The time slot resources are used to transmit real-time data traffic. In this way, based on the real-time data traffic size and related path information (location information and data flow direction) of each branch network, time slots are divided for each branch network. Each branch network can start transmitting non-real-time data traffic based on its corresponding time slot resources after the real-time data traffic is transmitted.

The embodiment of the present application reduces resource waste and improves resource utilization while ensuring the real-time transmission of real-time data traffic in the industrial network, thereby improving the data transmission capacity of the industrial network.

[0058] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0059] Industrial networks are now widely used in a variety of fields, such as industrial automation, power electronics, the Internet of Things, and aerospace. In this field, ensuring the timely delivery of real-time data and guaranteeing the resource utilization of the industrial network are key factors in evaluating the real-time communication performance of industrial networks.

[0060] At present, in order to ensure that data with real-time requirements can be delivered on time, a scheduling scheme that uniformly divides time slots across the entire network is usually adopted. All devices in the industrial network follow the time slot division of the backbone network, and all devices uniformly control the transmission of real-time data traffic in the time slots scheduled for the backbone network. This will lead to resource waste and low resource utilization.

[0061] For example, an industrial network is divided into N (N is a positive integer greater than 1) branch networks, and one of the N branch networks serves as the backbone network. The real-time data traffic of the backbone network is usually greater than the real-time data traffic of other branch networks. The scheduling scheme of uniformly dividing time slots for the entire network refers to allocating time slot resources to the backbone network according to the size of the real-time data traffic of the entire network, also known as real-time time slots. In the real-time time slots, all devices are not allowed to send non-real-time data traffic. All devices in other branch networks need to uniformly control the transmission of real-time data traffic in the time slots scheduled for the backbone network. After the real-time data traffic of other branch networks is transmitted, they cannot directly start the transmission of non-real-time data traffic. Instead, they need to wait until all real-time data traffic in the time slot is transmitted before starting the transmission of non-real-time data traffic, resulting in resource waste and low resource utilization.

[0062] As the scale of industrial networks gradually increases, the resource waste caused by the above-mentioned scheduling scheme of uniformly dividing time slots across the entire network is becoming more and more serious, seriously affecting the data transmission capacity of industrial networks.

[0063] In view of this, embodiments of the present application provide a resource allocation method, apparatus, management node, industrial equipment, and storage medium, which can improve resource utilization of industrial networks and enhance the data transmission capabilities of industrial networks.

[0064] The resource allocation method provided in the embodiments of the present application can be applied to industrial networks. Industrial networks are divided into multiple branch networks, each of which can have a basic network topology, such as a linear or ring topology. Each branch network includes one or more nodes, which can also be called communication nodes, industrial devices, etc. Branch networks can also include management nodes, etc.

[0065] See also Figure 1 , is a schematic diagram of an exemplary implementation environment of a resource allocation method.

[0066] like Figure 1As shown in the figure, the industrial network includes 11 nodes (1, 2, 3, 4, 5, 2.1, 2.2, 2.3, 2.2.1, 4.1, and 4.2), each of which has data transmission and reception functions. Node 1 is a management node, while nodes 2, 2.2, and 4 are multi-port nodes with expansion capabilities. A multi-port node includes two basic ports and one or more expansion ports. Basic ports are used to connect to other nodes in the same branch network, while expansion ports are used to connect to the next branch network.

[0067] like Figure 1 As shown, the industrial network can be divided into four branch networks: branch network 1, branch network 2, branch network 3, and branch network 4. Branch network 1 containing the management node can also be called the backbone network. Branch network 1 extends branch network 2 through the expansion port at node 2, branch network 2 extends branch network 3 through the expansion port at node 2.2, and branch network 1 extends branch network 4 through the expansion port at node 4.

[0068] Each branch network can have real-time data traffic, and of course it can also have real-time data traffic. For each branch network, the resource allocation mechanism (or resource scheduling mechanism) must meet the requirements of timely delivery of real-time data traffic within the real-time time period and transmit as much non-real-time data traffic as possible.

