[0002] With the frequent occurrence of natural disasters and emergencies, the power supply for vehicles in rescue, military, outdoor operations and other scenarios is particularly important. The vehicle-mounted mobile emergency power supply control method and system is a power management technology designed specifically for vehicles to meet energy needs in emergencies or power outages. Such systems are usually integrated into special vehicles such as ambulances, fire trucks, and military vehicles. When the main power supply fails, it can automatically or manually switch to the backup power supply to ensure the normal operation of the equipment. This system not only improves the efficiency and safety of emergency response, but also provides a strong guarantee for continuous operations in complex environments.

[0003] Existing vehicle-mounted mobile emergency power supply systems mainly rely on traditional battery and generator technology. These systems usually include components such as automatic switching switches, charging controllers, and inverters. When the vehicle's main power supply fails or is interrupted, the system can automatically switch to the backup power supply to maintain the normal operation of key equipment on the vehicle (such as communication devices, lighting equipment, medical equipment, etc.). These systems usually use voltage monitoring and current sensing technology to determine the status of the main power supply and trigger the start of the emergency power supply when necessary. In addition, the existing technology also includes a manual switching function to cope with complex emergency situations.

[0004] For example, the patent application with publication number: CN114326470A discloses a power control system, a power control method and a device thereof, including: a central brain layer, an on-off analysis layer and an on-off execution layer; the control program of the central brain layer is used to obtain sensor data and generate control instructions according to the request of the user or the vehicle; the information matching unit of the on-off analysis layer is used to determine the device that needs to be controlled on and off according to the control instruction; the power control unit of the on-off execution layer is used to control the working state of the device that needs to be controlled on and off according to the control instruction.

[0005] For example, the invention patent with announcement number: CN108241361B announces a vehicle power control method, controller and vehicle, including: before the vehicle controller is powered off, judging whether the controller has a need to power on after powering off; if the controller has a need to power on after powering off, then after the controller is powered off, detecting whether a preset power-on trigger condition is met; if it is detected that the power-on trigger condition is met, controlling the controller to power on. The present invention realizes autonomous power-on of the controller by judging whether the controller has a need to power on after powering off before the controller is powered off. Autonomous power-on of the controller can not only reduce the static power consumption of the vehicle, but also improve the degree of automation of the vehicle.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1 As shown, it is a flow chart of the vehicle-mounted mobile emergency power supply control method provided in an embodiment of the present application, the method comprising the following steps: monitoring the power demand of the vehicle-mounted electrical equipment through the equipment monitoring sensor to obtain the equipment power consumption data, and obtaining the equipment power demand evaluation index according to the equipment power consumption data and the reference equipment data obtained from the preset database, the equipment monitoring sensor is used to monitor the power demand of the vehicle-mounted electrical equipment, the equipment power consumption data is used to evaluate the power demand of the vehicle-mounted electrical equipment, and the equipment power demand evaluation index is used to quantify the power demand degree of the vehicle-mounted electrical equipment; comparing the equipment power demand evaluation index with the equipment power demand evaluation interval obtained from the preset database, taking priority adjustment measures based on the comparison result, the priority adjustment measures indicating modifying the preset power supply priority of the corresponding vehicle-mounted electrical equipment to obtain the emergency power supply priority, and the priority adjustment measures are used to adjust the current vehicle-mounted electrical equipment The preset power supply priority is used to adapt to the current emergency situation. The preset power supply priority is preset according to the current task requirements of the on-board electrical equipment. The emergency power supply priority indicates the priority of the preset power supply priority of the on-board electrical equipment adjusted according to the actual emergency task requirements; the power supply data is obtained by monitoring the power consumption and impact of the emergency power supply through the power supply data acquisition equipment, and the power supply evaluation index is obtained according to the power supply data and the power reference data obtained from the preset database. The power supply evaluation index is compared with the power supply evaluation interval obtained from the preset database to take power supply adjustment measures. The power supply data acquisition equipment is used to collect data related to the power supply capacity. The power supply evaluation index is used to quantify the power supply capacity of the emergency power supply under the current circumstances. The power supply adjustment measures indicate that different power supplies are provided to on-board electrical equipment of different priorities according to the actual power situation of the current emergency power supply.

