[0032] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0033] It is to be understood that the terminology "first" and "second", and the like, used herein is merely intended to differentiate one entity or operation from another, without necessarily requiring or implying any actual relationship or order between such entities or operations. Also, the use of terminology "comprises", "comprising", or any other forms of the expression "comprises" used herein is not intended to refer to a closed or exhaustive list, but to allow for the inclusion of additional elements, not expressly listed or inherent to such process, method, article, or apparatus. Without further limitations, the elements defined by the statement "comprises" do not exclude the presence of additional identical elements in the process, method, article, or apparatus including the elements defined by the statement "comprises".

[0034] The existing industrial network solution is a five-layer architecture, including two layers of enterprise-level platform and workshop-level platform, three layers of field network, including production line control network, device control network and physical device network. The three layers of field network have strict requirements on network performance, and custom industrial Ethernet / fieldbus protocol is used, so how to reasonably allocate resources and schedule communication requests of different protocols is a key problem. In the prior art, when transmitting data, the data is transmitted according to the receiving time, and the protocol data is transmitted and processed according to the order of arrival, and the transmission data arriving earliest will be processed first. However, an industrial network usually contains a large number of devices, sensors and control systems, and due to the existence of devices of different protocols and levels, different transmission data generated have different priorities and the transmission bandwidth is limited. If the data arriving earliest is low-priority data, these data will be transmitted first. The high-priority data arriving later needs to wait until the transmission of the low-priority data arriving earliest is completed before being transmitted, and the high-priority data is delayed in transmission and processing, resulting in low efficiency of data processing.

[0035] To solve the prior art, the embodiment of the application provides a data transmission method, device and equipment, computer storage medium and program product. The method first acquires transmission data in an industrial Ethernet protocol format, so that multiple protocol data from different industrial devices can be received and converted into an industrial bus protocol that can adapt to the requirements of different execution devices, ensuring that the data can be correctly and accurately transmitted to the target execution device. The transmission data set is determined according to the size of the transmission data, the preset execution priority and the transmission bandwidth size; by comprehensively considering the data size, priority and bandwidth, the order and mode of data transmission can be optimized, and the key data can be transmitted in priority. Finally, the transmission data in the transmission data set is sent to the execution device. By comprehensively considering the data size, execution priority and bandwidth factors, the order of data transmission is optimized, ensuring that the data can be transmitted to the execution device in time according to the priority for processing, reducing the delay of key operations and improving the efficiency of system data processing.

[0036] Firstly, the data transmission system provided by the embodiment of the application is introduced.

[0037] Figure 1 The structure schematic diagram of the data transmission system 100 provided by an embodiment of the application is shown. As shown in the figure, Figure 1 The system can include a protocol conversion device 110, a scheduling device 120 and an execution device 130.

[0038] The protocol conversion device 110 is used to acquire transmission data in an industrial Ethernet protocol format, and convert the transmission data into an Ethernet protocol format and then transmit it to the scheduling device; the scheduling device 120 includes a protocol identification module 121, a protocol conversion module 122 and a protocol scheduling module 123, the protocol identification module 121 is used to identify the protocol type of the received transmission data, the protocol conversion module 122 is used to convert the received transmission data into an industrial bus protocol format, and the protocol scheduling module 123 is used to determine the data transmission set according to the data size, the preset execution priority and the transmission bandwidth size of the transmission data, and send the transmission data in the data transmission set to the corresponding execution device; the execution device 130 is used to receive and process the transmission data sent by the scheduling device.

[0039] The data transmission method provided by the embodiment of the application is introduced.

[0040] Figure 2 The flowchart of the data transmission method provided by an embodiment of the application is shown. As shown in the figure, Figure 2 The method can include the following steps: S201 to S203.

[0041] S201, acquiring transmission data, the transmission data being in an industrial Ethernet protocol format.

[0042] The acquired transmission data is collected from different industrial control devices and needs to be transmitted, usually in the form of an industrial Ethernet protocol, for connecting industrial devices and systems.

[0043] The industrial Ethernet protocol is an industrial communication protocol based on Ethernet technology, used for connecting industrial devices and systems. Industrial Ethernet connects multiple devices through switches and other devices to realize communication and data exchange between devices.

[0044] In some embodiments, the transmission data is acquired through a device connection interface, such as a serial port, an Ethernet interface, or a sensor, etc.

[0045] The transmission data can also be acquired through wireless communication technology, such as Bluetooth, ZigBee protocol, or Long Range Wide Area Network (LoRaWAN).

