[0035] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0036] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0037] The main solution of the embodiment of the present application is: receiving a simulation signal sent by a controller; generating a control signal according to the simulation signal through a control model of the automation system; and executing a simulation action according to the control signal when receiving the control signal through a system model of the automation system.

[0038] Therefore, the present application provides a solution, which controls the system model of the automation system to perform simulation actions according to the simulation signal sent by the controller through the control model of the automation system. After the simulation, not only the automation system can be analyzed and optimized according to the simulation results of the system model, but also the control logic of the controller can be analyzed and optimized according to the simulation results. This solves the technical problem of how to verify the control logic of the controller when simulating the automation system, and improves the applicability and reliability of the automation system simulation.

[0039] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, an automation system simulation device, etc. The following takes the automation system simulation device as an example to illustrate this embodiment and the following embodiments.

[0040] First, the embodiment of the present application provides an automation system simulation system, such as Figure 1 As shown, the automation system simulation system may include:

[0041] The automation system simulation device 30 as described above;

[0042] The controller 20 is used to send a simulation signal to the automation system simulation device 30 .

[0043] It should be noted that the automation system may be a mine automation system, and the controller 20 may be a programmable logic controller (PLC). The automation system simulation system may further include a host computer 10 and a human-computer interaction device 40, wherein the host computer 10 may send simulation instructions to the controller according to a manual operation of the user on the human-computer interaction device 40, wherein the human-computer interaction device 40 may include at least one of a handle, a keyboard, and a display screen.

[0044] It is understandable that the host computer 10 and the automation system simulation device 30 can be the same computing service device or different computing service devices. Specifically, the automation system simulation method is as follows.

[0045] Based on this, the present application embodiment provides an automation system simulation method, referring to Figure 2 , Figure 2This is a flowchart of the first embodiment of the automation system simulation method of the present application.

[0046] In this embodiment, the automation system simulation method may include steps S100 to S300:

[0047] Step S100, receiving a simulation signal sent by a controller.

[0048] It should be noted that the simulation signal may be a signal representing the system action behavior or system action characteristics of the automation system. In the process of simulating the automation system, the simulation signal may control the system model to simulate the real system action behavior of the automation system, so as to test, analyze and optimize the automation system without actual hardware. The controller may be a physical controller in the automation system, and may include controllers of different subsystems in the automation system.

[0049] It is understandable that the simulation signal can be generated by the controller according to the received simulation instruction. The simulation instruction can be generated by the human-computer interaction device in the automation system simulation system according to the user operation. The simulation instruction can also be a trigger instruction. In this case, the controller can generate at least one simulation signal according to the trigger instruction and / or its own control logic to control the corresponding system model to perform the simulation action.

[0050] In a feasible implementation manner, step S100 may include: receiving a simulation signal sent by the controller via a user datagram protocol.

[0051] It should be noted that the User Datagram Protocol (UDP) can provide data transmission services between the controller and the automation system simulation device.

[0052] Step S200, generating a control signal according to the simulation signal through a control model of the automation system.

[0053] Step S300 , when a control signal is received, a simulation action is performed according to the control signal by the system model of the automation system.

[0054] It should be noted that the system model can be a dynamic simulation model of the automation system. In the mine automation system, the dynamic simulation model can include a kinetic model, a mechanical system model, a hydraulic system model, etc. The control model can be a mathematical model that describes the dynamic behavior of the system. One system model corresponds to one control model, and different system models are controlled by control signals output by their corresponding control models.

[0055] In a specific implementation, after receiving a simulation signal, the automation system simulation device can send the simulation signal to a control model corresponding to the simulation signal, generate a control signal based on the simulation signal through the control model, and send the control signal to the corresponding system model to control the system model to perform simulation actions.

[0056] It is understandable that after the system model performs the simulation action, the simulation result can be fed back to the automation system simulation device, and the automation system simulation device verifies and analyzes the control logic of the controller according to the simulation result, so that the user can optimize the control logic of the controller according to the control logic analysis result. In addition, the automation system simulation device can also feed back the simulation result to the human-computer interaction device, and display the simulation result to the user through the human-computer interaction device, so that the user can verify, analyze and optimize the control logic of the controller according to the simulation result.

[0057] In a feasible implementation manner, after step S300, the automation system simulation method may further include: receiving a simulation result signal fed back by the system model through the control model; and analyzing the control logic of the controller according to the simulation result signal to obtain a control logic analysis result.

[0058] It should be noted that the automation system simulation device also has a data analysis function. When the control model receives the simulation result signal fed back by the corresponding system model, the automation system simulation device can verify whether the control logic of the controller meets the requirements by comparing the simulation result corresponding to the simulation result signal with the preset simulation result corresponding to the simulation signal, and obtain the control logic analysis result, so that the user can optimize the control logic of the controller according to the control logic analysis result. Among them, the preset action execution result is determined according to the simulation requirement corresponding to the simulation signal.

