[0029] In the field of industrial production, the increasing requirements for industrial product quality and production efficiency and the increasing demand for the integration of multifunctional systems have prompted the electromechanical systems of related industries to develop in an increasingly complex and large-scale direction to meet the integration requirements of multiple systems and equipment and ensure that the various systems and equipment can work together efficiently. At the same time, since the electromechanical system may be composed of multiple subsystems and equipment with different functions, and the equipment that makes up the electromechanical system may come from different manufacturers in different regions, the assembled electromechanical system may have many problems, such as whether the functions of each device that constitutes the electromechanical system can meet the functional requirements, whether the interfaces between equipment from different manufacturers are compatible, and the internal failures and safety hazards of the electromechanical system. Therefore, the verification of the electromechanical system with multiple subsystems and equipment with different functions is extremely important.

[0030] In the semi-physical verification method of electromechanical systems, simulation models and some physical objects (physical objects are some subsystems or devices in the electromechanical system to be verified) are usually concentrated in the same place, and a real-time network environment is built to realize the interactive transmission of data. Furthermore, the real-time simulator runs the simulation model to generate simulation data, and then transmits the simulation data of the real-time simulator to each test device involved in the verification through the real-time network. After that, the test device generates device parameters after receiving the corresponding device data and performing operations, and then uses the real-time network to pass the device parameters to the entire verification system, so that the verification system can analyze and evaluate the state after the operation is performed. However, when the electromechanical system involves multiple complex subsystems and devices, semi-physical verification of it requires the subsystems or devices involved to be transported together from different places, and the corresponding physical test benches need to be built in a centralized manner, which not only has great transportation difficulties, but also has high time and financial costs. Therefore, there is an urgent need for a technology that can perform semi-physical verification of electromechanical systems in a remote environment to overcome the problem of high cost of semi-physical verification methods for electromechanical systems.

[0031] The present application provides a remote semi-physical verification method for an electromechanical system, which is applied to a remote semi-physical verification system for an electromechanical system, and can realize semi-physical verification of the electromechanical system in a remote environment at a low cost.

[0032] Specific embodiments are given below to introduce the technical solution of the present application in detail.

[0033] Figure 1 This is a flow chart of the remote semi-physical verification method for an electromechanical system provided in Example 1 of the present application. The remote semi-physical verification method for an electromechanical system provided in this embodiment is applied to a remote semi-physical verification system.

[0034] Figure 2 This is a schematic diagram of a remote semi-physical verification system shown in an exemplary embodiment of the present application. Figure 2 The off-site semi-physical verification system for electromechanical systems is used to verify the system to be verified; the off-site semi-physical verification system includes an integrated management computer, a server, and multiple physical devices among all the physical devices included in the system to be verified; the multiple physical devices and the integrated management computer are respectively connected to the server through 5G communication technology; the multiple physical devices are distributed in different regions; the integrated management computer is configured with simulation models corresponding to each other physical device of the system to be verified except the multiple physical devices; each simulation model simulates the behavior of the corresponding physical device to constitute a virtual device of the physical device; the multiple physical devices and the virtual devices constitute the verification system corresponding to the system to be verified; the integrated management computer is also configured with a controller model; the controller model is used to verify the verification system based on a specified verification task.

[0035] For further information, please also refer to Figure 1 and Figure 2 The off-site semi-physical verification method of the electromechanical system comprises:

[0036] S101. The integrated management computer runs the controller model to obtain the real state parameters required for the current operation cycle from the server; wherein the real state parameters are the state parameters of the multiple designated devices themselves reported to the server; and the controller model is provided with multiple operation cycles.

[0037] For details, please refer to Figure 2 The off-site semi-physical verification system for electromechanical systems includes a comprehensive management computer, a server, and multiple physical devices among all the physical devices included in the system to be verified.

[0038] Among them, the integrated management computer is configured with simulation models and controller models corresponding to various other physical devices in the system to be verified (the system to be verified is an electromechanical system to be verified that actually exists in reality) except for multiple physical devices.

