[0065] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0066] Figure 1 The following is a flow chart of a charging warning method provided by an exemplary embodiment of the present application. Figure 1 As shown, the charging warning method provided by this application may include:

[0067] S210: Acquire current parameter data.

[0068] Specifically, the current parameter data may represent parameter data that affects the charging operation of the current electrical device. For example, the current parameter data may include the current ambient temperature, the concentration of particulate matter in the current environment, the current light intensity, and the like.

[0069] It should be understood that different types of sensors may be used for detection of different types of current parameter data. For example, the current ambient temperature may be detected by a temperature sensor, and the particle concentration in the current environment may be detected by a smoke sensor.

[0070] S220: Obtaining real parameter data according to current parameter data and historical parameter data.

[0071] Specifically, the historical parameter data may represent the parameter data corresponding to the current parameter data in the past first preset time period. That is, after obtaining the current parameter data, the parameter data corresponding to the current parameter data in the first preset time period may be obtained according to the type of the current parameter data. For example, after obtaining the current ambient temperature, the ambient temperature data in the first preset time period before the current time period may be obtained in the system storage, and then used as part of the historical parameter data.

[0072] It should be understood that when the current parameter data includes the current ambient temperature and the particulate matter concentration in the current environment, the historical parameter data may correspondingly include the ambient temperature data within the past first preset time period and the particulate matter concentration in the environment within the past first preset time period.

[0073] After executing step S220, the background noise in the process of detecting the current parameter data can be separated through the current parameter data and the historical parameter data, so that the accuracy of the real parameter data is significantly improved.

[0074] It should be noted that the first preset time period can be set according to actual conditions, for example, the first preset time period can be selected as one day, one week, one month, etc. The present application does not specifically limit the first preset time period.

[0075] S230: Obtaining a charging safety weighted value according to the actual parameter data.

[0076] Specifically, since the aforementioned current parameter data and historical parameter data may include different types of parameter data that affect the charging operation of the electrical equipment, the actual parameter data obtained based on the current parameter data and historical parameter data may also include different types of parameter data. By weighted calculation of different types of parameter data through intelligent algorithms, a charging safety weighted value can be obtained. Therefore, the charging safety weighted value can characterize the comprehensive impact of different types of parameter data on the charging operation, thereby being able to more accurately reflect the actual situation in the charging shed and reduce the probability of false alarms.

[0077] S240: Outputting a signal indicating normal charging or an alarm signal indicating abnormal charging according to the charging safety weighted value and the safety threshold range.

[0078] Specifically, if the charging safety weighted value is within the safety threshold range, it means that the electrical equipment is in a normal charging state, and the system can output a signal indicating normal charging to continuously monitor the situation in the charging shed. If the charging safety weighted value is outside the safety threshold range, it means that the electrical equipment is in an abnormal charging state, and there is a high probability of a safety accident. At this time, the system can output an alarm message indicating abnormal charging and issue an alarm in time, so that the staff can be informed of the situation in the charging shed in time, take emergency measures, and reduce the probability of safety accidents.

[0079] The charging warning method provided by the present application obtains current parameter data, and then obtains real parameter data based on the current parameter data and historical parameter data, and then obtains a charging safety weighted value based on the real parameter data, and then outputs a signal representing normal charging or an alarm signal representing abnormal charging based on the charging safety weighted value and the safety threshold range. In this way, since the background noise in the process of detecting the current parameter data can be separated through the current parameter data and the historical parameter data, the current parameter data is more accurate, thereby improving the accuracy of the real parameter data. Moreover, since the real parameter data may include different types of parameter data, different types of parameter data are weightedly calculated through an intelligent algorithm, and the obtained charging safety weighted value can represent the comprehensive influence of different types of parameter data on the charging operation, thereby being able to more accurately reflect the real situation in the charging shed and reduce the chance of false alarms.

