The preset format can be SenML (SensorMarkup Language, sensor markup language) format, and the corresponding first data packet is SenML data pack.

具体地，各个设备数字孪生体可以根据预设传输协议和预设通信模式与对应的物理设备建立通信连接。例如，Print-DT与锡膏印刷机建立通信连接，QInsp-DT与质检设备建立通信连接，Cam-DT与辅助质检IP相机建立通信连接。其中，预设传输协议可以是IoT(Internet of Things，物联网)传输协议，如ModBus(一种工业通信协议)协议、MQTT(Message Queue Telemetry Transport，消息队列遥测传输)协议等，预设通信模式可以是Restful(Representational State Transfer，表现层状态转化)模式、发布-订阅模式等，本公开对传输协议和通信模式不做具体限定。Specifically, each device digital twin can establish a communication connection with the corresponding physical device according to a preset transmission protocol and a preset communication mode. For example, Print-DT establishes communication connection with solder paste printing machine, QInsp-DT establishes communication connection with quality inspection equipment, and Cam-DT establishes communication connection with auxiliary quality inspection IP camera. Wherein, the preset transmission protocol can be IoT (Internet of Things, Internet of Things) transmission protocol, such as ModBus (an industrial communication protocol) protocol, MQTT (Message Queue Telemetry Transport, message queue telemetry transmission) protocol, etc., and the preset communication mode It may be a Restful (Representational State Transfer, presentation layer state transformation) mode, a publish-subscribe mode, etc. The present disclosure does not specifically limit the transmission protocol and communication mode.

举例而言，对于设备数字孪生体为Print-DT，对应的物理设备为锡膏印刷机。Print-DT接收到锡膏印刷机传入的原始数据后，可以将原始数据转化为SenML数据包，SenML数据包中可以包括时间戳“t”、测量值“v”、设备名称“n”和数据单元“u”等信息。例如，一种SenML数据包为[{“n”:“urn:dev:10e1033”,“t”:0,“u”:“V”,“v”:120.1}]，表示物理设备的名称为10e1033，时间戳为0，数据单元为V，测量值为120.1。For example, the digital twin of the device is Print-DT, and the corresponding physical device is a solder paste printing machine. After Print-DT receives the raw data from the solder paste printing machine, it can convert the raw data into SenML data packets. The SenML data packets can include timestamp "t", measured value "v", device name "n" and Data unit "u" and other information. For example, a SenML packet is [{"n":"urn:dev:10e1033", "t":0, "u":"V", "v":120.1}], indicating that the name of the physical device is 10e1033, the timestamp is 0, the data unit is V, and the measured value is 120.1.

各个设备数字孪生体将对应的物理设备传入的原始数据转化成SenML数据包后，可以将SenML数据包发送至设备数字孪生体管理模块，以通过设备数字孪生体管理模块增强SenML数据包。本公开实施例中，基于设备数字孪生体与物理设备的虚实交互，可以实现设备数字孪生体管理模块与物理设备的互联互通，便于后续实现对工业物联网系统内各物理设备的智能化控制。After the digital twin of each device converts the raw data imported by the corresponding physical device into a SenML data packet, the SenML data packet can be sent to the device digital twin management module to enhance the SenML data packet through the device digital twin management module. In the embodiment of the present disclosure, based on the virtual-real interaction between the equipment digital twin and the physical equipment, the interconnection and intercommunication between the equipment digital twin management module and the physical equipment can be realized, which facilitates subsequent intelligent control of each physical equipment in the industrial Internet of Things system.

在步骤S220中，所述设备数字孪生体管理模块利用网络控制器下发的第一流量管理规则对所述第一数据包进行数据扩展，得到第二数据包。In step S220, the device digital twin management module uses the first traffic management rule issued by the network controller to perform data expansion on the first data packet to obtain a second data packet.

一种示例实施方式中，系统数字孪生集管理模块可以将设备数字孪生体聚合至新激活的系统数字孪生集中。然后，网络控制器根据系统数字孪生集中设备数字孪生体的服务质量参数初始化第一流量管理规则，并将第一流量管理规则下发至网络控制代理执行该规则。其中，设备数字孪生体的服务质量参数是指设备数字孪生体的QoS要求，QoS要求中的参数可以至少包括pck_loss_rate(丢包率)、latency(最大延时)和priority(优先级)。需要说明的是，该示例中的设备数字孪生体为新激活的设备数字孪生体，如Print-DT、QInsp-DT和Cam-DT等。In an example implementation, the system digital twin set management module can aggregate the equipment digital twin into the newly activated system digital twin set. Then, the network controller initializes the first traffic management rule according to the quality of service parameters of the digital twin of the system digital twin centralized device, and sends the first traffic management rule to the network control agent to execute the rule. Among them, the QoS parameter of the device digital twin refers to the QoS requirement of the device digital twin, and the parameters in the QoS requirement may include at least pck_loss_rate (packet loss rate), latency (maximum delay) and priority (priority). It should be noted that the device digital twins in this example are newly activated device digital twins, such as Print-DT, QInsp-DT, and Cam-DT.

