[0022] If so, the power supply to the household is stopped, and a corresponding early warning strategy is selected according to the current moment to issue an early warning.

[0023] Optionally, after the step of stopping power supply to the household and selecting a corresponding early warning strategy for early warning according to the current moment, the method further includes:

[0029] Generate an early warning strategy based on the adjusted escape route and issue an early warning.

[0030] Optionally, before the step of adjusting the initial escape route according to the fire spread trend information and the smoke spread trend information, the method further includes:

[0031] Obtaining the household structure of the household and constructing a three-dimensional space model based on the household structure;

[0050] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0053] Those skilled in the art will understand that Figure 1 The structure shown in does not constitute a limitation on the insulation detection device for the energy storage system, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0054] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and an energy storage system insulation detection program.

[0055] exist Figure 1 In the energy storage system insulation detection device shown, the network interface 1004 is primarily used for data communication with a network server; the user interface 1003 is primarily used for data interaction with a user; the processor 1001 and the memory 1005 in the energy storage system insulation detection device of the present invention can be provided in the energy storage system insulation detection device. The energy storage system insulation detection device calls the energy storage system insulation detection program stored in the memory 1005 via the processor 1001 and executes the energy storage system insulation detection method provided in an embodiment of the present invention.

[0056] The embodiment of the present invention provides an energy storage system insulation detection method, referring to Figure 2 , Figure 2 Schematic diagram of the flow of the first embodiment of the energy storage system insulation detection method of the present invention.

[0057] In this embodiment, the energy storage system insulation detection method includes the following steps:

[0058] Step S10: obtaining the current output voltage of the high-voltage bus of the energy storage system and obtaining a preset voltage threshold.

[0059] It should be noted that the method of this embodiment can be applied in scenarios where insulation testing is performed on energy storage systems, or in scenarios where insulation testing is performed on other systems. The execution subject of this embodiment can be an energy storage system insulation testing device with data processing, network communication, and program execution functions, such as an insulation tester, or other devices capable of performing the same or similar functions. This embodiment and the following embodiments will be specifically described using the above-mentioned energy storage system insulation testing device (hereinafter referred to as the device).

[0060] It is understandable that the above-mentioned energy storage system can be used to store energy for photovoltaic power generation, or to store energy for other power generation methods. The output end of the above-mentioned energy storage system can be connected to the inverter, and the electric energy can be transmitted to the transformer through the high-voltage bus to supply power to the corresponding users.

[0061] It should be understood that the above-mentioned preset voltage threshold can be a threshold set by the staff based on the output voltage of the high-voltage bus under the user's power consumption status. The above-mentioned equipment can analyze the daily voltage changes of the user within a year as a cycle, obtain the average voltage, and set the preset voltage threshold based on the above-mentioned average voltage. The above-mentioned preset voltage threshold can be used to determine whether the above-mentioned energy storage system is in the peak power consumption period.

[0062] As another implementation of this embodiment, considering that the preset voltage threshold obtained with a cycle of one year may not be accurate enough, the above-mentioned device can also obtain the above-mentioned preset voltage threshold with a cycle of one quarter or one month. The specific cycle is not limited in this embodiment.

[0063] In a specific implementation, the above-mentioned device can first obtain the current output voltage of the high-voltage bus of the energy storage system output to the user, and obtain the preset voltage threshold obtained by analyzing the daily voltage changes of the user.

[0064] Step S20: determining whether the current output voltage is lower than the preset voltage threshold.

[0065] It should be noted that the energy storage system may be provided with an insulation detection voltage for insulation detection. The initial value of the insulation detection voltage may be a voltage value set by the user under normal power usage. When the current output voltage is lower than the preset voltage threshold, it can be determined that the energy storage system is in a peak power usage period. The current output voltage may be lower than the insulation detection voltage, resulting in a misjudgment. In this case, the device may adjust the insulation detection voltage.

[0066] Furthermore, considering that when a short circuit occurs in the user's load device, the current output voltage will also decrease and may be lower than the preset voltage threshold, but the energy storage system is not short-circuited at this time, in order to accurately judge the change in the current output voltage, before the above step S20, the following steps are further included:

[0067] Step S11: obtaining the power supply area corresponding to the high-voltage bus of the energy storage system, and obtaining the current power voltage in the power supply area;

[0068] Step S12: determining whether the current power voltage and the current output voltage are within a preset range;

[0069] Step S13: If yes, executing the step of determining whether the current output voltage is lower than the preset voltage threshold.