[0080] Figure 2 This is a flow chart of a charging warning method provided by another exemplary embodiment of the present application. Figure 2 As shown, step S210 may include:

[0081] S211: Acquire current parameter data in different time periods.

[0082] Specifically, the current parameter data in different time periods can be understood as the parameter data that is detected in different time periods and affects the charging operation of the electrical equipment. The current parameter data in different time periods may be different. For example, the ambient temperature in the afternoon and the ambient temperature at night are quite different, so it is not suitable to unify the two in the same time period. Therefore, generally, 7 pm can be used as the dividing point to detect the ambient temperature in different time periods and then store them by category.

[0083] Correspondingly, step S220 may include:

[0084] S221: Obtaining real parameter data in different time periods according to current parameter data in different time periods and corresponding historical parameter data.

[0085] It should be understood that the historical parameter data corresponding to the current parameter data will be different depending on the selected time period. For example, if the current parameter data in the time period from 1:00 p.m. to 7:00 p.m. on May 1st is obtained, then the historical parameter data in the first preset time period from 1:00 p.m. to 7:00 p.m. every day before May 1st can be obtained based on the obtained current parameter data. As mentioned above, the first preset time period before May 1st can be selected from one day before May 1st, one week before May 1st, one month before May 1st, etc. In this way, for the current parameter data in different time periods, the historical parameter data in the corresponding time period can be referred to, so as to separate the background noise in the process of detecting the current parameter data in the corresponding time period, so that the accuracy of the real parameter data obtained in different time periods is correspondingly improved.

[0086] Correspondingly, step S230 may include:

[0087] S231: Obtain charging safety weighted values ​​in different time periods according to actual parameter data in different time periods.

[0088] Specifically, different weights can be selected for the current parameter data in different time periods to obtain charging safety weighted values ​​in different time periods. Applying different safety weighted values ​​for different time periods can more accurately reflect the comprehensive impact of different types of parameter data on charging operations in different time periods, thereby more accurately reflecting the real situation in the charging shed and reducing the probability of false alarms.

[0089] Correspondingly, step S240 may include:

[0090] S241: Outputting a signal indicating normal charging or an alarm signal indicating abnormal charging according to the charging safety weighted values ​​in different time periods and the safety threshold ranges in different time periods.

[0091] Specifically, the safety threshold ranges are different for different selected time periods. For example, the safety threshold range for the afternoon time period may be greater than the safety threshold range for the night time period.

[0092] Figure 3 This is a flow chart of a charging warning method provided by another exemplary embodiment of the present application. Figure 3 As shown, step S210 may further include:

[0093] S212: Obtain current environmental parameter data.

[0094] S213: Obtain charging parameter data of the current charging pile.

[0095] S214: Obtain battery parameter data of the current power-consuming device.

[0096] Specifically, the current parameter data may include current environmental parameter data, current charging pile charging parameter data, and current power-consuming device battery parameter data. The current environmental parameter data may characterize the relevant parameter data that affects the charging operation of the current power-consuming device in the external environment. The current charging pile charging parameter data may characterize the relevant parameter data that affects the charging operation of the current power-consuming device in the charging pile. The current power-consuming device battery parameter data may characterize the relevant parameter data that affects the charging operation of the power-consuming device's battery itself.

[0097] It should be understood that by obtaining the current environmental parameter data, the current charging pile charging parameter data and the current power-consuming equipment battery parameter data, the impact of different types of parameter data on the charging operation can be comprehensively considered, thereby facilitating a more accurate reflection of the specific situation in the charging shed and reducing the chance of false alarms.

[0098] Correspondingly, step S220 may also include:

[0099] S222: According to the current environmental parameter data, the current charging pile charging parameter data, the current battery parameter data of the electric device and the historical parameter data, the real environmental parameter data, the real charging pile charging parameter data and the real battery parameter data of the electric device are obtained.