[0025] In this embodiment, the equipment monitoring sensor includes a voltage sensor and a current sensor. The equipment monitoring sensor monitors the power demand of the vehicle-mounted electrical equipment in real time, and can dynamically adjust the power supply priority of each vehicle-mounted electrical equipment to ensure that key equipment can obtain power first in emergency situations; by comprehensively evaluating the power supply demand of the vehicle-mounted electrical equipment and the power supply capacity of the emergency power supply, the optimal allocation of power resources can be achieved in emergency situations; through real-time data monitoring and algorithms, the intelligence level of vehicle power management is improved, so that the vehicle-mounted electrical equipment can better coordinate work in emergency situations, reduce the risk of failure caused by insufficient power, and thus improve the overall safety and reliability of the vehicle, and achieve the effect of improving the timeliness of power distribution of the emergency power supply in emergencies.

[0026] Among them, the specific process of obtaining the equipment power consumption data is as follows: the voltage signal of the vehicle-mounted electrical equipment is measured in real time by a voltage sensor, and the voltage signal is converted through a voltage conversion formula to obtain the equipment voltage, and the voltage conversion formula is used to convert the voltage signal into a voltage value; the current signal of the vehicle-mounted electrical equipment is measured in real time by a current sensor, and the current signal is converted through a current conversion formula to obtain the equipment current, and the current conversion formula is used to convert the current signal into a current value; the equipment power consumption data includes equipment current and equipment voltage.

[0027] In this embodiment, the voltage signal detected by the voltage sensor in real time is firstly subjected to signal adjustment (such as filtering, amplification, or attenuation), and then analog-to-digital conversion (ADC) is performed to convert the analog voltage signal into a digital signal and output an ADC digital value, and then the ADC digital value is brought into a voltage conversion formula to obtain a voltage value, i.e., a device voltage, wherein the voltage conversion formula is specifically as follows: ; It is important to understand that Indicates the device voltage, Represents the ADC digital value, represents the reference voltage (full-scale voltage of ADC), Indicates the resolution of the ADC (for example, a 10-bit ADC, N=1024). For current conversion, the current sensor usually converts the current signal into a voltage signal proportional to the actual current and performs signal conditioning and analog-to-digital conversion to obtain the corresponding ADC digital value. The ADC digital value is then substituted into the current conversion formula to obtain the current value, i.e., the device current. The current conversion formula is as follows: ; It is important to understand that Indicates the device voltage, Represents the ADC digital value, represents the reference voltage, Indicates the resolution of the ADC, Represents the proportional constant of the current sensor; by accurately and in real time obtaining the device voltage and device current, it is helpful to more effectively evaluate the power demand of the device.

[0028] Furthermore, the specific process of obtaining the equipment power demand assessment index is as follows: number the on-board power equipment, obtain reference equipment data from a preset database, the reference equipment data includes equipment standard voltage and equipment standard current, the equipment standard voltage represents the voltage value that enables the on-board power equipment to complete normal operation, and the equipment standard current represents the current value that enables the on-board power equipment to complete normal operation; based on the acquired equipment power data and the reference equipment data, the equipment power demand assessment index is obtained, and the equipment power demand assessment index is calculated using the following formula: ; In the formula, n represents the number of the on-board electrical equipment. , N represents the total number of on-board electrical equipment, Indicates the device voltage of the nth on-board electrical device, Indicates the standard voltage of the nth on-board electrical equipment. Indicates the equipment current of the nth on-board electrical equipment, Indicates the standard current of the nth on-board electrical equipment. represents the equipment power demand assessment index of the nth vehicle-mounted electrical equipment, and e represents a natural constant.

