BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further described below in conjunction with the drawings and embodiments. In the drawings:

[0030] Figure 1 is a program flowchart of an embodiment of a charging pile control method of the present invention;

[0031] Figure 2 is a program flowchart of another embodiment of a charging pile control method of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] In order to have a clearer understanding of the technical features, objectives, and effects of the present invention, the specific embodiments of the present invention will now be described in detail with reference to the drawings.

[0033] As Figure 1 shown, an embodiment of a charging pile control method of the present invention is shown. In Figure 1 the embodiment of a charging pile control method of the present invention shown, the method includes the following steps: S1, generate the noise threshold and temperature threshold corresponding to the charging pile; S2, during the operation of the charging pile, obtain the noise information and temperature information corresponding to the charging pile; S3, adjust the working mode of the charging pile according to the relationship between the noise information and the noise threshold and the relationship between the temperature information and the temperature threshold.

[0034] Based on step S1, the corresponding noise threshold and temperature threshold of the charging pile can be obtained and stored. Among them, the noise threshold of the charging pile can be understood as the maximum noise value when the charging pile works without affecting the surrounding environment, and its unit is decibel. For example, if the corresponding noise threshold of a charging pile is set to 90 decibels, during the working process of the charging pile, it is necessary to control the working process of the charging pile so that the noise generated during the operation of the charging pile does not exceed 90 decibels. The specific value can be set according to needs. The temperature threshold of the charging pile refers to the threshold value that the temperature of the charging pile cannot exceed when it works normally. Its unit can be set to Celsius. For example, if the corresponding temperature threshold of a charging pile is set to 50 degrees Celsius, during the working process of the charging pile, it is necessary to control the working process of the charging pile so that the temperature during the operation of the charging pile does not exceed 50 °C. Among them, the specific data can be specifically set according to needs.

[0035] Based on step S2, when the charging pile is working, for example, when a user uses the charging pile to charge a device, the working temperature and working noise of the charging pile are monitored respectively to obtain the corresponding current noise information and temperature information. The process of obtaining the temperature of the charging pile may include: detecting the temperature of the charging pile through a temperature detection device corresponding to the charging pile to obtain temperature information according to the corresponding detection result. The temperature detection device corresponding to the charging pile may be a temperature sensor arranged inside the charging pile, and the number of temperature sensors may be one or more. When the number of temperature sensors is more than one, data processing may be performed based on the detection data of multiple temperature sensors to obtain the required temperature information. For example, obtaining the maximum value or average value of the detection data of multiple temperature sensors. The specific process may be designed according to the software design requirements of the scenario. Among them, the position of the temperature sensor may also be set as needed. The process of obtaining the noise of the charging pile may include: detecting the noise of the charging pile through a noise detection device corresponding to the charging pile to obtain noise information according to the corresponding detection result. Among them, the noise detection device corresponding to the charging pile may be a noise sensor arranged corresponding to the charging pile, and the number of noise sensors may be one or more. When the number of noise sensors is more than one, data processing may be performed based on the detection data of multiple noise sensors to obtain the required noise information. For example, obtaining the maximum value or average value of the detection data of multiple noise sensors. The specific process may be designed according to the software design requirements of the scenario. Among them, the position of the noise sensor may also be set as needed. In a specific embodiment, the noise sensor may be arranged at the air inlet of the charging pile to detect the noise at the air inlet of the charging pile; it may also be arranged at the air outlet of the charging pile to detect the noise at the air outlet of the charging pile; noise sensors may also be arranged at the air inlet and air outlet at the same time to obtain the noise at the air inlet and air outlet simultaneously. In an embodiment, a vibration sensor may also be arranged in the charging pile to detect the vibration frequency of the charging pile, so as to obtain more accurate noise information based on the vibration frequency and the detection data of the noise sensor.

[0036] Based on step S3, after obtaining the corresponding noise information and temperature information during the current operation of the charging pile, the noise information can be compared with the noise threshold, and the temperature information can be compared with the temperature threshold respectively, so as to adjust the working mode of the charging pile according to the comparison results. The ultimate goal is to make the noise information and temperature information of the charging pile meet the requirements of the noise threshold and temperature threshold of the charging pile, so as to ensure the use safety and performance during the use of the charging pile, reduce the impact on the surrounding residents, and avoid causing unnecessary nuisance to the residents.

