[0039] Modbus protocol: a commonly used industrial communication protocol used for communication between different devices.

[0040] Mine-Hong System: A variant of the Hongmeng system specifically designed for equipment communication and management in mining environments.

[0041] Device location: refers to an independent identifier established for the device location in IoT applications and device management.

[0042] Device node: represents a redistribution point or communication endpoint, which is used to send, receive or forward information in the network. Its function is to provide a link between user programs and kernel drivers, so that users can interact with hardware devices by reading and writing device nodes. Different device types correspond to different device nodes. The device node status flag describes the status of the device. By creating a device node, you can access and control the device.

[0043] The Kuanghong system is an operating system customized based on OpenHarmony (the open source version of Hongmeng system) for the mining field. At present, most equipment in mines uses protocols for data communication, but the Kuanghong system itself does not directly support the protocol, which makes it difficult for existing equipment to access the Kuanghong system. This means that if you want to connect these devices to the Kuanghong system, you need to develop an additional compatibility mechanism. This incompatibility problem limits the flexibility of mining equipment and increases the cost of replacing new equipment.

[0044] Based on this, the embodiment of the present application provides a networking communication system; exemplary, as Figure 1As shown, the system includes a Modbus master device 100 (i.e., master device) and multiple Modbus slave devices 200 (i.e., slave devices) integrated with the Mine Hong system. Among them, the Modbus master device includes a Modbus service process, multiple NAPI (i.e., Native Application Programming Interface) interfaces and multiple communication interfaces (such as / dev / ttys0 / dev / tty232, etc.). Optionally, the communication interface includes different types of interfaces such as serial ports and Ethernet interfaces. In addition, the slave device includes but is not limited to a programmable logic controller (Programmable Logic Controller, PLC), sensors, actuators, etc.

[0045] It should be noted that this embodiment realizes seamless connection between internal applications or cloud platforms and the Kuanghong system through the NAPI interface in the Modbus master station device; and the Modbus master station device not only solves the compatibility problem by providing a unified NAPI interface, but also greatly simplifies the development process of internal applications.

[0046] It can be understood that this embodiment adds support for the Modbus protocol within the Kuanghong system. By introducing comprehensive support for the Modbus protocol, the cost investment caused by hardware updates can be significantly reduced, while also ensuring seamless communication between new and old devices; and providing a unified NAPI interface, so that the master station device can be suitable for the development of different types of local applications, thereby enabling different types of developers to easily communicate with the master station device.

[0047] Furthermore, if Figure 2 As shown, the Modbus master device builds a communication connection relationship between the internal application and the target slave device through the internal Modbus service process. Among them, the internal application is an application that does not support Modbus service, such as Node.js application.

[0048] It can be understood that this embodiment sets up a special Modbus service process inside the Mine Hong system. This process can use the standard Modbus protocol to communicate with other Modbus devices, and also provides a series of standard interfaces (NAPI) for applications within the Mine Hong system, so that the application can access the Mine Hong system through the NAPI interface.

[0049] When the mining system inside the Modbus master device is started, the Modbus service process will also start and automatically scan the available communication interfaces in the system. The internal application can establish a communication connection with the Modbus slave device by using the Modbus service; wherein, the internal application first provides the corresponding configuration information to the Modbus service process according to the device type of the Modbus slave device to be connected, so that the Modbus service process can create device nodes and point information according to the configuration information, and then actively establish a communication connection with the target slave device according to the point information.

[0050] Based on this, this embodiment implements a Modbus service process in the mining system of the Modbus master device. Externally, it uses the standard Modbus protocol to communicate with other Modbus devices; internally, it provides a variety of NAPI interfaces to transmit the necessary parameter configurations for device communication through the NAPI interface; further, based on the Modbus service process, the communication barriers between the mining system and the Modbus slave device can be broken.

[0051] For reference, Figure 3 As shown, the master station device 100 in the above networking communication system performs the networking communication process which may specifically include the following steps:

[0052] S110, receiving device information of a target slave device to be connected for communication sent by an internal application in a Modbus master device.

[0053] S120, create a device node according to the device information and configure the location information of the device node; establish a communication connection between the internal application and the target slave device according to the location information and the device node information, so that the target slave device can be connected to the Mine Hong system.

[0054] First, when the master station device starts the internal mining system, it automatically starts the internal Modbus service process.

