In power systems, high-pressure energy storage is an important requirement of power systems, such as high-pressure energy storage valve systems. Taking a high-pressure energy storage valve system as an example, a plurality of power modules can be arranged in the high-pressure energy storage valve system, and are limited by the anti-interference application environment of high-voltage electromagnetism of a high-pressure valve tower, and the power modules are used for taking electricity at high pressure on site. Meanwhile, due to the high-electric-pressure electromagnetic working environment, the power module usually adopts a single FPGA working mode, and programs are directly burned through an FPGA debugging port when firmware is first burned in a factory or upgraded by valve control outside the factory.

In the application process of the power module of the high-pressure energy storage valve system, the situation that the control unit of the power module needs to be upgraded due to field defects or other requirements is inevitable. When a control unit of a power module is upgraded in the traditional technology, a high-pressure valve tower is generally firstly put into maintenance, an independent working power supply is carried by a worker to a scene where the power module is located, and the power module is electrified on site through the carried independent working power supply module; completing software upgrading after power on; and restarting the power module after upgrading is completed.

Furthermore, a low-voltage standby power supply can be added for the control unit at the same time, the high-voltage energy-taking power supply is used for charging the low-voltage standby power supply, the power supply is switched to the control unit which is used as the power module in the upgrading process, the upgrading process of the power module can be completed under the condition that the power module is not required to carry an external power supply in the power module, and the safety of the upgrading process of the power module is ensured.

In some embodiments, the upgrade package may be carried in the upgrade instruction, and the upgrade package is obtained while the upgrade instruction is obtained, and the upgrade package is analyzed to obtain the upgrade data. In other embodiments, the upgrade package may be requested to be downloaded to the upgrade package download address based on the upgrade instructions after the upgrade instructions are obtained. The upgrade package download address may be pre-stored in the device executing the upgrade process, for example, the controller 1111 shown in fig. 3 and 4, the first processor 1112 shown in fig. 5 and 6, and the second processor 60 shown in fig. 7 and 8.

If the power supply of the low-voltage standby power supply is normal, whether the high-voltage energy-taking power supply is normal or not is further judged, and whether the power module is in a maintenance state or not is judged. If the high-voltage energy-taking power supply is abnormal or the power module is not in the overhaul state, it indicates that power supply abnormality may exist or a risk of upgrading in a high-voltage high-electromagnetic environment may exist, and therefore upgrading cannot be performed, so that the network upgrading control device is replied to reject upgrading information, and the reject upgrading information may include information that the reason for rejecting upgrading is that the high-voltage energy-taking power supply is abnormal or the power module is not in the overhaul state.

If the high-voltage energy-taking power supply is normal and the power module is in the maintenance state, the upgrading process is determined to be executed, so that the low-voltage standby power supply is switched to supply power to the control unit, the FPGA is informed to prepare software upgrading, and meanwhile, the upgrading readiness of the network upgrading control equipment is replied.

And after receiving the information of the ready upgrading, the network upgrading control equipment sends an upgrading packet to be carried out to the control unit. After receiving the upgrade package, the control unit may perform an upgrade process based on the upgrade package.

After the upgrade of the upgrade package is completed, whether the device is automatically restarted after the upgrade is completed is monitored. If the automatic restart is not carried out, whether the information that the maintenance personnel confirm the manual start equipment is received or not is confirmed, if the information is not received, the FPGA is informed again to prepare software upgrading, and the upgrading process is executed again.

If the equipment is automatically restarted after the upgrading is finished, or the information that maintenance personnel confirm that the equipment is manually started is received although the equipment is not automatically restarted, the upgrading is confirmed to be finished, and the upgraded program data are stored.

And after the program data is stored, whether the initialization is correct after restarting is confirmed, if the initialization is incorrect, the FPGA is informed again to prepare software upgrading, and the upgrading process is executed again.

If the initialization is correct, whether the power supply of the high-voltage energy-taking power supply is normal is further confirmed, if the power supply is normal, the high-voltage energy-taking power supply is switched to the power supply of the high-voltage energy-taking power supply, the maintenance state is quitted, and therefore the upgrading process is finished.
