DETAILED DESCRIPTION

[0076] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0077] In this disclosure, expressions such as "first" and "second" do not limit the quantity or order of execution, and expressions such as "first" and "second" do not necessarily mean different. Unless otherwise specified, " / " means "or" or "and / or." For example, A / B can mean A or B. "And / or" in this document is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, "A and / or B" can mean: only A, only B, and A and B.

[0078] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this disclosure are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0079] C2D communication applies mobile communication technology to industrial control systems, enabling controller-to-device communication between industrial controllers and industrial I / O devices. Industrial control systems consist of industrial controllers, multiple industrial I / O devices, and gateways. Industrial controllers, including programmable logic controllers (PLCs), operate in a cyclical scanning mode, transmitting C2D data in a specific communication cycle. During each C2D communication cycle, the PLC must output a large number of data packets to the vast number of I / O devices on the industrial site.

[0080] The process of C2D data transmission between PLC and industrial I / O devices is as follows: PLC encapsulates the I / O data to be transmitted into multiple IP data packets and outputs them to each corresponding I / O device through the communication network within one communication cycle. During the operation of PLC, the above operations are repeated in each communication cycle until the data transmission is completed.

[0081] For example, FIG1 is a schematic diagram of an application scenario of a method for data aggregation and transmission provided by an embodiment of the present disclosure. As shown in FIG1 , the application scenario of the method for data aggregation and transmission includes a PLC industrial controller 11, a gateway 12, multiple I / O devices 13, and multiple data packets 14. The PLC encapsulates the I / O data to be transmitted into multiple data packets, and sends each data packet from the cloud platform to the gateway device at the industrial site during each communication cycle. The gateway device then sends the data packets encapsulated from each I / O data to the corresponding I / O device, so that each I / O device receives the required data and performs subsequent industrial operations based on the data.

[0082] However, since the I / O data is encapsulated into multiple data packets, each data packet includes header data and payload data, wherein the header data occupies a large number of bytes of the data packet and the payload data only occupies a small number of bytes. Therefore, in the process of transmitting multiple data packets, a large amount of network bandwidth resources are used to transmit the header data of each data packet, and the contribution rate of network bandwidth resources to the transmission of payload data in the data packet is low, resulting in a waste of network bandwidth resources, and the payload data transmitted by a certain network bandwidth resource is limited, which reduces the data transmission efficiency; in addition, the communication cycle of C2D data transmission is short, and all data packets need to be transmitted to each I / O device at the other end within one communication cycle. Therefore, a large number of data packets are transmitted in the network at the same time period, causing congestion in the communication network, and a large number of data packets are easily affected by fluctuations in network quality, which is likely to cause some data packets to arrive at each I / O device late, reducing data transmission efficiency while also reducing the reliability and stability of data transmission.

[0083] The present disclosure controls the required I / O devices through the PLC to access the deaggregation module of the industrial control system to complete the connectivity of the C2D data transmission channel, and then obtains the information of N I / O devices from the PLC through the aggregation module, and generates deaggregation configuration information and aggregation configuration information according to the device information, and transmits the deaggregation configuration information to the deaggregation module through the network. The aggregation module is configured according to the aggregation configuration information and then reads the I / O data, and the read I / O data is combined to generate an aggregation message, and the aggregation message is transmitted to the deaggregation module through the network, so that the deaggregation module of the industrial control system configures the deaggregation module according to the received deaggregation configuration information and the interface information of each connected I / O device, and parses the received aggregation message after the configuration is completed to generate each I / O data, and determines the I / O device interface corresponding to each I / O data through the configuration result of the deaggregation module, thereby determining the corresponding I / O device, and realizing the transmission of the I / O data by calling the corresponding device interface channel. By aggregating each I / O data into an aggregate message for transmission, the proportion of header data bytes is reduced, the contribution of network resources to load data is increased, and transmission efficiency is improved. Moreover, by transmitting only one aggregate message in the network, network congestion and the impact of network quality fluctuations are reduced, thereby improving the stability and reliability of data transmission.