[0055] Furthermore, the application program inside the master station device can realize data interaction with the target slave station device to be connected for communication through the Modbus service process.

[0056] Exemplarily, the internal application sends the device information of the target slave device to be connected for communication to the Modbus service process, wherein the device information corresponds to the device type of the target slave device, that is, the internal application provides corresponding configuration information, such as device type, function code, etc., to the Modbus service process according to the device type of the target slave device, so that the Modbus service process creates device nodes and point information according to the configuration information, and then actively connects to the target slave device.

[0057] It can be understood that the internal application can determine the interface type and supported communication protocol of the Modbus slave device according to the device type of the Modbus slave device; according to the interface type and communication protocol, send the corresponding device information to the Modbus service process. Among them, when the target slave device is a serial port device or an Ethernet device, the corresponding device information is different, and each information item of the specific device information to be transmitted can be set accordingly according to actual needs, and this embodiment does not limit this.

[0058] Among them, if the target slave device is an Ethernet device, such as a Modbus TCP device, the device information includes but is not limited to the IP address, port number, Modbus node number and device type; if the target slave device is a serial port device, such as a ModbusRTU device or a Modbus ASCII device, the device information includes but is not limited to the serial port device number, baud rate and data bits.

[0059] Among them, the Modbus service process can set an event listener or use the framework function to capture events sent by internal applications, especially those involving communication requests or device information; and then parse the device information sent by the application to extract key attribute parameters.

[0060] In one embodiment, before using the Modbus service, the internal application needs to verify its identity through a login interface (such as the / api / login interface), that is, before the internal application sends device information to the Modbus service process to enable the Modbus service process to communicate with the target slave device, the internal application needs to authenticate its identity.

[0061] The internal application sends login information to the Modbus service process, including but not limited to passwords and other information; the Modbus service process receives the login information sent by the internal application and verifies the login information. Furthermore, after the internal application passes the verification, it sends the corresponding device information of the target slave device to the Modbus service process.

[0062] Furthermore, after receiving the device information, the Modbus service process creates a device node and configures the position information of the device node according to the device information. For example, the Modbus service process creates a corresponding device node according to the device information. Then, according to the device type and device information, the position information of the device node is configured, wherein the position information includes each readable and writable device position on the slave device, as well as their address, data type, etc.

[0063] In some examples, the Modbus service process can save the created device nodes and the configured point information to the database or configuration file inside the master station device for subsequent use. In addition, a node management module can also be created to create, manage and update device nodes through the node management module.

[0064] Furthermore, the Modbus service process establishes a communication connection between the internal application and the target slave device based on the point information and device node information, so that the target slave device can be connected to the Mine Hong system.

[0065] For reference, a tag table is created according to the device node information and the point information; if it is determined that the tag table is not empty, a communication connection is established between the internal application and the Modbus slave device according to the device node information in the tag table and the device type of the Modbus slave device.

[0066] That is, after creating the device node, configure the point information of each device node accordingly in order to obtain all address data in the target slave device. In this process, the NAPI interface (such as / api / device / tag / add interface) can be used to send the corresponding device information of the target slave device to the Modbus service process. The Modbus server process uses this configuration information to create a tag table (i.e., tag table).

[0067] Furthermore, when the tag table is not empty, the Modbus service process actively connects to the target slave device through the corresponding communication interface according to the device node information and the device type. For example, if the device type is a TCP device, the TCP method is used to connect according to the port number in the device information, so that the internal application can directly establish communication with the Modbus slave device.

[0068] In one example, after startup, the Modbus service process can automatically search for the hardware information of all communication interfaces inside the master device, and the hardware information of each communication interface is used to indicate the device type of the Modbus slave device to which the corresponding communication interface can be physically connected; then the Modbus service process can select the target communication interface for connecting the target slave device based on the hardware information of each communication interface obtained; wherein the communication interface is a physical port on the master device used for data transmission with other devices, which can be a serial port, Ethernet interface, etc.; for example, a slave device connected to the serial port of the master device is a serial port device, and a slave device connected to the Ethernet interface is an Ethernet device.

