[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0034] At present, magnetic levitation molecular pumps can be divided into the following types:

[0035] (1) According to different diameters, it is divided into three types: DN200, DN250 and DN320;

[0036] (2) According to different pumping speeds, it is divided into 1400L / s, 2300L / s, 3000L / s, and 3300L / s;

[0037] (3) According to the different speeds, it is divided into 350Hz, 400Hz, 450Hz, 460Hz, 500Hz, and 550Hz;

[0038] (4) According to different functions, it can be divided into with / without water valve, with / without heating belt;

[0039] (5) According to different materials, it can be divided into ordinary type, corrosion-resistant type, etc.

[0040] (6) According to the different structures, it can be divided into integrated type and split type.

[0041] In order to develop a universal controller compatible with mainstream pump models, a controller based on a multi-core architecture is used to realize the functions of automatic model identification and automatic execution of corresponding programs, thereby creating a magnetic levitation molecular pump controller compatible with multiple models, which is conducive to product popularization, controller update and maintenance, and improves user experience. This function together constitutes an important part of the magnetic levitation molecular pump control system, providing strong support for high vacuum environment applications in the high-tech field.

[0042] At present, for magnetic levitation molecular pump controllers, the corresponding programs for different models of magnetic levitation molecular pumps are different, which is specifically reflected in different program control parameters and program control schemes. In the hardware implementation of the controller board, an additional program burning module needs to be reserved, which increases the size and structural complexity of the board. For the mass production of major models of magnetic levitation molecular pumps, a large production cost will be introduced. In addition, in terms of program burning and performance verification, the entire controller needs to be functionally tested, which will also introduce a large labor cost.

[0043] For the EtherCAT function of the magnetic levitation molecular pump controller, the EtherCAT board is currently used for program function output. This places higher requirements on the internal structure assembly of the magnetic levitation molecular pump controller, and connecting the main controller board and the EtherCAT board through pin headers or cables will lead to unstable communication data transmission.

[0044] With the advancement of technology and changes in market demand, magnetic levitation molecular pumps are developing in a more diversified direction, and the needs of different industries and manufacturers are gradually becoming common problems. This requires us to improve the controller structure and enhance the controller performance to be compatible with more possible functions. In this context, the molecular pump controller with a single core architecture used in the current system is difficult to meet the dual high standards of extensiveness and high performance in actual application scenarios. In order to meet this challenge, it is urgent to explore and develop more efficient and flexible molecular pump controllers to ensure that magnetic levitation molecular pumps can adapt to the rapid development and diversified needs of the future market.

[0045] The embodiment of the present invention provides a magnetic levitation molecular pump control architecture based on a multi-core controller, including a controller based on a multi-core architecture, wherein the controller chip adopts an AM6442 processor.

[0046] The AM6442 processor is a processor chip based on the ARM architecture. Figure 1 As shown, it integrates seven cores, including two 1GHz ARM Cortex-A53 cores, four 800MHz ARM Cortex-R5F cores, and one 400MHz ARM Cortex-M4F core.

[0047] Specifically, the ARM Cortex-A53 core can provide powerful computing power for complex application processing and can easily run advanced operating systems such as Linux. It is suitable for application scenarios that require large amounts of data processing and complex algorithms, and can process the computing tasks of applications, thereby realizing functions such as artificial intelligence and big data processing.

[0048] Specifically, the ARM Cortex-R5F core has a computing power of up to 6400 million instructions per second (DMIPS) and has low-latency interrupt technology, which can meet tasks with high real-time requirements, such as high-precision motor control loops.

[0049] Specifically, the ARM Cortex-M4F core is used to implement functional safety features and can independently handle safety-related tasks to ensure the stability and reliability of the system.

[0050] The model information of the magnetic levitation molecular pump is read through the ARM Cortex-M4F, and then the ARM Cortex-A53 core starts and calls the corresponding ARM Cortex-R5F program to achieve compatibility with different models of magnetic levitation molecular pumps.

