[0028] 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 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.

[0029] An embodiment of the present application provides a method for upgrading firmware of a power station terminal device, and the method for upgrading firmware of a power station terminal device is applied to a firmware upgrading system of a power station terminal device.

[0030] The power station can be a photovoltaic power station, a wind power station, a hydropower station or other new energy power station.

[0031] like Figure 1 As shown, the power station terminal equipment firmware upgrade system includes a handheld operation terminal 100, a communication gateway 200, a data logger 300 and a terminal device 400 to be upgraded, wherein the handheld operation terminal 100 is connected to the communication gateway 200, the communication gateway 200 is connected to the data logger 300, and each data logger 300 is connected to multiple terminal devices 400 to be upgraded.

[0032] The handheld operation terminal 100 provides a visual interface for the operator, and the operator can perform functional operations on the visual interface, such as: initiating an upgrade (initiating a firmware upgrade of the terminal device to be upgraded), viewing the status (viewing the operating status and upgrade status of the terminal device to be upgraded), and setting downlink parameters (performing system control, active power regulation, reactive power regulation, fault alarm word setting, system setting, power grid code setting, etc. on the terminal device to be upgraded). The handheld operation terminal 100 can also read and display various data information of the terminal device to be upgraded, including operating status information, device attribute information, etc.

[0033] The communication gateway 200 is used to provide a communication port of a communication link, realize the communication connection between the handheld operation terminal 100 and the data logger 300, and complete the data conversion and processing of the communication signal.

[0034] The data logger 300 is used to read various data information of the terminal device to be upgraded, match the protocol information between the firmware and the terminal device to be upgraded, and transfer the matched firmware to the desired terminal device to be upgraded for firmware upgrade.

[0035] The terminal device 400 to be upgraded is a target monitoring terminal, which actively reports the upgrade status during the firmware upgrade process. The terminal device 400 to be upgraded supports at least one device type and supports at least one communication protocol.

[0036] Figure 2 A flowchart of a method for upgrading the firmware of a power station terminal device applied to a handheld operation terminal provided by an embodiment of the present invention is shown in FIG. Figure 2 As shown, the method for upgrading the firmware of a power station terminal device includes steps S10 to S30:

[0037] S10: In response to the operation of the operator initiating the firmware upgrade, the corresponding firmware is matched according to the protocol information and device type of each terminal device to be upgraded under the data logger and a firmware package is generated.

[0038] When the firmware of each terminal device to be upgraded under the data logger is upgraded, the handheld operation terminal 100 is connected to the data logger 300 for communication, and the data logger 300 sends the protocol information and device type of each terminal device to be upgraded to the handheld operation terminal 100; the operator initiates the firmware upgrade by operating the handheld operation terminal 100, and the handheld operation terminal 100 generates a firmware package and sends it to the data logger 300 in response to the operation of the operator initiating the firmware upgrade. Since the protocol information and device type of each terminal device to be upgraded under the data logger may be different, it is necessary to match the corresponding firmware according to the protocol information and device type of each terminal device to be upgraded under the data logger and generate a firmware package.

[0039] S20: Sending the firmware package to the data logger, so that the data logger automatically matches the protocol information and device type of each terminal device to be upgraded under the data logger according to the firmware in the firmware package, and performs firmware upgrade on the terminal device to be upgraded that matches it according to the firmware in the firmware package.

[0040] Since the protocol information and device types of the terminal devices to be upgraded under the data logger may be different, after the data logger 300 receives the firmware package sent by the handheld operation terminal 100, it is necessary to match the protocol information and device type between the firmware and the terminal device to be upgraded. When the protocol information and the device type match, the firmware of the corresponding terminal device 400 to be upgraded can be upgraded.

[0041] S30: receiving and displaying the upgrade status information of each terminal device to be upgraded under the data logger.

