[0024] Embodiment One

[0025] Figure 1A flowchart of a distributed photovoltaic data collection method is provided for Embodiment One of the present application. The present application can be applied to the collection of photovoltaic data. The method is executed by a master module in a distributed photovoltaic data collection device. The distributed photovoltaic data collection device includes a wired transmission communication module, an ad hoc wireless communication module, a cloud communication module, and a master module. Each distributed photovoltaic data collection device is connected to a corresponding photovoltaic device. The master module is an electronic device with data processing capability. As shown in FIG. 6A, the method includes the following steps. Figure 1

[0026] S110, obtaining a first working mode and a second working mode of the distributed photovoltaic data collection device.

[0027] In the present application, each distributed photovoltaic data collection device can correspond to a photovoltaic station. The photovoltaic station is provided with a photovoltaic device. The distributed photovoltaic data collection device is used to upload photovoltaic data of the photovoltaic device to the cloud through a domain master station. The domain master station is a distributed photovoltaic data collection device that adopts a certain working mode.

[0028] In the present application, the working mode of the distributed photovoltaic data collection device has two modes, i.e., a first working mode and a second working mode, which constitute four combinations. The first working mode and the second working mode can be pre-set in the distributed photovoltaic data collection device. The first working mode reflects whether the distributed photovoltaic data collection device communicates with the cloud server. The second working mode reflects whether the distributed photovoltaic data collection device communicates with other groups of distributed photovoltaic data collection devices.

[0029] Specifically, each distributed photovoltaic data collection device can be arranged at different locations. Some distributed photovoltaic data collection devices are densely distributed, and some are sparsely distributed. The hardware structure of the distributed photovoltaic data collection devices at different locations can be the same, and the working mode can be different. The devices in a group (the second working mode of the devices in the group reflects that the distributed photovoltaic data collection devices do not communicate with other groups of distributed photovoltaic data collection devices) can send the collected photovoltaic data to the group master station. The group master station can then send the collected photovoltaic data to the domain master station. The first working mode of the domain master station reflects the need to communicate with the cloud server.

[0030] ​The present scheme sets different working modes for the distributed photovoltaic data collection devices at different positions. The distributed photovoltaic data collection devices with high distribution density can be set as a group, and their second working mode reflects that they do not communicate with the distributed photovoltaic data collection devices of other groups. The distributed photovoltaic data collection devices with long distance can be set as different groups or even different domains, so that when the photovoltaic data is collected subsequently, the distributed photovoltaic data collection devices with short distance (located in the same group or the same domain) can use wired communication or ad hoc wireless communication, and then the photovoltaic data of the entire domain is transmitted to the cloud through the cloud communication module (such as a 4G communication module) of the domain master station for subsequent cloud uploading.

[0031] The present scheme sets that the distributed photovoltaic data collection devices in each domain transmit the collected photovoltaic data to the cloud through the domain master station, so as to uniformly collect and manage the photovoltaic data, and also avoids waste of resources.

[0032] Specifically, after the present distributed photovoltaic data collection device is activated, the steps of automatically triggering to read the pre-configured first working mode and second working mode can be triggered.

[0033] S120, determining a sending object according to the first working mode and the second working mode.

[0034] The sending object is the sending object of all the photovoltaic data received by the present distributed photovoltaic data collection device, and the photovoltaic data received by the present distributed photovoltaic data collection device includes the photovoltaic data of the photovoltaic device connected to the present distributed photovoltaic data collection device.

[0035] Specifically, each distributed photovoltaic data collection device can receive the photovoltaic data of the connected photovoltaic device. For a certain distributed photovoltaic data collection device, it may only receive the photovoltaic data of the photovoltaic device connected to itself, or it may receive the photovoltaic data of the photovoltaic device connected to itself and the photovoltaic data sent by other distributed photovoltaic data collection devices. For all the received photovoltaic data, the sending object needs to be determined so that the photovoltaic data at different positions can be collected to the cloud.

[0036] For example, when the sending object is determined, if it is determined according to the first working mode and the second working mode that the present device is a group device, the sending object is determined as a group master station, and then the specific group master station information is determined according to the pre-configured domain node link table.

