Description

Intelligent production line monitoring method and system based on industrial large model

Technical Field

The application relates to the technical field of artificial intelligence, in particular to an intelligent production line monitoring method and system based on an industrial large model.

Background

Currently, the network services provided by the fifth generation mobile communication technology (5th Generation Mobile Communication Technology,5G) have been deeply converged into the industry. Taking an intelligent production line as an example, different production lines can communicate through a 5G side uplink so as to realize interaction of production behaviors. For example, because the production efficiency of different production lines is different, the order congestion degree on different production lines is also not used, so that the order can be flexibly allocated between different production lines through side-link communication, and the problem that the order congestion is caused by too centralizing the order in certain production lines to influence the production efficiency is avoided.

However, due to the limited amount of resources of the sidestream resources, a large amount of sidestream communications may cause communication congestion, affect the quality of communication between different production lines, and may cause a decrease in order production efficiency.

The technical solutions in the present application will be described below with reference to the accompanying drawings.

Referring to fig. 2, an embodiment of the present application provides a communication system, including: network equipment and terminals.

The network device may be an AF in the above 5GS, i.e. an application function network element. The application function network element serves a certain service, and the specific type of the service is not limited.

The terminal may be a control terminal or a communication terminal of the production line. The communication between the application function network element and the production line is understood to be a communication between the application function network element and a control terminal or a communication terminal of the production line.

In the communication system, when the production state change condition of each of a plurality of production lines in a specified time period is obtained, the application function network element can process the production state change condition of each of the plurality of production lines in the specified time period through an industrial large model so as to estimate the situation that side communication congestion of some production lines possibly occurs in the future. For example, information that the second line sends to the first line over the sidelink in the future may cause the first line to experience sidelink congestion. If the first production line is congested, that is, the second production line finds that packet loss occurs in the second production line, the second production line starts multiple packet transmission of the side link under the condition that packet loss occurs in the side link, so that the first production line is congested. Therefore, the application function network element can reduce the packet loss redundancy tolerance of the second production line in advance, so that the second production line is prevented from starting the side uplink multiple packet transmission after the second production line, thereby the side communication is congested, and the order production efficiency is ensured.

The interaction between the network device and the control terminal in the above communication system will be described in detail with reference to the method.

Referring to fig. 3, an embodiment of the present application provides an intelligent production line monitoring method based on an industrial large model, which includes:

s301, the application function network element monitors a plurality of production lines to obtain the production state change condition of each production line in a specified time period.

The plurality of production lines are each for executing a production action for an order of a business, the plurality of production lines being capable of communicating with each other via a side-link.

The application function network element can send monitoring indication information to a plurality of production lines through an operator network. Wherein the plurality of production lines access and register with an operator network, which may be a public land mobile network (Public Land Mobile Network, PLMN). The application function network element is an application function network element of a third party outside the operator network. The monitoring indication information is used for indicating that the monitoring indication information needs to monitor the production state change condition of the production line per se within a specified time period, for example, the monitoring indication information can comprise information for indicating the specified time period and an indication cell, and the indication cell is used for indicating the production state change condition of the production line per se needs to be monitored. The application function network element may send monitoring indication information, such as an AF requirement request message carrying the monitoring indication information, to a NEF network element in the operator network. The NEF network element can authenticate the corresponding functional network element, and under the condition that authentication passes, the NEF network element, the SMF network element, the AMF network element and the RAN equipment sequentially pass through, and monitoring indication information is sent to a plurality of production lines connected to the RAN equipment. Or the NEF network element can directly transmit the monitoring indication information to a plurality of production lines connected to the RAN equipment through the PCF network element, the SMF network element, the AMF network element and the RAN equipment in sequence without authenticating the application function network element.

The production state change conditions of the production lines in the appointed time period can be obtained according to the monitoring indication information. For example, the production state change condition of each of the plurality of production lines within the specified time period may include at least one of: the number of orders for the business that each of the plurality of production lines has completed within the specified time period, the number of orders for the business that each of the plurality of production lines is producing within the specified time period, or the number of orders for the business that each of the plurality of production lines waits to produce within the specified time period.

Wherein the change in the number of orders for the business being produced by each of the plurality of production lines over the specified time period refers to: at the beginning of the specified time period, the number of orders for the business being produced by each of the plurality of production lines differs from the number of orders for the business being produced by each of the plurality of production lines at the end of the specified time period, e.g., the difference between production line 1 and production line 2 is 20, indicating an increase in orders being produced, and the difference between production line 2 is-15, indicating a decrease in orders being produced. Wherein, the change of the order number of the business waiting to be produced in the appointed time period by each of the plurality of production lines means: at the beginning of the specified time period, the number of orders for the service that each of the plurality of production lines waits for production, and at the end of the specified time period, the number of orders for the service that each of the plurality of production lines waits for production, e.g., the difference between production line 1 and production line 2 is-10, indicating that the number of orders waiting for production decreases, and the difference between production line 2 is 10, indicating that the number of orders waiting for production increases. The specified time period may be a time period that starts with a plurality of pieces of production receiving the monitoring indication information and ends after a preset time period passes, and the specific time period may be set according to actual situations, for example, 5 minutes, 10 minutes, and the like, and is not limited.

