Description

Technical Field

[0001] This invention relates to the field of smart charging pile technology, and more specifically, to a monitoring and early warning method and system for smart charging piles. Background Technology

[0002] A charging pile is a power replenishment device for electric vehicles, similar in function to a gas pump at a gas station. It can be fixed to the ground or wall and installed in public buildings (charging stations, shopping malls, public parking lots, etc.) and residential parking lots. It can charge various models of electric vehicles by adjusting the voltage and current. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally offer two charging methods: regular charging and fast charging. Users can use a specific charging card to swipe on the human-machine interface provided by the charging pile to perform corresponding charging operations and print out payment data. The charging pile display screen shows data such as charging amount, cost, and charging time.

[0003] In the existing charging pile technology system, although charging piles have provided crucial infrastructure support for the popularization of electric vehicles, their function is often limited to basic power transmission, that is, only able to safely deliver electricity from the grid to electric vehicles for charging. This single "plug and charge" mode meets basic needs in terms of convenience, but falls short in terms of intelligence, safety, and user experience. Specifically, existing charging piles generally lack monitoring and early warning functions, which constitutes a significant safety hazard. When electric vehicles encounter potential safety problems during charging, such as battery overheating, abnormal current, loose charging interfaces, or short circuits, these traditional charging piles often cannot detect and react in time. This "blind spot" may not only lead to vehicle damage, but also potentially cause serious safety accidents such as fires and electric shocks, posing a direct threat to personal safety.

[0004] Therefore, it is necessary to provide a monitoring and early warning method and system for smart charging piles to solve the problem that existing charging piles lack monitoring and early warning functions, which poses safety hazards when vehicles are charging. Summary of the Invention

[0005] In view of this, the present invention proposes a monitoring and early warning method and system for smart charging piles, aiming to solve the problem that charging piles lack monitoring and early warning functions, which poses safety hazards when vehicles are charging.

[0006] On one hand, this invention proposes a monitoring and early warning method for smart charging piles, including:

[0007] Collect real-time temperature data of the smart charging pile and obtain the temperature change curve of the smart charging pile. Calculate the safety index corresponding to the current temperature of the smart charging pile and make a preliminary judgment on the safety status of the smart charging pile based on the safety index.

[0008] Real-time ambient temperature data of the location of the smart charging pile is collected, and an ambient temperature change curve is obtained. The safety status of the smart charging pile is classified by combining the ambient temperature change curve and the temperature change curve of the smart charging pile.

[0009] The working parameters of the smart charging pile are collected, and the working status level of the smart charging pile is determined according to the working parameters. The working parameters include the power output per unit time, the working time per day, and the working years.

[0010] Based on the adjusted safety status level and working status level of the smart charging pile, a final hazard warning is issued for the smart charging pile.

[0011] Furthermore, the process of collecting real-time temperature data of the smart charging pile, obtaining a temperature change curve of the smart charging pile, calculating a safety index corresponding to the current temperature of the smart charging pile, and making a preliminary judgment on the safety status of the smart charging pile based on the safety index includes:

[0012] The safety index = (maximum permissible temperature - current temperature) / maximum permissible temperature;

[0013] A minimum safety index value is preset, and the safety index value corresponding to the current temperature is calculated. If the safety index value corresponding to the current temperature is greater than or equal to the minimum safety index value, the safety status of the smart charging pile is initially determined to be safe.

[0014] If the safety index value corresponding to the current temperature of the smart charging pile is lower than the minimum safety index value, then the safety status of the smart charging pile is preliminarily determined to be unsafe.

[0015] Furthermore, when collecting real-time ambient temperature data of the location of the smart charging pile and obtaining an ambient temperature change curve, and combining the ambient temperature change curve and the temperature change curve of the smart charging pile to classify the safety status of the smart charging pile, the following steps are included:

[0016] The safety status levels of the smart charging pile are pre-set from high to low as Level 1 safety status, Level 2 safety status, and Level 3 safety status, and the unsafe status levels are pre-set from high to low as Level 1 unsafe status, Level 2 unsafe status, and Level 3 unsafe status;

[0017] If the safety index value corresponding to the current temperature is greater than or equal to the minimum safety index value, then the safety status of the smart charging pile is preliminarily determined to be a level one safety status.