[0037] S130, transmitting the photovoltaic data to the sending object through a target communication module; the target communication module is a wired transmission communication module, an ad hoc wireless communication module or a cloud communication module.

[0038] Specifically, if the sending object is a cloud server, the target communication module is determined to be a cloud communication module, and then the photovoltaic data is sent to the cloud server through the cloud communication module. If the sending object is a domain master station, the target communication module is determined to be a wired transmission communication module or an ad hoc wireless communication module, and then the photovoltaic data is sent to the cloud server through the wired transmission communication module or the ad hoc wireless communication module.

[0039] The technical scheme of the embodiment of the present application is that the distributed photovoltaic data acquisition method is executed by a master module in a distributed photovoltaic data acquisition device, the distributed photovoltaic data acquisition device comprising a wired transmission communication module, an ad hoc wireless communication module, a cloud communication module, and a master module; each distributed photovoltaic data acquisition device is connected with a corresponding photovoltaic device; the method comprises: obtaining a first working mode and a second working mode of the distributed photovoltaic data acquisition device pre-configured; the first working mode reflects whether the distributed photovoltaic data acquisition device communicates with a cloud server; the second working mode reflects whether the distributed photovoltaic data acquisition device communicates with other groups of distributed photovoltaic data acquisition devices; determining a sending object according to the first working mode and the second working mode; the sending object is the sending object of all photovoltaic data received by the distributed photovoltaic data acquisition device; the photovoltaic data received by the distributed photovoltaic data acquisition device includes photovoltaic data of the photovoltaic device connected with the distributed photovoltaic data acquisition device; sending the photovoltaic data to the sending object through a target communication module; the target communication module is a wired transmission communication module, an ad hoc wireless communication module, or a cloud communication module. The technical scheme sets different working modes for different distributed photovoltaic data acquisition devices, determines a sending object and a communication module suitable for the device, and improves the scene adaptability.

[0040] Embodiment two

[0041] Figure 2A flow chart of a distributed photovoltaic data collection method provided in Embodiment Two of the present application is optimized based on the above-mentioned embodiment. The method is executed by a master module in a distributed photovoltaic data collection device, which includes a wired transmission communication module, an ad hoc wireless communication module, a cloud communication module, and a master module. Each distributed photovoltaic data collection device is connected to a corresponding photovoltaic device. Illustratively, the wired transmission communication module can be an RS485 interface and a message conversion unit; the message conversion unit can be a max3485 module; the ad hoc wireless communication module can be a lora mesh (long-range radio mesh network) module, and the cloud communication module can be a 4GHz wireless module; the max3485 module is used to convert the message data transmitted by the RS485 interface into ttl (Time To Live, Time To Live) message feedback to the control module (RS485 interface is a kind of communication interface); the lora mesh module is used for message interaction through lora mesh. The 4GHz wireless module is used for communication through 4G wireless network.

[0042] In the embodiment of the present application, the sending object is optionally a group master station, a domain master station, or a cloud server. The group master station and the domain master station are both the present distributed photovoltaic data collection device configured with a certain working mode, the group master station is used to receive photovoltaic data collected by each device in the group, the domain master station is used to receive photovoltaic data of each group sent by each group master station in the domain, and the cloud server is used to receive photovoltaic data collected by each device in the domain sent by the domain master station.

[0043] As shown in Figure 2 The method of the embodiment of the present application specifically includes the following steps:

[0044] S210, a first working mode and a second working mode of the present distributed photovoltaic data collection device are obtained.

[0045] S220, if the first working mode is a domain master station mode and the second working mode is a group boundary mode, the sending object is determined to be a cloud server.

[0046] The domain master station mode reflects that the photovoltaic data in the domain is sent to the cloud server through the present distributed photovoltaic data collection device, and the non-domain master station mode reflects that the photovoltaic data in the domain is not sent to the cloud server through the present distributed photovoltaic data collection device. The group boundary mode reflects that the photovoltaic data in the group is sent to the present distributed photovoltaic data collection device, and the non-group boundary mode reflects that the photovoltaic data received by the present distributed photovoltaic data collection device needs to be sent to the group master station.

