[0003] When the drone is powered by multiple batteries, the layout of the battery compartments of the multiple batteries is not exactly the same. For example, in the above dual-battery power supply solution, the two battery compartments are arranged in a centrally symmetrical manner.

[0035] The following will describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0036] At present, most drones in related technologies are powered by multiple batteries, the most common of which are: Figure 1 The dual-battery power supply scheme shown in the figure. For factors such as weight balance and compact structure, the two batteries used in the dual-battery power supply scheme will adopt a central symmetrical layout. The left battery is equipped with four indicator lights, which are numbered 1 to 4 from top to bottom. The right battery is also equipped with four indicator lights, which are numbered 1 to 4 from bottom to top. Some of the alarm modes of the indicator lights are shown in Table 1:

[0037] Table 1 Some alarm modes of the drone battery indicator

[0038]

[0039] In actual applications, since the indicator lights of the left and right batteries are flipped, the light language displayed by the indicator lights may be ambiguous. For example, when the No. 1 and No. 2 indicators of the right battery are flashing red, it may be mistaken for the No. 3 and No. 4 indicators to be flashing red. At this time, the "charging and discharging overtemperature" anomaly may be mistaken for the "pressure difference alarm" anomaly, which will affect the user's judgment of the drone situation and thus affect the user experience.

[0040] Based on this, an embodiment of the present application provides a method for controlling a drone battery indicator light, which determines the position of the drone battery based on the position identification signal sent by the drone side and the correspondence between the position identification signal and the position, and then determines the indicator light control strategy based on the correspondence between the position and the indicator light control strategy, and finally uses the indicator light control strategy to control the indicator light to perform synchronized light language actions. The above scheme uses the indicator light control strategy to control the drone's battery indicator light to perform synchronized light language actions, so that the drone battery can adaptively adjust the indicator light control strategy according to its position, reducing the probability of light language ambiguity problems, which is conducive to improving user experience.

[0041] The following is an introduction to the control method of the battery indicator light of the above-mentioned drone. Figure 2 The present application embodiment provides a method for controlling a battery indicator light of a drone, which is applied to the battery side. The method includes:

[0042] Step S110: Acquire the position identification signal sent by the drone side;

[0043] Step S120: determining the position of the battery of the drone based on the first mapping relationship; wherein the first mapping relationship is used to characterize the corresponding relationship between the position identification signal and the position;

[0044] Step S130: determining the indicator light control strategy of the drone battery based on the second mapping relationship; wherein the second mapping relationship is used to characterize the correspondence between the position and the indicator light control strategy, the indicator light control strategy is used to characterize the correspondence between the indicator light number and the synchronous light language, and the synchronous light language is determined based on the layout of the indicator light;

[0045] Step S140: using the indicator light control strategy to control the indicator lights to execute synchronous light language actions.

[0046] It is understandable that the drone side in the above step S110 refers to the drone with a battery compartment, and the battery side refers to the drone battery. The position identification signal in step S110 refers to a signal used for position identification. It is understandable that different position identification signals can be set for different positions. Taking the dual-battery power supply solution as an example, the position identification signal can be a level signal, and the low-level signal and the high-level signal correspond to another position. The position identification signal can also be a voltage signal, and the signal within a certain voltage range corresponds to one battery position, and the signal within another voltage range corresponds to another battery position.

[0047] Of course, the position identification signal can also be other forms of signals, such as current signals, coding signals and communication signals. In addition to using voltage signals, current signals, coding signals and communication signals separately, the position identification signal can also use a mixed signal of multiple signals among voltage signals, current signals, coding signals and communication signals. The type of position identification signal can be set according to the application scenario, and can achieve the following functions: (1) The battery side can read; (2) The position identification signals corresponding to each position are different, or the battery side can identify the unique position where the battery is located based on the position identification signal. In addition, it can be understood that the battery side can obtain the position identification signal sent by the drone side through circuits, communication buses or wireless communications.