系统数字孪生集管理模块发现新激活的各个设备数字孪生体时，可以存储各个设备数字孪生体的网络位置、能力等信息。技术人员通过与系统数字孪生集管理模块进行交互，可以激活一个系统数字孪生集。根据实际生产需求，激活的系统数字孪生集中可以是空集，也可以包括其它设备数字孪生体，本公开对此不做限定。例如，在SMT生产系统中，激活的系统数字孪生集为SMT产线数字孪生集S-DT-smt，可以根据保证系统正常运行的设备最小化准则将Print-DT、QInsp-DT纳入S-DT-smt中。同时，系统数字孪生集管理模块还可以提供S-DT-smt中各个设备数字孪生体的QoS要求，如表1所示：When the system digital twin set management module discovers newly activated digital twins of each device, it can store information such as the network location and capabilities of each device digital twin. A technician can activate a system digital twin set by interacting with the system digital twin set management module. According to actual production requirements, the activated system digital twin set may be an empty set, or may include other equipment digital twins, which is not limited in this disclosure. For example, in the SMT production system, the activated system digital twin set is the SMT production line digital twin set S-DT-smt, and Print-DT and QInsp-DT can be incorporated into S-DT according to the equipment minimization criteria to ensure the normal operation of the system -smt. At the same time, the system digital twin set management module can also provide the QoS requirements of each device digital twin in S-DT-smt, as shown in Table 1:

表1Table 1

Print-DT流量QoS要求QoS requirements for Print-DT trafficQInsp-DT流量QoS要求QInsp-DT traffic QoS requirementspck_loss_rate_qos:5％pck_loss_rate_qos: 5%pck_loss_rate_qos:20％pck_loss_rate_qos: 20%latency_qos:20mslatency_qos: 20mslatency_qos:100mslatency_qos: 100mspriority:1priority: 1priority:2priority: 2

在表1中，Print-DT的流量QoS要求包括丢包率：5％、最大延时：20ms和优先级：1；QInsp-DT的流量QoS要求包括丢包率：20％、最大延时：100ms和优先级：2。由表1可知，Print-DT对网络质量的要求(丢包率：5％、最大延时：20ms)高于QInsp-DT对网络质量的要求(丢包率：20％、最大延时：100ms)，因此，Print-DT的优先级高于QInsp-DT，并设置Print-DT的优先级等级为1，QInsp-DT的优先级等级为2。In Table 1, the traffic QoS requirements of Print-DT include packet loss rate: 5%, maximum delay: 20ms and priority: 1; the traffic QoS requirements of QInsp-DT include packet loss rate: 20%, maximum delay: 100ms and Priority: 2. It can be seen from Table 1 that Print-DT's requirements for network quality (packet loss rate: 5%, maximum delay: 20ms) are higher than QInsp-DT's requirements for network quality (packet loss rate: 20%, maximum delay: 100ms ), therefore, the priority of Print-DT is higher than that of QInsp-DT, and the priority level of Print-DT is set to 1, and the priority level of QInsp-DT is set to 2.

网络控制器从系统数字孪生集管理模块获取IIoT生产系统的系统数字孪生集中各设备数字孪生体的QoS要求后，可以根据各设备数字孪生体的QoS要求生成各设备数字孪生体的第一流量管理规则。其中，第一流量管理规则至少包括流量管理规则标识、丢包率、最大延时和规则优先级。例如，可以根据如表1所示的各个设备数字孪生体的QoS要求，生成如表2所示的第一流量管理规则：After the network controller obtains the QoS requirements of each equipment digital twin in the system digital twin set management module of the IIoT production system, it can generate the first flow management of each equipment digital twin according to the QoS requirements of each equipment digital twin rule. Wherein, the first flow management rule includes at least a flow management rule identifier, a packet loss rate, a maximum delay, and a rule priority. For example, the first traffic management rule shown in Table 2 can be generated according to the QoS requirements of each device digital twin shown in Table 1:

表2Table 2

Print-DT第一流量管理规则Print-DT first flow management ruleQInsp-DT第一流量管理规则QInsp-DT first traffic management rulepck_loss_rate:5％pck_loss_rate: 5%pck_loss_rate:20％pck_loss_rate: 20%latency:20mslatency: 20mslatency:100mslatency: 100mspriority:1priority: 1priority:2priority: 2

在表2中，与表1对应，Print-DT第一流量管理规则包括丢包率：5％、最大延时：20ms和规则优先级：1；QInsp-DT第一流量管理规则包括丢包率：20％、最大延时：100ms和规则优先级：2。In Table 2, corresponding to Table 1, the first flow management rule of Print-DT includes packet loss rate: 5%, maximum delay: 20ms and rule priority: 1; the first flow management rule of QInsp-DT includes packet loss rate : 20%, maximum delay: 100ms and rule priority: 2.

网络控制器生成各设备数字孪生体的第一流量管理规则后，可以将各设备数字孪生体的第一流量管理规则发送至网络控制代理，设备数字孪生体管理模块可以通过网络控制代理获取第一流量管理规则。当设备数字孪生体执行对应的系统任务后，可以将第一流量管理规则添加至第一数据包中，得到第二数据包。例如，可以将第一流量管理规则中的丢包率、最大延时和规则优先级等数据添加至第一数据包中。对应生成的第二数据包中可以至少包括第一数据包关联的工业物联网系统标识、丢包率、最大延时和第一数据包所属的设备数字孪生体的优先级。After the network controller generates the first traffic management rules of the digital twins of each device, it can send the first traffic management rules of the digital twins of each device to the network control agent, and the device digital twin management module can obtain the first flow management rules through the network control agent. traffic management rules. After the device digital twin executes the corresponding system task, the first traffic management rule can be added to the first data packet to obtain the second data packet. For example, data such as packet loss rate, maximum delay, and rule priority in the first traffic management rule may be added to the first data packet. The correspondingly generated second data packet may at least include the ID of the industrial Internet of Things system associated with the first data packet, the packet loss rate, the maximum delay, and the priority of the digital twin of the device to which the first data packet belongs.