[0039] It should be noted that multiple physical devices are real devices in the system to be verified. These devices can be distributed in different regions and connected to the server through 5G communication technology. Furthermore, for other physical devices in the system to be verified except the above-mentioned physical devices, simulation models of these other physical devices are configured inside the comprehensive management computer, and the behaviors of the corresponding physical devices are simulated through these simulation models to constitute virtual devices of these physical devices.

[0040] It should be noted that the integrated management computer is also configured with a controller model, and the controller model can verify the verification system based on the specified verification task. It should be noted that the specified verification task is set according to actual needs and is not limited in this application. For example, in one embodiment, the specified verification task may be a compatibility verification task; in another embodiment, the specified verification task may be a functional verification task; in yet another embodiment, the specified verification task may be a security verification task.

[0041] Furthermore, as the core computing unit of the system, the integrated management computer can control the entire verification process, manage verification tasks, and coordinate data exchange between various devices. On the one hand, the integrated management server needs to receive large-capacity data from the server, use the analysis and decomposition strategy to perform high-speed calculations, and transmit the calculated simulation data to the corresponding simulation model for processing; on the other hand, the control instructions must be transmitted to each physical device through the server within the preset calculation cycle. Therefore, the integrated management computer needs relatively powerful computing and data processing capabilities, and at the same time, it needs to communicate quickly with the physical devices to meet the verification needs that require real-time processing of large amounts of data and control instructions.

[0042] It should be noted that the composition of the integrated management computer can be selected according to actual needs, and is not limited in this application. For example, in one embodiment, the integrated management computer can be implemented by a powerful computer to meet the computing power and data processing capabilities required during the verification process; in another embodiment, the integrated management computer can be implemented by a computer cluster composed of multiple computers to further improve the processing power through distributed computing and resource sharing, thereby meeting the computing power and data processing capabilities required during the verification process.

[0043] Furthermore, the server serves as a 5G cloud system, and the 5G cloud system serves as the server network port of the cloud service, with the characteristics of low latency and massive data communication, and can process a large amount of data in a short time. Therefore, the 5G cloud system is used as a large-capacity data storage and transit transmission hub for multiple physical devices and integrated management computers in different locations. In this way, through 5G communication technology, real-time data transmission between the server and the integrated management computer, and between the server and multiple physical devices in different locations can be realized.

[0044] It should be noted that each physical device is configured with a 5G communication client; the integrated management computer is configured with a 5G communication client; the server is configured with a 5G communication server; each physical device and the integrated management computer communicate with the 5G communication server on the server through the 5G communication client.

[0045] Furthermore, the physical device and the server communicate based on an agreed end-to-end special handshake protocol; the integrated management computer and the server communicate based on an agreed end-to-end special handshake protocol.

[0046] In this way, the communication between physical devices and servers, and between servers and integrated management computers can be based on the agreed end-to-end special handshake protocol, using the configured 5G client to perform stable, fast, and low-latency 5G communication, ensuring the efficiency, real-time nature, and security of data transmission interaction.

[0047] It should be noted that the end-to-end special handshake protocol is set according to actual needs and is not limited in this application.

[0048] It is understandable that, in a possible implementation, when the physical device and the server, or the server and the integrated management computer communicate based on the agreed end-to-end special handshake protocol to transmit data, the data can also be encrypted and decrypted according to the predetermined encryption and decryption rules. It should be noted that the encryption and decryption rules can be set according to actual needs, and are not limited in this application.

[0049] Specifically, in this step, the integrated management computer runs the internal controller model and obtains the real state parameters required for the current operation cycle from the server.

[0050] It should be noted that the real state parameters are the state parameters of the multiple physical devices reported to the server. Specifically, the controller model is provided with multiple operation cycles, and the physical devices are verified in each of the multiple operation cycles. In each operation cycle, the physical device that needs to be verified will pass its own state parameters (for example, in one embodiment, its own state parameters may include parameters such as rotation speed, pressure, temperature, valve opening, etc.) to the server, and then pass them to the integrated management computer through the server.