[0070] It is understandable that the high-voltage busbar of the energy storage system can correspond to multiple power supply areas, and the specific number of power supply areas is not limited in this embodiment.

[0071] It should be understood that when a short circuit occurs in one of the above-mentioned power supply areas, the above-mentioned current power voltage will decrease, and the above-mentioned preset range can be set according to the power parameters of the load equipment in the power supply area. For example, if there are a large number of high-power load devices in the power supply area, the current power voltage will decrease more when a short circuit occurs, and the above-mentioned preset range can be set larger. It should be emphasized that the above examples are only for ease of understanding, and the setting of the above-mentioned preset range can also be set according to other parameters.

[0072] In a specific implementation, the above-mentioned device can obtain the power supply area corresponding to the high-voltage bus of the energy storage system, and obtain the current power consumption voltage corresponding to the above-mentioned power supply area; determine whether the current power consumption voltage and the current output voltage are within a preset range. If not, it can be determined that the change in the above-mentioned current output voltage is caused by a short circuit in the above-mentioned power supply area, and the above-mentioned device can prompt the staff to take relevant measures in time. If so, it can be determined that the change in the above-mentioned current output voltage is caused by a short circuit in the above-mentioned power supply area. The above-mentioned device will determine whether the current output voltage is lower than the preset voltage threshold, and then eliminate the interference caused by the short circuit of the load equipment, thereby improving the judgment accuracy.

[0073] Step S30: If yes, obtain a corresponding voltage regulation strategy according to the current output voltage, and adjust the insulation detection voltage based on the voltage regulation strategy.

[0074] It should be noted that the above-mentioned device can classify the current output voltage into levels, and the above-mentioned classification results may include the first level, the second level and the third level. The above-mentioned voltage regulation strategy may include the first voltage regulation strategy, the second voltage regulation strategy and the third voltage regulation strategy. The first level corresponds to the first voltage regulation strategy, the second level corresponds to the second voltage regulation strategy, and the third level corresponds to the third voltage regulation strategy.

[0075] It can be understood that the above-mentioned first level may indicate that the current input voltage is relatively close to the above-mentioned preset voltage threshold, and the above-mentioned first voltage regulation strategy can be added on the basis of proportionally adjusting the insulation detection voltage. The above-mentioned second level may indicate that the current input voltage is relatively far away from the above-mentioned preset voltage threshold, and the above-mentioned second voltage regulation strategy can be adjusted proportionally. The above-mentioned third level may indicate that the current input voltage is very far away from the above-mentioned preset voltage threshold, and the above-mentioned third voltage regulation strategy can be reduced on the basis of proportionally adjusting the insulation detection voltage, thereby increasing the accuracy of the preset voltage threshold.

[0076] For ease of understanding, the following example illustrates that if the current output voltage is 10kV, the preset voltage threshold is 9kV, and the insulation detection voltage is 8kV, the ratio between the insulation detection voltage and the current output voltage is 0.8. When the current output voltage drops to 7.8kV, the device can be determined to be at the first level, and the first voltage regulation strategy can obtain an insulation detection voltage of 6.24kV according to the ratio. However, to improve accuracy, an additional voltage can be added to the above 6.24kV, and the final adjusted insulation detection voltage can be 6.5kV.

[0077] If the current output voltage drops to 7kV, the above device can be determined to be at the second level, and the second voltage regulation strategy can obtain an adjusted insulation detection voltage of 5.6kV according to the proportion;

[0078] If the current output voltage drops to 6.8KV, the above-mentioned device can be judged as the third level, and the third voltage regulation strategy can obtain an insulation detection voltage of 5.44KV according to the proportion. However, in order to improve the accuracy, it can be reduced based on the above 5.44KV, and the final adjusted insulation detection voltage can be 5.2KV.

[0079] It should be emphasized that the above examples are for ease of understanding only and do not limit parameters such as the current output voltage corresponding to each level, the specific ratio, and the specific insulation detection voltage.

[0080] In a specific implementation, when the above-mentioned device determines that the current output voltage is lower than the preset voltage threshold, it classifies the current output voltage into levels, obtains the corresponding voltage regulation strategy based on the level classification result, and finally adjusts the insulation detection voltage based on the voltage regulation strategy.

