Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, and in particular discloses a multi-functional emergency lighting UAV system and its collaborative control method. Background Technology

[0002] In emergency scenarios such as emergency rescue and nighttime operations, emergency lighting is a core requirement for ensuring operational safety and improving rescue efficiency. Drones, with their unique advantages of flexible deployment, wide coverage, and lack of terrain limitations, have become an important tool in the field of emergency lighting. However, current technologies related to emergency lighting drones in the industry still suffer from many common shortcomings, including poor coordination of power supply systems, insufficient adaptability of power supply modes, and a lack of scientifically sound control logic and parameter systems. This makes it difficult to balance flight stability, lighting continuity, and reliable power supply in practical applications, thus failing to fully adapt to the diverse needs of various emergency scenarios. Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this invention is to provide a multifunctional emergency lighting drone system and its collaborative control method.

[0004] To achieve the above objectives, the present invention provides a multifunctional emergency lighting drone system, comprising a ground power supply base station and a drone body. The ground power supply base station has a built-in power distribution system and a wireless power transmission module. The input end of the power distribution system is electrically connected to an external mains power supply, and the output end of the power distribution system is electrically connected to the wireless power transmission module. The drone body includes a flight frame, a power storage module, a flight system module, a lighting module, and a wireless power receiving module. The power storage module and the wireless power receiving module provide power to the flight system module and the lighting module. The wireless power receiving module and the wireless power transmission module establish a contactless power connection through a wireless power transmission link. The power storage module is electrically connected to the flight system module, the lighting module, and the wireless power receiving module, respectively. The wireless power receiving module is used to receive power transmitted from the ground power supply base station, thereby replenishing power to the flight system module, the lighting module, and the power storage module. The power distribution system has a built-in power allocation algorithm that collects and analyzes the drone's flight load power, the power status of the flight system modules, the load power of the lighting module, the power status of the lighting module, and the power status of the energy storage module in real time. It dynamically switches between charging priority mode, lighting priority mode, balanced power supply mode, and normal power supply mode to adjust the output power and energy distribution ratio of the wireless energy transmission module.

[0005] The ground-based power supply base station integrates a power distribution system and a wireless power transmission module. After connecting to external mains power, the power distribution system transmits electricity to the wireless power transmission module. The UAV's wireless power receiving module establishes a contactless power connection with the wireless power transmission module via a wireless power transmission link, receiving the power transmitted from the ground to replenish the flight system module, lighting module, and energy storage module. The energy storage module is electrically connected to the flight system module, lighting module, and wireless power receiving module, working together with the wireless power receiving module to provide power to the flight system module and lighting module. The power distribution system's built-in power allocation algorithm collects and analyzes in real time the UAV's flight load power, the power status of the flight system modules, the load power of the lighting module, and the lighting... The module's power status and the energy storage module's power status dynamically switch between charging priority mode, lighting priority mode, balanced power supply mode, and normal power supply mode, adjusting the output power and energy distribution ratio of the wireless energy transmitting module. Its beneficial effects include achieving stable power transmission and multi-module power supply assurance through a non-contact wireless power supply design between the ground power base station and the UAV body. Combined with the multi-mode dynamic switching function of the power distribution algorithm, power can be rationally allocated according to the real-time operating status of each module, improving the targeting and efficiency of power supply and ensuring the stable operation of the flight system module and lighting module. Simultaneously, the collaborative power supply design of the energy storage module and the wireless energy receiving module further enhances the system's power supply reliability and strengthens its practicality and adaptability.

[0006] The charging priority mode prioritizes the wireless energy receiving module to replenish the energy storage module. The charging priority mode is triggered when the remaining power of the energy storage module is below a first preset power threshold, the remaining power of the flight system module is not below a safe flight threshold, no emergency lighting trigger signal is received from the ground control terminal, and the lighting module is not operational. The power allocation algorithm adjusts the output power of the wireless energy transmitting module to a first preset power range based on the trigger conditions, prioritizing the delivery of energy within that range to the energy storage module until the remaining power of the energy storage module reaches a second preset threshold. When the remaining power of the energy storage module reaches the second preset threshold, it automatically exits the charging priority mode and switches to normal power supply mode.

[0007] When the remaining power of the energy storage module is lower than the first preset power threshold, and the remaining power of the flight system module is not lower than the safe flight threshold, no emergency lighting trigger signal is received from the ground control terminal, and the lighting module is not in working condition, the charging priority mode is triggered. At this time, the wireless energy receiving module prioritizes replenishing the energy storage module. The power allocation algorithm adjusts the output power of the wireless energy transmitting module to the first preset power range according to the trigger condition, and prioritizes the delivery of the energy within this range to the energy storage module, continuously replenishing the energy storage module until its remaining power reaches the second preset threshold. When the remaining power of the energy storage module reaches the second preset threshold, it automatically exits the charging priority mode and switches to the normal power supply mode. Its beneficial effect is that by accurately activating the charging priority mode through clear trigger conditions, priority is given to replenishing the energy storage module's power, while also taking into account the safe flight requirements of the flight system module. It avoids the waste of energy when the emergency lighting requirement is not triggered or the lighting module is not working. Through power adjustment and automatic mode switching, it achieves reasonable energy distribution, improves the charging efficiency of the energy storage module, ensures that the energy storage module has sufficient energy reserves, provides a guarantee for backup power supply in subsequent emergency scenarios, and further improves the rationality and reliability of the entire system's power supply.

[0008] The lighting priority mode prioritizes the wireless power receiving module to replenish the lighting module's power. The triggering condition for this mode is that the UAV receives an emergency lighting trigger signal from the ground control terminal, and the lighting module's power level is below a first preset power threshold, while the flight system module's remaining power level is not below a safe flight threshold. The power allocation algorithm adjusts the output power of the wireless power transmitting module to a first preset power range based on the triggering condition, prioritizing the delivery of power within that range to the lighting module until the lighting module's remaining power level reaches a second preset threshold. When the lighting module's remaining power level reaches the second preset threshold or the emergency lighting trigger signal is canceled, the system automatically exits the lighting priority mode and switches to normal power supply mode.

