[0032] The aircraft of the embodiment of the present invention is provided with a mechanical interface and an electrical interface for mounting a searchlight, so that the searchlight can be mounted on the aircraft and the light brightness and even the light frequency and other light parameters of the searchlight can be controlled. The searchlight can be mounted on the top, bottom or side of the aircraft to achieve different searchlight functions. The mechanical connection between the searchlight and the aircraft can be a movable connection, so that the searchlight can be installed on the aircraft or removed from the aircraft as needed. In addition, the aircraft can also mount other accessory devices as needed, such as a camera.

[0033] In the embodiment of the present invention, in addition to the searchlight mounted on the aircraft to realize the searchlight function, the corresponding light control logic for the searchlight is also planned in the aspect of automatic control. On the one hand, the searchlight can be controlled to work in a high-brightness working state, and continuously emit light at a high-brightness value higher than the first brightness threshold. For example, the first brightness threshold can be equal to the rated working brightness or a brightness value greater than the rated working brightness, such as a brightness value of 120% of the rated working brightness, to achieve high-intensity light emission to better meet the lighting tasks in certain special circumstances; on the other hand, considering that the searchlight is prone to damage or power consumption when it is in a high-brightness working state for a long time, a high-brightness working protection function is added to the light control logic, that is, when the searchlight is in a high-brightness working state, the first working information of the searchlight will be continuously monitored. If the first working information meets the preset control conditions, the brightness of the searchlight is lowered. In some embodiments, when the first working temperature indicated by the first working information is too high, and / or the working time indicated by the first working information is long, and / or the power indicated by the first working information is low, it is considered that the control conditions are met, and the brightness of the searchlight is lowered to ensure that the searchlight works more safely and stably.

[0034] See also Figure 1 , is a schematic diagram of a working scenario based on an aircraft mounted with a searchlight 101 according to an embodiment of the present invention, in which a user wirelessly controls the aircraft through a remote controller. In one embodiment, the searchlight 101 can be mounted on the top of the aircraft, and can be set on the aircraft body by a rotating connection, so that the light-emitting direction of the searchlight can be adjusted as needed to achieve the searchlighting function. Of course, the searchlight 101 can be mounted on the side or bottom of the aircraft. In one embodiment, the remote controller can be used to control the flight of the aircraft on the one hand, and on the other hand, it can be used to manually control the searchlight 101 as needed. The scene includes a flight system, which includes an aircraft, a searchlight mounted on the aircraft, a control device, and a user terminal; the control device is connected to the searchlight, and the control device can also be connected to the user terminal. The control device is mainly used to perform light-emitting control of the searchlight. In one embodiment, the control device is set on the aircraft, such as Figure 1 As shown, the aircraft includes an aircraft body, specifically including a rotor arm, a propeller, a landing gear, and various electrical devices arranged inside the aircraft body, such as a flight controller, a compass, etc. The aircraft also includes a searchlight and a control device, the searchlight is mounted on the aircraft body, and the control device is connected to the searchlight. In some other embodiments, the control device can also be arranged on the user terminal, that is, the user terminal realizes the function of the control device for executing the light emission control of the searchlight by installing a corresponding application.

[0035] The aircraft can be an automatic flight, and the user can set a cruise route through a remote control or a smart terminal such as a smart phone, a tablet computer, a smart wearable device, etc., and send a control instruction to the aircraft, and the aircraft can execute the cruise route according to the control instruction and fly on the cruise route. At this time, the user can also set the working strategy of the searchlight 101 on the cruise route, and the control device 102 composed of a controller on the aircraft (such as a flight controller or a separately set light controller) or a controller on the searchlight 101 controls the searchlight 101 to work according to the working strategy. In one embodiment, the working strategy may include: working in a high-brightness working state on one or more sections of the cruise route; working in a low-brightness working state (or a normal brightness working state) on the other sections of the cruise route. The brightness value required in the low-brightness working state is lower than the brightness value required in the high-brightness working state. Of course, in other embodiments, more brightness working states can be set, such as a medium-brightness working state in which the brightness value is between the brightness value required for the low-brightness working state and the high-brightness working state, etc.