[0081] Step S40: performing insulation testing on the energy storage system using the adjusted insulation testing voltage.

[0082] Furthermore, considering that the service life of the energy storage system is likely to be reduced when charging and discharging are carried out simultaneously, after the above-mentioned step S40, it also includes: obtaining the current input power and the current output power of the energy storage system; judging whether the current input power and the current output power meet the preset power supply requirements; if so, supplying power to the power supply area according to the current input power.

[0083] It should be noted that the above-mentioned current input power is the charging power provided by the power generation equipment to the energy storage system, and the above-mentioned current output power is the power consumption provided by the energy storage system to the corresponding power supply area.

[0084] It is understandable that the preset power supply requirement may be a requirement that the current input power can support direct output to the power supply area.

[0085] In a specific implementation, the above-mentioned device can obtain the current input power and current output power of the energy storage system. When the current input power meets the conditions for directly supplying power to the power supply area, the power supply route is switched from the original power supply through the energy storage system to direct power supply through the power generation equipment. In this way, the power generated by the power generation equipment does not need to pass through the energy storage system, thereby extending the service life of the energy storage system.

[0086] This embodiment can first obtain the current output voltage of the high-voltage bus of the energy storage system output to the user, and obtain a preset voltage threshold obtained by analyzing the daily voltage changes of the user; obtain the power supply area corresponding to the high-voltage bus of the energy storage system, and obtain the current power consumption voltage corresponding to the above power supply area; determine whether the current power consumption voltage and the current output voltage are within the preset range. If not, it can be determined that the cause of the change in the above current output voltage is caused by a short circuit in the above power supply area, and the above device can prompt the staff to take relevant measures in time. If so, it can be determined that the cause of the change in the above current output voltage is caused by a peak period of electricity consumption. The above device will determine whether the current output voltage is lower than the preset voltage threshold, and then eliminate the interference caused by the short circuit of the load equipment, thereby improving the judgment accuracy; when determining the current output voltage When the voltage is lower than the preset voltage threshold, the current output voltage is graded, and the corresponding voltage regulation strategy is obtained according to the grade classification result. Finally, the insulation detection voltage is adjusted based on the voltage regulation strategy. The energy storage system is insulation tested by the adjusted insulation detection voltage, and then the insulation detection voltage can be adjusted according to the corresponding voltage regulation strategy when the peak power consumption period is determined, thereby improving the accuracy of the detection. At the same time, this embodiment can also obtain the current input power and current output power of the energy storage system, and when the current input power meets the conditions for directly supplying power to the power supply area, the power supply route is switched from the original power supply through the energy storage system to direct power supply through the power generation equipment, so that the power generated by the power generation equipment does not need to pass through the energy storage system, thereby extending the service life of the energy storage system.

[0087] refer to Figure 3 , Figure 3 2 is a flow chart of a second embodiment of the energy storage system insulation detection method of the present invention.

[0088] Considering that when the energy storage system is supplying power, the user's load equipment may be prone to short circuit, and in order to improve safety, based on the above embodiment, as Figure 3 As shown, in this embodiment, after the above step S40, the following steps are further included:

[0089] Step S50: obtaining the real-time current value of the households in the power supply area, and drawing a current curve according to the real-time current value.

[0090] It should be noted that the above-mentioned real-time current value is the real-time electricity consumption value of the household, which can be obtained according to the electricity meter corresponding to the household.

[0091] Step S60: obtaining a real-time slope according to the current curve, and determining whether the real-time slope exceeds a preset slope threshold.

[0092] It is understandable that when a short circuit occurs in the load equipment in the household, the current in the load equipment will increase dramatically, and the above-mentioned real-time slope will also increase dramatically. The above-mentioned preset slope threshold can be set according to actual conditions, and this embodiment does not limit this.

[0093] Step S70: If yes, stop supplying power to the household and issue an early warning according to a corresponding early warning strategy at the current moment.

[0094] It should be understood that, considering that the residents are in different states at different times, the warning strategies that can be adopted may also be different. For example, when the residents are sleeping at the current moment, the above-mentioned warning strategy can be to broadcast a warning sound to remind the user, and at the same time send a warning signal to the terminal device of the emergency contact set by the residents. If the residents are not at home at the current moment, the above-mentioned warning strategy can be to send a warning message to the resident's terminal device. The above examples are only for ease of understanding and do not limit the actual warning strategy.

