[0028] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0029] In the existing technology, industrial computers usually adopt modular design due to their complex application scenarios and high environmental adaptability requirements in order to save costs and adapt to different on-site requirements.

[0030] However, the industrial computers currently on the market that use modular design only support single-board control of the main control board, and the sub-board does not have core processing capabilities. When an abnormality occurs on the main control board, it is very easy for the smart factory or automated production line to be suspended due to the abnormality of the industrial computer motherboard.

[0031] Based on this, the present application proposes a dual-core industrial computer and its control method, so that the sub-board is connected to the COME Type 6 interface of the main control board through the COME Type 6 interface, and the sub-board core card is connected to the main control board through the sub-board interface board to form a dual-core industrial computer, forming a redundant design to avoid the problem of suspension of smart factories or automated production lines due to abnormalities of the industrial computer motherboard.

[0032] Please refer to Figure 1 In an exemplary embodiment, a dual-core industrial computer is provided, including: a main control board 101, a sub-board interface board 102 and a sub-board core daughter card 103.

[0033] The secondary board includes a secondary board interface board 102 and a secondary board core daughter card 103 .

[0034] Specifically, the secondary board is connected to the COME Type 6 interface of the main control board 101 via the COME Type 6 interface. The secondary board includes a secondary board interface board 102 and a secondary board core daughter card 103 . The secondary board core daughter card 103 is connected to the main control board 101 via the secondary board interface board 102 .

[0035] In this way, a dual-core industrial computer is formed by the sub-board core daughter card 103 connected to the sub-board, forming a redundant design, thereby avoiding the problem of suspension of the smart factory or automated production line due to abnormality of the industrial computer mainboard.

[0036] The main control board 101 further includes: at least one Ethernet port 201 , multiple USB interfaces 203 , at least one MiniPCIE interface 202 and at least one DDR slot 204 .

[0037] Specifically, the sub-board interface board 102 further includes: multiple Ethernet ports 201 , multiple COM interfaces 205 , multiple USB interfaces 203 , at least one MiniPCIE interface 202 , at least one DDR slot 204 and multiple audio interfaces 206 .

[0038] Specifically, at least one DDR slot 204 of the secondary board core daughter card 103 includes a SODIMM-DDR4 memory slot, and the secondary board core daughter card 103 is connected to the main control board 101 by being plugged into the SODIMM-DDR4 memory slot.

[0039] Here, the capacity of SODIMM-DDR4 memory bars usually ranges from 4GB to 64GB. Users can choose the appropriate memory capacity according to the needs of the application scenario. Common DDR4 memory speeds include 2133MT / s, 2400MT / s, 2666MT / s and 3200MT / s. The increase in data transmission rate can significantly increase memory bandwidth, thereby improving the overall performance of the system. Working voltage: The standard working voltage of DDR4 memory bars is 1.2V. Compared with 1.5V and 1.35V of DDR3 memory, DDR4 memory can effectively reduce energy consumption and is suitable for use in mobile devices and high-density servers. The standard DDR4 SODIMM module is about 67.6mm long, 30mm wide and 1.18mm thick. This design allows it to fit into small spaces. SODIMM-DDR4 memory bars usually use multi-layer packaging technology. The number and arrangement of chips will affect the performance and stability of the memory. In addition, ECC (Error Correcting Code) memory needs to be used with a motherboard and chipset that supports ECC to give full play to its error correction capabilities. Common chipsets include Intel's C series and AMD's EPYC series. These chipsets support ECC memory to enhance data reliability. SODIMM-DDR4 memory sticks are widely used in various computing devices that require high reliability and high performance, including industrial control, power applications, telecommunications equipment, medical equipment, rail transportation, power equipment and other high-demand terminal equipment.

[0040] This application utilizes the scheme of connecting the daughter card of the SODIMM-DDR4 memory slot to the main control board 101, and realizes the rapid replacement and upgrade of the hardware module through a standardized interface (such as the SODIMM-DDR4 slot). The functions of the main control board 101 and the daughter board can be designed independently to improve flexibility. The SODIMM-DDR4 slot has a high pin density and can provide more signal connection channels. The use of ready-made standard interfaces reduces the design cost of custom connectors. The SODIMM slot is industrially verified and has high stability and durability. The use of plug-in method facilitates maintenance and replacement.

[0041] In addition, the present application adopts a standard interface to reduce the development and production costs of non-standard connectors.

[0042] In one embodiment, the secondary board core daughter card 103 is a SAM RK3568 ARM architecture.

[0043] In one embodiment, the main control board 101 is an Intel X86 main control board 101 .

[0044] In one embodiment, the secondary board interface board 102 and the secondary board core daughter card 103 are electrically connected via a detachable structure.

[0045] In one embodiment, at least one Ethernet port 201 is a 10 Mbps, 100 Mbps or 1000 Mbps adaptive industrial Ethernet interface.

