A wireless radio frequency data screening device and method based on streaming computing

Abstract

The invention discloses a device and a method for screening radio frequency data based on stream-oriented computation. The device comprises a message queue kafka unit, a data source spout unit, a logic processing bolt unit and a cache management redis unit, wherein the message queue kafka unit receives and stores the radio frequency data; the data source spout unit monitors and pulls the currentlywritten data in the message queue kafka unit and analyzes the data; the logic processing bolt unit receives the analyzed data, inquires data, matched with the received data, in the cache management redis unit, performs matching screening within specific positive and negative time periods according to a preset processing logic and stores the matching-screened data into the cache management redis unit; and the cache management redis unit receives inquiry information of the logic processing bolt unit and returns a result and is used for storing the data which cannot be matched at the current time point. According to the device and the method for screening the radio frequency data based on the stream-oriented computation, the efficiency of data screening under radio frequency mass data concurrency is improved, the data waiting time in a conventional processing mode is shortened and the data processing timeliness is improved.

Description

technical field [0001] The invention belongs to the technical field of big data streaming computing, and more specifically relates to a wireless radio frequency data screening device and method based on streaming computing. Background technique [0002] The Internet of Things is another information industry revolution after computers, the Internet and mobile communications. The Internet of Things is based on the computer Internet, using technologies such as automatic radio frequency identification and wireless data communication to construct an "Internet of Things" covering everything in the world. Things”, and the core technology to realize this Internet of Things is radio frequency technology. In recent years, with the rapid development of the Internet of Things technology, a large number of applications of radio frequency technology and equipment, such as city-level vehicle checkpoint traffic tracking, item logistics tracking, etc., the subsequent daily radio frequency da...