[0029] In this embodiment, the algorithm combines the equipment power consumption data and the reference equipment data for comprehensive analysis to obtain the equipment power consumption demand assessment index, and the independent variables equipment voltage and equipment current have different effects on the dependent variable equipment power consumption demand assessment index in different situations, which are specifically divided into four situations; among them, the first situation is that the equipment voltage is less than the equipment standard voltage and the equipment current is less than the equipment standard current. As the equipment voltage increases and the equipment current increases, the equipment power consumption demand assessment index decreases; the second situation is that the equipment voltage is not less than the equipment standard voltage and the equipment current is not less than the equipment standard current. As the equipment voltage increases, the equipment power consumption demand assessment index decreases, and as the equipment current increases, the equipment power consumption demand assessment index increases. The number increases; the third case is that the equipment voltage is lower than the equipment standard voltage and the equipment current is not lower than the equipment standard current. As the equipment voltage increases, the equipment power demand assessment index decreases, and as the equipment current increases, the equipment power demand assessment index increases; the fourth case is that the equipment voltage is not lower than the equipment standard voltage and the equipment current is lower than the equipment standard current. As the equipment voltage increases, the equipment power demand assessment index decreases, and as the equipment current increases, the equipment power demand assessment index decreases; the power demand assessment of on-board electrical equipment through the equipment power demand assessment index realizes the assessment of the power priority of on-board electrical equipment according to the actual emergency situation, which is helpful to the accurate allocation of emergency power supply.

[0030] Specifically, the reference device data is obtained from a preset database. In a specific embodiment, the device standard voltage and the device standard current are obtained by consulting the device specification of the vehicle-mounted electrical device. For example, by consulting the device specification of a vehicle-mounted audio system from Pioneer, the product model Pioneer DEH-S4000BT, it can be obtained that the device standard voltage is 12V and the device standard current is 2A.

[0031] Furthermore, the specific process of comparing the equipment power demand assessment index with the equipment power demand assessment interval obtained from the preset database is as follows: the equipment power demand assessment interval includes a first power assessment interval, a second power assessment interval, a third power assessment interval and a fourth power assessment interval, and the emergency power supply priority includes a first emergency power supply priority, a second emergency power supply priority, a third emergency power supply priority and a fourth emergency power supply priority. The higher the emergency power supply priority, the more priority the power supply control provides for the corresponding on-board power equipment. If the equipment power demand assessment index belongs to the first power assessment interval, the preset power supply priority of the corresponding on-board power equipment is adjusted to the first emergency power supply priority. If only a single on-board power equipment belongs to the first emergency power supply priority, the on-board power equipment is supplied with power according to the first emergency power supply priority. Otherwise, the on-board power equipment is supplied with power according to the preset power supply priority. If the equipment power demand assessment index belongs to the second power assessment interval, the current The preset power supply priority of the on-board electrical equipment is adjusted to the second emergency power supply priority. If only a single on-board electrical equipment belongs to the second emergency power supply priority, the on-board electrical equipment is supplied with electricity according to the second emergency power supply priority, otherwise the on-board electrical equipment is supplied with electricity according to the preset power supply priority; if the equipment power demand assessment index belongs to the third power assessment interval, the preset power supply priority of the current on-board electrical equipment is adjusted to the third emergency power supply priority. If only a single on-board electrical equipment belongs to the third emergency power supply priority, the on-board electrical equipment is supplied with electricity according to the third emergency power supply priority, otherwise the on-board electrical equipment is supplied with electricity according to the preset power supply priority; the preset power supply priority of the current on-board electrical equipment is adjusted to the fourth emergency power supply priority. If only a single on-board electrical equipment belongs to the fourth emergency power supply priority, the on-board electrical equipment is supplied with electricity according to the fourth emergency power supply priority, otherwise the power supply control supplies power to the on-board electrical equipment according to the preset power supply priority.

