The upper and lower layers are arranged through the connection plate 1 3 and the connection plate 2 14, which is convenient for optimizing the utilization of the internal space structure and facilitating the installation, expansion and addition of the later interface. The power module 25 installed inside the gateway shell 1 is charged during the power-on period and provides stable power support for the hardware in the gateway during the power-off period;

[0050] A SIM card slot 15 is installed on one side of the upper surface of the second connection board 14, and an expansion input port 16 and an expansion output port 17 are installed on the other side of the upper surface of the second connection board 14. An expansion module 22, a storage module 23, and a multi-protocol communication module 24 are installed on the upper surface of the second connection board 14 in sequence. The multi-protocol communication module 24 receives the signal processed by the main control module 21, and the signal output by the multi-protocol communication module 24 is output to the outside through the 12V output port 13 and the expansion output port 17. A high-performance processor unit, a cache unit, a memory controller module, and a terminal controller unit are arranged in the main control module 21, and the main control module 21 interacts with the storage module 23;

[0051] The data processing module 20 is provided with a data acquisition submodule, a data preprocessing submodule, a data forwarding submodule and an edge intelligent analysis submodule, and the data processing module 20 receives and sends the signal input by the extension module 22, and the data processing module 20 transmits it to the main control module 21;

[0052] The power module 25 supplies power to the data processing module 20, the main control module 21, the expansion module 22, the storage module 23 and the multi-protocol communication module 24. The multi-protocol communication module 24 is provided with a communication interface chip unit, a protocol processing unit, an antenna unit and a signal conditioning unit, and the multi-protocol communication module 24 receives signals from the main control module 21.

[0053] In conjunction with the accompanying drawings Figure 1-Figure 7As shown, when in use, the data processing module 20, the main control module 21, the expansion module 22, the storage module 23 and the multi-protocol communication module 24 cooperate with each other, wherein the data processing module 20 receives the port data information installed on the connection board 3, and the expansion module 22 receives the port data added from the expansion input port 16. At the same time, the expansion module 22 is connected to the supporting expansion hardware, such as an additional storage device, a dedicated encryption chip or a special industrial communication adapter module, so as to facilitate the communication use of the expansion device. The processed data information is transmitted to the inside of the data processing module 20 in the same direction, and the data is filtered, verified and normalized by the cooperation of the data acquisition submodule and the data preprocessing submodule. The data forwarding submodule provides technical support for data transmission and forwards the data to the cloud or the main body server. At the same time, the edge intelligent analysis submodule uses the built-in AI algorithm to analyze the data in real time, and provides early warning, diagnosis and other functions, so as to realize the processing and reply of simple data and reduce the total amount of data forwarded by the data forwarding submodule.

[0054] An ARM Cortex-A series processor is set in the high-performance processing unit set in the main control module 21, and an Intel Atom processor is added for high-performance data processing. During the processor processing, the storage module 23 cooperates with the cache unit to provide temporary storage for a large amount of data to reduce the access pressure of the memory. The memory controller unit must be able to efficiently process a large number of data read and write requests. When multiple devices transmit data at the same time and need to store data in the memory or read data from the memory for processing, the memory controller coordinates the CPU's read and write operations on the memory to ensure accurate data transmission;

[0055] The interrupt controller unit is used to process interrupt requests from various external devices. When a device has an emergency event that needs to notify the processor, such as device access, data transmission error, etc., an interrupt signal will be sent to the interrupt controller. The interrupt controller sorts these requests according to the interrupt priority, and then passes the interrupt request to the CPU to ensure that important device events can be responded to by the CPU in a timely manner, improve the real-time performance and reliability of the system, and the processed data is sent to the multi-protocol communication module 24;

[0056] The industrial communication protocols of the multi-protocol communication module 24 include but are not limited to mainstream industrial communication protocols such as Modbus-RTU, Modbus-TCP, DL645 and IEC104, among which the communication interface chip unit is responsible for the communication functions of the physical layer and the data link layer, converts electrical signals or optical signals into digital signals, and encapsulates and decapsulates data frames in accordance with the format specified by the corresponding protocol. The protocol processing unit runs on the communication interface chip or exists as an independent chip, and is mainly responsible for parsing and processing different communication protocols, for understanding the rules and semantics of the protocol, and can identify the control information and data information in the protocol, so as to correctly route the received data to the corresponding application or assemble the sent data according to the protocol requirements;

[0057] The antenna unit is used for transmitting and receiving wireless signals in wireless communication protocols. Its performance directly affects the distance, quality and stability of communication. The model conditioning unit is used for amplifying, filtering, matching and other processing of communication signals in some communication protocols to ensure the integrity and accuracy of the signal during transmission. It can remove noise from the signal, adjust the amplitude and phase of the signal, etc., so that the signal can meet the reception requirements of the communication interface chip;

[0058] As the device accesses and interacts with the gateway, the device sends data to the gateway according to its own communication protocol. The gateway's multi-protocol communication module 24 receives the data and passes it to the protocol conversion layer for protocol conversion and preprocessing. The processed data enters the application service layer, where caching, edge computing and other operations are performed according to the type and requirements of the data. The data is then transmitted to the target device or cloud server, thereby enabling the data to quickly select the corresponding protocol between different protocols for data transmission.

[0059] Working principle: When using the highly scalable smart gateway, first turn on the power supply and start the gateway device, so that the main control module 21 performs initialization detection on each hardware and module, including checking whether the memory and flash memory are working properly, whether the multi-protocol communication module 24 can start normally and search for signals, etc. During this period, the power module 25 performs storage charging to provide temporary power supply assistance for sudden power outages in the industrial plant. As the cable is inserted into the corresponding USB interface 4, network port connection terminal 7, 220V input port 8 or double-row 485 port 12 for connection, the prepared SIM card is inserted into the SIM card socket 15 for installation, and the electrical signal input through the data processing module 20 receiving port is processed and integrated At the same time, the extension module 22 receives the data transmission from the extension input port 16, and the edge intelligent analysis submodule set in the data processing module 20 quickly processes some simple data to reduce the total amount of data. After the storage module 23 cooperates to cache the data information, the main control module 21 processes the information in turn and transmits it to the multi-protocol communication module 24. Through the initial configuration, the working mode and parameters are flexibly switched to adapt to the communication requirements of different devices. The multi-protocol communication module 24 receives the data and passes it to the protocol conversion layer for protocol conversion and preprocessing. The processed data enters the application service layer, and caches, edge computing and other operations are performed according to the type and requirements of the data, and then the data is transmitted to the target device or cloud server.