[0069] Below, in conjunction with the drawings in the embodiments of this application, the technical solutions in the embodiments of this application are clearly and completely described. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0070] The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0071] In an exemplary embodiment, Figure 2 As shown, a resource allocation method is provided, which is described by taking the application of the method to a management node in an industrial network as an example, including the following steps 201 and 202:

[0072] Step 201 : determining the time slot resources of each branch network according to the location information of each branch network in the industrial network, the data volume of the real-time data flow, and the data flow direction.

[0073] Each branch network is divided according to the network topology of the industrial network. For example, the management node can obtain the network topology of the industrial network, which represents information such as the connection relationships between nodes in the industrial network. As described above, for a node, the basic port is used to connect to other nodes in the same branch network, and the extended port is used to connect to the next branch network. Therefore, the management node can determine each branch network by identifying whether each port of each node in the network topology is connected to other nodes.

[0074] In other possible implementations, the industrial network may be divided into branch networks by other devices, and the management node obtains the branch network division result from the other devices, thereby determining each branch network.

[0075] In the embodiment of the present application, the location information of the branch network is used to characterize the topological location of the branch network in the industrial network.

[0076] Optionally, for the backbone network (including the branch network of the management node) in each branch network, the node identifier of the management node is used to represent the location information of the branch network. For the non-backbone network in each branch network, the location information of the branch network can be represented by the node identifier of the node in the upper network to which the branch network is connected. For example, Figure 1 As shown, the location information of branch network 2 is represented by the node identifier of node 2, the location information of branch network 3 is represented by the node identifier of node 2.2, and the location information of branch network 4 is represented by the node identifier of node 4.

[0077] Optionally, the location information of the branch network can also be represented by the number of nodes between the node connecting the branch network to the upper network and the management node, etc. For example, the location information of branch network 2 is 1 node, the location information of branch network 3 is 3 nodes, and so on.

[0078] The data flow direction of the branch network represents the transmission path of the real-time data traffic of the branch network in the industrial network. For example, in the downstream direction, that is, when the real-time data traffic is distribution traffic, the path of the real-time data traffic of the branch network is sent by the control node to the last node in the branch network; for example, in the upstream direction, that is, when the real-time data traffic is aggregation traffic, the path of the real-time data traffic of the branch network is sent by the last node in the branch network to the management node.

[0079] For example, Figure 1As shown, in the downstream direction, the data flow of branch network 1 is from node 1 (management node) to node 5, the data flow of branch network 2 is from node 1 to node 2.3, the data flow of branch network 3 is from node 1 to node 2.2.1, and the data flow of branch network 4 is from node 1 to node 4.2; in the upstream direction, the data flow of branch network 1 is from node 5 to node 1, the data flow of branch network 2 is from node 2.3 to node 1, the data flow of branch network 3 is from node 2.2.1 to node 1, and the data flow of branch network 4 is from node 4.2 to node 1.

[0080] The data volume of the branch network's real-time data traffic refers to the size of the real-time data traffic that the branch network needs to transmit. For example, in the downlink direction, Figure 1 The data volume of the real-time data traffic of the branch network 1 shown is 150 bytes. In the upstream direction, the data volume of the real-time data traffic of the branch network 1 is 120 bytes, and so on.

[0081] In one possible implementation, for the downlink direction, the management node can calculate information such as the line transmission delay for each branch network when transmitting its real-time data traffic based on the location information and data flow direction of each branch network. Based on the data volume of the branch network's real-time data traffic, the management node can calculate the traffic transmission time required for the branch network to transmit the real-time data traffic. The management node can then calculate the downlink time slot resources allocated to the branch network based on the calculated traffic transmission time, line transmission delay, and other information. For the uplink direction, the management node can use a similar method to calculate the uplink time slot resources allocated to the branch network.

