[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0030] In order to facilitate a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and order of execution.

[0031] With the rapid development of modern information technology, simulation technology has also developed rapidly and has been widely used in the industrial field. In other words, with the rapid development of simulation technology, industrial systems in the industrial field can be simulated (hereinafter referred to as industrial system simulation).

[0032] Industrial system simulation refers to building a mathematical model of the industrial system, using computers or other special equipment to simulate the real industrial environment, converting the modules of the actual system into twin models, simulating the operation process of the actual industrial system, and realizing the simulation and interaction of the workflow. Generally speaking, the general process of industrial system simulation can include system definition and modeling, simulation environment construction, simulation experiment operation, data collection and analysis, and result output and tuning. In other words, the industrial system can be simulated through the general process described above to obtain a twin industrial system.

[0033] Industrial system simulation has a wide range of uses. It not only covers key links such as production line layout optimization and production efficiency improvement, but also plans, simulates and verifies industrial automation systems throughout the entire product or production line life cycle from concept, engineering to production and tuning, helping enterprises upgrade to intelligent manufacturing.

[0034] Furthermore, there are many practical simulation test software and / or simulation test platforms on the market that provide comprehensive simulation test solutions for twin industrial systems. Enterprises can use simulation test software and / or simulation test platforms to test industrial systems through twin industrial systems. In other words, they can simulate different industrial scenarios and test the twin industrial systems in different simulation scenarios to obtain test results, so that the twin industrial systems can be optimized based on the test results.

[0035] It is understandable that enterprises can discover potential logical errors and program defects in actual industrial systems through industrial application testing of twin industrial systems (hereinafter referred to as testing), thereby reducing the trial and error costs when testing in industrial field scenarios and avoiding expensive modification costs in real environments. This can not only reduce the economic losses of enterprises, but also help enterprises verify and improve industrial production efficiency, optimize production processes, and support enterprises in making new decisions. In view of this, it can be seen that testing twin industrial systems is an indispensable and important tool for enterprise intelligent transformation.

[0036] At present, the tests on the twin industrial system are mainly conducted on the OT side of the twin industrial system, and there is a lack of tests on the industrial communication technology (CT) side of the twin industrial system. In other words, the current tests on the twin industrial system will default to the connection of the twin industrial system to the ideal industrial network, and do not consider the actual changes in the industrial network to which the twin industrial system is connected. However, under normal circumstances, a variety of factors will cause changes in the industrial network to which the twin industrial system is connected, and thus the industrial network to which the twin industrial system is connected will most likely not remain in an ideal state. If the twin industrial system is still tested under the assumption that the twin industrial system is connected to the ideal industrial network, the reliability of the test results of the twin industrial system will be low.

[0037] Exemplarily, the actual industrial system that needs to be tested on the industrial communication technology CT side of the twin industrial system may include at least one of the following: 5G+automated guided vehicle (AGV), or 5G+industrial robot.

[0038] In addition, the test on the CT side is usually conducted on the CT side of the on-site industrial system. However, the test on the CT side of the on-site industrial system has high requirements for the industrial site, and requires the establishment of a dedicated test environment in advance. The test takes a long time and the cost of the test is high. In addition, the normal production process of the workshop or production line of the industrial site where the industrial system is located may be affected during the test.

[0039] In view of this, an embodiment of the present application provides a method for testing an industrial system, in which an industrial twin platform constructs a twin industrial system of the business to be tested, and a simulated industrial network construction system constructs a simulated industrial network of the actual industrial system of the business to be tested. After the simulated industrial network construction system transmits the simulated industrial network to the industrial twin platform, the industrial twin platform can test the twin industrial system based on the simulated industrial network. That is to say, in the process of testing the twin industrial system, the industrial twin platform can consider the network conditions of the network in which the actual industrial system of the business to be tested is located, instead of testing the twin industrial system under the assumption that the twin industrial system is connected to an ideal industrial network, thereby improving the reliability of the test results of the twin industrial system.