[0095] It should be emphasized that the resident status corresponding to the current moment can be set according to the resident's daily routine. For example, if the resident's sleeping time is from 10 pm to 7 am the next day, the corresponding resident status can be set to sleeping.

[0096] In a specific implementation, the above-mentioned device can obtain the real-time current value of the residents in the power supply area, draw a current curve based on the real-time current value, obtain the real-time slope based on the current curve, and judge whether the real-time slope exceeds the preset slope threshold. If it exceeds, it is determined that a short circuit has occurred in the load equipment in the above-mentioned household, and then the power supply to the residents can be stopped. The corresponding early warning strategy is adopted according to the current moment to prompt the user to check in time, thereby improving safety.

[0097] Furthermore, considering that a short circuit in the load equipment is more likely to cause a fire, in order to promptly detect whether a fire has occurred, after the above step S70, it also includes: obtaining the alarm threshold of the fire protection system installed in the household, and determining whether the alarm threshold exceeds the preset alarm threshold; if so, adjusting the alarm threshold.

[0098] It should be noted that the fire protection system may include a smoke alarm system or other systems for fire detection. In this embodiment, the smoke alarm system is used for illustration.

[0099] It is understandable that the above-mentioned alarm threshold may be the smoke concentration threshold of the above-mentioned smoke alarm system, and the above-mentioned preset alarm threshold may be the threshold used to distinguish between a normal state and a sensitive state, and may be set according to actual conditions.

[0100] In a specific implementation, when a short circuit occurs in a household, the above-mentioned equipment can obtain the alarm threshold of the fire protection system in the household. Since a short circuit can easily cause a fire, the alarm of the above-mentioned fire protection system can be adjusted to a more sensitive state. When a certain amount of smoke appears, the above-mentioned fire protection system can be monitored through the adjusted alarm threshold and the fire can be detected in time.

[0101] This embodiment obtains the real-time current value of the residents in the power supply area, draws a current curve based on the real-time current value, obtains the real-time slope based on the current curve, and determines whether the real-time slope exceeds a preset slope threshold. If it exceeds, it is determined that a short circuit occurs in the load equipment in the above-mentioned household, and the power supply to the resident can be stopped. The corresponding early warning strategy is adopted according to the current moment to prompt the user to check in time, thereby improving safety. At the same time, when a short circuit occurs in the resident, the above-mentioned device can obtain the alarm threshold of the fire protection system in the resident. Since a short circuit can easily cause a fire, the above-mentioned device can determine whether the alarm threshold exceeds the preset alarm threshold. If so, it means that the current fire protection system is not in a sensitive state, and the alarm of the above-mentioned fire protection system can be adjusted to a more sensitive state. When a certain amount of smoke appears, the above-mentioned fire protection system can be monitored through the adjusted alarm threshold, and the fire can be detected in time.

[0102] refer to Figure 4 , Figure 4 2 is a flow chart of a third embodiment of the energy storage system insulation detection method of the present invention.

[0103] Considering that when a fire occurs, it is easy to cause the residents to panic, which is not conducive to determining the escape route, and in order to further increase safety, based on the above embodiments, as Figure 4 As shown, in this embodiment, the step of selecting the corresponding warning strategy for warning according to the current moment includes:

[0104] Step S71: Determine the location of the resident at the current moment, and obtain an initial escape route based on the location.

[0105] It should be noted that the above-mentioned equipment can determine whether a fire occurs through the above-mentioned fire protection system. If the fire protection system is triggered, it can be determined that a fire occurs. The above-mentioned equipment can also determine whether a fire occurs through an infrared thermal imager in the resident's home, or other methods of determining whether a fire occurs. This embodiment does not limit the comparison.

[0106] It is understandable that after the above-mentioned equipment determines that a fire has occurred and the resident is at home at this time, the above-mentioned equipment can determine the resident's location based on the current time. The above-mentioned location may include: bedroom, living room, kitchen, etc. This embodiment is not limited. For example, if the current time is 11 o'clock in the morning, the resident may be in the kitchen.

[0107] It should be understood that in order to accurately determine the location of the residents, the above-mentioned location can also be obtained through the images captured by the cameras in the residents' homes. However, considering that the fire may make it impossible to power the camera, or the smoke generated by the fire may block the camera's shooting, as another implementation method of this embodiment, the above-mentioned device can also locate the resident's mobile phone, and determine the resident's location based on the mobile phone positioning. It also includes the case that the resident does not carry a mobile phone. As another implementation method of this embodiment, the above-mentioned device can also locate the bracelet worn by the resident, and determine the resident's location based on the position of the bracelet.

