The execution sequence of the method steps in the embodiments of the present invention may be performed according to the sequence described in the specific embodiments, or the execution sequence of each step may be adjusted according to actual needs on the premise of solving the technical problem, which is not listed here.

The large concurrent pressure test of remote vehicle control is a software test method and is focused on evaluating the performance and reliability of a vehicle remote control system in the face of a large number of concurrent requests and high concurrent user operations. The test measures response time, resource utilization, stability, and possible performance bottlenecks of the system under extreme loads by simulating multiple users to simultaneously perform remote vehicle control operations, such as unlocking, locking, activating air conditioning, and the like. The purpose is to ensure that a vehicle remote control system can effectively cope with high concurrency situations in actual use and provide smooth and stable service. This helps identify and solve potential problems to ensure that the system remains operating efficiently when large-scale users are simultaneously using it.

In the large concurrent pressure test of remote vehicle control, the T-BOX simulation example plays a key role, and the performance and stability of the vehicle remote control system under the conditions of high load and simultaneous access of multiple users are comprehensively evaluated by simulating the identity authentication of the vehicle or the user, generating an identity token and simulating the concurrent user operation. The T-BOX simulation example is combined with the test scene, so that the efficiency of the system in key aspects such as identity authentication, access control and response time in large-scale user operation is verified, and comprehensive evaluation and optimization basis is provided for the overall performance of the system. The comprehensive testing method is helpful for finding and solving the possible performance bottleneck in the large concurrency environment, and ensures that the remote vehicle control system can operate efficiently and reliably in practical application.

The invention is described in further detail below with reference to fig. 1-4.

Referring to fig. 1, a T-BOX simulation method provided by an embodiment of the present invention includes:

s1, generating a preset number of T-BOX simulation examples;

s2, when each T-BOX simulation instance is generated, establishing a message channel between the T-BOX simulation instance and middleware for testing;

S3, based on the message channel, processing the message of the T-BOX simulation instance and the middleware.

Specifically, first, a preset number of T-BOX simulation instances are generated by S1, which involves setting parameters such as the number of T-BOX instances and initial configuration. Then, at the S2 stage, when each T-BOX simulation instance is generated, through a specific initialization process, an effective message channel is ensured to be established between the T-BOX simulation instance and the middleware for testing, including identity authentication, key exchange or other security mechanisms of the T-BOX simulation instance, so as to ensure the security and reliability of communication. Finally, in S3, based on the message channel, a message between the T-BOX simulation instance and the middleware is processed. This process includes receiving and parsing messages from the middleware while generating and sending simulated identity and access management messages to the middleware. Overall, the T-BOX simulation method can effectively simulate the communication process between multiple T-BOX instances and middleware, and provides a reliable means for performance testing of identity and access management systems.

Further, as an embodiment of the present invention, the generating a preset number of T-BOX simulation instances includes: acquiring configuration parameters of the T-BOX simulation instance, wherein the configuration parameters at least comprise the quantity of the T-BOX to be generated; and generating T-BOX simulation examples corresponding to the number of the T-BOXs according to a preset command function based on the configuration parameters.

Specifically, first, the step of obtaining configuration parameters of the T-BOX simulation instance is performed, including obtaining relevant parameters from a predetermined configuration source, including at least the number of T-boxes that need to be generated. Then, on the basis of acquiring the configuration parameters, a step of generating a T-BOX simulation instance according to a preset command function is performed. This involves generating a corresponding number of T-BOX simulation instances one by one, based on the number of T-boxes specified in the configuration parameters, using a predefined command function. The process of generating the T-BOX simulation instance may include initializing identity information of the T-BOX instance, configuring security policies, assigning unique identifiers, and the like. Overall, this embodiment effectively generates the required number of T-BOX simulation instances by explicitly defining configuration parameters and preset command functions, providing a controllable and repeatable environment for subsequent identity and access management system testing.

Further, as an embodiment of the present invention, the configuration parameters further include at least one of a thread number, encryption and decryption requirements, a start bit, an IP address of the message middleware, and a preset step sleep time.

Specifically, the configuration parameters cover a plurality of key aspects, including at least one of thread number, encryption and decryption requirements, start bit, IP address of message middleware and preset step sleep time. The thread number designates the number of concurrent threads started in the test process, the encryption and decryption requirements indicate whether encryption and decryption operations are needed to be carried out on the transmitted message, the initial value of an identifier when the T-BOX simulation instance is generated is set as a start bit, and the IP address of the message middleware is used for establishing communication connection with the middleware. The preset step sleep time refers to a pause time between execution of preset steps, and includes at least one designated time period. The combined effect of these configuration parameters is to provide flexibility and customization for the generation and testing of T-BOX simulation instances to meet specific test scenarios and requirements.