[0067] In order to solve the problems existing in the above-mentioned prior art, the embodiment of the present application proposes a testing method for an industrial system, which is applied to a testing system for an industrial system, and the testing system for an industrial system includes an industrial twin platform and a simulated industrial network construction system. The testing method for an industrial system described in the embodiment of the present application can improve the accuracy of the test results obtained by testing the twin industrial system as much as possible. Figure 3 As shown, the method includes:

[0074] Optionally, the information included in the scenario design indicators before the construction of the business scenario to be tested can be understood by referring to the above description of the industrial site business scenario information after the construction of the business scenario to be tested, and will not be repeated here.

[0075] It can be understood that in the process of implementing the twin industrial system of the business to be tested recorded in the embodiment of the present application, simulation is performed in multiple dimensions such as production line, equipment location, equipment form, and process flow, so that the twin industrial system constructed based on the simulation results can be kept consistent with the actual industrial system as much as possible.

[0076] It should be understood that the industrial twin platform 101 in the embodiment of the present application can also be referred to as a digital twin platform, or a digital mapping platform, or a digital mirroring platform. In future industrial system simulations, it can also be other names, and the present application does not make any restrictions on this.

[0078] Exemplarily, the simulated industrial network can be any one of the following: a fourth generation mobile communication technology (4G) network, a fifth generation mobile communication technology (5G) network, or a wireless fidelity (WIFI) network. Of course, the above is only an exemplary description of the simulated industrial network. The simulated industrial network can be other communication networks. For example, the global system for mobile communications (GSM) network, and new mobile communication networks that may appear in the future. This application does not impose any restrictions on this.

[0079] It should be understood that the simulated industrial network construction system 102 can also be called a simulated network system. In future industrial system simulations, it can also be called other names, and this application does not impose any limitation on this.

[0080] S303. The simulated industrial network construction system transmits the simulated industrial network to the industrial twin platform. Correspondingly, the industrial twin platform receives the simulated industrial network from the simulated industrial network construction system.

[0081] In some possible implementations, the simulated industrial network construction system can directly transmit the simulated industrial network to the industrial twin platform, or it can transmit the simulated industrial network to the industrial twin platform through other relay devices. The embodiments of the present application do not impose any restrictions on this.

[0082] S304. The industrial twin platform tests the twin industrial system of the business to be tested based on the simulated industrial network.

[0083] Optionally, the implementation process of the above S304 may be: the industrial twin platform may test the product performance, reliability, security, stability and other aspects of the twin industrial system based on the simulated industrial network.

[0084] In the testing method of the industrial system provided in the embodiment of the present application, the industrial twin platform constructs a twin industrial system of the business to be tested, and the simulated industrial network construction system constructs a simulated industrial network of the actual industrial system of the business to be tested. After the simulated industrial network construction system transmits the simulated industrial network to the industrial twin platform, the industrial twin platform can test the twin industrial system based on the simulated industrial network. That is to say, in the process of testing the twin industrial system, the industrial twin platform can consider the network conditions of the network where the actual industrial system of the business to be tested is located, instead of testing the twin industrial system under the assumption that the twin industrial system is connected to the ideal industrial network, thereby improving the reliability of the test results of the twin industrial system.

[0085] The structure of the twin industrial system is described in detail below.

[0086] For example, Figure 4 A schematic diagram of the structure of a twin industrial system provided by an embodiment of the present application is shown in FIG. The twin industrial system may include at least one of the following: at least one device twin component, at least one controller simulation component, at least one system simulation component, at least one inter-device network simulation component, or at least one test rating system. Figure 4 The twin industrial system only shows 4 device twin components, 2 controller simulation components, 3 system simulation components, 2 inter-device network simulation components, and 1 test and evaluation system component.

[0087] Exemplarily, the device twin component 404 may include at least one of the following: a robotic arm, a 3D camera, a motor, or an AGV. Of course, the above is only an exemplary description of the device twin component, and the device twin component may also be other devices, such as a lift. This application does not impose any restrictions on this.

[0088] As some possible implementation methods, the controller simulation component can communicate with external devices through a simulated industrial network. For example, taking the external device as an application server: the controller simulation component can send simulation data to the application server. The application server receives the simulation data from the controller simulation component, and deploys industrial application software, production information system and other software to analyze and process the simulation data to obtain processing results. The application server can determine the corresponding instruction information based on the processing results, and transmit the corresponding instruction information to the controller simulation component. The controller simulation component receives the corresponding instruction information, and controls the operation of the system simulation component based on the instructions sent by the application server.