The multiple production lines can send the production state change conditions of the multiple production lines returned by the multiple production lines according to the monitoring indication information within a specified time period to the application function network element through an operator network (such as an existing signaling transferred between RAN equipment, an AMF network element, an SMF network element, a PCF network element and a NEF network element which are accessed through the multiple production lines in sequence). Correspondingly, the application function network element can receive the production state change condition of each of the production lines returned by the production lines according to the monitoring indication information in a specified time period through the operator network.

S302, the application function network element processes the production state change condition of each of a plurality of production lines in a specified time period through an industrial large model, and determines that the situation of sidestream communication congestion will occur in a first production line.

Wherein the plurality of production lines includes a first production line and a second production line. The industrial large model may be a deep neural network, and the specific network structure may be implemented by referring to the design of the existing deep neural network, which is not described herein. The industrial large model can output result information by processing the production state change condition of each of the plurality of production lines in a specified time period (specifically, the production state change condition of each of the plurality of production lines in the specified time period corresponding to the identifier), wherein the result information can comprise the identifier of the first production line and the respective identifiers of at least two production lines except the first production line in the plurality of production lines, so as to indicate that the situation of lateral communication congestion of the first production line is about to occur.

Specifically, the situation that the first production line is about to have lateral communication congestion may refer to: when the first production line meets the first condition and at least two production lines except the first production line meet the second condition, the at least two production lines can distribute orders of the business waiting for production of the at least two production lines to the first production line through a side link between the at least two production lines and the first production line, so that the first production line is congested in side communication.

Wherein the at least two production lines comprise a second production line. The first production line meeting the first condition may mean that: the number of orders of the business being produced by the first production line at a first moment is smaller than a first order number threshold value, and/or the number of orders of the business waiting to be produced by the first production line at the first moment is smaller than a second order number threshold value, wherein the first moment is the moment predicted at the industrial large model; the at least two production lines meeting the second condition means that: the number of orders of the business being produced by each of the at least two production lines at the first time is greater than a third order number threshold and/or the number of orders of the business waiting to be produced by each of the at least two businesses at the first time is less than a fourth order number threshold. Wherein the third order number threshold is greater than the first order number threshold, the fourth order number threshold is greater than the second order number threshold, and the first order number threshold, the second order number threshold, the third order number threshold, and the fourth order number threshold are thresholds where sidestream traffic congestion occurs. That is, the relationship between the number of orders in the first production line and the first order number threshold and/or the second order number threshold is satisfied, and the relationship between the number of orders in the at least two production lines and the third order number threshold and/or the fourth order number threshold is satisfied, so that the first production line is likely to suffer from side communication congestion.

Wherein the at least two production lines will distribute orders of the business waiting for production of each of the at least two production lines to the first production line through a side link with the first production line may refer to: the at least two production lines send information of orders of the businesses waiting for production when the at least two production lines are at the first moment to the first production line through side links between the at least two production lines and the first production line respectively, so that the first production line can use the orders of the businesses waiting for production when the at least two production lines are at the first moment as the orders of the businesses waiting for production when the first production line is self at the first moment; and after the at least two production lines send the information of the orders of the services waiting to be produced by the at least two production lines respectively at the first moment to the first production line at the first moment, the at least two production lines release the orders of the services waiting to be produced by the at least two production lines respectively at the first moment. For example, the production line 1 will send information about 10 orders of the business waiting for production to the production line 2 via the side links of the production line 1 and the production line 2, the production line 2 may take the 10 orders as its own orders, and at the same time, the production line 2 will release the information about the 10 orders, i.e. the production line 1 will not reproduce the 10 orders anymore, and the 10 orders are handed to the production line 2 for production. The production line 3 will send the information of the 20 orders of the business waiting for production to the production line 2 via the side links of the production line 1 and the production line 2, the production line 2 can take the 30 orders as the own orders, and at the same time, the production line 3 will release the information of the 20 orders, i.e. the production line 3 will not reproduce the 20 orders anymore, and the 20 orders are given to the production line 2 for production.