[0018] If the safety index corresponding to the current temperature of the smart charging pile is lower than the minimum safety index value, the safety status of the smart charging pile is preliminarily determined to be a level one unsafe state.

[0019] If the temperature of the smart charging pile is on an upward trend while the ambient temperature change curve is on a downward trend, it is determined that the heat dissipation of the smart charging pile is problematic, and the safety status level of the smart charging pile is downgraded by one level.

[0020] If the temperature of the smart charging pile is on an upward trend, and the ambient temperature change curve is also on an upward trend, it is determined that the temperature of the smart charging pile is affected by the ambient temperature, and the safety status level of the smart charging pile is initially maintained unchanged.

[0021] Furthermore, if the temperature of the smart charging pile is trending upwards, and the ambient temperature change curve is also trending upwards, then it is determined that the temperature of the smart charging pile is affected by the ambient temperature. After initially maintaining the safety status level of the smart charging pile unchanged, the process includes:

[0022] The standard temperature rise value of the smart charging pile when the ambient temperature rises by one degree Celsius is preset, and the temperature rise value of the smart charging pile when the ambient temperature rises by one degree Celsius is calculated.

[0023] If the temperature rise is less than or equal to the standard temperature rise, the safety status level of the smart charging pile remains unchanged.

[0024] If the temperature rise is greater than the standard temperature rise, the safety status level of the smart charging pile is determined to be downgraded by one level.

[0025] Furthermore, when collecting the operating parameters of the smart charging pile and determining the operating status level of the smart charging pile based on the operating parameters, the process includes:

[0026] Set the standard power output per unit time of the smart charging pile, and make a preliminary judgment on the working status of the smart charging pile based on the standard power output per unit time of the smart charging pile.

[0027] If the power output per unit time of the smart charging pile is greater than or equal to the standard power output per unit time, the working status level of the smart charging pile is preliminarily determined to be good.

[0028] If the power output per unit time of the smart charging pile is less than the standard power output per unit time, the working status level of the smart charging pile is initially determined to be poor.

[0029] Furthermore, if the power output per unit time of the smart charging pile is less than the standard power output per unit time, then after initially determining that the working status level of the smart charging pile is poor, the following steps are included:

[0030] If the daily working hours of the smart charging pile exceed eight hours, the working status level of the smart charging pile will be adjusted to the worst.

[0031] If the daily working time of the smart charging pile does not exceed eight hours, collect and analyze the comparison data of the power output per unit time of the smart charging pile and the same batch of smart charging piles to determine whether the working status of the smart charging pile is abnormal.

[0032] The working status levels of the smart charging piles, from high to low, are good, poor, and very poor.

[0033] Furthermore, if the daily working hours of the smart charging pile do not exceed eight hours, when collecting and analyzing comparative data on the unit-time power output of the smart charging pile and other smart charging piles in the same batch to determine whether the working status of the smart charging pile is abnormal, the following steps are included:

[0034] Calculate the average power output per unit time of the same batch of smart charging piles, and compare the power output per unit time of the target smart charging pile with the average power output per unit time of the same batch of smart charging piles; if the duration of the target smart charging pile is lower than the average, it is determined that the working status of the smart charging pile is abnormal.

[0035] When it is determined that the working status of the smart charging pile is abnormal, a severe danger warning will be issued directly.

[0036] Furthermore, after initially determining the working status level of the smart charging pile as poor if its power output per unit time is less than the standard power output per unit time, the method further includes:

[0037] The working years of the smart charging pile are collected, and the working status level of the smart charging pile is adjusted accordingly;

[0038] If the working years of the smart charging pile are less than or equal to the standard working years, the working status level of the smart charging pile will be downgraded by one level.

[0039] If the service life of the smart charging pile is greater than the standard service life, the working status level of the smart charging pile will not be adjusted.