[0036] The embodiment of the present invention can perform automatic control such as the above on the searchlight 101, or can perform manual control. When needed, the user can increase the brightness of the searchlight 101 by manual adjustment. The control device 102 mentioned above that can control the searchlight 101 can calculate the first maximum working time that the searchlight 101 can work at the brightness value corresponding to the high-brightness working state based on the current first working temperature of the searchlight 101 sensed by the temperature sensor, and / or the remaining battery power for powering the searchlight 101, and remind the user through a prompt message. According to the first maximum working time in the prompt message, the user can choose to turn on the high-brightness mode as needed to put the searchlight 101 in the high-brightness working state. After the searchlight 101 is working in the high-brightness working state, the control device 102 can perform intelligent processing so as to automatically lower the brightness of the searchlight 101 when needed to ensure the safe and stable operation of the searchlight 101.

[0037] See also Figure 2, is a flow chart of a method for controlling the light emission of a searchlight according to an embodiment of the present invention. The method according to an embodiment of the present invention can be applied to a control device. The control device can be, for example, a device arranged on an aircraft, such as a flight controller of the aircraft. The aircraft is controlled by a control terminal of a user, and the control device can be connected to the control terminal of the user in a wireless manner. The control device can also be a device dedicated to controlling a searchlight. In this case, the control device can directly establish a connection with the control terminal of the user in a wireless manner, or one end is connected by wire with a relevant component of the aircraft (such as a communication interface), and a connection is established with the control terminal of the user through the communication interface of the aircraft, and the other end is electrically connected to the searchlight. The control device can also be a control device arranged on a searchlight. In this case, one end of the control device is connected by wire with the flight controller of the aircraft, and a connection is established with the control terminal of the user through the flight controller, and the other end is electrically connected to the searchlight.

[0038] During the flight of the aircraft, the control device can detect the working state of the searchlight set on the aircraft in real time or periodically in S201; in the embodiment of the present invention, based on the luminous brightness of the searchlight, the working state of the searchlight can be divided into a high-brightness working state and a low-brightness working state, and being in the high-brightness working state means that the luminous brightness of the searchlight is higher than the preset first brightness threshold, and if the luminous brightness of the searchlight is lower than the preset first brightness threshold or the luminous brightness of the searchlight is lower than the preset second brightness threshold, it can be considered that the searchlight is in the low-brightness working state, wherein the second brightness threshold is lower than the first brightness threshold. In addition, the first brightness threshold is set according to the rated working brightness of the searchlight, for example, the first high brightness threshold can be set to the rated working brightness or 120% of the rated working brightness, or even greater. During the flight of the aircraft, the control device can detect whether a high-brightness control instruction is received, and if a high-brightness control instruction is received, the searchlight is triggered to enter the high-brightness working state, so as to meet the user's high-brightness lighting needs. The high brightness control instruction may be a brightness control instruction issued by a user terminal, or may be a brightness control instruction automatically generated according to a working strategy during the automatic flight according to the cruise route mentioned above.

[0039] In addition, in one embodiment, before detecting the working state of the searchlight set on the aircraft, the current flight state of the aircraft can also be obtained. If it is in the first flight state, the searchlight is controlled to work in a low-brightness working state, and working in the low-brightness working state means that the luminous brightness of the searchlight is lower than the preset second brightness threshold; if it is in the second flight state, the searchlight is controlled to work in a normal-brightness working state, and working in the normal-brightness working state means that the luminous brightness of the searchlight is the rated working brightness. When the aircraft is in the first flight state, the detection of the working state of the searchlight on the aircraft will not be triggered, because at this time, in order to avoid irritating the eyes of the control user when the aircraft has just taken off, the searchlight will be set to work in a low-brightness working state in the embodiment of the present invention, because high brightness may cause temporary blindness of the user and damage the eyes. Therefore, in the embodiment of the present invention, if the aircraft is in the first flight state, the searchlight is controlled to work in a low-brightness working state. In one embodiment, the second brightness threshold is less than or equal to the rated working brightness, and the rated working brightness is less than or equal to the first brightness threshold mentioned above.

