Problems solved by technology

Therefore, those centralized data computing models with limited performance, capacity, and scalability in the past and complex management are no longer suitable for storing and processing big data with such characteristics. Therefore, it is urgent to design a decentralized / Self-organized distributed location service big data system prototype architecture, covering different stages of data transmission, storage, processing, sharing, retrieval, analysis and visualization, to achieve efficient management of location big data
[0005] 2) In the location big data environment, the use of large-scale data objects will inevitably lead to the existence of user concurrency control problems
[0006] 3) In terms of the integration of multi-source information and location services, the multi-source and heterogeneous characteristics of location information make it difficult to correlate analysis and value in the mining process.
When the sensor coverage area is narrow, the problem of incomplete data is obvious

Embodiment 1

[0053] The present invention is described in detail below in conjunction with accompanying drawing:

[0054] Embodiments of the present invention provide a method for navigation and location services based on a big data system, including the following steps:

[0055] Step 1: Install Cloudera-Manager in the server, and use Cloudera-Manager to install distributed memory computing framework, distributed file system, data warehouse tools, log collection system and distributed message subscription system in the server system to form a big data system;

[0056] Step 2: Build a Mashup network aggregation platform;

[0057] Step 3: Utilize the Mashup network aggregation platform, the log collection system and the distributed message subscription system software to collect user sign-in information, and record the user sign-in information as original data;

[0058] Step 4: Perform data cleaning on the original data to obtain first data, and store the first data in the distributed file ...

Embodiment 2

[0080] Such as figure 1 Shown, the basic process of the present invention is as figure 1 shown.

[0081] The first data is the geographical location data of the user, which is obtained by means of vehicle-mounted or mobile sensors and uploaded to the Internet through the network.

[0082] Use the network aggregation tool Mashup combined with the Flume log collection tool and the Kafka message system to collect location data information on the Internet and store them in the distributed file system HDFS. The collected original data is deduplicated to realize data cleaning, and the processed data Stored in HDFS.

[0083] The GIS display module reads data from HDFS, and uses the distributed computing framework to perform statistical analysis on these data. The analysis results are stored in Hive and relational databases according to the situation, and are called by the corresponding web application and combined with tools such as Baidu map. Visual display.

[0084] Cluster the...

[0105] Example 1: Route recommendation

[0106] Such as image 3 As shown, the route recommendation implementation process is as follows:

[0107] Data collection: The design plan of the entire application is to track the browsing routes of historical users, use the user's check-in data in the scenic spot as the source of ST (space-time) data, further analyze and dig out valuable information, and use it as the basis for subsequent real-time route recommendation. We assume that at the same time, there will be hundreds of users clicking and signing in. We believe that the data source will generate a mega-level of data every 1-2 minutes. In order to ensure that the data can be collected completely and without errors, a Highly available data collection framework for data collection. Flume is a real-time log collection framework generated under such a technical requirement, which can well meet the conditions. Data needs to be stored in system files while data is being collected....

Abstract

The invention relates to a navigation and location service method based on big data system. The method comprises the following steps: firstly performing data collection by using a network aggregationplatform mashup to combine a distributed log collection system Flume and a distributed message subscription Kafka; secondly, performing data preprocessing and a de-duplication operation original data;and finally performing statistical analysis, GIS display, clustering analysis, service recommendation, and RICK algorithm processing on the acquired data to generate route map model, and perform route recommendation. In the method disclosed by the invention, the source of the location data is from the internet, and the data size is numerous and different from the way of directly using the sensorin other patent and systems, and the clustering and like data mining is performed in combination with the user data; the service recommendation and the route recommendation is performed on the user according to the user analysis result, time and location, the defects that the existing recommendation method is low in accuracy rate, and slow in speed, and the method can be applied to navigation in the scenic spot and like special fields.

Description

technical field [0001] The invention relates to the technical field of mobile location services, in particular to a navigation and location service method based on a big data system. Background technique [0002] Location based service (LBS for short) is an emerging mobile computing service in recent years. With the development of indoor and outdoor seamless positioning technology and enhanced system technology, the positioning accuracy continues to improve. In the daily production and life process, the public's demand for location services is also increasing. Emerging Internet applications such as the Internet of vehicles (IOV for short), mobile social networks, and microblogs are changing with each passing day. On the one hand, positioning devices such as GPS and Wi-Fi built into mobile devices such as mobile phones and car navigation can directly obtain moving objects. Accurate location information at any time, and publish the collected location information through vario...
