[0036] In this implementation scheme, the platform equipment includes one display and control console at the unmanned ship base station and three display and control consoles at the mission payload base station.

[0037] Specifically, the unmanned ship power supply and distribution module includes: a pud unit, a power management unit, and a battery management unit; the pud unit is used to distribute power supply to the unmanned ship electrical equipment and components, and to supply power to the internal equipment of the platform; the power management unit is used to manage and monitor the power supply of the power supply system, including monitoring and adjusting the voltage, current, and power; the battery management unit is used to manage the battery of the unmanned ship equipment, including monitoring the battery status of the unmanned ship platform equipment and controlling the charging and discharging of the battery of the unmanned ship equipment.

[0038] In this implementation scheme, the PUD unit is a power distribution unit, which can distribute power supply to various electrical equipment and components of the unmanned ship and power the internal equipment of the platform. The PUD unit usually includes multiple output ports, each of which can be connected to an electrical device or component; the power management unit is used to manage and monitor the power supply of the power supply system, including monitoring and adjusting parameters such as voltage, current, and power. It can ensure the stability and reliability of the power supply, and at the same time control the charging and discharging of the battery to extend the battery life; the battery management unit is mainly used to manage the battery of the unmanned ship equipment, including monitoring the battery status of the unmanned ship platform equipment, controlling the charging and discharging of the unmanned ship equipment battery, etc. By monitoring and controlling the battery status, the battery management unit can ensure the service life and safety of the battery.

[0039] Specifically, the specific process of collecting the working status data of the platform equipment is as follows: obtain the working status data of the platform equipment, including the power factor, battery energy density, battery discharge rate, input power, output power, power consumption, power system rated power, maximum power requirement, switch status, voltage, and current of the platform equipment, and store them in a data storage unit.

[0040] See also Figure 2 Specifically, based on the working status data of the platform equipment, the working performance of the platform equipment is analyzed, and the specific process of calculating the working performance index of the platform equipment is as follows: by calculating the energy efficiency ratio index, the power load index of the platform equipment, and the battery energy efficiency index of the platform equipment for each platform equipment, the platform equipment is , according to the influence of the platform equipment energy efficiency ratio index, the platform equipment power load index, and the platform equipment battery energy efficiency index on the platform equipment working performance index, calculate the working performance index of each platform equipment; the specific calculation formula of each platform equipment working performance index is as follows:

[0041] ;

[0042] In the formula, represents the working performance index of the j-th equipment, represents the energy efficiency ratio index of the j-th equipment, represents the power load index of the jth device, represents the battery energy efficiency index of the jth device, Indicates the weight factor of the energy efficiency ratio index of the platform equipment corresponding to the working performance index of the platform equipment, Indicates the weight factor of the power load index of the platform equipment corresponding to the working performance index of the platform equipment, It represents the weight factor of the battery energy efficiency index of the platform equipment corresponding to the working performance index of the platform equipment, e represents the natural constant, .

[0043] In this implementation scheme, the working performance index of the platform equipment is calculated to evaluate the performance level of the platform equipment during operation, so as to help the operators of the unmanned ship system better understand the working status and performance of each platform equipment, timely discover possible problems and hidden dangers, and make corresponding adjustments and optimizations to the equipment according to the index results, so as to improve the energy efficiency and reliability of the entire unmanned ship system. At the same time, this calculation method also provides a scientific and quantitative analysis method for the operation management and maintenance of the unmanned ship system, which helps to reduce the system operating costs and reduce the occurrence of equipment failures; through the analysis and modeling of historical data or a large amount of sample data, mathematical statistical methods are used to calculate the influence of the energy efficiency index of the platform equipment, the power load index of the platform equipment, and the battery energy efficiency index of the platform equipment on the working performance index of the platform equipment and the relative weight.

[0044] Specifically, the calculation process of the energy efficiency ratio index of each device is as follows: by obtaining the input power and output power of each device per hour, the device is , numbered every hour , according to the influence of each unit's input power and output power, calculate the energy efficiency index of each unit; the calculation formula of the energy efficiency index of the unit is as follows:

[0045] ;

[0046] In the formula, represents the energy efficiency ratio index of the j-th equipment, represents the output power of the jth device at the i-th hour, It represents the input power of the jth equipment at the i-th hour, It represents the correction compensation factor of the energy efficiency ratio index of the whole equipment.

