Description

Technical Field

[0001] The present application belongs to the field of energy storage power supply technology, and in particular relates to an energy storage power supply monitoring method and system. Background Art

[0002] An energy storage power supply (also known as a portable energy storage power supply or mobile power system) is a device that stores electrical energy in a storage medium (such as a battery) and can output power when needed. It combines the dual functions of "storage" and "power supply." Monitoring an energy storage power supply involves obtaining the voltage or charge / discharge current of the energy storage power supply during operation and determining its health based on this information.

[0003] However, after a monitoring trigger instruction for the energy storage power supply is generated (i.e., the energy storage power supply is monitored), data on the health status of the energy storage power supply during operation may be obtained later. If, before the data is obtained, the monitoring data of the energy storage power supply fluctuates briefly and then returns to a stable value, since the data on the health status of the energy storage power supply during operation is obtained later, a stable value will be obtained at this time, and it may be mistakenly believed that the energy storage power supply is healthy, resulting in the inability to timely discover potential health problems of the energy storage power supply. Summary of the Invention

[0004] The embodiments of the present application provide a method and system for monitoring an energy storage power supply, which can solve the technical problem that after a monitoring trigger instruction for the energy storage power supply is generated, data about the health status of the energy storage power supply during operation may be obtained too late, resulting in the inability to timely discover potential health problems of the energy storage power supply.

[0005] In a first aspect, an embodiment of the present application provides a method for monitoring an energy storage power supply, which is applied to an energy storage power supply monitoring device, wherein the energy storage power supply monitoring device includes multiple monitoring units, each monitoring unit of the energy storage power supply monitoring device is used to monitor whether the energy storage power supply is abnormal. The method includes: When a monitoring trigger instruction is obtained, preprocessing is performed on the main monitoring unit, and processing information is determined based on the preprocessing of the main monitoring unit; wherein the preprocessing includes at least one of determining whether the current monitoring unit is normal, setting a basic monitoring object, waking up the current monitoring unit, calibrating the zero point, and deleting historical data remaining from the previous monitoring task; the processing information is used to reflect the processing status of the main monitoring unit; the main monitoring unit is one of the multiple monitoring units of the energy storage power supply monitoring device; Get monitoring confirmation instructions; When it is determined that the monitoring confirmation instruction triggers a monitoring unit for monitoring whether the energy storage power supply is abnormal, determining whether the triggered monitoring unit is the main monitoring unit; In the case where it is determined that the triggered monitoring unit is the main monitoring unit, determining whether the pre-processing action on the main monitoring unit is completed according to the processing information; When it is determined that the preprocessing action of the main monitoring unit is completed, the step of preprocessing the main monitoring unit is no longer executed. At the same time, the corresponding working data of the basic monitoring object set in the preprocessing is determined according to the monitoring confirmation instruction to control the main monitoring unit to obtain power supply data; wherein, the power supply data is used to reflect the health status of the energy storage power supply during operation.

[0006] The above technical solutions in the embodiments of the present application have at least the following technical effects: The energy storage power supply monitoring method provided by the present application can pre-process the main monitoring unit when the monitoring trigger instruction is obtained, regardless of the current situation. When it is determined that the monitoring unit for monitoring whether the energy storage power supply is abnormal is indeed triggered, and the triggered monitoring unit is indeed the main monitoring unit, it can be determined whether the pre-processing action on the main monitoring unit is completed. When it is determined that the pre-processing action on the main monitoring unit is completed, there is no need to run the steps of pre-processing the main monitoring unit, but directly control the main monitoring unit to obtain power data, that is, the main monitoring unit is pre-processed, and data on the health status of the energy storage power supply during operation can be obtained earlier. Even if the monitoring data of the energy storage power supply fluctuates briefly and then returns to a stable value, the short-term fluctuation data can be obtained, thereby timely discovering potential health problems of the energy storage power supply.

[0007] In a possible implementation of the first aspect, when it is determined that the triggered monitoring unit is the primary monitoring unit, after determining, based on the processing information, whether the preprocessing action on the primary monitoring unit is completed, the method further includes: When it is determined that the pre-processing action on the main monitoring unit has not been completed, the main monitoring unit is controlled to obtain the power data after the pre-processing action on the main monitoring unit is completed.

[0008] In a possible implementation of the first aspect, when it is determined that the monitoring confirmation instruction triggers a monitoring unit for monitoring whether the energy storage power supply is abnormal, after determining whether the triggered monitoring unit is the main monitoring unit, the method further includes: When it is determined that the triggered monitoring unit is a secondary monitoring unit, the secondary monitoring unit is preprocessed and then controlled to obtain the power data; wherein the secondary monitoring unit is one of the multiple monitoring units of the energy storage power supply monitoring device.