[0009] When the UAV receives an emergency lighting trigger signal from the ground control terminal, and the lighting module's power level is below a first preset power threshold while the flight system module's remaining power level is not below a safe flight threshold, the lighting priority mode is triggered. In this mode, the wireless power receiving module prioritizes replenishing power to the lighting module. Based on this trigger condition, the power allocation algorithm adjusts the output power of the wireless power transmitting module to a first preset power range and prioritizes supplying power within this range to the lighting module, continuously replenishing it until its remaining power level reaches a second preset threshold. When the lighting module's remaining power level reaches the second preset threshold or the emergency lighting trigger signal is canceled, the system automatically exits the lighting priority mode and switches to normal power supply mode. The beneficial effects are that precise trigger conditions ensure the timely activation of the lighting priority mode in emergency lighting scenarios, prioritizing the replenishment of the lighting module's power to meet core emergency lighting needs, while also considering the safe flight threshold requirements of the flight system module, avoiding flight safety hazards caused by priority power supply. Through power adjustment and automatic mode switching, precise power allocation in emergency scenarios is achieved, improving the power supply efficiency and continuity of the lighting module, ensuring the smooth operation of emergency lighting missions, and further enhancing the emergency response capability and practical reliability of the entire system.

[0010] The balanced power supply mode involves the wireless power receiving module replenishing power to the flight system module, lighting module, and energy storage module according to the rated power ratio of each module. The balanced power supply mode is triggered when the load power of the lighting module is lower than its rated power and its remaining power is higher than a first preset power threshold; the load power of the flight system module is lower than its rated power and its remaining power is higher than the first preset power threshold; the remaining power of the energy storage module is higher than the first preset power threshold; and no charging priority or lighting priority mode trigger signal is received. Based on the trigger conditions, the power allocation algorithm transmits power to the flight system module, lighting module, and energy storage module according to the rated power ratio of each module via the wireless power transmitting module. If a charging priority mode or lighting priority mode trigger signal is received during operation, the system switches to either mode. When any module experiences a load power reaching its rated power and a remaining power exceeding a second preset power threshold, the system automatically exits the balanced power supply mode and switches to the normal power supply mode.

[0011] When the load power of the lighting module is lower than its rated power and the remaining power is higher than the first preset power threshold, the load power of the flight system module is lower than its rated power and the remaining power is higher than the first preset power threshold, and the remaining power of the energy storage module is higher than the first preset power threshold, and no trigger signal for charging priority mode or lighting priority mode is received, the balanced power supply mode is triggered. At this time, the wireless power receiving module replenishes power to the three modules according to the rated power ratio of the flight system module, lighting module, and energy storage module. The power distribution algorithm, based on the above trigger conditions, transmits power to the flight system module, lighting module, and energy storage module respectively through the wireless power transmitting module according to the rated power ratio of each module. During operation, if a charging priority mode or lighting priority mode is received... Upon receiving the trigger signal, the system immediately switches to the corresponding power supply mode. When any module experiences a load power reaching its rated power or a remaining power exceeding a second preset power threshold, it automatically exits the balanced power supply mode and switches to the normal power supply mode. Its advantages lie in ensuring that the balanced power supply mode is activated only when none of the modules have an urgent power demand through precise triggering conditions. Distributing power according to the rated power ratio achieves balanced power supply to each module, avoiding energy waste caused by excessive power supply to a single module. Simultaneously, it prevents insufficient power supply to some modules from affecting operational stability. The flexible mode switching mechanism can promptly respond to emergency power demands and changes in module operating status, ensuring stable and coordinated operation of all modules and further improving the rationality, efficiency, and reliability of the entire system's power supply.

[0012] The normal power supply mode prioritizes replenishing the flight system module with power to the second preset power threshold, then replenishes the lighting module with power to the second preset power threshold, and finally replenishes the energy storage module with power to the second preset power threshold. The normal power supply mode is triggered when the charging priority mode, lighting priority mode, and balanced power supply mode are not triggered.

[0013] When the charging priority mode, lighting priority mode, and balanced power supply mode are not triggered, the normal power supply mode is activated. Power is supplied to each module sequentially according to the priority order of "flight system module → lighting module → energy storage module" until each module reaches the second preset power threshold. The beneficial effect is that, through clear priority sequencing and power replenishment standards, the stable operation of the flight system modules is ensured, the normal operation of the lighting module is guaranteed, and power resources are rationally allocated to avoid energy waste. This balances the power supply needs of each module with the stability and orderliness of system operation, further improving the rationality and practicality of the entire system's power supply and adapting to the normalized power supply needs in emergency scenarios.

[0014] The power distribution system also includes a step-up transformer module, a rectifier and filter module, a step-down voltage regulator module, and a multi-channel power distribution control unit. The input terminal of the step-up transformer module is connected to the external mains power supply to adjust the voltage level of the external mains power supply to meet the input requirements of the subsequent rectifier and filter module and step-down voltage regulator module. The input terminal of the rectifier and filter module is connected to the output terminal of the step-up transformer module to convert the boosted AC voltage into DC voltage and filter out high-frequency noise in the voltage. The input terminal of the step-down voltage regulator module is connected to the output terminal of the rectifier and filter module to step down the DC voltage to a level suitable for the working voltage of the UAV flight system module, lighting module, and energy storage module, while also implementing current limiting protection. The multi-channel power distribution control unit has the built-in power distribution algorithm to receive various load power data and status signals to realize the power distribution and dynamic switching of the power supply mode.

