[0087] In more preferred examples, the mobile phone is connected to the car terminal via WiFi, and the automotive-grade graphics and video processing domain controller of the car terminal is used to control the drone.

[0088] According to a vehicle-mounted drone provided by the present invention, the drone includes a drone projection system and a control system of the drone projection system. The specific implementation methods are as follows:

[0089] The entire system can interact with the drone through a mobile phone or car terminal to control the drone's lighting module and projection module, providing a better experience for drivers and passengers. The system includes a signal input terminal; the drone includes a lighting module, a projection module, and a power supply module.

[0090] The signal input terminal includes a mobile phone terminal and a car terminal.

[0091] The projection module can have a built-in power supply module, or it can be powered by the power supply module carried by the drone. The mobile phone can control the drone through the mobile phone's WiFi, Bluetooth or other connection methods. Similarly, the car terminal can control the drone through the car terminal's WiFi, Bluetooth or other connection methods. The drone controls the lighting module it carries, and the power supply module supplies power to the drone and the lighting module. The projection module carried by the drone can have two control modes, which can be selected according to the specific situation: Control mode one is that the mobile phone or car terminal directly controls the projection module. The projection module can have a built-in power supply module, or it can be powered by the drone's external power supply module; Control mode two is that the mobile phone or car terminal controls the drone, and the drone controls the lighting module, projection module and power supply module.

[0092] by Figure 2 Take the example of the projector module as an example to describe in detail the electronic control logic of the projection module. The mobile phone is connected to the automotive-grade graphics and video processing domain controller through WiFi, Bluetooth or other wireless connection methods. The end customer can also connect to the automotive-grade graphics and video processing domain controller through the high-speed communication interface of the cockpit domain control of the vehicle. The automotive-grade graphics and video processing domain controller can perform tasks such as trapezoidal correction and resolution adjustment. The automotive-grade graphics and video processing domain controller is connected to the high-speed communication module through the high-speed communication interface, and is connected to the dedicated controller for the digital micromirror system control. Thus, the terminal inputs and controls the status of the projection.

[0093] The power supply module carried by the drone provides power for the microcontroller, and it can also be powered by the power supply carried by each module itself. The microcontroller needs to have two power supplies and communications. The first one is the function of the system basic chip, including communication. Its power supply and communication module combined power supply can realize basic tasks such as sleep wake-up, management and power supply. The other power supply and communication module combination unit supplies power to other functional chips in the system. All other chips are powered by the power supply system unit, which contains five or six separate modules to meet the different voltage value requirements of different chips.

[0094] The time-of-flight distance calculation module contains a TOF trapezoidal correction chip and its peripheral circuits. It can perform real-time distance calculation based on the infrared light emitted by itself, and feed the distance information back to the microcontroller based on the real-time distance feedback. The microcontroller makes real-time adjustments to the projection of the digital micromirror system through calculation, such as but not limited to the distortion correction of graphics, etc.

[0095] The microcontroller and the dedicated controller for the digital micromirror system are controlled by a crystal oscillator switch so that the two can work based on the same dynamic standard. Both the microcontroller and the dedicated controller for the digital micromirror system can communicate with the storage unit, and the microcontroller controls the dedicated controller for the digital micromirror system to work.

[0096] The optics of the projection module are implemented as two parts: a light source and a digital micromirror system. The light source emits light and shines it onto the digital micromirror system. The digital micromirror system finally realizes imaging by adjusting the angle of each micromirror and the intensity of the light source. The picture or video animation is finally realized through the control of the circuit.

[0097] The dedicated controller for the digital micromirror system controls the digital micromirror system, i.e., the system that can adjust the angle of the micromirror, through synchronization signals and data. The dedicated controller for the digital micromirror system also controls the digital micromirror power supply module so as to power the circuit of the digital micromirror system. The dedicated controller for the digital micromirror system also controls the temperature control system, which monitors the heat dissipation and light attenuation control of the digital micromirror system. The dedicated controller for the digital micromirror system also controls the light source power supply and control system, which controls the light emitting diode of the light source part, and controls the light color and light brightness.

[0098] by Figure 3 For example, the lighting module system block diagram includes the following functions: the system is powered by the positive electrode KL30 of the car battery. The system includes an anti-reverse protection circuit, and the filter circuit makes the system more stable.

[0099] CAN_FD communicates CAN signals with the system. After the CAN signals are connected to the system, they pass through the power supply and communication module combination unit, which receives the power supply after anti-reverse and filtering, and controls and supplies power to the controller. The boost module has two channels. CHANEL A is the power of KL30 after anti-reverse and filtering, which passes through the boost module; another part of the power source is the power that passes through the power supply and communication module combination unit to the boost module, and the channel output through this part of the power source is CHANEL B. The power of CHANEL A and CHANEL B passes through the buck module together to the battery management module to control the operation of the battery. Such as whether the battery starts to supply power. The buck module reduces the voltage to the voltage required by various actual situations required by the battery management system. The power output by the buck module powers the lighting driver module so that it can control the lighting function.

[0100] The controller interacts with the power supply and communication combination unit, which supplies power to and interacts with the controller. At the same time, the controller interacts with the boost module and the buck module, and controls the motor drive module, thereby controlling the operation of the motor. It also controls the fan drive module, thereby controlling the operation of the fan. It also controls the battery drive module, thereby controlling the operation of the battery. The controller controls the operation of the lighting module by controlling the buck module. The fan is a fan that dissipates heat for the lighting module. The motor is a motor that controls the lighting source to rotate according to the actual mechanical structure. The battery is a module that supplies power to other functional modules of the drone. The battery can be integrated in the lighting module or an external battery assembly. The controller can control the operation of the entire system, and interact and communicate with other submodules below through the UART Can control bus.

[0101] In terms of chip selection, the entire system uses automotive-grade chips and performs various safety-related redundant designs to meet the requirements of functional safety and network security. The present invention can meet the requirements of automotive-grade components for real-time performance and safety. In order to meet the functional safety and network security standards of the software, the software design includes a large number of redundant control design solutions and network information security countermeasures.

[0102] The present invention can interact with the drone through a mobile phone or a car terminal to control the lighting module and projection module of the drone, providing a better experience for the driver and passengers. The control system of the lighting module and projection module carried by the drone includes real-time streaming media transmission link control, data link control mode of real-time feedback of the video or picture taken by the drone to the mobile phone or car machine, and real-time control system of the illumination range and intensity angle of the lighting module or projection module by the mobile phone or car machine, and also includes real-time transparent transmission of video data of the projection system by the mobile phone or car machine and local video or interactive content projection by the projection system itself through its intelligent operating system.