[0082] Exemplarily, a parameter generation model can also be pre-trained. During the training phase, the parameter generation model fully learns the mapping relationship between each sample location information, sample data volume, sample data flow direction and sample time slot resource location. After the training is completed, the management node inputs the location information of each branch network, the data volume of real-time data traffic, and data flow direction into the pre-trained parameter generation model, and the parameter generation model can then output the location of the time slot resource based on the learned mapping relationship.

[0083] Step 202: Allocate corresponding time slot resources to each branch network, and the time slot resources are used to transmit real-time data traffic.

[0084] After determining the time slot resources corresponding to each branch network, the management node allocates the corresponding time slot resources to each branch network. For example, the management node may send resource scheduling information including the time slot resources to each node in the branch network.

[0085] In this way, the embodiment of the present application combines the real-time data traffic size and related path information (location information and data flow direction) of each branch network to divide each branch network into time slots. Each branch network transmits data traffic according to its own time slot division. The start time and end time of the time slot resources in each branch network are independent. Each branch network can start transmitting non-real-time data traffic after the real-time data traffic is transmitted based on its corresponding time slot resources. This can avoid the situation where all devices in each branch network need to wait for all real-time data traffic in the time slot of the backbone network to be transmitted before starting to transmit non-real-time data traffic when each branch network adopts a scheduling scheme that uniformly divides time slots for the entire network, thereby causing resource waste and low resource utilization. The embodiment of the present application reduces resource waste and improves resource utilization while ensuring the real-time transmission of real-time data traffic in the industrial network, thereby improving the data transmission capacity of the industrial network.

[0086] In one embodiment, based on Figure 2 In the embodiment shown, the following exemplarily introduces a process in which the management node determines the time slot resources of each branch network according to the location information of each branch network in the industrial network, the data volume of the real-time data traffic, and the data flow direction.

[0087] See also Figure 3 , step 201 may include Figure 3 Steps 301 and 302 are shown:

[0088] Step 301: Determine the traffic transmission order of each branch network according to each location information.

[0089] In the embodiments of the present application, the traffic transmission order of each branch network can be configured based on the location information of each branch network. The traffic transmission order refers to the order in which real-time data traffic is transmitted between the branch networks. For example, the traffic transmission order is branch network 1 -> branch network 2 -> branch network 3 -> branch network 4. Branch networks in different topological locations in the industrial network have different corresponding traffic transmission orders.

[0090] Optionally, in the case where real-time data traffic is distribution traffic, the traffic transmission order is determined based on the first distance between each branch network and the traffic distribution node in the industrial network. The traffic distribution node can be, for example, a management node. The size of the first distance is positively correlated with the priority of the traffic transmission order, that is, the farther the branch network is from the traffic distribution node, the higher the priority of the traffic transmission order of the branch network. Data streams are sent from far to near, and the real-time data traffic transmission of branch networks that are farther away from the traffic distribution node is started first. Branch networks that are farther away from the traffic distribution node may transmit real-time data traffic in parallel with branch networks that are closer to the traffic distribution node, thereby improving resource utilization and transmission rate.

[0091] like Figure 1 As shown, the first distance between branch network 1 and the traffic distribution node (management node 1) is 0, the first distance between branch network 2 and the traffic distribution node (management node 1) is 1 node apart, the first distance between branch network 3 and the traffic distribution node (management node 1) is 3 nodes apart, and the first distance between branch network 4 and the traffic distribution node (management node 1) is 3 nodes apart. Then, in the downstream direction, branch network 4 and branch network 3 have the highest priority, followed by branch network 2, and finally branch network 1. For example, in the downstream direction, the traffic transmission order is branch network 4->branch network 3->branch network 2->branch network 1.

