[0002] An inverter is a converter that can convert direct current electrical energy (batteries, accumulators) into fixed-frequency and fixed-voltage or frequency-modulated and voltage-regulated alternating current (generally 220V, 50Hz sine wave).

[0003] In related technologies, when calibrating the time of an inverter, it is mostly through factory time setting or manual time calibration; that is, when the inverter leaves the factory, the time of the inverter is set according to the standard time zone, and when the time needs to be calibrated, the technician manually calibrates the time during installation. It can be understood that through the factory time setting method, when the inverter is moved to different time zones, time deviation will occur; while through the manual time calibration method, the operation is cumbersome and the time is easily inaccurate due to human error or omission.

[0010] In some embodiments, determining whether the inverter needs to be time-calibrated according to the current inverter time and the inverter standard time includes: calculating the difference between the current inverter time and the inverter standard time; determining whether the difference is less than a preset difference threshold; if so, it is considered that the inverter does not need to be time-calibrated.

[0011] In some embodiments, after time-calibrating the inverter according to the inverter standard time, it further includes: determining whether the time-calibration operation is successful; if not, determining whether the current failure count is greater than or equal to a preset count threshold; if the current failure count is less than the preset count threshold, increment the historical failure count by 1 and perform the time-calibration operation again; if the current failure count is greater than or equal to the preset count threshold, generate a time-calibration failure message and send the time-calibration failure message to relevant personnel.

[0022] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0023] The automatic time calibration method of the inverter according to the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0024] Please refer to Figure 1 , Figure 1 which is a schematic flowchart of the automatic time calibration method of the inverter according to the embodiments of the present invention. As shown in Figure 1 , the automatic time calibration method of the inverter includes the following steps:

[0025] S101, the collector acquires the operating state information of the inverter, and packs the operating state information into reporting data and sends it to the cloud platform.

[0026] As an example, first, the collector periodically acquires the operating state information of the inverter (such as power generation amount, real-time operating state, etc.), and packs the acquired information into reporting data and uploads it to the cloud platform.

[0027] S102, the cloud platform obtains the current inverter time based on the reporting data, and parses the IP address corresponding to the reporting data to obtain the time zone information of the collector.

[0028] In some embodiments, before the cloud platform obtains the current inverter time based on the reporting data, it further includes: judging whether the collector is reporting for the first time according to the reporting data; if not, directly parsing the reporting data to obtain the operating state information of the inverter.

[0029] That is to say, in order to reduce the computing power consumed for calibrating the inverter and avoid calibrating the time every time the reporting data sent by the collector is received. First, when the reporting data is received, the reporting data is parsed to judge whether the collector is reporting for the first time currently; if not, it means that the inverter does not need to be calibrated currently, and the reporting data is directly parsed to obtain the operating state information of the inverter, and then the process ends without calibrating the time.

[0030] It should be noted that when the installer changes the installation method of the collector and connects the collector to other inverters, the first report after the reconnection is the first report.

[0031] In some embodiments, if it is judged according to the reporting data that the collector is reporting for the first time, the reporting data is parsed to obtain the collector serial number and the inverter serial number; it is judged whether the collector and the inverter are in a bound relationship according to the collector serial number and the inverter serial number; if so, the reporting data is directly parsed to obtain the operating state information of the inverter.

[0032] In some embodiments, if the collector and the inverter are not in a bound relationship, the bound relationship between the collector and the original inverter is deleted, and the bound relationship between the collector and this inverter is established.

[0033] That is, to further prevent the inability to automatically calibrate the time due to a change in the connection method between the collector and the inverter; after determining that the current report is the first report, the reported data is parsed to obtain the collector serial number and the inverter serial number; and the relevant database is queried based on the collector serial number and the inverter serial number to determine whether the current collector and the inverter are in a bound relationship; if so, it means that the inverter does not need to be calibrated at present, and the reported data is directly parsed to obtain the inverter operation status information and then the process ends; if not, the binding relationship between the collector and the original inverter is deleted, and the binding relationship between the collector and this inverter is established. Then, the inverter is automatically calibrated.

[0034] S103, obtain the cloud platform time zone information and the current system time.

[0035] S104, calculate the inverter standard time based on the collector time zone information, the cloud platform time zone information, and the current system time.

[0036] As an example, first, the cloud platform obtains the current inverter time based on the reported data, parses the IP address in the collector request, and parses the current region where the collector is located according to the parsed IP address; then, the collector time zone information is obtained by converting according to the current region information of the collector. Then, obtain the time zone where the cloud platform is located and the current system time; then, the standard time of the time zone where the inverter is currently located can be calculated based on the collector time zone information, the time zone where the cloud platform is located, and the current system time, and this time is used as the inverter standard time.

[0037] S105, determine whether the inverter needs to be calibrated based on the current inverter time and the inverter standard time, and when the judgment result is yes, calibrate the inverter according to the inverter standard time.

[0038] In some embodiments, determining whether the inverter needs to be calibrated based on the current inverter time and the inverter standard time includes: calculating the difference between the current inverter time and the inverter standard time; determining whether the difference is less than a preset difference threshold; if so, it is considered that the inverter does not need to be calibrated.

[0039] As an example, first, calculate the difference between the current inverter time and the inverter standard time; then, determine whether the difference is less than 5S; if so, it is considered that the inverter does not need to be calibrated, and the current calibration process ends; if not, calibrate the inverter according to the inverter standard time.

[0040] In some embodiments, after calibrating the inverter according to the inverter standard time, the following steps are further included: determining whether the calibration operation is successful; if not, determining whether the current number of failure times is greater than or equal to a preset number threshold; if the current number of failure times is less than the preset number threshold, incrementing the historical number of failure times by 1 and performing the calibration operation again; if the current number of failure times is greater than or equal to the preset number threshold, generating a calibration failure message and sending the calibration failure message to relevant personnel.

[0041] As an example, after determining that the inverter needs to be calibrated, a calibration instruction is issued; if the calibration is successful, the calibration mark in the inverter file is modified to "calibrated" and the current reported data is discarded; if the calibration fails or times out, it is determined whether the current number of failure times exceeds 3; if it does not exceed, the number of failure times is incremented by 1 and the calibration instruction is issued again; if it exceeds, a calibration failure warning message is generated and the calibration failure warning message is sent to the platform operation and maintenance personnel by email.

[0042] As a specific embodiment of the present invention, as Figure 2 shown, the inverter automatic calibration method provided by the present invention includes the following steps:

[0043] S201, the collector acquires the inverter operation status information and packs the operation status information into reported data and sends it to the cloud platform.

[0049] S207, deleting the binding relationship between the collector and the original inverter and establishing a binding relationship between the collector and the inverter.

[0050] S208, the cloud platform obtains the current inverter time based on the reported data and parses the IP address corresponding to the reported data to obtain the time zone information of the collector.

[0057] S215, Determine whether the time calibration operation is successful according to the time calibration feedback information; if yes, execute step S216; if no, execute step S217.

[0059] S217, Determine whether the number of failure times is greater than the preset number threshold; if no, execute step S218; if yes, execute step S219.

[0060] S218, Increment the number of failure times by 1 and return to step S213.

[0061] S219, Generate a time calibration failure message and send the time calibration failure message to relevant personnel.
