At present, drone technology has been widely used in film and television shooting, flight performances, express delivery, news reporting, agricultural plant protection, disaster relief, field monitoring, biological monitoring, surveying and mapping, power inspection and other work fields.

[0003] As the number of drones and the frequency of use increase, the demand for battery charging is also increasing, and issues such as battery management and charging safety have also put forward higher requirements. Existing battery charging cabinets are generally equipped with independent power supplies, which match fixed charging modules to charge fixed models of batteries.

[0004] Combining the characteristics and usage of current battery charging cabinets, the following disadvantages are reflected:

[0005] (1) Each charging module is equipped with an independent power supply, the effective working time per day is short, and the power utilization rate is not high.

[0006] (2) One battery usually corresponds to one charging module, the module utilization rate is too low and multiple modules need to be purchased to meet the needs of the model.

[0007] (3) Some new aircraft models do not yet have matching battery charging modules, resulting in the new aircraft still being unable to be charged using existing charging cabinet products.

[0008] (4) Batteries are flammable and explosive items, and they are frequently charged, which leads to very high safety requirements. Especially when charging is not done on site, it is very easy to cause a fire and result in property loss.

[0035] 1. The overall structure of the UAV battery pack intelligent management cabinet device, especially the combined design of the pull-out box body, the detachable installation assembly frame and the fan-shaped charging cabinet, can be designed according to the different models of UAV rechargeable batteries, so that even if a new battery model appears, it can be replaced without changing the entire overall structure. Only a pull-out box body that meets the charging requirements of the new battery model needs to be customized to meet the charging requirements of the new battery model; in addition, the fan-shaped charging cabinet and the detachable installation assembly are assembled in a separate manner, which can reduce the probability of fire caused by lithium batteries or lithium batteries spontaneously combusting. In addition, it is also convenient to replace the pull-out box body, thereby improving the utilization rate of UAV lithium batteries, that is, one UAV lithium battery can be shared by multiple lithium batteries, and there is no need to repeatedly configure UAV lithium batteries.

[0036] 2. The design of the thermometer, hygrostat and spark monitor can timely monitor the charging status of the drone batteries in each pull-out box, so that the drone batteries can be charged in a safe and suitable environment, further improving the intelligent management of battery charging. In addition, because the actual space occupied by the thermometer and hygrostat is large, in order to reduce the space occupancy rate of the pull-out box and the fan-shaped frame structure, the thermometer and hygrostat adopt a separate design, which also improves the detection of temperature and humidity without changing or expanding the pull-out box structure.

[0037] 3. The fan-shaped structure design can shorten the connection distance between UAV lithium batteries and UAV lithium batteries. At the same time, the design of the turntable mechanism can further shorten the connection distance between UAV lithium batteries and UAV lithium batteries.

[0038] 4. The design of the solar charging mechanism can enable the drone battery pack intelligent management cabinet to charge the drone even in the wilderness where no external power supply is available, thereby improving the battery life of the drone and enabling the drone to continue to complete its operations.

[0039] 5. The intelligent touch interactive screen can interact with the staff to show the charging status of the battery in real time.

[0040] 6. The control system can perform a cell health assessment on each battery cell in the battery pack based on the actual measured temperature of each battery cell.

[0041] 7. Training and application of battery status management models, so that the trained battery status management model can be used to timely determine the status information used to describe whether the battery is abnormal and the adjustment information that needs to be processed for the health of a corresponding battery cell in the battery, and then the battery charging condition can be adjusted according to the adjustment information.

[0042] 8. After the battery status management model has been used for a period of time, in order to improve the accuracy rate, the trained battery status management model will be regularly retrained online in real time using the latest historical evaluation data.