[0047] It should be noted that in the embodiments of the present application, each distributed photovoltaic data acquisition device plays different roles according to different working modes. In a domain, at least one group is provided, at least one intra-group device is provided in each group, the intra-group device sends the photovoltaic data of the photovoltaic device connected to the device to the group master station, the group master station sends the photovoltaic data in the group (including the photovoltaic data of the photovoltaic device connected to the group master station itself) to the domain master station, and the domain master station sends the photovoltaic data in the domain (including the photovoltaic data of the photovoltaic device connected to the domain master station itself) to the cloud server.

[0048] S230, receiving photovoltaic data sent by other devices in the group and photovoltaic data sent by each group master station.

[0049] Specifically, if the first working mode is the domain master station mode and the second working mode is the group boundary mode, the distributed photovoltaic data acquisition device is determined as the domain master station and the group master station. Therefore, after receiving the photovoltaic data sent by other devices in the group and the photovoltaic data sent by each group master station, the uploading of the photovoltaic data in the domain is performed.

[0050] In the embodiments of the present application, before receiving the photovoltaic data sent by other devices in the group and the photovoltaic data sent by each group master station, the method further includes: sending a domain node link table to the group master station, so that the group master station forwards the domain node link table to the devices in each group, so that each device in the domain determines the group master station information and the domain master station information according to the domain node link table.

[0051] The present scheme is thus set, so that each device (i.e. the distributed photovoltaic data acquisition device) can know the specific information of the sending object, ensuring the accuracy of photovoltaic data transmission.

[0052] S240, determining that the target communication module is a cloud communication module.

[0053] S250, sending the photovoltaic data to the cloud server through the cloud communication module.

[0054] Specifically, since communication with the cloud server is required, the target communication module is determined as the cloud communication module, and the photovoltaic data is sent to the cloud server through the cloud communication module.

[0055] Figure 3 The flowchart of another distributed photovoltaic data acquisition method provided in Embodiment Two of the present application is shown in Figure 3 as shown, comprising:

[0056] S310, obtaining the first working mode and the second working mode of the distributed photovoltaic data acquisition device pre-configured.

[0057] S320, if the first working mode is the domain master station mode and the second working mode is the non-group boundary mode, determining that the sending object is the cloud server.

[0058] Specifically, if the first working mode is the domain master station mode and the second working mode is the non-group boundary mode, it is determined that the distributed photovoltaic data acquisition device is the domain master station and is not the group master station, and it can be determined that the sending object is the cloud server.

[0059] S330, receiving photovoltaic data sent by each group master station.

[0060] Specifically, since the distributed photovoltaic data acquisition device is the domain master station and is not the group master station, the photovoltaic data of the photovoltaic device connected to the distributed photovoltaic data acquisition device can be sent to the group master station of the group on one hand, and then all the photovoltaic data in the group sent by the group master station is received; on the other hand, the photovoltaic data of the photovoltaic device connected to the distributed photovoltaic data acquisition device can be temporarily not processed, and after receiving the photovoltaic data of other devices in the group sent by the group master station of the group, the photovoltaic data of the photovoltaic device connected to the distributed photovoltaic data acquisition device is integrated into the photovoltaic data of the group.

[0061] S340, determining that the target communication module is the cloud communication module.

[0062] S350, sending the photovoltaic data to the cloud server through the cloud communication module.

[0063] Figure 4 The flowchart of another distributed photovoltaic data acquisition method provided by Embodiment Two of the present application is shown in FIG. 4, which includes: Figure 4

[0064] S410, obtaining the first working mode and the second working mode of the distributed photovoltaic data acquisition device pre-configured.

[0065] S420, if the first working mode is the non-domain master station mode and the second working mode is the non-group boundary mode, determining that the sending object is the group master station.

[0066] Specifically, if the first working mode is the non-domain master station mode and the second working mode is the non-group boundary mode, it is determined that the distributed photovoltaic data acquisition device is an in-group device, and the photovoltaic data of the photovoltaic device connected to the distributed photovoltaic data acquisition device needs to be sent to the group master station.