[0042] The terminal device 400 to be upgraded actively reports the upgrade status information to the data logger 300 during the firmware upgrade process, and the data logger 300 then forwards the information to the handheld operation terminal 100. The handheld operation terminal 100 receives and displays the upgrade status information of each terminal device to be upgraded under the data logger. Figure 3 FIG. 1 is a flow chart of querying the upgrade status information through the handheld operation terminal 100. Figure 3 As shown, when the terminal device 40 to be upgraded is being upgraded, the handheld operation terminal 100 obtains upgrade progress description information and displays the process progress; when the terminal device 40 to be upgraded is upgraded successfully, the handheld operation terminal 100 displays success information; when the terminal device 40 to be upgraded fails to upgrade, the handheld operation terminal 100 displays failure information.

[0043] In the method for upgrading the firmware of power station terminal equipment provided by the embodiment of the present invention, the handheld operation terminal 100 is connected to the data logger via a wireless proximal end, and the data logger is connected to multiple terminal equipment to be upgraded. After receiving the firmware package, the data logger automatically matches the protocol information and device type of each terminal equipment to be upgraded under the data logger according to the firmware in the firmware package, and performs firmware upgrade on the terminal equipment to be upgraded that matches it according to the firmware in the firmware package, thereby realizing batch upgrade of all terminal equipment to be upgraded under the data logger. This firmware upgrade method greatly reduces the time and labor cost of point-to-point manual terminal upgrades, and improves the efficiency of upgrade and maintenance work.

[0044] In one embodiment, step S10 matches the corresponding firmware according to the protocol information and device type of each terminal device to be upgraded under the data logger, and the generated firmware package is a single attribute firmware package or a combined firmware package.

[0045] Among them, the single-attribute firmware package includes only one firmware, which is a firmware that can upgrade the same device type or a firmware that can upgrade the same functional attribute. When the terminal devices to be upgraded under the data logger are of the same device type, the handheld operation terminal 100 sends one firmware to the data logger 300 to batch upgrade all the terminal devices to be upgraded under the data logger. At this time, the firmware package is a single-attribute firmware package; when the terminal devices to be upgraded under the data logger need to upgrade the same functional attribute, the handheld operation terminal 100 sends one firmware to the data logger 300 to batch upgrade all the terminal devices to be upgraded under the data logger. At this time, the firmware package is a single-attribute firmware package.

[0046] The combined firmware package includes multiple firmware for upgrading at least one device type of terminal device to be upgraded; or, the combined firmware package includes multiple firmware (parameter firmware, patch firmware, etc.) for upgrading at least one functional attribute of the terminal device to be upgraded of the same device type; or, the combined firmware package includes multiple firmware for upgrading the terminal device to be upgraded that supports at least one communication protocol. When each terminal device to be upgraded under the data logger is at least one device type (inverter, photovoltaic storage, PCS, etc.), each type of device requires a firmware upgrade, and the handheld operation terminal 100 needs to send multiple firmwares to the data logger 300 to realize batch upgrade of all terminal devices to be upgraded under the data logger. At this time, the firmware package is a combined firmware package; when each terminal device to be upgraded under the data logger needs to upgrade different functional attributes, each functional attribute requires a firmware upgrade, and the handheld operation terminal 100 needs to send multiple firmwares to the data logger 300 to realize batch upgrade of all terminal devices to be upgraded under the data logger. At this time, the firmware package is a combined firmware package; when each terminal device to be upgraded under the data logger supports different communication protocols, and the terminal devices to be upgraded that support different communication protocols require different firmware upgrades, the handheld operation terminal 100 needs to send multiple firmwares to the data logger 300 to realize batch upgrade of all terminal devices to be upgraded under the data logger. At this time, the firmware package is a combined firmware package.

[0047] The method for upgrading the firmware of the power station terminal equipment provided by the embodiment of the present invention does not limit the device type, quantity and supported communication protocols of each terminal equipment to be upgraded connected to the data logger, has strong compatibility, does not require manual adjustment during upgrading, and further improves the efficiency of the firmware upgrade.

[0048] In one embodiment, the handheld operation terminal 100 is connected to the data logger 300 through the communication gateway 200. Before sending the firmware package to the data logger, the steps include: obtaining the communication gateway software version; if the communication gateway software version is too low, upgrading the gateway firmware.