[0043] 9. Under the control of the control system with the help of the control topology power switch, the UAV lithium battery can automatically select the UAV adapter that matches the UAV lithium battery for charging. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail with reference to the drawings as follows:

[0053] Example:

[0054] First, as Figures 1 to 5 As shown, the present invention provides a drone battery management device, comprising:

[0055] The fan-shaped charging cabinet 1 includes a plurality of charging cabinet structures for storing drone adapters, and a power topology control switch and a power supply for powering the drone lithium battery are also provided in the charging cabinet structure; specifically, each drone adapter is placed in a corresponding charging cabinet structure, and a side wall for storing the drone adapter is provided with an adapter port connected to the drone adapter;

[0056] The fan-shaped mounting assembly frame 2 is rotatably mounted on the fan-shaped charging cabinet 1 and is provided with a plurality of fan-shaped frame structures 21;

[0057] The pull-out box body 3 is slidably arranged in the fan-shaped frame structure 21, and is provided with an active charging area for charging the lithium battery of the drone. The side wall is provided with a charging port for plugging the charging connector of the lithium battery of the drone. The charging port is electrically connected to the power supply, so that when the lithium battery of the drone needs to be charged, the lithium battery of the corresponding drone can be charged through the charging port; the power topology control switch is connected between each adapter port and each charging port, and is used to control the connection and disconnection of the adapter port and the corresponding charging port; the power topology control switch is also electrically connected to the external power supply;

[0058] The monitoring component is arranged in the fan-shaped frame structure 21 to monitor the charging condition in the pull-out box body 3; the monitoring component includes a detection probe and a monitoring body, and the detection probes are respectively arranged in the fan-shaped frame structure 21 and respectively placed in the corresponding pull-out box body 3;

[0059] The control system is arranged in the control cavity cabinet in the fan-shaped charging cabinet 1. The control system is electrically connected to the monitoring component, the power topology control switch and the power supply source, so as to monitor the charging condition in the pull-out box body 3 in real time through the monitoring component, select an appropriate drone adapter for the drone lithium battery through the power topology control switch, and control the power supply source to power the drone lithium battery.

[0060] See also Figure 1 As an embodiment, the pull-out box body 3 of the present application is a box body structure with an end cover at the front end, and notches at the top and the rear end; a switch lock is provided at the end cover, and the switch lock includes at least a fingerprint lock, a voice-controlled lock or a face recognition lock.

[0061] As an embodiment, the end surface of the fan-shaped frame structure 21 of the present application facing the fan-shaped charging cabinet 1 may also be provided with an air outlet port, and a hot and cold air blower is provided at the air outlet port to extract the hot air from each pull-out box body 3 to play a heat dissipation role. A spacing area is provided between the fan-shaped charging cabinet 1 and the fan-shaped mounting assembly frame 2, and a ventilation duct may be provided in the spacing area.

[0062] Specifically, the active charging area runs through the bottom of the pull-out box 3 and is compatible with the structure of the UAV lithium battery. At the same time, since the active charging area can run through the bottom of the pull-out box 3, the charging area can not only reduce weight but also dissipate heat. In practical applications, the design of the pull-out box 3 can customize the corresponding pull-out box 3 according to the external structure of the new UAV battery without replacing the entire UAV battery pack intelligent management cabinet device. Any pull-out box 3 can be replaced or added at will, which not only solves the problem that one battery usually corresponds to only one charging module in the prior art, and the modular fixed design makes the utilization rate of the module too low and needs to set up multiple corresponding charging modules or even the entire cabinet to meet the model requirements, but the pull-out detachable box structure of the present application can be based on the model requirements of the UAV lithium battery without changing the entire cabinet structure, and only the pull-out box 3 can be changed, which can improve the utilization rate and use rate of the UAV battery pack intelligent management cabinet device, reduce the use cost, and increase the service life. In addition, the modular design of the pull-out box body 3 of the present application makes it possible to solve the problem of lithium batteries and battery mismatch in new models by replacing or adding a pull-out box body 3 installed in the cabinet with a pull-out box body 3 that can match the new battery. This can solve the problem that some new models still cannot be charged through existing charging cabinet products due to the lack of matching battery charging modules.