[0009] In a possible implementation of the first aspect, when it is determined that the triggered monitoring unit is the secondary monitoring unit, preprocessing the secondary monitoring unit, and then controlling the secondary monitoring unit to obtain the power data includes: In the case where it is determined that the triggered monitoring unit is the secondary monitoring unit, determining whether the pre-processing action on the primary monitoring unit is completed; When it is determined that the pre-processing action on the main monitoring unit is completed, the main monitoring unit is controlled to stop, the sub-monitoring unit is pre-processed, and then the sub-monitoring unit is controlled to obtain the power data.

[0010] In a possible implementation of the first aspect, the method further includes: Analyzing and processing the processing information; wherein, at the moment of currently analyzing and processing the processing information, if the pre-processing action of the main monitoring unit is completed, the processing information is reflected as the preset information; In a case where the processing information reflects the preset information, it is determined that the pre-processing action on the main monitoring unit is completed.

[0011] In a possible implementation of the first aspect, when it is determined that the preprocessing action on the main monitoring unit has not been completed, waiting for the preprocessing action on the main monitoring unit to be completed, and then controlling the main monitoring unit to obtain power data includes: Analyzing and processing the processing information; wherein, at the moment of analyzing and processing the processing information, if the pre-processing action of the main monitoring unit has not been completed, the processing information is reflected as designated information; When the processing information reflects the designated information, it is determined that the preprocessing action on the main monitoring unit has not been completed, and after the preprocessing action on the main monitoring unit is completed, the main monitoring unit is controlled to obtain the power data.

[0012] In a possible implementation of the first aspect, when it is determined that the triggered monitoring unit is the primary monitoring unit, determining, based on the processing information, whether a preprocessing action on the primary monitoring unit is completed includes: When it is determined that the type of the monitoring unit triggered to monitor whether the energy storage power supply is abnormal matches the type of the main monitoring unit, it is determined that the triggered monitoring unit is the main monitoring unit, and then, based on the processing information, it is determined whether the preprocessing action on the main monitoring unit is completed.

[0013] In a possible implementation of the first aspect, the monitoring trigger instruction is used to trigger the main monitoring unit or the secondary monitoring unit to perform abnormal monitoring of the energy storage power supply, or the monitoring trigger instruction is used to trigger the power query unit to query the power.

[0014] In a possible implementation of the first aspect, the method further includes: When it is determined that the monitoring confirmation instruction triggers a monitoring unit that is not used to monitor whether the energy storage power supply is abnormal, the operation is stopped and the main monitoring unit is pre-processed according to the monitoring trigger instruction. At the same time, the steps for processing information are determined based on the situation of pre-processing the main monitoring unit.

DETAILED DESCRIPTION

[0020] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details.

[0022] It will also be understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0023] As used in this specification and the appended claims, the term "if" can be interpreted as "when" or "upon" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined" or "if the described condition or event is detected" can be interpreted as meaning "upon determination" or "in response to determining" or "upon detection of the described condition or event" or "in response to detecting the described condition or event," depending on the context.

[0024] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0025] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof all mean "including but not limited to," unless otherwise specifically emphasized.

[0026] In related technologies, monitoring of energy storage power supplies generally includes the following processes: Process ①: Obtain a monitoring trigger command (such as clicking or touching the interactive screen of the energy storage power supply monitoring device). The energy storage power supply monitoring system will set up an interactive box based on the monitoring trigger command to determine the monitoring business (such as monitoring the voltage or current of the energy storage power supply at location a, monitoring the voltage or current of the energy storage power supply at location b, monitoring the voltage or current of the energy storage power supply at location c, monitoring the voltage or current of a battery cell in the energy storage power supply at location a, etc.).

[0027] Process ②: After the steps described above are completed, the energy storage power supply monitoring system will run to determine whether the current monitoring unit is normal, set basic monitoring objects (such as loading monitoring objects, for example, loading basic current, voltage, temperature and other monitoring objects. Since the objects of different monitoring tasks are not exactly the same, if the objects of the previous monitoring task are not deleted, the objects of the previous monitoring task will be used, and the objects of the current monitoring task are not included in the objects of the previous monitoring task, then it may not be able to meet the current monitoring needs. Therefore, after each monitoring task is completed, all monitoring objects loaded by the previous monitoring task will be deleted. Since all loaded monitoring objects are deleted at the end of each monitoring task, there will be no monitoring objects when the monitoring trigger instruction is obtained. Therefore, in process ②, the basic monitoring objects must be reloaded. Therefore, the basic monitoring objects must be set in each monitoring task), wake up the current monitoring unit, calibrate the zero point, and delete the remaining historical data in the previous monitoring task.

