[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0019] In the process of managing the operating data of energy storage equipment, the operating data received by the host computer is too scattered, and it is impossible to save the operating data periodically, which is inconvenient for later data retrieval and affects later maintenance. In addition, during the later data maintenance process, the time positioning of abnormal points is inaccurate, making fault analysis difficult.

[0020] like Figure 1 and Figure 3 As shown, this embodiment provides a method for managing and maintaining operation data of an energy storage device, the method comprising:

[0021] Step S1: Obtaining the daily operation data of the energy storage device.

[0022] Furthermore, the operating data includes at least: status, parameters and events of the energy storage device.

[0023] Step S2: The operation data of the day is stored in a structured manner.

[0024] Optionally, step S2 is to perform structured storage of the day's operating data through a SQL database.

[0025] Step S3. Generate the daily freeze file based on the operation data of the day and upload it to the cloud platform server.

[0026] Furthermore, after generating the daily freeze file according to the operation data of the day, it also includes:

[0027] When the storage capacity cannot save the daily frozen files or the file checking cycle is reached, the expired files in the daily frozen data files are deleted.

[0028] Furthermore, the expired file is a daily frozen data file whose difference between the number of days of the current day's frozen data file and the number of days of the earliest day's frozen data file is greater than a preset number of days.

[0029] Furthermore, the file name of the daily frozen data file is dev_YYYYMMDD.csv, wherein dev is the name of the energy storage device, YYYYMMDD is the year, month and day, and csv is the file format.

[0030] In actual application, Figure 2As shown, steps S1-S3 are managed and maintained by the energy storage data management system, which includes: a data management process, a SQL database, and a maintenance process; the data management process is used to read the operating data of the energy storage device and perform structured storage in the SQL database; the maintenance process regularly reads or transfers the operating data in the SQL database, generates a daily frozen data file for each day, and regularly deletes expired files; the maintenance process stores system operating status information in real time, and continues to record a set number of records after a fault occurs, generating a record file in CSV format; the maintenance process also performs file transfer with the FTP server to realize the export of daily frozen files and fault record files, so that maintenance personnel can perform curve drawing or fault analysis and other tasks.

[0031] In actual application, the process of obtaining the daily frozen file is as follows:

[0032] The first step is that when the energy storage data management system crosses days, that is, when the day in the time changes, the data table in the SQL database is judged for time. The data table that exceeds the required storage time will be deleted, and a new data table for the day will be created to continue storing the data for the day.

[0033] The second step is to export the data in the data table of the day into a csv data table file as the frozen file of the day when identifying cross-days. The time information is added to the file name, such as dev_YYYYMMDD.csv, where YYYYMMDD is the year, month and day, and dev is the energy storage device.

[0034] The third step is to check whether the daily frozen file (csv file) has expired. The inspection time can be set. Generally, the system idle time is selected as the inspection period. The equipment data retention period is determined according to the energy storage device. The year, month and day in the file name are used to determine whether it has expired, that is, it exceeds the set data file retention period, and it is judged as an expired file and deleted.

[0035] In the fourth step, the data file csv can be exported through the ftp server. The maintenance personnel can view the system operation records, data flow trends, switch action status, charge and discharge information records and other data based on the data records in the daily frozen file.

[0036] Step S4. Figure 4 As shown, when abnormal operation data appears in the operation data of the day, an abnormal data record file is generated and uploaded to the cloud platform server; the abnormal data record file includes half of the normal operation data and half of the abnormal operation data.

[0037] Furthermore, when abnormal operation data appears in the operation data of the day, an abnormal data record file is generated and uploaded to the cloud platform server, specifically including:

[0038] When abnormal operation data appears in the operation data of the day, the abnormal operation data at the current moment is stored in the status record table in the form of an overwritten record; the status record table is used to record the status of the energy storage device in real time; when the number of abnormal operation data reaches half of the total number of records in the status record table, an abnormal data record file is generated; and the abnormal data record file is uploaded to the cloud platform.

[0039] Optionally, the abnormal operation data at the current moment is stored in the state record table in the form of an overwritten record, specifically including:

[0040] When the status record table is not full, the abnormal operation data at the current moment will continue to be stored in sequence.

[0041] When the status record table is full, the earliest data in the status record table is deleted, and the abnormal operation data at the current moment is stored in this position.

[0042] After step S4, the method further includes:

[0043] When the number of abnormal data record files exceeds the preset number, the abnormal data record file with the earliest recording time is deleted.

[0044] Furthermore, the preset number is 50.

[0045] In actual application, the generation process of abnormal data record files is as follows:

[0046] In the first step, after the energy storage data management system is started, the operation data of the energy storage device is read at fixed time intervals and cyclically cached in the operation status record table of the data management system.

[0047] The second step is to determine whether the operating status is abnormal with the last record each time the reading is performed. If abnormal, continue to read the system operating status record after the fault and count the number of abnormal data.

[0048] In the third step, when the count reaches half of the maximum number of records that the system operation status record table can record, the entire system operation status record table stores half of the records before the fault occurs and half of the records after the fault occurs, thus obtaining a record table of the status information before and after the fault occurs.

[0049] For example: when all 50 storage locations in the running status record table are full of normal data, at this time, the record table saves normal data with serial numbers 1-50. When an abnormal data appears, the abnormal data serial number is 51. At this time, the first data No. 1 is deleted, and the data No. 51 is overwritten on the location where the original data No. 1 was located. At this time, the data serial number sequence in the running status record table is: 51, 2, 3, 4...50. At this point, 1 abnormal data (data No. 51) and 49 normal data (data No. 2-50) are saved. Similarly, when the second abnormal data appears, the abnormal data serial number is 52. Therefore, the data serial number sequence in the running status record table is: 51, 52, 3, 4...49. In this way, 2 abnormal data (data No. 51-52) and 48 normal data (data No. 2-49) are saved. By analogy, 25 normal data and 25 abnormal data are obtained.

[0050] In the fourth step, the maintenance process determines whether the fault record files exceed 50. If so, the earliest record file is deleted. If not, the records in the database are directly generated into a csv record file.

[0051] Step 5: The record file is named with the system clock, including year, month, day, hour and minute, to mark the time when the record was generated, so that maintenance personnel can query and copy it.

[0052] The present application provides an operation data management and maintenance method, equipment and medium for energy storage equipment. The operation data of the energy storage equipment is periodically stored and divided by date to generate a daily frozen data file for each day, which is convenient for later retrieval. The operation data is judged abnormally in real time, and the abnormal points are tracked and recorded. By recording half of the normal operation data and half of the abnormal operation data, it is convenient to query the time when the abnormal point occurs, and the fault is compared and analyzed based on the operation data before and after the fault at that time, which improves the efficiency of energy storage equipment fault analysis. The present application is aimed at the problems of data storage, operation status recording and fault recording of traditional energy storage systems. The present application enables maintenance personnel to quickly export data of specific dates of the system through periodic data storage and file management technology, and can analyze and count the trend or curve of the data in the form of tables or charts. It can also quickly access the record files when the fault occurs, and quickly locate the abnormal cause of the system status before and after the fault occurs.
