[0024] The charging control method of the adaptive underwater equipment wide power output wireless charging base station comprises the following steps:

[0025] Step 1, obtaining the charging power demand of the underwater equipment, and determining the charging power range of the underwater charging base station to which the charging power demand of the underwater equipment belongs; the charging power range of the underwater charging base station includes a high power range, a medium power range and a low power range; the high power range, the medium power range and the low power range are respectively determined according to the power output of the first wireless charging unit and the second wireless charging unit under different numbers of coils;

[0026] Step 2, the underwater charging base station communication control system determines whether the first wireless charging unit and the second wireless charging unit match the power demand of the underwater equipment according to the charging power range of the underwater charging base station to which the determined charging power demand of the underwater equipment belongs. If they match, the underwater equipment is controlled to align with the corresponding wireless charging unit, and the process proceeds to step 4 for charging; otherwise, a control signal is output to the rotation drive mechanism, and the process proceeds to step 3 to control and adjust the number of coils in the first wireless charging unit and the second wireless charging unit;

[0027] Step 3: Adjust the number of coils in the first wireless charging unit and the second wireless charging unit:

[0028] If the charging power requirement of the underwater equipment belongs to the high power range or the low power range, the underwater charging base station communication control system controls the rotation drive mechanism to work, pushes the fourth coil assembly into the first wireless charging unit, increases the number of coils in the first wireless charging unit, and reduces the number of coils in the second wireless charging unit;

[0029] If the charging power requirement of the underwater equipment belongs to the medium power range, the underwater charging base station communication control system controls the rotation drive mechanism to operate so that the fourth coil assembly is located in the second wireless charging unit, and the first wireless charging unit and the second wireless charging unit can be charged with equal power at the same time;

[0030] Step 4: Perform adaptive wireless charging:

[0031] The underwater equipment is aligned with the corresponding wireless charging unit, and the underwater charging base station communication control system outputs a control signal to the power regulation circuit. If two underwater equipment are charged at the same time, the power regulation circuit is controlled to turn on all coil components. If only one underwater equipment is charged, the power regulation circuit is controlled to turn on the corresponding coil component that needs to work.

[0032] During the charging process, the underwater charging base station communication control system monitors the charging status of the underwater equipment and the underwater charging base station in real time, and according to the monitoring results, controls the power regulation circuit in real time to adjust the output parameters of the first wireless charging unit or the second wireless charging unit to realize adaptive wireless charging of underwater equipment.

[0033] Furthermore, in step 1, the process of obtaining the charging power demand of the underwater equipment and determining the charging power range of the underwater charging base station to which the charging power demand of the underwater equipment belongs is as follows:

[0034] Step 1.1, the underwater equipment control system collects the remaining power, current and voltage information of the underwater equipment battery, calculates the charging power requirement of the underwater equipment based on the collected information, and sends it to the underwater charging base station communication control system;

[0035] Step 1.2: The underwater charging base station communication control system first modulates and demodulates the received underwater equipment charging power demand information, and then determines the charging power range of the underwater charging base station to which the underwater equipment charging power demand belongs:

[0036] Definition: When the first wireless charging unit or the second wireless charging unit has the least coil, the charging power that can be provided is the low-power charging standard value; when the coil is the most, the charging power that can be provided is the high-power charging standard value; when two wireless charging units are charged at the same power at the same time, the charging power that a single wireless charging unit can provide is the intermediate power charging standard value;

[0037] If the charging power demand of underwater equipment is less than the small-power charging standard value, it is considered that the charging power demand of underwater equipment belongs to the small-power range; if the charging power demand of underwater equipment is between the small-power charging standard value and the intermediate-power charging standard value, it is considered that the charging power demand of underwater equipment belongs to the medium-power range; if the charging power demand of underwater equipment is between the intermediate-power charging standard value and the high-power charging standard value, it is considered that the charging power demand of underwater equipment belongs to the high-power range.

[0038] The advantages of the present invention are:

[0039] 1. The present invention designs a first wireless charging unit and a second wireless charging unit that can charge two underwater equipment at the same time. Both units are provided with multiple layers of coils. Through the driving action of the rotating drive mechanism, the number of coil layers in the first wireless charging unit and the second wireless charging unit can be adjusted as needed to meet the multi-power charging power requirements of the underwater equipment, expand the working range of a single underwater charging base station, and improve the working capacity of a single underwater charging base station.