[0028] Process ③: After the steps described above are completed, the energy storage power supply monitoring system will configure the monitoring objects for the monitoring unit based on the monitoring requirements (such as the user-defined sampling frequency, data accuracy, and anomaly thresholds). For example, if the previously loaded monitoring object is current, the current sampling range will be set accordingly; if the previously loaded monitoring object is temperature, the temperature monitoring refresh frequency will be set accordingly. For example, since different monitoring tasks focus on different objects (some focus on current, others on voltage, temperature, etc.), the previously defined basic monitoring objects can be conditionally filtered, such as deleting objects of no interest, retaining objects of interest, and configuring the corresponding working data (such as sampling frequency, data accuracy, anomaly thresholds, etc.) for the retained objects. Since the monitoring requirements vary each time, the steps for configuring the monitoring objects for the monitoring unit will also be different each time.

[0029] Process ④: After the above steps are completed, the energy storage power supply monitoring system controls the monitoring unit to collect data such as voltage, current, and battery cell temperature in real time.

[0030] In the traditional energy storage power supply monitoring technology described above, such as Figure 3As shown, it may take a long time from process ① to process ②, and it may also take a long time from process ② to process ③. Since process ④ must be carried out after process ①, process ② and process ③ are completed, according to traditional energy storage power supply monitoring technology, data on the health status of the energy storage power supply during operation may be obtained later. If the monitoring data of the energy storage power supply fluctuates briefly before the data is obtained and then returns to a stable value, since the data on the health status of the energy storage power supply during operation is obtained later, a stable value will be obtained at this time, and it may be mistakenly believed that the energy storage power supply is healthy, resulting in the inability to timely discover potential health problems of the energy storage power supply.

[0031] A detailed description of the "possible length of time required to transition from process 1 to process 2" is provided. For example, if an energy storage power supply runs out of power and needs to be disconnected from the current energy storage power supply monitoring system and recharged in a dedicated power supply system, the monitoring service determined each time according to the monitoring trigger instruction in process 1 may be different. For example, the first monitoring service determined includes monitoring the voltage or current of the energy storage power supply at location a, the voltage or current of the energy storage power supply at location b, and the voltage or current of the energy storage power supply at location c. Later, because the energy storage power supply at location b runs out of power and is disconnected from the current energy storage power supply monitoring system, a new energy storage power supply is added to replace the energy storage power supply at location b. Therefore, the second monitoring service determined includes monitoring the voltage or current of the energy storage power supply at location a and the voltage or current of the new energy storage power supply at location b. This means that the energy storage power supply monitoring system needs time to generate a new button (i.e., the button for monitoring the voltage or current of the new energy storage power supply at location b) each time for the operation and maintenance personnel to select (this selection also takes time), thereby determining the current monitoring service. Therefore, each monitoring service determined by the monitoring trigger instruction in process 1 takes some time.

[0032] A detailed description of "Process ② to Process ③ may also take a long time." Process ② runs the steps of determining whether the current monitoring unit is normal, setting the basic monitoring objects, waking up the current monitoring unit, calibrating the zero point, and deleting the historical data remaining from the previous monitoring task. This also takes some time. If some monitoring units are relatively old, the time taken may be even longer.

[0033] To solve the above problems, the embodiments of the present application provide a method and system for monitoring an energy storage power supply.

[0034] In this method, when the monitoring trigger instruction is obtained, no matter what the current situation is, the main monitoring unit is preprocessed first, that is, when the monitoring service is determined according to the monitoring trigger instruction setting, and before running process ②, the main monitoring unit can be preprocessed. When it is determined that it is indeed the monitoring unit that is triggered to monitor whether the energy storage power supply is abnormal, and the triggered monitoring unit is indeed the main monitoring unit, it can be determined whether the preprocessing action on the main monitoring unit is completed. When it is determined that the preprocessing action on the main monitoring unit is completed, there is no need to run the steps of preprocessing the main monitoring unit, but directly control the main monitoring unit to obtain power data. Since the main monitoring unit can be preprocessed when the monitoring service is determined according to the monitoring trigger instruction setting, and before running process ②, there is no need to perform process ② after process ① is completed. Therefore, the subsequent processes ③ and ④ can be completed quickly compared with the previous ones because the time from process ① to process ③ is shortened (such as Figure 4 Therefore, data on the health status of the energy storage power supply during operation can be obtained earlier. Even if the monitoring data of the energy storage power supply fluctuates briefly and then returns to a stable value, the previous brief fluctuation data can be obtained, thereby promptly discovering potential health problems of the energy storage power supply.

