DETAILED DESCRIPTION

[0030] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0031] See also Figure 1, the embodiment of the utility model provides a photovoltaic gateway device supporting online topology upgrade, including a power supply circuit 17, a processor 11, a downlink communication circuit 12, an uplink communication circuit 13, a downlink expansion circuit 15 and a storage circuit 14;

[0032] The downlink communication circuit 12 receives external data and transmits it to the processor 11;

[0033] The processor 11 receives and processes the data transmitted by the downlink communication circuit 12, and transmits it to the uplink communication circuit 13 or the storage circuit 14; the processor 11 pre-processes the data transmitted by the downlink communication circuit 12 according to the predetermined algorithms and rules, including configuring the communication network parameters and managing the communication protocol of the external device, and performs simple data analysis and processing. According to the configuration, the downloaded data can be stored and forwarded, and the processed data and analysis results can be reported separately;

[0034] The uplink communication circuit 13 transmits data transmitted by the processor 11 to the outside;

[0035] The storage circuit 14 receives data transmitted by the processor 11 and saves or deletes the data transmitted by the processor 11 according to the instruction sent by the processor 11;

[0036] The downlink communication circuit 12 includes a first wireless circuit 122; the downlink communication circuit 12 receives external data through the first wireless circuit 122;

[0037] The downlink expansion circuit 15 is connected to the processor 11, and the downlink expansion circuit 15 is provided with a downlink communication interface;

[0038] The uplink communication circuit 13 includes a second wireless circuit 132 ; the second wireless circuit 131 is provided with a user identification interface 1321 , which is a SIM interface or an eSIM interface. The uplink communication circuit 13 transmits data to the outside through the second wireless circuit 132 , and realizes the routing function through the uplink communication circuit 13 .

[0039] This embodiment provides a downlink expansion circuit 15 to expand the downlink communication on the basis of the original downlink communication circuit 12, so that the photovoltaic gateway device 10 can receive data in multiple modes, improve the real-time and effectiveness of data collection, and provide a user identification interface 1321 to expand the uplink communication, which can be configured and expanded as needed, which is flexible and convenient. At the same time, uplink communication and downlink communication use non-interfering channels to transmit data, which reduces interference between the server and the device, or between devices during data transmission, further ensures data transmission efficiency, and thus improves the upgrade efficiency of the photovoltaic gateway device 10 and improves the upgrade success rate. In addition, the utility model can be externally upgraded on the basis of the original equipment, has strong applicability and reduces system complexity, improves the stability and reliability of the photovoltaic gateway device 10, avoids equipment replacement, and thus reduces material costs and construction costs.

[0040] See also Figure 2 When the photovoltaic gateway device 10, i.e., the photovoltaic gateway device supporting online topology upgrade, needs to be upgraded, the cloud server 20 is first logged in, and the photovoltaic gateway device 10 most suitable for online upgrade is found based on a comprehensive evaluation of parameters such as device storage space, device operating status, and device network signal. The photovoltaic gateway device 10 has established a connection with the cloud server 20 through the uplink communication circuit 13. The cloud server 20 sends an upgrade request or upgrade instruction to the photovoltaic gateway device 10. The upgrade request or upgrade instruction is transmitted through the MQTT transmission protocol. After the photovoltaic gateway device 10 receives the upgrade request or upgrade instruction, the processor 11 parses and verifies it. After the parsing and verification is successful, the download address of the upgrade package is obtained according to the upgrade request or upgrade instruction and is connected to the download address. The photovoltaic gateway device 10 establishes a network connection with the address and downloads the upgrade package. Usually, a TCP network connection is established between the photovoltaic gateway device 10 and the download address of the upgrade package to ensure stable and reliable transmission of large file data. The upgrade package is transmitted to the processor 11 via the downlink communication circuit 12 or the external downlink communication circuit by the downlink expansion circuit 15 and processed by the processor 11. If the parsing verification is passed, it is transmitted to the storage circuit 14 and the photovoltaic gateway device 10 is upgraded, and the upgrade package is backed up in the storage circuit 14. Alternatively, the upgrade package is transmitted to the storage circuit 14 via the downlink communication circuit 12 and backed up by the processor 11. If the parsing verification is passed, it is transmitted to the storage circuit 14 and the photovoltaic gateway device 10 is backed up. If the parsing verification is passed, it is transmitted to the storage circuit 14 and the photovoltaic gateway device 10 is backed up. If the upgrade parsing verification fails, the upgrade package is deleted and downloaded again or the upgrade is exited.