[0067] S430, determining that the target communication module is the wired transmission communication module or the ad hoc wireless communication module according to the pre-configured in-group data transmission mode.

[0068] ​Optionally, the wired transmission communication module comprises four RS485 interfaces, each of which is connected with a max3485 module; and the ad hoc wireless communication module can be a lora mesh module.

[0069] Specifically, if the preconfigured data transmission mode in the group is wired transmission, the target communication module is determined as a wired transmission communication module. If the preconfigured data transmission mode in the group is wireless transmission, the target communication module is determined as an ad hoc wireless communication module. The data transmission mode in each group is only one kind. This scheme is set in this way, so that only one kind of communication mode is involved when group communication is performed, greatly reducing the communication complexity and improving the communication stability.

[0070] S440, sending photovoltaic data to the group master station through the target communication module.

[0071] Specifically, if the target communication module is determined as a wired transmission communication module, the photovoltaic data is sent to the group master station through the RS485 interface. If the target communication module is determined as an ad hoc wireless communication module, the photovoltaic data is sent to the group master station through the ad hoc wireless communication module (lora mesh module).

[0072] Figure 5 A flowchart of another distributed photovoltaic data acquisition method provided in Embodiment Two of the application is shown in FIG. 6, which comprises the following steps: Figure 5

[0073] S510, obtaining a preconfigured first working mode and a preconfigured second working mode of the distributed photovoltaic data acquisition device.

[0074] S520, if the first working mode is a non-domain master station mode and the second working mode is a group boundary mode, determining the sending object as a domain master station.

[0075] Specifically, if the first working mode is a non-domain master station mode and the second working mode is a group boundary mode, the distributed photovoltaic data acquisition device is determined as a group master station, which needs to receive the photovoltaic data sent by each device in the group and send the photovoltaic data to the domain master station.

[0076] S530, receiving the photovoltaic data sent by each device in the group.

[0077] S540, determining the target communication module as a wired transmission communication module or an ad hoc wireless communication module according to the preconfigured domain transmission mode.

[0078] ​Specifically, if the pre-configured data transmission mode in the group is wired transmission, the target communication module is determined as a wired transmission communication module. If the pre-configured data transmission mode in the group is wireless transmission, the target communication module is determined as an ad hoc wireless communication module.

[0079] For example, if the group master station is close to the domain master station, the intra-domain transmission mode can be wired transmission, otherwise, the intra-domain transmission mode can be wireless transmission.

[0080] S550, sending photovoltaic data to the domain master station through the target communication module.

[0081] In the embodiment of the application, four working modes are set for each distributed photovoltaic data acquisition device, so that each distributed photovoltaic data acquisition device determines the sending object of the photovoltaic data according to the working mode, and the photovoltaic data is uploaded to the cloud through the two levels of group and domain. In the case of unified photovoltaic data uploading, the scene adaptability is improved, so that each additional photovoltaic data acquisition point can use the same distributed photovoltaic data acquisition device (the configured working mode can be different) to collect and upload photovoltaic data. Using the same distributed photovoltaic data acquisition device has the effect of reducing cost compared to using different photovoltaic data acquisition devices.

[0082] For example, there are four RS485 interfaces, which are 485 channel #1, 485 channel #2, 485 channel #3 and 485 channel #4. 485 channel #1 and 485 channel #2 are connected to two cloud platforms respectively, 485 channel #3 is used for intra-group data transmission, and 485 channel #4 is used for inter-group data transmission. When the distributed photovoltaic data acquisition device is used as a domain master station and a group boundary mode, the distributed photovoltaic data acquisition device reads the configuration after starting, and then detects whether there is a cloud request in 485 channel #1. If there is a request, the detection of 485 channel #2 will be checked until there is no data transmission, and then the slave station (each distributed photovoltaic data acquisition device in the domain) will forward the request message. When the slave station replies to the distributed photovoltaic data acquisition device, the reply message of the slave station will be directly forwarded to 485 channel #1. This setting can avoid communication conflicts of the distributed photovoltaic data acquisition device when two platforms are connected.