[0035] The energy storage power supply monitoring method provided in the embodiment of the present application can be applied to an energy storage power supply monitoring device. In this case, the energy storage power supply monitoring device is the execution entity of the energy storage power supply monitoring method provided in the embodiment of the present application. The embodiment of the present application does not impose any restrictions on the specific type of the energy storage power supply monitoring device.

[0036] For example, the energy storage power supply monitoring device may include a multifunctional monitoring unit (such as a sensing and acquisition unit, used to sample key signals, including single or group voltage sensors, current sensors, temperature sensors, humidity sensors, and may also include gas sensors, etc.) and a control board (used to control the multifunctional monitoring unit to monitor the current, voltage, temperature, power, etc. of the lithium battery cell).

[0037] See also Figure 2 The energy storage power supply may be a lithium battery energy storage power supply, a square aluminum shell lithium battery energy storage power supply, or the like. The energy storage power supply may include a lithium battery cell, and the material of the lithium battery cell may be lithium cobalt oxide, lithium manganese oxide, ternary lithium, lithium iron phosphate, or the like. The energy storage power supply monitoring device may be disposed inside the energy storage power supply and electrically connected to the energy storage power supply, or may be disposed outside the energy storage power supply and electrically connected to the energy storage power supply. The energy storage power supply monitoring device may monitor the current, voltage, temperature, power, etc. of the lithium battery cell.

[0038] In order to better understand the energy storage power supply monitoring method provided in the embodiment of the present application, the specific implementation process of the energy storage power supply monitoring method provided in the embodiment of the present application is exemplarily introduced below.

[0039] Figure 1 A schematic flow chart of a method for monitoring an energy storage power supply provided in an embodiment of the present application is shown. The method for monitoring an energy storage power supply includes: S100: Upon receiving a monitoring trigger instruction, preprocess the main monitoring unit and determine processing information based on the preprocessing of the main monitoring unit. Preprocessing includes at least one of determining whether the current monitoring unit is functioning properly, setting basic monitoring targets, waking up the current monitoring unit, calibrating the zero point, and deleting any remaining historical data from the previous monitoring task. The processing information reflects the processing status of the main monitoring unit. The main monitoring unit is one of the multiple monitoring units in the energy storage power supply monitoring device.

[0040] It is understood that the monitoring trigger instruction is used to trigger the main monitoring unit or the secondary monitoring unit to monitor the energy storage power supply for abnormalities, or the monitoring trigger instruction is used to trigger the power query unit to query the power level. Both the main monitoring unit and the secondary monitoring unit can be multifunctional monitoring units (such as sensing and acquisition units for sampling key signals, including single or group voltage sensors, current sensors, temperature sensors, humidity sensors, and may also include gas sensors).

[0041] For example, a monitor may be configured to obtain a monitoring trigger instruction for the energy storage power supply.

[0042] In traditional technical solutions, after the operator clicks the "Start Monitoring" option box on the interactive screen or keypad, the system will provide a button (such as a health monitoring button or a power monitoring button). Based on the button the operator selects, the system will then set up monitoring services (e.g., monitoring the voltage or current of the energy storage power supply at location a, monitoring the voltage or current of the energy storage power supply at location b, monitoring the voltage or current of the energy storage power supply at location c, monitoring the voltage or current of a specific cell in the energy storage power supply at location a, monitoring the power consumption of the energy storage power supply at location a, monitoring the power consumption of the energy storage power supply at location b, etc.), and then provide the operator with the options. Only after the above steps are completed will process ② begin.

[0043] In this application, once the operation and maintenance personnel clicks the "Start Monitoring" button on the interactive screen or key panel, whether it is to monitor the power consumption, the health of the energy storage power supply during operation, or the voltage or current of the energy storage power supply at a certain point, it is directly assumed that the current operation and maintenance personnel's intention is to monitor whether the energy storage power supply is abnormal. Therefore, the main monitoring unit can be pre-processed, that is, no matter what the situation is, the main monitoring unit is directly pre-processed (such as Figure 3As shown in FIG2 , furthermore, since the main monitoring unit is pre-processed directly when the monitoring service is determined according to the monitoring trigger instruction setting and before running process ②, if the current operation and maintenance personnel subsequently intend to monitor whether the energy storage power supply is abnormal, the time for actually performing process ② is also shortened (for example, if process ② is actually entered, since the main monitoring unit has been pre-processed before, processes ③ and ④ can be directly entered. That is, since the time from process ① to process ③ is shortened, subsequent processes ③ and ④ can be completed more quickly than before, without having to be performed after processes ① and ② are completed as in traditional technology). Therefore, data on the health status of the energy storage power supply during operation can be obtained earlier, without having to perform process ② after process ① is completed, which results in the inability to timely discover potential health problems of the energy storage power supply.