[0040] Furthermore, when issuing a final hazard warning for the smart charging pile based on the adjusted safety and operational status levels, the following steps are included:

[0041] If the smart charging pile is in an unsafe state and its operating status is either poor or extremely poor, a severe danger warning will be issued for the smart charging pile.

[0042] If the smart charging pile is in an unsafe state, but its working status is good, a moderate danger warning will be issued for the smart charging pile.

[0043] If the smart charging pile is in a safe state and its working state is either poor or extremely poor, a moderate danger warning will be issued for the smart charging pile.

[0044] If the smart charging pile is in either a level 2 or level 3 safety state, and the smart charging pile is in good working condition, a mild danger warning will be issued for the smart charging pile.

[0045] Otherwise, no danger warning will be issued;

[0046] The final danger warning levels are, from highest to lowest, severe danger warning, moderate danger warning, and mild danger warning.

[0047] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0048] By comprehensively collecting real-time temperature data from smart charging piles and their surrounding environment, and plotting corresponding temperature change curves, we can not only accurately grasp the operating status of the charging piles but also effectively assess their safety index at the current temperature, thus achieving a preliminary and accurate judgment of their safety status. Furthermore, by combining this with changes in ambient temperature, we can dynamically adjust the safety status, ensuring the flexibility and accuracy of early warnings. Simultaneously, by collecting and analyzing the operating parameters of smart charging piles, we can scientifically assess their operating status level, providing crucial information for subsequent maintenance and management. Finally, by combining the adjusted safety status with the operating status level, we can issue hazard warnings, significantly improving the efficiency of smart charging pile safety management, reducing potential safety hazards, and ensuring the safety and convenience of users' charging.

[0049] On the other hand, this application also provides a monitoring and early warning system for smart charging piles, including:

[0050] The safety status judgment module collects real-time temperature data of the smart charging pile and obtains the temperature change curve of the smart charging pile. It calculates the safety index corresponding to the current temperature of the smart charging pile and makes a preliminary judgment on the safety status of the smart charging pile based on the safety index.

[0051] The safety status adjustment module collects real-time ambient temperature data of the location of the smart charging pile and obtains an ambient temperature change curve. It then combines the ambient temperature change curve and the temperature change curve of the smart charging pile to classify the safety status of the smart charging pile.

[0052] The working status determination module collects the working parameters of the smart charging pile and determines the working status level of the smart charging pile based on the working parameters. The working parameters include the power output per unit time, the working duration per day, and the working years.

[0053] The danger warning module, in conjunction with the adjusted safety status level and working status level of the smart charging pile, provides a final danger warning for the smart charging pile.

[0054] It is understood that the monitoring and early warning method and system for smart charging piles provided in this application have the same beneficial effects, and will not be described in detail here. Attached Figure Description

It should be noted that, unless otherwise specified, embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0059] In some embodiments of this application, see Figure 1 As shown, this embodiment provides a monitoring and early warning method for smart charging piles, including the following steps:

[0060] S100. Collect real-time temperature data of the smart charging pile and obtain the temperature change curve of the smart charging pile. Calculate the safety index corresponding to the current temperature of the smart charging pile and make a preliminary judgment on the safety status of the smart charging pile based on the safety index.

[0061] S200. Collect real-time ambient temperature data of the location of the smart charging pile and obtain an ambient temperature change curve. Combine the ambient temperature change curve and the temperature change curve of the smart charging pile to classify the safety status of the smart charging pile.

[0062] S300. Collect the working parameters of the smart charging pile, and determine the working status level of the smart charging pile based on the working parameters. The working parameters include the power output per unit time, the working time per day, and the working years.

[0063] S400. Combining the adjusted safety status level and working status level of the smart charging pile, a final danger warning is issued for the smart charging pile.

