[0056] 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.

[0057] In one embodiment, an edge computing gateway is provided, the edge computing gateway comprising an edge gateway module and a routing module. The edge gateway module comprises a first data interface, the routing module comprises a second data interface, and the first data interface is connected to the second data interface.

[0058] The edge gateway module includes an edge computing algorithm processor. The edge gateway module obtains edge device data and / or sensor data through the routing module, then transmits the edge device data and / or sensor data to the edge computing algorithm processor, pre-processes it based on a preset edge computing algorithm or data processing model to obtain processed edge device data and / or processed sensor data, and then transmits the processed edge device data and / or processed sensor data to the cloud platform through the routing module.

[0059] The routing module includes a routing processor. When the cloud platform transmits control instructions and / or data to the edge device, the routing module transmits the control instructions and / or data to the edge gateway module, and processes the received control instructions and / or data through the edge computing algorithm processor to obtain the control instructions and / or data of different edge devices. The routing module uses the routing processor to select a suitable transmission path based on the control instructions and / or data of different edge devices to transmit the control instructions and / or data of different edge devices to the corresponding edge devices.

[0060] In this embodiment, the internally arranged edge gateway module is directly connected to the routing module, and the edge computing algorithm processor is connected to the routing processor through the first data interface and the second data interface. The edge computing gateway obtains edge device data from the edge device and preprocesses the edge device data to obtain processed edge device data. The routing module receives the processed edge device data transmitted by the edge computing gateway and can transmit it to the cloud platform, or the routing module transmits the instructions or data issued by the cloud platform to the edge computing gateway. After being processed by the edge computing gateway, the routing module selects a suitable transmission path to transmit different data or instructions to the corresponding edge device. The edge computing algorithm processor and the routing processor are directly connected based on the data interface, and the communication between the processors is realized by using the pre-set underlying driver simulation. There is no need for middleware devices to realize the communication connection between the processors, thereby reducing hardware costs, avoiding the processing of communication by middleware devices, and improving communication efficiency.

[0061] In an exemplary embodiment, the first data interface and the second data interface both use a Gigabit Media Independent Interface, that is, the first data interface is a first Gigabit Media Independent Interface and the second data interface is a second Gigabit Media Independent Interface. The Gigabit Media Independent Interface is a Reduced Gigabit Media Independent Interface (RGMII) interface.

[0062] like Figure 1 As shown, the pins of the Gigabit Media Independent Interface include a clock signal pin, a control signal pin and a data transmission pin, and the clock signal pin, the control signal pin and the data transmission pin are divided into output pins and input pins. The transmitting pin of the first Gigabit Media Independent Interface is connected to the receiving pin of the second Gigabit Media Independent Interface, and the receiving pin of the first Gigabit Media Independent Interface is connected to the transmitting pin of the second Gigabit Media Independent Interface.

[0063] In an exemplary embodiment, Figure 2 As shown, the edge gateway module also includes a first storage module and a first interface module, and the first storage module and the first module are both connected to the edge computing algorithm processor of the edge gateway module. And the first storage module includes a first DRAM (Dynamic Random Access Memory) module and an eMMC storage module. The first DRAM storage module can be but is not limited to DDR4

[0064] The eMMC storage module uses an SD (Secure Digital, independent storage medium) card channel and is connected to the edge computing algorithm processor based on 8 data lines.

[0065] In an exemplary embodiment, see Figure 2The first interface module includes a device expansion module and a serial communication module, and both the device expansion module and the serial communication module are connected to the edge computing algorithm processor of the edge gateway module. The device expansion module includes a USB (Universal Serial Bus) expansion interface module, specifically a USB Hub module. The serial communication module includes an RS232 serial port module and an RS485 serial port module, and both the RS232 serial port module and the RS485 serial port module use a UART (Universal Asynchronous Receiver / Transmitter) serial communication protocol to communicate with the edge computing algorithm processor.