Further, as an embodiment of the present invention, the presetting step includes the T-BOX simulation instance receiving a vehicle control command.

Specifically, during the sleep time between preset steps, the T-BOX simulation instance is designed to be able to receive and process vehicle control instructions from the test scene. Such a design allows for simulating the timely response of T-BOX simulation instances to vehicle remote control commands in an actual scenario during testing in order to comprehensively evaluate the performance and reliability of the system in the concurrent scenario of vehicle control commands. By introducing this step during sleep, the behavior of the T-BOX system in actual use can be more realistically simulated and more accurate data can be provided for comprehensive assessment of system performance.

Further, as an implementation mode of the present invention, the preset step further includes the T-BOX simulation instance successfully processing the received vehicle control instruction and reporting the executed vehicle control instruction to the T-BOX simulation instance.

Specifically, in a specific test scenario, the preset step of the T-BOX simulation instance includes simulating a vehicle remote control process. First, the T-BOX simulation instance successfully receives a simulated vehicle control command, such as an unlock, lock, etc. Then, the T-BOX simulation instance is designed to successfully process the received instructions, simulate the response flow of the actual system to the operation of the vehicle, and ensure the accuracy and reliability of the execution process.

Meanwhile, in the preset step, the T-BOX simulation example also simulates the process of reporting the executed vehicle control instruction. This means that the T-BOX simulation instance reports executed instruction information, including execution results, state changes, and the like, to the system after successfully executing the vehicle control instruction. The design is helpful for verifying the recording and tracking functions of the system for executing the operation on the T-BOX instance, and ensuring that the system can accurately acquire and process the operation information of the T-BOX simulation instance in practical application.

Through the series of specific preset steps, a tester can comprehensively evaluate the overall performance of the T-BOX system in a vehicle remote control scene, and the overall performance comprises the aspects of receiving instructions, processing the instructions, executing operations, reporting execution results and the like, so that detailed test data are provided for the reliability and stability of the system.

Illustratively, a specified number of T-BOX simulation instances are generated at a time, formed in accordance with the following command function: java-jar T-BOX. Jar < T-BOX number > < thread number > < whether encryption/decryption is required > < start bit > < IP address of emq_token > < sleep time after subscribing to 5/7 > < sleep time before issuing 5/5 > < sleep time before issuing 5/9 >, wherein:

the T-BOX number represents a total number of T-BOX simulation instances specified to be initialized;

the thread number represents the number of concurrent threads appointed to be started, and is suggested to be a multiple of the CPU core number so as to fully utilize system resources;

whether encryption and decryption are needed indicates whether the MQTT message is specified to be encrypted and decrypted, and the digital representation is used (0: not encrypting and decrypting |1: encrypting and decrypting using international algorithm |2: encrypting and decrypting using national encryption algorithm).

The start bit represents the start bit of the clientid suffix for the T-BOX simulation instance, and the following clientid will accumulate 1 one by one.

IP address of emq_token: the IP address of the EMQ message middleware is specified.

Sleep time after subscribing to 5/7 represents the sleep time in milliseconds after the T-BOX simulation instance subscribes to message 5/7.

The sleep time before issue of 5/5 represents the sleep time in milliseconds before the T-BOX simulation instance issues message 5/5.

The sleep time before 5/9 is published represents the sleep time in milliseconds before the T-BOX simulation instance publishes message 5/9.

Further, the above:

subscription 5/7 indicates that the T-BOX simulation instance received a vehicle control instruction;

issuing 5/8 to indicate that the T-BOX simulation instance successfully processes the received vehicle control instruction;

And issuing a 5/5T-BOX simulation example to report the executed vehicle control instruction.

Further, the vehicle control command includes, but is not limited to, unlocking, locking, turning on the air conditioner, turning off the air conditioner, increasing the upper pressure, decreasing the lower pressure, etc.

Further, as an embodiment of the present invention, the message channel is created when the T-BOX simulation instance is created.

Specifically, the T-BOX simulation instance establishes a communication channel with the message middleware in an initialization stage. This channel is a bi-directional interaction path that enables the T-BOX simulation instance to communicate information with the message middleware in real time. By creating the message channel while the T-BOX simulation instance is being created, it is ensured that the T-BOX instance has the capability of communicating with the middleware immediately after being started, so that subscription, publishing and other operations related to middleware interaction can be performed while participating in the message passing process of the whole system. The design of the real-time establishment channel is beneficial to ensuring that the T-BOX simulation instance can timely respond to the message demand of the system in the running process, and realizing the accuracy and the instantaneity of the simulation test.