[0064] Understandably, by comprehensively collecting real-time temperature data from smart charging piles and their surrounding environment, and plotting corresponding temperature change curves, it is possible not only to accurately grasp the operating status of the charging piles but also to effectively assess their safety index at the current temperature, thus achieving a preliminary and accurate judgment of their safety status. Furthermore, by combining this with changes in ambient temperature, the safety status can be dynamically adjusted, ensuring the flexibility and accuracy of early warnings. Simultaneously, by collecting and analyzing the operating parameters of smart charging piles, their operating status level can be scientifically assessed, providing crucial information for subsequent maintenance and management. Finally, combining the adjusted safety status with the operating status level for hazard warnings greatly improves the efficiency of smart charging pile safety management, reduces potential safety hazards, and ensures the safety and convenience of users' charging.

[0065] In some embodiments of this application, the step of collecting real-time temperature data of the smart charging pile, obtaining a temperature change curve of the smart charging pile, calculating a safety index corresponding to the current temperature of the smart charging pile, and making a preliminary judgment on the safety status of the smart charging pile based on the safety index includes:

[0066] The safety index = (maximum permissible temperature - current temperature) / maximum permissible temperature;

[0067] A minimum safety index value is preset, and the safety index value corresponding to the current temperature is calculated. If the safety index value corresponding to the current temperature is greater than or equal to the minimum safety index value, the safety status of the smart charging pile is initially determined to be safe.

[0068] If the safety index value corresponding to the current temperature of the smart charging pile is lower than the minimum safety index value, then the safety status of the smart charging pile is preliminarily determined to be unsafe.

[0069] In some embodiments of this application, the step of collecting real-time ambient temperature data of the location of the smart charging pile and obtaining an ambient temperature change curve, and then classifying the safety status of the smart charging pile by combining the ambient temperature change curve and the temperature change curve of the smart charging pile, includes:

[0070] The safety status levels of the smart charging pile are pre-set from high to low as Level 1 safety status, Level 2 safety status, and Level 3 safety status, and the unsafe status levels are pre-set from high to low as Level 1 unsafe status, Level 2 unsafe status, and Level 3 unsafe status;

[0071] If the safety index value corresponding to the current temperature is greater than or equal to the minimum safety index value, then the safety status of the smart charging pile is preliminarily determined to be a level one safety status.

[0072] If the safety index corresponding to the current temperature of the smart charging pile is lower than the minimum safety index value, the safety status of the smart charging pile is preliminarily determined to be a level one unsafe state.

[0073] If the temperature of the smart charging pile is on an upward trend while the ambient temperature change curve is on a downward trend, it is determined that the heat dissipation of the smart charging pile is problematic, and the safety status level of the smart charging pile is downgraded by one level.

[0074] If the temperature of the smart charging pile is on an upward trend, and the ambient temperature change curve is also on an upward trend, it is determined that the temperature of the smart charging pile is affected by the ambient temperature, and the safety status level of the smart charging pile is initially maintained unchanged.

[0075] In some embodiments of this application, if the temperature of the smart charging pile is trending upwards and the ambient temperature change curve is also trending upwards, then it is determined that the temperature of the smart charging pile is affected by the ambient temperature. After initially maintaining the safety status level of the smart charging pile unchanged, the process includes:

[0076] The standard temperature rise value of the smart charging pile when the ambient temperature rises by one degree Celsius is preset, and the temperature rise value of the smart charging pile when the ambient temperature rises by one degree Celsius is calculated.

[0077] If the temperature rise is less than or equal to the standard temperature rise, the safety status level of the smart charging pile remains unchanged.

[0078] If the temperature rise is greater than the standard temperature rise, the safety status level of the smart charging pile is determined to be downgraded by one level.

[0079] Understandably, this application achieves accurate assessment and dynamic adjustment of the safety status of smart charging piles through real-time temperature monitoring and environmental change analysis. Utilizing a safety index calculation model, it compares the current temperature of the smart charging pile with the allowable temperature range to quickly determine its safety status, effectively preventing overheating risks. Simultaneously, by combining ambient temperature changes, it identifies differences in heat dissipation issues or environmental impacts of the smart charging pile, flexibly adjusting the safety status assessment to ensure the accuracy and real-time nature of the results. When the ambient temperature and the smart charging pile temperature rise synchronously, the comparison with preset standard temperature rise values ​​further refines the judgment logic of the safety status, effectively distinguishing between normal temperature changes and abnormal overheating situations. This provides timely and accurate early warning information for maintenance personnel, not only improving the safety management level of charging piles but also enhancing the user experience, providing a solid guarantee for the widespread application of new energy vehicles.

