Problems solved by technology

Bloom filter (Bloom Filter, BF) is an efficient filtering judgment algorithm, processing judgment requests on massive data has the characteristics of high time efficiency and low space requirements; but on the other hand, Bloom filter is used in manufacturing In information retrieval, there is a disadvantage of high misjudgment rate, and the function is limited to filtering judgment, which does not constitute a relatively complete technical chain for massive manufacturing data retrieval

Embodiment Construction

[0054] Such as figure 1 As shown, a method for mass manufacturing data access in intelligent workshop management of the present invention, specifically includes the following steps:

[0055] Step 1. Receive request data and obtain access query parameters. Use the database partitioning technology to divide the data source into smaller parts, partition the manufacturing data from multiple dimensions, and obtain multiple data slices after the division:

[0056] Step 1.1. In this embodiment, a distributed database is used to manage massive manufacturing data. Firstly, the vertical sharding technology is used to shard the manufacturing data in terms of business, and then the manufacturing data is sharded horizontally in the dimension of site and time;

[0057] According to the above sharding rules, the manufacturing data is vertically sharded on business and hot data, among which the business is divided into equipment center, product center, etc.; on hot data, data is divided acco...

Abstract

The invention discloses a manufacturing data extra large amount access method of intelligent workshop management, the method comprises the steps of conducting delimitations to data sources through using a database sub region technique, assigning a corresponding Bloom filter device for every delimited data source; designing a multipath Bloom filter device, adopting a concurrent mode to carry out filtrations and judgments; through the filtered Bloom results locking the data subdivision of the 'potentially existed' requested data, then through a search technique, obtaining the target data, the method provides accurate and highly efficient manufacturing data extra large amount access services for intelligent workshop management and supporting applications thereof.

Description

technical field [0001] The invention relates to the fields of intelligent manufacturing and data retrieval, in particular to a method for accessing massive manufacturing data in intelligent workshop management. Background technique [0002] With the development of industrial intelligence, especially the large number of applications of smart devices, in the intelligent workshop management and its supporting applications, the rapidly growing manufacturing data has the characteristics of huge volume, variety, and low value density. ), high processing speed (Velocity) characteristics. How to accurately and efficiently retrieve target data from massive manufacturing data has become a key problem to be solved urgently. [0003] In the process of researching technical solutions, we have optimized from the perspectives of database table partition (Partition), index (Index) and cache (Cache), but when the manufacturing data reaches a certain level, it still cannot meet the performan...
