[0011] The online upgrade of the master node NC device includes the following steps:

[0012] S11, using the Ethernet of the master node NC device to send the master node NC device online upgrade instruction to the current device;

[0013] S12, the master node NC device enters the online upgrade function, uses the Ethernet of the device to receive the upgrade solidification file of the master node NC device, and then receives the data through the ZYNQ chip on the device, puts it in the DDR memory for cache, and determines whether it is the upgrade solidification file of the NC device.

Combining the FC-AE-1553 bus with ZYNQ can achieve efficient and reliable multi-node online upgrades.

[0030] like Figure 1 As shown in the figure, the system specifically includes a master node network controller NC device and multiple slave node network terminal NT devices. The master node is responsible for collecting the data to be solidified, managing and controlling the entire online upgrade process.

[0034] Based on the above system structure, this embodiment also provides a multi-node ZYNQ online upgrade method based on FC-AE-1553 bus, including online upgrade of master node NC device and online upgrade of slave node NT device;

[0035] The online upgrade of the master node NC device includes the following steps:

[0036] S11, using the Ethernet of the master node NC device to send the master node NC device online upgrade instruction (including the ID of the NC device and the byte size of the solidified file) to the local device;

[0037] S12, the master node NC device enters the online upgrade function, uses the Ethernet of the device to receive the upgrade solidification file of the master node NC device, and then receives the data through the ZYNQ chip on the device, puts it in the DDR memory for cache, and determines whether it is the upgrade solidification file of the NC device. If so, the file is loaded into the FLASH storage chip of the device to complete the online upgrade of the master node NC device itself;

[0038] Online upgrade of the slave node NT device includes the following steps:

[0039] S21, using the Ethernet of the master node NC device to send an online upgrade instruction of the slave node NT device to the device;

[0040] S22, the master node NC device parses the slave node NT device online upgrade instruction (including the ID of the NT device and the byte size of the fixed file), and then sends the online upgrade instruction to the corresponding slave node NT device through the FC-AE-1553 bus, and the slave node NT device enters the online upgrade function;

[0041] S23, using the Ethernet of the master node NC device to receive the upgrade and solidification file of the slave node NT device, and then receiving the data through the ZYNQ chip on the device, caching it in the DDR memory, and judging whether it is the upgrade and solidification file of the slave node NT device. If it is, encoding the file into multiple 64KB data packets, storing them in the DDR memory on the master node NC device, and then sending the data to the slave node NT device through the FC-AE-1553 bus;

[0042] S24, the slave node NT device receives the data packet through the FC-AE-1553 bus, receives the data through the ZYNQ chip on the device, and caches it in the DDR memory to determine whether it is the upgrade solidification file of the slave node NT device. If so, it is loaded into the FLASH storage chip on the device to complete the online upgrade of the slave node NT device itself, and the online upgrade success flag of the device is set to 1;

[0043] S25. After sending the solidified file data, the master node NC device will query the online upgrade status through the FC-AE-1553 bus. If all are successful, it will exit the online upgrade, otherwise it will restart the online upgrade process, that is, if the online upgrade success flag of the corresponding slave node NT device is not set to 1, then repeat steps S21 to S24 for the slave node NT device that failed to upgrade for a second time.