[0084] The data aggregation and transmission method provided in the present disclosure is intended to at least solve the above technical problems.

[0085] The following exemplary embodiments describe in detail the technical solutions of the present disclosure and how they solve the aforementioned technical problems. The following exemplary embodiments may be combined with one another, and identical or similar concepts or processes may not be described in detail in certain embodiments. The following embodiments of the present disclosure are described in conjunction with the accompanying drawings.

[0086] The data aggregation and transmission method disclosed in the present invention can be used in an industrial control system. The execution subject of the method can be a device for data aggregation and transmission, or an industrial control system that runs a device for data aggregation and transmission. The following description takes an industrial control system that runs a device for data aggregation and transmission as an example, wherein the industrial control system includes a PLC, an aggregation module, a deaggregation module and an I / O device. This embodiment involves an example process in which a PLC industrial controller transmits aggregated data to an I / O device through an aggregation module and a deaggregation module.

[0087] FIG2 is a schematic diagram of the structure of a method for data aggregation and transmission provided by an embodiment of the present disclosure. As shown in FIG2 , the structure includes a PLC industrial controller (abbreviated as “PLC”) 11, a gateway 12, an aggregation module 15, a deaggregation module 16, a plurality of I / O devices 13, and an aggregation message 14. The PLC sends the I / O data to be transmitted to the aggregation module. After the aggregation module obtains all the I / O data, it combines the various I / O data to generate an aggregation message, and transmits the aggregation message to the deaggregation module through the network and the gateway. After receiving the aggregation message, the deaggregation module parses the aggregation message and generates various independent I / O data. The deaggregation module then sends the various I / O data to the corresponding I / O devices, so that each I / O device receives the required data and performs subsequent industrial operations based on the data.

[0088] FIG3 is a flow chart of a method for data aggregation and transmission provided by an embodiment of the present disclosure. As shown in FIG3 , the application scenario provided by this embodiment is based on the application scenario shown in FIG2 . The method for data aggregation and transmission includes the following steps:

[0089] S301. The PLC outputs the information of the I / O device to the aggregation module.

[0090] For example, the aggregation module reads I / O device information from the PLC through the Mc interface, and the PLC outputs information about N I / O devices to the aggregation module through the Mc interface. As shown in Figure 6, the Mc interface is the interface for transmitting I / O device information between the aggregation module and the PLC, where N is a positive integer.

[0091] In some embodiments, the I / O device information includes the number of I / O devices, I / O device identification, the number of I / O data bytes sent to the I / O device and the sending cycle, and the memory address where each of the above I / O data is stored in the PLC.

[0092] S302: The aggregation module generates aggregation configuration information and de-aggregation configuration information.

[0093] For example, the aggregation module receives information from N I / O devices and generates aggregation configuration information for the aggregation module and deaggregation configuration information for the deaggregation module based on the information from the N I / O devices. The aggregation configuration information includes the aggregation order of each I / O data, the memory address of each I / O data, and the aggregation period. The deaggregation configuration information includes the aggregation order of each I / O data and the starting address of each I / O data.

[0094] In some embodiments, the aggregation module determines the aggregation period of data transmission between the PLC and the I / O device, the aggregation order of each I / O data, and the memory address of each I / O data stored in the PLC based on the information of N I / O devices, and calculates the starting address of each I / O data in the aggregation message based on the aggregation order of each I / O data and the memory address of each I / O data stored in the PLC, wherein the aggregation message is the carrier for transmitting data between the PLC and the I / O device.

[0095] In some embodiments, the aggregation module generates aggregation configuration information based on the aggregation order of each I / O data, the memory address of each I / O data, and the aggregation period; and generates de-aggregation configuration information based on the aggregation order of each I / O data and the starting address of each I / O data.