[0059] In one example, the controller may include a second-floor table controller, a drill surface controller, and an iron roughneck controller, the simulation signal may include a second-floor table control signal, a drill surface drive signal, and an iron roughneck feedback signal, and the simulation result signal may include a second-floor table feedback signal, a drill surface feedback signal, and an iron roughneck feedback signal. In the actual simulation process, the second-layer platform controller, the drill surface controller and the iron roughneck controller generate the second-layer platform control signal, the drill surface drive signal and the iron roughneck feedback signal respectively, and send the second-layer platform control signal, the drill surface drive signal and the iron roughneck feedback signal to the control model through UDP. After the system model executes the simulation action according to the second-layer platform control signal, the drill surface drive signal and the iron roughneck feedback signal, the control model receives the second-layer platform feedback signal, the drill surface feedback signal and the iron roughneck feedback signal returned by the system model. Finally, the automation system simulation equipment analyzes the control logic of the second-layer platform controller, the drill surface controller and the iron roughneck controller according to the second-layer platform feedback signal, the drill surface feedback signal and the iron roughneck feedback signal received by the control model, and obtains the control logic analysis results of the second-layer platform controller, the drill surface controller and the iron roughneck controller.

[0060] In addition, it is understandable that the automation system simulation equipment can also analyze and optimize each control model and each system model according to the simulation result signal. Among them, for each control model, the automation system simulation equipment can analyze and optimize the control path of the control model through the simulation result signal. For the hydraulic system model, the automation system simulation equipment can analyze and optimize the action characteristics of the hydraulic components according to the simulation result signal to guide the selection of the hydraulic valve group. For the mechanical system model, the automation system simulation equipment can analyze the load characteristics of the mechanical system model according to the simulation result signal to guide the mechanical system design.

[0061] In a feasible implementation manner, before step S100, the automation system simulation method may further include: generating a control model according to control parameters of the automation system by using a simulation tool; generating a system model according to system parameters of the automation system by using a simulation tool.

[0062] It should be noted that the simulation tool can be a visual simulation tool, and the control parameters and system parameters of the automation system can be input into the automation system simulation device by the user through the human-computer interaction device. Among them, the simulation tool can include at least one of adams, AMEsim and simulink. The control model can be generated by simulink, the hydraulic system model can be generated by AMEsim, and the mechanical system model can be generated by adams.

[0063] It is understandable that before performing simulation, the user may build a control model and a system model of the automation system in the automation system simulation device in advance through the human-computer interaction device.

[0064] In a feasible implementation, step S200 may include: using a system model of the automation system, when a function model interface corresponding to the system model receives a control signal, executing a simulation action according to the control signal.

[0065] It should be noted that the Functional Mock-up Interface (FMI) is an open standard for simulation model exchange and joint simulation. FMI allows models to be exchanged and integrated between different simulation tools.

[0066] It is understandable that, since the control model and the system model are built through different simulation tools, in order to realize data transmission between the control model and the system model, before simulation, the user can also configure the functional model interface of the control model and the functional model interface of the system model on a unified simulation platform in the automation system simulation device through the human-computer interaction device, so that after the control model generates a control signal, the control signal is sent to the corresponding functional model interface of the system model through the functional model interface of the control model, and the control system model performs simulation actions according to the control signal received by the corresponding functional model interface. Among them, the user can configure the functional model interface of the control model and the functional model interface of the system model through the model bus.

[0067] In a feasible implementation, after step S300, the automation system simulation method may further include: receiving the simulation result signal fed back by the system model through the control model, and forwarding the simulation result signal to the controller, so that the controller determines the next simulation signal when receiving the simulation result signal; receiving the next simulation signal, and taking the next simulation signal as the simulation signal, and returning to execute step S200.

[0068] It should be noted that during the development phase of the automation system, multiple system models of the automation system need to be simulated to analyze and optimize the automation system.

[0069] Therefore, this embodiment determines the simulation order of multiple system models according to the actual simulation requirements of multiple system models. After the system model feeds back the simulation result signal to the corresponding control module, when the control module receives the simulation result signal through automated system simulation, the next simulation signal of the next system model to be simulated is determined according to the simulation signal corresponding to the simulation result signal and / or the simulation result signal, combined with the simulation order, and the next system model is controlled to perform simulation, thereby realizing the linkage simulation of multiple system models, so that the user only needs to send a trigger instruction to the controller to trigger the linkage simulation of multiple system models.

[0070] Therefore, this embodiment provides an automation system simulation method, which controls the system model of the automation system to perform simulation actions according to the simulation signal sent by the controller through the control model of the automation system, so that after the simulation, not only the automation system can be analyzed and optimized according to the simulation results of the system model, but also the control logic of the controller can be analyzed and optimized according to the simulation results, which solves the technical problem of how to verify the control logic of the controller when simulating the automation system, and improves the applicability and reliability of the automation system simulation. Compared with verifying the automation system through physical experiments, the automation system simulation method of this embodiment can also shorten the product development cycle and reduce the test costs and debugging time of physical experiments.

[0071] In addition, this embodiment can also perform simulation analysis on the hydraulic system in the mine automation system, optimize the action characteristics of the hydraulic system, and guide the selection of the hydraulic valve group in the hydraulic system.

[0072] In addition, this embodiment also implements one-key linkage simulation of multiple system models by feeding back the simulation result signal of the system model to the controller, triggering the controller to determine the next simulation signal.

[0073] The present application provides an automation system simulation device, which includes: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute the automation system simulation method in the above-mentioned embodiment 1.
