The 5G industrial gateway refers to the key hub connecting industrial devices and the 5G network, and it has the functions of data acquisition, transmission, processing and management. By connecting with various sensors, terminal devices, computers and cloud platforms, the 5G industrial gateway realizes efficient communication and data interaction between industrial devices and between devices and cloud platforms. Traditional industrial gateway devices generally only perform network communication through a single 5G module. Due to the single function, 5G communication anomalies may occur due to single-system anomalies. Summary of the Invention

[0003] Aiming at the above problems, the purpose of the utility model is to provide an industrial gateway device with dual-module and dual-master timing and positioning, which avoids 5G communication anomalies caused by single-module or single-system anomalies and ensures the stability of dual-link communication. At the same time, an FPGA hardware module and a GPS module are integrated on the gateway, which can transmit GPS / 5G time data and positioning data to the acquisition subsystem in real time. The timing and positioning requirements of the industrial field are met.

[0004] To achieve the above purpose, the solution of the utility model is: an industrial gateway device with dual-module and dual-master timing and positioning, including two 5G communication modules, namely the first 5G communication module and the second 5G communication module, wherein: the two 5G communication modules are respectively connected and controlled by two main control CPUs, that is, the first main control CPU is connected to control the first 5G communication module, the second main control CPU is connected to control the second 5G communication module, and the first main control CPU and the second main control CPU are connected together through the PHY-to-PHY MDI method to form two 5G network channels. One of the 5G network channels has timing data output. The main control CPU and the 5G communication module of the 5G network channel with timing data output are respectively connected to a data input end of an FPGA data transmission module through an asynchronous transceiver. The connection end of the 5G communication module to the FPGA data transmission module is set as a timing data output end for outputting timing data to the FPGA data transmission module. The data input end of the FPGA data transmission module is also connected to a GPS positioning chip.

[0005] Further, the main control CPU uses a main control chip with the model number MT7621; the GPS positioning chip uses a chip with the model number GNSS-T030RSA2; the FPGA data transmission module is a Cyclone series FPGA data transmission module.

[0006] Further, the two 5G network channels are arranged as the main control system on a PCB circuit board, and the FPGA data transmission module together with the GPS positioning chip and the clock chip are arranged as the FPGA daughter board on another PCB circuit board. The FPGA daughter board is connected to a 5G network channel of the main control system through an interface socket.

Among them: the FPGA data transmission module connected to a 5G network channel is externally provided with a time synchronization and positioning data serial port output channel.

[0008] The beneficial effects of the present utility model are as follows:

[0012] Figure 1 It is a schematic block diagram structure of the present utility model. Detailed Embodiments

[0013] An industrial gateway device with dual modules and dual main control for time synchronization and positioning, as Figure 1 shown, the industrial gateway device includes two 5G communication modules, namely the first 5G communication module 1 and the second 5G communication module 2. Among them: the two 5G communication modules are respectively connected and controlled by two main control CPUs, and the two main control CPUs are respectively the first main control CPU 3 and the second main control CPU 4, that is, as Figure 1As shown, the first master CPU 3 is connected to control the first 5G communication module 1, and the second master CPU 4 is connected to control the second 5G communication module 2. The first master CPU 3 and the second master CPU 4 are connected together through the PHY-to-PHY MDI (Medium Dependent Interface) to form two 5G network channels. One of the 5G network channels has timing data output, such as Figure 1 As shown, the first master CPU 3 and the first 5G communication module 1 of the 5G network channel with timing data output are respectively connected to a data input end of an FPGA data transmission module 6 through an asynchronous transceiver (UART interface) 5. The connection end of the first 5G communication module to the FPGA data transmission module 6 is set as a timing data output end for outputting timing data to the FPGA data transmission module 6. The data input end of the FPGA data transmission module 6 is also connected to a GPS positioning chip 7. The FPGA data transmission module is connected to a clock chip 8 required by itself. The master CPU connected to the FPGA data transmission module is used to output a pulse signal to the FPGA data transmission module 6 through an asynchronous transceiver (UART interface). Of course, the second master CPU 4 and the second 5G communication module 2 can also be connected to the FPGA data transmission module 6.

[0014] In the embodiment: the master CPU uses a master chip with the model MT7621, and the GPS positioning chip uses a chip with the model GNSS-T030RSA2; the FPGA data transmission module 6 is a Cyclone series FPGA data transmission module; since each of the two 5G network channels is controlled and operated by the master CPU. Therefore, the two 5G network channels operate independently and do not affect each other. The two master CPU chips are connected together through the hardware link PHY-to-PHY MDI, and the dual master CPUs can work simultaneously at the hardware level, so that the industrial gateway achieves the effect of dual master and dual systems. And because the two master CPU chips and systems work independently, each master CPU has independent supporting hardware. Therefore, during the use of the industrial gateway, whether there is an abnormality in the system or the supporting hardware where either master CPU is located will not affect the normal operation of the other system and hardware. The two 5G modules provide two 5G network communication channels at the same time, so that the industrial gateway has the ability to have two 5G links working simultaneously and not affecting each other, which ensures the reliability of the industrial gateway.

[0015] In this embodiment, the first master CPU enables the first 5G communication module through a pulse signal to transmit the 5G network timing data inside the module to the FPGA data module through the hardware UART channel. At the same time, the FPGA module can also receive the GPS positioning data generated in the GPS chip and control the receiving and sending frequencies of the FPGA serial port under the action of the clock, so that the external customer system can obtain the 5G / GPS timing data and positioning data simultaneously through the external serial port of the FPGA data module.

[0016] Among them: the two 5G network channels are arranged as the main control system on a PCB circuit board, and the FPGA data transmission module 6 together with the GPS positioning chip 7 and the clock chip 8 are arranged as the FPGA daughter board 9 on another PCB circuit board. The FPGA daughter board 9 is connected to one of the 5G network channels of the main control system through an interface socket. This structure makes the application of the gateway more flexible, and the FPGA daughter board 9 can be connected to any one of the two 5G network channels according to needs.

[0017] In the embodiment: each of the two 5G network channels is externally provided with a network interface, a SIM card holder and a USB interface. Among them: the FPGA data transmission module connected to one of the 5G network channels is externally provided with a timing and positioning data serial port output channel 10.

[0018] In the above industrial gateway embodiment, due to the hardware design method of dual-module and dual-master CPU control, two non-interfering 5G links can be established to ensure the stability of 5G communication. At the same time, due to the particularity of the dual-master, any abnormality in the hardware, system or software of any part will not affect the normal operation of the other master. In the industrial application environment, the applicability and stability of the device are improved.
