[0021] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0022] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise", "include", etc. used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0023] All terms (including technical and scientific terms) used herein have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification, and should not be interpreted in an idealized or overly rigid manner.

[0024] When using expressions such as "at least one of A, B, and C, etc.", they should generally be interpreted according to the meaning of the expression commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0025] First, the technical terms involved in this disclosure are explained as follows:

[0026] MQTT client: The full name is MQTT message queue client, which is a mobile node in the MQTT network, used to send and receive messages. It establishes a connection with the MQTT server (Broker) to realize functions such as message publishing (Publish), subscription (Subscribe), and unsubscription (Unsubscribe). MQTT client can run on various devices, such as sensors, embedded devices, servers, mobile devices, etc., as long as these devices support the MQTT protocol and can achieve network connection.

[0027] Kafka queue: The full name is Apache Kafka, which is a distributed message queue (MQ, Message Queue) based on the publish / subscribe mode. Kafka is mainly used to solve the message delivery problem in large-scale data processing. The producer sends the message to the Kafka server, and can choose to send it to a specified partition or let Kafka automatically select the partition according to the load balancing strategy. Kafka organizes and manages messages in the form of topics. Each topic contains multiple partitions. Each partition can be understood as an independent log file. The messages in the partition are arranged in order and have a unique offset. The consumer subscribes to the topic from the Kafka broker and obtains the assigned partition, and then pulls messages from the partition for consumption. Kafka supports multiple consumer groups. Consumers in each consumer group share messages from a topic, but do not consume messages repeatedly.

[0028] MinIO Client: mc for short, is the client tool of the MinIO server. It is a feature-rich command line tool designed to interact with the MinIO object storage service and its compatible S3 storage service.

[0029] Since the vehicle test bench equipment data exists in the host computer data file, it is necessary to manually upload the data to the cloud for data utilization, which increases the workload and is not conducive to the intelligent development of the enterprise. Figure 1 The flowchart of the data collection method of the vehicle test bench applied to the test bench host computer according to the embodiment of the present disclosure is schematically shown. Figure 1 As shown, an embodiment of the present disclosure provides a data collection method for a whole vehicle test bench, and the method is applied to a test bench host computer, including: connecting a device access gateway for communication with the device access gateway; the device access gateway is used to manage the test bench host computer; in response to receiving a collection task sent by the device access gateway, automatically uploading the test data to a cloud server according to the collection task; the collection task includes at least one of a test bench number, a test name, a file type, a file path, and a collection method.

[0030] In this embodiment, a collection client is installed on the host computer of the test bench equipment; the client specifically adopts the MQTT client application, and adopts the general protocol in the field of Internet of Things to facilitate better expansion and compatibility. The collection client is responsible for communicating with the MQTT server in the cloud. After the collection client application is started, it automatically connects to the device access gateway in the cloud. After the login verification is passed, the device access gateway pushes the device online status to the message queue. The collection client receives the collection task and scans the specified directory; the collection client starts to upload the test data to the cloud server. After the upload is completed, the result status is reported to the device access gateway, and then reported to the cloud. Through standardized connection and communication methods, it is ensured that the host computer of the test bench can quickly respond to the instructions of the device access gateway to achieve efficient data interaction.

[0031] In this embodiment, the collection mode can be set to manual or automatic. In the automatic mode, a collection task is issued at regular intervals, thereby realizing automatic collection of test data.

[0032] Through the embodiments of the present disclosure, a collection client is installed on the host computer to communicate with the cloud device access gateway. When the collection client receives the collection task sent by the device gateway, it scans the host computer file directory and reports the file information (including metafile information, test items, professions, etc.). The collection client starts uploading the test file to the file server. After the upload is completed, the result status is reported, and the access gateway updates the file upload status of the current test task. The method is simple in logic and easy to implement. It can flexibly respond to the expansion of communication protocols to save enterprise costs, and can monitor the device status in real time. Automatically uploading test data according to the collection task reduces manual intervention and improves the efficiency and accuracy of data processing.

When the collection client connects to the device access gateway, it performs identity authentication, i.e. logs in, and reports its identity information to the device access gateway. The device access gateway verifies the device information and publishes a device online message after the authentication is passed. Other cloud services can receive device online notifications by subscribing to messages. The collection client maintains the connection with the device access gateway by sending heartbeats at regular intervals. When the device access gateway does not receive the heartbeat of the collection client for a certain period of time t, it considers that the client is offline and publishes a device offline message. The service that subscribes to the message topic will receive the device offline notification.

[0036] Through the embodiments of the present disclosure, the online state is maintained through heartbeat messages to ensure that the connection between the test bench host computer and the device access gateway is stable and reliable; the connection can only be established after the device login request is verified, which enhances the security of the system and prevents unauthorized access.