[0015] The power distribution system comprises a step-up transformer module, a rectifier and filter module, a step-down voltage regulator module, and a multi-channel power distribution control unit. The step-up transformer module connects to external AC power and adjusts the AC voltage level to meet the needs of subsequent modules. The rectifier and filter module converts the boosted AC voltage to DC voltage and filters out high-frequency noise. The step-down voltage regulator module reduces the DC voltage to a level suitable for the operating voltage of each module on the UAV, while also implementing current-limiting protection. The multi-channel power distribution control unit has a built-in power distribution algorithm that receives various load power data and status signals to perform power distribution and dynamic switching of power supply modes, ensuring a stable power supply. Its advantages lie in the fact that through the coordinated operation of each module, it achieves reasonable conversion and stable output of AC power, ensuring that the power supply meets the operating requirements of each module on the UAV, avoiding problems such as voltage instability and noise interference, improving power utilization efficiency, and ensuring the stability and reliability of the power supply. Furthermore, through current-limiting protection and dynamic power supply switching, it further enhances the safety and practicality of the system operation, providing strong support for the stable operation of the entire system.

[0016] The multi-channel power distribution control unit includes a power detection module, a microcontroller, and a switch control module. The power detection module is used to collect real-time data on the flight load power of the UAV, the load power of the lighting module, and the charging and discharging power of the energy storage module, and transmit the collected data to the microcontroller in real time. The microcontroller has a pre-stored power distribution algorithm, analyzes and processes the received data, and generates mode switching instructions and power distribution instructions based on the power status of the energy storage module, flight system module, and lighting module. The switch control module is signal-connected to the microcontroller and adjusts the power ratio of each power supply branch according to the instructions of the microcontroller to achieve smooth switching of power supply modes and balanced power distribution, preventing overload of each load.

[0017] The multi-channel power distribution control unit comprises a power detection module, a microcontroller, and a switch control module. The power detection module collects real-time data on the drone's flight load power, the lighting module's load power, and the charging / discharging power of the energy storage module, transmitting this data to the microcontroller in real time. The microcontroller, pre-stored with a power distribution algorithm, analyzes and processes the received data, combining it with the power status of the energy storage module, flight system module, and lighting module to generate mode switching and power distribution commands. The switch control module, connected to the microcontroller, adjusts the power ratio of each power supply branch according to the commands issued by the microcontroller, achieving smooth switching of power supply modes and balanced power distribution, while preventing overload of any load. Its advantages lie in the fact that, through a clearly defined modular design, it achieves closed-loop control of data acquisition, analysis, processing, and command execution, ensuring accurate and reasonable power distribution, effectively avoiding load overload, guaranteeing stable operation of each module, and improving the stability and reliability of the entire system's power supply, providing strong support for efficiently completing tasks such as emergency lighting.

[0018] The external mains power is a single-phase 220V AC power supply provided by the public power grid, which serves as the main input energy for the diversion power supply system. When the external mains power is interrupted, if the remaining power of the energy storage module is greater than the first preset power threshold, the energy storage module automatically switches to power supply mode to provide backup power for the UAV flight system module and lighting module.

[0019] The external mains power is a single-phase 220V AC power supply from the public power grid, serving as the main input energy for the distributed power supply system and providing stable power to all modules of the system. When the external mains power is interrupted, if the remaining power of the energy storage module is greater than a first preset power threshold, the energy storage module will automatically switch to backup power supply mode to provide continuous power to the UAV flight system module and lighting module, ensuring the normal operation of the system's core functions. Its advantages lie in clearly defining the main power source as a stable single-phase 220V power supply from the public power grid, ensuring the stability and continuity of the power supply. Simultaneously, the backup power supply design of the energy storage module effectively responds to sudden power outages, preventing system shutdown due to power outages, ensuring the normal operation of core functions such as flight and lighting in emergency scenarios, improving the system's anti-interference capability and operational reliability, and ensuring stable operation of the entire system under various power supply environments.

[0020] A collaborative control method for a multi-functional emergency lighting unmanned aerial vehicle (UAV) system, comprising the following steps: S1. System Initialization and Parameter Setting: The UAV is powered on, and the power supply system of the ground power base establishes an electrical connection with the external mains power. The UAV's energy storage module, wireless energy receiving module, flight system module, and lighting module enter standby mode, completing system hardware self-test and initialization. The microcontroller of the multi-channel power distribution control unit preloads and sets the first preset power threshold, the second preset power threshold, the first preset power range, and the safe flight threshold. After the preset is completed, the power distribution algorithm enters standby mode. S2. Establishment of Wireless Power Supply Link: The UAV adjusts its flight attitude to align the wireless power receiving module with the wireless power transmitting module of the ground power base station, establishing a contactless wireless power transmission link. After the power supply system undergoes boost, rectification, filtering, and buck regulation, the wireless power transmitting module transmits power to the wireless power receiving module. The wireless power receiving module prioritizes powering the flight system module and lighting module, and uses the remaining power to charge the energy storage module. If there is no power input, the system switches to independent power supply for the energy storage module. S3. Dynamic control of power supply mode: The power distribution algorithm collects the power and load data of each module in real time, and combines the emergency lighting signal of the ground control terminal to dynamically switch to charging priority mode, lighting priority mode, balanced power supply mode or normal power supply mode. S4. Emergency Backup Power Supply for Mains Power Interruption: After detecting an external mains power interruption, the power supply system stops supplying power to the wireless power transmitter module and sends a power outage signal to the UAV. The UAV detects the remaining power of the energy storage module. If it is greater than the first preset power threshold, the energy storage module automatically switches to backup power supply mode to supply power to the flight system module and lighting module. If the remaining power of the energy storage module is less than the first preset power threshold, an alarm signal is issued, the power of the lighting module is reduced, the power supply to the flight system module is prioritized, and the UAV is controlled to land.

[0021] The first preset power threshold in S1 is 30% of the rated power of the energy storage module, flight system module, and lighting module; the second preset power threshold is 80% of the rated power of the energy storage module, flight system module, and lighting module; the first preset power range is 500W-1000W; and the safe flight threshold is 20% of the rated power of the flight system module.