[0049] Considering that some communication gateway software versions at the power station are relatively old and do not support batch upgrade terminals, it is necessary to upgrade the gateway firmware to the latest version. Figure 4 The figure is a flowchart of the handheld operation terminal sending the firmware package through the communication gateway. Figure 4 As shown, before the handheld operation terminal 100 sends the firmware package to the data logger 300, the communication gateway software version is first obtained and the communication gateway software version is judged. If the communication gateway software version is too low, the gateway firmware is upgraded; otherwise, the firmware information (firmware package) is transmitted to the data logger 300.

[0050] In one embodiment, the method for upgrading the firmware of the power station terminal equipment also includes: obtaining the operation status information and device attribute information of each terminal equipment to be upgraded under the data acquisition device; obtaining the operation status information and device attribute information of the communication gateway; sending a downlink parameter setting instruction to the data acquisition device, so that the data acquisition device performs downlink parameter setting on the corresponding terminal equipment to be upgraded under the data acquisition device according to the downlink parameter setting instruction. Among them, the operation status information of the terminal equipment to be upgraded includes power generation, real-time power, fault alarm information, etc., and the device attribute information of the terminal equipment to be upgraded includes the device type, device model, software version, communication protocol version, etc. of the terminal equipment to be upgraded; the operation status information of the communication gateway includes the signal strength and communication status of the communication gateway, and the device attribute information of the communication gateway includes the device type, device model, software version, communication protocol version, etc. of the communication gateway.

[0051] The power station terminal equipment firmware upgrade method also includes: obtaining the operating status information and device attribute information of the data logger; wherein the operating status information of the data logger includes the number of online, offline, and grid-connected terminals of the subordinate terminals, and the device attribute information of the data logger includes the device type, device model, software version, etc. of the data logger.

[0052] Figure 5 A flowchart of a method for upgrading the firmware of a power station terminal device applied to a data logger provided by an embodiment of the present invention is shown as follows: Figure 5 As shown, the method for upgrading the firmware of a power station terminal device includes steps S110 to S140:

[0053] S110: Sending protocol information and device type of each subordinate terminal device to be upgraded to the handheld operation terminal.

[0054] The data collector 300 establishes communication with multiple terminal devices to be upgraded through a power line carrier (PLC), and obtains the device attribute information and operation status information of each subordinate terminal device to be upgraded in real time, wherein the device attribute information includes protocol information and device type. When the firmware of each terminal device to be upgraded under the data collector is upgraded, the handheld operation terminal 100 is connected to the data collector 300 for communication, and the data collector 300 sends the protocol information and device type of each subordinate terminal device to be upgraded to the handheld operation terminal 100.

[0055] S120: Receive a firmware package generated by the handheld operating terminal matching corresponding firmware according to protocol information and device type of each terminal device to be upgraded.

[0056] The operator initiates the firmware upgrade by operating the handheld operation terminal 100. In response to the operation of the operator initiating the firmware upgrade, the handheld operation terminal 100 generates a firmware package and sends it to the data collector 300. Since the protocol information and device types of each terminal device to be upgraded under the data collector may be different, the handheld operation terminal 100 needs to match the corresponding firmware according to the protocol information and device type of each terminal device to be upgraded under the data collector and generate a firmware package, and finally send the firmware package to the data collector 300.

[0057] S130: Automatically match the protocol information and device type of each terminal device to be upgraded under the data logger according to the firmware in the firmware package, and perform firmware upgrade on the terminal device to be upgraded that matches the firmware in the firmware package.

[0058] Since the protocol information and device types of the terminal devices to be upgraded under the data logger may be different, after the data logger 300 receives the firmware package sent by the handheld operation terminal 100, it is necessary to match the protocol information and device type between the firmware and the terminal device to be upgraded. When the protocol information and the device type match, the firmware of the corresponding terminal device 400 to be upgraded can be upgraded.

[0059] S140: Receive upgrade status information of each subordinate terminal device to be upgraded, and forward it to the handheld operation terminal.