[0063] See also Figure 3 and Figure 4 As an embodiment, the power supply of the present application includes a solar charging mechanism 4 and a battery. The solar charging mechanism 4 includes a solar panel and a mounting frame arranged on a fan-shaped charging cabinet 1 or a fan-shaped mounting frame 2. The solar panel is tilted on the mounting frame. The solar panel is electrically connected to the control system and the battery so that the battery can be charged through the solar panel under the control of the control system.

[0064] See also Figure 1 and Figure 4 As an embodiment, the drone battery management device of the present application also includes a shielding plate 5, one end of the shielding plate 5 is connected to the upper part of the fan-shaped mounting assembly frame 2, and the other end is slidably connected to the upper end of the fan-shaped charging cabinet 1. The shielding plate 5 is electrically connected to the control system so that the shielding plate 5 can be folded or unfolded under the control of the control system; it is detachably arranged in the spacing area at the top of the fan-shaped charging cabinet 1 and the fan-shaped mounting assembly frame 2 to block ultraviolet rays and rain.

[0065] The detection probe of the present application is a detection probe for a thermometer and a hygrostat. The detection probes of the thermometer and the hygrostat are inside the fan-shaped frame structure 21 and are used to monitor the charging conditions inside the fan-shaped frame structure 21. The thermometer and the hygrostat are electrically connected to the control system respectively.

[0066] Specifically, the detection probes corresponding to the thermometer and hygrostat are placed at the set positions of each fan-shaped frame structure 21 to detect the temperature and humidity of the drone lithium battery when charging in the pull-out box body 3 corresponding to the fan-shaped frame structure 21. The monitoring bodies corresponding to the thermometer and hygrostat are placed in the fan-shaped frame structure 21 specified in the fan-shaped installation assembly. The temperature monitoring bodies corresponding to multiple thermometers can be integrated into one, and the humidity monitoring bodies corresponding to multiple hygrostats can be integrated into one. The probes corresponding to the thermometer and hygrostat are connected to their corresponding monitoring bodies in a detachable manner. The monitoring bodies corresponding to the thermometer and hygrostat are electrically connected to the control system. The control system obtains the temperature value sent by the monitoring body corresponding to the thermometer and the humidity value sent by the monitoring body corresponding to the hygrostat in real time. For the temperature value, if it is determined that the temperature value is higher than or equal to the temperature threshold, the hot and cold air blower is started to extract the hot air in the corresponding pull-out box body 3, so that the humidity value in the pull-out box body 3 used is kept within the set temperature range. If it is determined that the temperature value is lower than the temperature threshold, the hot and cold air blowers are started to blow hot air into the corresponding pull-out box body 3, so that the temperature value in the pull-out box body 3 used is kept within the set temperature range. For the humidity value, if it is determined that the humidity value is higher than or equal to the humidity threshold, the dehumidification function of the hot and cold air blowers is started to extract the moisture in the corresponding pull-out box body 3, so that the humidity value in the pull-out box body 3 used is kept within the set humidity range.

[0067] As an embodiment, each pull-out box body 3 is connected to a voltage and current measuring instrument for measuring the battery, and is wirelessly connected to the control system so that the control system can obtain the voltage and current of the battery cells in the battery. When it is determined that the battery needs to be tested for health, it is detected whether the charging time of each battery cell in the battery exceeds the set time threshold. If the time threshold is exceeded, each battery in the battery pack is discharged to a zero-power state, and then the battery is charged. During the charging process, it is detected whether the voltage of each battery cell in the battery is within the maintenance voltage interval belonging to the maintenance state. If they are all within the maintenance voltage range, it is determined that the battery is charged in the maintenance state. If not, the voltage of the corresponding battery cell is adjusted to the first voltage range corresponding to the maintenance range. The battery voltage that is not in the maintenance state can be a high-power state or a low-power state. Regardless of whether it is a high-voltage state or a low-voltage state, the corresponding battery cell is adjusted to the maintenance state. If the time threshold is not exceeded, it is determined whether the battery is in a fully charged state. If not, the battery is charged to a fully charged state.