[0046] As an example, see Figure 2 In an exemplary embodiment, a dual-core industrial computer is provided, including: a main control board 101, a sub-board interface board 102 and a sub-board core daughter card 103, wherein the main control board 101 includes an Ethernet port 201, a USB interface 203, a MiniPCIE interface 202, and a DDR slot 204, and the sub-board interface board 102 includes an Ethernet port 201, a COM interface 205, a USB interface 203, a MiniPCIE interface 202, a DDR slot 204 and an audio interface 206.

[0047] The main control board 101 is an Intel X86-based main control board 101, supports the COME Type 6 standard, and provides a system main control function.

[0048] Here, the features of Intel X86 main control board 101 mainly include powerful computing power, rich software support, multiple operating system support and wide compatibility. Its architecture features and performance are as follows: X86 architecture is a complex instruction set computer (CISC) architecture, which was launched by Intel and widely used in the field of personal computers and servers. Industrial control motherboards with X86 architecture usually use Intel or AMD processors, with powerful computing power and rich software support. X86 processors usually have multi-core architectures, suitable for high-load computing tasks, and can handle complex tasks and multi-tasking. The power consumption of X86 industrial control motherboards is generally around 40W or above, and the CPU must be equipped with a fan. Long-term work may cause the motherboard temperature to rise, affecting performance and life. Therefore, X86 main control board 101 needs to consider good heat dissipation measures when designing and using it. X86 development boards usually have multiple interfaces, such as USB, HDMI, Ethernet, etc., which are convenient for connecting external devices. In addition, X86 architecture supports multiple operating systems, such as Windows, Linux, etc., providing developers with more choices. Due to the universality of X86 architecture, developers can easily find a lot of reference materials and community support when encountering problems.

[0049] As an example, one Ethernet port 201, two USB interfaces 203, one MiniPCIE interface 202, one DDR slot 204, etc. may be provided.

[0050] The slave board interface board 102 supports the COME Type 6 standard and is interconnected with the main control board 101 via a COME Type 6 interface.

[0051] Here, the main features of the COME Type 6 standard include its high-performance interface support, applicability to a variety of application scenarios, and high flexibility of modular design. The COME Type 6 standard is a version of the COM Express standard that supports a variety of advanced interfaces such as PCI Express Gen 4 and USB 4, which enables it to meet current and future technology trends. In addition, COME Type 6 also supports interfaces such as general SPI and MIPI-CSI, further expanding its functionality and application range. The application scenarios of the COME Type 6 standard are very wide and suitable for a variety of fields. The basic COME Type 6 computing module supports designs up to 75 watts and is suitable for applications such as medical, gaming, test and measurement, and industrial automation. The compact COME Type 6 module is suitable for single-chip x86 solutions with a power range between 5 and 20 watts, suitable for medium and entry-level applications such as transportation, robotics, edge servers, industrial control, and HMI in the medical field. The COME Type 6 standard is designed with a variety of modern display outputs in mind, suitable for fields such as medical, gaming, test and measurement, and industrial automation. Its modular design provides a high degree of flexibility and supports different processor and interface configurations to meet the needs of various specific applications.

[0052] As an example, the sub-board interface board 102 can provide 1-2 Ethernet ports 201, 2-6 COM interfaces 205, 10 USB interfaces 203, 1 MiniPCIE interface 202, 1 DDR slot 204, 2 sets of audio interfaces 206, and the like.

[0053] The secondary board core daughter card 103 is a secondary board core daughter card 103 based on the RK3568 ARM architecture, and can be plugged into the secondary board DDR slot.

[0054] Here, the RK3568 core board is a domestically produced industrial core board under Chuanglong Technology. It is designed based on the Rockchip RK3568J / RK3568B2 processor, quad-core ARM Cortex-A55, and the main frequency of each core is up to 1.8GHz / 2.0GHz. All components of the RK3568 core board, such as CPU, ROM, RAM, power supply, crystal oscillator, connector, etc., adopt domestic industrial-grade solutions, with a localization rate of 100%.

The core board has been verified by professional PCB Layout and high and low temperature tests. It is stable and reliable and can meet various industrial application environments.

[0055] The main control board 101 is connected to the sub-board via a COME Type 6 interface. The sub-board supports multiple interfaces and provides a removable sub-board core daughter card 103 .

[0056] Exemplarily, the secondary board core daughter card 103 may be a SAM RK3568 ARM architecture control board, which is plugged into the secondary board via a SODIMM-DDR4 memory slot.

[0057] Here, the SAM RK3568 ARM architecture control board has the characteristics of high performance, low power consumption and rich interfaces.

It integrates a high-performance Mali-G52 GPU and supports multiple graphics API standards, such as OpenGL ES 1.1 / 2.0 / 3.2, OpenCL 2.0, and Vulkan 1.112. In addition, RK3568 also has a built-in RKNN NPU, which provides 1Tops computing power and supports the application of multiple AI algorithms. The Mali-G52 GPU built into RK3568 supports multiple graphics API standards, including OpenGL ES, Vulkan, and OpenCL, which are suitable for high-end games and complex 3D graphics applications.