本公开示例实施方式中，第一数据包为SenML数据包，第二数据包为SenML增强数据包。具体地，各个设备数字孪生体通过设备数字孪生体管理模块与系统数字孪生集管理模块进行交互，并根据系统数字孪生集管理模块的指令执行系统任务。例如，Print-DT控制锡膏印刷机对PCB(Printed Circuit Board，印制电路板)板进行锡膏印刷，QInsp-DT控制质检设备检测锡膏印刷质量。各个设备数字孪生体可以将对应的物理设备的SenML数据包反馈至设备数字孪生体管理模块，通过设备数字孪生体管理模块对SenML数据包进行扩展，新增如表3所示的四个元数据：In an exemplary embodiment of the present disclosure, the first data packet is a SenML data packet, and the second data packet is a SenML enhanced data packet. Specifically, each equipment digital twin interacts with the system digital twin set management module through the equipment digital twin set management module, and executes system tasks according to the instructions of the system digital twin set management module. For example, Print-DT controls the solder paste printing machine to print solder paste on PCB (Printed Circuit Board, printed circuit board) board, and QInsp-DT controls the quality inspection equipment to detect the quality of solder paste printing. Each device digital twin can feed back the SenML data package of the corresponding physical device to the device digital twin management module, expand the SenML data package through the device digital twin management module, and add four metadata as shown in Table 3 :

表3table 3

举例而言，对于Print-DT的SenML数据包，可以新增四个元数据依次为sys_name:SMT、latency：20ms、pck_loss_rate：5％和priority:1，分别表示该数据包关联的IIoT生产系统为SMT生产系统、可接受的数据最大延时为20ms、可接受的最大丢包率为5％以及该数据包所属的设备数字孪生体(即Print-DT)在系统数字孪生集(即S-DT-smt)中的优先级等级为1。For example, for the SenML data package of Print-DT, four new metadata can be added in order: sys_name: SMT, latency: 20ms, pck_loss_rate: 5% and priority: 1, respectively indicating that the IIoT production system associated with the data package is SMT production system, the maximum acceptable data delay is 20ms, the maximum acceptable packet loss rate is 5%, and the digital twin of the device to which the data packet belongs (ie Print-DT) is in the system digital twin set (ie S-DT -smt) has a priority level of 1.

扩展后的SenML数据包为SenML增强数据包。例如，Print-DT的一种SenML增强数据包为[{“sys_name”:“SMT”,“latency”：“20,”pck_loss_rate”：“5”,“priority”:“1”，“n”:“urn:dev:10e1033”,“t”:0,“u”:“V”,“v”:120.1}]，表示该增强数据包关联的IIoT生产系统为SMT生产系统，可接受的数据最大延时为20ms，可接受的最大丢包率为5％，该增强数据包所属的设备数字孪生体在系统数字孪生集中的优先级等级为1，对应的物理设备名称为10e1033，时间戳为0，数据单元为V，测量值为120.1。The extended SenML data package is a SenML enhanced data package. For example, a SenML enhanced data package of Print-DT is [{"sys_name":"SMT", "latency": "20,"pck_loss_rate":"5", "priority":"1", "n": "urn:dev:10e1033", "t":0, "u": "V", "v":120.1}], indicating that the IIoT production system associated with the enhanced data package is an SMT production system, and the maximum acceptable data The delay is 20ms, and the maximum acceptable packet loss rate is 5%. The device digital twin to which the enhanced data packet belongs has a priority level of 1 in the system digital twin set, the corresponding physical device name is 10e1033, and the timestamp is 0 , the data unit is V, and the measured value is 120.1.

参考图3所示，示意性的给出了增强SenML数据包流程中的各个结构和各个元素。各个结构依次为物理设备301、设备数字孪生体303、设备数字孪生体管理模块(DT-M)305、网络控制代理(NC-A)306、系统数字孪生体管理模块(S-DT-M)308和网络控制器(NC)309，各个元素依次为原始数据302、SenML数据包304、SenML增强数据包307。Referring to FIG. 3 , each structure and each element in the enhanced SenML data packet process is schematically shown. Each structure is followed byphysical equipment 301, equipmentdigital twin 303, equipment digital twin management module (DT-M) 305, network control agent (NC-A) 306, system digital twin management module (S-DT-M) 308 and a network controller (NC) 309, each element is theoriginal data 302, theSenML data packet 304, and the SenMLenhanced data packet 307 in turn.