[0022] The first step is system initialization and parameter setting. The UAV body is started, and the power supply system of the ground power base station establishes an electrical connection with the 220V mains power. The power storage module, wireless power receiving module, flight system module, and lighting module of the UAV body enter standby mode and complete the system hardware self-test and initialization. The microcontroller of the multi-channel power distribution control unit preloads and sets various parameters. The first preset power threshold is 30% of the rated power of the power storage module, flight system module, and lighting module. The second preset power threshold is 80% of the rated power of the above modules. The first preset power range is 500W-1000W. The safe flight threshold is 20% of the rated power of the flight system module. After the parameters are set, the power distribution algorithm enters standby mode. The second step involves establishing a wireless power supply link. The UAV adjusts its flight attitude to precisely align the wireless power receiving module with the wireless power transmitting module of the ground power base station, establishing a contactless wireless power transmission link. The step-up transformer module of the power distribution system adjusts the mains voltage, and the AC voltage is converted to DC voltage and high-frequency noise is filtered out by the rectification and filtering module. Then, the voltage is reduced to the working voltage of each module by the step-down and stabilization module. The wireless power transmitting module then transmits the power to the UAV's wireless power receiving module. The wireless power receiving module prioritizes powering the flight system module and the lighting module, and the remaining power is used to charge the energy storage module. If the wireless power receiving module does not receive power input, it switches to independent power supply for the energy storage module. The third step involves dynamic control of the power supply mode. A power allocation algorithm collects real-time data on the power and load of each module, as well as signals from the ground control terminal, and dynamically switches power supply modes: When the remaining power of the energy storage module is below 30%, the remaining power of the flight system module is not below 20%, no emergency lighting trigger signal is received, and the lighting module is not operating, a charging priority mode is triggered. The power allocation algorithm adjusts the output power of the wireless transmitter module to the 500W-1000W range, prioritizing the replenishment of power to the energy storage module until its power reaches 80%, at which point it automatically switches to normal power supply mode. When an emergency lighting trigger signal is received from the ground control terminal, the lighting module's power is below 30%, and the flight system module's power is not below 20%, a lighting priority mode is triggered, prioritizing the replenishment of power to the lighting module until its power reaches 80% or the emergency signal is canceled, at which point it switches to normal power supply mode. When the load of each module is below its rated load and the power of each module is above 30%, a charging priority mode is triggered. In the absence of an emergency signal, the balanced power supply mode is triggered, and power is distributed according to the rated power ratio of each module. When none of the above three modes are triggered, the normal power supply mode is activated, prioritizing the replenishment of power to the flight system module to 80%, then the lighting module to 80%, and finally the energy storage module to 80%.The fourth step is emergency handling of mains power outages. If the diversion power supply system detects an external mains power outage, it immediately stops supplying power to the wireless transmission module and sends a power outage signal to the drone. After detecting the power outage signal, the drone checks the remaining power of the energy storage module. If the energy storage module has more than 30% power, it automatically switches to backup power mode to continuously supply power to the flight system module and lighting module. If the energy storage module has less than 30% power, it issues an alarm signal, reduces the power of the lighting module, prioritizes power supply to the flight system module, and controls the drone to land smoothly to avoid equipment damage.

[0023] During the system initialization phase, clear standards for each core parameter are defined. The first preset power threshold is set at 30% of the rated power of the energy storage module, flight system module, and lighting module; the second preset power threshold is set at 80% of the rated power of these three modules; the first preset power range is set at 500W-1000W; and the safe flight threshold is set at 20% of the rated power of the flight system module. All parameters are pre-loaded into the microcontroller of the multi-channel power distribution control unit, serving as the basis for subsequent power mode switching and power adjustment. The beneficial effect is that by clearly defining the power thresholds and power range standards for each module, a clear and quantifiable basis for power distribution and mode switching of the entire system is provided, avoiding unreasonable power supply problems caused by ambiguous parameters. This ensures the safe operation of the flight system module (meeting the safe flight threshold requirements) and achieves precise power distribution through clear power standards, guaranteeing the coordinated operation of modules such as energy storage, lighting, and flight. It also provides stable parameter support for subsequent mode switching and emergency power supply, improving the standardization, reliability, and operability of system operation, and further enhancing the practical value and emergency adaptability of the entire system.

[0024] The ground-based power supply base station includes a rack, a shielding component mounted on the rack, a sensing component, and a control center. The control center is electrically connected to the sensing component, the power distribution system, and the wireless power transmission module.

[0025] The shielding assembly includes two sets of shielding plates that are rotatably mounted on the frame, a drive component for driving the shielding plates to rotate, the frame includes a bracket and a support plate mounted on the bracket, the power supply system and the wireless power transmission module are both mounted on the support plate, and the sensing component is located on the support plate for real-time sensing of the UAV's position.

[0026] The control center, as the core control unit, is electrically connected to the sensing components, the power supply system, the wireless power transmission module, and the driving components of the shielding components. It receives the docking signal transmitted by the sensing components. Upon receiving the docking signal, the control center immediately sends a command to the driving components of the shielding components. The driving components start and rotate the two sets of shielding plates to the top of the frame, completely covering the drone body docked on the support plate. This provides dustproof, rainproof, and external interference protection for the drone. At the same time, it coordinates the operation of the power supply system and the wireless power transmission module to ensure stable power transmission to the drone body.

[0027] The flight frame includes a main frame, four arms arranged around the main frame, and a support base fixed to the bottom of the main frame. The energy storage module, flight system module, and wireless energy receiving module are all located on the support base. The arms include an extension arm integrally formed with the main frame and a rotating wing arranged at the end of the extension arm away from the main frame. The lighting module is arranged below the extension arm and along the length of the extension arm.

[0028] The lighting modules are fixedly installed below the extension arm and evenly arranged along the length of the extension arm. This arrangement does not affect the normal rotation of the rotor blades and maximizes the lighting coverage, ensuring uniform light distribution during emergency lighting and meeting the needs of scenarios such as nighttime emergency rescue and on-site lighting. Each module is linked with the power storage module and flight system module through wiring to achieve a stable power supply and coordinated operation of each component.