[0037] In one embodiment, in step S1, generating a noise threshold and a temperature threshold corresponding to the charging pile; including: obtaining the application scenario of the charging pile, so as to generate a noise threshold and / or a temperature threshold corresponding to the charging pile according to the application scenario of the charging pile. Specifically, considering that different application scenarios may have different requirements for the noise in the environment, the noise threshold corresponding to the application scenario can be obtained based on the application scenario of the charging pile. For example, when the application environment of the charging pile is a factory area or a highway service area, since there is relatively high noise in the factory environment and highway service area itself, if the set noise threshold of the charging pile is too low, the charging pile may not be in a proper state in order to meet this noise threshold. Therefore, a relatively high noise threshold needs to be set. When the application environment of the charging pile is in a library or a residential community, considering the requirements for noise in the library and residential community, a relatively low threshold needs to be set to avoid disturbing residents due to excessive noise. Therefore, when setting the noise threshold of the charging pile, the corresponding noise threshold needs to be set according to the specific environment. The temperature threshold of the charging pile can also be set based on the application environment. For example, for some application scenarios with large temperature fluctuations, a relatively small temperature threshold can be set to avoid damage to the charging pile caused by sudden overheating during the temperature fluctuation process. It can be understood that the temperature threshold of most charging piles can be set based on the requirements of the internal working circuit of the charging pile and does not need to be adjusted according to the application scenario.

[0038] In one embodiment, in step S1, generating a noise threshold and a temperature threshold corresponding to the charging pile; including: dividing a preset time period to obtain several time segments, and generating a noise threshold and / or a temperature threshold corresponding to the charging pile for each time segment. Specifically, considering that different time segments may also have different requirements for the noise in the environment, the corresponding noise threshold can be set based on the usage time of the charging pile. For example, when the charging pile is used during the day, since the ambient noise itself is relatively high, a relatively high noise threshold can be set. When the charging pile is used at night, in order to meet the requirements of users for noise at night, a relatively low threshold needs to be set to avoid disturbing residents due to excessive noise. Therefore, when setting the noise threshold of the charging pile, the corresponding noise threshold needs to be set according to the specific time segment. In a specific embodiment, the application scenario and the usage time segment can be considered simultaneously for setting the noise threshold. For example, in some scenarios, the noise requirement is low during the day and high at night, then a relatively high noise threshold needs to be set for the daytime time segment and a relatively low noise threshold needs to be set for the nighttime time segment. In some scenarios, the noise requirement is high during the day and low at night, then a relatively low noise threshold can be set for the daytime time segment and a relatively high noise threshold can be set for the nighttime time segment.

[0039] Similarly, the temperature threshold of the charging pile can also be set based on time periods. For example, in some scenarios, the temperature requirement is lower during the day and higher at night. In such cases, a higher temperature threshold needs to be set for the daytime period, and a lower temperature threshold for the nighttime period. In some other scenarios, the temperature requirement is higher during the day and lower at night. Then, a lower temperature threshold can be set for the daytime period, and a higher temperature threshold for the nighttime period. It can be understood that the temperature threshold of most charging piles can be set based on the requirements of the internal working circuit of the charging pile and does not need to be adjusted according to the working time period.

[0040] Optionally, the preset time period is a day. The preset time period is divided to obtain several time periods, including: dividing a day into 24 time periods in hours, and each time period corresponds to one hour. When dividing the time periods according to the preset time period, the day can be used as the preset time period and divided in hours to obtain 24 time periods corresponding to a day. Set the noise threshold corresponding to each hour. For example, store 24 noise thresholds (N1, N2,..., N24), corresponding to the 24 hours of a day respectively. In another embodiment, the preset time period can also be a week. For example, set different noise thresholds for the seven days within a week. It can also be a month or a year, etc., as the preset time period.

[0041] In one embodiment, as Figure 2 shown, in step S3, the working mode of the charging pile is adjusted according to the relationship between the noise information and the noise threshold and the relationship between the temperature information and the temperature threshold, including: S31. When the current noise of the charging pile is not greater than the corresponding noise threshold and the current temperature of the charging pile is greater than the corresponding temperature threshold, increase the working wind speed of the charging pile; S32. When the current noise of the charging pile is greater than the corresponding noise threshold and the current temperature of the charging pile is not greater than the corresponding temperature threshold, lower the working wind speed of the charging pile; S33. When the current noise of the charging pile is greater than the corresponding noise threshold and the current temperature of the charging pile is greater than the corresponding temperature threshold, lower the working wind speed and the output power of the charging pile.

[0042] Specifically, during the adjustment of the working mode of the charging pile, when the current noise of the charging pile is not greater than the noise threshold, if it is confirmed that the current temperature of the charging pile is greater than the corresponding temperature threshold, increase the working wind speed of the charging pile. At this time, since the current noise of the charging pile can meet the noise threshold requirement, the purpose of cooling can be achieved by increasing the wind speed of the charging pile.