[0096] S303: The aggregation module performs aggregation configuration according to the aggregation configuration information.

[0097] For example, the aggregation module performs aggregation configuration on the reading function of the aggregation module according to the generated aggregation configuration information, so that the aggregation module after aggregation configuration can perform related data transmission tasks based on the aggregation configuration information.

[0098] S304: The aggregation module sends de-aggregation configuration information to the de-aggregation module.

[0099] For example, the aggregation module outputs the deaggregation configuration information through the Mn interface, so that the deaggregation configuration information is transmitted to the deaggregation module through the communication network. As shown in Figure 6, the Mn interface is the interface for transmitting the deaggregation configuration information between the aggregation module and the communication network.

[0100] S305. The de-aggregation module performs de-aggregation configuration according to the de-aggregation configuration information.

[0101] For example, the de-aggregation module receives the de-aggregation configuration information sent by the aggregation module, and performs de-aggregation configuration on the de-aggregation module according to the de-aggregation configuration information.

[0102] S306: The aggregation module reads the I / O data and generates an aggregation message.

[0103] For example, after the aggregation module completes the aggregation configuration for the read function based on the aggregation configuration information, it uses the aggregation configuration results to read the individual I / O data from the PLC. The aggregation module combines the read I / O data based on the aggregation configuration results to generate an aggregation frame. The aggregation configuration results include the aggregation period for this data transmission, the memory address of each I / O data point, and the order in which the I / O data points are aggregated.

[0104] In one exemplary embodiment, the aggregation module determines whether the aggregation period in the aggregation configuration results is within the current aggregation period. During the aggregation period, the aggregation module reads the I / O data from the PLC based on the memory address of each I / O data. The aggregation module then combines the read I / O data in sequence according to the aggregation order of the I / O data in the aggregation configuration results, generates an aggregation frame, and then adds the corresponding header information to the aggregation frame to encapsulate it into an aggregated message. The header information of the aggregated message does not include the frame header used for parsed data.

[0105] For example, FIG4 is a schematic diagram of the structure of an aggregate message provided by an embodiment of the present disclosure. As shown in FIG4 , the aggregate message includes an Ethernet frame header, an IP header, a TCP header, N I / O data, and an FCS. The aggregation module reads N I / O data from the PLC, combines the above N I / O data into an aggregate frame, adds an Ethernet frame header, an IP header, and a TCP header before the first I / O data in the aggregate frame, and adds a frame check sequence (FCS) after the last I / O data in the aggregate frame, thereby encapsulating and generating an aggregate message.

[0106] In some embodiments, the aggregate frame is an application layer data frame that aggregates multiple small-sized I / O data into one frame. The aggregation module can transmit the aggregate frame to the deaggregation module based on the TCP / IP (Transmission Control Protocol / Internet Protocol) protocol.

[0107] In some embodiments, as shown in Figure 6, the aggregation module reads individual I / O data from the PLC via the Ac interface, generates an aggregated message based on the individual I / O data, and then sends the aggregated message to the deaggregation module via the An interface. The Ac interface is the interface between the aggregation module and the PLC for transmitting individual I / O data, while the An interface is the interface between the aggregation module and the deaggregation module for transmitting aggregated messages.

[0108] S307: The aggregation module sends the aggregation message to the deaggregation module.

[0109] For example, the aggregation module encapsulates the aggregation frame into an aggregation message and then outputs the aggregation message to the deaggregation module.

[0110] S308: The de-aggregation module parses the aggregated message to generate various I / O data.

[0111] For example, after the de-aggregation configuration is completed, the de-aggregation module receives the aggregate message sent by the aggregation module and parses the aggregate message to generate restored N I / O data.

[0112] S309: The de-aggregation module sends each I / O data to the I / O device.

[0113] For example, the de-aggregation module sends N I / O data to corresponding I / O devices.

