Description

Technical Field

[0001] The present application relates to the field of photovoltaic power stations, and in particular to the field of photovoltaic collector data reporting. Background Art

[0002] When the cloud platform issues instructions to control the inverter device, it needs to display the latest data of the relevant function registers on the page first. The traditional approach is to first send the read instruction, wait for the collector to collect the data of the relevant registers, and then send it to the cloud platform for display. After the reading is completed, it will be modified and the modified register data will be sent to modify the instruction. This approach is inefficient and has a high failure rate due to uncontrollable factors such as network fluctuations. In addition, the cloud platform reads the register value of the inverter device in real time, and the waiting time is long.

[0003] In view of this, this application is proposed. Summary of the invention

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Figure 1 FIG. 2 shows a schematic diagram of the structure of this embodiment. Figure 1 As shown, this embodiment includes a cloud platform 10, multiple collectors 20, and multiple inverters 30, wherein bidirectional communication can be achieved between the collectors 20 and the inverters 30, and between the cloud platform 10 and the collectors 20, that is, both data upload and command issuance can be achieved.

[0026] See again Figure 1 , the cloud platform includes a data access layer 101, a data parsing layer 102, a data storage layer 103, an application layer 104 and a presentation layer 104 which are connected in sequence.

[0027] Based on the above structure, this embodiment provides a method for quickly reporting inverter register data, including the following steps:

[0028] Step 1, the collector 20 obtains the collected data;

[0029] Preferably, after the collector 20 is powered on, it communicates with the data access layer 101 of the cloud platform 10 through the MQTT protocol. In addition, after the collector 20 is connected to the data access layer 101 of the cloud platform 10 through the MQTT protocol, it reads the inverter device type currently physically connected to the USB and sends a message for acquiring the acquisition task. It should be noted that the acquisition task of each model of inverter is pre-configured manually according to the protocol document of the inverter. The cloud platform data access layer receives the acquisition task message sent by the collector and sends the acquisition task message.

[0030] Step 2, the collector 20 uploads the collected data to the cloud platform;

[0031] Preferably, the collector receives the collection task message sent by the cloud platform access layer, communicates with the inverter using the modbusRTU protocol, starts reading the register based on the collection task message, converts it into the MQTT protocol after successful reading, and sends the data to the cloud platform data access layer once per minute.

[0032] Step 3, the cloud platform 10 preliminarily analyzes the collected data to obtain the device register number of the inverter;

[0033] Preferably, the data access layer 101 of the cloud platform 10 receives the device register data of the inverter 30 sent by the collector 20, and starts to perform preliminary analysis according to the cloud platform custom protocol. When the data analysis layer 102 of the cloud platform 10 performs preliminary analysis, it reads the device register number data of the device register of the inverter 20 obtained in step 1.

[0034] Step 4: Match the device register number with the first database of the cloud platform; if the match is successful, store the collected data in the first database and jump to step 5; otherwise, store the collected data in the second database;

[0035] Preferably, the device register number obtained in step 3 is compared with the received inverter device register number. If a match is successful, the collected data is extracted and stored in the first database; otherwise, it is stored in the second database.

[0036] Preferably, step 4 is completed in the data storage layer 103 of the cloud platform 10 .

[0037] Step 5: When the APP is started, the cloud platform 10 directly reads the collected data in the first database and directly displays it after further analysis.

[0038] Preferably, when the user opens the batch instruction page, the application layer 104 reads the inverter device control register data stored in the first database, and after further analysis, the display layer 105 displays the latest control register data of the current inverter device, thereby achieving the effect of fast reporting of the inverter device control register data without reading, and the modified inverter control register data can be directly sent down.

[0039] The "equal" or "same" or "equal" disclosed in the present invention must take into account the distribution of engineering parameters, and the error distribution is within ±30%; the definition of "parallel" of two line segments or two straight lines is that the angle between the two line segments or two straight lines is less than or equal to 45 degrees; the definition of "perpendicular" of two line segments or two straight lines is that the angle between the two line segments or two straight lines is within the range of [60, 120] degrees; the definition of "phase mismatch" also needs to take into account the distribution of engineering parameters, and the error distribution of the degree of mismatch is within ±30%. In addition, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