[0089] Of course, the above is only an exemplary description of the implementation process of the controller simulation component communicating with the external device. The controller simulation component can also communicate with other external devices, for example, the controller simulation component communicates with the touch screen, and this application does not impose any restrictions on this.

[0090] Exemplarily, the application server may include multi-access edge computing (MEC). Of course, the above is only an exemplary description of the application server. The application server may also include other servers, such as a content management system (CMS). The embodiments of the present application do not impose any restrictions on this.

[0091] Exemplarily, the controller simulation component may correspond to a logic control unit in an actual industrial system of the business to be tested. Among them, the logic control unit in the actual industrial system of the business to be tested may include a group of programmable logic controllers (PLC). Furthermore, if there are multiple groups of logic control units in the actual industrial system of the business to be tested, the industrial twin platform can build multiple corresponding simulation control scenarios in the twin industrial system based on the number of logic control units in the actual industrial system of the business to be tested.

[0092] In addition, a large amount of data interaction is required between the system simulation components and the inter-device network simulation components to achieve the accuracy and reliability of the simulation results, thereby supporting in-depth analysis and optimization of the twin industrial system.

[0093] Exemplarily, the data of the above data interaction may include: communication data between devices, system performance data, etc. Of course, the above is only an exemplary description of the data of the above data interaction, and the data of the data interaction may also include other data, such as network status data. This application does not impose any limitation on this.

[0094] Optionally, the test and evaluation system component monitors the operating indicators of the industrial twin platform and compares the operating indicators of the twin industrial system with the operating indicators of the preset actual industrial system. The test and evaluation system component determines the compatibility of the simulated industrial network with the actual industrial system based on the comparison results of the operating indicators of the twin industrial system and the operating indicators of the preset actual industrial system. Among them, if the operating indicators of the twin industrial system are consistent with the operating indicators of the preset actual industrial system, the test and evaluation system component determines that the simulated industrial network is compatible with the actual industrial system; if the operating indicators of the twin industrial system are inconsistent with the operating indicators of the preset actual industrial system, the test and evaluation system component determines that the simulated industrial network is not compatible with the actual industrial system.

[0095] As can be seen from the above description of "S302", the simulated industrial network construction system needs to complete the construction of the simulated industrial network based on multiple devices. Further, the simulated industrial network construction system may include: a network simulation instrument, a sweeper, and a simulator. In other words, the construction of the simulated industrial network can be performed by the network simulation instrument, the sweeper, and the simulator respectively. In view of this, Figure 5 As shown, S302 provided in the embodiment of the present application can be implemented through the following S501 to S505.

[0096] S501. The network simulation instrument simulates the configuration parameters of the communication network to which the actual industrial system is connected to obtain a twin communication network.

[0097] Exemplarily, the configuration parameters of the communication network may include at least one of the following: the communication network Internet Protocol (IP) address, the communication network subnet mask, the communication network gateway, the domain name system (DNS) server address, or the communication network base station equipment parameters. Of course, the above is only an exemplary description of the configuration parameters of the communication network, and the configuration parameters of the communication network may also include other parameters, for example, the configuration parameters of the dynamic host configuration protocol (DHCP) server. The embodiments of the present application do not impose any restrictions on this.

[0098] S502: The network simulation instrument sends the twin communication network to the simulator. Correspondingly, the simulator receives the twin communication network from the network simulation instrument.

[0099] In some possible implementations, the network simulation instrument can send the twin communication network directly to the simulator, or it can send the twin industrial network to the simulator through other relay devices. The embodiments of the present application do not impose any restrictions on this.

[0100] Exemplarily, the network simulation instrument may include a signal source network simulation instrument. Of course, the above is only an exemplary description of the network simulation instrument, and the network simulation instrument may also include other network simulation instruments, such as a network analyzer and a spectrum analyzer. This application does not impose any limitation on this.

[0101] S503, the frequency scanner collects wireless channel parameters in the actual industrial network.

