Problems solved by technology

Due to the "multi-source heterogeneous" characteristics of the data generated by the Internet of Vehicles terminal (such as pictures, text, video, audio, etc.), general software tools are difficult to fully handle the extraction, management and processing of these data.
[0005] 2) Dirty data problem
[0006] 3) Data storage reliability issues
At this stage, the transmission speed of real-time data of the Internet of Vehicles is fast and the data volume is large, but there are still great defects in the real-time and reliability of the data storage process.

[0038] figure 1 It is a schematic composition diagram of the real-time data processing system of the Internet of Vehicles provided by the embodiment of the present invention. From figure 1 It can be seen from the figure that the system is mainly composed of modules of a real-time data monitoring layer 100 , a real-time data review layer 200 , a real-time data processing layer 300 , and a real-time data storage layer 400 . in:

[0039] The real-time data monitoring layer 100, the modules at this level are mainly responsible for real-time monitoring of the data source of the Internet of Vehicles terminal, to realize the real-time monitoring of the real-time update status of the terminal data, so as to provide "real-time" data for the real-time data review layer 200 . Wherein, in order to achieve an accurate and efficient monitoring effect, the present invention preferably adopts a monitoring strategy based on a combination of time difference and fixed frequency to dynamically ...

[0052] In order to illustrate the technical solution of the present invention more clearly, the working method of the above-mentioned system will be briefly introduced below in conjunction with the accompanying drawings. As mentioned above, when the vehicle is running, due to the complex operating environment of the vehicle, abnormal data often occurs. These abnormal data include data containing errors, random error data, and data that is lost or distorted. The data were eliminated or filled in appropriately. On the other hand, although the on-board data collected by the terminal at a certain point in time is a discrete data variable, it is actually a certain data in a time series, which is related to the previous data in the time series. Therefore, using previous relevant historical data, missing data or eliminated abnormal data can be predicted and filled, so as to obtain normal data sequences, and then provide more specific, accurate and reliable vehicle operation and statu...

Abstract

The invention discloses an internet of vehicles real-time data processing method and system. The method comprises the following steps of: monitoring terminal data of an internet of vehicles in real time; dynamically adjusting a monitoring time interval on the basis of a time difference value and fixed frequency combined monitoring strategy; investigating the monitored data in real time; eliminating the stale data in the monitored data; processing the investigated data in real time; cleaning and repairing the wrong data; and storing the processed data in real time through introducing a double-buffer technology. According to the method and system disclosed by the invention, more specific, correct and reliable vehicle running and state information can be provided in real time, the real-timeliness of transmitting and storing massive data of the internet of vehicles is improved and the integrity of the data is ensured.

Description

technical field [0001] The invention relates to a data processing technology of the Internet of Vehicles, in particular to a real-time data processing method and system of the Internet of Vehicles. Background technique [0002] In the era of "big data", with the wide application of 3S technology in the fields of vehicle positioning, intelligent management, and vehicle control, the Internet of Vehicles has emerged as the times require. The Internet of Vehicles is a computer real-time information system integrating data collection, data communication, real-time monitoring, data processing and data mining. The processing of real-time data is the core content of the whole system. The processing of real-time data needs real-time data generated by real-time acquisition or analysis and calculation. The processing process requires strong timeliness and reliability, and also generates massive historical data. After mining, analysis and calculation of these data, it can provide scie...