[0040] The aircraft being in the first flight state may mean that: the flight altitude included in the flight parameters is lower than the preset flight altitude threshold, and / or the distance between the aircraft and the control terminal included in the flight parameters is less than the preset distance threshold. The aircraft being in the second flight state means that: the flight altitude included in the flight parameters is higher than or equal to the preset flight altitude threshold, and / or the distance between the aircraft and the control terminal included in the flight parameters is greater than or equal to the preset distance threshold. The control terminal may refer to a control terminal related to the aircraft, such as a control terminal for controlling the flight of the aircraft, etc. For example, if the flight altitude represented by the flight parameters of the aircraft is less than 10m (10m is an empirical value, which can be adjusted), and / or the flight distance represented by the flight parameters is less than 10m (10m is an empirical value, which can be adjusted), the searchlight is automatically controlled to emit light at a second brightness threshold (such as 30% of the normal working brightness value) and below. In this way, a prompt that the searchlight can be used normally can be made, and damage to the user's eyes can be avoided.

[0041] Furthermore, in one embodiment, if the aircraft is in the second flight state, the searchlight can be controlled to operate in a normal brightness operating state, and operating in a normal brightness operating state means that the luminous brightness of the searchlight is the rated operating brightness. Generally, a rated operating brightness can be set for a lamp, and in the second flight state, the brightness of the searchlight may not have an adverse effect on the user's eyes. For example, if the flight altitude indicated by the flight parameters of the aircraft is greater than 10m (10m is an empirical value, which can be adjusted), and / or the flight distance indicated by the flight parameters is greater than 10m (10m is an empirical value, which can be adjusted), the searchlight is automatically controlled to emit light at the rated working brightness.

[0042] After determining the working state of the searchlight, the control device acquires the first working information of the searchlight in S202 when the working state of the searchlight is a high-brightness working state. During the flight of the aircraft, as described above, the searchlight may work at a brightness higher than the first brightness threshold based on a pre-set working strategy of the searchlight or manually adjusted by the user. At this time, the searchlight is in a high-brightness working state, and it is necessary to acquire the first working information of the searchlight in real time or periodically in a shorter period. In an embodiment of the present invention, the first working information includes any one or more of the working time, the first working temperature, and the battery power. Among them, the battery power refers to the power of the battery that powers the searchlight, and the battery that powers the searchlight can be the battery of the aircraft or a separate power supply battery. In one embodiment, the working state of the searchlight can be judged according to the control operation of the searchlight, for example, when receiving a user operation of adjusting the searchlight to a high-brightness working state on the control interface, or for example, detecting a user operation of adjusting the brightness of the searchlight to the maximum value through a physical button such as a knob. The working state of the searchlight can also be determined based on the current brightness. For example, if the brightness of the searchlight is determined to be higher than the rated brightness threshold (or the first brightness threshold) within a certain time range, the searchlight is considered to be working in a high-brightness working state. If the brightness of the searchlight is determined to be equal to the rated brightness threshold within a certain time range, the searchlight is considered to be working in a normal working state. If the brightness of the searchlight is determined to be lower than the rated brightness threshold (or the second brightness threshold) within a certain time range, the searchlight is considered to be working in a low-brightness working state.

[0043] After acquiring the first working information of the searchlight, the control device judges the first working information. In S203, if the first working information satisfies the preset control condition, the control device adjusts the current working luminance of the searchlight according to the preset brightness value; the preset brightness value is lower than the first brightness threshold, the preset brightness value can be the rated working brightness or a brightness value lower than the rated working brightness, and the first brightness threshold can be the rated working brightness or a brightness value greater than the rated working brightness. The control condition is set to enable the searchlight to work safely and stably. If the control condition is met, the working state of the searchlight needs to be controlled to avoid safety accidents.