[0068] As an embodiment, the drone battery management device of the present application also includes an intelligent touch interactive screen, which is arranged on the fan-shaped installation assembly frame 2 or the fan-shaped charging cabinet 1 and is electrically connected to the control system, so as to realize the charging management of the drone battery through the intelligent touch interactive screen based on the control system. The intelligent touch interactive screen is used to display the charging status of the lithium battery connected to the drone lithium battery in each pull-out box body 3 and the corresponding drone battery model. The charging status can include the current charging lithium battery meter charging time, estimated full time, estimated time left to be full, the battery temperature and humidity of the corresponding pull-out box body 3 during the current charging, and the battery SN code, battery cycle number and battery life of the battery being charged. In addition, the intelligent touch interactive screen will also display the QR code corresponding to the door lock of each pull-out box body 3. The user can obtain the verification code corresponding to opening the door lock of the pull-out box body 3 through the QR code. If the verification code is correct, the pull-out box body 3 door is controlled to open.

[0069] As an embodiment, the drone battery management equipment of the present application also includes a fire extinguishing nozzle, an electric spark monitor, a solenoid valve and a dry powder generating tank. The fire extinguishing nozzle is installed on the fire extinguishing interface in the fan-shaped frame structure 21, the solenoid valve and the dry powder generating tank are arranged in the pull-out box body 3, and the solenoid valve is connected to the fire extinguishing interface through a fire extinguishing pipe; the electric spark monitor is installed in the fan-shaped frame structure 21, the solenoid valve and the dry powder generating tank are electrically connected to the control system respectively, and the electric spark monitor is connected to the control system through wireless communication.

[0070] Specifically, the fire extinguishing nozzle is installed in the fire extinguishing interface reserved on the small end face of the fan-shaped frame structure 21 corresponding to each pull-out box body 3. The fire extinguishing interface is electrically connected to the solenoid valve through a fire extinguishing pipe in a detachable manner. The solenoid valve is connected to both the dry powder generating tank and the control system. The solenoid valve and the dry powder generating tank can be placed in the pull-out box body 3 specified in the inner pull-out box body 3; the spark monitor is installed in the fan-shaped frame structure 21 corresponding to each pull-out box body 3, and is used to monitor whether there is an electric spark that causes a fire in the pull-out box body 3. The spark monitor is connected to the control system through wireless communication. When the spark monitor detects a spark signal in the corresponding pull-out box body 3, it sends a danger signal indicating the presence of an electric spark to the control system. When the control system receives the danger signal, it controls the solenoid valve to open and the dry powder generating tank to start. At this time, the dry powder generated by the dry powder generating tank is sprayed into the space where the pull-out box body 3 to which the danger signal belongs is located along the fire extinguishing pipe along with the gas, so as to ensure the safety of the lithium battery of the drone in the pull-out box body 3.

By setting the rotating platform mechanism 6, the fan-shaped mounting assembly 2 and / or the fan-shaped charging cabinet 1 can be driven to rotate under the push of external force, so that the staff can obtain the desired arbitrary position of the pull-out box body 3 by rotating the rotating platform mechanism 6 without having to walk around the intelligent management cabinet device.

[0074] The fan-shaped support plate 61 and the limit plate 62 of the present application are arranged in the upper and lower arc-shaped limit grooves of the fan-shaped charging cabinet 1 through the limit roller rolling, so that they can rotate on the fan-shaped charging cabinet 1 without disengagement.