[0046] In some embodiments, the industrial Ethernet protocol can include EtherNet / Industrial Protocol, Modbus Transmission Control Protocol (Modbus TCP), and PROFINET.

[0047] S202, convert the transmission data into an industrial bus protocol format.

[0048] In some embodiments, the data in the industrial Ethernet protocol format can be converted into data in the industrial bus protocol format using a protocol converter or preset rules.

[0049] The industrial bus protocol is a serial communication protocol used to connect and control devices in an industrial automation environment. The industrial bus uses a bus structure to connect multiple devices through a bus to realize communication and data exchange between devices.

[0050] In some embodiments, the industrial bus protocol can include Modbus Real-Time Under serial communication (Modbus RTU), PROcess FIeldBUS (PROFIBUS), and Controller Area Network (CAN).

[0051] The protocol data of different industrial devices can be converted into the industrial bus protocol, which can adapt to the needs of different execution devices, can uniformly process data from different sources, and does not need to configure a receiving and processing system for each protocol, thereby simplifying the complexity of the system and improving the flexibility and scalability of the system.

[0052] Since the industrial Ethernet protocol is used to connect industrial devices and systems, different industrial devices may support different industrial Ethernet protocols, and therefore it is necessary to convert the industrial Ethernet protocol format into the industrial bus protocol so that data can be transmitted in different industrial devices and systems.

[0053] S203, determining a data transmission set according to the data size of the transmission data, the preset execution priority and the transmission bandwidth size.

[0054] In some embodiments, the preset execution priority can be preset in the transmission data, and obtained through the data content of the transmission data.

[0055] In the industrial control network, different devices have different data transmission needs, and the transmission bandwidth of the network is limited. According to the size of the data, the preset execution priority and the available transmission bandwidth, it is determined which data should be transmitted first, which optimizes the use of network resources and ensures that critical task data can be transmitted in time.

[0056] S204, sending the transmission data in the data transmission set to the corresponding execution device.

[0057] The data in the data transmission set that has been determined is sent to the corresponding execution device, so that the corresponding execution device performs the corresponding operation.

[0058] It is ensured that data with higher priority can be transmitted and processed first, thereby improving the efficiency of data processing.

[0059] The transmission data is obtained, and the transmission data is in the industrial Ethernet protocol format; so that multiple protocol data from different industrial devices can be received and converted into the industrial bus protocol, which can adapt to the needs of different execution devices and ensure that data can be correctly and accurately transmitted to the target execution device. The transmission data set is determined according to the size of the transmission data, the preset execution priority and the transmission bandwidth size; by comprehensively considering the data size, priority and bandwidth, the order and mode of data transmission can be optimized, and it is ensured that critical data is transmitted first. Finally, the transmission data in the transmission data set is sent to the execution device according to the transmission data set. By comprehensively considering the data size, execution priority and bandwidth factors, the order of data transmission is optimized, it is ensured that data can be transmitted to the execution device in time according to the priority, the delay of critical operation is reduced, and the efficiency of system data processing is improved.

[0060] In some embodiments, asFigure 3 As shown, determining the data transmission set according to the data size of the transmission data, the preset execution priority and the transmission bandwidth size can include S301 and S302.

[0061] S301, in the case where the preset execution priorities of the transmission data are different, sorting the transmission data according to the preset execution priorities;

[0062] S302, selecting the transmission data in the sorted order to join the preset set in sequence to obtain the data transmission set, and the total data size of the transmission data in the data transmission aggregation does not exceed the transmission bandwidth size.

[0063] By sorting the transmission data according to the preset execution priority and selecting the transmission data to join the preset set in sequence according to the transmission bandwidth size limit, it can be ensured that the high-priority data is transmitted in priority under the premise that the total data size of the transmission data does not exceed the transmission bandwidth size, and the order of data transmission is optimized, thereby improving the response speed of the system to critical data.

[0064] In some embodiments, as shown, Figure 4 determining the data transmission set according to the data size of the transmission data, the preset execution priority and the transmission bandwidth size can include S401 to S403.

[0065] S401, in the case where the preset execution priorities of the transmission data are the same, determining the total data size of the transmission data according to the data size of the transmission data;

[0066] S402, establishing a target optimization model with the maximum total data size as the objective function;

[0067] S403, solving the target optimization model with the transmission bandwidth size as the constraint condition to obtain the data transmission set.