[0080] In some embodiments of this application, the step of collecting the operating parameters of the smart charging pile and determining the operating status level of the smart charging pile based on the operating parameters includes:

[0081] Set the standard power output per unit time of the smart charging pile, and make a preliminary judgment on the working status of the smart charging pile based on the standard power output per unit time of the smart charging pile.

[0082] If the power output per unit time of the smart charging pile is greater than or equal to the standard power output per unit time, the working status level of the smart charging pile is preliminarily determined to be good.

[0083] If the power output per unit time of the smart charging pile is less than the standard power output per unit time, the working status level of the smart charging pile is initially determined to be poor.

[0084] In some embodiments of this application, the step of initially determining the working status level of the smart charging pile as poor after the step of the smart charging pile's power output per unit time being less than the standard power output per unit time includes:

[0085] If the daily working hours of the smart charging pile exceed eight hours, the working status level of the smart charging pile will be adjusted to the worst.

[0086] If the daily working time of the smart charging pile does not exceed eight hours, collect and analyze the comparison data of the power output per unit time of the smart charging pile and the same batch of smart charging piles to determine whether the working status of the smart charging pile is abnormal.

[0087] The working status levels of the smart charging piles, from high to low, are good, poor, and very poor.

[0088] In some embodiments of this application, when the daily working hours of the smart charging pile do not exceed eight hours, collecting and analyzing comparative data on the unit-time power output of the smart charging pile and other smart charging piles in the same batch to determine whether the working status of the smart charging pile is abnormal includes:

[0089] Calculate the average power output per unit time of the same batch of smart charging piles, and compare the power output per unit time of the target smart charging pile with the average power output per unit time of the same batch of smart charging piles; if the duration of the target smart charging pile is lower than the average, it is determined that the working status of the smart charging pile is abnormal.

[0090] When it is determined that the working status of the smart charging pile is abnormal, a severe danger warning will be issued directly.

[0091] In some embodiments of this application, after initially determining the working status level of the smart charging pile as poor if the unit time power output of the smart charging pile is less than the unit time standard power output, the method further includes:

[0092] The working years of the smart charging pile are collected, and the working status level of the smart charging pile is adjusted accordingly;

[0093] If the working years of the smart charging pile are less than or equal to the standard working years, the working status level of the smart charging pile will be downgraded by one level.

[0094] If the service life of the smart charging pile is greater than the standard service life, the working status level of the smart charging pile will not be adjusted.

[0095] Understandably, the intelligent charging pile status assessment method in this application achieves a comprehensive and accurate assessment of the intelligent charging pile's working status by comprehensively considering multiple dimensions such as operating parameters, operating time, comparison with the same batch, and years of service. First, based on the power output per unit time, a preliminary assessment of the intelligent charging pile's performance status is made. Then, the assessment is further refined by combining the daily operating time to ensure the accuracy of the results. For charging piles in abnormal states, comparison with the same batch quickly identifies individual differences, promptly issuing severe danger warnings and effectively preventing potential failures. Furthermore, the introduction of the years of service factor allows for differentiated treatment of aging equipment, ensuring the fairness of the assessment while avoiding excessive intervention. This not only improves the operation and maintenance efficiency of intelligent charging piles but also extends the equipment's lifespan, providing strong support for the safe and reliable operation of new energy vehicle charging infrastructure and promoting the sustainable development of green travel.

[0096] In some embodiments of this application, when issuing a final hazard warning for the smart charging pile based on the adjusted safety status and operational status level of the smart charging pile, the following steps are included:

[0097] If the smart charging pile is in an unsafe state and its operating status is either poor or extremely poor, a severe danger warning will be issued for the smart charging pile.

[0098] If the smart charging pile is in an unsafe state, but its working status is good, a moderate danger warning will be issued for the smart charging pile.

