.

For example, determining whether the ambient light intensity is lower than the illumination threshold may be implemented by using a comparator; adjusting the screen according to the ambient light intensity The brightness can be adjusted by adjusting the brightness of the backlight through the amplifier; the preset time can be realized by using the 555 timer.

Further, the remote controller further includes: an attitude sensor and a control device. The control device is connected to the attitude sensor for prompting the user when the attitude sensor detects that the remote controller is in the optimal reading posture; wherein the optimal reading posture is the polarization direction of the light emitted by the remote controller on the screen and the glasses The posture of the polarizing lens when the polarization directions are the same.