[0048] It is understandable that when the position identification signal adopts a mixed signal of multiple types of signals, the multiple types of signals can be used for position identification respectively, and the identified positions can assist each other in confirming the unique position. Of course, multiple types of signals can also be used together for position identification.

[0049] From the above introduction to the position identification signal, it can be seen that the unique position of the drone battery can be obtained according to the position identification signal, that is, there is a corresponding relationship between the position identification signal and the battery position, and this corresponding relationship is the first mapping relationship mentioned above. After the position identification signal is obtained in step S110, the position of the drone battery can be determined based on the first mapping relationship.

[0050] The above-mentioned light language refers to a series of specific flashing, color change and other visual signals displayed by the indicator light to convey the corresponding status information, warning information or other important prompts. Synchronous light language refers to the light language determined based on the layout of the indicator light. It can be understood that the light language in the relevant technology is mostly determined based on the light signal. Synchronous light language is different from the light language determination method based on the light signal in the relevant technology. Figure 1 The dual battery power supply solution shown is used as an example to introduce the synchronous light language based on the indicator light layout and the light language based on the light signal:

[0051] (1) Light language based on light signals:

[0052] The four indicator lights of the left battery are indicator lights 1 to 4 from top to bottom, and the four indicator lights of the right battery are indicator lights 1 to 4 from bottom to top. The indicator lights implement light language actions in the manner shown in Table 1 above.

[0053] (2) Synchronous light language based on indicator light layout:

[0054] The four indicator lights of the left battery can realize light language actions in the manner shown in Table 1, and since the indicator light layout of the four indicator lights of the right battery is centrally symmetrical with the four indicator lights of the left battery, the indicator lights of the right battery can be subjected to signal mapping operations to realize the synchronous light language as shown in Table 2. At this time, the light language of the right battery and the left battery presents a mirror-symmetrical relationship rather than a centrally symmetrical relationship, which is beneficial to reduce the probability of light language ambiguity problems.

[0055] The above signal mapping operation can be:

[0056] (1) Map the indicator light control signal of the indicator light No. 1 of the right battery to the indicator light No. 4 of the right battery;

[0057] (2) Mapping the indicator light control signal of the indicator light No. 2 of the right battery to the indicator light No. 3 of the right battery;

[0058] (3) Map the indicator light control signal of the indicator light No. 3 of the right battery to the indicator light No. 2 of the right battery;

[0059] (4) Map the indicator light control signal of the indicator light No. 4 of the right battery to the indicator light No. 1 of the right battery.

[0060] Take the case where both the left and right batteries have abnormal charging and discharging overtemperature as an example. Figure 3 As shown, the indicator lights 1 and 2 of the left battery are flashing red, while the indicator lights 3 and 4 of the right battery are flashing red, thus achieving light language synchronization.

[0061] Table 2 Synchronous light language of a battery in the dual battery power supply solution

[0062]

[0063] It can be understood that from the above introduction to the synchronized light language, the corresponding indicator light mapping method can be set in advance for different indicator light layouts to realize the synchronized light language, and the indicator light control strategy can be set according to the indicator light mapping method, so that the drone battery can use the indicator light control strategy to perform synchronized light language actions.

[0064] Since drones have a wide variety of application scenarios, in different application scenarios, the same position may use different position identification signals, or use different synchronous light languages ​​to meet the needs of the scenario. The flexibility of the drone battery indicator light control method in the related art is poor. Based on this, the embodiment of the present application provides the following solution;

[0065] As an optional implementation of the above-mentioned drone battery indicator light control method, the above-mentioned drone battery indicator light control method also includes: updating the first mapping relationship after receiving a first mapping relationship update instruction; and / or updating the second mapping relationship after receiving a second mapping relationship update instruction.

[0066] It can be understood that the above-mentioned mapping relationship update instruction can be sent by the drone side, and the drone side can provide the user with a platform for updating the mapping relationship. The platform can be a human-computer interaction device set on the drone, or it can be a cloud platform. The user can configure the above-mentioned first mapping relationship and the second mapping relationship through the platform.

