[0054] 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.

[0055] Embodiment 1: This application discloses a method for collecting logs of a photovoltaic tracking bracket system.

[0056] For details, please refer to Figure 1 The method for collecting logs of a photovoltaic tracking bracket system disclosed in this embodiment includes the following steps:

[0057] Step 101: The NCU receives a log collection instruction sent remotely.

[0058] In the method described in this embodiment, each array of the photovoltaic tracking bracket system includes an NCU and several TCUs. The NCU can be connected to the monitoring platform through the MQTT protocol (a message transmission protocol based on the publish-subscribe mode), and the NCU and all TCUs corresponding to the NCU can form a local area network through lora and / or zigbee.

[0059] The method described in this embodiment can be implemented by a pre-established monitoring platform. As an optional method, the user can remotely send a log collection instruction including the identifier of the target TCU to the NCU corresponding to the target TCU through the monitoring platform based on the target TCU. Among them, the user can be a maintenance personnel or a system that supports monitoring the status of the TCU. The target TCU can be a TCU in an abnormal state or a TCU in a normal state. For example, in one case, the maintenance personnel wants to check the status of the first TCU, and then remotely send a log collection instruction including the identifier of TCU No. 1 to the NCU corresponding to TCU No. 1 through the monitoring platform. In another case, an abnormality occurs in TCU No. 1, and the system that supports monitoring the status of TCU detects the abnormality, and then automatically sends a log collection instruction including the identifier of TCU No. 1 to the NCU corresponding to TCU No. 1 through the monitoring platform. The specific types of users and target TCUs are not limited here, and the above method can be implemented.

[0060] In the method described in this embodiment, there can be multiple target TCUs, and the multiple target TCUs can correspond to the same NCU or different NCUs. For example, in one case, the target TCUs are TCU No. 2 and TCU No. 3, and TCU No. 2 corresponds to NCU No. 1, and TCU No. 3 corresponds to NCU No. 2. Then, a log collection instruction including the identifier of TCU No. 2 can be remotely sent to NCU No. 1 through the monitoring platform, and a log collection instruction including the identifier of TCU No. 3 can be sent to NCU No. 2 at the same time. In another case, TCU No. 2 and TCU No. 3 both correspond to NCU No. 1, then a log collection instruction including the identifiers of TCU No. 2 and TCU No. 3 can be remotely sent to NCU No. 1 through the monitoring platform. The number of target TCUs and the corresponding NCUs are not specifically limited here, and it is sufficient to be able to implement the above method.

[0061] Step 102: The NCU collects the logs stored in real time by the target TCU according to the log collection instruction.

[0062] In the method described in this embodiment, the NCU can collect the logs of the TCU in the local area network through the established local area network. As an optional method, when the NCU and all the TCUs corresponding to the NCU form a local area network through lora or zigbee, the NCU collects logs through lora or zigbee, and the way of collecting logs needs to be consistent with the way of forming the local area network. For example, the NCU and all the TCUs corresponding to the NCU form a local area network through lora, then the NCU needs to collect logs through lora. Correspondingly, the NCU and all the TCUs corresponding to the NCU form a local area network through zigbee, then the NCU needs to collect logs through zigbee. Among them, the lora method is more suitable for open places and long-distance transmission, and the zigbee is more suitable for less open places and short-distance transmission. In actual work, it can be freely selected according to needs, and no specific limitation is made here. It is sufficient to implement the method described in this embodiment.

[0063] As another optional method, when the NCU and all TCUs corresponding to the NCU form a local area network through lora and zigbee, when the NCU cannot collect logs through zigbee, it can switch to collecting logs through lora. Correspondingly, when the NCU cannot collect logs through lora, it can also switch to collecting logs through zigbee.

[0064] In the method described in this embodiment, the step of collecting the log of the target TCU can be specifically that the NCU sends a collection request to the target TCU in a point-to-point communication manner based on the established local area network. The target TCU responds to the collection request and feeds the log back to the NCU. The log is stored in real time by the target TCU in the storage partition mounted by the file system of the target TCU. Subsequently, the NCU receives the log and stores it in the storage partition mounted by the file system of the NCU.

