aiming at the problems in the prior art, in order to make up the disadvantage of poor reliability of on-line upgrading transmission of firmware, the photovoltaic cell uses a backup upgrading technology, the whole firmware is received by the photovoltaic cell for integrity verification, and backup upgrading is carried out after no abnormity is verified so as to ensure the upgrading stability. Therefore, the problem of firmware upgrading of the distributed photovoltaic energy storage system is solved, and the introduction of the online firmware upgrading and backup technology is very important.
The schematic frame diagram of the invention is shown in fig. 2, the photovoltaic system firmware is issued to the remote module from the background through WiFi or 4G, after the module receives the data, the whole merged firmware data is issued to the inverter and then transmitted to the main board, after the firmware is issued, the BMS performs integrity check on the whole merged firmware and identifies the number and type of the firmware in the merged firmware, and then copies or issues each firmware.
The specific upgrade flow is shown in fig. 3, and includes the following steps:
step 1: the battery system mainboard interacts with the inverter, and the whole merged firmware is written into a mainboard backup flash; the mainboard judges the number of the firmware of the merged firmware according to the rule of the merged firmware and takes out the firmware attribute of each firmware, and the rule of the merged firmware is shown in table 1:
TABLE 1
And 2, step: the mainboard judges whether the firmware of the mainboard exists or not and judges whether the firmware versions are consistent or not according to the attributes of the firmware acquired in the step 1; if the mainboard firmware exists and the version numbers are inconsistent, copying the mainboard firmware to the MCUflash; after the MCU judges the integrity of the firmware, the MCU waits for the opportunity to copy and update; the update conditions are as follows:
1. and (3) restarting the system: after the system is restarted, automatically identifying whether firmware needs to be updated or not by the IAP, copying data of the backup MCUflash to an execution area and verifying the integrity of the firmware if the firmware needs to be updated, and jumping to an APP to finish data updating if the firmware is completely verified; otherwise, data copying is carried out again;
2. under the condition that the system is in a standby state, the system can restart by itself to complete firmware updating;
3. the system can receive an inverter restart instruction for firmware update.
And step 3: the method comprises the steps that a master board detects whether slave board firmware exists and whether the slave board firmware is consistent with the current slave board version number, if yes and the versions are inconsistent, the master board initiates an upgrading process and issues the slave board firmware to a slave board MCU backup flash through a CAN bus; the slave plate carries out integrity check on the firmware of the backup flash, and if the integrity check of the firmware is passed, the slave plate resets to copy the firmware;
and 4, step 4: and (4) continuously detecting whether the firmware versions are completely updated according to the step (3).
In summary, compared with the prior art, the technical scheme of the invention has at least the following beneficial effects:
1. from the aspect of battery operation stability, the upgrading data can be received under the condition of APP operation without entering a BootLoader, the battery system can be ensured to be always in a controlled state in the data receiving process, and the time of staying in the BootLoader is short only under the condition of resetting and copying data;
2. receiving data under the APP operation condition from a data link receiving layer, if data interaction is abnormal, enabling the battery system to still normally operate, and waiting for initiating an upgrading task next time;
3. from the background operation layer, the firmware merging technology supports that a plurality of firmware are merged together at one time and are issued to the battery system, and the inside of the battery system is processed, so that the phenomenon that the background initiates an upgrading task for many times is reduced.