Further, referring to fig. 2, step S3, as an embodiment of the present invention, processes, based on the message channel, the message of the T-BOX simulation instance and the middleware, including:

S31, sending the message of the T-BOX simulation example to the middleware through the message to subscribe to a terminal to be tested;

S32, after the test terminal subscribes to the message, replying a corresponding return message to the middleware so as to subscribe to the T-BOX simulation instance;

S33, after the T-BOX simulation instance subscribes to the return message, the return message is processed.

Specifically, first, in S31 stage, a message of the T-BOX simulation instance is sent to the middleware through the message channel, so as to wait for the subscription of the test terminal. This involves passing messages generated by the T-BOX simulation instance through the channel to the message middleware so that subsequent test terminals can subscribe to these messages.

Then, in S32, once the test terminal subscribes to the message, it replies to the middleware with a corresponding return message to wait for the T-BOX simulation instance subscription. This phase simulates the response behavior of the test terminal to the T-BOX simulation instance message, ensuring that the message is properly delivered and responded to in the system.

Finally, in S33, after the T-BOX simulation instance subscribes to the return message, it processes the subscribed return message. This may include parsing the message content, performing corresponding operations, and performing analog control of the system. The whole process realizes the bidirectional transmission and processing of the messages between the T-BOX simulation instance and the middleware through the synergistic effect of the message channels, and provides a controllable and observable communication environment for the test scene.

The step S3 is used for effectively processing the message between the T-BOX simulation instance and the middleware and ensuring the bidirectional transmission and the processing flow of the message in the system. First, in S31, a message generated by the T-BOX simulation instance is sent to the middleware through a message channel, so that a terminal subscription to be tested is to be tested. Then, in S32, after subscribing to the message, the test terminal replies a corresponding return message to the middleware, so as to simulate the response of the test terminal to the T-BOX simulation instance message. Finally, in S33, the T-BOX simulation instance subscribes to the return message and processes it, possibly involving operations such as message parsing, simulation control, etc. The whole flow simulates the interaction process of messages between the T-BOX instance and the test terminal in the actual system, and provides a controllable and observable test environment to verify the performance and reliability of the T-BOX system in terms of message transmission and processing.

Further, as an embodiment of the present invention, the first message after the message channel is created is a login message, and the return message is a login confirmation message.

Specifically, once a message channel is created, the system specifies an initial message interaction flow. In this flow, the first message sent by the T-BOX simulation instance is a login message, which indicates that the T-BOX simulation instance performs authentication and establishes a connection in the system. And then, after receiving the login message, the test terminal replies a corresponding return message, namely a login confirmation message, so as to confirm the validity of the T-BOX simulation instance. This initial message interaction process simulates the login and authentication operations of the devices in the actual system, ensuring that the T-BOX simulation instance can successfully access the system at the beginning of the test, and that the system can properly respond and confirm the connection. The design is helpful for establishing a stable and reliable communication channel in a test environment, and provides a reliable basis for subsequent test scenes.

Illustratively, as shown in the dashed BOX of FIG. 3, I1-S1 is a message issued to the EMQ for the 1 st T-BOX simulation instance, where after the T-BOX simulation instance is initialized, the first message issued is 2/1 for aid and mid, i.e.: aid 2, mid:1.

I1-S2 is the message to which the 1 st T-BOX simulation instance subscribes from EMQ, and the aid and mid of the received message should be 2/2, namely: aid 2, mid 2.

I2-S1 is a message issued to the EMQ by the 2 nd T-BOX simulation instance, and after the T-BOX simulation instance is initialized and generated, the aid and mid of the first issued message are 2/1, namely: aid 2, mid:1.

I1-S2 is the message to which the 2 nd T-BOX simulation instance subscribes from EMQ, and the aid and mid of the received message should be 2/2, namely: aid 2, mid 2.

And so on until:

In-S1 is a message issued to the EMQ by the nth T-BOX simulation instance, after the initialization and generation of the T-BOX simulation instance, the aid and mid of the first message issued are 2/1, namely: aid 2, mid:1.

In-S2 is the message to which the nth T-BOX simulation instance subscribes from EMQ, and the aid and mid of the received message should be 2/2, namely: aid 2, mid 2.

In summary, after all the T-BOX simulation instances are started, 2/1 is sent out, then the subscription to 2/2 is waited, and only after the subscription to 2/2 is completed, the following steps are continued, wherein the following steps comprise:

subscription 5/7, subscription to vehicle control instructions;

Issuing 5/8, and issuing ACK (acknowledgement) to the cloud;

and 5/5, reporting the event, wherein the reported content is a vehicle control instruction.

The embodiment of the invention also discloses a system for simulating the T-BOX.

Referring to fig. 4, a T-BOX simulation system includes a simulation instance creation module 1, a message channel creation module 2, and a message processing module 3.