[0047] In this implementation scheme, by obtaining the input power and output power of each platform equipment per hour, the working status and performance of each platform equipment can be understood in real time. By calculating the energy efficiency index of each platform, the working performance of different platform equipment can be comprehensively evaluated and compared, so as to make targeted equipment adjustments and optimizations to improve the overall energy efficiency and reliability of the unmanned ship system; at the same time, according to the correction compensation factor in the calculation formula, the calculation results can be further corrected and optimized to ensure that the calculation results are more accurate and reliable; for the control of power supply and distribution of unmanned ship platform equipment, the power load and power capacity of each platform equipment are monitored, adjusted and optimized in real time to prevent power overload or insufficient, thereby ensuring the safety and stable operation of the unmanned ship system; by establishing a platform equipment working model, using mathematical models and computer simulation technology, the influence of the input power and output power of the platform equipment on the energy efficiency of the platform equipment is studied, and the correction compensation factor is determined.

[0048] Specifically, the calculation process of the power load index of each platform device is as follows: by obtaining the platform device voltage and platform device current of each platform device within one hour, the platform device is , numbered every hour , calculate the power supply load index of each platform device according to the influence degree of each platform device voltage and platform device current;

[0049] ;

[0050] In the formula, represents the power load index of the jth equipment, It represents the average power factor of the jth equipment in the i-th hour, represents the power consumption of the jth device in the i-th hour, Indicates the weight factor of the average power factor of the platform equipment corresponding to the power load index of the platform equipment, Indicates the weight factor of the power consumption of the platform device corresponding to the power load index of the platform device.

[0051] In this embodiment, by monitoring the power load index of the platform equipment, it can be determined whether the load of each platform equipment is balanced. If the power load index of a platform equipment is found to be high, it may mean that the equipment is overloaded, which may cause power overload or unstable operation. By timely adjusting the power supply and distribution system, load balancing can be achieved and the reliability and stability of the power supply system can be improved.

[0052] Specifically, the calculation process of the battery energy efficiency index of each device is as follows:

[0053] ;

[0055] In this implementation, the battery energy efficiency index can be used to understand the power capacity usage of each device, and then load management can be performed. If the battery energy efficiency index of a device exceeds the set threshold, it may mean that the device is overloaded and the capacity is insufficient to support its normal operation. In this case, measures can be taken to manage the load, such as adjusting the device's working mode, optimizing the power supply strategy, or increasing the power supply capacity to ensure the reliable operation of the device and the stability of the power supply system.

[0056] Specifically, based on the working performance index of each platform equipment, the specific process of controlling the power supply and distribution of the unmanned ship platform equipment is as follows: based on the platform equipment working performance index, compare it with the minimum allowable value of the platform equipment working performance index. If the platform equipment working performance index is less than the minimum allowable value of the platform equipment working performance index, power is supplied to the platform equipment; based on the platform equipment working performance index, compare it with the threshold of the platform equipment working performance index. If the platform equipment working performance index is greater than the threshold of the platform equipment working performance index, control the power supply and distribution of the unmanned ship platform equipment through the unmanned ship power supply and distribution module, and perform power-off protection.

[0057] In this implementation scheme, power is supplied according to the minimum allowable value of the working performance index of each platform device, which can ensure that the device operates within the normal working range; by comparing with the threshold value of the working performance index of each platform device, it can be determined whether the device exceeds the normal working range. If the working performance index exceeds the threshold value, it may indicate that the device is in a high-load working state, which may cause a failure or an accident. By controlling the platform device fault diagnosis unit, timely measures can be taken to maintain and repair the equipment to avoid losses caused by equipment failure.

[0058] Specifically, the unmanned ship power supply and distribution module controls the power supply and distribution of the unmanned ship platform equipment, and the specific process of power-off protection is as follows: the power management unit based on the unmanned ship power supply and distribution module controls the fuse to disconnect the platform equipment from the unmanned ship's primary power supply, and protects the circuit through overcurrent through the power supply fuse plus the current limiting resistor, and continuously monitors the working status of the platform equipment.

[0059] In this implementation, when a fault or abnormality occurs in the platform equipment, by disconnecting the connection with the primary power supply of the unmanned ship, the fault can be prevented from spreading to other parts, reducing potential safety risks. At the same time, the overcurrent protection circuit can prevent equipment damage and fire accidents caused by overcurrent; by real-time monitoring of the working status of the platform equipment, once an abnormality such as overcurrent is found, it can be determined whether the equipment is faulty. After power failure, fault diagnosis and maintenance can be carried out, and the faulty equipment can be repaired or replaced in time to ensure the normal operation of the platform equipment.