[0067] The first mapping relationship and the second mapping relationship in the above scheme can be updated according to the mapping relationship update instruction, so that the above-mentioned drone battery indicator light control method can be applicable to more application scenarios, which is conducive to improving the adaptability and flexibility of the above-mentioned drone battery indicator light control method.

[0068] During the flight of the drone, the drone battery may have some battery failures that seriously affect the flight, such as battery connection failure. At this time, if normal light language is still used to remind the user, due to the certain distance between the drone and the user, the user may not be able to respond in time, resulting in a safety accident. Based on this, the embodiment of the present application provides the following solution:

[0069] As an optional implementation of the above-mentioned drone battery indicator light control method, the above-mentioned drone battery indicator light control method also includes: real-time monitoring of the battery fault signal of the drone battery; when the drone battery fault signal is monitored, controlling all the indicator lights of the drone battery to perform fault warning light language actions.

[0070] It is understandable that the battery fault signal refers to a fault such as a battery connection fault that will seriously affect the flight of the drone. The fault warning light action is, for example, all indicator lights flash red, or all indicator lights are always red.

[0071] When the above scheme detects a battery fault signal of the drone battery, it controls all indicator lights of the drone battery to execute fault warning light language actions, thereby making the communication of fault information simpler and more direct, which is conducive to reducing the probability of drone safety accidents caused by complex light language.

[0072] In addition, during the flight of the drone, the light intensity of the drone's environment is different. If the indicator light uses a constant brightness to display the light language, it will affect the user's recognition of the light language, resulting in a wrong judgment of the drone's battery status. Based on this, the embodiment of the present application provides the following solution:

[0073] As an optional implementation of the above-mentioned drone battery indicator light control method, the above-mentioned step S140 includes: obtaining the light intensity of the environment in which the drone battery is located; based on a third mapping relationship, determining the target brightness when the indicator light performs the corresponding light language action; wherein the third mapping relationship is used to characterize the correspondence between the light intensity of the environment in which the drone battery is located and the indicator light brightness; and using the indicator light control strategy to control the indicator light to perform the corresponding light language action at the target brightness.

[0074] It is understandable that the light intensity of the environment in which the drone battery is located can be obtained by a light intensity sensor arranged on the drone side or the battery side.

[0075] The drone battery in the above solution can adaptively adjust the brightness of the indicator light according to the light intensity of the environment, so that the light language can be clearly seen under different light intensities, reducing the probability of incorrect battery status judgment caused by unclear light language, which is conducive to improving user experience.

[0076] Based on the same inventive concept, an embodiment of the present application further provides a drone battery, the drone battery comprising:

[0077] A processor is used to execute any of the above-mentioned drone battery indicator light control methods.

[0078] See also Figure 4 Based on the same inventive concept, the embodiment of the present application also provides a drone battery light language synchronization system 200, which includes: a position identification signal generation module 210 arranged on the drone side and a plurality of drone batteries 220 arranged on the battery side, wherein:

[0079] A position identification signal generating module 210 is used to generate a position identification signal and send the position identification signal to a corresponding drone battery 220;

[0080] A processor is provided in the drone battery 220, and the processors in the multiple drone batteries 220 respectively execute any of the above-mentioned drone battery indicator light control methods to achieve light language synchronization of the multiple drone batteries.

[0081] As an optional implementation of the above-mentioned drone battery light language synchronization system, the above-mentioned system also includes:

[0082] A mapping relationship update module is arranged on the UAV side, and is used to receive update information of the first mapping relationship and / or the second mapping relationship, generate a first mapping relationship update instruction and / or a second mapping relationship update instruction based on the update information, and send the first mapping relationship update instruction and / or the second mapping relationship update instruction to the battery side.

[0083] It is understandable that the mapping relationship update module can obtain the mapping relationship update information through the human-computer interaction device deployed on the drone, or through the cloud platform. The user can configure the first mapping relationship and the second mapping relationship on the human-computer interaction device deployed on the drone or the cloud platform.