[0032] In this embodiment, taking into account the task requirements and importance of the on-board electrical equipment, the power consumption priority of the on-board electrical equipment is divided into four levels of preset power supply priorities. The equipment with the first level of preset power supply priority is critical life support and safety equipment, which is essential to personnel safety and the basic operation of the vehicle, such as: navigation and positioning system, emergency lighting system and braking system, etc.; the equipment with the second level of preset power supply priority is mission-critical equipment, which is essential to the completion of the current task, such as air conditioning and ventilation system in hot weather; the equipment with the third level of preset power supply priority is auxiliary and comfort equipment, which is mainly used to improve comfort and operational convenience, such as entertainment system and car refrigerator, etc.; the equipment with the fourth level of preset power supply priority is non-essential equipment, which has no direct impact on the basic functions and task execution of the vehicle, and is mainly used to enhance the additional functions of the vehicle, such as interior decorative lights and non-critical USB interfaces, etc. The specific preset power supply priority varies according to the situation and the specific setting varies from person to person.

[0033] Specifically, the vehicle-mounted electrical equipment can be powered according to the emergency power supply priority. The intelligent power management method can be used to realize the power supply of each vehicle-mounted electrical equipment. According to the power demand evaluation index of different equipment, the emergency power supply priority of the vehicle-mounted electrical equipment is dynamically adjusted, and the power resources are allocated to the required equipment according to the emergency power supply priority, ensuring that in the event of power shortage or emergency, important equipment can obtain power supply first; and by adjusting the preset power supply priority of the equipment, the power control can quickly respond to the changing power demand situation, especially in an emergency, giving priority to ensuring the continuous operation of important equipment; the method of this embodiment can dynamically adjust the power supply priority, select the power supply strategy according to the power demand of the equipment, and avoid power waste or insufficient resources. For example, when it is in hot weather, the driver has a relatively large demand for the use of air conditioning, so the vehicle-mounted air conditioner is in operation for a long time. At this time, it is detected that the power consumption priority of the air conditioner is the second emergency power supply priority, while in cool weather, the demand for the use of air conditioning is greatly reduced. At this time, it is detected that the power consumption priority of the vehicle air conditioner may be reduced to the fourth emergency power supply priority.

[0034] Specifically, the equipment power demand assessment interval is obtained from a preset database. In a specific embodiment, the equipment power demand assessment interval is set according to the standard of emergency power supply priority of the on-board electrical equipment in a specific emergency situation. For example, assuming that when the equipment power demand assessment index is not less than 0.9, it is considered that the on-board electrical equipment has reached the minimum standard of the first emergency power supply priority, and the maximum value of the equipment power demand assessment index is 1, then [0.9, 1] is set as the first power evaluation interval, when the equipment power demand assessment index is not less than 0.6, it is considered that the on-board electrical equipment has reached the minimum standard of the second emergency power supply priority, then [0.6, 0.9) is set as the second power evaluation interval, when the equipment power demand assessment index is not less than 0.3, it is considered that the on-board electrical equipment has reached the minimum standard of the third emergency power supply priority, then [0.3, 0.6) is set as the third power evaluation interval, when the equipment power demand assessment index is less than 0.3, it is considered that the on-board electrical equipment is a on-board electrical equipment of the fourth emergency power supply priority, then [0, 0.3) is set as the fourth power evaluation interval.

[0035] Furthermore, the process of acquiring power supply data is as follows: obtain the battery capacity and rated voltage of the emergency power supply by referring to the equipment specifications, and substitute the battery capacity and rated voltage into the battery capacity formula to obtain the initial total power of the power supply; obtain the remaining power of the power supply through the emergency power supply power indicator light; measure the temperature of the power supply in real time through the temperature sensor to obtain the power supply temperature; measure the vibration of the vehicle in real time through the vibration sensor to obtain the vibration frequency; the power supply temperature is used to determine whether the temperature of the power supply can meet the normal operation of the emergency power supply, and the vibration frequency is used to determine the road conditions on which the vehicle is traveling; the power supply data includes the initial total power of the power supply, the remaining power of the power supply, the power supply temperature and the vibration frequency.

