[0039] Based on this, embodiments of this application provide an industrial programmable logic control motherboard, referring to... Figure 1 , Figure 1 This is a schematic diagram of the structural modules of the industrial programmable logic control motherboard of this application.
[0040] In this embodiment, the programmable logic motherboard includes:
[0041] The core processing module 10; the bottom connection module 20 is arranged overlapping the core processing module 10, and the bottom connection module 20 is connected to the core processing module 10 through a first slot; the interface module 30 and the power module 40 are arranged vertically to the bottom connection module 20, the interface module 30 is connected to the bottom connection module 20 through a high-speed connector, and the power module 40 is connected to the bottom connection module 20 through an electronic connector.
[0042] according to Figure 1As can be seen, this embodiment adopts a modular design for the loading and connection of devices, that is, a multi-board design. The functions of each device installed on the industrial programmable logic control motherboard are modularly integrated, thereby reducing the coupling between devices installed on the module and devices installed on other modules. This allows a module to be replaced or upgraded without affecting other modules, thereby reducing the impact of modifying one device on other devices. This can effectively improve the convenience of subsequent maintenance and upgrade of the industrial programmable logic control motherboard, and effectively reduce the limitation of overall performance improvement caused by high coupling between devices.
[0043] In this embodiment, by modularizing the devices used for core data processing to form a core processing module 10; modularizing the devices related to the baseboard to form a bottom connection module 20; and modularizing the devices related to the interface to form an interface module 30, in order to avoid the problem that the control motherboard needs to be installed in a large planar space due to the horizontal direction of the control motherboard, this embodiment proposes to utilize the vertical space of the control motherboard in the industrial computer.
[0044] Specifically, the core processing module 10 and the bottom connection module 20 are connected in an overlapping manner through the first slot, namely COM-ESLOT; the bottom connection module 20 and the interface module 30 are connected vertically through a high-speed connector; and the bottom connection module 20 and the power module 40 are connected vertically through an electronic connector, namely a 24-pin header and socket. This improves the space utilization of the industrial control computer, so that the overall volume of the industrial control computer after installation does not exceed one liter.
[0045] In this embodiment, the power module 40 is a DC voltage of 24V±20%, which can support undervoltage protection and overvoltage protection.
[0046] Specifically, refer to Figure 2 As shown, the core processing module 10 includes an embedded processor, a low-power double data rate 4X memory, and an embedded onboard memory; the low-power double data rate 4X memory and the embedded onboard memory are respectively bidirectionally connected to the embedded processor.
[0047] In this embodiment, the core processing module 10 includes an embedded processor, such as an Intel Elkhart Lake platform processor, low-power double data rate 4X memory, and embedded onboard memory, such as EMMC onboard memory. These devices are characterized by small size and low power consumption, which can reduce the power consumption required during operation while reducing the motherboard area of the industrial programmable logic control motherboard.
[0048] It should be noted that the core board in this embodiment, which is equipped with an embedded processor, low-power double data rate 4X memory and embedded onboard memory, adopts a COM-E design and uses the Mini Module size, which is only 84mm*55mm in size, further reducing the horizontal area required.
[0049] In one embodiment, the underlying connection module 20 includes a non-volatile static random access memory and a fan interface; the fan interface is connected to a cooling fan.
[0050] In this embodiment, the non-volatile static random access memory has a storage capacity of 512K and establishes an SPI (Serial Peripheral Interface) connection with the baseboard on the underlying connection module 20. This enables the rapid saving of critical data when the industrial control computer loses power, and also enables the rapid recovery of data when the industrial control computer regains power, thereby improving the operational safety of the industrial control computer.
[0051] Furthermore, by connecting a cooling fan, the heat dissipation requirements of the components can be met, further improving the operational safety of the industrial control computer.
[0052] In one embodiment, the industrial programmable logic control motherboard further includes a microcontroller and a transformer; the microcontroller establishes a bidirectional connection with the transformer, and the microcontroller is connected to the underlying connection module 20 through an electronic connector.
[0053] As described above, the electronic connector in this embodiment is a 24-pin header and socket. After the baseboard in the bottom connection module 20 establishes a bidirectional connection with the microcontroller through the 24-pin header and socket, it can transmit the output baseboard serial port signal to the microcontroller for conversion to obtain an RS485 signal. The 100Mbps Ethernet port signal and the RS485 signal share the same position of the 24-pin header and socket for transmission.
