The Design And Implementation Of Distributed Cloud Storage Module Of Car Cideo Surveillance System

With the fast increase of Chinese vehicles, in order to improve the travel security of the vehicle, the demand for monitoring of the vehicle keeps growing up. For future investigation video requires persistence saved,, distributed cloud storage technology offers the perfect solution to the massive video files.This paper analyzes the car video surveillance system functional requirements.then gives the system function module division from the design point of view, and focus on the specific design of the distributed database module. The vehicle monitoring system will record video on a time slice divided into video files, and stored in HDFS, and video files in HDFS path and other video-related information recorded will be stored in HBase. This paper focuses on the design of distributed cloud storage and complex SQL-like query function module by using Expression analog functions in SQL statements, and then use ExpressionFilter and GroupBy query SQL-statement to achieve a class of queries. Then according to the design of each module,this paper gives the implementation code.Car video surveillance and on-demand systems design and implementation of this article, with advanced technology, good performance, and low cost to meet the majority of users real-time video surveillance requirements, while meeting user storage of massive video files quickly find and Ease of management requirements.This paper gives the design and implementation of the car video surveillance system, the car video surveillance system has advanced technology, good performance and low cost characteristics, it can meet the majority of users of real-time video monitoring requirements, and meet the users of massive video files storage, fast search and easy to manage requirements.