[0080] Step 103, control the power topology control switch to connect the charging port to the adapter port of the drone adapter corresponding to the target adapter model, and start charging the drone lithium battery; when it is determined that the drone lithium battery matches the drone adapter and is in a connected state, if the drone lithium battery is detected to determine that the current power value required by the drone lithium battery is greater than the power stored in the battery and the solar charging mechanism 4 is in a power supply state, then execute step 104; if the current power value required by the drone lithium battery is greater than the power stored in the battery and the solar charging mechanism 4 is in a non-power supply state, then execute step 105; if the current power value required by the drone lithium battery is less than the set value of the power stored in the battery, then execute step 106;

[0081] Step 104 , turning on the first switch in the power topology control switch for indicating the connection between the solar charging mechanism 4 and the drone adapter, so as to use the solar charging mechanism 4 for power supply.

[0082] Step 105, turning on the second switch in the power topology control switch for indicating the connection between the external power source and the lithium battery of the drone, so as to use the external power source to charge the lithium battery of the drone.

[0083] Step 106, turning on the third switch in the power topology control switch for indicating the connection between the storage battery and the lithium battery of the drone, so as to use the storage battery to charge the lithium battery of the drone.

[0084] Step 107, after determining that the drone lithium battery is fully charged, control the power topology control switch to disconnect the charging port from the drone adapter corresponding to the target adapter model.

[0085] When the solar charging mechanism 4 is not supplying power, the fourth switch between the solar charging mechanism 4 and the storage battery is turned on, so that the electric energy received by the solar charging mechanism 4 is stored in the storage battery.

[0086] Specifically, after determining that the drone lithium battery has been inserted into the charging port, the implementation method for obtaining the device model of the drone lithium battery and the charging position information of the pull-out box body 3 in which it is located can be that the hardware detection program set by the control system detects the drone lithium battery that has just been inserted into the charging port to determine the device model of the drone lithium battery. Another implementation method can also be: an identifier for identifying the lithium battery model of the drone lithium battery is set on the drone lithium battery, and the identifier can be a QR code or an icon, and a camera for shooting the icon is installed in each pull-out box body 3, and the camera is electrically connected to the control system. The implementation method can be: the control system receives the image information sent by the camera, identifies the image information, and obtains the device model of the drone lithium battery in the pull-out box body to which the image information belongs.

[0087] A battery connected to the control power topology control switch is also provided in the designated charging cabinet structure. The battery is electrically connected to the solar charging mechanism. The control system is also charged in the following manner:

[0088] It can be seen that the application of the technical solution provided in this embodiment makes it possible to use the charging cabinet device to charge the lithium battery of the drone in time even when working in the wilderness and without external power supply, thereby ensuring that the drone can continue to fly in time and complete the operation.

[0089] In other embodiments, when the control system determines that it is necessary to perform a cell health assessment on the lithium battery in the corresponding pull-out box 3, it obtains the temperature of the battery cell, the battery SN code, the number of battery cycles, the battery life, the voltage and current of each cell in the battery as battery assessment data describing and measuring the battery health status, and inputs the battery assessment data into the trained battery status management model to obtain status information describing whether the battery is abnormal and adjustment information for health treatment of a corresponding cell in the battery, and the adjustment information includes adjusting the corresponding battery to be in a maintenance state, a charging state, or a discharging state. If the status information is abnormal, the voltage of the corresponding cell is adjusted according to the adjustment information until the cell is in a maintenance state. This protects the health of the cell to the greatest extent, reduces battery loss, and extends the battery life.

