[0022] The technical solution of the embodiment of the present invention will be described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0023] The inverter can convert DC power into AC power and is the core device of the power generation system. Other devices in the power generation system can access the inverter data through the server. However, due to the limited communication efficiency and stability between the server and the inverter, it is not always possible to ensure that other devices can obtain effective real-time data.

[0024] Depending on whether the inverter is online, there are two paths for other devices to access the inverter data through the server. One is that when the inverter is online, the server can directly send instructions to the inverter to obtain real-time data and send it to other devices that access the inverter data. This method may be affected by the network status between the server and the inverter, resulting in untimely data acquisition. The other is that when the inverter is not online, the server can send the saved historical data of the inverter to other devices that access the inverter data. Usually, the inverter uploads the generated data to the server for storage. Due to the low performance of the inverter, the fourth generation mobile communication technology (4G) module is generally used for data transmission. However, the amount of data generated by the inverter 24 hours a day is very large, and the upload process may consume more general packet radio service (GPRS) traffic fees. In addition, the interval for uploading data is long. For example, if the inverter uploads data every 10 minutes, the data obtained by other devices between the two intervals is not the latest collected data, so it is difficult to ensure the real-time nature of the data.

[0025] Based on this, Figure 1 As shown, an embodiment of the present application provides a method for accessing inverter data, which may include steps S110-S120.

[0026] In step S110, the server receives a first request, which may be used to request data of a first inverter. The first inverter may be any inverter connected to the server, and the first request may be issued by a device other than the first inverter. For example, the first request may be issued by a mobile phone or a computer, and the mobile phone or the computer may issue the first request to the server through an application (APP).

[0027] In step S120, if the first device continuously collects data of the first inverter and uploads it to the cache of the server, the server returns the data in the cache to the device that issued the first request, otherwise the server returns the real-time data of the first inverter to the device that issued the first request. The first device can be connected to the first inverter via Bluetooth, and the first device can be a terminal device such as a mobile phone. The first device can establish a communication connection with the server, for example, communicating via a wireless local area network. The real-time data of the first inverter can be obtained based on the server's access to the first inverter, for example, the server can send instructions to the inverter to obtain real-time data.

[0028] For example, when the inverter can establish a Bluetooth connection with the first device, and the first device can establish a communication connection with the server, the first device can continuously collect and report the inverter data. Exemplarily, the first device can collect and report the first inverter data once every 5 seconds, thereby realizing continuous collection and update of the inverter data. In this case, it can be considered that the data in the server cache is real-time, so the server can return the data in the cache to the device that issued the first request.

[0029] For another example, when the inverter cannot establish a Bluetooth connection with the first device, and / or the first device cannot establish a communication connection with the server, the first device cannot continuously collect and report the inverter data. In this case, the real-time performance of the data in the server cache cannot be guaranteed, so the server needs to access the inverter to obtain real-time data and send it to the device that issued the first request. After the server returns the real-time data of the first inverter to the device that issued the first request, the real-time data can be updated in the cache.

[0030] It is worth noting that if the connection between the inverter and the server fails (i.e. the inverter is not online), but a communication connection can still be established between the server and the first device, and the first device can still establish a Bluetooth connection with the inverter, the first device can still continuously collect and report the inverter data.

[0031] In this application, if the first device can continuously collect the data of the inverter for caching and upload it to the cache of the server, the data in the cache can be directly returned to the device requesting the inverter data. Otherwise, the real-time data obtained by accessing the inverter is returned to the device requesting the inverter data. Based on this, it can be ensured that the inverter data in the server cache is updated in a timely manner, which helps to ensure that other devices obtain the real-time data of the inverter.

[0032] In some cases, multiple devices may access the inverter data through the server at the same time. In this case, if the first device cannot continuously collect the data of the first inverter and upload it to the server's cache, the server needs to access the inverter separately according to the requests of multiple devices to obtain real-time data. However, multiple accesses may cause message blocking, thereby affecting the stability and efficiency of communication.

[0033] Based on this, optionally, if the first device cannot continuously collect data from the first inverter and upload it to the cache of the server, and there is only one device that issues the first request, the server can directly access the inverter to obtain real-time data and send it to the device that issues the first request. If the first device cannot continuously collect data from the first inverter and upload it to the cache of the server, and there are multiple devices that issue the first request, the server returning the real-time data of the first inverter to the device that issues the first request may include: the server returns the real-time data to the first device that issues the first request, and stores the real-time data in the cache; the server returns the real-time data in the cache to the remaining devices that issue the first request. Based on this, access to the inverter can be reduced, which helps to improve the efficiency of the device in obtaining data.

[0034] Optional, Figure 1 The method shown may also include step S130. In step S130, if the first inverter is not online, and the first device cannot continuously collect data from the first inverter and upload it to the cache of the server, the server returns the data in the first database to the device that issued the first request. The first database is used to store historical data of the first inverter, and the data in the first database is uploaded by the first inverter. When the first inverter is not online, the server cannot directly access the first inverter to obtain data, and the first device cannot continuously collect data from the first inverter and upload it to the cache of the server, then the historical data in the first database can be sent as a return to the device that issued the first request. Based on this, when the first inverter is not online and the first device cannot continuously collect and upload data from the first inverter, it can be ensured that other devices can obtain the historical data of the first inverter.

[0035] Combine the following Figure 2 , an example is given to introduce the method for accessing inverter data in the embodiment of the present application. Figure 2 In the example, the first device is a mobile phone. The mobile phone can establish a Bluetooth connection with the inverter. The mobile phone can collect the data of the inverter through the APP and upload it to the cache of the server. And when the inverter is online, the inverter can report data to the database of the server (i.e., the first database) every 10 minutes.

[0036] like Figure 2 As shown, when the mobile phone can continuously collect the data of the inverter through the APP and upload it to the cache of the server (regardless of whether the inverter is online), the data in the server cache is constantly updated. Therefore, if the server receives the first request, whether the device that issues the first request is one or more, the server can directly return the data in the cache to the device that issues the first request.

[0037] When the mobile phone cannot collect and upload the data of the inverter and the inverter is online, if the server receives the first request, the server can determine the response strategy according to the number of devices that issued the first request. When only one device issues the first request, the server can directly access the inverter to obtain the latest data (i.e., real-time data) and return it to the device, and update the latest data in the cache. When multiple devices issue the first request, the server can access the inverter to obtain the latest data (i.e., real-time data) and return it to the first device that issued the first request, and update the latest data in the cache, and then read the latest data from the cache and return it to the remaining devices.

[0038] In addition, when the mobile phone cannot collect and upload the data of the inverter and the inverter is not online, the server cannot directly access the inverter to obtain data. At this time, if the server receives the first request, no matter there is one or more devices issuing the first request, the server can directly return the data in the database to the device issuing the first request (not shown in the figure).

[0039] based on Figure 2 The method shown can respond to devices accessing inverter data through the server according to different situations, which helps to improve the real-time performance of accessing data.

[0043] Optionally, if there are multiple devices sending the first request, the sending module 320 may be used to: Return the real-time data to the device that first issues the first request, and store the real-time data in the cache; Return the real-time data in the cache to the remaining devices that issued the first request.