[0044] In one embodiment, the obtaining of the first working information of the searchlight may include: obtaining the working time of the searchlight in the high-brightness working state, the control condition indicates a first time threshold, and the first working information satisfies the preset control condition including: the working time is greater than or equal to the first time threshold. The first time threshold indicated by the control condition may be an empirical value, and the first time threshold may be determined by recording multiple measured time of the searchlight during actual flight and use of the searchlight, and the multiple measured time refers to the time when the searchlight works in the high-brightness working state under different ambient temperatures and / or working temperatures and the working temperature just reaches a certain warning temperature threshold. The warning temperature threshold is mainly determined based on the safety lighting factor of the searchlight. A searchlight with an operating temperature of the warning temperature threshold may be damaged or even explode due to excessive temperature. Therefore, it is necessary to set a warning temperature threshold to ensure the safe operation of the searchlight.

[0045] In one embodiment, the first duration threshold value can also be determined based on the first maximum working duration of the searchlight. The first maximum working duration of the searchlight in the high-brightness working state can be estimated; the first duration threshold value is set based on the first maximum working duration, for example, the first maximum working duration is set as the first duration threshold value, or a duration less than the first maximum working duration is set as the first duration threshold value. The first maximum working duration can be calculated at the time of just taking off, or at any time before the searchlight is controlled to enter the high-brightness working state. The first maximum working duration is estimated based on the working temperature of the searchlight in the high-brightness working state or the working temperature when entering the high-brightness working state. In some embodiments, the working temperature in the high-brightness working state based on which the first maximum working duration is estimated is also a reference value, not the actual measured value in the high-brightness working state of this operation. Based on the reference value, an approximate first maximum working duration is estimated, and the first duration threshold value in the control condition is set based on the maximum working duration. In some embodiments, the first maximum working duration can also be a preset constant value.

[0046] In one embodiment, the obtaining of the first working information of the searchlight may also include: obtaining the first working temperature of the searchlight in the high-brightness working state; the control condition indicates a first temperature threshold, and the first working information satisfies the preset control condition including: the first working temperature is greater than or equal to the first temperature threshold. The first temperature threshold may be related to the warning temperature threshold mentioned above. In one embodiment, the first temperature threshold may be the warning temperature threshold, or the absolute value of the difference between the first temperature threshold and the warning temperature threshold is less than a preset value. The first temperature threshold or the warning temperature threshold is determined according to the rated working temperature of the searchlight. The temperature of the searchlight in the high-brightness working state may be collected by setting a temperature sensor at the lamp holder of the searchlight.

[0047] If it is detected that the first working temperature of the searchlight is greater than the preset warning temperature threshold, a high temperature warning prompt is issued. Once the warning temperature threshold is reached, a prompt message needs to be issued to the user. In one embodiment, the reminder can be given by controlling other lights on the aircraft to flash. In one embodiment, the user can also be notified on the control terminal by sending a notification message on the communication link. The role of setting the warning temperature threshold is that: in the case where the first working information is the working time, when the working time is less than the first time threshold indicated by the control condition, if the first working temperature exceeds the warning temperature threshold, a warning will also be issued. In this way, when the working time does not meet the control condition, the user can be reminded that the temperature is too high, so that the user can perform corresponding safety control, such as lowering the brightness or even turning off the searchlight. The role of setting the warning temperature threshold is also that even if the searchlight does not enter the high-brightness working state, if the working temperature is detected to be higher than the warning temperature threshold, the user can also be reminded that the working temperature is too high, so that the user can perform corresponding safety control, such as lowering the brightness or even turning off the searchlight.

[0048] In one embodiment, please refer to Figure 3 , is a schematic diagram of a method for issuing a brightness adjustment indication after adjusting the current luminous brightness of the searchlight according to a preset brightness value, that is, lowering the luminous brightness of the searchlight in an embodiment of the present invention. In an embodiment of the present invention, the control device obtains the second working information of the searchlight after the luminous brightness is adjusted in S301, and if the second working information meets the high-brightness working condition in S302, a brightness adjustment indication is issued.