[0100] Specifically, the real parameter data may include real environment parameter data, real charging pile charging parameter data, and real power equipment battery parameter data. In the actual calculation process, according to the acquired current environment parameter data, current charging pile charging parameter data, and current power equipment battery parameter data, data of the same type can be selected from the historical parameter data, and then background noise can be separated from the current environment parameter data, current charging pile charging parameter data, and current power equipment battery parameter data, so that the accuracy of the real environment parameter data, the real charging pile charging parameter data, and the real power equipment battery parameter data is significantly improved.

[0101] Correspondingly, step S230 may also include:

[0102] S232: Obtain a charging safety weighted value based on the real environment parameter data, the real charging pile charging parameter data, and the real power-consuming device battery parameter data.

[0103] It should be understood that the charging safety weighted value calculated through real environmental parameter data, real charging pile charging parameter data and real electrical equipment battery parameter data comprehensively considers multiple factors that affect the charging operation, and can more accurately reflect the actual situation in the charging shed and reduce the probability of false alarms.

[0104] Figure 4 This is a flow chart of a charging warning method provided by another exemplary embodiment of the present application. Figure 4 As shown, step S212 may include:

[0105] S2121: Obtain the current ambient temperature value and the current particle concentration, and use the current ambient temperature value and the current particle concentration as current ambient parameter data.

[0106] It should be understood that the ambient temperature value and particle concentration have a great impact on safety accidents such as fire and explosion. Therefore, the current ambient temperature and the current particle concentration can be regarded as the main factors affecting the charging operation in the environment. In other words, the current ambient temperature value and the current particle concentration can be regarded as the aforementioned current environmental parameter data.

[0107] Figure 5 This is a flow chart of a charging warning method provided by another exemplary embodiment of the present application. Figure 5 As shown, step S213 may include:

[0108] S2131: Obtain the current charging voltage, current charging current and current temperature of the power bus of the charging pile, and use the current charging voltage, current charging current and current temperature of the power bus as the current charging parameter data of the charging pile.

[0109] Specifically, in the charging parameter data, the current charging voltage, the current charging current and the current temperature of the power bus can be used as the main reference indicators for whether there is a risk in the charging pile. Therefore, the current charging voltage, the current charging current and the current temperature of the power bus can be used as the current charging parameter data of the charging pile as a basis for judging whether there is a risk in the charging operation process.

[0110] It should be understood that the current charging voltage of the charging pile can be detected by a voltmeter, the current charging current of the charging pile can be detected by an ammeter, and the current temperature of the power bus can be detected by a temperature sensor arranged on the power bus.

[0111] Figure 6 A schematic diagram of a process for obtaining battery parameter data of a current power-consuming device provided by an exemplary embodiment of the present application. Figure 6 As shown, step S214 may include:

[0112] S2141: Obtain the identification number of the current power-consuming device.

[0113] Specifically, the identification number of the current power-consuming device may also be referred to as the ID number of the current power-consuming device. The type of battery of the current power-consuming device may be confirmed based on the identification number of the current power-consuming device, thereby facilitating subsequent determination of charging parameters associated with the type of battery.

[0114] S2142: Obtain a safe charging curve of the current power-consuming device according to the identification number, and use the safe charging curve as battery parameter data of the current power-consuming device.

[0115] Specifically, different types of electrical equipment have different identification numbers. The safe charging curves of the batteries of different types of electrical equipment can be stored in the system. After confirming the identification number of the current electrical equipment, the safe charging curve of the current electrical equipment can be obtained. The safe charging curve can be understood as the changes in various charging parameters when charging this type of battery, which can reflect whether the charging operation is in a normal state. Therefore, the safe charging curve can be used as the battery parameter data of the current electrical equipment, which is used as a basis for judging whether there are risks in the charging operation process.

[0116] Figure 7 This is a flow chart of a charging warning method provided by another exemplary embodiment of the present application. Figure 7 As shown, before step S240, the charging warning method may further include:

[0117] S250: Obtain the current time period corresponding to the current parameter data.

