Description
Technical field
The utility model relates to a kind of data base management system (DBMS), specifically a kind of distributed photovoltaic power station data base management system based on MongoDB.
Background technology
MongoDB is a database open source projects stored based on distributed document, and being a product between relational database and non-relational database, is that in the middle of non-relational database, function is the abundantest, as relational database.The maximum feature of MongoDB is that the query language that he supports is very powerful, and its grammer is similar to a little OO query language, almost can realize most functions of similarity relation database list table inquiry, but also supports to set up index to data.It is one towards set, pattern is Document image analysis freely.
Distributed photovoltaic power station is little with its pollution, the feature that environmental benefit is given prominence to more and more obtains the favor of people, but because power station distribution is looser, use traditional database the monitoring of traditional database to photovoltaic plant to be affected because of the operation that its search efficiency is low, handling capacity is little and be not easy to data.
Utility model content
In order to solve problems of the prior art, the utility model discloses the distributed photovoltaic power station data base management system based on MongoDB.
Based on the distributed photovoltaic power station data base management system of MongoDB, comprise data acquisition system (DAS), data transmission system, routing node server, rights manager, client, MongoDB database server, it is characterized in that: described data acquisition system (DAS), be distributed in different location, be connected with described data transmission system, the raw data collected is delivered to data transmission system; Described routing node server, for providing data inputting interface and data access interface; Described data transmission system is connected with router node server, by described data inputting interface, the data after data transmission system is sent to described MongoDB database server; Described client is connected with routing node server, for carrying out index or amendment by described data access interface to the data in MongoDB database server; Described rights manager is connected with routing node server, carries out the authority operated for the MongoDB database server described in point pairing.
Described data acquisition system (DAS) comprises power station equipment, control circuit, harvester and A/D conversion.Control circuit sends the information on instruction control harvester collection power station equipment, becomes computer-readable raw data, and be sent to data transmission system through A/D conversion.
Described data transmission system comprises exception test, data compression, data transmission and data decompression.The raw data that data acquisition system (DAS) transmits is removed invalid data through exception test and is obtained real time data, then is transmitted by real-time data compression, and carries out decompress(ion) to real time data before data arrive routing node server.
Described MongoDB database server comprises api interface, processor, storage unit; Described api interface is connected with the data access interface of routing node server, and described processor administers and maintains storage unit.
Described MongoDB database server comprises live database server and historical database server; Data in described live database server are stored in high-speed cache, and the data in described historical database server are stored in hard disk.
The beneficial effects of the utility model are: adopt the document-type MongoDB database towards set, have very powerful query function; Possess high handling capacity simultaneously, therefore meet the requirement of real-time property; MongoDB database is a open source projects, has very strong extendability; The form of distributed data base is adopted effectively to manage the data of photovoltaic plant for widely distributed, that data volume is large distributed photovoltaic power station.
