[0038] As shown in Figure 3 The SVG remote upgrading method comprises the following steps.

[0039] ​​S410, the monitoring platform and the main controller confirm whether to enter the upgrade step, and after confirming to enter the upgrade step;

[0040] S420, the main controller controls the SVG system to enter the network hanging state;

[0041] S430, the monitoring platform sends the upgrade bit stream data to the main controller in packets;

[0042] S440, the main controller sends the upgrade bit stream data to the application bit stream area of the storage unit of each sub-module;

[0043] S450, the monitoring platform sends the upgrade check data to the main controller, the main controller sends the upgrade check data to each sub-module, the sub-module checks the upgrade bit stream data in the application bit stream area according to the upgrade check data, and judges whether the sub-module passes the check;

[0044] S460, if all the sub-modules pass the check, the sub-module loads the upgrade bit stream data and runs;

[0045] S470, if at least part of the sub-modules fail to pass the check, the sub-module feeds back the upgrade failure information to the monitoring platform through the main controller, and the sub-module loads the backup bit stream data in the backup bit stream area and runs.

[0046] It should be noted that, as shown in Figure 7 The backup bit stream data stored in the backup bit stream area can be understood as a kind of correct backup data, which has sufficient integrity and executability, but the data version is lower.

[0047] In S420, the main controller controls the SVG system to enter the network hanging state, and in the network hanging state, the SVG device is still in the high-voltage closing state, wherein the difference between the network hanging state and the working state is that in the charging process, the energy storage voltage of part of the sub-modules is greater than the charging voltage threshold, and then it can be cut out at any time, while in the working state, the switching of the sub-modules needs to be controlled according to the control instruction, because in the network hanging state, the switching speed of the sub-modules is slow, and the real-time requirement of the control instruction is reduced, therefore, in the network hanging state, the instruction data packet and the upgrade bit stream data packet can be sent alternately, and this process does not affect the network running of the SVG system;

[0048] The SVG remote upgrading method, when the monitoring platform wants to remotely upgrade the sub-modules of the SVG, the monitoring platform can first mutually confirm with the main controller, after confirming to enter the upgrading step, the main controller first controls the sub-modules to enter the network hanging state, without stopping the sub-modules, but also ensures that the sub-modules do not affect the power grid during the upgrading process, the monitoring platform sends the upgrading bit stream data corresponding to each sub-module to the main controller, and then the main controller sends the upgrading bit stream data to each sub-module, wherein the storage unit of the sub-module includes an application bit stream area and a backup bit stream area, the backup bit stream area stores backup bit stream data, and the upgrading bit stream data is only stored in the application bit stream area, after sending the upgrading bit stream data, the main controller sends upgrading check data to each sub-module, the sub-module checks the upgrading bit stream data by using the upgrading check data, and only when all the sub-modules are checked, the sub-module loads the upgrading bit stream data to run, as long as at least part of the sub-modules are not checked, the sub-module loads the backup bit stream data in the backup bit stream area to run, so that the sub-modules can also realize normal operation by using the backup bit stream data when the upgrading fails, the design automatically and efficiently realizes the upgrading of each sub-module, reduces the labor cost, improves the upgrading quality, and meets the demand for improving the operation stability.

[0049] In some embodiments of the application, as shown in Figure 4 The mutual confirmation of the monitoring platform and the main controller in step S410 includes:

[0050] S510, the monitoring platform sends an upgrading request to the main controller;

[0051] S520, the main controller receives the upgrading request, the main controller obtains the running state of the power module and forms an upgrading permission instruction according to the running state;

[0052] S530, when the upgrading permission instruction represents that the upgrading is allowed, the main controller sends the upgrading permission instruction to the monitoring platform and each sub-module respectively to drive the monitoring platform and each sub-module to enter the upgrading step;

[0053] S540, when the upgrading permission instruction represents that the upgrading is prohibited, the main controller sends the upgrading permission instruction to the monitoring platform to prohibit the upgrading.

[0054] When having the upgrade bitstream data with the new version, the monitoring platform sends an upgrade request to the main controller, the main controller can judge whether it is suitable to upgrade according to the running state of the power module, and form an upgrade permission instruction or an upgrade prohibition instruction, when allowing upgrade, the main controller sends the upgrade permission instruction to the monitoring platform and each sub-module, so as to drive the monitoring platform and each sub-module to make upgrade preparation, and enter the upgrade execution step, if not allowing upgrade, the main controller feeds back the upgrade prohibition to the monitoring platform, and can also send the upgrade permission instruction indicating the upgrade prohibition to the sub-module.