[0036] In this embodiment, in order to accurately detect the vibration of the vehicle, the installation position of the vibration sensor is crucial. The most common installation positions are the wheel suspension system and the central part of the vehicle chassis. In addition, the method of this embodiment covers multiple key parameters of the emergency power supply, such as the initial total power of the emergency power supply, the remaining power of the power supply, the power supply temperature, and the vibration frequency of the vehicle, so as to achieve a comprehensive evaluation of the state and environmental conditions of the emergency power supply, and ensure the effectiveness and safety in practical applications. Among them, the battery capacity formula is as follows: ; It is important to understand that Ampere-hour (Ah for short) means the amount of current that a battery can provide at a specific voltage multiplied by time. For example, 1 ampere-hour means that the battery can provide 1 ampere of current in 1 hour. Indicates the standard voltage value of the emergency power supply battery, usually the output voltage of the battery under standard operating conditions. Indicates the initial total power of the power supply.

[0037] Furthermore, the temperature of the power supply is obtained by measuring the temperature of the power supply in real time through a temperature sensor, and then it also includes: obtaining the emergency power supply working temperature range from a preset database, the emergency power supply working temperature range represents the temperature range of the emergency power supply, and the emergency power supply working temperature range includes a low-temperature working temperature range, a safe working temperature range and a high-temperature working temperature range; comparing the power supply temperature with the emergency power supply working temperature range: if the power supply temperature belongs to the low-temperature working temperature range, a low-temperature warning is issued to the power supply user and the user is prompted to stop using the emergency power supply to avoid further damage to the emergency power supply; if the power supply temperature belongs to the high-temperature working temperature range, a high-temperature warning is issued to the power supply user and the use of the emergency power supply is forced to stop to prevent safety hazards; if the power supply temperature belongs to the safe working temperature range, the power supply evaluation index continues to be obtained.

[0038] In this embodiment, the safe working temperature interval is taken as a reference, and the interval on the left side of the safe working temperature interval, that is, the interval below the minimum value of the safe working temperature interval, is considered to be the low-temperature working temperature interval, and the interval on the right side of the safe working temperature interval, that is, the interval above the maximum value of the safe working temperature interval, is considered to be the high-temperature working temperature interval. By monitoring the power supply temperature in real time and comparing it with the preset working temperature interval, temperature anomalies can be identified in time, thereby reducing safety hazards such as fire and explosion caused by excessively high temperature, and power supply damage or failure caused by excessively low temperature. Among them, the emergency power supply working temperature interval can be obtained by referring to the specification provided by the emergency power supply manufacturer. For example, the optimal working temperature of the on-board emergency power supply of BYD product model BYD 48V LiFePO4 Battery Pack is 10 degrees Celsius to 45 degrees Celsius, so [10, 45] can be used as the safe working temperature interval, [- , 10) can be used as low temperature working temperature range, (45, + ] can be used as a high temperature operating temperature range.

[0039] Furthermore, the process of obtaining the power supply evaluation index is as follows: obtaining power supply reference data from a preset database, the power supply reference data including power supply aging influence factor, road condition influence factor, vibration frequency threshold and reference power supply temperature, the power supply aging influence factor is used to correct the influence of power supply aging on the emergency power supply capacity, the road condition influence factor is used to correct the influence of road condition on the emergency power supply capacity, the vibration frequency threshold is used to judge the road condition on which the current vehicle is traveling, and the reference power supply temperature indicates the optimal temperature at which the emergency power supply can maintain normal operation; obtaining the power supply evaluation index based on the obtained power supply data and the power supply reference data, and the power supply evaluation index is calculated using the following formula: ; In the formula, Indicates the remaining power of the power supply. Indicates the initial total power of the power supply. Indicates the power supply temperature, represents the reference power supply temperature, represents the vibration frequency, represents the vibration frequency threshold, Indicates the power aging influence factor, represents the road condition influencing factor, represents the power supply evaluation index, and e represents a natural constant.

