[0030] Embodiment 1

[0031] As Figure 1 shown, in this embodiment, an environment control system based on an unmanned aerial vehicle includes: a light and device controller, a light driver, a lamp assembly, a fan, and a signal input interface. The light and device controller is configured to receive instructions sent by an external system, control the light driver, the lamp assembly, and the fan according to the instructions, and simultaneously obtain the status information of each component within the system through the signal input interface and feedback it to the corresponding external system; the light driver steps up or steps down the power supply provided by the light and device controller, and then drives each lamp assembly with a constant current.

[0032] In this embodiment, by controlling the working mode of the lamp assembly through the light and device controller and collecting the status information of each component under different working modes, the interactivity of the system is improved, the safety of the aircraft during night flight is ensured, and the user experience is enhanced.

[0033] In this embodiment, the external system includes a flight control system, a human-machine interaction system, and an electrical system. Among them, the electrical system is used to provide power for the environment control system; the flight control system and the human-machine interaction system send control instructions to the environment control system and receive the status information fed back by the environment control system. Together with other systems, a complete unmanned aircraft control system is formed to enable the normal operation of the aircraft.

[0034] In this embodiment, the electrical connection diagram inside the environment control system is as Figure 2 shown. The power output of the light and device controller is connected to the light driver, and the light driver is then connected to each lamp assembly. Among them, the start lamp, the take-off lamp, and the fan assembly are directly connected to the power output of the light and device controller.

[0035] As Figure 2 shown, in this embodiment, the lamp assembly includes: navigation lights, anti-collision lights, outline lights, reading lights, atmosphere lights, start lights, take-off lights. Among them, the anti-collision lights include: top anti-collision lights, left rear anti-collision lights, and right rear anti-collision lights; the outline lights include: left outline lights and right outline lights; the navigation lights include: red navigation lights and green navigation lights.

[0036] In this embodiment, the light and device controller of the environment control system is the control core of the entire system, capable of processing instructions from other systems and controlling the lamp assembly according to the instructions, enabling the components to work in the normal open, special stroboscopic, regular stroboscopic, breathing, dimming, and off modes. At the same time, this component can obtain the working status of each lamp assembly and feedback it to other external systems.

[0037] The rated voltage of the lighting and equipment controller component is 24V, which supports a voltage input of +9 to +30V. The maximum working current is 15A, and it can work properly in an environment of -20°C to 60°C. This component has 20 controllable 24V power outputs, and each output has an overcurrent protection function. When the output current exceeds 5A, the output can be disconnected in time. This component has 8 digital signal sampling interfaces and 4 analog signal sampling interfaces, and can sample input signals of 0 to +5V. At the same time, this component also has 2 parallel CAN communication interfaces and can communicate with other systems through CAN.

[0038] In this embodiment, the lighting and equipment controller analyzes the instruction through software and switches the working mode of the lamp component; the working modes of the lamp component include: always on, special stroboscopic, regular stroboscopic, breathing, dimming, and off.

[0039] Table 1 Component Working Mode Correspondence Table

[0040] Normally Open Special Strobe Regular Strobe Breathing Dimming Off Reading Lamp √ √ Ambient Light √ √ Top Anti-Collision Light √ √ Left Rear Anti-Collision Light √ √ Right Rear Anti-Collision Light √ √ Takeoff Light √ √ Startup Light √ √ √ Red Navigation Light 2 √ √ √ Red Navigation Light 3 √ √ √ Red Navigation Light 4 √ √ √ Red Navigation Light 5 √ √ √ Green Navigation Light 1 √ √ √ Green Navigation Light 6 √ √ √ Green Navigation Light 7 √ √ √ Green Navigation Light 8 √ √ √ Left Side Marker Light √ √ √ Right Side Marker Light √ √ √ Fan 1 √ √ Fan 2 √ √

[0041] Among them, the always-on mode means that the component turns on the power supply throughout the process.

[0042] The special stroboscopic mode is unique to the anti-collision lamp and is also called the flash mode. It is manifested as the top anti-collision lamp (also called the upper anti-collision lamp) first lights up and goes out once, and then the left rear anti-collision lamp (also called the left anti-collision lamp) and the right rear anti-collision lamp (also called the right anti-collision lamp) light up and go out simultaneously twice, with a period of 3 seconds. The specific working timing is as Figure 3 shown, where the high level indicates that the power supply of the lamp component is turned on, and the low level indicates that the power supply is turned off. The unit of the horizontal axis is 100ms, and the working cycle is 3000ms.

[0043] The regular stroboscopic mode means that the power supply of the component turns on and off at a set frequency.

[0044] The breathing mode means that the component gradually changes from dark to bright and then from bright to dark at a set frequency, where one bright and one dark is a cycle.

[0045] The dimming mode means that the component is always on at a set brightness.

[0046] The off mode means that the component does not turn on the power supply.

[0047] In this embodiment, different components have different working modes. The corresponding table of the working modes of each component is shown in Table 1 above, where "√" indicates the supported working modes.

[0048] In this embodiment, the working mode of the lamp component corresponds to the navigation state of the aircraft, and the navigation states include: charging state, equipment startup state, power startup state, unlocking state, non-automatic state, and maintenance state.

[0049] In this embodiment, the system represents the navigation state of the aircraft by switching the working modes of each component. The corresponding relationship between the navigation state and the working mode is shown in Table 2.

[0055] When the EH216S is in the device startup state, the start-up lights of the environmental control system switch to the normally open mode, showing a constantly on state, and the other light components switch to the off mode. In this state, the reading lights and the ambient lights can be controlled by the human-machine interaction system to switch to the dimming mode. Its state is as Figure 5 shown.

The red and green lights turn on and off simultaneously for 2 ms; the anti-collision lights switch to the special stroboscopic mode; the outline lights, start lights, and fans switch to the normally open mode, while other lamp components switch to the off mode.

[0059] When EH216S is in the maintenance state, the environmental control system switches to the regular stroboscopic mode with a frequency of 1 Hz, while other lamp components switch to the off mode. In this state, the reading lights and ambient lights can be controlled by the human-machine interaction system to switch to the dimming mode. Its state is as Figure 9 shown.

[0062] In this embodiment, the function of the lamp driver component of the environmental control system is to drive the lamp component. The power supply of the lamp component is provided by the lamp and device controller component, which is a 24V DC power supply and cannot directly drive the lamp component. The lamp driver component can boost or buck the input power supply to make the lamp component work in the optimal voltage or current state. The rated input voltage of the lamp driver component is 24V, supports a voltage input of +21~+30V, and the maximum output power is 15W. It can work normally at -20℃~60℃. The lamp driver includes 9 completely identical driving units, as Figure 11 shown in the internal architecture diagram of the lamp driving unit. The driving unit includes a boost driver and a buck driver.

[0063] In this embodiment, other external systems can control the environmental control system through CAN communication instructions.