[0049] In one embodiment, S301 may include obtaining the second operating temperature of the searchlight after adjusting the luminous brightness; the current second operating temperature of the searchlight may also be obtained by a temperature sensor disposed at the searchlight holder. Generally, after lowering the brightness, the operating temperature of the searchlight will decrease. The control device may estimate the second maximum operating time of the searchlight at the second operating temperature and in the high-brightness operating state; the second maximum operating time may be calculated and output based on a pre-set estimation model and the second operating temperature as input. The control device issues a brightness adjustment instruction when the second maximum operating time is greater than a preset second time threshold. In other words, if the estimated second maximum operating time is greater than a preset second time threshold, such as a second time threshold of 2 minutes, 5 minutes, etc., the user is notified that the searchlight can be put into a high-brightness operating state again. The preset second time threshold is mainly set by the user in advance according to the searchlight task to be performed. For example, when a mine user needs to observe a certain device, the duration of controlling the aircraft to fly around the device and observe the device is 2 minutes, then the second time threshold is set to two minutes. At any time, as long as it is estimated that the searchlight can work in a high-brightness working state for two minutes, a brightness adjustment instruction can be issued.

[0050] In other embodiments, whether to issue a brightness adjustment instruction may also be determined based on temperature and operating time, respectively. The second operating temperature of the searchlight after the luminous brightness is adjusted may be obtained, and the high-brightness operating condition indicates a second temperature threshold, and the second operating information satisfies the high-brightness operating condition and includes: the second operating temperature is less than or equal to the second temperature threshold. Alternatively, the second maximum operating time that the searchlight can operate in a high-brightness operating state after the luminous brightness is adjusted may also be estimated, and the second time information satisfies the high-brightness operating condition and includes: the second maximum operating time is greater than or equal to the second time threshold.

[0051] In an embodiment of the present invention, the brightness adjustment indication is used to indicate to the user that a prompt message is sent to indicate that the searchlight can work in a high-brightness working state; and / or, the brightness adjustment indication is used to control the searchlight to enter a high-brightness working state. That is to say, the brightness adjustment indication may be just a prompt message, which sends a prompt to the user terminal through a communication link that the searchlight can work in a high-brightness working state. The brightness adjustment indication may also be used as a control instruction to directly control the searchlight to work in a high-brightness working state. Or the effect of the brightness adjustment indication is: after sending the prompt message, if no instruction from the user to stop working in high brightness is received, the searchlight is directly controlled to work in a high-brightness working state.

[0052] In addition to being provided with a searchlight, the aircraft may also be provided with other functional accessories. In one embodiment, the aircraft is also provided with a night navigation light. In the embodiment of the present invention, the function of the night navigation light is mainly used to locate and prompt the position of the aircraft in the air at night or in a relatively dim light environment (the light intensity sensed by the light sensor is lower than a preset threshold). In some emergency situations, such as the searchlight cannot emit light (for example, the searchlight fails), etc., it can effectively prompt the user of the position of the aircraft in the air. In one embodiment, the purpose of controlling the light emission of the night navigation light is mainly to satisfy the requirement of being able to prompt the controlling user or other aircraft or other related users of the position of the aircraft in the air at a distance of 3 miles / 5 kilometers or even farther.

[0053] The lighting control of the night navigation light mainly includes: if it is detected that the flight parameters of the aircraft meet the night navigation light control conditions, then according to the first night navigation light prompt rule, the night navigation light is controlled to work at a low brightness level; or, if it is detected that the flight parameters of the aircraft do not meet the night navigation light control conditions, then according to the second night navigation light prompt rule, the night navigation light is controlled to work at a high brightness level. The flight parameters include the flight altitude of the aircraft and / or the flight distance of the aircraft from the control terminal of the ground user during the flight mission. Detecting whether the flight parameters of the aircraft meet the night navigation light control conditions includes: detecting whether the flight altitude of the aircraft is less than the first altitude threshold and / or detecting whether the flight distance of the aircraft is less than the preset first distance threshold. If the judgment result is yes, it is considered that the flight parameters of the aircraft meet the night navigation light control conditions. If the judgment result is that the flight altitude of the aircraft is greater than the first altitude threshold and / or the flight distance of the aircraft is greater than the preset first distance threshold, it is considered that the flight parameters of the aircraft do not meet the night navigation light control conditions. The first height threshold may be, for example, an empirical value such as 4.5 m, and the first distance threshold may also be, for example, an empirical value such as 4.5 m.