[0102] Exemplarily, the above wireless channel parameters may include: channel capacity, channel bandwidth, delay spread, signal fading, and Doppler effect parameters. Of course, the above is only an exemplary description of wireless channel parameters, and wireless channel parameters may also include other parameters, such as path loss coefficient, path loss index, root mean square delay spread, and angle spread. This application does not impose any restrictions on this.

[0103] S504: The frequency sweeper sends the wireless channel parameters to the simulator. Correspondingly, the simulator receives the wireless channel parameters from the frequency sweeper.

[0104] In some possible implementations, the frequency sweeper may send the wireless channel parameters to the simulator directly, or may send the wireless channel parameters to the simulator via other relay devices, and the embodiments of the present application do not impose any limitation on this.

[0105] S505. The simulator accesses the twin communication network, determines the configuration parameters of the simulated industrial network based on the wireless channel parameters, and constructs the simulated industrial network based on the configuration parameters of the simulated industrial network.

[0106] In addition, optionally, the simulator can also access the actual communication network of the actual industrial system, determine the configuration parameters of the simulated industrial network based on the wireless channel parameters, and build the simulated industrial network based on the configuration parameters of the simulated industrial network. The actual communication network can include a core network and a base station.

[0107] Optionally, the implementation process of the above-mentioned simulator determining the configuration parameters of the simulated industrial network based on the wireless channel parameters can be: the simulator constructs a wireless channel model through the wireless channel characteristics of the network environment of the actual industrial site, and loads the wireless channel model to construct a simulated industrial network based on the configuration parameters of the simulated industrial network.

[0108] As can be seen from the above description of "S303", the simulated industrial network construction system transmits the simulated industrial network to the industrial twin platform. Furthermore, the simulated network construction system also includes: a forwarding unit, that is, the simulated industrial network construction system can transmit the simulated industrial network to the industrial twin platform through the forwarding unit. In view of this, Figure 6 As shown, S303 provided in the embodiment of the present application can be implemented through S601.

[0109] S601. The simulator transmits the simulated industrial network to the industrial twin platform through the forwarding unit.

[0110] It can be understood that the simulator transmits the simulated industrial network to the industrial twin platform through the forwarding unit, which can ensure the speed of data transmission from the simulated industrial network to the industrial twin platform, and thus ensure that the industrial twin platform can obtain the latest test results in time, so as to more accurately reflect the adaptability of the simulated industrial network and the twin industrial system.

[0111] As can be seen from the above descriptions of "S302" or "S505", the simulator can complete the establishment of the simulated industrial network based on the configuration parameters of the simulated industrial network. Among them, the simulated industrial network construction system also includes: a network adjustment system, that is, the simulator and the network adjustment system can complete the establishment of the simulated industrial network. In view of this, Figure 7 As shown, S302 or S505 provided in the embodiment of the present application can be implemented through the following S701 to S704.

[0112] S701. The simulator constructs an initial industrial network of an actual industrial system of a service to be tested based on configuration parameters of the simulated industrial network.

[0113] Optionally, simulation software is installed in the simulator. In this case, the implementation process of S701 may be that the simulator inputs configuration parameters of the simulated industrial network into the simulation software, and uses the simulation software to build an initial industrial network of the actual industrial system of the service to be tested.

[0114] S702: The simulator sends an initial industrial network to the network regulation system. Correspondingly, the network regulation system receives the initial industrial network from the simulator.

[0115] In some possible implementations, the simulator may directly transmit the initial industrial network to the network regulation system, or may transmit the initial industrial network to the network regulation system through other relay devices, and the embodiments of the present application do not impose any restrictions on this.

[0116] S703: The network adjustment system determines a network error.

[0117] The network error is used to indicate the error between the transmission parameters of the initial industrial network and the transmission parameters of the actual industrial network.

[0118] Optionally, the transmission parameters of the actual industrial network can also be monitored by an external instrument, for example, the external instrument can be a network simulator. Of course, the above is only an exemplary description of an external instrument for determining a network error, and the external instrument for determining a network error can also include other devices, for example, a network tester. This application does not impose any restrictions.