[0084] As an optional implementation of the above-mentioned drone battery light language synchronization system, the above-mentioned system also includes: a fault alarm module, which is used to monitor the battery fault signal of the drone battery in real time, and when the drone battery fault signal is detected, control all indicator lights of the drone battery to perform fault alarm light language actions.

[0085] As an optional implementation of the above-mentioned drone battery light language synchronization system, the above-mentioned system also includes: an indicator light brightness determination module, which is arranged in the drone battery and is used to obtain the light intensity of the environment in which the drone battery is located; based on a third mapping relationship, determining the target brightness of the indicator light when the indicator light performs the corresponding light language action; wherein the third mapping relationship is used to characterize the correspondence between the light intensity of the environment in which the drone battery is located and the indicator light brightness.

[0086] It can be understood that the position identification signal generated by the above-mentioned position identification signal generating module 210 may include a voltage signal, a current signal, a coding signal and a communication signal. The position identification signal may be one of the voltage signal, the current signal, the coding signal and the communication signal, or a mixed signal of at least two of the voltage signal, the current signal, the coding signal and the communication signal.

[0087] Below Figure 3 In the dual battery power supply solution shown, the implementation method of the bin identification signal generating module 210 when the bin identification signal is a voltage signal is introduced as follows:

[0088] See also Figure 5 An embodiment of the present application provides a voltage divider circuit to generate a position identification signal. The voltage divider circuit divides the 3.3V input voltage SMCU_3V3, and the two output signals ADC_IN_1 and ADC_IN_2 of the voltage divider circuit are sent to the battery side through the position identification pins respectively set in the two battery compartments.

[0089] See also Figure 6The voltage signal generated by the voltage divider circuit is input to the battery side through the position identification pin, and then input to the processor arranged on the battery side through a protection circuit and a voltage follower, wherein:

[0090] The protection circuit, including diodes D11 and D44 and resistor R145, works together to protect the circuit from overvoltage conditions;

[0091] The voltage follower includes an operational amplifier TLV333IDBVR, wherein the non-inverting input terminal IN+ of the operational amplifier is connected to the position identification signal, and the output terminal OUT is connected to the inverting input terminal IN- to form a negative feedback loop, thereby realizing voltage following and isolating the external voltage from the processor.

[0092] It can be understood that the output terminal OUT of the operational amplifier outputs the position identification signal to the PA1 pin of the processor, so that the processor obtains the position identification signal.

[0093] In addition, it is understood that the operational amplifier can be powered by dual power supplies (i.e. Figure 6 The power supply can be used to supply power to the operational amplifier through the VDD terminal of the operational amplifier. A current limiting resistor (i.e. Figure 6 The resistor R83 and the resistor R101 shown in FIG. 1 and the filter capacitor (ie Figure 6 Capacitor C87 and capacitor C91 shown in FIG.

[0094] It can be understood that the above voltage divider circuit is for a dual-battery power supply solution. Of course, different voltage divider circuits can be used for power supply solutions with different numbers of batteries. Taking the scenario where the drone is powered by 8 batteries as an example, if the position identification signal is a voltage signal, the position identification signal of each position is shown in Table 3.

[0095] Table 3 Position identification signals of each position in the scenario of eight batteries supplying power

[0096] Position identification signals Position No. ADCIN≤0.4V 1 0.4<ADCIN≤0.8V 2 0.8<ADCIN≤1.2V 3 1.2<ADCIN≤1.6V 4 1.6<ADCIN≤2.0V 5 2.0<ADCIN≤2.4V 6 2.4<ADCIN≤2.8V 7 2.8V <ADCIN 8

[0097] It is understandable that, in addition to the voltage signal used alone as the position identification signal, signals such as PWM wave, serial port signal, etc. can also be used alone as the position identification signal. Of course, a mixed signal of multiple signals such as voltage signal, current signal, coding signal and communication signal can also be used as the position identification signal.