[0092] Optionally, in the case where the real-time data traffic is converged traffic, the traffic transmission order is determined according to the second distance between each branch network and the convergence node in the industrial network. Figure 1 For node 2 shown, the size of the second distance is negatively correlated with the priority of the traffic transmission order, that is, the farther the branch network is from the aggregation node, the lower the priority of the traffic transmission order of the branch network. Data streams are sent from near to far, and the real-time data traffic transmission of the branch network closer to the aggregation node is started first. The real-time data traffic transmitted by the branch network farther away from the aggregation node is completed first, and other branch networks can start transmitting real-time data traffic as soon as possible, thereby improving the transmission rate.

[0093] like Figure 1 As shown, exemplarily, in the uplink direction, the traffic transmission order is branch network 1 -> branch network 2 -> branch network 3 -> branch network 4.

[0094] Step 302 : determining the time slot resources of each branch network according to the transmission sequence of each flow, each location information, each data volume, and each data flow direction.

[0095] After the management node determines the traffic transmission order for each branch network based on the location information, it then determines the time slot resources for each branch network based on the traffic transmission order and the location information, data volume, and data flow direction in the above embodiments. By configuring the traffic transmission order for each branch network, the transmission rate of real-time data traffic can be improved.

[0096] Next, a process of determining the time slot resources of each branch network by the management node according to the transmission sequence of each flow, each location information, each data volume, and each data flow direction is exemplarily introduced.

[0097] See 4, step 302 may include Figure 4 Steps 401 to 404 are shown as follows:

[0098] Step 401: Determine the line transmission delay corresponding to each branch network according to each location information and each data flow direction.

[0099] Different branch networks have different topological locations within the industrial network, and their distances from traffic distribution nodes (such as management nodes) or aggregation nodes also vary. Consequently, line transmission latency also varies. Line transmission latency can be understood as the time it takes for real-time data traffic from a branch network to travel across the lines outside the branch network while being transmitted within the industrial network.

[0100] In the embodiment of the present application, the management node determines the line transmission delay corresponding to each branch network based on each location information and each data flow direction.

[0101] Exemplarily, in the downlink direction, the management node can obtain the distance between the branch network and the traffic distribution node (such as the management node) based on the location information and the data flow direction, and then multiply the distance by the line delay corresponding to the unit distance to obtain the line transmission delay corresponding to the branch network; optionally, the distance can also be expressed by the number of nodes between the branch network and the traffic distribution node. The line transmission delay corresponding to each node is fixed. The number of nodes is multiplied by the line transmission delay corresponding to the node to obtain the line transmission delay corresponding to the branch network, and so on. There is no limitation on the method of determining the line transmission delay corresponding to each branch network.

[0102] For example, in the uplink direction, similar to the downlink direction, the management node can obtain the distance between the branch network and the aggregation node based on each location information and each data flow direction, and then obtain the line transmission delay corresponding to the branch network based on the distance.

[0103] Step 402, based on the transmission order of each flow, each data volume and each data flow direction, determine the data flow size that each branch network needs to wait for transmission, and determine the corresponding sending waiting time of each branch network based on the data flow size and the transmission rate of each branch network.

[0104] The amount of data traffic that a branch network needs to wait for transmission refers to the amount of real-time data traffic that a branch network needs to wait for transmission from other branch networks before transmitting its own real-time data traffic.

[0105] For example, in the downstream direction, the real-time data traffic of all other branch networks whose traffic transmission order precedes that of the branch network can be used as the amount of data traffic that the branch network needs to wait for transmission. In the upstream direction, the real-time data traffic of several branch networks whose traffic transmission order precedes that of the branch network and that need to pass through the convergence node can be used as the amount of data traffic that the branch network needs to wait for transmission.

[0106] After determining the data traffic size that each branch network needs to wait for transmission, the management node determines the corresponding sending waiting time of each branch network according to the data traffic size and the transmission rate of each branch network.

[0107] Optionally, when the real-time data traffic is distribution traffic, for each branch network, according to the transmission order of each traffic, the sending time of all real-time data traffic before the branch network is determined as the sending waiting time. The sending time of the real-time data traffic can be calculated through the data traffic size and the transmission rate of each branch network.