[0119] Further, optionally, if the network error has no effect on the implementation of building the simulated industrial network, the network regulation system may omit the step of determining the network error.

[0120] S704: The network adjustment system corrects the initial industrial network based on the network error to obtain a simulated industrial network.

[0121] Optionally, the implementation process of the above S704 may be: the network adjustment system may superimpose interference on the initial industrial network based on the network error to obtain a simulated industrial network.

[0122] As can be seen from the above description of "S703", the network regulation system can determine the network error based on the first transmission parameter and the second transmission parameter. Further, the network regulation system includes a network monitor, that is, the network monitor can determine the network error based on the first transmission parameter and the second transmission parameter. In view of this, Figure 8 As shown, S703 provided in the embodiment of the present application can be implemented through the following S801.

[0123] S801. The network monitor monitors the initial industrial network and the actual industrial network, obtains transmission parameters of the initial industrial network and the actual industrial network respectively, and compares the transmission parameters of the initial industrial network with the transmission parameters of the actual industrial network to determine network errors.

[0124] Optionally, the transmission parameters of the initial industrial network may be transmission parameters during data transmission between the forwarding unit and the industrial twin platform through the initial industrial network. The transmission parameters of the actual industrial network may be transmission parameters during data transmission between the gateway and the actual industrial system through the actual industrial network.

[0125] Exemplarily, the transmission parameters of the initial industrial network may include at least one of the following: delay, jitter, or reliability.

[0126] It should be understood that the parameters that may be included in the transmission parameters of the actual industrial network for shutting down may be understood by referring to the description of the parameters included in the transmission parameters of the initial industrial network, and will not be repeated here.

[0127] Exemplarily, the transmission parameter delay can be represented by T, the transmission parameter jitter can be represented by D, the transmission parameter bandwidth can be represented by B, and the transmission parameter reliability can be represented by R. This application does not impose any limitation on this.

[0128] Optionally, the network monitor compares the transmission parameters of the initial industrial network with the transmission parameters of the actual industrial network, and the implementation process of determining the network error can be: the network monitor determines the difference between the transmission parameters of the actual industrial network and the transmission parameters of the initial industrial network as the network error. The difference between the transmission parameters of the actual industrial network and the transmission parameters of the initial industrial network is greater than 0.

[0129] In combination with the above examples, the network error determined by the network monitor may include delay error, jitter error, and reliability error as examples. Among them, the delay of the initial industrial network can be represented by T1, the jitter can be represented by D1, and the reliability can be represented by R1. The delay of the actual industrial network can be represented by T2, the jitter can be represented by D2, and the reliability can be represented by R2. That is to say, the delay error determined by the network detector can be the difference between T1 and T2, the jitter error can be the difference between D1 and D2, and the reliability difference can be the difference between R1 and R2.

[0130] As can be seen from the above description of "S704", the network adjustment system can correct the initial industrial network based on the determined network error. Furthermore, the network adjustment system also includes a network damage meter, that is, the network damage meter can complete the construction of the simulated industrial network based on the determined network error. In view of this, Fig. 9 As shown, the embodiment S704 of the present application can be implemented through the following S901 to S902.

[0131] S901: The network monitor sends network errors to the network damage instrument. Correspondingly, the network damage instrument receives the network errors from the network monitor.

[0132] In some possible implementations, the network monitor can send network errors directly to the network damage instrument, or send network errors to the network damage instrument through other relay devices, or send network errors to the network damage instrument through a cloud synchronization service. The embodiments of the present application do not impose any restrictions on this.

[0133] S902. The network damage instrument adds a disturbance signal to the initial industrial network based on the network error to obtain a simulated industrial network.

[0134] It is understandable that the network damage instrument superimposes interference on the initial industrial network based on network errors, ensuring the consistency of the transmission parameters of the simulated industrial network with the transmission parameters of the actual industrial network as much as possible. In other words, the network environment of the simulated industrial network can be made highly consistent with the network environment of the actual industrial network. When the industrial twin platform is being tested, the twin industrial system is in a network environment that is highly consistent with the actual industrial network, which improves the reliability of the test results.

[0135] It is understandable that the above-mentioned testing method of the industrial system can be implemented by the testing device of the industrial system.
