Embodiment Construction

[0052] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation methods, features and methods of the dirty data identification method and data cleaning method proposed according to the present invention will be described below in conjunction with the accompanying drawings and preferred embodiments. Its effect is described in detail below.

[0053] see figure 1 , the present invention relates to a dirty data identification method, comprising the following steps:

[0054] Step S1, defining a domain rule base for data cleaning.

[0055] Taking Sanfang pile data as an example, according to business requirements, the fields that need to be cleaned in each tripartite pile data record (identified by a unique pile id) include: address information field, business (service) time field, etc. According to the characteristics of the tripartite pile data, for each field that needs dat...

Abstract

The present invention provides a dirty data identification method and device, a data cleaning method and device, and a controller. The dirty data identification method comprises the following steps: extracting a domain rule base, wherein the domain rule base comprises one or a plurality of first decision rules and one or a plurality of second decision rules; identifying dirty data in a data fieldaccording to the domain rule filtering the data field by the first decision rule, and judging the data field as dirty data if the data field matches any one of the first decision rules; if the first decision rule is not matched, filtering the data field using the second decision rule. The dirty data identification method of the invention improves data cleaning efficiency and cleaning accuracy.

Description

technical field [0001] The invention relates to a data processing method, in particular to a dirty data identification method and device, a data cleaning method and device, and a controller. Background technique [0002] Charging piles are an integral part of electric vehicle charging equipment. In the charging resource management and monitoring system, it is often necessary to access the data of the charging piles of the third-party platform (referred to as the three-party pile) to meet the needs of the business, and the quality of the three-party pile data has a direct impact on the upper-level business, so in the three-party pile Data cleaning is required before entering the charging resource management and monitoring system. Data cleaning can be described as using a series of logical operations to detect dirty data from a large amount of raw data and repair or discard it. If the data cleaning of the three party piles is done entirely by manual assistance, the efficienc...