[0108] Optionally, when the real-time data traffic is converged traffic, for each branch network, according to the transmission order of each traffic, the sending time of all real-time data traffic that needs to pass through the convergence node in the industrial network and whose traffic transmission order is before the branch network will be determined as the sending waiting time. The sending time of the real-time data traffic can be calculated through the data traffic size and the transmission rate of each branch network.

[0109] Step 403: Determine the traffic transmission time corresponding to each branch network according to each data volume and each transmission rate.

[0110] The management node can multiply the data volume by the corresponding transmission rate to obtain the corresponding traffic transmission time of the branch network.

[0111] Step 404 : For each branch network, determine the time slot resources of the branch network according to the line transmission delay, sending waiting time, and traffic transmission time corresponding to the branch network.

[0112] Exemplarily, the management node may calculate the start time of the time slot resource by using the following formula 1:

[0113] T1_x=T_Delay1 + T_Delay2 Formula 1

[0114] Among them, T1_x is the start time of the time slot resource, T_Delay1 is the line transmission delay calculated in step 401, and T_Delay2 is the sending waiting time calculated in step 402. That is, the management node adds the line transmission delay and the sending waiting time to obtain the start time of the time slot resource.

[0115] The management node can calculate the end time of the time slot resource using the following formula 2:

[0116] T2_x= T1_x+ T_Data + T_Delay Formula 2

[0117] Among them, T2_x is the end time of the time slot resource, T_Data is the traffic transmission time calculated in step 403, and T_Delay is the line transmission delay of the branch network itself. That is, the management node adds the start time of the time slot resource to the line transmission delay and traffic transmission time of the branch network to obtain the end time of the time slot resource.

[0118] In the upstream direction, the management node determines the branch network's uplink time slot resources based on the branch network's corresponding line transmission delay, send wait time, and traffic transmission time in the upstream direction. In the downstream direction, the management node determines the branch network's downlink time slot resources based on the branch network's corresponding line transmission delay, send wait time, and traffic transmission time in the downlink direction. Each branch network uses different time slot allocations for different data flow directions to improve resource utilization.

[0119] The following examples illustrate the resource allocation results of the embodiment of the present application. Figure 1 An exemplary scheduling parameter table of an industrial network is shown.

[0122] The management node first obtains the scheduling parameters in Table 1 except the start time and end time of the time slot resources, such as the location information of each branch network, the data volume of real-time data traffic, the data flow direction and the transmission rate, and then calculates the start time and end time of the uplink time slot resources and the start time and end time of the downlink time slot resources through the implementation method of any of the above embodiments, and adds them to Table 1 to obtain a complete scheduling parameter table.

[0123] The management node configures the scheduling parameter table to each branch network, and each branch network controls the transmission of real-time data traffic according to the time slot allocated in the scheduling parameter table.

[0124] See also Figure 5 , Figure 5 is a schematic diagram of an exemplary time slot division of each branch network, such as Figure 5 As shown, while ensuring that real-time data traffic is interacted on time within the cycle time, the transmission of non-real-time data traffic can begin after the real-time data traffic is sent. The embodiment of the present application can greatly increase the transmission time slot of non-real-time data traffic, improve resource utilization, and enhance the data transmission capability of the industrial network.

[0125] In one embodiment, based on any of the above embodiments, the following is an exemplary introduction to the way in which the management node determines each branch network. Figure 6 ,include Figure 6 Step 601 and step 602 are shown:

[0126] Step 601: Receive node topology information sent by each node in the industrial network. The node topology information includes device connection information of each port of the node and the port type of each port.

[0127] Device connection information can indicate which port is connected to which port of which node, or whether the port is not connected to any port. Port types include basic ports and extended ports. Basic ports are used to connect to other nodes in the same branch network, and extended ports are used to connect to the next branch network device connection information.