[0029] The beneficial effects of this invention are as follows: The overall system achieves safe and stable power transmission through non-contact wireless power supply, avoiding the potential for poor contact and safety hazards associated with contact power supply. Simultaneously, the multi-mode power supply algorithm design can accurately allocate power according to emergency lighting needs, module power status, and load conditions. This ensures the safety baseline of the flight system while prioritizing core mission requirements such as emergency lighting, and also achieves balanced and efficient power utilization when there are no special needs, completely eliminating energy waste. The intelligent shielding structure of the ground base station and the modular installation design of the drone not only enhance the dust and rain protection capabilities of the equipment when parked outdoors but also ensure that each module is securely installed and operates stably. Furthermore, the backup power supply and emergency landing mechanism in case of mains power interruption further improve the system's anti-interference capability and fault tolerance in complex environments. The entire system achieves closed-loop management of power supply, control, protection, and emergency response, significantly improving the practicality, reliability, and safety of the multi-functional emergency lighting drone system in actual emergency rescue scenarios, possessing extremely high engineering application value and promising prospects for promotion.

It dynamically switches between charging priority mode, lighting priority mode, balanced power supply mode, and normal power supply mode to adjust the output power and energy distribution ratio of the wireless energy transmission module 4.

[0034] Ground power base station 1 has a built-in power distribution system 3 and a wireless power transmission module 4. After the power distribution system 3 is connected to external mains power, it transmits power to the wireless power transmission module 4. The wireless power receiving module 9 of the UAV body 2 establishes a contactless power connection with the wireless power transmission module 4 through a wireless power transmission link, receiving power transmitted from the ground to replenish the power of the flight system module 7, lighting module 8, and energy storage module 6.

The beneficial effects are that, through the non-contact wireless power supply design between the ground power base station 1 and the UAV body 2, stable power transmission and multi-module power supply are achieved. Combined with the multi-mode dynamic switching function of the power distribution algorithm, power can be rationally allocated according to the real-time operating status of each module, improving the targeting and efficiency of power supply, ensuring the stable operation of the flight system module 7 and the lighting module 8. At the same time, the coordinated power supply design of the energy storage module 6 and the wireless power receiving module 9 further improves the reliability of the system's power supply and enhances the system's practicality and adaptability.

[0035] The charging priority mode prioritizes the wireless energy receiving module 9 to replenish the energy storage module 6. The charging priority mode is triggered when the remaining power of the energy storage module 6 is lower than a first preset power threshold, the remaining power of the flight system module 7 is not lower than a safe flight threshold, no emergency lighting trigger signal is received from the ground control terminal, and the lighting module 8 is not in operation. The power allocation algorithm adjusts the output power of the wireless energy transmitting module 4 to a first preset power range according to the trigger conditions, and prioritizes the delivery of energy within the first preset power range to the energy storage module 6 until the remaining power of the energy storage module 6 reaches a second preset threshold. When the remaining power of the energy storage module 6 reaches the second preset threshold, it automatically exits the charging priority mode and switches to the normal power supply mode.

[0036] When the remaining power of the energy storage module 6 is lower than the first preset power threshold, and the remaining power of the flight system module 7 is not lower than the safe flight threshold, no emergency lighting trigger signal is received from the ground control terminal, and the lighting module 8 is not in working condition, the charging priority mode is triggered. At this time, the wireless energy receiving module 9 prioritizes replenishing the energy storage module 6. The power allocation algorithm adjusts the output power of the wireless energy transmitting module 4 to the first preset power range according to the trigger condition, and prioritizes the delivery of energy within this range to the energy storage module 6, continuously replenishing the energy storage module 6 until its remaining power reaches the second preset threshold. When the battery level reaches the second preset threshold, the charging priority mode automatically exits and switches to normal power supply mode. The beneficial effect is that by precisely activating the charging priority mode through clear triggering conditions, the charging priority mode is prioritized to ensure the replenishment of the battery storage module 6, while also taking into account the safe flight requirements of the flight system module 7. This avoids the waste of power when emergency lighting needs are not triggered or the lighting module 8 is not working. Through power adjustment and automatic mode switching, the power is rationally allocated, improving the charging efficiency of the battery storage module 6 and ensuring that the battery storage module 6 has sufficient power reserves. This provides a guarantee for backup power supply in subsequent emergency scenarios and further improves the rationality and reliability of the entire system's power supply.

[0037] The lighting priority mode prioritizes the wireless power receiving module 9 to replenish the lighting module 8. The triggering condition for the lighting priority mode is that when the UAV body 2 receives an emergency lighting trigger signal sent by the ground control terminal, and the power of the lighting module 8 is lower than a first preset power threshold, and the remaining power of the flight system module 7 is not lower than a safe flight threshold, the power allocation algorithm adjusts the output power of the wireless power transmitting module 4 to a first preset power range according to the triggering condition, and prioritizes the delivery of power within the first preset power range to the lighting module 8 until the remaining power of the lighting module 8 reaches a second preset threshold. When the remaining power of the lighting module 8 reaches the second preset threshold or the emergency lighting trigger signal is canceled, the lighting priority mode is automatically exited and the normal power supply mode is switched.

[0038] When the UAV body 2 receives an emergency lighting trigger signal from the ground control terminal, and the power of the lighting module 8 is lower than the first preset power threshold and the remaining power of the flight system module 7 is not lower than the safe flight threshold, the lighting priority mode is triggered. At this time, the wireless power receiving module 9 prioritizes replenishing the power of the lighting module 8. According to the trigger condition, the power allocation algorithm adjusts the output power of the wireless power transmitting module 4 to the first preset power range, and prioritizes the delivery of power within this range to the lighting module 8, continuously replenishing the power of the lighting module 8 until its remaining power reaches the second preset threshold. When the remaining power of the lighting module 8 reaches the second preset threshold or the emergency lighting mode is activated, the lighting priority mode is triggered. When the trigger signal is canceled, the system automatically exits the lighting priority mode and switches to the normal power supply mode. The beneficial effect is that it ensures the timely activation of the lighting priority mode in emergency lighting scenarios through precise trigger conditions, prioritizes the power replenishment of the lighting module 8, meets the core needs of emergency lighting, and at the same time takes into account the safe flight threshold requirements of the flight system module 7, avoiding flight safety hazards caused by priority power supply. Through power adjustment and automatic mode switching, it achieves precise power distribution in emergency scenarios, improves the power supply efficiency and continuity of the lighting module 8, ensures the smooth operation of emergency lighting tasks, and further enhances the emergency response capability and practical reliability of the entire system.

