[0017] Figure 1 It is a schematic flowchart of steps S100 - S500 in an automatic power-off protection method for an intelligent charging station proposed by the present invention; Figure 2 It is a structural block diagram of an automatic power-off protection system for an intelligent charging station proposed by the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The following preferred embodiments are only examples, and those skilled in the art can think of other obvious variations.

[0019] Refer to Figure 1As shown in the figure, an automatic power-off protection method for an intelligent charging station includes: S100. Obtain the type of the intelligent charging station to be protected, and based on the intelligent control terminal, perform data retrieval and analysis with the type of the intelligent charging station to be protected as the feature to determine the maintenance information of intelligent charging stations of the same type; S200. Based on the intelligent control terminal, perform anomaly analysis on the maintenance information of intelligent charging stations of the same type to determine the high-frequency accident locations; S300. Based on the intelligent control terminal, perform time analysis on the maintenance information of intelligent charging stations of the same type with the high-frequency accident locations as the features to determine the abnormal data change rate and the normal data change rate; S400. Based on the intelligent control terminal, analyze and process the high-frequency accident locations to determine the installation locations of the monitoring devices; S500. Based on the intelligent control terminal, control the monitoring devices to perform data monitoring and analysis on the intelligent charging station to be protected, and select whether to perform power-off protection on the intelligent charging station to be protected; Those skilled in the art can understand that when an intelligent charging station charges a device to be charged, situations such as overheating, overvoltage, and overcurrent may occur. Some faults rarely occur, while some faults often occur. If all devices inside the intelligent charging station are monitored, it will increase the operating cost of the intelligent charging station and, at the same time, reduce the profit of the intelligent charging station. Therefore, by analyzing the abnormal data in the maintenance information of intelligent charging stations of the same type, the high-frequency accident locations are determined. Then, by calculating the historical operation data of the intelligent charging station based on the occurrence time of the high-frequency accident locations, the abnormal data before maintenance (i.e., the instantaneous abnormal data set) and the normal data after maintenance (i.e., the instantaneous normal data set) are obtained. Then, these data are averaged to obtain the abnormal data change rate and the normal data change rate. Finally, by analyzing the high-frequency accident locations and the internal structure diagram of the intelligent charging station to be protected, the installation locations of the monitoring devices are determined. The monitoring devices are installed at the installation locations of the monitoring devices, and then the intelligent charging station to be protected is monitored through the monitoring devices to obtain the instantaneous operation data of the high-frequency accident locations, and it is compared and judged with the abnormal data change rate and the normal data change rate to select whether to perform power-off protection on the intelligent charging station to be protected. The above method reduces the number of monitoring devices used, reduces the operating cost of the intelligent charging station, and at the same time, increases the profit of the intelligent charging station.

[0020] Embodiment 1 Obtaining the type of the intelligent charging station to be protected, and based on the intelligent control terminal, performing data retrieval and analysis with the type of the intelligent charging station to be protected as the feature to determine the maintenance information of intelligent charging stations of the same type specifically includes the following steps: S101. Obtain the electrical layout diagram of the intelligent charging station to be protected; S102. Based on the intelligent control terminal, perform a location analysis on the electrical layout diagram of the intelligent charging station to be protected, and determine the installation location of the intelligent charging station to be protected; S103. Based on the intelligent control terminal, perform information extraction and processing on the database system using the installation location of the intelligent charging station to be protected as a feature, and obtain the type of the intelligent charging station to be protected; S104. Based on the intelligent control terminal, perform data retrieval processing on the database system using the type of the intelligent charging station to be protected as a feature, and obtain the maintenance information of intelligent charging stations of the same type; In this embodiment, there are multiple types of intelligent charging stations. For different types of intelligent charging stations, their fault locations may be different. The installation location of the intelligent charging station is determined according to the electrical layout diagram. In an electrical layout diagram, in addition to the location of the intelligent charging station, there are also the locations of other electrical equipment. Therefore, it is necessary to determine the installation location of the intelligent charging station to be protected according to the electrical layout diagram. After the installation location of the intelligent charging station to be protected is determined, its type is determined according to the installation location of the intelligent charging station to be protected, and then information retrieval is performed on the database system according to its type to obtain the maintenance information of intelligent charging stations of the same type. Because all the fault information of this type of intelligent charging station will exist in the maintenance information of intelligent charging stations of the same type. Then, only by analyzing these fault information can the high-frequency accident locations be determined. Subsequently, only by analyzing the high-frequency accident locations can the installation locations of the monitoring devices be determined.