[0128] Step 602: Determine the network topology based on the connection information of each device and the type of each port, and determine each branch network based on the network topology.

[0129] The management node can obtain the network topology based on the connection information of each device. In the network topology, each branch network can be divided according to the port type of the port in the connected state of each node.

[0130] In the embodiment of the present application, the branch network can be a basic topology structure such as a linear or ring structure, and of course it can also be other topologies, which are not limited here.

[0131] By dividing the branch network, combining the real-time data traffic size and related path information (location information and data flow direction) of each branch network, each branch network is divided into time slots. Each branch network can start transmitting non-real-time data traffic after the real-time data traffic is transmitted based on its corresponding time slot resources. The embodiment of the present application reduces resource waste and improves resource utilization while ensuring the real-time transmission of real-time data traffic in the industrial network, thereby improving the data transmission capacity of the industrial network.

[0132] In one embodiment, a resource allocation method is provided, which is applied to a node (or communication node or industrial equipment) in any branch network of an industrial network. The method includes: receiving resource allocation information sent by a management node in the industrial network.

[0133] The resource allocation information is used to indicate the time slot resources allocated by the management node for the current branch network. The time slot resources are obtained by the management node through resource allocation according to any of the implementation methods in the above embodiments.

[0134] In one embodiment, a resource allocation method is provided, which is applied in an industrial network and includes the following steps:

[0135] In step A1, a management node receives node topology information sent by each node in the industrial network. The node topology information includes device connection information of each port of the node and a port type of each port.

[0136] In step A2, the management node determines a network topology based on the connection information of each device and the type of each port, and determines each branch network based on the network topology.

[0137] In step A3, the management node determines the traffic transmission order of each branch network according to the location information of each branch network.

[0138] Among them, when the real-time data traffic is distribution traffic, the management node determines the traffic transmission order based on the first distance between each branch network and the traffic distribution node in the industrial network. The size of the first distance is positively correlated with the priority of the traffic transmission order.

[0139] When the real-time data traffic is converged traffic, the management node determines the traffic transmission order based on the second distance between each branch network and the convergence node in the industrial network. The size of the second distance is negatively correlated with the priority of the traffic transmission order.

[0140] In step A4, the management node determines the line transmission delay corresponding to each branch network according to the location information and the data flow direction of each branch network.

[0141] In step A5, the management node determines the size of the data flow that each branch network needs to wait for transmission based on the transmission order of each flow, the data volume of the real-time data flow of each branch network, and the data flow direction, and determines the corresponding sending waiting time of each branch network based on the size of each data flow and the transmission rate of each branch network.

[0142] In the case where the real-time data traffic is distributed traffic, for each branch network, the management node determines the sending time of all real-time data traffic before the branch network as the sending waiting time according to the transmission order of each traffic.

[0143] When the real-time data traffic is converged traffic, for each branch network, the management node will determine the sending time of all real-time data traffic that needs to pass through the convergence node in the industrial network and whose traffic transmission order is before the branch network as the sending waiting time based on the transmission order of each traffic.

[0144] In step A6, the management node determines the traffic transmission time corresponding to each branch network according to the data volume and the transmission rate of each branch network.

[0145] In step A7, for each branch network, the management node determines the time slot resources of the branch network according to the line transmission delay, sending waiting time, and traffic transmission time corresponding to the branch network.

[0146] The management node adds the line transmission delay and the sending waiting time to obtain the start time of the time slot resource; the management node adds the start time to the line transmission delay of the branch network and the traffic transmission time to obtain the end time of the time slot resource.

[0147] In step A8, the management node allocates corresponding time slot resources to each branch network, and the time slot resources are used to transmit real-time data traffic.

[0148] In step A9, the industrial device receives resource allocation information sent by the management node in the industrial network.

[0149] The resource allocation information is used to indicate the time slot resources allocated by the management node to the current branch network.