The control board of RK3568 is suitable for a variety of application scenarios, including smart home, industrial control, IoT terminals, etc. In smart home, it can be used for smart speakers, smart cameras, smart door locks and other devices; in industrial control, it can meet the requirements of real-time and stability, and is suitable for automation equipment and industrial monitoring systems; in the field of IoT, it supports edge computing and a variety of wireless communication methods, and is suitable for smart gateways, home automation controllers and other devices. The dual-core industrial computer proposed in this application connects the sub-board to the COME Type6 interface of the main control board through the COME Type6 interface, and the sub-board core sub-card is connected to the main control board through the sub-board interface board to form a dual-core industrial computer, forming a redundant design to avoid the problem of suspension of smart factories or automated production lines due to abnormalities in the industrial computer motherboard.

[0058] Based on the same inventive concept, an embodiment of the present application further provides a control method for a dual-core industrial computer used to control the dual-core industrial computer involved above.

[0059] Please refer to Figure 3 In an exemplary embodiment, a control method for a dual-core industrial computer is provided, comprising:

[0060] S101, controlling the core daughter card of the secondary board in the secondary board to receive the target signal of the main control board.

[0061] S102: When the core daughter card of the secondary board in the secondary board cannot receive the target signal of the main control board, it is determined that the main control board is shut down.

[0062] S103, controlling the core daughter card of the sub-board in the sub-board to call the core of the main control board to control the system of the dual-core industrial computer.

[0063] As an example, the present application provides an embodiment, in which the entire system is usually controlled by the main control board; the core CPU of the main control board can be shut down through BIOS, and the core daughter card of the secondary board works at this time; the core daughter card of the secondary board is removable and can be not installed when dual control is not required, and the main and secondary boards always use the core of the main control board.

[0064] Here, you can control the shutdown or startup of the main control board through BIOS. You need to use the BIOS setup interface of the motherboard or through BIOS-related functions. The specific steps depend on the type of motherboard and function support. As an example, BIOS usually provides a scheduled startup function. The following are the setup steps: Enter the BIOS interface, and you can press the specified key (usually `Del`, `F2`, `F12`, `ESC`, etc., depending on the motherboard model) when restarting the motherboard; find the power management option, enter the BIOS menu, navigate to Power Management, ACPI Configuration or similar options; Enable the startup function, find the following options in the menu, and configure them as needed: Wake on LAN (WOL) wakes up the device through the LAN signal, RTC Wake-Up (Real-Time Clock), set a scheduled startup, such as automatic startup at 8:00 am every day, PowerOn by Alarm, allowing the device to be woken up by date or time; Save the settings and exit, press `F10` to save the changes and exit, and the system will automatically start at the set time.

[0065] As an example, you can use the following steps to control the automatic shutdown of the main control board through BIOS: BIOS itself usually does not provide a scheduled shutdown function, but it can be implemented in conjunction with the operating system or external hardware. Set a scheduled shutdown task in the operating system (such as through Windows Task Scheduler or Linux's `shutdown` command); cooperate with a UPS (uninterruptible power supply) system to automatically trigger a shutdown when the main power is interrupted.

[0066] As an example, you can also use external signals to control the main control board to turn on / off. Some main control boards support controlling their on / off status through hardware interfaces or signals. This method is often used in industrial control or remote management.

[0067] As an example, it can also be triggered by hardware. The power switch pin on the motherboard (usually marked as `PWR_SW`) can be controlled to turn on or off by short-circuiting; short-pressing the switch trigger pin will cause the motherboard to turn on; long-pressing can force a shutdown.

[0068] As an example, it can also be controlled through GPIO (general purpose input and output). For example, some embedded main control boards support power control through GPIO. You need to refer to the main control board manual to configure related pins to trigger power on or off.

[0069] As an example, it can also be triggered by software, for example, using IPMI (Intelligent Platform Management Interface) or similar remote management tools to control the power on / off state of the main control board, connected to the BMC (Baseboard Management Controller) of the motherboard, and sending power control commands remotely (such as `ipmitool power on / off`). Through the above methods, the power on and off control of the main control board can be flexibly realized, whether it is triggered by timing settings or external signals.

[0070] It should be understood that, although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders.

[0071] The dual-core industrial computer and control method thereof proposed in the present application enable the secondary board to be connected to the COME Type 6 interface of the main control board via the COME Type 6 interface, and the secondary board core daughter card is connected to the main control board via the secondary board interface board to form a dual-core industrial computer, forming a redundant design, thereby avoiding the problem of suspension of smart factories or automated production lines due to abnormalities of the industrial computer mainboard.

[0072] Each step in the control method of the dual-core industrial computer can be implemented in whole or in part by software, hardware, or a combination thereof. Each of the above modules can be embedded in or independent of a processor in a computer device in the form of hardware, or can be stored in a memory in a computer device in the form of software, so that the processor can call and execute operations corresponding to each of the above modules.