[0099] If the smart charging pile is in a safe state and its working state is either poor or extremely poor, a moderate danger warning will be issued for the smart charging pile.

[0100] If the smart charging pile is in either a level 2 or level 3 safety state, and the smart charging pile is in good working condition, a mild danger warning will be issued for the smart charging pile.

[0101] Otherwise, no danger warning will be issued;

[0102] The final danger warning levels are, from highest to lowest, severe danger warning, moderate danger warning, and mild danger warning.

[0103] Understandably, this application improves the safety management level of smart charging piles by comprehensively considering their safety and operational status. It can promptly trigger severe or moderate hazard warnings when the safety or operational status of a smart charging pile deteriorates significantly, ensuring that maintenance personnel can respond quickly and address potential risks. Simultaneously, for smart charging piles whose safety status is not optimal but whose operational status is good, a mild warning is also issued, prompting attention and prevention. This tiered warning system not only avoids excessive intervention but also ensures that key risks are not overlooked, effectively balancing the sensitivity and practicality of safety monitoring and providing a solid guarantee for the long-term stable operation of charging facilities.

[0104] In summary, by comprehensively collecting real-time temperature data from both the smart charging pile and its surrounding environment, and plotting corresponding temperature change curves, we can not only accurately grasp the operating status of the charging pile but also effectively assess its safety index under the current temperature, thus achieving a preliminary and accurate judgment of its safety status. Furthermore, by combining this with changes in ambient temperature, we can dynamically adjust the safety status, ensuring the flexibility and accuracy of early warnings. Simultaneously, by collecting and analyzing the operating parameters of the smart charging pile, we can scientifically assess its operating status level, providing crucial information for subsequent maintenance and management. Finally, by combining the adjusted safety status with the operating status level for hazard warnings, we significantly improve the efficiency of smart charging pile safety management, reduce potential safety hazards, and ensure the safety and convenience of users' charging.

[0105] On the other hand, see Figure 2 As shown, this application also provides a monitoring and early warning system for smart charging piles, used to apply the above-mentioned monitoring and early warning method for smart charging piles, including:

[0106] The safety status judgment module is used to collect real-time temperature data of the smart charging pile, obtain the temperature change curve of the smart charging pile, calculate the safety index corresponding to the current temperature of the smart charging pile, and make a preliminary judgment on the safety status of the smart charging pile based on the safety index.

[0107] The safety status adjustment module is used to collect real-time ambient temperature data of the location of the smart charging pile and obtain an ambient temperature change curve. The module combines the ambient temperature change curve and the temperature change curve of the smart charging pile to adjust the safety status of the smart charging pile.

[0108] The working status determination module is used to collect the working parameters of the smart charging pile and determine the working status level of the smart charging pile based on the working parameters. The working parameters include the time required for full charging, the working time of the day, and the working years.

[0109] The hazard warning module is used to provide a final hazard warning for the smart charging pile by combining the adjusted safety status and working status level of the smart charging pile.

[0110] First, the safety status assessment module tracks temperature changes in smart charging piles in real time and calculates corresponding safety indices, enabling preliminary identification and early warning of potential safety hazards and enhancing the system's proactive defense capabilities. Next, the safety status adjustment module comprehensively considers ambient temperature factors and dynamically adjusts the safety status, ensuring the accuracy and timeliness of warnings and avoiding misjudgments or omissions due to single factors. Simultaneously, the working status assessment module collects and analyzes the working parameters of the smart charging piles to comprehensively evaluate their working status level, providing a scientific basis for equipment maintenance and performance optimization. This multi-dimensional and refined management helps extend the lifespan of smart charging piles and improve their operational efficiency. Finally, the hazard warning module combines the safety status adjustment results with the working status level to provide a final hazard warning, ensuring the comprehensiveness and accuracy of the warning information. This not only helps maintenance personnel respond quickly and address potential safety issues promptly but also effectively improves the user's charging experience and enhances their trust in smart charging facilities. In summary, the construction of this system achieves comprehensive, real-time, and intelligent safety management of smart charging piles, providing strong support for the sustainable development of the new energy vehicle industry.
