Problems solved by technology

[0004] Most of the traditional data cleaning methods are based on disk data files. The cleaning process is accompanied by a large number of I / O operations on the disk. Although query optimization can improve efficiency to a certain extent, when faced with massive data, frequent I / O operations still directly become the bottleneck that affects performance

Embodiment Construction

[0021] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0022] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0023] Since some newly established data structures and algorithms involved in the present invention need to be used in specific implementation steps, these data structures and algorithms involved are described first.

[0024] Concept 1. UDB (Uniform-Delicate B-Tree) tree,

[0025] Definition: This is a kind of B-tree, which conforms to the general definition of B-tree structure. Since B-tree is a data structure that has reached a consensus i...

Abstract

The invention discloses a cleaning method of data of the internet of things, and relates to the field of data process of the internet of things. The method includes the following steps: (1) operators obtains original data of the internet of things through web service, (2) the operators reconstruct the original data and store the original data in a memory, (3) the operators reassemble the reconstructed original data into a UDB tree, and (4) a preset rule is read and data cleaning is carried out. The data cleaning is carried out according to the preset rule so as to reduce input / output (I / O) operations to the largest extent, and therefore traditional performance bottleneck problems can be solved fundamentally.

Description

technical field [0001] The invention relates to the field of Internet of Things data processing, in particular to a method for cleaning Internet of Things data. Background technique [0002] With the development of various devices and technologies such as sensors, radio frequency identification (RFID), global positioning systems, infrared sensors, laser scanners, gas sensors, etc., everything in reality will be possible to monitor, connect, In the process of interacting objects or processes, various required information such as sound, light, heat, electricity, mechanics, chemistry, biology, and location are collected, and a huge network is formed by combining with the Internet. Such a huge network is called a thing. networking. [0003] Due to the above characteristics of the Internet of Things, in the process of collecting data, a large amount of massive data with different formats and different meanings is generated, and how to clean the data according to the needs of use...