[0044] It can be understood that judging whether the current monitoring unit is normal can be judging whether the current monitoring unit is healthy and whether the resources are sufficient. Calibration zero point is used to correct the zero point deviation of the sensor. Waking up the current monitoring unit is used to indicate that the monitoring unit is in working state. Setting the basic monitoring object is used to load the monitoring object to be monitored (such as loading the basic current, voltage, temperature and other monitoring objects, and the subsequent process ③ is only used to set the corresponding sampling frequency, data accuracy, abnormal threshold, etc. on this basis, and, if the subsequent monitoring needs only require monitoring current, the subsequent process ③ is only used to set the corresponding sampling frequency, data accuracy, abnormal threshold, etc. on the basic current, and other basic monitoring objects can be deleted). Deleting the remaining historical data from the previous monitoring task indicates deleting or resetting the cache, temporary tables, or logs remaining in the memory or database from the previous monitoring task. (For example, in the previous monitoring task, the current sampling frequency was 1-5 Hz, the data accuracy was 0.1, and the abnormality threshold was 5.5 A. In the next monitoring task, the current sampling frequency was 10-15 Hz, the data accuracy was 0.01, and the abnormality threshold was 9.85 A. Therefore, the data cannot be affected by the historical data from the previous monitoring task, so the remaining historical data from the previous monitoring task needs to be deleted.)

[0045] For example, when a monitoring trigger instruction is received, whether it is monitoring power consumption, monitoring the health of the energy storage power supply during operation, or monitoring the voltage or current of the energy storage power supply at a specific point, the main monitoring unit can be pre-processed directly. That is, when the monitoring service is determined according to the monitoring trigger instruction setting, and before the actual operation of process 2, the main monitoring unit can be pre-processed, without having to perform process 2 after process 1. At the same time, based on the results of the pre-processing of the main monitoring unit, processing information used to reflect the processing status of the main monitoring unit can be determined.

[0046] With this configuration, the pre-processing of the main monitoring unit is completed before the actual monitoring operation process (such as process ②) is entered, reducing the time of "processing after triggering and completing the confirmed monitoring business", and providing data support for the subsequent faster acquisition of data on the health status of the energy storage power supply during operation.

[0047] S200: Obtain a monitoring confirmation instruction.

[0048] It is understood that the monitoring confirmation instruction is used to confirm the current monitoring task, such as the task of monitoring health, the task of monitoring power, the sampling frequency of monitoring data, data accuracy, abnormal threshold, etc.

[0049] For example, after the operation and maintenance personnel clicks the "Start Monitoring" option box on the interactive screen or button panel, the system will provide a button (such as a button for monitoring health, a button for monitoring power, etc.), and then obtain the monitoring confirmation instruction based on the button selected by the operation and maintenance personnel.

[0050] This setting can provide data support for subsequent steps.

[0051] S300: When it is determined that the monitoring confirmation instruction triggers a monitoring unit for monitoring whether the energy storage power supply is abnormal, determine whether the triggered monitoring unit is a main monitoring unit.

[0052] It can be understood that when it is determined that the monitoring confirmation instruction triggers the monitoring unit used to monitor whether the energy storage power supply is abnormal, it means that the current intention of the operation and maintenance personnel is to monitor whether the energy storage power supply is abnormal, rather than to monitor the power of the energy storage power supply. That is, assuming that "the current intention of the operation and maintenance personnel is to obtain the monitoring of whether the energy storage power supply is abnormal" is half right (that is, to monitor whether the energy storage power supply is abnormal through the monitoring unit). Therefore, in order to further verify that the previous step of pre-processing the main monitoring unit is effective, that is, to verify that the previous step of pre-processing the main monitoring unit is not in vain, it can be further determined whether the triggered monitoring unit is the main monitoring unit.

[0053] Such a setting can verify that the previous pre-processing step of the main monitoring unit is effective, and provide data support for obtaining data about the health status of the energy storage power supply during operation more quickly in the future.

[0054] S400: When it is determined that the triggered monitoring unit is the main monitoring unit, it is determined whether the pre-processing action on the main monitoring unit is completed according to the processing information.

[0055] It can be understood that the processing information can reflect that the preprocessing action of the main monitoring unit is completed, or it can reflect that the preprocessing action of the main monitoring unit is not completed, or it can reflect that the preprocessing action of the main monitoring unit is not completed but has started, or it can reflect that the preprocessing action of the main monitoring unit has not started.