[0021] Embodiment 2 Based on the intelligent control terminal, perform abnormal analysis on the maintenance information of intelligent charging stations of the same type to determine the high-frequency accident locations, which specifically includes the following steps: S201. Based on the intelligent control terminal, perform data extraction and processing on the maintenance information of intelligent charging stations of the same type, and determine the maintenance locations of the intelligent charging stations; S202. Based on the intelligent control terminal, perform data counting processing on the maintenance information of intelligent charging stations of the same type using the maintenance locations of the intelligent charging stations as features, and obtain the maintenance times of the maintenance locations; S203. Based on the intelligent control terminal, perform analysis and processing on the maintenance times of the maintenance locations, and determine the high-frequency accident locations; In this embodiment, the interior of the intelligent charging station consists of multiple electrical devices. However, some electrical devices are prone to failure, while some are not. If monitoring devices are installed on the accessories of each electrical device, the operating cost of the intelligent charging station will be increased. Therefore, analyze the maintenance information of intelligent charging stations of the same type, determine the maintenance locations of the intelligent charging stations, then count the maintenance locations in the maintenance information of intelligent charging stations of the same type to obtain the maintenance times of each maintenance location. Finally, judge the maintenance times of the maintenance locations to obtain the high-frequency accident locations.

[0022] Example 3 Based on the intelligent control terminal, analyzing and processing the maintenance times at the maintenance locations to determine the high-frequency accident locations specifically includes the following steps: S2031. Based on the intelligent control terminal, judging and processing the maintenance times at the maintenance locations and the set maintenance times threshold; S2032. If the maintenance times at the maintenance location are greater than or equal to the set maintenance times threshold, set this maintenance location as a high-frequency accident location; S2033. If the maintenance times at the maintenance location are less than the set maintenance times threshold, this maintenance location is an accidental accident location; In this embodiment, some of the electrical equipment inside the intelligent charging station is not easily damaged, and its maintenance times are relatively few. If monitoring equipment is installed to monitor its status, it will increase the operating cost of the intelligent charging station. Therefore, it is necessary to exclude the electrical equipment that is not easily damaged. Therefore, by judging the maintenance times at the maintenance locations, it is excluded.

[0023] Example 4 Based on the intelligent control terminal, analyzing the maintenance information of the same type of intelligent charging stations at all times with the high-frequency accident locations as features to determine the abnormal data change rate and the normal data change rate specifically includes the following steps: S301. Based on the intelligent control terminal, extracting data from the maintenance information of the same type of intelligent charging stations with the high-frequency accident locations as features to obtain the high-frequency accident occurrence time and the high-frequency accident end time; S302. Based on the intelligent control terminal, reading data from the database system with the same type of intelligent charging stations as features to obtain the historical operation data of the same type of intelligent charging stations; S303. Based on the intelligent control terminal, extracting data from the historical operation data of the same type of intelligent charging stations with the high-frequency accident occurrence time and the high-frequency accident end time as features to obtain the instantaneous abnormal data set and the instantaneous normal data set; S304. Based on the intelligent control terminal, calculating the instantaneous abnormal data set and the instantaneous normal data set to obtain the abnormal data change rate and the normal data change rate; In this embodiment, the data before the occurrence time of the high-frequency accident represents the data when the electrical equipment fails. If 1S is taken as the instantaneous reference, then this data is the instantaneous change rate. However, if only the data of one such type of intelligent charging station is taken as the reference, the error rate will be increased. Therefore, the data corresponding to all such high-frequency accidents of this type are averaged to obtain an average value, that is, the abnormal data change rate. The average data obtained from a large number of data can more accurately reflect the data when the intelligent charging station fails. Similarly, when the data corresponding to the time after the high-frequency accident ends is the normal data, in order to obtain more accurate normal data, the same calculation method as the abnormal data change rate is adopted to obtain the normal data change rate.