[0043] When the current noise of the charging pile is greater than the noise threshold, the current temperature of the charging pile can be confirmed simultaneously. When the current temperature of the charging pile is not greater than the corresponding temperature threshold, the working wind speed of the charging pile can be directly reduced. When the working wind speed of the charging pile is reduced, the noise generated by the internal fan of the charging pile will also be reduced, thereby achieving the purpose of reducing the noise of the charging pile. Because the current temperature of the charging pile can still meet the requirements at this time, even if the wind speed is reduced, the impact on the temperature of the charging pile may not be affected. Through this process, it can be ensured that the noise of the charging pile is normal and does not affect the normal power output of the charging pile.

[0044] In the above process, when the current temperature of the charging pile is confirmed simultaneously and the current temperature of the charging pile is also greater than the corresponding temperature threshold, it is necessary to reduce the working wind speed and the output power of the charging pile simultaneously, so that the current temperature and the current noise of the charging pile can both meet their respective threshold requirements.

[0045] In an embodiment, the corresponding temperature threshold includes a first temperature threshold and a second temperature threshold. When the current noise of the charging pile is greater than the corresponding noise threshold and the current temperature of the charging pile is greater than the corresponding temperature threshold, reducing the working wind speed and the output power of the charging pile includes: when the current temperature of the charging pile is greater than the first temperature threshold and not greater than the second temperature threshold, first reduce the working wind speed of the charging pile, and when the current noise of the charging pile is not greater than the corresponding noise threshold, reduce the output power. That is, when setting the temperature threshold for the charging pile, two different temperature thresholds, namely the first temperature threshold and the second temperature threshold, can be set. When it is determined that the current noise of the charging pile is greater than the corresponding noise threshold, if the current temperature of the charging pile is not too high, that is, the current temperature exceeds the first temperature threshold but does not exceed the second temperature threshold, the noise can be given priority, that is, first reduce the working wind speed of the charging pile to reduce the current noise of the charging pile. When the noise meets the requirements, then adjust the power of the charging pile so that the temperature meets the first temperature threshold.

[0046] Further, when the current noise of the charging pile is greater than the corresponding noise threshold and the current temperature of the charging pile is greater than the corresponding temperature threshold, reducing the working wind speed and the output power of the charging pile further includes: when the current temperature of the charging pile is greater than the second temperature threshold, first reduce the output power, and when the current temperature of the charging pile is lower than the second temperature threshold, reduce the working wind speed. Specifically, when it is determined that the current noise of the charging pile is greater than the corresponding noise threshold, if the current temperature of the charging pile is relatively high, that is, the current temperature exceeds the second temperature threshold, at this time, the temperature of the charging pile should be given priority, and the output power should be reduced first to reduce the current temperature of the charging pile. When the current temperature is lower than the second temperature threshold, then adjust the wind speed of the charging pile so that the noise meets the noise threshold.

[0047] It can be understood that during the process of first adjusting the power and then adjusting the wind speed as described above, when the noise is lower than the noise threshold, the above steps can be repeated to adjust the power so that the current temperature of the charging pile can meet the requirements of the first threshold temperature. That is, during the adjustment of the charging pile working mode, the temperature of the charging pile will be continuously detected to ensure that it is within a safe temperature range and temperature rise range until the user terminates charging or the battery reaches a fully charged state.

[0048] In step S1, a noise threshold and a temperature threshold corresponding to the charging pile are generated, including: obtaining the historical working temperature and historical working noise data of the charging pile in the current environment, and training through a supervised learning model to obtain the noise threshold and temperature threshold corresponding to the current environment. Specifically, the historical working temperature and historical working noise data of the charging pile in the current environment can be obtained, and representative statistical values can be extracted therefrom. For example, calculate the average and standard deviation of the historical noise data, as well as the average and maximum values of the historical temperature data. Then, these statistical values are used as features and input into the supervised learning model for training. Through the training and prediction of the model, the noise threshold and temperature threshold corresponding to the current environment can be obtained.

[0049] Through the above process, the charging pile can adaptively adjust the noise during charging in different environments. At the same time, the noise standard can be flexibly adjusted according to the noise requirements in different time periods so that the working state of the charging pile can better meet the needs.

That is, the steps in the above method are respectively executed by one or more modules.

[0051] In addition, a charging pile of the present invention may further include a memory and a processor; the memory is used to store a computer program; the processor is used to execute the computer program to implement the method of any one of the above.