[0051] Furthermore, the specific cycle duration of the operation cycle is set according to actual needs and is not limited in the present application. For example, in one embodiment, the specific cycle duration of the operation cycle may be 20 ms.

[0052] S102. The integrated management computer runs the simulation model corresponding to the current cycle, so that the simulation model determines the simulation parameters of the virtual device based on the real state parameters of the current demand, and the controller model generates control instructions for the specified device involved in the current operation cycle based on the simulation parameters.

[0053] Specifically, in the current operation cycle, the physical device transmits its own status information to the integrated management computer through the server, while running the simulation model inside the integrated management computer. The simulation model determines the simulation parameters of the virtual device corresponding to the simulation model based on the real state parameters required for the current cycle, and then the controller model generates control instructions for the specified device involved in the current operation cycle based on the simulation parameters of the virtual device, so as to make the necessary operational adjustments to the specified device.

[0054] It should be noted that the designated devices include physical devices and virtual devices involved in the current cycle of the controller model operation.

[0055] Optionally, in one operation cycle, when multiple simulation models need to be run, the integrated management computer runs the multiple simulation models in parallel.

[0056] S103, the integrated management computer transmits the control instructions for the virtual device to the simulation model corresponding to the virtual device, and reports the control instructions for the multiple physical devices to the server; wherein the control instructions for the multiple physical devices carry the timestamp corresponding to the current operation cycle.

[0057] In this step, after the controller model in the integrated management computer generates the control instruction, the control instruction for the virtual device is transmitted to the simulation model corresponding to the virtual device, and at the same time, the control instruction for multiple physical devices is reported to the server.

[0058] It should be noted that the control instructions for multiple physical devices contain a timestamp corresponding to the current operation cycle. For example, if the control instructions for multiple physical devices correspond to the first operation cycle, then the control instructions for multiple physical devices carry the following information: timestamp time1. For another example, if the control instructions for multiple physical devices correspond to the second operation cycle, then the control instructions for multiple physical devices carry the following information: timestamp time2, where time1 is used to indicate that the control instruction referred to by the timestamp is a control instruction in the first operation cycle among multiple operation cycles, and time2 is used to indicate that the control instruction referred to by the timestamp is a control instruction in the second operation cycle among multiple operation cycles.

[0059] It should be noted that after the simulation model completes a calculation cycle, the integrated management computer will share the control instructions with the timestamp of this moment through the 5G communication client loaded in the integrated management computer. The 5G communication client uses the 5G communication technology of the agreed end-to-end special handshake protocol to share it in real time to the 5G communication server. At this time, the server performs time-sharing and partitioning storage according to the timestamp. In this way, the client on the remote device can obtain the control instructions of different zones at the same time according to the agreed end-to-end special handshake protocol with the server, which can improve the real-time performance.

[0060] S104. The server stores the control instructions for each designated physical device in a partition corresponding to the designated physical device; wherein the control instructions in different operation cycles are stored in different locations.

[0061] Specifically, in this step, the large-capacity data storage function of the server is utilized to store the control instructions for multiple designated physical devices from the integrated management computer into the partitions corresponding to the designated physical devices. Different physical devices are partitioned by the server, and the data of different physical devices are stored in different partitions. In addition, the control instructions under different operation cycles are stored in different locations, that is, they are stored in partitions and in parallel.

[0062] It should be noted that, in a possible implementation, storage space device1 is allocated to entity device 1, and control instructions in multiple operation cycles of entity device 1 are allocated to storage space device1. At the same time, in storage space device1, sub-storage spaces corresponding to the number of operation cycles are set to store the control instructions corresponding to the entity device in each operation cycle, respectively, wherein the partition name of the sub-storage space is the same as the timestamp contained in the control instruction. For example, the partition name of the control instructions of the first operation cycle of entity device 1 stored in the server is device1-time1, and the partition name of the control instructions of the second operation cycle of entity device 2 stored in the server is device2-time2.