[0041] Secondly, the successfully upgraded photovoltaic gateway device 10 first turns off the hotspot search function of the uplink communication circuit 13 and turns on its own hotspot. When the hotspot is turned on successfully, the network connection function is started, waiting for other photovoltaic gateway devices 10 to search and connect. When other photovoltaic gateway devices 10 to be upgraded are searching, the successfully upgraded photovoltaic gateway device 10 will collect and screen, screen out the photovoltaic gateway devices 10 to be upgraded whose hotspot signals meet the connection conditions, and try to connect one by one. After the connection is successful, a network connection is established between the photovoltaic gateway device 10 to be upgraded and the photovoltaic gateway device 10 that has been successfully upgraded.

[0042] After the connection is successful, the photovoltaic gateway device 10 to be upgraded is the client photovoltaic gateway device 10, and the photovoltaic gateway device 10 that has successfully upgraded is the server photovoltaic gateway device 10. The client photovoltaic gateway device 10 transmits its basic information including the version number of the current photovoltaic gateway device, device storage space, hotspot connection signal status, device operation status and other data to the server photovoltaic gateway device 10 through the uplink communication circuit 13. The server photovoltaic gateway device 10 receives the data of the client photovoltaic gateway device 10 through the downlink communication circuit 12 or through the downlink expansion circuit 15 through the external downlink communication circuit and transmits it to the processor 11. In order to avoid repeated upgrades or continuous upgrade interruptions due to poor signals during the upgrade process, the processor 11 of the server photovoltaic gateway device 10 verifies and judges the information data of the client photovoltaic gateway device 10, and kicks out the client photovoltaic gateway device 10 that does not meet the upgrade conditions, such as: already upgraded, poor signal, device ID number or other information verification failed, etc. After the verification is successful, the server-side photovoltaic gateway device 10 initiates an upgrade request or upgrade instruction to the client-side photovoltaic gateway device 10 that meets the upgrade conditions. After the client-side photovoltaic gateway device 10 receives the upgrade request or upgrade instruction, the processor 11 parses and verifies it. After the parsing and verification is successful, the client-side photovoltaic gateway device 10 downloads the upgrade package backed up in the storage circuit 14 from the server-side photovoltaic gateway device 10. The upgrade package is successively transmitted to the client-side photovoltaic gateway device 10 through the uplink communication circuit 13 of the server-side photovoltaic gateway device 10, the downlink communication circuit 12 of the client-side photovoltaic gateway device 10, or through the external downlink communication circuit through the downlink expansion circuit 15. The processor 11 of the photovoltaic gateway device 10 is used for processing. If the parsing verification is passed, it is transmitted to the storage circuit 14 of the client photovoltaic gateway device 10 and the client photovoltaic gateway device 10 is upgraded, and the upgrade package is backed up in the storage circuit 14 of the client photovoltaic gateway device 10, or the upgrade package is transmitted to the storage circuit 14 of the client photovoltaic gateway device 10 through the downlink communication circuit 12 or through the external downlink communication circuit through the downlink expansion circuit 15, and then the processor 11 performs parsing verification. If the parsing verification is passed, it is transmitted to the storage circuit 14 and the photovoltaic gateway device 10. If the upgrade parsing verification fails, the upgrade package is deleted, downloaded again or the upgrade is exited. Usually, if the upgrade parsing verification fails, the upgrade is downloaded again three times. If all of them fail, the server-side photovoltaic gateway device 10 will send an exit upgrade process instruction to the client photovoltaic gateway device 10, and the server-side photovoltaic gateway device 10 will record and file the client photovoltaic gateway device 10 that failed to upgrade, so as to try to upgrade it again later;

[0043] After the upgrade is successful, the client photovoltaic gateway device 10 sends an upgrade completion signal to the server photovoltaic gateway device 10. The server photovoltaic gateway device 10 sends an instruction to automatically disconnect the network connection and hotspot connection to the successfully upgraded client photovoltaic gateway device 10 according to the upgrade completion signal. The successfully upgraded client photovoltaic gateway device 10 disconnects the network connection with the server photovoltaic gateway device 10 and closes the hotspot, and continues to provide topology upgrade services for other photovoltaic gateway devices 10 to be upgraded until all upgradeable photovoltaic gateway devices 10 are upgraded. Online upgrade of photovoltaic gateway devices can be achieved in the case of poor network signals, greatly saving manual operation costs and time costs.

At the same time, it can ensure that the downlink channel and the uplink channel do not interfere with each other, that is, the channel for receiving external data and the channel for transmitting data to the outside do not interfere with each other, thereby reducing the interference between the server and the device, or between the devices during data transmission, and improving the upgrade efficiency.