具体地，物理设备301将该设备的原始数据302传入对应的设备数字孪生体303中，设备数字孪生体303将原始数据302转化为SenML数据包304，并将SenML数据包304发送至设备数字孪生体管理模块305；设备数字孪生体管理模块305可以利用从网络控制代理306获取的流量管理规则对SenML数据包304进行扩展，生成SenML增强数据包307，并将SenML增强数据包307同步至系统数字孪生体管理模块308；设备数字孪生体管理模块305也可以利用网络控制器309下发的更新后的流量管理规则动态调整SenML增强数据包307。Specifically, thephysical device 301 transfers theoriginal data 302 of the device into the corresponding devicedigital twin 303, and the devicedigital twin 303 converts theoriginal data 302 into aSenML data packet 304, and sends theSenML data packet 304 to the device digital twin. The twinbody management module 305; the device digital twinbody management module 305 can use the traffic management rules obtained from thenetwork control agent 306 to expand theSenML data package 304, generate a SenMLenhanced data package 307, and synchronize the SenML enhanceddata package 307 to the system The digitaltwin management module 308 and the device digitaltwin management module 305 can also dynamically adjust the SenML enhanceddata package 307 by using the updated traffic management rules issued by thenetwork controller 309 .

本公开实施例中，在包含分布式架构的工业物联网系统中，使用增强数据包进行系统通信，并将SenML增强数据包作为统一的通信数据格式。便于后续根据自适应更新后的流量管理规则动态调整增强数据包，可以降低网络质量波动对系统生产效率的影响，从而提升系统的生产效率和可靠性。In the embodiment of the present disclosure, in the industrial Internet of Things system including the distributed architecture, the enhanced data packet is used for system communication, and the SenML enhanced data packet is used as a unified communication data format. It is convenient for subsequent dynamic adjustment of enhanced data packets according to the adaptively updated traffic management rules, which can reduce the impact of network quality fluctuations on system production efficiency, thereby improving system production efficiency and reliability.

在步骤S230中，所述网络控制器根据当前网络质量更新所述第一流量管理规则，得到第二流量管理规则，并将所述第二流量管理规则下发至所述设备数字孪生体管理模块。In step S230, the network controller updates the first traffic management rule according to the current network quality to obtain a second traffic management rule, and sends the second traffic management rule to the device digital twin management module .

一种示例实施方式中，仍以SMT生产系统为例，从系统数字孪生集管理模块获取系统数字孪生集S-DT-smt中各个设备数字孪生体的QoS要求，初始化各个设备数字孪生体的第一流量管理规则。其中，可以根据各个设备数字孪生体的QoS要求，为各个设备数字孪生体的第一流量管理规则进行优先级排序，得到如表4所示的各个设备数字孪生体的第一流量管理规则：In an exemplary embodiment, still taking the SMT production system as an example, the QoS requirements of each device digital twin in the system digital twin set S-DT-smt are obtained from the system digital twin set management module, and the first-order QoS requirements of each device digital twin are initialized. A traffic management rule. Among them, according to the QoS requirements of each device digital twin, the first traffic management rules of each device digital twin can be prioritized, and the first traffic management rules of each device digital twin are obtained as shown in Table 4:

表4Table 4

在表4中，Print-DT第一流量管理规则的优先级高于QInsp-DT第一流量管理规则的优先级，QInsp-DT第一流量管理的优先级高于Cam-DT第一流量管理规则的优先级。Print-DT第一流量管理规则包括丢包率：5％、最大延时：20ms和优先级：1，QInsp-DT第一流量管理规则包括丢包率：20％、最大延时：100ms和优先级：2，Cam-DT第一流量管理规则包括丢包率：100％、最大延时：200ms和优先级：3。In Table 4, the priority of the first traffic management rule of Print-DT is higher than that of the first traffic management rule of QInsp-DT, and the priority of the first traffic management rule of QInsp-DT is higher than that of the first traffic management rule of Cam-DT priority. Print-DT first flow management rules include packet loss rate: 5%, maximum delay: 20ms and priority: 1, QInsp-DT first flow management rules include packet loss rate: 20%, maximum delay: 100ms and priority Level: 2, Cam-DT's first traffic management rules include packet loss rate: 100%, maximum delay: 200ms and priority: 3.

网络控制器通过与各个网络控制代理通信，获取各个边缘节点的网络数据，以实现对各个边缘节点网络环境的实时检测。当检测到当前网络质量较高如当前网络处于无拥塞状态时，网络控制器不需要激活流量管理规则，按照best-effort方式通信即可。其中，best-effort方式是指当网络发生拥塞时，立即丢弃数据包，直到业务量有所减少为止。The network controller obtains the network data of each edge node by communicating with each network control agent, so as to realize the real-time detection of the network environment of each edge node. When it is detected that the current network quality is relatively high, for example, the current network is in a non-congested state, the network controller does not need to activate traffic management rules, and can communicate in a best-effort manner. Among them, the best-effort mode means that when the network is congested, data packets are discarded immediately until the traffic volume decreases.

一种示例实施方式中，当检测到当前网络处于轻微拥塞状态时，也就是当前网络的目标服务质量参数小于系统数字孪生集中各设备数字孪生体的目标服务质量参数时，网络控制器将第一流量管理规则中设备数字孪生体的目标服务质量参数赋值为当前网络的目标服务质量参数。其中，目标服务质量参数是指丢包率、最大延时等参数。In an example implementation, when it is detected that the current network is in a slightly congested state, that is, when the target quality of service parameter of the current network is smaller than the target quality of service parameter of each device digital twin in the system digital twin set, the network controller will first The target quality of service parameters of the device digital twin in the traffic management rules are assigned as the target quality of service parameters of the current network. Wherein, the target QoS parameters refer to parameters such as packet loss rate and maximum delay.