[0063] S105. Each physical device periodically obtains the control instruction in the current operation cycle from the corresponding partition on the server, and responds to the control instruction.

[0064] In this step, each physical device periodically obtains the control instruction under the current operation cycle from the corresponding partition in the server, and executes the operation task contained in the control instruction.

[0065] It should be noted that each physical device obtains control instructions from the server in the same cycle, which is less than one computing cycle. In this way, each physical device will obtain control instructions at a consistent rhythm in the same cycle, ensuring coordination and synchronization between the physical devices. Furthermore, the cycle for each physical device to obtain control instructions is less than one computing cycle, which allows the physical device to respond to control instructions more quickly and perform specified operations, thereby improving the overall response speed of the system.

[0066] Furthermore, each physical device is configured with a microcontroller; the microcontroller on each physical device is connected to the 5G communication client on the physical device via a network cable or a serial port; the microcontroller is used to serve as a controller on the physical device to independently control the physical device.

[0067] It should be noted that the microcontroller on each physical device can parse the control instructions from the server, and control the physical device to perform corresponding operations based on the results of the analysis. Furthermore, the microcontroller and the 5G communication client on the physical device can be connected via a network cable or serial port. In this way, the 5G network can be used to quickly receive control instructions from the server and perform corresponding operations. In the event of communication interruption, the serial port can be used to receive control instructions and control the physical device to perform corresponding operations, thereby improving the effectiveness and reliability of the system.

[0068] S106: After responding to the control instruction, each physical device reports its own real state parameters to the server.

[0069] In this step, after the microcontroller on each physical device controls the physical device to respond to the control instruction and perform corresponding operations, the real status parameters of the physical device are reported to the server through the 5G communication client configured on each physical device.

[0070] S107. The server stores the real status parameters of each physical device in the partition corresponding to the physical device, so that the integrated management computer can obtain the required real status data from the server in the next operation cycle.

[0071] In this step, the server is used to store the real state parameters of each physical device in the partition corresponding to the physical device, so that at the beginning of the next operation cycle, the integrated management computer can obtain the real state data of multiple physical devices after the previous operation cycle from the server, and analyze and obtain the control instructions for multiple physical devices in the current operation cycle. For example, corresponding to physical device 1, the control instructions of physical device 1 in the first operation cycle are stored in the device1-time1 partition of the server, and then the real state parameters of physical device 1 after executing the control instructions in the first operation cycle are stored in the device1-time1-state1 partition of the server. In this way, in the second operation cycle, the integrated management computer can find the real state data of physical device 1 after executing the control instructions of the first operation cycle in the device1-time1-state1 partition of the server, and analyze and obtain the control instructions that physical device 1 needs to perform in this operation cycle.

[0072] The semi-physical verification method for an electromechanical system provided in this embodiment, on the one hand, replaces part of the physical equipment with a virtual simulation model, aggregates the distributedly deployed physical equipment, and uses an integrated management computer and 5G communication technology to collaboratively combine the verification loop, which can not only reduce the physical hardware requirements and maintenance costs, but also eliminate the need for centralized deployment of physical equipment. Equipment in different regions can be used to simultaneously participate in the verification, which reduces the overhead caused by equipment transportation or centralized verification and can reduce the cost of verification; on the other hand, the verification method adopts a distributed multi-operation cycle design, which ensures high-precision synchronization of control instructions and equipment responses through real-time updated real state parameters and timestamps, and can provide reliable verification results; on the third hand, the remote semi-physical verification system can flexibly add or remove physical equipment, and the simulation model can be dynamically adjusted with the verification task, with strong adaptability, and can support verification tasks under a variety of complex working conditions; on the fourth hand, the remote semi-physical verification system can realize the collaborative work of physical equipment and integrated management computers in different regions, support cross-regional remote verification, and reduce the coordination difficulties caused by geographical dispersion.