[0066] In an exemplary embodiment, see Figure 2 The routing module also includes a second storage module, which includes a second DRAM storage module and a flash memory storage module. The second DRAM storage module uses DDR3

[0067] The memory module is a Double-Data-Rate Third Generation Synchronous Dynamic Random Access Memory (DDRMM), and the flash memory storage module uses a NOR-Flash flash memory module, which is read and written through a SPI (Serial Peripheral interface) channel.

[0068] In an exemplary embodiment, see Figure 2 The routing module also includes a wireless communication module, and the wireless communication module adopts a 4G module or a 5G module.

[0069] In an exemplary embodiment, Figure 3 As shown, a method for configuring inter-processor communication is provided, and the method includes the following steps 302 to 306. Among them:

[0070] Step 302, when compiling the operating system, modify the configuration of the device tree file according to the preset configuration parameter data to obtain a modified device tree file and a modified operating system.

[0071] Exemplarily, when compiling the operating system of the edge computing algorithm processor or the routing processor, search for nodes related to the Ethernet node in the device tree file, and search or add the phy-mode (Physica-mode, physical layer mode) attribute under the node, and set it to the rgmii-rxid (Reduced Gigabit Media Independent Interface, reduced gigabit media independent interface) attribute. rgmii-rxid means delay processing of received data in the virtual phy, and configuration settings are performed to obtain the modified device tree file and the modified operating system.

[0072] Step 304: Transmit the modified device tree file and the modified operating system to the target processor.

[0073] Among them, the target processor includes an edge computing algorithm processor and a routing processor.

[0074] Exemplarily, an operating system suitable for a corresponding edge computing algorithm processor or a routing processor is transmitted to a corresponding processor, ie, a target processor.

[0075] Step 306: Run the modified operating system in the target processor, perform virtual creation according to the preset configuration function and the modified device tree file, and obtain a virtual physical layer device.

[0076] Among them, the preset configuration function is the phy_connect_fixed (Physica_connect_fixed, physical layer fixed connection) function.

[0077] Exemplarily, when the edge computing algorithm processor or the routing processor is running, the modified operating system is started, and a virtual PHY device is created based on the configuration information in the modified device tree file using a preset configuration function. The specific process is: the modified device tree file is loaded into the memory, and then the memory is passed to the kernel of the target processor, the kernel parses the modified device tree file and initializes and configures the modified operating system, creates a virtual PHY device, and assigns it a virtual ID.

[0078] In the above-mentioned inter-processor communication configuration method, the communication between processors is realized by pre-setting the underlying driver simulation, and no middleware device is required to realize the communication connection between processors, thereby reducing hardware costs, avoiding the processing of communication by middleware devices, and improving communication efficiency.

[0079] In an exemplary embodiment, modifying the configuration of a device tree file according to preset configuration parameter data to obtain a modified device tree file and a modified operating system includes:

[0080] Acquire the attribute data to be modified from the device tree file; modify the attribute data to be modified according to the preset configuration parameter data to obtain the modified attribute parameter data.

[0081] For example, find the node related to Ethernet in the device tree file, find or add the phy-mode attribute under the node, and set it to the rgmii-rxid attribute, where rgmii-rxid indicates delay processing of received data in the virtual phy. Then add attributes to the node to specify the communication mode and rate, such as setting the full-duplex mode and the communication rate to 1000bps.

[0082] In this embodiment, the device tree file is modified at the compile time of the operating system to use Fixed PHY to drive the RGMII interface, simulate the function of PHY, and realize direct communication between the edge computing algorithm processor and the routing processor, thereby improving the data transmission speed and saving hardware costs.

[0083] In an exemplary embodiment, a method for configuring inter-processor communication is provided, the method comprising the following steps:

[0084] When compiling the operating system, the attribute data to be modified is obtained from the device tree file.

[0085] The attribute data to be modified is modified according to the preset configuration parameter data to obtain the modified attribute parameter data.

[0086] Transfer the modified device tree file and the modified operating system to the target processor.

[0087] The modified operating system is run in the target processor, and virtual creation is performed according to the preset configuration function and the modified device tree file to obtain a virtual physical layer device.