[0040] 2. In the present invention, the power requirement range of the underwater equipment is determined by the underwater charging base station communication control system, and the number of charging coils in the wireless charging unit is adaptively adjusted to meet the charging power requirements of the underwater equipment while avoiding unnecessary energy loss. For example, when charging at low power, only two layers of coils are used, and the coil loss is relatively small.

[0041] 3. In the present invention, the output power of the wireless charging unit is adjusted in real time by a power regulation circuit according to the charging status of the underwater equipment and the underwater charging base station. Compared with simply adjusting the number of coils through a driving mechanism, energy loss in the process of adjusting the coils is avoided, thereby improving the charging efficiency.

[0042] 4. In the present invention, the on and off of the coils in the two wireless charging units are individually controlled by multiple control switches in the power regulation circuit, and there is no mutual interference during switching, ensuring their independent working states.

A positioning groove is provided on the base to facilitate the positioning and installation of the first control cabin 305 and the second control cabin 405.

[0061] The central support shaft 6 is arranged at the center position of the cavity of the housing 2, and the top of the central support shaft 6 is connected to the housing 2 by a threaded connection. One side of the first coil turntable and one side of the third coil turntable are respectively fixedly connected to the two side walls of an annular member, which is nested on the outer wall of the central support shaft 6 and transitionally matched; the first coil turntable and the third coil turntable are located on the same plane.

[0062] Reference Figure 3-Figure 6 The rotary drive mechanism 5 is installed on the base 1 and is located on the central axis of the first control cabin 305 and the second control cabin 405. The rotary drive mechanism 5 includes a motor, a large bevel gear 501, a small bevel gear 502, a sleeve assembly 503, a threaded sleeve 504, a push rod 505, a hinge connection shaft 506 and a push handle 507. The output shaft of the motor is connected to the gear shaft of the large bevel gear 501 to drive the large bevel gear 501 to rotate, and the large bevel gear 501 is meshed with the vertically arranged small bevel gear 502 for transmission.

[0063] The sleeve assembly 503 includes a cylinder 50301, a support seat 50302 and a support rod 50303. The axis of the cylinder 50301 coincides with the axis of the support seat 50302, and the bottom of the cylinder does not contact the support seat 50302. One end of the support rod 50303 is fixed to the top surface of the support seat 50302, and the other end is fixedly connected to the outer wall of the cylinder 50301. The side wall of the cylinder is provided with an annular through hole as an annular track, and the central angle of the annular track is 60°. The support seat 50302 of the sleeve assembly 503 is fixedly connected to the base of the shell assembly by screws.

[0064] The outer wall of the threaded sleeve 504 is provided with a slider that matches the annular track on the side wall of the cylinder 50301. The slider is fixed on the outer wall of the threaded sleeve, and the slider can slide along the annular track when the threaded sleeve 504 moves.

[0065] The push rod 505 includes a rod and an annular structure, the side wall of the annular structure is fixedly connected to one end of the rod, the rod is located in the rotation plane of the annular structure, and the other end of the rod is connected to the push handle 507 through a hinge connecting shaft 506.

[0066] The push handle 507 is rotatably connected to the upper end of the hinge shaft 506 and is located above the rod of the push rod. The push handle 507 is an arc structure that matches the shape of the annular lug on the fourth coil turntable, and can wrap the outer wall of the annular lug, thereby pushing the fourth coil turntable connected to the annular lug to rotate, thereby realizing the coil position switching in the fourth coil turntable.

[0067] Reference Figure 7 The power regulation circuit 7 includes a DC power supply, a four-way control switch, a resonant capacitor and an adjustable resistor. The four-way control switches are respectively a first control switch, a second control switch, a third control switch and a fourth control switch. The DC power supply is connected to the underwater charging base station communication control system between the input end of the four-way control switch, and the output end of the four-way control switch is respectively connected to the coil input end of the first coil assembly, the second coil assembly, the third coil assembly and the fourth coil assembly, and the coil output end of the four groups of coil assemblies is connected to the resonant capacitor and the adjustable resistor in turn. The four-way control switch is connected to the four groups of coil assemblies in a one-to-one correspondence to realize the on-off control and power regulation of each group of coil assemblies.

[0068] The power regulation circuit 7 is used to realize the on and off of the coil assembly according to the switch on and off control signal output by the main control module of the underwater charging base station communication control system. When two underwater equipment with the same power demand need to be charged at the same time, the main control module of the underwater charging base station communication control system outputs four-way conduction control signals, and the four-way control switches are all turned on. When only one underwater equipment needs to be charged, the main control module of the underwater charging base station communication control system sends a control instruction to the wireless charging unit connected to the underwater equipment, and only controls the corresponding coil in the connected wireless charging unit to be turned on, while other control switches will not receive the conduction control instruction and remain in the disconnected state, ensuring that different coil assemblies can be correctly turned on or off according to the expected operating instructions.

