The present invention reduces useless vehicle data collection item content and saves bandwidth resources.

Description

Technical Field

[0001] The invention relates to a data acquisition method, in particular to a remote automobile bus flexible data acquisition method. Background Art

[0002] Vehicle bus data collection refers to obtaining data from various electronic control units and sensors in vehicles. These data can be used to monitor, analyze and control various systems and functions of the vehicle. With the development of Internet of Vehicles technology, the vehicle network structure is becoming more and more complex, and the body information that can be collected is diversified. Under the traditional technical background, the data collection terminal collects all data through the data collection terminal and reports all the vehicle bus data to the cloud platform.

[0003] In the case of full data collection, the data requirements for remote monitoring and fault diagnosis of vehicles in the era of intelligent networking are met. However, the amount of data generated in the process of full data collection is too large and precious bandwidth resources are wasted. Therefore, a flexible data collection method based on actual application scenarios is needed. Summary of the invention

[0004] The purpose of the present invention is to provide a flexible data collection method for a remote vehicle bus, and to provide a flexible remote data collection and analysis solution for different application scenarios.

[0005] The present invention is achieved by the following technical solutions:

[0006] A remote vehicle bus flexible data acquisition method includes a data acquisition terminal and a vehicle bus, and the specific steps are as follows:

[0007] S1. The vehicle is powered on, and the data collection terminal starts with the vehicle;

[0008] S2. After the data collection terminal is started, the flexible data collection item configuration under different scenarios is loaded from the device database. The configuration content includes all the data identifications that need to be collected, the collection frequency, and whether to collect;

[0009] S3, handshake with the cloud platform, and after the handshake is successful, exchange data with the cloud platform;

[0010] S4, the platform operator flexibly configures the data item content according to different application scenarios to form instructions, and sends them to the data collection terminal. When the data collection terminal receives the flexible data configuration item instruction sent by the cloud platform, it proceeds to the next step S5. If it does not receive the instruction, it proceeds to the next step S7;

[0011] S5. After receiving the flexible data configuration item instruction, obtain the collection data identifier, collection frequency and all collection instruction contents of the flexible data collection item configuration from the instruction, and proceed to the next step S6;

[0012] S6. Execute the storage of the content of the flexible data configuration item, store the data in the device database, and wait for the next power-on to enter step S2 again to take effect;

[0013] S7, collect vehicle data according to the configuration of the flexible data collection item loaded in S2, filter out the unloaded vehicle data, and send the designated collected vehicle data to the next step S8 for data combination;

[0014] S8, after receiving the designated collected vehicle data, the data collection terminal splices the same data identification data, then combines multiple data into a whole package of data, and proceeds to the next step S9 to report the data;

[0015] S9. The data collection terminal reports the entire data package to the cloud platform, and then continues to wait for the entire data package to be transmitted until the vehicle is powered off and stops reporting.

[0016] Compared with the traditional full-volume vehicle data collection method, the present invention can collect data on demand according to the actual application scenario requirements, reduce useless automobile data collection items, save bandwidth resources, and also provide data support for remote analysis of vehicle performance and operating status, and assist in analyzing and solving various vehicle fault problems.