[0065] In the method described in this embodiment, the file system of the TCU and the file system of the NCU can both be FAT32 file systems or other file systems. The type of file system is not specifically limited here, and is only used as an example for ease of understanding. The file system can implement the above steps.

[0066] In the method described in this embodiment, the target TCU may feed back logs to the NCU via a text transmission protocol.

[0067] Step 103: The NCU remotely uploads the collected logs.

[0068] In the method described in this embodiment, the NCU can remotely upload the log to the monitoring platform through the MQTT protocol, and the monitoring platform can obtain the historical operation log of the on-site array motor controller to analyze the problem.

[0069] The present embodiment provides a method for remotely obtaining TCU logs through a monitoring platform, which is specifically implemented through a local area network formed by NCU and TCU. In the method described in the present embodiment, when the TCU in the on-site array of the photovoltaic power station is running, the log of the equipment operation can be stored in real time on the storage partition mounted by the file system. When the monitoring platform has debugging or fault location requirements for any TCU, it can issue a collection instruction to the corresponding NCU through the monitoring platform. NCU transfers files with TCU through the local area network, collects logs, and feeds back to the monitoring platform, so that the monitoring platform can realize the function of viewing the logs of any TCU in real time, thereby improving the efficiency of equipment debugging and fault analysis. And compared with the traditional solution of exporting logs for each device on site, the method described in the present embodiment is more efficient and accurate in large-scale photovoltaic tracking bracket systems, reducing a large amount of complicated manual on-site operations, and is more applicable in the scenario of TCU batch log acquisition.

[0070] Embodiment 2: This application discloses another method for collecting logs of photovoltaic tracking bracket system. Figure 2 The method described in this embodiment introduces the whole process of log collection through lora and zigbee.

[0071] Step 201: The first NCU and the first TCU establish a local area network through lora and zigbee.

[0072] Step 202: The monitoring platform sends a log collection instruction of the first TCU to the first NCU.

[0073] Step 203: Check whether the first NCU can perform point-to-point communication with the first TCU via Zigbee. If yes, proceed to step 204. If no, proceed to step 205.

[0074] Step 204: The first NCU collects the log of the first TCU and feeds it back to the monitoring platform.

[0075] Step 205: The first NCU performs point-to-point communication with the first TCU via LoRa. Go to step 204.

[0076] Example 3: This application discloses another method for collecting logs of photovoltaic tracking bracket system. Figure 3a The method described in this embodiment introduces the whole process of batch log collection.

[0077] Step 301: The first NCU, the first TCU and the second TCU form a local area network through lora and zigbee, and the second NCU and the third TCU form a local area network through lora and zigbee.

[0078] Step 302: The monitoring platform sends a log collection instruction of the first TCU and the second TCU to the first NCU, and sends a log collection instruction of the third TCU to the second NCU.

[0079] Step 303: The first NCU performs point-to-point communication with the first TCU and the second TCU through the local area network to obtain logs of the first TCU and the second TCU.

[0080] Step 304: The first NCU feeds back the acquired logs to the monitoring platform.

[0081] Step 305: The second NCU performs point-to-point communication with the third TCU via the local area network to obtain the log of the third TCU.

[0082] Step 306: The second NCU feeds back the acquired logs to the monitoring platform.

[0083] In the method described in this embodiment, a schematic diagram of information transmission of a method for collecting logs of a photovoltaic tracking bracket system is shown in FIG. Figure 3b As shown, the monitoring platform requests the first NCU to collect logs of the first TCU and the second TCU through the MQTT protocol. The first NCU requests the first TCU and the second TCU to collect logs through the local area network, and the first TCU and the second TCU respectively send the logs to the first NCU from the storage partition LOG mounted by their own file systems. The first NCU temporarily stores the collected logs in the storage partition mounted by its own file system, and when the log transmission is completed, it sends the logs to the monitoring platform through the MQTT protocol.