[0114] In the data transmission method provided by the embodiment of the present disclosure, the information of each I / O device is obtained from the PLC through the aggregation module, and the aggregation configuration information of the aggregation module and the deaggregation configuration information of the deaggregation module are generated according to the I / O information, and the reading function in the aggregation module is configured according to the aggregation configuration information. After the configuration is completed, the I / O data is read from the PLC, and the read I / O data are combined to generate an aggregation frame, and the aggregation message is generated after encapsulation and sent to the deaggregation module. In addition, the aggregation module sends the deaggregation configuration information to the deaggregation module, so that the deaggregation module performs deaggregation configuration based on the deaggregation configuration information, and parses and splits the aggregate message into N I / O data after receiving the aggregate message and sends it to the corresponding device, thereby avoiding transmission delay caused by multiple data packets being transmitted simultaneously in the network within an aggregation cycle, improving data transmission reliability and stability, and increasing the network's contribution to data transmission by encapsulating it into an aggregate message, and then splitting it after the aggregate message arrives, and accurately sending it to each device, thereby improving data transmission efficiency.

[0115] FIG5 is a flow chart of a method for data aggregation and transmission provided by an embodiment of the present disclosure. As shown in FIG5 , the application scenario provided by this embodiment is based on the application scenario shown in FIG2 , and the method for data aggregation and transmission includes S501 to S509 .

[0116] S501. PLC outputs control instructions to the deaggregation module.

[0117] For example, the user inputs the relevant information of the required N I / O devices into the PLC, uploads the control instructions related to each I / O device to the PLC instance, and outputs the control instructions to the deaggregation module, so that the PLC controls the required N I / O devices according to the control instructions and communicates with the deaggregation module.

[0118] S502: The de-aggregation module connects to the required I / O device and obtains the I / O device configuration information.

[0119] For example, the deaggregation module receives the control instructions output by the PLC, and connects the indicated I / O devices to the deaggregation module according to the control instructions, and scans the interfaces of the connected I / O devices, and obtains the configuration information of each I / O device by identifying the interfaces of all connected I / O devices.

[0120] In some embodiments, the I / O device configuration information includes interface information.

[0121] S503: The aggregation module sends de-aggregation configuration information to the de-aggregation module.

[0122] For example, after the aggregation module obtains information of each I / O device, generates deaggregation configuration information according to the information of each I / O device, and sends the deaggregation configuration information to the deaggregation module, the deaggregation module receives the deaggregation configuration information sent by the aggregation module.

[0123] In some embodiments, the de-aggregation configuration information includes an aggregation order of each I / O data and a starting address of each I / O data.

[0124] S504: The deaggregation module performs deaggregation configuration according to the deaggregation configuration information and the I / O device configuration information.

[0125] For example, the deaggregation module receives the deaggregation configuration information sent by the aggregation module. The deaggregation module generates the correspondence between the data address and the device interface based on the aggregation order of each I / O data in the deaggregation configuration information and the starting address of each I / O data and the various interface information in the I / O device configuration information, and configures the parsing function of the deaggregation module according to the correspondence between the data address and the device interface.

[0126] In an exemplary embodiment, the deaggregation module determines the data address of each I / O data (each frame) in the aggregated message and / or the combined arrangement order of each frame in the aggregated frame based on the aggregation order of each I / O data and the starting address of each I / O data in the deaggregation configuration information, and matches the interface information of each I / O device indicated in the I / O device configuration information with the determined data address of each frame, thereby determining the transmission interface corresponding to the data address of each frame, and then determining the I / O device corresponding to the data address of each frame.

[0127] In some embodiments, as shown in FIG4 , the aggregate frame includes N I / O data frames, where each data frame corresponds to a data address.

[0128] S505: The de-aggregation module waits for input of the aggregated message.