[0118] Specifically, in the process of acquiring the current parameter data, a timing device may be turned on accordingly. After data collection is completed, the current time period corresponding to the current parameter data may be obtained according to the data recorded by the timing device.

[0119] S260: Obtain a safety threshold range within the current time period according to the current time period and the historical threshold range.

[0120] Correspondingly, step S240 may include:

[0121] S242: Outputting a signal indicating normal charging or an alarm signal indicating abnormal charging according to the charging safety weighted value and the safety threshold range in the current time period.

[0122] For example, if the current time period is from 1:00 p.m. to 7:00 p.m. on May 1st, then the safety threshold range from 1:00 p.m. to 7:00 p.m. in the second preset time period before May 1st can be referred to to obtain the safety threshold range in the current time period. Since the safety threshold range in the current time period refers to the historical threshold range, this is more accurate than directly setting it based on human experience and can more accurately avoid safety accidents.

[0123] It should be noted that the second preset time period can be set according to actual conditions, for example, the second preset time period can be selected as one day, one week, one month, etc. The present application does not specifically limit the second preset time period.

[0124] Figure 8 This is a flow chart of a charging warning method provided by another exemplary embodiment of the present application. Figure 8 As shown, when executing step S210, step S220 and step S230, step S240 may further include:

[0125] S243: If the charging safety weighted value is within the safety threshold range, output a signal indicating that charging is normal.

[0126] S244: If the charging safety weighted value is outside the safety threshold range, an alarm signal indicating abnormal charging is output, and the charging pile is controlled to stop charging.

[0127] It should be understood that if the charging safety weighted value is within the safety threshold range, it means that the electrical equipment is in a normal charging state, and the system can output a signal indicating normal charging to continuously monitor the situation in the charging shed. If the charging safety weighted value is outside the safety threshold range, it can indicate that the electrical equipment is in an abnormal charging state, and there is a greater probability of a safety accident. At this time, the system can output alarm information indicating abnormal charging and issue an alarm in time, so that the staff can be informed of the situation in the charging shed in a timely manner, take emergency measures, and reduce the probability of safety accidents.

[0129] The charging warning device provided in the present application obtains current parameter data, and then obtains real parameter data based on the current parameter data and historical parameter data, and then obtains a charging safety weighted value based on the real parameter data, and then outputs a signal representing normal charging or an alarm signal representing abnormal charging based on the charging safety weighted value and the safety threshold range. In this way, since some background noise in the process of detecting the current parameter data can be separated through the current parameter data and the historical parameter data, the current parameter data is more accurate, thereby improving the accuracy of the real parameter data. Moreover, since the real parameter data may include different types of parameter data, different types of parameter data are weightedly calculated through an intelligent algorithm, and the obtained charging safety weighted value can represent the comprehensive influence of different types of parameter data on the charging operation, thereby being able to more accurately reflect the real situation in the charging shed and reduce the chance of false alarms.

[0139] In one embodiment, the plurality of sensors 630 may include a temperature sensor, a smoke sensor, a voltage sensor, a current sensor, etc.

[0140] The charging shed provided in the present application obtains current parameter data, and then obtains real parameter data based on the current parameter data and historical parameter data, and then obtains a charging safety weighted value based on the real parameter data, and then outputs a signal representing normal charging or an alarm signal representing abnormal charging based on the charging safety weighted value and the safety threshold range. In this way, since some background noise in the process of detecting the current parameter data can be separated out through the current parameter data and the historical parameter data, the current parameter data is more accurate, thereby improving the accuracy of the real parameter data. Moreover, since the real parameter data may include different types of parameter data, the different types of parameter data are weightedly calculated through an intelligent algorithm, and the obtained charging safety weighted value can represent the comprehensive influence of different types of parameter data on the charging operation, thereby being able to more accurately reflect the real situation in the charging shed and reduce the chance of false alarms.