[0060] During the firmware upgrade process, the terminal device 400 to be upgraded actively reports the upgrade status information to the data logger 300, which is then forwarded by the data logger 300 to the handheld operation terminal 100. The operator can view the upgrade status of each terminal device to be upgraded through the handheld operation terminal 100.

[0061] In the method for upgrading the firmware of power station terminal equipment provided by the embodiment of the present invention, the handheld operation terminal 100 is connected to the data logger via a wireless proximal end, and the data logger is connected to multiple terminal equipment to be upgraded. After receiving the firmware package, the data logger automatically matches the protocol information and device type of each terminal equipment to be upgraded under the data logger according to the firmware in the firmware package, and performs firmware upgrade on the terminal equipment to be upgraded that matches it according to the firmware in the firmware package, thereby realizing batch upgrade of all terminal equipment to be upgraded under the data logger. This firmware upgrade method greatly reduces the time and labor cost of point-to-point manual terminal upgrades, and improves the efficiency of upgrade and maintenance work.

[0062] like Figure 6 As shown, in one embodiment, the step S130 further includes:

[0063] S131: Convert the firmware format in the firmware package into a format suitable for the data logger.

[0064] S132: Automatically match the protocol information and device type of each terminal device to be upgraded under the data logger according to the firmware attribute information in the firmware package.

[0065] The firmware in the firmware package is obtained by the handheld operation terminal 100 according to the protocol information and device type matching of each terminal device to be upgraded under the data logger. The attribute information of the firmware includes the protocol information and device type of the device supported by the firmware for upgrading. The data logger 300 obtains the protocol information and device type of each terminal device to be upgraded under it in real time. When the protocol information and device type of the device supported by the firmware for upgrading match the protocol information and device type of the terminal device to be upgraded, it means that the firmware matches the corresponding terminal device to be upgraded.

[0066] S133: Performing firmware upgrade on the terminal device to be upgraded that matches the firmware in the firmware package.

[0067] The data logger 300 transfers the firmware in the firmware package to the terminal device to be upgraded that matches the firmware, and then performs firmware upgrade on the terminal device to be upgraded.

[0068] In one embodiment, the power station terminal device firmware upgrade method further includes: receiving a downlink parameter setting instruction sent by a handheld operation terminal; and performing downlink parameter setting on the corresponding terminal device to be upgraded under the data acquisition device according to the downlink parameter setting instruction. The operator sends a downlink parameter setting instruction through the handheld operation terminal 100, and can perform downlink parameter setting on one or more terminal devices to be upgraded under the data acquisition device, including system control, active power regulation, reactive power regulation, fault alarm word setting, system setting, power grid code setting, etc. for the terminal device to be upgraded.

Figure 7 As shown, the method for upgrading the firmware of a power station terminal device includes steps S210 to S250:

[0070] S210: The data logger sends the protocol information and device type of each subordinate terminal device to be upgraded to the handheld operation terminal.

[0071] S220: Based on the firmware upgrade operation initiated by the operator, the handheld operation terminal matches the corresponding firmware according to the protocol information and device type of each terminal device to be upgraded under the data logger and generates a firmware package.

[0072] S230: The handheld operation terminal sends the firmware package to the data logger, and the data logger automatically matches the protocol information and device type of each terminal device to be upgraded under the data logger according to the firmware in the firmware package, and performs firmware upgrade on the terminal device to be upgraded that matches it according to the firmware in the firmware package.

[0073] S240: The data logger receives the upgrade status information of each subordinate terminal device to be upgraded, and forwards it to the handheld operation terminal.

[0074] S250: The handheld operation terminal receives and displays the upgrade status information of each terminal device to be upgraded under the data logger.

[0075] In the power station terminal equipment firmware upgrade method provided in the embodiment of the present invention, the handheld operation terminal is connected to the data logger via a wireless proximal end, the data logger is connected to multiple terminal devices to be upgraded, after receiving the firmware package, the data logger automatically matches the protocol information and device type of each terminal device to be upgraded under the data logger according to the firmware in the firmware package, and performs firmware upgrade on the terminal devices to be upgraded that match it according to the firmware in the firmware package, thereby realizing batch upgrade of all terminal devices to be upgraded under the data logger.