举例而言，各设备数字孪生体的QoS要求如表4所示，若当前网络的丢包率为3％，最大延时为15ms，可以看出，当前网络的丢包率和最大延时均小于各设备数字孪生体的QoS要求。此时，可以将各设备数字孪生体的第一流量管理规则进行如公式(1)所示的调整：For example, the QoS requirements of the digital twins of each device are shown in Table 4. If the packet loss rate of the current network is 3% and the maximum delay is 15ms, it can be seen that the packet loss rate and maximum delay of the current network are both Less than the QoS requirements of each device's digital twin. At this point, the first traffic management rules of the digital twins of each device can be adjusted as shown in formula (1):

公式(1)表示，将各设备数字孪生体的第一流量管理规则中的丢包率和最大延时赋值为当前网络的丢包率和最大延时，可以得到如表5所示的各个设备数字孪生体的第二流量管理规则：Formula (1) shows that assigning the packet loss rate and maximum delay in the first traffic management rule of each device's digital twin to the packet loss rate and maximum delay of the current network, each device as shown in Table 5 can be obtained Second Traffic Management Rules for Digital Twins:

表5table 5

在表5中，Print-DT、QInsp-DT和Cam-DT三个设备数字孪生体对应的第二流量管理规则中的丢包率和最大延时均调整为：丢包率：3％、最大延时：15ms。In Table 5, the packet loss rate and maximum delay in the second traffic management rules corresponding to the three device digital twins of Print-DT, QInsp-DT and Cam-DT are adjusted to: packet loss rate: 3%, maximum Delay: 15ms.

该示例中，网络控制模块周期性地检测网络质量，并动态更新流量管理原则，通过实时检测网络质量可以灵活地进行流量管理，从而保证工业物联网系统的生产效率。In this example, the network control module periodically detects the network quality and dynamically updates the flow management principles. By detecting the network quality in real time, the flow management can be performed flexibly, thereby ensuring the production efficiency of the industrial Internet of Things system.

另一种示例实施方式中，当检测到当前网络处于严重拥塞状态时，参考图4所示，可以根据步骤S401至步骤S403实现对流量管理规则的调整：In another exemplary embodiment, when it is detected that the current network is in a state of severe congestion, as shown in FIG. 4 , adjustments to traffic management rules may be implemented according to steps S401 to S403:

在步骤S401中，当所述当前网络的目标服务质量参数大于所述系统数字孪生集中任一所述设备数字孪生体的目标服务质量参数时，确定所述设备数字孪生体的优先级所属的优先级区间。In step S401, when the target quality of service parameter of the current network is greater than the target quality of service parameter of any of the device digital twins in the system digital twin set, determine the priority to which the priority of the device digital twin belongs grade interval.

其中，目标服务质量参数是指丢包率、最大延时等参数。若当前网络的丢包率和最大延时大于系统数字孪生集中任一设备数字孪生体的丢包率和最大延时，可以确定各个设备数字孪生体的优先级所属的优先级区间。Wherein, the target QoS parameters refer to parameters such as packet loss rate and maximum delay. If the packet loss rate and maximum delay of the current network are greater than the packet loss rate and maximum delay of any device digital twin in the system digital twin set, the priority interval to which the priority of each device digital twin belongs can be determined.

具体地，若系统数字孪生集中包含的设备数字孪生体的数量为M，可以根据各个设备数字孪生体的优先级将系统数字孪生集中所有的设备数字孪生体进行排序，如根据优先级从高到低进行排列为{DT₁，DT₂，…，DT_M}，其中，丢包率和最大延时超过QoS要求的设备数字孪生体的数量为N，则可以将优先级分为三个区间，分别为第一优先级区间(i≤N)、第二优先级区间(N<i≤M-N)和第三优先级区间(M-N<i≤M)。然后可以根据各个设备数字孪生体的优先级确定所属的优先级区间。Specifically, if the number of equipment digital twins contained in the system digital twin set is M, all equipment digital twins in the system digital twin set can be sorted according to the priority of each equipment digital twin, for example, according to the priority from high to Arranged as {DT₁ , DT₂ ,...,DT_M }, where the number of digital twins of devices whose packet loss rate and maximum delay exceed the QoS requirements is N, then the priority can be divided into three intervals, They are the first priority interval (i≤N), the second priority interval (N<i≤MN) and the third priority interval (MN<i≤M). Then the priority interval to which it belongs can be determined according to the priority of each equipment digital twin.