[0039] The balanced power supply mode involves the wireless energy receiving module 9 replenishing power to the flight system module 7, lighting module 8, and energy storage module 6 according to the rated power ratio of each module. The balanced power supply mode is triggered when the load power of the lighting module 8 is lower than its rated power and the remaining power of the lighting module 8 is higher than a first preset power threshold, the load power of the flight system module 7 is lower than its rated power and the remaining power of the flight system module 7 is higher than the first preset power threshold, the remaining power of the energy storage module 6 is higher than the first preset power threshold, and no charging priority or lighting priority mode trigger signal is received. The power allocation algorithm, based on the trigger conditions, transmits power to the flight system module 7, lighting module 8, and energy storage module 6 according to the rated power ratio of each module via the wireless energy transmitting module 4. If a charging priority mode or lighting priority mode trigger signal is received during operation, the system switches to the charging priority mode or lighting priority mode. When any module experiences a load power reaching its rated power and a remaining power exceeding a second preset power threshold, the system automatically exits the balanced power supply mode and switches to the normal power supply mode.

[0040] When the load power of lighting module 8 is lower than its rated power and the remaining power is higher than the first preset power threshold, the load power of flight system module 7 is lower than its rated power and the remaining power is higher than the first preset power threshold, and the remaining power of energy storage module 6 is higher than the first preset power threshold, and no trigger signal for charging priority mode or lighting priority mode is received, the balanced power supply mode is triggered. At this time, the wireless power receiving module 9 replenishes the power of the three modules according to the rated power ratio of flight system module 7, lighting module 8, and energy storage module 6. The power distribution algorithm, based on the above trigger conditions, transmits power to flight system module 7, lighting module 8, and energy storage module 6 respectively through wireless power transmitting module 4 according to the rated power ratio of each module. During operation, if a charging priority mode or lighting priority mode is received, the balanced power supply mode is triggered. The trigger signal of the lighting priority mode immediately switches to the corresponding power supply mode. When any module's load power reaches its rated power or its remaining power exceeds the second preset power threshold, it automatically exits the balanced power supply mode and switches to the normal power supply mode. Its advantages are that precise triggering conditions ensure that the balanced power supply mode is activated only when there is no urgent power supply demand from any module. Distributing power according to the rated power ratio can achieve the balance of power supply to each module, avoiding the energy waste caused by excessive power supply to a single module. At the same time, it can prevent insufficient power supply to some modules from affecting the stability of operation. The flexible mode switching mechanism can respond to emergency power supply demands and changes in module operating status in a timely manner, ensuring the coordinated and stable operation of each module, and further improving the rationality, efficiency and reliability of the entire system's power supply.

[0041] The normal power supply mode prioritizes replenishing the flight system module 7 with power to the second preset power threshold, then replenishes the lighting module 8 with power to the second preset power threshold, and finally replenishes the energy storage module 6 with power to the second preset power threshold. The normal power supply mode is triggered when the charging priority mode, lighting priority mode, and balanced power supply mode are not triggered.

[0042] When the charging priority mode, lighting priority mode, and balanced power supply mode are not triggered, the normal power supply mode is activated. Power is supplied to each module sequentially according to the priority order of "flight system module 7 → lighting module 8 → energy storage module 6" until each module reaches the second preset power threshold. The beneficial effect is that, through clear priority sequencing and power replenishment standards, the stable operation of flight system module 7 is ensured, the normal operation of lighting module 8 is guaranteed, and power resources are rationally allocated to avoid energy waste. This balances the power supply needs of each module with the stability and orderliness of system operation, further improving the rationality and practicality of the entire system's power supply and adapting to the normalized power supply needs in emergency scenarios.

The input terminal of the step-up transformer module is connected to the external mains power supply to adjust the voltage level of the external mains power supply to meet the input requirements of the subsequent rectifier and filter module and step-down voltage regulator module. The input terminal of the rectifier and filter module is connected to the output terminal of the step-up transformer module to convert the stepped-up AC voltage into DC voltage and filter out high-frequency noise in the voltage. The input terminal of the step-down voltage regulator module is connected to the output terminal of the rectifier and filter module to step down the DC voltage to a level suitable for the working voltage of the UAV flight system module 7, lighting module 8, and energy storage module 6, while also implementing current limiting protection. The multi-channel power distribution control unit has the built-in power distribution algorithm to receive various load power data and status signals to realize the power distribution and dynamic switching of the power supply mode.

The rectifier and filter module converts the boosted AC voltage to DC voltage and filters out high-frequency noise. The step-down voltage regulator module reduces the DC voltage to a level suitable for the operating voltage of each module on the UAV, while also implementing current-limiting protection. The multi-channel power distribution control unit has a built-in power distribution algorithm that receives various load power data and status signals to complete the power distribution and dynamic switching of power supply modes, ensuring a stable power supply. Its advantages lie in the fact that through the coordinated operation of each module, it achieves reasonable conversion and stable output of AC power, ensuring that the power supply meets the operating requirements of each module on the UAV, avoiding problems such as voltage instability and noise interference, improving power utilization efficiency, and ensuring the stability and reliability of the power supply. Furthermore, through current-limiting protection and dynamic power supply switching, it further enhances the safety and practicality of the system operation, providing strong support for the stable operation of the entire system.

