[0027] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0028] The following description, with reference to the accompanying drawings, outlines a method, apparatus, data generator, storage medium, and product for simulating data transmission according to embodiments of this application. Addressing the problems mentioned in the background section, this application provides a method for simulating data transmission. In this method, by inputting the server's connection address, target channel, the start and end ranges of the vehicle identifier, and the message to be sent into the data generator's interface, a large amount of simulated data can be generated. The operation is simple and convenient. Using a large volume of simulated data allows for better verification of the server's computing power, thereby effectively improving the overall performance of the vehicle networking system.

[0029] Specifically, Figure 1 This is a flowchart illustrating a simulated data transmission method provided in an embodiment of this application.

[0030] like Figure 1 As shown, the simulated data transmission method includes the following steps:

[0031] In step S101, a tool interface for creating a data generator is created.

[0032] The embodiments of this application can use the Java Swing framework to design the interface of a data generator utility, such as... Figure 2 As shown, there is a server connection address, vehicle identifier (vin) start number, number of threads, number of requests to be sent for each vin, target channel (topic), and message input box.

[0033] It should be noted that, in this embodiment of the application, a large number of regular VINs can be pre-inserted into the business database. Starting from TEST0000000000001, 10,000 data entries can be incremented for backup. For example, in this embodiment of the application, each subsequent VIN number can be incremented by 1 based on the previous one, until "TEST0000010000000", thereby forming a large number of regular VINs. Such an operation helps to simulate a large-scale real-world data environment and facilitates subsequent computational performance verification.

[0034] In step S102, the connection address of the server, the target channel, the start and end ranges of the vehicle identifiers and the message to be sent are entered in the tool interface. The target number of vehicle identifiers are generated according to the start and end ranges. Each vehicle identifier and the current time are filled into the message to be sent to generate simulated data.

[0035] The simulated data can be battery signal data, including one or more of the following: vehicle identification, battery level, voltage, charging current, discharging current, and battery health status. The simulated data is used to verify the computing performance of the server.

[0036] like Figure 2As shown in the embodiment of this application, the user can input the Kafka connection address, the start and end ranges of the VIN, the number of threads, the number of requests to be sent per VIN, the target channel topic, and the message content to be sent on the tool interface. By clicking the submit button, the getText() method of JTextField is used to obtain the Kafka connection address, VIN start number, number of threads, number of requests per VIN, the topic content to be sent, and the message, respectively. The operation is simple and convenient.

[0037] Furthermore, in this embodiment, a continuous or specified number of VIN sequences can be automatically generated based on the start and end ranges of the VINs input by the user; by encoding the vehicle identifier as a string and identifying the actual vehicle identifier and actual time in the message to be sent; by replacing the actual vehicle identifier and actual time in the message to be sent with the encoded vehicle identifier and current time, simulated data is obtained. The simulated data is in the correct format and conforms to the data standards of the vehicle networking system. Thus, by generating a large amount of valid data and sending it to the Kafka server, it is used for subsequent verification of computing capabilities, thereby improving the overall performance of the vehicle networking system.

[0038] In step S103, simulated data is sent to the target channel sequentially according to the server's connection address.

[0039] In one embodiment of this application, simulated data is sequentially sent to the target channel according to the connection address of the server, including: a virtual button for sending simulated data is set on the tool interface; when the virtual button is triggered, a corresponding number of worker threads are created according to the set number of concurrent threads, wherein each worker thread connects to the server according to the connection address, and after the connection is successful, it repeatedly executes the operation of obtaining simulated data and sending it to the target channel until the preset number of sending times is met, and then the sending stops.

[0040] The preset number of sends can be the number of requests that need to be sent for each vin, or it can be set according to the actual situation without specific limitation.

[0041] It is understood that this embodiment of the application can create a thread group, with each thread creating a KafkaProducer object, configuring ByteArraySerializer for serialization, and establishing a secure and reliable network connection based on the provided server address. If the connection to the server fails, a failure message is generated and displayed on the tool interface. If the connection to the server succeeds, this embodiment of the application can encode each VIN as a string, obtain the current time, replace the VIN and time in the message, and call the send() method to send simulated data to the specified target channel in a loop. In actual execution, this embodiment of the application can send simulated data in byte array format to ensure the performance and reliability of data transmission.

[0042] The following is combined Figure 3 The simulated data transmission method of this application embodiment will be described in detail, including the following steps:

[0043] (1) Insert a large number of regular vins into the business database, starting from TEST0000000000001 and incrementing by 10,000 records for later use.

[0044] (2) Use the java.swing framework to design the interface of the data generator tool and input the relevant data.

[0045] (3) When the submit button is clicked, the getText() method of JTextField is used to obtain the Kafka connection address, VIN starting number, number of threads, number of requests per VIN, topic content and message sent. A thread group is created, and each thread creates a kafkaProducer object, configures ByteArraySerializer, and connects to the Kafka server.

[0046] (4) Determine if the connection is successful. If successful, execute (5) operation. If unsuccessful, print an error message.

[0047] (5) After encoding the vin as a string, get the current time, replace the vin and time in the message, and call the send() method to send messages to the specified topic in a loop.

[0048] According to the simulated data transmission method proposed in the embodiments of this application, a large amount of simulated data can be generated by inputting the server's connection address, target channel, vehicle identification start and end ranges, and the message to be sent on the tool interface of the data generator. The operation is simple and convenient. A large amount of simulated data can better verify the server's computing power and effectively improve the overall performance of the vehicle networking system.

[0053] In one embodiment of this application, the sending module 300 is further configured to have a virtual button for sending simulated data on the tool interface; when the virtual button is triggered, a corresponding number of worker threads are created according to the set number of concurrent threads, wherein each worker thread connects to the server according to the connection address, and after the connection is successful, it repeatedly executes the operation of obtaining simulated data and sending it to the target channel until the preset number of sending times is met, and then the sending stops.

[0054] In one embodiment of this application, the generation module 200 is further configured to: encode the vehicle identifier as a string, and identify the actual vehicle identifier and actual time in the message to be sent; replace the actual vehicle identifier and actual time in the message with the encoded vehicle identifier and current time to obtain simulated data.