[0040] In this embodiment, the algorithm combines the power supply data and the power reference data for comprehensive analysis to obtain the power supply evaluation index, and because of the different vibration frequencies, different algorithms correspond to two situations; wherein, in the first situation, the vibration frequency is not less than the vibration frequency threshold, indicating that the vehicle may be traveling on a road with poor road conditions, so it is necessary to consider the impact of road conditions on the emergency power supply, and in the second situation, the vibration frequency is less than the vibration frequency threshold, indicating that the vehicle may be traveling on a flat road, so it is not necessary to consider the impact of road conditions on the emergency power supply; wherein, as the absolute value of the difference between the independent variable power supply temperature and the reference power supply temperature increases, the dependent variable power supply evaluation index decreases accordingly, and as the independent variable power supply residual current increases, the dependent variable power supply evaluation index increases accordingly; the emergency power supply capacity is effectively evaluated through the power supply evaluation index, which is conducive to the reasonable allocation of electricity under different power conditions.

[0041] Specifically, Figure 2 As shown in the figure, it is a schematic diagram of the change of the power supply evaluation index in the first case, where it is assumed that the power supply aging factor is 0.3, the road condition influence factor is 0.3, the total initial power of the power supply For 100Ah, reference power supply temperature It is 25 degrees Celsius. It can be seen from the figure that when the remaining power of the power supply gradually increases, the image shows a gradually upward trend. It can be seen that the remaining power of the power supply is positively correlated with the power supply evaluation index; however, when the power supply temperature is closer to the reference power supply temperature, that is, the absolute value of the difference between the power supply temperature and the reference power supply temperature gradually decreases, the corresponding vertical coordinate value in the image is larger. It can be seen that the absolute value of the difference between the power supply temperature and the reference power supply temperature is negatively correlated with the power supply evaluation index.

[0042] Specifically, as shown in Table 1, it is a table of power supply evaluation index changes in the second case, where it is assumed that the power supply aging factor is 0.3, the total initial power of the power supply For 100Ah, reference power supply temperature The temperature is 25 degrees Celsius, and the power supply evaluation index change data table is obtained by combining the power supply temperature and the remaining power of the power supply, as shown in Table 1: Table 1 Power supply evaluation index change data table It can be seen from the table that when the remaining power of the power supply remains unchanged and the power supply temperature is closer to the reference power supply temperature of 25 degrees Celsius, the greater the power supply evaluation index is. For example, in the first and second rows of data in the table, the remaining power of the power supply is 80Ah, but the power supply temperature of 20 degrees Celsius in the second row is closer to the reference power supply temperature of 25 degrees Celsius than the power supply temperature of 10 degrees Celsius in the first row, and the power supply evaluation index of 0.86 in the second row is greater than the power supply evaluation index of 0.77 in the first row; when the power supply temperature remains unchanged, as the remaining power of the power supply decreases, the power supply evaluation index also decreases. For example, in the fourth and fifth rows of data in the table, the power supply temperature is 30 degrees Celsius, but as the remaining power of 50Ah in the fourth row decreases to the remaining power of 40Ah in the fifth row, the power supply evaluation index of 0.60 in the fourth row also decreases to the power supply evaluation index of 0.49 in the fifth row; it can be obtained that when the power supply temperature is closer to the reference power supply temperature and the remaining power of the power supply is higher, the power supply capacity of the emergency power supply is stronger.

[0043] Specifically, the reference power supply temperature is obtained from a preset database. In a specific embodiment, the reference power supply temperature can be obtained by measuring the performance of the emergency power supply battery at different temperatures in a laboratory environment, and finding a temperature that enables the emergency power supply battery to maintain optimal performance and setting it as the reference power supply temperature.

[0044] Specifically, the vibration frequency threshold is obtained from a preset database. In a specific embodiment, by simulating different vibration frequencies in a laboratory and observing the impact on the power supply stability of the emergency power supply, a vibration frequency whose impact on the power supply capacity of the emergency power supply is unacceptable to the experimental requirements is determined, and the vibration frequency is used as the vibration frequency threshold.