[0045] The multi-channel power distribution control unit includes a power detection module, a microcontroller, and a switch control module. The power detection module is used to collect real-time data on the flight load power of the UAV body 2, the load power of the lighting module 8, and the charging and discharging power of the energy storage module 6, and transmit the collected data to the microcontroller in real time. The microcontroller has a pre-stored power distribution algorithm, analyzes and processes the received data, and generates mode switching instructions and power distribution instructions based on the power status of the energy storage module 6, the flight system module 7, and the lighting module 8. The switch control module is signal-connected to the microcontroller and adjusts the power ratio of each power supply branch according to the instructions of the microcontroller to achieve smooth switching of power supply modes and balanced distribution of power, preventing overload of each load.

[0046] The multi-channel power distribution control unit comprises a power detection module, a microcontroller, and a switch control module. The power detection module collects real-time data on the drone's flight load power, the lighting module 8's load power, and the charging / discharging power of the energy storage module 6, transmitting this data to the microcontroller in real time. The microcontroller pre-stores a power distribution algorithm, analyzes and processes the received data, and, combined with the power status of the energy storage module 6, flight system module 7, and lighting module 8, generates mode switching and power distribution commands. The switch control module is signal-connected to the microcontroller and, based on the commands issued by the microcontroller, adjusts the power ratio of each power supply branch to achieve smooth switching of power supply modes and balanced power distribution, while preventing overload of any load. Its advantages lie in the fact that, through a clearly defined modular design, it achieves closed-loop control of data acquisition, analysis, processing, and command execution, ensuring accurate and reasonable power distribution, effectively avoiding load overload, guaranteeing stable operation of each module, and improving the stability and reliability of the entire system's power supply, providing strong support for efficiently completing tasks such as emergency lighting.

[0047] The external mains power is a single-phase 220V AC power supply provided by the public power grid, which serves as the main input energy for the diversion power supply system 3. When the external mains power is interrupted, if the remaining power of the energy storage module 6 is greater than the first preset power threshold, the energy storage module 6 automatically switches to power supply mode to provide backup power for the UAV flight system module 7 and the lighting module 8.

[0048] The external mains power is a single-phase 220V AC power supply from the public power grid, serving as the main input energy for the shunt power supply system 3, providing stable power to all modules of the system. When the external mains power is interrupted, if the remaining power of the energy storage module 6 is greater than the first preset power threshold, the energy storage module 6 will automatically switch to backup power supply mode to provide continuous power to the UAV flight system module 7 and the lighting module 8, ensuring the normal operation of the system's core functions. Its advantages lie in clearly defining the main power source as a stable single-phase 220V power supply from the public power grid, ensuring the stability and continuity of the power supply. Simultaneously, the backup power supply design of the energy storage module 6 effectively addresses the sudden situation of mains power interruption, preventing the system from stopping due to mains power failure. This ensures the normal operation of core functions such as flight and lighting in emergency scenarios, improves the system's anti-interference capability and operational reliability, and ensures the stable operation of the entire system under various power supply environments.

[0049] A collaborative control method for a multi-functional emergency lighting unmanned aerial vehicle (UAV) system, comprising the following steps: S1. System Initialization and Parameter Setting: The UAV body 2 is started, and the power supply system 3 of the ground power base station 1 establishes an electrical connection with the external mains power. The power storage module 6, wireless power receiving module 9, flight system module 7, and lighting module 8 of the UAV body 2 enter standby mode, completing system hardware self-test and initialization. The microcontroller of the multi-channel power distribution control unit preloads and sets the first preset power threshold, the second preset power threshold, the first preset power range, and the safe flight threshold. After the preset is completed, the power distribution algorithm enters standby mode. S2. Establishment of Wireless Power Supply Link: The UAV body 2 adjusts its flight attitude to align the wireless power receiving module 9 with the wireless power transmitting module 4 of the ground power supply base station 1, establishing a non-contact wireless power transmission link; after the power supply system 3 undergoes boost, rectification, filtering, and buck regulation, the power is transmitted from the wireless power transmitting module 4 to the wireless power receiving module 9; the wireless power receiving module 9 prioritizes powering the flight system module 7 and the lighting module 8, and the remaining power is used to charge the energy storage module 6; if there is no power input, the power storage module 6 is switched to independent power supply. S3. Dynamic control of power supply mode: The power distribution algorithm collects the power and load data of each module in real time, and combines the emergency lighting signal of the ground control terminal to dynamically switch to charging priority mode, lighting priority mode, balanced power supply mode or normal power supply mode. S4. Emergency backup power supply during mains power outage: After detecting an external mains power outage, the diversion power supply system 3 stops supplying power to the wireless power transmission module 4 and sends a power outage signal to the drone body 2; the drone body 2 detects the remaining power of the energy storage module 6. If it is greater than the first preset power threshold, the energy storage module 6 automatically switches to backup power supply mode to supply power to the flight system module 7 and the lighting module 8; if the remaining power of the energy storage module 6 is less than the first preset power threshold, an alarm signal is issued, the power of the lighting module 8 is reduced, the power supply to the flight system module 7 is prioritized, and the drone is controlled to land.

[0050] The first preset power threshold in S1 is 30% of the rated power of the energy storage module 6, flight system module 7, and lighting module 8; the second preset power threshold is 80% of the rated power of the energy storage module 6, flight system module 7, and lighting module 8; the first preset power range is 500W-1000W; and the safe flight threshold is 20% of the rated power of the flight system module 7.