[0108] It should be noted that it is also taken into consideration that the residents may not be wearing bracelets, and the above-mentioned equipment can also collect the sounds made by the residents and determine the residents' location based on the sounds.

[0109] It should be emphasized that the above-mentioned initial escape route can be the nearest escape route determined based on the resident's location and escape exit. The staff can pre-set the initial escape routes corresponding to different locations and save the above-mentioned initial escape routes into the above-mentioned device.

[0110] In a specific implementation, the above-mentioned device can determine the location of the residents according to the current moment after a fire occurs, and obtain the corresponding initial escape route based on the above-mentioned location.

[0111] Step S72: Obtain fire spread trend information and smoke spread trend information, and adjust the initial escape route according to the fire spread trend information and the smoke spread trend information.

[0112] It is understandable that the fire spread trend information and smoke spread trend information can be obtained through temperature sensors and smoke sensors in the fire protection system, and can also be obtained through other methods, which are not limited in this embodiment.

[0113] It should be understood that since the initial escape route only considers the shortest distance between the location and the escape exit, when there is a fire or thick smoke in the initial escape route, it is not conducive to the escape of the residents. Therefore, the above-mentioned device can adjust the initial escape route according to the fire spread area information and the smoke spread trend information. The specific steps are as follows: Before the above-mentioned step S72, it also includes:

[0114] Obtaining the household structure of the household and constructing a three-dimensional space model based on the household structure; dividing the three-dimensional space model into rectangular spaces and marking the rectangular spaces through which the initial escape route passes;

[0115] It should be noted that the above-mentioned household structure may include the location distribution of each room area. At the same time, taking into account the impact of flammable materials on the spread of fire, the above-mentioned household structure may also include the location distribution of flammable materials in the residents' homes. Taking into account the impact of air flow on the spread of smoke, the above-mentioned household structure may also include the location distribution of ventilation openings such as windows.

[0116] It is understandable that the specific size of the above rectangular space divisions can be set according to actual conditions and is not limited in this embodiment.

[0117] It should be emphasized that the above-mentioned markings can be determined based on the initial escape route and combined with the height of the residents. For example, the ceiling of the living room is high, which is much higher than the height of the residents. If the smoke spreads only at the top, the impact will be smaller, which will facilitate the escape of residents.

[0118] In a specific implementation, the above-mentioned device can obtain the household structure of the residents, establish a three-dimensional space model based on the household structure, divide the above-mentioned three-dimensional space model into rectangular spaces, and mark the rectangular spaces passed by in combination with the initial escape route and the height of the residents.

[0119] Accordingly, the above step S72 includes: marking the divided rectangular space according to the fire spread trend information and the smoke spread trend information; and selecting a corresponding escape route from a preset escape route library according to the marking result to adjust the initial escape route.

[0120] It is understandable that the preset escape route library may store all possible escape routes, as well as rectangular space marking results corresponding to each escape route.

[0121] In a specific implementation, after marking the rectangular space through which the residents escape, the above-mentioned device can mark the rectangular space through which the fire and smoke have or will pass according to the fire spread trend information and the smoke spread trend information, and compare it with the mark of the rectangular space through which the initial escape route passes. If there is a rectangular space with the same mark, it can be determined that the rectangular space is not conducive to escape. The above-mentioned device can then select an escape route corresponding to the rectangular space that is not marked with the fire spread trend information and the smoke spread trend information from the preset escape route library, and adjust the initial escape route through the above-mentioned escape route, so that the residents can escape.

[0122] Step S73: Generate an early warning strategy based on the adjusted escape route and issue an early warning.

[0123] It should be noted that the above-mentioned equipment can send the adjusted escape route to the resident's terminal device for display.

If there are rectangular spaces with the same marks, it can be determined that the rectangular space is not conducive to escape. The aforementioned device can then select an escape route corresponding to a rectangular space not marked with the fire spread trend information and the smoke spread trend information from a preset escape route library, adjust the initial escape route based on the aforementioned escape route, and send the adjusted escape route to the resident's terminal device for display, so that the resident can use it to escape.