[0068] By establishing an optimization model with the maximum total data size as the objective and solving the model with the transmission bandwidth size as the constraint condition, it can be ensured that as much data as possible is transmitted under the premise of meeting the bandwidth constraint, which helps to improve the efficiency of data transmission; and with the transmission bandwidth size as the constraint condition, the data transmission set can be dynamically adjusted to adapt to changing network conditions and optimize data transmission according to real-time bandwidth availability.

[0069] The data transmission set determination method of the preset execution priority different transmission data and the preset execution priority same transmission data can be used in combination. For example, when the preset execution priority different transmission data and the preset execution priority same transmission data exist simultaneously, first, the preset execution priority is sorted, and the preset set is sequentially added according to the priority order; when the transmission data corresponding to a preset execution priority of a certain level cannot be simultaneously added to the preset set, a target optimization function is established and solved, and part of the transmission data corresponding to the preset execution priority of the certain level is selected to be added to the preset set, to obtain the data transmission set.

[0070] In some embodiments, the formula of the data transmission set can be expressed as:

[0071]

[0072] wherein n is the number of transmission data, p i is the preset execution priority of the i th transmission data, w i is the data packet size of the i th transmission data, x i is whether the i th transmission data is selected, and takes the value of 0 or 1, 0 representing that the transmission data is not selected, and 1 representing that the transmission data is selected.

[0073] The formula of the constraint condition can be expressed as:

[0074]

[0075] wherein c is the transmission bandwidth size.

[0076] In some embodiments, the target optimization model is solved with the transmission bandwidth size as the constraint condition, and the branch and bound method, the Lagrange multiplier method, the dynamic programming method, etc. can be used to solve the target optimization model.

[0077] In some embodiments, the target optimization model is solved with the transmission bandwidth size as the constraint condition, to obtain the data transmission set, which can include:

[0078] Selecting any transmission data to create two branch nodes, wherein the two branch nodes are the selected transmission data and the unselected transmission data, respectively;

[0079] Repeating the establishment of the branch nodes of the remaining transmission data under the branch nodes, and removing the branch when the total data size of the transmission data in the branch exceeds the transmission bandwidth size;

[0080] Selecting the transmission data with the largest total data size in the branch to be added to the preset set, to obtain the data transmission set.

[0081] By creating branch nodes for each transmission data, all possible data transmission combinations are simulated, while removing the branch when the total size of transmission data in the branch exceeds the transmission bandwidth, avoiding evaluating all data combinations, which can effectively reduce the waste of computing resources; Finally, the transmission data with the largest total data size in the branch is selected to join the preset set, ensuring that as much data as possible is transmitted under the bandwidth limit.

[0082] In one example, when there are three transmission data with the same preset execution priority, first select any transmission data as the first target data, and establish a branch node that selects the first target data and does not select the second target data; select any data from the remaining two transmission data as the second target data, and establish four branch nodes that select the second target data and do not select the second target data under the branch node that selects the first target data and does not select the second target data; determine whether the total data size of the selected transmission data in each branch exceeds the transmission bandwidth size, and delete the branch if it exceeds the transmission bandwidth size; select the remaining transmission data as the third target data, and establish branch nodes that select the third target data and do not select the third target data under the remaining branch nodes; determine whether the total data size of the selected transmission data in each branch exceeds the transmission bandwidth size, and delete the branch if it exceeds the transmission bandwidth size; finally, select all transmission data selected by the branch with the largest total data size of transmission data to join the preset set as the data transmission set.

[0083] In some embodiments, after repeatedly establishing branch nodes for the remaining transmission data under the branch node and removing the branch when the total data size of the transmission data in the branch exceeds the transmission bandwidth size, the method can further include:

[0084] Selecting all transmission data selected by the branch with a difference between the total data size and the transmission bandwidth size less than a set threshold to join the preset set as the data transmission set.

[0085] When creating branch nodes, only branches with a difference between the total data size and the transmission bandwidth size less than a set threshold are selected, and when the size of the transmission bandwidth used meets the set threshold, the data transmission set is generated, reducing the traversal of all transmission data and improving transmission efficiency.

[0086] In some embodiments, converting the transmission data into an industrial bus protocol format can include:

[0087] Converting the transmission data in the industrial Ethernet protocol format into an Ethernet protocol format;

[0088] Converting the transmission data in the Ethernet protocol format into an industrial bus protocol format.

[0089] By converting data from the industrial Ethernet protocol format to a common Ethernet protocol format, compatibility with a wider range of network devices can be achieved, enabling data transmission between different devices; converting data to a specific industrial bus protocol format facilitates tighter integration and communication with industrial equipment and systems.