[0055] In some embodiments of the application, as shown in Figure 5 The monitoring platform sends the upgrade check data to the main controller in step S450, the main controller sends the upgrade check data to each sub-module, the sub-module checks the upgrade bitstream data in the application bitstream area according to the upgrade check data, and judges whether the sub-module passes the check, and the method comprises the steps of:

[0056] S610, each sub-module receives the upgrade check data;

[0057] S620, each sub-module reads the upgrade bitstream data in the application bitstream area, and checks the upgrade bitstream data by using the upgrade check data;

[0058] S630, when the check passes, the sub-module feeds back check pass marker information to the main controller;

[0059] S640, when the check fails, the sub-module feeds back check failure marker information to the main controller;

[0060] S650, the main controller counts the check pass marker information or the check failure marker information fed back by each sub-module to form upgrade feedback information, wherein the upgrade feedback information is one of upgrade success information and upgrade failure information.

[0061] After the upgrade bitstream data is sent out, the monitoring platform sends a bitstream data end instruction to the main controller; after receiving the bitstream data end instruction, the main controller sends a bitstream end instruction to the sub-module, and the control unit in the sub-module stops writing data to the storage unit.

[0062] The upgrade check data can be a CRC check value, and whether the CRC check value and the CRC check code of the upgrade bitstream data cached in the application bitstream area are consistent is checked by using the CRC algorithm, if consistent, the check passes, the sub-module feeds back check pass marker information to the main controller, if inconsistent, the sub-module feeds back check failure marker information to the main controller, and the main controller counts the information fed back by all sub-modules, thereby forming the upgrade feedback information.

[0063] In some embodiments of the present application, if all the sub-modules pass the check, the sub-modules load the upgrade bitstream data and run in the following steps:

[0064] The main controller sends the upgrade success information to the monitoring platform to cancel the upgrade permission instruction.

[0065] The main controller sends the upgrade success information to each sub-module, and the sub-modules load the upgrade bitstream data and run.

[0066] In some embodiments of the present application, if at least part of the sub-modules fail the check, the sub-modules feed back the upgrade failure information to the monitoring platform through the main controller, and the sub-modules load the backup bitstream data in the backup bitstream area and run in the following steps:

[0067] The main controller sends the upgrade failure information to the monitoring platform to cancel the upgrade permission instruction.

[0068] The main controller sends the upgrade failure information to each sub-module, and the sub-modules load the backup bitstream data and run.

[0069] Regardless of whether the upgrade is successful or failed, the main controller sends the upgrade success information or the upgrade failure information to the monitoring platform to cancel the upgrade permission instruction formed in step S520, so as to prevent the upgrade permission instruction from remaining in the monitoring platform and causing control disorder after the upgrade is completed.

[0070] In some embodiments of the present application, as shown in FIG. 5B, the main controller sends the upgrade bitstream data to the application bitstream area of the storage unit of each sub-module in the following steps: Figure 6

[0071] The main controller alternately sends instruction data packets and upgrade bitstream data packets to the sub-modules, wherein the instruction data packets include instruction data, and the upgrade bitstream data packets include upgrade bitstream data.

[0072] Since the main controller still needs to control each sub-module during the upgrade, the sub-modules need to receive both the instruction data for controlling the operation of the sub-modules and the upgrade bitstream data, and therefore, the instruction data packets and the upgrade bitstream data packets are alternately sent during the data transmission, so that the sub-modules can execute the control required by the main controller and complete the upgrade.

[0073] ​In some embodiments of the present application, the instruction data packet further comprises a first packet header, the first packet header and the instruction data are sequentially arranged, the upgrade bitstream data packet further comprises a second packet header, the second packet header and the upgrade bitstream data are sequentially arranged, in one unit transmission period, the main controller only transmits one instruction data packet or one upgrade bitstream data packet, in multiple continuous unit transmission periods, the instruction data packet and the upgrade bitstream data packet are alternately transmitted, the instruction data is separated from the front upgrade bitstream data by the first packet header, and the upgrade bitstream data is separated from the front instruction data by the second packet header.

[0074] The instruction data of the instruction data packet and the upgrade bitstream data of the upgrade bitstream data packet are distinguished by the first packet header and the second packet header, the main controller alternately transmits the instruction data packet and the upgrade bitstream data packet in each unit transmission period, so that the instruction data packet and the upgrade bitstream data packet are distinguished and transmitted in a reasonable and orderly manner.