[0045] Specifically, when the power supply aging impact factor is used, the power supply aging impact factor corresponding to the emergency power supply usage time can be directly obtained from the preset database, and the corresponding relationship can be a preset mapping relationship. For example, the emergency power supply usage time corresponding to the power supply aging impact factor and the preset power supply aging impact factor in the preset database form a mapping set, and the real-time emergency power supply usage time is input into the mapping set to obtain the corresponding power supply aging impact factor, and the mapping relationship is one-to-one or many-to-one.

[0046] Specifically, when the road condition impact factor is used, the road condition impact factor corresponding to the measured vibration frequency can be directly obtained from the preset database, and the corresponding relationship can be a pre-set mapping relationship. For example, the vibration frequency corresponding to the road condition impact factor and the road condition impact factor preset in the preset database form a mapping set, and the real-time vibration frequency is input into the mapping set to obtain the corresponding road condition impact factor, and the mapping relationship is one-to-one or many-to-one.

[0047] Furthermore, the specific steps of comparing the power supply evaluation index with the power supply evaluation interval obtained from a preset database are as follows: the power supply evaluation interval includes a first power supply evaluation interval, a second power supply evaluation interval, a third power supply evaluation interval and a fourth power supply evaluation interval; step one, if the power supply evaluation index belongs to the first power supply evaluation interval, then based on the first button selection of the power user, it is determined whether to supply power to all vehicle-mounted electrical equipment with emergency power supply priority. The first button selection is used to determine whether the power user provides power to all vehicle-mounted electrical equipment with emergency power supply priority. If the power user clicks yes, power is provided to all vehicle-mounted electrical equipment with emergency power supply priority. If the power user clicks no, no power supply adjustment measures are taken; step two, if the power supply evaluation index belongs to the second power supply evaluation interval, then based on the second button selection of the power user, it is determined whether to supply power to the vehicle-mounted electrical equipment with the fourth emergency power supply priority. The second button selection is used to determine whether the power user stops supplying power to the vehicle-mounted electrical equipment with the fourth emergency power supply priority. If the power user clicks no, no power supply adjustment measures are taken. If the power user clicks yes, power supply to the on-board power equipment with the fourth emergency power supply priority will be stopped. If the power user clicks no, no power supply adjustment measures will be taken. Step three, if the power supply evaluation index belongs to the third power supply evaluation interval, based on the third button selection of the power user, it is determined whether to supply power to the on-board power equipment with the third emergency power supply priority. The third button selection is used to determine whether the power user stops supplying power to the on-board power equipment with the third emergency power supply priority. If the power user clicks yes, power supply to the on-board power equipment with the fourth emergency power supply priority will be stopped. If the power user clicks no, no power supply adjustment measures will be taken. Step four, based on the fourth button selection of the power user, it is determined whether to supply power to the on-board power equipment with the second emergency power supply priority. The third button selection is used to determine whether the power user stops supplying power to the on-board power equipment with the second emergency power supply priority. If the power user clicks yes, power supply to the on-board power equipment with the fourth emergency power supply priority will be stopped. If the power user clicks no, no power supply adjustment measures will be taken.

[0048] In this embodiment, four power supply evaluation intervals correspond to four emergency power supply priorities. Through the button selection judgment of the power user, the emergency power supply is intelligently allocated to the vehicle-mounted electrical equipment of different priorities. This method can help manage the distribution of power in different scenarios, ensuring that key equipment can be given priority support when power is limited. At the same time, it allows power users to make adjustments according to actual conditions, effectively reducing the unreasonable distribution of power supply due to misoperation or misjudgment.

