[0037] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0038] In view of the technical problems existing in the prior art, the present application applies the virtualization technology to the testing of the simulator system. Specifically, the computing, storage and network physical resource of one physical server are pooled into corresponding virtual resource pools, then the virtual resources are assembled into virtual computers of various specifications according to application requirements, and a virtual network switch is created. Moreover, the virtual computers are connected into a simulator system by using the virtual network switch, a virtual network system of a simulator testing platform is assembled, and the deployment and running of the simulator system and application software are performed based on the virtual network system.

[0039] Figure 2 is a flowchart of a running environment construction method of a simulator system according to an embodiment of the present application. The running environment construction method of the simulator system in this embodiment is applied to a physical server, and specifically includes:

[0040] Step S10. Receiving configuration requirements of the simulation machine system inputted by a user;

[0041] In this step, it is to be explained that when selecting a physical server, a physical server with appropriate configuration should be selected according to the overall hardware resource requirements of the simulation machine system, for example, a physical server with appropriate configuration is selected from the aspects of computing, storage and IO performance, etc. Moreover, virtual software needs to be installed on the physical server. Then, the hardware configuration, resource occupation of each computer in the simulation machine system constructed by using the traditional running environment construction method, and the network structure are collected, and according to the collected information, the configuration requirements are inputted to the physical server.

[0042] Step S20. According to the configuration requirements, at least one virtual network switch and a plurality of virtual computers with different specifications are created by using a computing virtualization technology, wherein the virtual computers include a virtual operation station, a process model virtual server (used for simulating equipment of a nuclear power plant, for example, a pipeline), a control logic virtual server, and of course, other types of virtual servers, a virtual engineer station, etc. can also be included;

[0043] In this step, according to the resource configuration requirements of each computer in the traditional test platform, such as computing, memory, external storage, network interface, etc., the corresponding virtual computer is created and connected with the corresponding virtual network switch. Moreover, according to the number of networks of the simulation machine system, a corresponding number of virtual switches are created, for example, three virtual network switches are needed to be created.

[0044] Step S30. According to the configuration requirements, the corresponding virtual computers are network-connected by using the virtual network switch to establish a virtual network, and the virtual network is connected with a physical network.

[0045] Step S40. In the virtual network, the software of the simulation machine system is functionally verified and performance tested, and according to the function verification result and the performance test result, the created virtual network switch and the virtual computer are optimized.

[0046] In this step, the simulation machine system running performance is optimized from multiple aspects, such as physical hardware, virtual machine system, application resource configuration and application task scheduling, etc., and high-performance computing in a virtualization environment is realized.

[0047] In this embodiment, hardware resources of one physical server are abstracted into multiple virtual computers by using a computing virtualization technology, and a virtual network switch is virtually created in the physical server by using a network virtualization technology, and network connection between the virtual computers and between the virtual computers and external physical computers is implemented. Therefore, a hardware and network environment for running a suite of simulation computer systems can be created by using only one physical server, so that deployment, running and testing of simulation computer software can be implemented. Compared with a simulation computer testing environment which is built by using more than ten computers in a traditional way, the number of devices required for installing a testing platform is greatly saved, installation space is saved, running cost is saved, and installation and maintenance efficiency is improved.

[0048] Further, in an optional embodiment, the configuration requirement includes a resource configuration requirement, and the resource configuration requirement includes a computing requirement, a memory requirement, a storage requirement and a network interface requirement. Moreover, step S20 further includes: creating a virtual operating station, a process model virtual server and a control logic virtual server with corresponding specifications respectively according to the computing requirement, the memory requirement, the storage requirement and the network interface requirement of the operating station, the process model server and the control logic server respectively. In this embodiment, for each virtual computer, resource can be reasonably allocated according to the requirements of computing, memory, storage and network resources required by the running software, so that reasonable use of hardware resources of the physical server is ensured.

[0049] Further, in step S20, when the virtual operating station is created, the synchronization of the system time of the virtual operating station and the system time of the physical server is cancelled according to the first setting information of the user. It should be noted that since the simulation time in the application software of the virtual computer will be automatically modified by the system time of the physical server, for the virtual operating station, the default setting of the synchronization of the system time of the virtual computer and the system time of the host system needs to be cancelled.

[0050] Further, in step S20, when the control logic virtual server is created, the corresponding USB port of the physical server is mapped into the control logic virtual server according to the second setting information of the user. It should be noted that for application software with copyright protection, for example, the application software in the control logic virtual server needs to be inserted into a USB physical dongle when running, so when the control logic virtual server is created, the USB port of the physical server needs to be mapped into the virtual computer (control logic virtual server), so as to realize access to the physical dongle in the virtual machine.

[0051] Further, in an optional embodiment, in step S20, a plurality of virtual computers of different specifications are created by using a lightweight virtualization technology, so that the minimum occupation of operating resources by operating systems in the virtual computers is achieved. In this embodiment, more hardware resources can be released by using the lightweight virtualization technology of server virtualization, so as to meet the requirements of more virtual machines. In addition, the scheduling scheme of the application software is also optimized, so as to reduce the computing resource conflicts and system idle waiting time, and improve the real-time performance of the application software.

[0052] Further, in an optional embodiment, the configuration requirements include network configuration requirements. Moreover, step S30 includes: after the operating system and the simulation machine software are installed in each virtual computer, the IP address of each virtual computer is configured according to the network configuration requirements.

[0053] Further, in an optional embodiment, before step S10, it further includes: according to the third setting information of the user, the power supply configuration attribute of the physical server is adjusted to the highest output performance. In this embodiment, by configuring the highest output performance of the physical server, the highest computing performance of the physical server is ensured to be fully exerted, so as to meet the high-performance computing requirements of the application software.

The operating environment construction system of this embodiment includes a receiving module 10, a creating module 20, a network connection module 30 and an optimization module 40. The receiving module 10 is used to receive the configuration requirements of the simulation machine system input by the user. The creating module 20 is used to create at least one virtual network switch and a plurality of virtual computers of different specifications by using the computing virtualization technology according to the configuration requirements. The virtual computers include a virtual operating station, a process model virtual server and a control logic virtual server. The network connection module 30 is used to connect the corresponding virtual computers by using the virtual network switch according to the configuration requirements to establish a virtual network, and connect the virtual network with the physical network. The optimization module 40 is used to perform function verification and performance testing on the software of the simulation machine system in the virtual network, and optimize the created virtual network switch and the virtual computers according to the function verification results and the performance testing results.

[0055] Further, the creating module 20 is further used to, when the virtual operating station is created, cancel the synchronization of the system time of the virtual operating station with the system time of the physical server according to the first setting information of the user; and when the control logic virtual server is created, map the corresponding USB port of the physical server to the control logic virtual server according to the second setting information of the user.

[0056] Further, the test running environment construction system of the simulation machine system of the present application further comprises an attribute setting module for adjusting the power supply configuration attribute of the physical server to the highest output performance according to the third setting information of the user.