[0090] Among them, the training process of the trained battery status management model is as follows: multiple models of batteries are used as training objects, and for each model, the historical data corresponding to the battery cell of this model is obtained as a training sample. These historical data include temperature, battery SN code, number of battery cycles, battery life, and voltage and current of each cell in the battery. First, during training, these historical data are preprocessed, which may include noise data processing. The preprocessed training samples are input into the neural network model to obtain status information indicating whether the battery is abnormal and adjustment information that requires health treatment of a corresponding cell in the battery. It is determined whether the output status information and adjustment information are consistent with the corresponding historical status information and historical adjustment information used for comparison. If they are consistent, the number of training times is recorded as qualified. If they are inconsistent, the neural network model parameters are adjusted, and the step of inputting the preprocessed training samples into the neural network model is returned again until the number of training times is completed. If the ratio of the recorded number of qualified training times reaches a threshold, the finally trained neural network model is used as the battery status management model. If the recorded number of training times is unqualified, new training samples are re-acquired as part of the training samples and added to the original training samples. The neural network model parameters are adjusted and the neural network model is trained until the ratio of the recorded number of qualified training times reaches a threshold.

[0091] As an embodiment, in actual application, the control system obtains the temperature of the battery cell, the battery SN code, the number of battery cycles, the battery life, the voltage and current of each battery cell in the battery at intervals as battery evaluation data describing and measuring the health status of the battery, and inputs the battery evaluation data into a trained battery status management model to obtain status information indicating whether the battery is abnormal and adjustment information that needs to be health-treated for a corresponding battery cell in the battery;

[0092] At the same time, the control system obtains the temperature inside the pull-out box 3. If the temperature is within the set healthy temperature range, it determines whether the battery connected to the drone lithium battery is in a fully discharged battery. If so, the actual charging time required for the battery connected to the drone lithium battery from the initial charging to full charging is recorded, and the standard charging time corresponding to the battery model is obtained from the preset association relationship between the battery model and the standard charging time. If the difference between the charging time and the standard charging time is greater than the charging threshold, it is considered that the battery is in an abnormally healthy state. Otherwise, it is considered that the battery is in a normal healthy state. If the health state output by the battery status management model is consistent with the current When the health status determined before is inconsistent, the actual battery evaluation data before the current moment is obtained as new training data, and the status information and adjustment information of the corresponding historical output are used as adjustment standards, so as to train the current battery status management model based on the adjustment standards and training data. After determining that the result output by the trained battery status management model reaches the threshold value of the compliance rate with the adjustment standards, the new battery status management model is used as the final battery status management model. In this way, the battery status management model can be repaired in time to improve the accuracy of the battery status management model, thereby protecting the health of the battery cell to the greatest extent, reducing battery loss, and extending the battery life.

[0093] In a third aspect, the present application also provides a drone battery system, comprising the drone battery management device, remote monitoring platform and communication module described in the above-mentioned first aspect embodiment, and the remote monitoring platform is electrically connected to the control system through the communication module.

[0094] It can be seen that, compared with the prior art, the design of multiple pull-out boxes 3, detachable fan-shaped mounting frame 2 and fan-shaped charging cabinet 1 in the drone battery pack intelligent management cabinet device of the present application can replace any uncommon pull-out box 3 with a new type of drone battery according to the model system of the drone lithium battery without replacing the entire drone battery pack intelligent management cabinet device. It can not only solve the problem that some new models cannot be charged through existing charging cabinet products due to the lack of matching battery charging modules, but also solve the problem that the existing drone charging cabinet working mode and performance can no longer fully meet the power production needs. It can also improve the utilization rate and use rate of the drone battery pack intelligent management cabinet device, reduce the use cost, and increase the service life. In addition, the intelligent management cabinet device for the battery pack of the drone is also equipped with a control system, a temperature meter, a humidity meter, a fire extinguishing nozzle, a solenoid valve, a dry powder generating tank and an electric spark monitoring system, so that under the control of the control system, the battery can be charged at a suitable temperature and constant humidity. At the same time, it can monitor the battery in the process of charging. Possible fire hazards can be faced, and the fire can be automatically extinguished in time to avoid further fire risks and ensure property losses. In addition, the control system can protect the health of the battery to the greatest extent, reduce battery loss, and extend the battery life by evaluating and managing the health status of the battery. It brings a good experience effect to users.