[0129] For example, after the deaggregation module completes the configuration of the parsing function based on the deaggregation configuration information, it waits for the input of the aggregation message. The aggregation message is obtained in the following manner: the aggregation module generates aggregation configuration information based on the information of N I / O devices, performs aggregation configuration based on the aggregation configuration information, reads N I / O data based on the memory address of each I / O data in the aggregation configuration result, combines the read N I / O data based on the aggregation order of each I / O data in the aggregation configuration result to generate an aggregation message, and outputs the aggregation message to the deaggregation module; and the aggregation configuration information includes the aggregation order of each I / O data, the memory address of each I / O data and the aggregation period.

[0130] S506: The aggregation module sends the aggregation message to the deaggregation module.

[0131] For example, after the aggregation module reads N I / O data and combines and encapsulates them to generate an aggregation message, and sends the aggregation message to the de-aggregation module, the de-aggregation module is triggered to receive the aggregation message sent by the aggregation module.

[0132] S507: The de-aggregation module parses the aggregated message and generates various I / O data.

[0133] For example, after receiving the aggregation message, the deaggregation module parses the aggregation message according to the starting addresses of the N I / O data in the deaggregation configuration result and the aggregation order of each I / O data, thereby splitting and generating N I / O data.

[0134] S508: The deaggregation module calls the I / O device to write into the channel.

[0135] For example, the deaggregation module determines the device interfaces corresponding to N I / O data through the correspondence between the data addresses and device interfaces in the deaggregation configuration results, and calls the write channels corresponding to N I / O data and / or each device interface according to the device interfaces corresponding to each I / O data, so that each I / O data is transmitted to each I / O device through each I / O device write channel.

[0136] In some embodiments, the de-aggregation module generates a write channel corresponding to each I / O device by identifying each connected I / O device, so as to be called by the de-aggregation module when performing I / O data transmission.

[0137] S509: The de-aggregation module sends each I / O data to the I / O device.

[0138] For example, the de-aggregation module sends N I / O data to corresponding I / O devices by calling the determined write channels.

[0139] In an exemplary embodiment, as shown in Figure 7, the deaggregation module obtains I / O device configuration information through the Mp interface and deaggregation configuration information through the Mg interface. Based on the device configuration information and deaggregation configuration information, the module generates a correspondence between data addresses and device interfaces. Based on this correspondence, the module configures deaggregation for the parsing function within the deaggregation module through the Md interface. After configuration is complete, the deaggregation module receives aggregated messages sent by the aggregation module through the Dg interface. After parsing the aggregated messages, the module invokes the write channels of each I / O device through the Dp interface and sends the corresponding I / O data through each write channel. The Mp interface is the interface through which the deaggregation module obtains I / O device configuration information; the Mg interface is the interface through which the deaggregation module obtains deaggregation configuration information transmitted by the aggregation module over the network; the Md interface is the interface through which the deaggregation module configures deaggregation for the parsing function; the Dg interface is the interface through which the deaggregation module obtains aggregated messages sent by the aggregation module over the network; and the Dp interface is the interface through which the deaggregation module invokes the write channels of each I / O device.

[0140] In the data transmission method provided by the embodiment of the present disclosure, the deaggregation module receives the deaggregation configuration information and the aggregation message sent by the aggregation module, and obtains the I / O device configuration information by scanning each I / O device, generates the correspondence between the data address and the device interface according to the interface information indicated by the I / O device configuration information and the deaggregation configuration information, and configures the deaggregation module according to the correspondence, and parses the received aggregation message according to the starting address of each I / O data in the deaggregation configuration information to split out each I / O data, and determines the interface corresponding to each I / O data through the correspondence between the data address and the device interface, thereby calling the write channel corresponding to each interface, so that the I / O data is sent to the corresponding I / O device through the corresponding write channel, so that after the aggregation module transmits an aggregation message to the device side through the network, the deaggregation module on the device side can also split the aggregation message according to demand and output it accurately to each device, thereby improving the accuracy and reliability of data transmission.