[0056] For example, when it is determined that the triggered monitoring unit is the main monitoring unit, it means that the previous pre-processing steps for the main monitoring unit are valid, that is, it is verified that the previous pre-processing steps for the main monitoring unit are not in vain, that is, it is assumed that "the current intention of the operation and maintenance personnel is to obtain whether the monitored energy storage power supply is abnormal". Therefore, the processing information can be read to obtain the result of whether the pre-processing action for the main monitoring unit is completed.

[0057] With such a setting, when it is determined that the triggered monitoring unit is the main monitoring unit, whether the preprocessing action of the main monitoring unit is completed is determined based on the processing information, which can provide data support for whether to re-run the preprocessing step of the main monitoring unit in the future.

[0058] In one possible implementation, in step S400, when it is determined that the triggered monitoring unit is the main monitoring unit, after determining whether the pre-processing action on the main monitoring unit is completed based on the processing information, the energy storage power supply monitoring method further includes: S410 , when it is determined that the pre-processing action on the main monitoring unit has not been completed, wait until the pre-processing action on the main monitoring unit is completed, and then control the main monitoring unit to obtain power data.

[0059] It is understood that if the pre-processing action on the main monitoring unit is determined to be not completed, the system will continue to record the change event of the pre-processing state of the main monitoring unit. If the pre-processing is completed, the action of obtaining power data is triggered, that is, the main monitoring unit is controlled to obtain power data.

[0060] With this setup, acquisition will only begin after the preprocessing step is actually complete, avoiding inconsistent data or erroneous readings when the sensor is not ready.

[0061] S500: If it is determined that the pre-processing action for the main monitoring unit is completed, the pre-processing step for the main monitoring unit is no longer performed. At the same time, the operating data corresponding to the basic monitoring object set in the pre-processing is determined according to the monitoring confirmation instruction to control the main monitoring unit to obtain power supply data. The power supply data is used to reflect the health status of the energy storage power supply during operation.

[0062] It can be understood that the power supply data may be data such as current, voltage, temperature, etc. of the energy storage power supply during operation.

[0063] For example, when it is determined that the preprocessing action of the main monitoring unit is completed, it means that the preprocessing of the main monitoring unit has been completed, that is, when the monitoring business is determined according to the monitoring trigger instruction setting, and before running process ②, the preprocessing of the main monitoring unit has been completed, and there is no need to run the steps of preprocessing the main monitoring unit (that is, actually running process ②), but you can directly perform process ③ and process ④ (that is, according to the monitoring confirmation instruction, set the current sampling range corresponding to the current when the previously loaded monitoring object is set to be current, set the temperature monitoring refresh frequency corresponding to the previously loaded monitoring object to be temperature, delete the objects that are not concerned, retain the objects that are concerned, and set the corresponding working data (such as sampling frequency, data accuracy, abnormality threshold, etc.) for the retained objects), control the monitoring unit to collect in real time to obtain power supply data.

[0064] With this arrangement, when the monitoring service is determined according to the monitoring trigger instruction setting and before running process ②, the main monitoring unit can be pre-processed, without having to perform process ② after process ①. Therefore, subsequent processes ③ and ④ can also be completed quickly. Therefore, data on the health status of the energy storage power supply during operation can be obtained earlier. Even if the monitoring data of the energy storage power supply fluctuates briefly and then returns to a stable value, the previous brief fluctuation data can be obtained, thereby promptly discovering potential health problems of the energy storage power supply.

[0065] In one possible implementation, see Figure 5 In step S300, when it is determined that the monitoring unit for monitoring whether the energy storage power supply is abnormal is triggered, after determining whether the triggered monitoring unit is a main monitoring unit, the energy storage power supply monitoring method further includes: S510 : When it is determined that the triggered monitoring unit is a secondary monitoring unit, pre-process the secondary monitoring unit, and then control the secondary monitoring unit to obtain power data.

[0066] It can be understood that the secondary monitoring unit is one of the multiple monitoring units of the energy storage power supply monitoring device. The difference between the main monitoring unit and the secondary monitoring unit is that the acquisition speed of the main monitoring unit is faster than that of the secondary monitoring unit. Therefore, the probability of using the main monitoring unit to obtain data on the energy storage power supply is greater than the probability of using the secondary monitoring unit to obtain data on the energy storage power supply.

[0067] For example, when it is determined that the triggered monitoring unit is a secondary monitoring unit, the secondary monitoring unit can be pre-processed. That is, regardless of whether the monitoring is for power consumption, for monitoring the health of the energy storage power supply during operation, or for monitoring the voltage or current of the energy storage power supply at a certain point, it is directly assumed that the current operation and maintenance personnel's intention is to monitor whether the energy storage power supply is abnormal, and the secondary monitoring unit is directly pre-processed. In this way, if the current operation and maintenance personnel's intention is indeed to monitor whether the energy storage power supply is abnormal, data on the health status of the energy storage power supply during operation can be obtained earlier based on the secondary monitoring unit, without having to perform process 2 after process 1 is completed, resulting in the inability to timely discover potential health problems of the energy storage power supply.