[0069] Reference Figure 8 , the underwater charging base station communication control system 8 communicates wirelessly with the underwater equipment control system, and the underwater charging base station communication control system includes a signal demodulation and decoding module, a main control module and a monitoring module. The signal demodulation and decoding module includes a demodulation chip and a decoding algorithm mounted on the demodulation chip. The signal demodulation and decoding module is used to receive the underwater equipment charging power requirement information (transmitted in the form of electrical signals) sent by the underwater equipment control system, and decode the underwater equipment charging power requirement information to obtain the actual power value required by the underwater equipment, and determine which of the set power ranges the actual power value required by the underwater equipment belongs to, and transmit the decoded signal to the main control module.

[0070] The main control module is a microcontroller or microprocessor. The main control module can parse the received decoded signal, extract the required power, voltage and current information, and verify the validity and correctness of the signal, for example, check whether the power demand is within the support range of the device, whether the data packet is complete and complies with the protocol specification, etc., and according to the parsed data, the main control module calculates the required actual power, voltage and current; according to the charging status, temperature, safety standards and other factors of the device, adjust the charging strategy. The main control module generates a control signal for controlling the power regulation circuit 7 to adjust the output power. The control signal includes a voltage adjustment instruction and a current limit setting. The main control module generates corresponding control commands according to the standard charging protocol adopted, such as adjusting the voltage level and setting the maximum current. After judging whether the power demand of the underwater equipment is within the output power range of the underwater charging base station, the main control module outputs a charging control signal to the power regulation circuit to realize the on and off control of different coil components. The main control module can also receive the charging status of the underwater equipment sent by the monitoring module, and send a charging adjustment instruction to the power regulation circuit according to the charging status of the underwater equipment.

[0071] The monitoring module includes sensors and signal processing circuits, which are used to monitor the charging status of underwater equipment (including charging current, voltage, and charging completion status) and the stability of the charging system (current, voltage fluctuations, frequency changes, or abnormal signals, such as high temperature and abnormal current) in real time, and can upload the monitoring results to the main control module. The main control module can output corresponding control instructions based on the different monitoring results received: when the battery is fully charged, the main control module can output a stop or power reduction instruction to the power regulation circuit, and the power regulation circuit adjusts the current or voltage output by the first wireless charging unit or the second wireless charging unit, stops charging, or reduces power according to the received control instructions to avoid overcharging. When the monitoring module detects that the charging frequency is offset or unstable, it outputs a control instruction to adjust the transmission frequency to the power regulation circuit, and the power regulation circuit adjusts the transmission frequency of the first wireless charging unit or the second wireless charging unit to restore the stable charging state of the wireless charging unit. When the temperature is too high, the main control module can output a pause or shutdown control instruction. The power regulation circuit disconnects the path of the first wireless charging unit or the second wireless charging unit according to the pause or shutdown control instruction, or reduces the charging power to protect the underwater equipment battery and the underwater wireless charging base station and prevent system damage.

[0072] The wireless charging base station of the present invention cooperates with the rotation drive mechanism, the power regulation circuit and the communication control system, and combines the wireless charging transmission technology to achieve a wide power output that is adaptive to the power requirements of underwater equipment. The switching principle is described in detail below:

[0073] The switching principle of the rotating drive mechanism: the motor is used as the power source to drive the large bevel gear 501 and the small bevel gear 502 to mesh and rotate, and the annular track on the sleeve assembly 503 cooperates with the threaded sleeve 504 to make the push rod 505 fixedly connected to the threaded sleeve move in a fan-shaped trajectory. Since the push handle 507 is connected to the other end of the push rod through the hinge connection shaft 506, the push handle can rotate around the central support shaft 6. The push handle 507 pushes the annular lug on the side wall of the fourth coil turntable, thereby driving the fourth coil turntable to rotate until the fourth coil turntable is located in the installation space of the first wireless charging unit, so as to adjust the number of coils in each wireless charging unit according to the charging power requirements of the underwater equipment.