举例而言，各设备数字孪生体的QoS要求如表4所示，将Print-DT、QInsp-DT和Cam-DT按照优先级从高到低排序依次为Print-DT(DT₁)、QInsp-DT(DT₂)和Cam-DT(DT₃)，i的取值为1、2和3，用于表征优先级。若当前网络的丢包率为15％，最大延时为80ms，可以看出，当前网络的丢包率和最大延时大于Print-DT的QoS要求(丢包率为5％，最大延时为20ms)，当前网络的丢包率和最大延时小于QInsp-DT的QoS要求(丢包率为20％，最大延时为100ms)和Cam-DT的QoS要求(丢包率为100％，最大延时为200ms)。因此，可以确定当前网络的丢包率和最大延时超过QoS要求的设备数字孪生体的数量N＝1，对应的，第一优先级区间为i≤1，第二优先级区间1<i≤2，第三优先级区间为2<i≤3。可以看出，Print-DT的优先级位于第一优先级区间，QInsp-DT位于第二优先级区间，Cam-DT位于第三优先级区间。For example, the QoS requirements of the digital twins of each device are shown in Table 4. Print-DT, QInsp-DT and Cam-DT are sorted from high to low in order of priority as Print-DT(DT₁ ), QInsp- In DT (DT₂ ) and Cam-DT (DT₃ ), the values of i are 1, 2 and 3, which are used to represent the priority. If the packet loss rate of the current network is 15%, and the maximum delay is 80ms, it can be seen that the packet loss rate and the maximum delay of the current network are greater than the QoS requirements of Print-DT (the packet loss rate is 5%, and the maximum delay is 20ms), the packet loss rate and the maximum delay of the current network are less than the QoS requirements of QInsp-DT (the packet loss rate is 20%, the maximum delay is 100ms) and the QoS requirements of Cam-DT (the packet loss rate is 100%, the maximum The delay is 200ms). Therefore, it can be determined that the packet loss rate and maximum delay of the current network exceed the number of device digital twins N=1 required by QoS. Correspondingly, the first priority interval is i≤1, and the second priority interval is 1<i≤ 2. The third priority range is 2<i≤3. It can be seen that the priority of Print-DT is in the first priority interval, the QInsp-DT is in the second priority interval, and the Cam-DT is in the third priority interval.

在步骤S402中，当所述设备数字孪生体的优先级位于第一优先级区间或第三优先级区间时，所述网络控制器将所述第一流量管理规则中所述设备数字孪生体的目标服务质量参数赋值为所述系统数字孪生集中所述设备数字孪生体的目标服务质量参数。In step S402, when the priority of the digital twin of the device is in the first priority range or the third priority range, the network controller sets the digital twin of the device in the first traffic management rule to The target quality of service parameter is assigned as the target quality of service parameter of the equipment digital twin in the system digital twin set.

确定设备数字孪生体的优先级位于第一优先级区间或者第三优先级区间时，可以将各设备数字孪生体的第一流量管理规则进行如公式(2)所示的调整：When it is determined that the priority of the digital twin of the equipment is in the first priority interval or the third priority interval, the first flow management rules of the digital twin of each equipment can be adjusted as shown in formula (2):

公式(2)表示，将对应的设备数字孪生体的第一流量管理规则中的丢包率和最大延时赋值为系统数字孪生集中各设备数字孪生体的QoS要求中的丢包率和最大延时。Formula (2) indicates that the packet loss rate and maximum delay in the first traffic management rule of the corresponding device digital twin are assigned as the packet loss rate and maximum delay in the QoS requirements of each device digital twin in the system digital twin set Time.

例如，确定Print-DT的优先级位于第一优先级区间，Cam-DT的优先级位于第三优先级区间时，可以将表5中Print-DT第一流量管理规则中的丢包率调整为5％，最大延时调整为20ms，将Cam-DT第一流量管理规则中的丢包率调整为100％，最大延时调整为200ms。For example, when it is determined that the priority of Print-DT is in the first priority interval and the priority of Cam-DT is in the third priority interval, the packet loss rate in the first traffic management rule of Print-DT in Table 5 can be adjusted to 5%, the maximum delay is adjusted to 20ms, the packet loss rate in the Cam-DT first flow management rule is adjusted to 100%, and the maximum delay is adjusted to 200ms.

在步骤S403中，当所述设备数字孪生体的优先级位于第二优先级区间时，所述网络控制器将所述第一流量管理规则中所述设备数字孪生体的目标服务质量参数赋值为所述当前网络的目标服务质量参数。In step S403, when the priority of the digital twin of the device is in the second priority interval, the network controller assigns the target quality of service parameter of the digital twin of the device in the first traffic management rule to be The target QoS parameter of the current network.

确定设备数字孪生体的优先级位于第二优先级区间时，可以将对应设备数字孪生体的第一流量管理规则进行如公式(3)所示的调整：When it is determined that the priority of the equipment digital twin is in the second priority interval, the first traffic management rule of the corresponding equipment digital twin can be adjusted as shown in formula (3):

公式(3)表示，将对应设备数字孪生体的第一流量管理规则中的丢包率和最大延时赋值为当前网络的丢包率和最大延时。Formula (3) indicates that the packet loss rate and maximum delay in the first traffic management rule of the corresponding device digital twin are assigned as the packet loss rate and maximum delay of the current network.

例如，确定QInsp-DT的优先级位于第二优先级区间时，可以将表5中QInsp-DT第一流量管理规则中的丢包率调整为15％，最大延时调整为80ms。For example, when it is determined that the priority of QInsp-DT is in the second priority interval, the packet loss rate in the first traffic management rule of QInsp-DT in Table 5 can be adjusted to 15%, and the maximum delay can be adjusted to 80ms.

综上，根据公式(2)和公式(3)调整第一流量管理规则后，可以得到如表6所示的各个设备数字孪生体的第二流量管理规则：In summary, after adjusting the first traffic management rules according to formula (2) and formula (3), the second traffic management rules of each device digital twin can be obtained as shown in Table 6:

表6Table 6

该示例中，网络控制模块周期性地检测网络质量，并动态更新流量管理原则，通过实时检测网络质量可以灵活地进行流量管理，从而保证工业物联网系统的生产效率。In this example, the network control module periodically detects the network quality and dynamically updates the flow management principles. By detecting the network quality in real time, the flow management can be performed flexibly, thereby ensuring the production efficiency of the industrial Internet of Things system.