Alternatively, the industrial large model may also output the number of orders for the business waiting for production that each of the at least two production lines is assigned to the first production line at the first time. For example, the number of orders for the business to be produced in the production line 1 is 10, and the number of orders for the business to be produced in the production line 3 is 20.

S303, the application function network element reduces the packet loss redundancy tolerance of the second production line.

The second production line is a production line which is in lateral communication with the first production line in the plurality of production lines, and if the packet loss redundancy tolerance of the second production line is lower, the probability that the second production line starts the transmission of the lateral uplink multiple packet transmission under the condition that the lateral uplink packet loss occurs is lower.

The second production line can determine whether to start multiple packet transmission for a side uplink between the second production line and the first production line under the condition that the side uplink packet loss occurs in communication between the second production line and the first production line according to the packet loss redundancy tolerance. Wherein, the communication of second production line and first production line appears sideways and loses the packet and means: the data packets sent by the second line to the first line via the side-link between the second line and the first line are not successfully received by the first line. Turning on multiple packet transmissions for the side-links between the second and first lines refers to: the second production line directly repeatedly transmits the same data packet for a plurality of times without considering packet loss, for example, repeatedly transmits one data packet for 2 times to 3 times. The data packets sent by the second line to the first line via the side links between the second line and the first line carry information of the order of the service waiting for production, which the second line distributes to the first line at the first moment.

And the application function network element reduces the packet loss redundancy tolerance of the second production line according to the number of orders of the service waiting to be produced, which is distributed to the first production line at the first moment by the second production line. For example, the application function network element may send the indication information to the second production line in a manner similar to S301, so as to instruct the second production line to reduce the packet loss redundancy tolerance of the second production line through the indication information.

The degree to which the packet loss redundancy tolerance of the second production line is reduced is positively correlated with the number of orders of the service waiting to be produced, which the second production line distributes to the first production line at the first moment. For example, the packet loss redundancy tolerance includes a plurality of levels, and the packet loss redundancy tolerance of different levels corresponds to different order data intervals, and the packet loss redundancy tolerance of different levels also corresponds to intervals of different packet loss rates. The application function network element determines the level of packet loss redundancy tolerance corresponding to the order data interval according to the order number of the service waiting to be produced of the first production line when the second production line is in the first time, so as to determine the interval of packet loss rate corresponding to the level, if the level of packet loss redundancy tolerance is higher, the interval of packet loss rate corresponding to the interval is more loose, if the level of packet loss redundancy tolerance is 1, the interval of packet loss rate is 2-4%, the multiple packet transmission of the side link is started when the packet loss rate of the side link reaches 2-4%, and if the level of packet loss redundancy tolerance is 2, the multiple packet transmission of the side link is started when the packet loss rate of the side link reaches 4-6%, and if the level of packet loss redundancy tolerance is 3, the interval of packet loss rate is 6-8%, the multiple packet transmission of the side link is started when the packet loss rate of the side link reaches 6-8%, and the multiple packet transmission is not repeated.

It is understood that S301-S303 may be periodically performed in a loop.

Optionally, the first production line performs sidestream communication with other production lines except the first production line in the multiple production lines through a sidestream resource pool of the first production line, where the sidestream resource pool of the first production line includes sidestream dedicated resources and sidestream shared resources allocated by an operator network for the first production line, the sidestream dedicated resources are sidestream resources allocated by the operator network for the first production line, and the sidestream shared resources are sidestream resources allocated by the operator network for the first production line and can be shared with other production lines. At this time, in combination with the above S301-S303, the application function network element may also send the sidestream resource requirement information to the access network device (the above RAN device) accessed by the first production line through the operator network. The side line resource demand information is used for indicating that the first production line needs to increase side line special resources; or, the sidestream resource requirement information is used for indicating that the first production line needs to increase sidestream special resources and reduce sidestream shared resources. The application function network element may send the sidestream resource requirement information to the access network device in a manner similar to S301, so that the situation of sidestream resource shortage of the first production line may be relieved.

In summary, when the production state change condition of each of the plurality of production lines in the specified time period is obtained, the application function network element can process the production state change condition of each of the plurality of production lines in the specified time period through the industrial large model so as to estimate the situation that the lateral communication congestion of some production lines may occur in the future. For example, information that the second line sends to the first line over the sidelink in the future may cause the first line to experience sidelink congestion. If the first production line is congested, that is, the second production line finds that packet loss occurs in the second production line, the second production line starts multiple packet transmission of the side link under the condition that packet loss occurs in the side link, so that the first production line is congested. Therefore, the application function network element can reduce the packet loss redundancy tolerance of the second production line in advance, so that the second production line is prevented from starting the side uplink multiple packet transmission after the second production line, thereby the side communication is congested, and the order production efficiency is ensured.