[0074] Power regulation circuit switching principle: In this embodiment, two coil combinations with two layers are designed, namely, a first coil assembly and a third coil assembly with two layers of coils, and a second coil assembly and a fourth coil assembly with three layers of coils. The underwater charging base station can charge two underwater equipment at the same time, which can be divided into two situations: one is when charging two underwater equipment with the same power, the first wireless charging unit and the second wireless charging unit are required to have 5 layers of coils; the other is when charging two underwater equipment with different power requirements, the total number of coils in the first wireless charging unit is 8 layers, and the total number of coils in the second wireless charging unit is 2 layers.

[0075] Working principle of underwater charging base station communication control system: The main communication and control process between underwater equipment and underwater charging base station is as follows: Figure 8 As shown. The sensor in the underwater equipment control system detects the remaining power, voltage, current and other information of the underwater equipment battery, completes data collection, and transmits the collected information to the information processing module of the underwater equipment for power demand calculation. The required charging power of the underwater equipment is calculated according to the preset algorithm, and converted into a communicable electrical signal in a specific coding method. The electrical signal containing the power demand of the underwater equipment is transmitted to the underwater charging base station through the communication module of the underwater equipment. The electrical signal containing the power demand of the underwater equipment enters the signal demodulation and decoding module of the underwater charging base station. The signal demodulation and decoding module processes the signal and transmits the processed signal to the main control module of the underwater charging base station. The main control module processes the received signal and sends a control signal; the control signal enters the power regulation circuit, and the main control module controls the power regulation circuit to conduct the corresponding coil assembly. The underwater charging base station communication control system monitors the charging power of the underwater equipment and the working status of the underwater charging base station in real time by setting a monitoring module, and transmits the monitoring results back to the main control module. The main control module makes corresponding power adjustments or charging status adjustments according to the monitoring results.

[0076] Reference Fig. 9 The charging control method for charging underwater equipment using the wireless charging base station of the present invention comprises the following steps:

[0077] Step 1: The underwater charging base station communication control system obtains the charging power demand of the underwater equipment and determines the charging power range of the underwater charging base station to which the charging power demand of the underwater equipment belongs. The specific process is as follows:

[0078] Step 1.1: After the underwater equipment docks, it communicates with the underwater charging base station communication control system.

[0079] The sensors in the underwater equipment control system collect information such as the remaining power, voltage and current of the underwater equipment battery, and calculate the power demand of the collected information through the information processing module of the underwater equipment to obtain the charging power demand of the underwater equipment, and convert the charging power demand of the underwater equipment into a communicative electrical signal in a specific coding method, and transmit the electrical signal containing the charging power demand of the underwater equipment to the underwater charging base station communication control system through the communication module of the underwater equipment.

[0080] Step 1.2, the signal demodulation and decoding module of the underwater charging base station communication control system receives the electrical signal containing the charging power demand of the underwater equipment, and modulates the electrical signal into a form suitable for transmission (such as amplitude modulation, frequency modulation, etc.) to reduce interference and loss during the transmission process. During the adjustment process, the filter is first used to remove the noise and unnecessary frequencies in the signal, and the signal strength is enhanced through the amplifier to ensure that the signal does not attenuate too much during the transmission process; the gain control is adjusted as needed to adapt to different transmission and reception conditions; the impedance is adjusted through the matching network to ensure effective transmission between the signal source and the load. Then the adjusted signal is decoded, useful data is extracted, errors in the signal are detected and corrected, and the reliability of the data is improved. The filter is used to remove high-frequency noise or other interference in the decoded signal to obtain a clear output signal to ensure the accuracy of the signal during transmission and reception.

[0081] The signal processed by the signal demodulation and decoding module of the underwater charging base station communication control system is transmitted to the main control module of the underwater charging base station communication control system, and the main control module of the underwater charging base station communication control system determines the charging power demand of the underwater equipment. In this embodiment, the charging power that can be provided by the 2-layer coil is the low-power charging standard value, the charging power that can be provided by the 5-layer coil is the medium-power charging standard value, and the charging power that can be provided by the 8-layer coil is the high-power charging standard value.

[0082] If the charging power demand of the underwater equipment is less than the low-power charging standard value, it is determined that the charging power demand of the underwater equipment is in the low-power range, and the coil in the second wireless charging unit needs to be adjusted to 2 layers; if the charging power demand of the underwater equipment is between the low-power charging standard value and the medium-power standard value, it is determined that the charging power demand of the underwater equipment is in the medium-power range, and the coils in the first wireless charging unit and the second wireless charging unit need to be adjusted to 5 layers; if the charging power demand of the underwater equipment is between the medium-power charging standard value and the high-power charging standard value, it is determined that the charging power demand of the underwater equipment is in the high-power range, and the coil in the first wireless charging unit needs to be adjusted to 8 layers.

