Specific embodiment
Below with reference to specific embodiment, the present invention is described in further detail, it is described be explanation of the invention and
It is not to limit.
The design of 1 system architecture
The composition of this system uses " cloud-net-end " three-tier architecture, specifically have berth lock and sensor executed as order and
Information acquisition unit, handheld terminal use unit as parking service, and each parking management server is that parking management cloud platform mentions
For service support, parking management cloud platform externally provides parking management service.This system framework is as shown in Figure 1：
" end " refers to intelligent space lock, empty wagons level detection sensor and hand-held mobile terminal.Intelligent space lock is for acquiring parking stall
Status information simultaneously controls the parking stall right to use, links with empty wagons level detection sensor and realizes that parking user obtains and release parking stall uses
Power.Hand-held mobile terminal is by installing this system parking APP, parking stall resource and other parkings clothes in real-time acquisition system
Business.
" net " includes the wide area network in parking lot between local area network and parking lot and cloud platform, be connection this system " end " and
The data channel of " cloud ".In this system, local area network uses the ZigBee-network of self-organizing, low-power consumption in parking lot, it is ensured that network
Quality reduces cost of arranging net；Wide area network uses WIFI network between parking lot and cloud platform.
" cloud " refers to parking management cloud platform, and each parking position data, processing are stored and handled using cloud computing technology
Predetermined request provides parking management and parking service for parking lot and parking user.
Parking lot and parking user be it is completely isolated, established join by common parking management cloud platform each other
System, parking lot provides parking stall during this process, and user is that parking service obtained pays expense, is consumption between the two
With the relationship consumed.
2 establish database segment page index
The WiFi module of berth lock carry out data transmission to server end and server end to the end APP carry out data biography
When the two defeated stages, the database of server end will be increased, delete, change, looking into four basic operations.However for as this
The server of the such big data type of system, to carry out corresponding data manipulation, efficiency, speed, memory space clearly cannot
Meet user demand.
To solve this contradiction, the invention proposes following solutions：
A kind of big data fast indexing method based on segmentation paging system cloud, including segmentation paging system allocated phase, server cloud
Index generation phase, Lucene accurate search phase：
Step1. segmentation paging system allocated phase need to be completed to configure as follows：
By database according to from different places or other divide table standard to be divided into multiple sections, each section of segment structure is identical.Often
A section manages multiple tables respectively, and the table structure of each segment management is identical, and table quantity is different.
The data structure form for needing to store in every table is：Index value+data.Wherein index value is that server is given birth to automatically
At.
Step2. server cloud indexes generation phase, and main process is as follows：
Due to the irrelevant property between each section and each page, server is easily achieved parallelization data processing.In order to
It realizes big data quick indexing, stores each section of index value in the beginning of the page of every table, this means that this page can be corresponding
Section inquire.
Each computer in a group of planes is each responsible for a part of a page or a page, and which achieves segmentation paging systems
It is nested, it is important to distinguish the standard of segmentation paging.In addition this standard can build table and specially record, when server needs additions and deletions to change
When looking into, this table is loaded first to find corresponding segmentation paging standard.
Whenever there is new data to be inserted into certain one page, a certain in other words section has created a page, server database
It is automatically generated segmentation paging system index value.Generate the method that the technology of index value can use clustered index.Due to the number of segmentation paging system
Big data quantity is divided into compared with toy data base according to storage form, therefore every computer in a group of planes generates the mistake of index
Journey is relatively simple, and it is more satisfactory to directly generate clustered index.
It should be noted that if entire database, which is indexed, to be needed to load 3 times without nesting.It is load for the first time
It is segmented the table of paging standard, finds each standard；Second load is that different sections is loaded from server cloud, and by section
Number find corresponding segment index value；Third time load is inquired using Lucene pages of index, and the data of needs are found.
Further, the segmentation paging system path for recording each step index, in case the return of subsequent data directory result
Journey.
Step3.Lucene accurate search phase, this stage mainly complete quick lookup and index knot to data in page
The return work of fruit.
Full-text index/search function may be implemented in the api interface of Lucene.If to find a certain line number in certain one page
According to can directly inquire the page index value generated in second step and be looked into because index value is sequentially generated according to certain
Workload can be reduced when inquiry, improve search efficiency.It can be directly realized by index function using the api function of Lucene, efficiency is very
It is high.
After finding indexed results, the path for the segmentation paging recorded before, backtracking to server cloud are utilized
?.External APP mobile client can find data required for cloud at this time.
The flow chart of segmentation paging system data directory is as shown in Figure 6.