[0068] With this arrangement, when determining the monitoring service according to the monitoring trigger instruction setting and before running process ②, the secondary monitoring unit can be pre-processed, without having to perform process ② after process ① is completed. Therefore, subsequent processes ③ and ④ can also be completed quickly, which can avoid the possibility of obtaining data on the health status of the energy storage power supply during operation later after the monitoring trigger instruction for the energy storage power supply is generated, resulting in the inability to timely discover potential health problems of the energy storage power supply.

[0069] In one possible implementation, in S510, if it is determined that the triggered monitoring unit is a secondary monitoring unit, preprocessing the secondary monitoring unit and then controlling the secondary monitoring unit to obtain power data may include: S511: When it is determined that the triggered monitoring unit is a secondary monitoring unit, determine whether the pre-processing action on the primary monitoring unit is completed.

[0070] It can be understood that when it is determined that the triggered monitoring unit is a secondary monitoring unit, the processing information can be read to obtain the result of whether the preprocessing action on the main monitoring unit is completed, that is, to determine whether the preprocessing action on the main monitoring unit is completed.

[0071] With such an arrangement, by determining whether the pre-processing action on the main monitoring unit is completed, data support can be provided for subsequent processing on the main monitoring unit.

[0072] S512: When it is determined that the pre-processing action on the main monitoring unit is completed, the main monitoring unit is controlled to stop, the sub-monitoring unit is pre-processed, and then the sub-monitoring unit is controlled to obtain power data.

[0073] It is understood that if it is determined that the pre-processing action on the main monitoring unit has ended, the main monitoring unit can be controlled to stop and pre-processing can be performed on the secondary monitoring unit. If the processing information shows that the pre-processing action on the main monitoring unit has not started, then when the monitoring trigger instruction is obtained, pre-processing is not performed on the main monitoring unit, but on the secondary monitoring unit. The secondary monitoring unit is then controlled to obtain power supply data.

[0074] With this setup, when a secondary monitoring unit scenario is triggered, preprocessing on the primary monitoring unit (if not already started) can be skipped and preprocessing on the secondary monitoring unit can be performed directly. This reduces irrelevant operations and allows the secondary monitoring unit to be preprocessed quickly. When the primary monitoring unit is ready, it is stopped promptly to free up resources for the secondary monitoring unit. This avoids functional redundancy caused by "dual unit parallelism" (for example, the primary and secondary monitoring units simultaneously collect the same parameters, resulting in duplicate data processing) and saves system computing power.

[0075] In one possible implementation, the energy storage power supply monitoring method further includes: S520: Analyze and process the processed information. If the pre-processing action on the main monitoring unit is completed at the moment of analyzing and processing the processed information, the processed information is reflected as the preset information.

[0076] It will be appreciated that the currently stored or most recent processing information is obtained. The processing information includes multiple status fields, such as whether the pre-processing action of the main monitoring unit has been completed or whether the pre-processing action of the main monitoring unit has not been completed. If the pre-processing action of the main monitoring unit has been completed at the time the processing information is currently being analyzed and processed, the processing information is reflected as preset information. If the pre-processing action of the main monitoring unit has not been completed at the time the processing information is currently being analyzed and processed, the processing information is reflected as specified information.

[0077] With this configuration, by dividing the processed information into two categories, "preset information" and "specified information", the system can proceed to subsequent steps according to certain rules.

[0078] S530: When the processed information reflects the preset information, it is determined that the pre-processing action on the main monitoring unit is completed.

[0079] It can be understood that the latest processing information is read to obtain the processing status of the main monitoring unit. When analyzing the processing information, if the processing information reflects the preset information, it is determined that the preprocessing action on the main monitoring unit is completed.

[0080] This setting helps ensure that subsequent actions are performed in the correct system state.

[0081] In one possible implementation, in step S410, if it is determined that the pre-processing action on the main monitoring unit has not been completed, then waiting for the pre-processing action on the main monitoring unit to be completed before controlling the main monitoring unit to obtain power data includes: S540: Analyze and process the processed information. If the pre-processing action on the main monitoring unit has not been completed at the moment of analyzing and processing the processed information, the processed information is reflected as the designated information.