[0090] In some embodiments, such as Figure 5 As shown, converting transmission data in the industrial Ethernet protocol format to the Ethernet protocol format can include S501 and S502.

[0091] S501 parses the transmitted data according to the Industrial Ethernet protocol to obtain the structure and corresponding fields of the transmitted data;

[0092] S502 maps the structure and fields of the transmitted data to the structure and fields of the Ethernet protocol format according to the Ethernet protocol format and adds the Ethernet protocol header to obtain the transmitted data in the Ethernet protocol format.

[0093] By parsing transmitted data according to the Industrial Ethernet protocol, the structure and fields of the data can be accurately identified, which helps to ensure the integrity and accuracy of the data during the conversion process; mapping the structure and fields of Industrial Ethernet protocol format data to Ethernet protocol format ensures the consistency and compatibility of data between Industrial Ethernet protocol and Ethernet protocol.

[0094] During the parsing process according to the Industrial Ethernet protocol, a predefined protocol feature library is used for matching. By comparing data features with known protocol features, the data can be classified and its corresponding Industrial Ethernet protocol can be determined.

[0095] In some embodiments, data is transmitted in the form of data packets, such as... Figure 6 As shown, the packet format can include a header and a data portion. The header consists of a fixed portion and a variable portion. The fixed portion includes the version, header length, differentiated services, total length, identifier, flags, fragment offset, time to live, protocol, header checksum, source address, and destination address. The variable portion includes optional fields of variable length and padding data.

[0096] Wherein, the version indicates the version of the data packet format, used to indicate the protocol version used by the data packet; the header length indicates the total length of the header, including the fixed part and the variable part; the differentiated service is used to provide the differentiation of the quality of service (QoS), allowing the network to provide different levels of service according to the field of the data packet; the total length indicates the length of the entire data packet, including the header and the data part; the identification is a unique identifier, used to identify each piece of data sent; the flag is used to control and identify the specific functions of the data packet, such as whether to allow segmentation, etc.; the fragment offset is used to indicate the position of the current fragment in the original data when the data packet is transmitted by fragmentation; the time to live indicates the maximum number of routers that the data packet can pass through in the network. Every time a router is passed, the value is reduced by 1, and when it is 0, the data packet is discarded; the protocol indicates the type of upper layer protocol carried by the data packet; the header checksum is used to check the header, to detect whether an error occurs in the header during transmission; the source address indicates the network address of the device sending the data packet, and the destination address indicates the network address of the device receiving the data packet.

[0097] The optional field contains some additional, optionally required header fields, used to support specific network functions, such as security parameters, routing options, etc.; some padding bytes are added at the end of the header to ensure that the length of the header is a multiple of 32 bits.

[0098] In some embodiments, before obtaining the transmission data in the Ethernet protocol format, the method further comprises:

[0099] Adding a transmission control information field in the transmission data.

[0100] The transmission control information can include data priority, flow control information, security control information, transmission timestamp, and data packet sequence number, etc., and the security control information can include an encryption key or an authentication mark.

[0101] The transmission control information field contains important control information, and by adding the transmission control information field, the data transmission process can be more accurately controlled, which helps to ensure the reliability of the data during transmission.

[0102] In some embodiments, before obtaining the transmission data in the Ethernet protocol format, the method further comprises:

[0103] Adding a check field in the transmission data.

[0104] By adding a check field in the transmission data, it can be verified whether the received data is consistent with the data from the sending end, so as to check whether an error occurs in the data transmission process, which can significantly reduce the error rate in data transmission and improve the accuracy of data transmission.

[0105] In some embodiments, the transmission data in the Ethernet protocol format is converted into the industrial bus protocol format, including:

[0106] The transmission data is parsed according to the Ethernet protocol format to obtain the structure and corresponding fields of the transmission data;

[0107] According to the industrial bus protocol format, the structure and fields of the transmission data are mapped to the structure and fields of the industrial bus protocol format and an industrial bus protocol header is added to obtain the transmission data in the industrial bus protocol format.

[0108] By parsing the transmission data according to the Ethernet protocol, the structure and fields of the data in the Ethernet protocol format can be accurately identified, which helps to ensure the integrity and accuracy of the data in the conversion process; mapping the structure and fields of the data in the Ethernet protocol format to the industrial bus protocol format ensures the consistency and compatibility of the data between the Ethernet protocol and the industrial bus protocol.