[0051] At the same time, through the collaboration of ARM Cortex-A53 and ARM Cortex-R5F, EtherCAT single-board integration is achieved, making the AM6442 processor compatible with EtherCAT functions.

[0052] Through the collaboration of ARM Cortex-A53 and ARM Cortex-R5F, EtherCAT single-board integration is achieved, and the EtherCAT function is integrated into the main control board.

[0053] In some optional implementations, under the current architecture, there are multiple Cortex-R5F cores, and each Cortex-R5F core runs completely independently. Therefore, the control programs of four main types of magnetic levitation molecular pumps can be pre-burned into these four cores respectively, and each Cortex-R5F core carries a program of a different magnetic levitation molecular pump.

[0054] In some optional embodiments, the ARM Cortex-R5F transmits tasks with a computational workload greater than a preset computational workload threshold through inter-core communication, and the ARM Cortex-A53 processes functional modules with core resource occupancy higher than a preset occupancy threshold to improve the computing performance of the molecular pump controller.

[0055] In some optional embodiments, the processor also integrates two Programmable Real-Time Units (PRUs) to manage the Ethernet Time-Sensitive Networking (Ethernet TSN (Time-Sensitive Networking)) industrial communication subsystem of the device. It supports IEEE1588 Precision Time Protocol (PTP) up to 1GB TSN, and also supports multiple industrial Ethernet protocols such as EtherCAT, Profinet, Ethernet / IP, etc., which can achieve deterministic network communication and meet the application scenarios with strict requirements for real-time communication such as industrial automation.

[0056] The AM6442 processor is used as the controller chip, and its ARMCortex-A53 application core running under the Linux operating system is used to process the computing tasks of the application program, thereby realizing functions such as artificial intelligence and big data processing. The Cortex-R5F real-time core is used to realize program control and data processing. At the same time, the Cortex-M4F core is used to assist the Cortex-R5F core in completing EtherCAT, Profinet, Ethernet / IP and other tasks, and preprocessing some peripheral interfaces.

[0057] Under the current architecture, each Cortex-R5F core runs completely independently. Therefore, the control programs of the four main types of magnetic levitation molecular pumps can be pre-burned into these four cores respectively. The molecular pump model information is read through the Cortex-M4F, and then the ARM Cortex-A53 core starts and calls the corresponding Cortex-R5F program to run the corresponding program, so as to achieve compatibility with more molecular pump models. At the same time, the single-board integration of EtherCAT is realized through the collaboration of ARM Cortex-A53 and ARM Cortex-R5F. ARM Cortex-R5F transfers tasks with a computing amount greater than the preset computing amount threshold through inter-core communication to ARM Cortex-A53 for processing, and ARM Cortex-A53 processes functional modules with core resource occupancy higher than the preset occupancy threshold.

[0058] The magnetic levitation controller is built based on the AM6442 chip. The embodiment of the present invention builds DDR large-capacity memory, large-capacity eMMC storage, and PCIe to fully meet the high-performance and multi-functional output needs of the controller. At the same time, the AM6442 chip is compatible with the EtherCAT function. By rebuilding the control board, EtherCAT is integrated into the main control board, which provides a novel and effective solution for simplifying the controller board structure and improving the controller compatibility. At the same time, the multi-core controller is compatible with the control requirements of various types of molecular pumps, and has high scalability and broad application prospects.

[0059] The magnetic levitation molecular pump control architecture based on a multi-core controller provided in this embodiment builds a magnetic levitation molecular pump controller based on the AM6442 chip, reads the model of the magnetic levitation molecular pump through the ARM Cortex-M4F to call the corresponding ARMCortex-R5F program, thereby being compatible with the model of the magnetic levitation molecular pump and improving the compatibility of the magnetic levitation molecular pump controller.

[0064] Step S202, determining the target program to be called according to the read model information of the magnetic levitation molecular pump, so as to be compatible with different models of magnetic levitation molecular pumps.