[0082] It is understood that the currently stored or latest processing information is obtained. The processing information includes multiple status fields, such as whether the pre-processing action of the main monitoring unit has been completed or whether the pre-processing action of the main monitoring unit has not been completed. At the moment of analyzing and processing the processing information, if the pre-processing action of the main monitoring unit has not been completed, the processing information reflects the specified information.

[0083] With this configuration, by dividing the processed information into two categories, "preset information" and "specified information", the system can proceed to subsequent steps according to certain rules.

[0084] S550: When the processed information reflects the specified information, it is determined that the pre-processing action on the main monitoring unit has not been completed, and the pre-processing action on the main monitoring unit is waited for to be completed before controlling the main monitoring unit to obtain power data.

[0085] It can be understood that the latest processing information is read to obtain the processing status of the main monitoring unit. When analyzing the processing information, if the processing information reflects the specified information, it is determined that the pre-processing action on the main monitoring unit has not yet been completed. If the pre-processing action on the main monitoring unit is determined to have not yet been completed, the system will continue to record the change event of the pre-processing status of the main monitoring unit. If the pre-processing action has been completed, the action of obtaining power data is triggered, that is, the main monitoring unit is controlled to obtain power data.

[0086] With this setup, acquisition will only begin after the preprocessing step is actually complete, avoiding inconsistent data or erroneous readings when the sensor is not ready.

[0087] In one possible implementation, in S400, when it is determined that the triggered monitoring unit is the primary monitoring unit, determining whether the pre-processing action on the primary monitoring unit is completed based on the processing information includes: When it is determined that the type of the monitoring unit triggered for monitoring whether the energy storage power supply is abnormal matches the type of the main monitoring unit, it is determined that the triggered monitoring unit is the main monitoring unit, and then based on the processing information, it is determined whether the preprocessing action on the main monitoring unit is completed.

[0088] It can be understood that the system extracts the type of monitoring unit to be triggered from the log, compares the type of the monitoring unit to be triggered with the type of the main monitoring unit, and if the two are the same, it is determined that the main monitoring unit is triggered this time; if they are different, it is determined that the main monitoring unit is not triggered this time. In the case where it is determined that the triggered monitoring unit is the main monitoring unit, it means that the previous pre-processing steps of the main monitoring unit are effective, that is, it verifies that the previous pre-processing steps of the main monitoring unit were not in vain, that is, the assumption that "the current operation and maintenance personnel's intention is to obtain whether the monitored energy storage power supply is abnormal" is valid, therefore, the processing information can be read to obtain the result of whether the pre-processing action on the main monitoring unit has been completed.

[0089] Such a setting can verify that the previous pre-processing step of the main monitoring unit is effective, and provide data support for obtaining data about the health status of the energy storage power supply during operation more quickly in the future.

[0090] In a possible implementation, the monitoring trigger instruction is used to trigger the main monitoring unit or the secondary monitoring unit to perform abnormal monitoring of the energy storage power supply, or the monitoring trigger instruction is used to trigger the power query unit to query the power.

[0091] In one possible implementation, the energy storage power supply monitoring method further includes: When it is determined that the monitoring unit triggered is not the one for monitoring whether the energy storage power supply is abnormal, the operation is stopped and the main monitoring unit is preprocessed according to the monitoring trigger instruction. At the same time, the steps for processing information are determined based on the preprocessing of the main monitoring unit.

[0092] It can be understood that when it is determined that the monitoring unit triggered is not the one used to monitor whether the energy storage power supply is abnormal, it means that the current operation and maintenance personnel's intention is not to obtain the monitoring of whether the energy storage power supply is abnormal. Therefore, the operation can be stopped according to the monitoring trigger instruction, and the main monitoring unit can be pre-processed. At the same time, the steps for processing information are determined based on the pre-processing of the main monitoring unit.

[0093] Optionally, the step of preprocessing the main monitoring unit does not affect the step of determining whether the monitoring unit for monitoring the energy storage power supply is abnormal, and the two steps can be performed simultaneously. If it is determined that the monitoring unit for monitoring the energy storage power supply is not triggered, the preprocessing of the main monitoring unit according to the monitoring trigger instruction can be stopped in a timely manner. At the same time, the step of processing the information is determined based on the preprocessing of the main monitoring unit. In this way, even if the assumption that "the current operation and maintenance personnel's intention is to obtain information on monitoring the energy storage power supply is abnormal" is not true, the action of preprocessing the main monitoring unit according to the monitoring trigger instruction can be stopped in a timely manner, freeing up the resources occupied by the preprocessing.

[0094] With this setup, the operational intent and the actual system behavior can be executed separately. When the business intent is inconsistent with the pre-processing, unnecessary actions can be automatically and protectively interrupted.

[0095] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