[0024] Embodiment 5 Based on the intelligent control terminal, calculating and processing the instantaneous abnormal data set and the instantaneous normal data set to obtain the abnormal data change rate and the normal data change rate specifically includes the following steps: S3041. Based on the intelligent control terminal, sum the data in the instantaneous abnormal data set and the instantaneous normal data set respectively to obtain the sum of the instantaneous abnormal data and the sum of the instantaneous normal data; S3042. Based on the intelligent control terminal, count the internal data of the instantaneous abnormal data set or the instantaneous normal data set to obtain the total number of data. The number of internal data of the instantaneous abnormal data set and the instantaneous normal data set is the same; S3043. Based on the intelligent control terminal, average the sum of the instantaneous abnormal data, the total number of data, the sum of the instantaneous normal data, and the total number of data respectively to obtain the abnormal data change rate and the normal data change rate; In this embodiment, the data inside the instantaneous abnormal data set is the data when an accident occurs at the location of the high-frequency accident, and this data is extracted from the historical operation data of the same type of intelligent charging station. This data is of the same type of fault, and the number of internal data in the instantaneous normal data set is equal to the number of internal data in the instantaneous abnormal data set.

[0025] Embodiment 6 Based on the intelligent control terminal, analyze and process the location of the high-frequency accident to determine the installation location of the monitoring device, specifically including the following steps: S401. Based on the intelligent control terminal, read the data from the database system with the type of the intelligent charging station to be protected as the feature to obtain the factory description of the intelligent charging station to be protected; S402. Based on the intelligent control terminal, extract the information from the factory description of the intelligent charging station to be protected to obtain the internal structure diagram of the intelligent charging station to be protected; S403. Based on the intelligent control terminal, perform location analysis on the internal structure diagram of the intelligent charging station to be protected with the high-frequency accident location as the feature, and determine the installation location of the monitoring device. In this embodiment, the high-frequency accident location only represents the location where faults are likely to occur in this type of intelligent charging station. However, the installation locations of the electrical equipment inside the intelligent charging station are not clear. To determine the installation location of the monitoring device, it is necessary to perform location analysis on the internal structure diagram of the intelligent charging station to be protected before the installation location of the monitoring device can be determined.

[0026] Embodiment 7 Based on the intelligent control terminal, control the monitoring device to perform data monitoring and analysis on the intelligent charging station to be protected, and select whether to perform power-off protection on the intelligent charging station to be protected. The specific steps are as follows: S501. Based on the intelligent control terminal, install the monitoring device inside the intelligent charging station to be protected according to the installation location of the monitoring device. S502. Based on the monitoring device, collect data from the intelligent charging station to be protected and obtain the instantaneous operation data of the high-frequency accident location. S503. Based on the intelligent control terminal, analyze and process the instantaneous operation data of the high-frequency accident location, and select whether to perform power-off protection on the intelligent charging station to be protected. In this embodiment, after the monitoring device is installed near the electrical equipment prone to failure, the monitoring device collects data from these electrical equipment prone to failure, and then compares it with the abnormal data change rate and the normal data change rate to select whether to perform power-off protection on the intelligent charging station to be protected.

[0027] Embodiment 8 Based on the intelligent control terminal, analyze and process the instantaneous operation data of the high-frequency accident location, and select whether to perform power-off protection on the intelligent charging station to be protected. The specific steps are as follows: S5031. Based on the intelligent control terminal, judge and process the instantaneous operation data of the high-frequency accident location, the abnormal data change rate, and the normal data change rate. S5032. If the instantaneous operation data of the high-frequency accident location is greater than or equal to the abnormal data change rate, perform power-off protection on the intelligent charging station to be protected, and based on the intelligent control terminal, send device maintenance information to the electronic device of the maintenance personnel. S5033. If the instantaneous operation data of the high-frequency accident location is greater than or equal to the normal data change rate and less than the abnormal data change rate, perform power-off protection on the intelligent charging station to be protected. S5034. If the instantaneous operation data of the high-frequency accident location is equal to the normal data change rate, the intelligent charging station to be protected operates normally. S5035. If the instantaneous operation data at the high-frequency accident location is less than the normal data change rate, power-off protection is performed on the intelligent charging station to be protected, and based on the intelligent control terminal, equipment maintenance information is sent to the electronic devices of the maintenance personnel. In this embodiment, when the operation data at the high-frequency accident location is greater than or equal to the abnormal data change rate, or the instantaneous operation data at the high-frequency accident location is less than the normal data change rate, it indicates that there is a fault in the electrical equipment at this location. Since the interior of the intelligent charging station consists of multiple electrical equipment, in order to avoid faults in other electrical equipment, power-off protection needs to be performed on the intelligent charging station. Therefore, the monitoring equipment monitors the electrical equipment in the intelligent charging station that is prone to faults. When the real-time operation data of those electrical equipment prone to faults becomes abnormal, power-off protection is immediately performed on the intelligent charging station.