在步骤S240中，所述设备数字孪生体管理模块根据所述第二流量管理规则调整所述第二数据包中的扩展数据。In step S240, the device digital twin management module adjusts the extended data in the second data packet according to the second traffic management rule.

网络控制器生成各个设备数字孪生体的第二流量管理规则后，可以将第二流量管理规则发送至网络控制代理，设备数字孪生体管理模块再从网络控制代理获取第二流量管理规则，并根据第二流量管理规则调整第二数据包中的扩展数据。After the network controller generates the second traffic management rules of each device digital twin, it can send the second traffic management rules to the network control agent, and the device digital twin management module obtains the second traffic management rules from the network control agent, and according to The second traffic management rule adjusts the extension data in the second data packet.

举例而言，对于Print-DT生成的SenML增强数据包，其中的扩展数据为[{“sys_name”:“SMT”,“latency”：“20,”pck_loss_rate”：“5”,“priority”:“1”}]。若Print-DT的第二流量管理规则中的丢包率为3％，最大延时为15ms，优先级不变，则可以将该增强数据包中的丢包率和最大延时进行调整，调整后的扩展数据为[{“sys_name”:“SMT”,“latency”：“15,”pck_loss_rate”：“3”,“priority”:“1”}]。For example, for the SenML enhanced data package generated by Print-DT, the extended data is [{"sys_name":"SMT", "latency": "20,"pck_loss_rate":"5", "priority":" 1”}]. If the packet loss rate in the second flow management rule of Print-DT is 3%, the maximum delay is 15ms, and the priority remains unchanged, then the packet loss rate and maximum delay in the enhanced data packet can be The adjusted extended data is [{"sys_name":"SMT","latency":"15,"pck_loss_rate":"3","priority":"1"}].

该示例中，根据自适应更新后的流量管理规则动态调整增强数据包，可以降低网络质量波动对系统生产效率的影响，从而提升系统的生产效率和可靠性。In this example, the dynamic adjustment of enhanced data packets according to the adaptively updated traffic management rules can reduce the impact of network quality fluctuations on system production efficiency, thereby improving system production efficiency and reliability.

一种示例实施方式中，当设备数字孪生体执行对应的系统任务出现异常时，系统数字孪生体管理模块可以根据接收到的异常数据更新系统数字孪生集，并通过网络控制器更新第一流量管理规则或第二流量管理规则。例如，当QInsp-DT检测出锡膏印刷质量存在异常时，可以将异常数据上报至系统数字孪生体管理模块，系统数字孪生体管理模块根据接收到的异常数据更新对应的系统数字孪生集，即S-DT-smt。同时，通知网络控制器更新当前的流量管理规则，并下达指令至各设备数字孪生体，以根据更新后的流量管理规则执行对应的系统任务。In an exemplary embodiment, when the corresponding system task of the equipment digital twin is abnormal, the system digital twin management module can update the system digital twin set according to the received abnormal data, and update the first traffic management through the network controller rules or secondary traffic management rules. For example, when QInsp-DT detects that the printing quality of solder paste is abnormal, it can report the abnormal data to the system digital twin management module, and the system digital twin management module updates the corresponding system digital twin set according to the received abnormal data, namely S-DT-smt. At the same time, notify the network controller to update the current traffic management rules, and issue instructions to the digital twins of each device to perform corresponding system tasks according to the updated traffic management rules.

示例性的，系统数字孪生体管理模块可以根据与异常数据对应的目标设备数字孪生体更新系统数字孪生集，并通过网络控制器根据目标设备数字孪生体的服务质量参数更新第一流量管理规则或第二流量管理规则。例如，系统数字孪生体管理模块可以将与异常数据对应的目标设备数字孪生体添加至系统数字孪生集中，并通过网络控制器将目标设备数字孪生体的服务质量参数添加至第一流量管理规则或第二流量管理规则中。再例如，系统数字孪生体管理模块可以系统数字孪生集中删除与异常数据对应的目标设备数字孪生体，并通过网络控制器将目标设备数字孪生体的服务质量参数从第一流量管理规则或第二流量管理规则中删除。Exemplarily, the system digital twin management module may update the system digital twin set according to the target device digital twin corresponding to the abnormal data, and update the first traffic management rule or A second traffic management rule. For example, the system digital twin management module can add the target device digital twin corresponding to the abnormal data to the system digital twin set, and add the service quality parameters of the target device digital twin to the first traffic management rule or In the second traffic management rule. For another example, the system digital twin management module can centrally delete the target device digital twin corresponding to abnormal data from the system digital twin, and change the service quality parameters of the target device digital twin from the first traffic management rule or the second traffic management rule through the network controller. Deleted in traffic management rules.