[0054] The second brightness threshold indicated by the low brightness level is less than the first brightness threshold indicated by the high brightness level. The second brightness threshold can be, for example, an empirical value such as 30% of the brightness of the night navigation light, and the high brightness level can be, for example, a preset value of 100% of the brightness of the night navigation light. The purpose of setting the first height threshold and / or the first distance threshold, and setting the first brightness threshold and the second brightness threshold as the basis for controlling the light emission of the night navigation light is: on the one hand, in the case of low altitude or close to the user, it will not cause stimulation or interference to the user's eyes, will not affect the user's vision, and can ensure that the user can control the aircraft safely. On the other hand, after the aircraft flies far away, it can also achieve the function of prompting the position of the aircraft in the night flight mode, for example, when the aircraft is flying in the air, at a distance of 3 miles / 5 kilometers or even farther, the controlling user or other aircraft or other related users can also discover the existence of the aircraft.

[0055] The following is an example to illustrate the embodiment of the present invention.

[0056] When the drone takes off at night, the user can choose to turn on the night flight light on the APP. After turning it on, the searchlight is controlled to emit light at a lower brightness (within 30%, adjustable by the user) (the searchlight working state at this time can be regarded as a low brightness working state). When the distance from the user is more than 8m (adjustable by the user), the searchlight is controlled to emit light at 100% brightness, and 100% brightness is the rated working brightness of the searchlight (the searchlight working state at this time can be regarded as a normal working state). At this time, the user can use the searchlight according to their own needs, and can adjust it freely within the brightness range of 0% to 100%.

[0057] When the user needs to temporarily increase the brightness of the searchlight, he can manually increase it to 100% brightness in a short time. At this time, the drone searchlight will calculate the first maximum working time that the searchlight can work at 120% brightness based on factors such as ambient temperature, and push it to the user. The user can work at 120% brightness during this time period (the searchlight working state at this time can be used as a high-brightness working state). If the user controls the searchlight to work at 120% brightness, then after detecting that the working time in the first working information reaches the first maximum working time (that is, greater than or equal to the first time threshold), the searchlight will automatically drop back to the highest 100% brightness and re-evaluate the second working information after the brightness is lowered, that is, the second working temperature and the second maximum working time. After the temperature meets the condition of working at 120% brightness for a certain period of time (the user can choose), the user can choose to control the searchlight to emit light at 120% brightness again. For example, it works at least 1 minute at 120% brightness or at least a certain time (such as the first maximum working time or the first time threshold mentioned above), and / or the lamp bead temperature is lower than a certain temperature such as a second temperature threshold under a certain ambient temperature.

[0058] At the same time, when the drone searchlight module detects that its own temperature is too high, it will actively push relevant information to the drone, and the user end will also receive a corresponding warning. At this time, the user can lower the brightness according to the prompt or let the drone searchlight autonomously lower the brightness according to the system preset.

[0059] For night flight lights, when the drone takes off at night, users can choose to turn on the night flight lights on the APP.

[0060] After choosing to turn it on, the night navigation light can be controlled to flash at a lower brightness (10%) to indicate that the night navigation light flashing function has been turned on; when the user operates the drone to take off, the night navigation light will always flash at a lower brightness (10% brightness, user-adjustable) during the take-off phase; when the night navigation light is above a flight altitude of 4.5 (user-adjustable) meters, the night navigation light is controlled to flash at a medium brightness (for example, 30% brightness, user-adjustable); when it is 50m (user-adjustable) or more from the ground or the user, the night navigation light is controlled to flash at full brightness (100% brightness). In this process, the night navigation light will actively obtain the flight altitude of the drone and / or the distance from the user, and automatically select the corresponding brightness and flashing frequency. When the drone lands at night, the night navigation light is also controlled based on the above-mentioned flight altitude and brightness.

[0061] By adopting the embodiment of the present invention, not only can the searchlight function be realized on the aircraft, but the safe use of the searchlight can also be automatically and intelligently guaranteed, and the flight safety of the aircraft can also be guaranteed.
