Embodiment Construction

[0020] HBase is a distributed storage system in the Hadoop ecological environment. Distributed file system HDFS lacks

[0022] Hadoop video monitoring data is the video image collected by the Internet of Things camera sensor, and monitoring picture data

[0032] There are also obvious differences in the adaptability to the underlying data storage system due to different data types. structured data

[0034] The data has better adaptability. Due to the unstructured data model of the storage system due to less internal constraints

[0035] The efficiency is generally higher than the relational model; but due to the dependence of the numerical data on the transaction and the stability of the structure

[0037] etc. are more suitable for storage in an unstructured storage system.

[0040] (2) traverse the query index table in the memory to perform rule verification.

[0044] Through this method, all Map nodes in the cluster can execute different verification rules concurrently. like...

Abstract

The present invention claims to protect an agricultural data monitoring method under the hadoop environment, which stores the original data records in the agricultural system through the storage method under the hadoop environment, uses a non-primary key index method to index the verification field, and uses a grid coding method , use the heterogeneous data layer to store the data structure of the Hbase object, decompose the task based on the structural model of the Hbase object, use HBase to establish a timestamp index for the original data record and use the parallelization method of MapReduce to complete the data monitoring of the verification rule. The present invention can solve the problem of massive data quantification through the horizontal expansion of distributed clusters in an efficient and scalable manner; solve the inconvenience caused by data isomerization through unified modeling of heterogeneous data; establish auxiliary queries for fields involved in verification rules Indexes to support efficient query processing when validation rules are executed.

Description

An agricultural data monitoring method in hadoop environment technical field The present invention relates to computer technology field, relate in particular to a kind of agricultural data monitoring method under hadoop environment, This method is efficient and scalable. Background technique Since the beginning of the 21st century, the rapid development of computer network and sensor technology, the wide application of agricultural Internet of Things In order to bring the world into the era of rapid development of the Agricultural Internet of Things, my country has also established a large number of related agricultural Internet of Things systems. This These systems have played an important role in agricultural environmental monitoring, disaster warning, crop growth monitoring, agricultural product safety and other fields. A series of important results have been obtained. In this process, with the continuous development of the agricultural Internet of Things system...