An embodiment of the simulation instance creation module 1 includes obtaining configuration parameters of T-BOX simulation instances, including at least the number of T-boxes to be generated, and generating a corresponding number of T-BOX simulation instances using a preset command function based on the configuration parameters. The module is used for generating a specified number of T-BOX simulation examples at one time through preset configuration parameters and command functions, simulating the existence of a plurality of devices in the T-BOX system and providing a test environment for subsequent large-scale concurrent tests. This ensures that the system is able to efficiently handle concurrent operation of multiple T-BOX simulation instances in a test, evaluating the performance and stability of the T-BOX system under large scale loads.

An embodiment of the message channel creation module 2 includes immediately creating a message channel with the middleware for testing at the time of each T-BOX simulation instance generation, i.e., simulation instance creation phase. This channel is a bi-directional communication path that enables real-time message interaction between the T-BOX simulation instance and the middleware. Typically, this involves the steps of connection configuration, authentication and handshaking between the T-BOX simulation instance and the middleware, ensuring proper establishment of the channel. The function of this module is to ensure that the T-BOX simulation instance is immediately capable of communicating with the middleware upon initialization generation. By establishing a message channel while the T-BOX simulation instance is generated, the system can immediately subscribe and publish the message after the T-BOX instance is started, and simulate real-time communication of the T-BOX instance in an actual system. This helps the tester to precisely control the behavior of the T-BOX instance in a simulated environment, evaluating the responsiveness and accuracy of the system to instant messaging.

The embodiment of the message processing module 3 relates to processing a message between a T-BOX simulation instance and middleware to ensure that the message passing and processing flow inside the system is operating normally. In practice, the module may include key steps such as messaging, subscription, response, and processing. First, a message generated by the T-BOX simulation instance is sent to the middleware through an established message channel to wait for subscription of the test terminal. And after the test terminal subscribes to the message, replying a corresponding return message to the middleware, and simulating the response of the test terminal to the T-BOX simulation instance message. Finally, after the T-BOX simulation instance subscribes to the return message, the return message is processed, which may include operations such as message parsing and simulation control. The module is used for simulating the real-time transmission and processing process of the messages in the T-BOX system, and providing a controllable test environment for evaluating the system performance and reliability. By observing the transmission of the message and the processing of the message by the T-BOX simulation example in real time, the tester can comprehensively evaluate the performance of the system under the large-scale concurrent load.

The synergistic effect of the three modules enables the T-BOX simulation system to efficiently conduct remote controlled large concurrent pressure testing in a simulation environment. The multiple instance generation module provides a controllable simulation of the number of devices, the message channel setup module ensures real-time communication between instances, and the message processing module simulates the full life cycle of messages in the T-BOX system. Overall, they together construct a controllable, observable test environment that provides a comprehensive assessment of T-BOX system performance, stability and reliability.

The embodiment of the invention also discloses a T-BOX simulator. The simulator at least comprises the T-BOX simulation system in the embodiment.

Specifically, an embodiment of the present invention discloses a T-BOX simulator, which at least includes the above-mentioned T-BOX simulation system. The T-BOX simulation system comprises a simulation instance creation module, a message channel creation module and a message processing module, and forms a complete T-BOX simulation environment together. The T-BOX simulator provides a controllable and observable platform for large-scale concurrent pressure test of a remote vehicle control system by creating a simulation instance, establishing a message channel with a middleware and simulating a message processing process. The design of the T-BOX simulator helps to evaluate the performance of the T-BOX system in real scenes and provides a reference for optimizing and improving the system.

For concurrent pressure testing of platform interfaces, it is not sufficient to invoke the interface only, without regard to downstream testing. And the whole link closed loop is also concerned, and the performance index is monitored on each node, so that the real performance of the target to be controlled can be accurately controlled. The T-BOX simulator is used for simulating T-BOX firmware of a vehicle end, and corresponding messages are published and subscribed to sequentially. The command sent by the remote car control interface of the platform after being called can be received and replied by the simulated car end T-BOX, so that the whole remote car control link is closed.

The test staff generally adopts direct calling interface and checking the replied message to carry out interface test, but in the cloud platform, after the target interface is usually requested, the data in the request message is directly transmitted to the service at the downstream of the link, the test staff can easily ignore or don' T care the execution condition of the downstream link, and directly takes the successful message returned by the interface as the basis, so that the method is inaccurate, even erroneous, and the reply of the simulated vehicle end T-BOX is taken as the remote vehicle control execution success standard.

If the emulated vehicle end T-BOX fails to subscribe to the message from the message middleware or replies to the message after subscribing to the message, i.e., issues a new message to the message middleware for the remote vehicle control service to subscribe to, but the remote vehicle control service fails to subscribe to, then this indicates that there may be other components in the remote control link that are malfunctioning, thus helping to locate the problem from the side and helping to eliminate the problem.