[0054] It should be noted that the underlying connection module 20 can control different LEDs in the power module 40 to represent the operating status of the industrial programmable logic control motherboard by sending GPIO signals to the power module 40. Simultaneously, it can control relays on the underlying connection module 20 via GPIO signals to select between outputting 100Mbps Ethernet signals and RS485 signals, thereby achieving physical isolation, avoiding signal interference, and meeting transmission requirements.
[0055] The relay is controlled by GPIO signals. The UART (Universal Asynchronous Receiver / Transmitter) interface, microcontroller, transformer, and RS485 signal ports are bidirectionally connected. The 100Mbps Ethernet port signal and RS485 signal are selected and output by the relay.
[0056] In one embodiment, the interface module 30 includes an input / output hub board.
[0057] In one embodiment, the industrial programmable logic control motherboard includes a first gigabit Ethernet network interface controller chip and a second gigabit Ethernet network interface controller chip; the first gigabit Ethernet network interface controller establishes a communication connection with the input / output hub board through a first signal converter, and the second gigabit Ethernet network interface controller chip establishes a communication connection with the input / output hub board through a second signal converter; the first gigabit Ethernet network interface controller chip and the second gigabit Ethernet network interface controller chip are respectively provided with RJ45 network ports.
[0058] Specifically, both the first and second gigabit Ethernet network interface controller chips are Intel I210-AT GbE network card chips, which connect to the PCIE (PCI Express, high-speed serial computer bus standard) interface on the input / output hub board. They can communicate with external devices through two RJ45 network ports. Based on the characteristics of the Intel I210-AT GbE network card chip, the communication transmission speed with external devices can reach up to 1000Mbps. It supports PXE / RPL Boot and Wake On LAN, which can meet the network requirements of industrial control computers.
[0059] In one embodiment, the industrial programmable logic control motherboard includes a first 4P terminal block and a second 4P terminal block; the first 4P terminal block establishes a communication connection with the UART interface on the input / output hub board through a third signal converter, and a serial communication interface is brought out through the first 4P terminal block; the second 4P terminal block establishes a communication connection with the PCIE interface on the input / output hub board through a fourth signal converter, and a control local area network interface is brought out through the second 4P terminal block.
[0060] according to Figure 2 It can be seen that the serial communication interface derived from the first 4P terminal block can be configured as RS232 / RS485 / RS422 to meet the communication requirements between the industrial control computer and the lower-level computer.
[0061] In one embodiment, the industrial programmable logic control motherboard includes a high-definition multimedia interface, a universal serial bus interface, and a hard disk interface; the high-definition multimedia interface, the universal serial bus interface, and the hard disk interface establish communication connections with the input / output hub board, respectively.
[0062] The high-definition multimedia interface is version 1.4a, which connects to the DDI (Data Definition Interface) interface on the input / output hub board. It can achieve a display output resolution of up to 1920*1200, meeting the display requirements of industrial control computers.
[0063] The Universal Serial Bus (USB) interface consists of dual USB 3.2 Gen 2 interfaces, which connect to the USB 3.0 interfaces on the input / output hub board, enabling a maximum transmission rate of 5Gbps to meet the data transmission and peripheral expansion needs of industrial control computers.
[0064] The hard drive interface is a PCIe*2M.2M-Key 2242 hard drive interface, which connects to the PCIe interface on the input / output hub board, enabling the storage expansion needs of industrial control computers to be met even with small-sized hard drive interfaces.
[0065] In one embodiment, the industrial programmable logic controller motherboard includes a real-time clock. The real-time clock establishes a communication connection with an input / output hub board so that the system time of the industrial control computer can be maintained when the power is off. It should be noted that the input / output hub board in this embodiment is equipped with a CR2032 battery for powering the real-time clock.
[0066] This application also provides an industrial control computer, which includes the aforementioned industrial programmable logic control motherboard.
[0067] It is understandable that, since the industrial programmable logic control motherboard mentioned above is used in the industrial control computer, the embodiments of the industrial control computer include all the technical solutions of all embodiments of the industrial programmable logic control motherboard mentioned above, and the technical effects achieved are exactly the same, so they will not be repeated here.