举例而言，当QInsp-DT检测出锡膏印刷质量存在异常时，对应的目标设备数字孪生体为Cam-DT。系统数字孪生体管理模块可以将Cam-DT新增至S-DT-smt，同时，网络控制器可以根据Cam-DT的QoS要求生成对应的流量管理规则，并将该流量管理规则添加至当前的流量管理规则中。例如，当前的流量管理规则如表2所示，更新后的流量管理规则如表4所示。根据实际需求，当前的流量管理规则可以是第一流量管理规则或第二流量管理规则，本公开对此不做限定。然后，对Cam-DT下达指令，以使Cam-DT根据Cam-DT的流量管理规则操控辅助质检IP相机拍摄质量异常的PCB板，反馈拍摄数据至系统数字孪生体管理模块用于辅助质量检测，直至异常事件解除。For example, when QInsp-DT detects that the printing quality of solder paste is abnormal, the corresponding digital twin of the target device is Cam-DT. The system digital twin management module can add Cam-DT to S-DT-smt. At the same time, the network controller can generate corresponding traffic management rules according to the QoS requirements of Cam-DT, and add the traffic management rules to the current in traffic management rules. For example, the current traffic management rules are shown in Table 2, and the updated traffic management rules are shown in Table 4. According to actual requirements, the current traffic management rule may be the first traffic management rule or the second traffic management rule, which is not limited in the present disclosure. Then, give an instruction to Cam-DT, so that Cam-DT controls the auxiliary quality inspection IP camera to capture abnormal quality PCB boards according to the traffic management rules of Cam-DT, and feeds back the shooting data to the digital twin management module of the system for auxiliary quality inspection , until the abnormal event is resolved.

消除系统任务出现的异常后，系统数字孪生体管理模块可以再次根据与异常数据对应的目标设备数字孪生体更新系统数字孪生集，并通过网络控制器根据目标设备数字孪生体的服务质量参数更新第一流量管理规则或第二流量管理规则。例如，从系统数字孪生集中删除/添加目标设备数字孪生体，并通过网络控制器从第一流量管理规则或第二流量管理规则中删除/添加目标设备数字孪生体的服务质量参数。举例而言，当QInsp-DT检测锡膏印刷质量合格时，系统数字孪生体管理模块从表4中删除Cam-DT的流量管理规则，并下达指令至各设备数字孪生体，以根据最新的流量管理规则执行对应的系统任务。After eliminating the abnormality of the system task, the system digital twin management module can update the system digital twin set again according to the target device digital twin corresponding to the abnormal data, and update the second set of digital twins according to the service quality parameters of the target device digital twin through the network controller. A traffic management rule or a second traffic management rule. For example, delete/add the target device digital twin from the system digital twin set, and delete/add the service quality parameter of the target device digital twin from the first traffic management rule or the second traffic management rule through the network controller. For example, when QInsp-DT detects that the printing quality of solder paste is qualified, the system digital twin management module deletes the traffic management rules of Cam-DT from Table 4, and issues instructions to the digital twins of each device, so that according to the latest flow Management rules execute corresponding system tasks.

本公开示例实施方式中，基于自适应流量管理规则，并根据IIoT生产系统的实际需求，动态更新系统数字孪生集，从而实现对生产系统内各物理设备的灵活调度和编排，最终实现对生产系统的动态重构，助力工业柔性制造的智能发展。In the exemplary embodiment of the present disclosure, based on adaptive traffic management rules and according to the actual needs of the IIoT production system, the digital twin set of the system is dynamically updated, so as to realize the flexible scheduling and arrangement of each physical device in the production system, and finally realize the control of the production system.

After the communication connection is established, each DT converts the raw data from the corresponding physical device into a SenML data packet;

DT executes system production tasks: each DT interacts with S-DT-M through DT-M, and executes corresponding system tasks according to the instructions of S-DT-M. Specifically, Print-DT controls the solder paste printing machine to print solder paste on the PCB, QInsp-DT controls the inspection equipment to detect the quality of solder paste printing, and generates corresponding SenML enhanced data packets through DT-M for their respective SenML data packets. Synchronize the generated SenML enhanced data package to S-DT-M;

DT-M manages the life cycle of each DT: the network control module periodically detects the network quality, dynamically updates the traffic management principle according to the real-time network quality, and publishes it to the DT-M for execution. The management principle modifies the extended data in the SenML enhanced data package of each DT;

当检测到当前网络处于轻微拥塞状态时，如当前网络的丢包率为4％，最大延时为10ms，可以更新表2中各DT的流量管理规则，更新后的流量管理规则如表7所示：When it is detected that the current network is in a state of slight congestion, such as the packet loss rate of the current network is 4%, and the maximum delay is 10ms, the traffic management rules of each DT in Table 2 can be updated. The updated traffic management rules are shown in Table 7 Show:

另外，当DT执行生产任务出现异常时，如当QInsp-DT检测出锡膏印刷质量存在异常时，系统数字孪生体管理模块可以将Cam-DT新增至S-DT-smt，以利用Cam-DT辅助质量检测。同时，S-DT-M通知网络控制器更新如表7所示的流量管理规则，得到如表8所示的流量管理规则，并下达指令至各DT执行对应的流量管理规则，直至异常事件解除；In addition, when DT executes production tasks abnormally, such as when QInsp-DT detects abnormalities in solder paste printing quality, the system digital twin management module can add Cam-DT to S-DT-smt to utilize Cam-DT DT assisted quality inspection. At the same time, S-DT-M notifies the network controller to update the traffic management rules shown in Table 7, obtains the traffic management rules shown in Table 8, and issues instructions to each DT to execute the corresponding traffic management rules until the abnormal event is resolved ;