[0049] Specifically, the power supply evaluation interval is obtained from a preset database. In a specific embodiment, the power supply evaluation interval is set according to the requirements of on-board electrical equipment with different emergency power supply priorities in a specific emergency situation. For example, assuming that when the power supply evaluation index is greater than 0.85, it is considered that the emergency power supply capacity can meet the power demand of all on-board electrical equipment, then [0.85, + ] is the first electricity consumption evaluation interval. When the power supply evaluation index is not less than 0.60 and less than 0.85, it is considered that the emergency power supply capacity can meet the power demand of on-board electrical equipment except the fourth emergency power supply priority, and [0.60, 0.85) is considered to be the second electricity consumption evaluation interval. When the power supply evaluation index is not less than 0.30 and less than 0.60, it is considered that the emergency power supply capacity can meet the power demand of on-board electrical equipment except the third emergency power supply priority and the fourth emergency power supply priority, and [0.30, 0.60) is considered to be the third electricity consumption evaluation interval. When the power supply evaluation index is less than 0.30, it is considered that the emergency power supply capacity can only meet the power demand of on-board electrical equipment of the first emergency power supply priority, and [0.00, 0.30) is considered to be the fourth electricity consumption evaluation interval.

[0050] Furthermore, the vehicle-mounted mobile emergency power supply control method also includes: when the remaining power of the power supply is lower than a preset power supply threshold and no connected power supply is detected, a power off reminder is sent to the power supply user, and the power off reminder is used to inform the power supply user that the emergency power supply is about to be cut off; if a request for help from the power supply user is detected, a help message is sent immediately, and the preset power supply threshold indicates a warning value that the emergency power supply is about to be cut off, and the help message includes the current vehicle location information, power consumption and help content.

[0051] In this embodiment, when the remaining power of the emergency power supply is lower than the preset power threshold and is not connected to an external power supply, the system automatically sends a power-off reminder to the power user. This function can warn the power user in advance to prevent sudden power outages due to power exhaustion, thereby reducing the impact on important equipment and tasks; wherein the preset power threshold is obtained from a preset database, and the preset power threshold is the maximum value of the remaining power of the emergency power supply that is insufficient to provide sufficient power to continue to ensure the maximum value of the remaining power of the on-board electrical equipment. For example, assuming that when the remaining power of the emergency power supply is 3Ah, the power is insufficient to support any on-board electrical equipment, then 3Ah is the preset power threshold.

It is used to adjust the preset power supply priority of the current on-board electrical equipment to adapt to the current emergency situation. The preset power supply priority is preset according to the current task requirements of the on-board electrical equipment. The emergency power supply priority represents the priority of the preset power supply priority of the on-board electrical equipment adjusted according to the actual emergency task requirements; the power supply comprehensive evaluation and adjustment module is used to monitor the power consumption and impact of the emergency power supply through the power supply data acquisition equipment to obtain power supply data, and obtain the power supply evaluation index based on the power supply data and the power supply reference data obtained from the preset database, and compare the power supply evaluation index with the power supply evaluation interval obtained from the preset database to take power supply adjustment measures. The power supply data acquisition equipment is used to collect data related to the power supply capacity. The power supply evaluation index is used to quantify the power supply capacity of the emergency power supply under the current circumstances. The power supply adjustment measures represent providing different power supplies to on-board electrical equipment of different priorities according to the actual power situation of the current emergency power supply.

[0053] In this embodiment, the equipment data analysis module can quantify the power demand of on-board electrical equipment through precise power demand assessment, ensuring that the system has an accurate understanding of the power demand of different equipment; the equipment priority adjustment module dynamically adjusts the power supply priority of the on-board equipment, so that the system can optimize power distribution according to real-time demand, so that key equipment can be given priority power supply in emergency situations, thereby improving the reliability of the system; the power comprehensive evaluation and adjustment module ensures that the system can respond flexibly under different power conditions and maximize the optimization of power utilization efficiency; through the collaborative work of the above modules, the system can automatically adjust the equipment priority and power distribution strategy according to real-time data and preset reference standards, so as to respond quickly in emergency situations, which not only improves the flexibility of the system, but also can ensure the continuous operation of equipment in different emergency scenarios and enhance the overall emergency handling capabilities.