[0069] Furthermore, the Modbus service process can read the hardware information of each communication interface inside the master station device according to query commands or APIs, etc. The hardware information includes parameter items such as interface type (serial, Ethernet, etc.), physical address, port number, transmission speed, number of stop bits, baud rate, number of data bits, stop bits, and parity check mode, wherein the hardware information acquisition method and each parameter item of the hardware information to be acquired can be set accordingly according to actual needs, and this embodiment does not limit this.

[0070] Then, according to the value of the corresponding parameter item in the hardware information, it can be determined whether a slave device is currently connected, and according to the type of the communication interface indicated in the hardware information, the device type of the slave device that the communication interface can correspond to. Furthermore, after receiving the device information of the target slave device sent by the internal application and creating the device node and point information, the Modbus service process selects a suitable target communication interface from all the internal communication interfaces to actively establish a communication connection with the target slave device. Among them, the suitable target communication interface is that there is no other slave device currently connected in communication, and the interface type of the target communication interface matches the device type of the target slave device to be connected in communication.

[0071] Furthermore, after establishing a communication connection between the internal application and the target slave device, the internal application can periodically obtain the data of each device point according to the point information of the target slave device through the Modbus service process, and then obtain the status of each device point and change the status of the device point.

[0072] For example, Figure 4 As shown, in the embodiment of the present application, the process of the internal application performing data read and write operations on the target slave device through the Modbus service process may include the following steps:

[0073] S410, the Modbus service process responds to the data collection request sent by the internal application program to encapsulate multiple data read instructions according to the point information, and sends the data read instructions of each device point to the Modbus slave device in sequence through the corresponding communication interface.

[0074] S420, receiving slave station data fed back by each device point in response to a data read instruction, and recording the feedback status of each device point; and determining the working status of each device point according to the feedback status.

[0075] It can be understood that one data read instruction corresponds to one device point, that is, the internal application can send a data read instruction to each device point of the target slave device through the Modbus service process to obtain the data of the device point, and then determine the working status of the device point according to the feedback of the device point; wherein, if the device point does not feedback the slave data according to the data read instruction, it means that the device point is invalid or in an abnormal working state, and if the device point feedbacks the relevant slave data according to the data read instruction, it is determined that the device point is valid and in a normal working state. Among them, the slave data includes the current point value of the device point; the internal application can also modify the point value of the corresponding point of the target slave device accordingly.

[0076] For example, the Modbus service process can set a timer for each device point, and then encapsulate the point information (such as Modbus address, function code, etc.) into a Modbus request packet containing a data read instruction, and send the Modbus request packet to the target slave device through the corresponding communication interface (such as / api / device / tag / status interface), and then receive the feedback information of the target slave device to collect the data or status of the corresponding device point of the target slave device.

[0077] In one example, the internal application can also update the device point information of the target slave device, that is, perform a data write operation. For example, the Modbus service process responds to the point update request sent by the internal application, encapsulates the data write instruction according to the point update request, and sends the data write instruction of the corresponding device point to the Modbus slave device through the corresponding communication interface (such as api / device / tag / set interface), and the data write instruction is used to indicate that the point information of the corresponding device point is updated.

[0078] It can be understood that the internal application sends the point value that needs to be updated for the corresponding device point to the Modbus service process, and the Modbus service process encapsulates the updated point value to obtain a Modbus request packet containing a data write instruction, and then sends the Modbus request packet to the target slave device, so that the target slave device changes the point value of the target device point accordingly.

[0079] The embodiment of the present application uses the NAPI interface and Modbus protocol of the mining system to realize the communication connection between the internal application and the Modbus slave device based on a Modbus service process, which provides feasibility for the Modbus slave device to access the mining system, that is, it can access the internal application or cloud platform through a unified NAPI interface, which simplifies the development difficulty and makes it simple and convenient to implement, thereby saving the cost of equipment replacement and simplifying the development process of internal applications and cloud platforms; it enables slave devices using the Modbus protocol to be more easily connected to the mining system designed specifically for mining scenarios, thereby improving the compatibility and practicality of the system.

[0080] The embodiment of the present application also provides a Modbus master station device integrated with a mining system, and the Modbus master station device integrated with the mining system can be, but is not limited to, an industrial computer, a gateway device, etc. Exemplarily, the Modbus master station device integrated with the mining system includes a processor and a memory, wherein the memory stores a computer program, and the processor includes a Modbus service process, and the processor runs the computer program to enable the Modbus service process to execute the networking communication method of the present application.