[0083] Step 2: The main control module of the underwater charging base station communication control system determines whether the two wireless charging units on the current underwater charging base station match the charging power requirements of the underwater equipment according to the rechargeable power range of the underwater charging base station to which the charging power requirements of the underwater equipment belong. If so, the underwater equipment is controlled to align with the corresponding wireless charging unit, and the process goes to step 4 for charging; otherwise, a control signal is output to the rotation drive mechanism, and the process goes to step 3 to control and adjust the number of coils in the first wireless charging unit and the second wireless charging unit.

[0084] Step 3: Adjust the number of coils in the first wireless charging unit and the second wireless charging unit.

[0085] If the charging power demand of the underwater equipment is in the high-power range or the low-power range, the main control module of the underwater charging base station communication control system sends a command to the motor of the rotary drive mechanism, and the driving motor drives the large bevel gear to rotate. The large bevel gear transmits the motor driving force to the small bevel gear, driving the threaded sleeve fixedly connected to the gear shaft of the small bevel gear to rotate, and the slider on the threaded sleeve slides on the annular track of the sleeve assembly, thereby driving the push rod connected to the slider to rotate in the plane, and the push handle installed on the push rod pushes the fourth coil turntable to rotate around the central support shaft until the fourth coil turntable is parallel to the bottom of the second coil turntable in the first wireless charging unit, so that the number of coils in the first wireless charging unit is increased to 8 layers, and the number of coils in the second wireless charging unit is reduced to 2 layers, so that the first wireless charging unit and the second wireless charging unit can charge an underwater equipment with high power demand and a small power demand at the same time. Fig.10 As shown in a.

[0086] If the charging power demand of the underwater equipment is in the medium power range, the main control module of the underwater charging base station communication control system sends a command to the motor, driving the motor to drive the large bevel gear to rotate in the opposite direction. The large bevel gear transmits the rotation of the motor to the small bevel gear, driving the threaded sleeve fixedly connected to the gear shaft of the small bevel gear to rotate, and the slider on the threaded sleeve slides on the annular track of the sleeve assembly, thereby driving the push rod connected to the slider to rotate in the plane. The push handle installed on the push rod pushes the fourth coil turntable in the opposite direction to rotate around the central support axis until the fourth coil turntable returns to the installation space of the second wireless charging unit and is located parallel to the bottom of the third coil turntable. At this time, the number of coils in the first wireless charging unit and the second wireless charging unit are both 5 layers, which can charge two underwater equipment with medium power requirements at the same time. Fig.10 After adjustment, the main control module controls the underwater equipment to dock with the corresponding wireless charging unit and enters step 4.

[0087] Step 4, adaptive wireless charging.

[0088] After the underwater equipment is aligned with the corresponding wireless charging unit, the main control module of the underwater charging base station communication control system outputs a control signal to the power regulation circuit. If two underwater equipment are charged at the same time, all control switches in the power regulation circuit are controlled to be turned on. If only one underwater equipment is charged, the control switch in the power regulation circuit and connected to the coil in the corresponding wireless charging unit is controlled to be turned on, and the coil connected to the control switch starts to work to charge the underwater equipment.

[0089] During the charging process, the charging status of the underwater equipment and the working status of the underwater charging base station are also monitored. The specific process is as follows:

[0090] The monitoring module of the underwater charging base station communication control system monitors the charging status of the underwater equipment (including charging current, voltage, and charging completion status) and the stability of the charging system (current, voltage fluctuations, frequency changes, or abnormal signals, such as high temperature, abnormal current) in real time, and uploads the monitoring results to the main control module. The main control module outputs corresponding control instructions based on the received monitoring results: when the battery of the underwater equipment is full, the main control module sends a control signal to the power regulation circuit to stop or reduce power output. The power regulation circuit adjusts the current or voltage output, stops charging or reduces power output to prevent overcharging; when the monitoring module detects that the charging frequency is offset or unstable, the main control module outputs a transmission frequency adjustment control instruction to the power regulation circuit, and the power regulation circuit changes the transmission frequency to restore a stable charging state; when the monitoring module detects that the charging temperature is too high, the main control module sends a charging suspension instruction to the power regulation circuit, and the power regulation circuit suspends or reduces the charging power to protect the battery and the charging system.

[0091] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should be included in the protection scope of the present invention.
