However, those skilled in the art will understand that many technical details are presented in the various embodiments of the present invention to facilitate a better understanding of this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments. The division of the various embodiments below is for ease of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined with and referenced by each other without contradiction.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a system, product, or device that includes a series of components or units is not limited to the listed components or units, but may optionally include unlisted components or units, or may optionally include other components or units inherent to such products or devices. In the description of this application, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0019] Regarding the current cloud simulation based on hardware-in-the-loop simulation, the inventors discovered at least the following drawbacks when implementing this invention:

[0020] Most embedded software lacks a dynamic simulation environment and often relies on manual simulation. This makes it impossible to verify the system's dynamic real-time response, performance under various extreme conditions, and fault tolerance. Some performance characteristics can only be verified through field tests. All of these problems greatly affect the development cycle and significantly increase development costs.

[0021] There is no general embedded software simulation platform, usually a certain simulation device is only for a certain software or several software, which cannot meet the needs of most embedded software simulation, and the universality is poor.

[0022] The simulation personnel can only take the measured part to the simulation system site for simulation, and the measured part cannot be simulated in a remote place, the simulation cost is high, and the simulation efficiency is low.

[0023] The simulation system is small in scale, and cannot realize distributed and parallel simulation at the system level.

[0024] Therefore, the cloud simulation technology is adopted, the simulation personnel can write simulation cases on the local client, and the simulation cases are remotely uploaded to the cloud simulation server. The cloud server can remotely configure the client simulation target machine according to the simulation cases, run the simulation code, and carry out real-time, closed-loop and non-intrusive black-box automatic simulation on the measured embedded software. All data in the simulation process and the simulation report can be saved in the database in the cloud. The client can monitor the simulation data, and the client computer can download the simulation results and the simulation report after the simulation is completed.

[0025] The first embodiment of the present application relates to a cloud simulation system, specifically as shown in Figure 1 The cloud simulation system includes a cloud simulation server and a cloud simulation client, wherein the cloud simulation server and the cloud simulation client are connected with the server through the Internet or a local area network, and adopt a B / S (Browser / Server) architecture. Compared with the traditional C / S (Custom / Server) architecture, the B / S architecture has strong distribution, is convenient to maintain, simple to develop, has strong sharing, and is low in overall cost.

[0026] The cloud simulation server includes a simulation server, a server simulation target machine and a database server, wherein the simulation server and the database server communicate with the server simulation target machine through TCP / IP, and the server simulation target machine is connected with the measured part through I / O and bus signals.

[0027] The cloud simulation client includes a client device and a client simulation target machine, wherein the client simulation target machine is connected with the measured part through I / O and bus signals, and the client device can be a computer, a mobile phone or a tablet computer.

[0028] As Figure 2As shown, the cloud simulation system further comprises a cloud service module and an automatic test management module, wherein the cloud service module is specifically used for user management, permission management, cloud communication management, and report uploading and downloading; and the automatic test management module is specifically used for test requirement management, test execution, database management, test development management, a graphical monitoring interface, test model establishment, a communication interface component, test result analysis, real-time simulation, a data dictionary, log management, automatic script generation, and automatic test report generation.

[0029] It is worth mentioning that in the cloud simulation system of the embodiment, multiple cloud simulation clients can simultaneously transmit data and instructions with the cloud simulation server through the network. The cloud simulation client has user and permission management functions. When the cloud simulation client performs simulation, the cloud simulation server assigns a user account and password to the simulation personnel of the cloud simulation client, so that the simulation personnel can log in by inputting the user name and password through a webpage of any computer connected to the Internet, write simulation test cases, and perform simulation. In addition, the simulation personnel can also download a client APP through the client device, and after logging in to the APP, they can write simulation test cases and perform simulation work.

[0030] In addition, the cloud simulation system of the embodiment has the following features:

[0031] High expansibility: multiple cloud simulation servers and cloud simulation clients can be expanded for system-level distributed parallel simulation. More I / O, bus interface channels, and greater computing power can be obtained by adding I / O board cards and simulation target machines, which have device-level expansion capability. Moreover, the measured object can simultaneously perform simulation tests of different test projects through multiple server simulation target machines and client simulation target machines.

[0032] Interconnection: the cloud simulation client and the cloud simulation server are connected through the Internet using the B / S architecture, and multiple cloud simulation clients can be used to remotely perform simulation test case and simulation configuration information writing and other work on the measured object in different places.

[0033] Versatility: different application models and test tasks can be developed to meet the testing of multiple models or multiple systems. For example, in addition to supporting the Matlab / Simulink model tool, the system also supports other model tools such as Demola, ANSYS, GT-Power, AMEsim, CarSim / TruckSim, etc. Multiple cloud simulation servers and cloud simulation clients can be expanded to realize joint simulation testing of multiple systems.

[0034] Real-time performance: the server simulation target machine and the client simulation target machine use Linux / Redhat real-time operating system to ensure real-time testing of the system.

[0035] The second aspect embodiment of the present application provides a cloud simulation method based on the cloud simulation system in the above embodiment, and the method comprises the following steps:

[0036] In step S1, the positions of the cloud simulation client and the measured object are determined.

[0042] If the measured object is in the cloud simulation server and the cloud simulation client is in a remote place, a simulation personnel compiles a simulation case of a test item of the measured object through a client device of the cloud simulation client, sends a simulation request and the simulation case to the cloud simulation server through a network, and the simulation request includes the test item of the measured object; when the simulation server obtains the simulation case, the simulation server downloads a simulation script of the simulation case to a server simulation target machine, and the server simulation target machine performs simulation testing on the measured object according to the test item of the measured object.

[0043] If both the cloud simulation client and the device under test (DUT) are located in different locations, the simulation personnel write simulation test cases for the DUT's test items using the client device of the cloud simulation client, and send the simulation request and the simulation test cases to the cloud simulation server via the network. The simulation request includes the test items of the DUT. When the simulation server obtains the simulation test cases, it downloads the simulation script of the simulation test cases to the client simulation target machine, and the client simulation machine performs simulation testing on the DUT according to the test items of the DUT.

[0044] In step S3 of this embodiment, the cloud simulation server and the cloud simulation client monitor the simulation test data, and the cloud simulation server stores the simulation test results after the simulation test is completed. Specifically:

[0045] During the simulation test, the simulation test data can be monitored on both the cloud simulation server and the cloud simulation client. After the simulation test is completed, the simulation server generates simulation results and simulation reports based on the simulation test data. The simulation test data, simulation results, and simulation reports are stored in the database server. The cloud simulation client can send a request to the cloud simulation server to obtain the simulation test results and / or simulation reports from the database server.