[0073] Figure 3 This is a schematic diagram of a remote semi-physical verification system shown in another exemplary embodiment of the present application. Please refer to Figure 3 The off-site physical verification system provided in this embodiment is used to perform semi-physical verification on the electric fuel pump in the energy integrated management device PTMU; the multiple physical devices include an ignition component, an electric fuel pump and a solenoid valve; the simulation model includes a system model of the PTMU; the system model does not include simulation models of the ignition component, the electric fuel pump and the solenoid valve; further, at this time, the off-site semi-physical verification method includes:

[0074] The integrated management computer runs the controller model to obtain from the server an ignition parameter used to characterize whether the ignition is completed, a position parameter used to characterize the action position of the solenoid valve, and a fuel flow parameter;

[0075] The integrated management computer runs the system model, the system model calculates the rotation speed, exhaust temperature, and compressor margin of the PTMU based on the ignition parameter, the position parameter, and the fuel flow parameter, and the controller model determines the ignition instruction, the solenoid valve position target demand instruction, and the electric fuel pump fuel supply target demand instruction according to the rotation speed, the exhaust temperature, and the compressor margin of the PTMU;

[0076] The integrated management computer reports the ignition instruction with the timestamp corresponding to the current operation cycle, the solenoid valve position target demand instruction with the timestamp, and the electric fuel pump fuel supply target demand instruction with the timestamp to the server;

[0077] The server stores the ignition instruction, the solenoid valve position target requirement and the capacitor fuel pump fuel supply target requirement instruction in a time-division and partition-based manner according to the timestamp and the partitions corresponding to each physical device;

[0078] The ignition assembly, the electric fuel pump and the solenoid valve obtain instructions corresponding to the partition at the same time from the server and respond to the instructions;

[0079] The ignition component, the electric fuel pump and the solenoid valve respectively report the ignition parameters used to characterize whether ignition is on, the fuel flow parameters, and the position parameters used to characterize the position of the solenoid valve to the server to achieve a closed loop of data.

[0080] The semi-physical verification method provided in this embodiment is very suitable for the verification needs of modern complex electromechanical systems in multiple scenarios and multiple regions. It also reduces verification costs, significantly shortens the R&D cycle, and improves the reliability and efficiency of system development.

[0081] The remote semi-physical verification method for the electromechanical system provided in this embodiment runs the controller model on the integrated management computer to obtain ignition parameters, position parameters for characterizing the action position of the solenoid valve, and fuel flow parameters from the server. Further, the system model inside the integrated management computer is run to calculate the key operating parameters such as the rotation speed, exhaust temperature, and compressor margin of the PTMU based on the ignition parameters, position parameters, and fuel flow parameters. Afterwards, the controller model generates an ignition instruction, a solenoid valve position target instruction, and a fuel pump supply target instruction based on these operating parameters, and adds a timestamp of the current operation cycle to the instruction, which is uploaded to the server in real time through 5G communication technology. The timestamps on the physical devices and control instructions are stored in the server in a time-sharing and partitioned manner. Furthermore, the physical devices such as the ignition component, the electric fuel pump and the solenoid valve obtain the corresponding control instructions from the server according to the timestamps. The control instructions are parsed by the microcontroller on each physical device and the physical device is controlled to perform the corresponding operation according to the control instructions. The real state parameters such as the ignition state, the actual fuel flow and the solenoid valve position after the operation are fed back to the server in real time and stored in the storage location under the current operation cycle, so that the comprehensive management computer can read these real state parameters from the server in the next operation cycle, forming a data closed loop, and realizing accurate control and real-time monitoring of the equipment. In this way, the reliability and stability of the PTMU system can be accurately and efficiently verified when some devices in the PTMU are semi-remote, which greatly reduces the cost of verification while improving the convenience of the verification process.