[0051] The first step is system initialization and parameter setting. The UAV body 2 is started, and the power supply system 3 of the ground power base station 1 establishes an electrical connection with the 220V mains power. The power storage module 6, wireless power receiving module 9, flight system module 7, and lighting module 8 of the UAV body 2 enter standby mode, completing the system hardware self-test and initialization. The microcontroller of the multi-channel power distribution control unit preloads and sets various parameters. The first preset power threshold is 30% of the rated power of the power storage module 6, flight system module 7, and lighting module 8. The second preset power threshold is 80% of the rated power of the above modules. The first preset power range is 500W-1000W. The safe flight threshold is 20% of the rated power of the flight system module 7. After the parameters are set, the power distribution algorithm enters standby mode. The second step is to establish a wireless power supply link. The UAV body 2 adjusts its flight attitude to precisely align the wireless power receiving module 9 with the wireless power transmitting module 4 of the ground power supply base station 1, establishing a non-contact wireless power transmission link. The step-up transformer module of the power supply system 3 adjusts the mains voltage, and the AC voltage is converted to DC voltage and high-frequency noise is filtered out by the rectification and filtering module. Then, the voltage is reduced to the working voltage of each module by the step-down and stabilization module. The wireless power transmitting module 4 transmits the power to the UAV's wireless power receiving module 9. The wireless power receiving module 9 prioritizes powering the flight system module 7 and the lighting module 8. The remaining power is used to charge the energy storage module 6. If the wireless power receiving module 9 does not receive power input, the energy storage module 6 will be powered independently. The third step involves dynamic control of the power supply mode. A power allocation algorithm collects real-time data on the power and load of each module, as well as signals from the ground control terminal, and dynamically switches power supply modes: When the remaining power of the energy storage module 6 is below 30%, the remaining power of the flight system module 7 is not below 20%, no emergency lighting trigger signal is received, and the lighting module 8 is not operating, a charging priority mode is triggered. The power allocation algorithm adjusts the output power of the wireless transmitter module to the 500W-1000W range, prioritizing the replenishment of power to the energy storage module 6 until its power reaches 80%, at which point it automatically switches to the normal power supply mode. When an emergency lighting trigger signal is received from the ground control terminal, the power of the lighting module 8 is below 30%, and the power of the flight system module 7 is not below 20%, a lighting priority mode is triggered, prioritizing the replenishment of power to the lighting module 8 until its power reaches 80% or the emergency signal is canceled, at which point it switches to the normal power supply mode. When the load of each module is below its rated load and the power of each module is above 30%, a charging priority mode is triggered. In the absence of an emergency signal, the balanced power supply mode is triggered, and power is distributed according to the rated power ratio of each module. When none of the above three modes are triggered, the normal power supply mode is activated, prioritizing the replenishment of power to the flight system module 7 to 80%, then the lighting module 8 to 80%, and finally the energy storage module 6 to 80%.The fourth step is emergency handling of mains power outages. If the power supply system 3 detects an external mains power outage, it immediately stops supplying power to the wireless transmitter module and sends a power outage signal to the drone body 2. After detecting the power outage signal, the drone body 2 checks the remaining power of the energy storage module 6. If the energy storage module 6 has a power level greater than 30%, it automatically switches to backup power supply mode to continuously supply power to the flight system module 7 and the lighting module 8. If the energy storage module 6 has a power level less than 30%, it issues an alarm signal, reduces the power of the lighting module 8, prioritizes the power supply to the flight system module 7, and controls the drone to land smoothly to avoid equipment damage.

[0052] During the system initialization phase, the standards for each core parameter were clearly defined. The first preset power threshold was set at 30% of the rated power of the energy storage module 6, flight system module 7, and lighting module 8; the second preset power threshold was set at 80% of the rated power of the above three modules; the first preset power range was set at 500W-1000W; and the safe flight threshold was set at 20% of the rated power of flight system module 7. All parameters were pre-loaded into the microcontroller of the multi-channel power distribution control unit, serving as the basis for subsequent power mode switching and power adjustment. The beneficial effect is that by clearly defining the power thresholds and power range standards for each module, a clear and quantifiable basis for power distribution and mode switching of the entire system is provided, avoiding unreasonable power supply problems caused by ambiguous parameters. This ensures the safe operation of flight system module 7 (meeting the safe flight threshold requirements) and achieves precise power distribution through clear power standards, guaranteeing the coordinated operation of modules such as energy storage, lighting, and flight. It also provides stable parameter support for subsequent mode switching and emergency power supply, improving the standardization, reliability, and operability of system operation, and further enhancing the practical value and emergency adaptability of the entire system.

[0053] The ground power base station 1 includes a frame 11, a shielding component, a sensing component 24 and a control center 13 mounted on the frame 11. The control center 13 is electrically connected to the sensing component 24, the power distribution system 3 and the wireless power transmission module 4.

[0054] The shielding assembly includes two sets of shielding plates 14 rotatably mounted on the frame 11 and a drive component 15 for driving the shielding plates 14 to rotate. The frame 11 includes a bracket 16 and a support plate 17 mounted on the bracket 16. The power supply system 3 and the wireless power transmission module 4 are both mounted on the support plate 17. The sensing component 24 is located on the support plate 17 for real-time sensing of the position of the UAV body 2.

[0055] The control center 13, as the core control unit, is electrically connected to the sensing component 24, the power supply system 3, the wireless energy transmission module 4, and the drive component 15 of the shielding component. It receives the docking signal transmitted by the sensing component 24. When the control center 13 receives the docking signal from the sensing component 24, it immediately sends a command to the drive component 15 of the shielding component. The drive component 15 starts and drives the two sets of shielding plates 14 to rotate above the frame 11, completely covering the drone body 2 docked on the support plate 17. This achieves dustproof, rainproof, and external interference protection for the drone. At the same time, it coordinates the operation of the power supply system 3 and the wireless energy transmission module 4 to ensure stable power transmission to the drone body 2.

[0056] The flight frame includes a main frame 18, four arms 19 arranged around the main frame 18, and a support base 21 fixed to the bottom of the main frame 18. The power storage module 6, flight system module 7, and wireless power receiving module 9 are all located on the support base 21. The arms 19 include an extension arm 22 integrally formed with the main frame 18 and a rotating wing 23 arranged at the end of the extension arm 22 away from the main frame 18. The lighting module 8 is arranged below the extension arm 22 and along the length of the extension arm 22.

[0057] The lighting module 8 is fixedly installed below the extension arm 22 and evenly arranged along the length of the extension arm 22. This arrangement does not affect the normal rotation of the rotary wing 23 and maximizes the lighting coverage, ensuring uniform light distribution during emergency lighting and meeting the needs of nighttime emergency rescue, on-site lighting, and other scenarios. Each module is linked with the power storage module 6 and the flight system module 7 through wiring to achieve a stable power supply and coordinated operation of each component.
