[0067] The FPGA module sends the pre-processed raw data of the high-voltage inverter to the multi-core DSP for algorithm processing;

[0068] The DDR particles cache the data processed by the algorithm.

[0069] In the specific implementation, Figure 6 As shown, Figure 6 This is a general calculation board principle block diagram of the high-voltage inverter control device based on the single-mode optical fiber bus of the utility model, see Figure 6 , the PCIE bridge communicates with the multi-core DSP through the FPGA; the multi-core DSP completes the Local bus communication between the general computing boards through the FPGA; the FPGA completes the parallel pre-processing of the original data of the high-voltage inverter and sends it to the multi-core DSP for algorithm processing, and the DDR particles perform data caching; the industrial computer CPU accesses the general computing board through the PCIE bridge.

[0071] It should be understood that by accessing each PCIE device, when the general computing board fails, the hot standby general computing board is immediately started to achieve seamless connection of the equipment on the process line, and real-time tracking and control can be achieved.

[0072] In a specific implementation, the number of general computing boards can usually be set to two. Of course, other numbers can also be set according to actual application scenarios, and this embodiment does not impose any restrictions on this. Taking two boards as an example, the two are backup for each other, which means that when computing board 0 is working, computing board 1 is ready to replace computing board 0 when computing board 0 fails. That is, after general computing board 0 fails, it will immediately and seamlessly switch to general computing board 1 for calculation. The optical module network switch board and general computing boards 0 and 1 are all plugged in through the PCIE slot on the industrial computer motherboard and are all inside the industrial computer.

[0073] Correspondingly, various types of equipment on the current process line are connected to the industrial computer via the single-mode optical fiber bus.

[0074] It should be noted that various types of equipment on the industrial process line are connected to the network switching board on the industrial computer through a fiber optic bus to achieve control of multiple sets of equipment.

[0076] Accordingly, a high-voltage inverter control system based on a single-mode optical fiber bus is proposed, which includes a high-voltage inverter control device based on a single-mode optical fiber bus. The high-voltage inverter control system based on the single-mode optical fiber bus also includes a host computer; Figure 7 As shown, Figure 7 This is a functional module diagram of the first embodiment of the high-voltage inverter control system based on the single-mode optical fiber bus of the utility model, see Figure 7 ,

[0077] The host computer 20 plays back the current waveform and the voltage waveform, and reconstructs the state of each node of the high-voltage inverter.

[0078] It should be noted that by replaying the current and voltage waveforms on the host computer, the status of each node of the high-voltage inverter can be reconstructed in the host computer according to the actual operation; when equipment fails on the process line, the fault analysis software on the host computer can analyze and judge based on local data, quickly find the fault point, and eliminate the equipment failure.

At the same time, hot backup is achieved through the redundancy of the computing board, and multi-type system control data exchange is achieved through the single-mode optical fiber bus board.

[0080] Correspondingly, such as Figure 8 As shown, Figure 8 This is a schematic diagram of the control logic of the high-voltage inverter control system based on the single-mode optical fiber bus of the utility model, see Figure 8 In the process management, there are general computing board task 0, general computing board task 1, optical fiber bus routing task 2 and real-time storage task 3, etc. The high-voltage inverter control system based on the single-mode optical fiber bus is a real-time operating system, and correspondingly there are various subsystems, such as a file system, for storage and file management, and correspondingly, there are various interfaces, such as a human-machine interface, for equipment and job management.

[0081] The industrial computer runs a real-time operating system and stores the data of the equipment on the process line in real time on the local hard disk; the current and voltage waveforms are replayed on the host computer, and the status of each node of the high-voltage inverter is reconstructed on the host computer; each PCIE device is accessed, and when the general computing board fails, the hot standby general computing board is immediately started to achieve seamless connection of the equipment on the process line and real-time tracking and control; when the equipment on the process line fails, the fault analysis software on the host computer can analyze and judge based on the local data, quickly find the fault point, and eliminate the equipment failure; according to the requirements of the process line, the process control software automatically and collaboratively controls the equipment on the process line.

[0082] This embodiment proposes a high-voltage inverter control system based on a single-mode optical fiber bus, which includes a high-voltage inverter control device based on a single-mode optical fiber bus. By replaying the current waveform and the voltage waveform by the host computer and reconstructing the state of each node of the high-voltage inverter, the original cause of the abnormal state can be immediately analyzed, and there is no need to shut down the machine to troubleshoot the fault, thus avoiding losses in the corresponding process section, saving time for fault handling, ensuring the stability of the high-voltage inverter operation, and improving the speed and efficiency of high-voltage inverter management and control.
