2) obtain multiple id set according to initial consonant sequence and Serial No. are retrieved in index module, and obtain all id intersection of sets collection；
3) judge that whether all id intersection of sets integrate as empty set, if it has, then perform step 4), if it has not, then perform step 5)；
4) prompting key word mistake, it is desirable to re-enter；
5) in distributed memory system, the model data of correspondence is inquired about and reads according to the id in occuring simultaneously.
In distributed memory system, first set up a vang and draw, then pass through index, obtain all id satisfied condition, further according to id, inquire data, so, in ideal conditions, by an original database access, become the access of three internal memories, it is possible to improve inquiry velocity.
Described step 1) specifically include step:
11) it is loaded into search key, and extracts the initial consonant of all of which Chinese character, and form initial consonant sequence；
12) judge whether search key exists numeral, if it has, then perform step 13), if it has not, be then parsed；
13) extract all of numeral, and form Serial No..
Described step 2) specifically include step:
21) an id set is obtained according to each initial consonant in initial consonant sequence, particularly as follows: index obtains containing the power station of this initial consonant or the id that circuit is corresponding in all titles in index module；
22) an id set is obtained according to each numeral in Serial No., particularly as follows: index obtains containing the power station of this numeral or the id that circuit is corresponding in all titles in index module；
23) all of id set is sought common ground.
Described step 5) specifically include step:
51) title of the power station corresponding for all id in common factor or circuit is shown to user, user after selecting, it may be judged whether model data can be inquired, if it has, then perform step 52), if it has not, then perform step 53)；
52) power station chosen according to user or the id of circuit inquire about the model data of correspondence in distributed memory system；
53) power station chosen according to user or the id of circuit inquire about the account information and model data that obtain power station or circuit in data base, and store the model data obtained in distributed memory system according to the id in account information.
Described account information includes power station or the id of circuit, title, electric pressure and affiliated unit.
A kind of three-dimensional platform data fuzzy query method based on distributed memory according to claim 4, it is characterised in that described step 51) in the sort by of title of power station or circuit be: the number of times that the model data of this power station or circuit is read.
Described sort by is particularly as follows: the number of times that is read within the setting time of the model data of this power station or circuit.
Compared with prior art, the invention have the advantages that
1) under three-dimensional platform, fuzzy query is carried out according to initial consonant sequence and Serial No., when client uses phonetic initial consonant to carry out fuzzy query facility information or other three-dimensional related datas to server time, utilize distributed memory can improve inquiry velocity so that client says that scene renders faster.
2) distributed memory is utilized can to promote the access speed of data, simultaneously, decrease the access pressure of server, reduce period of reservation of number, data are made to be timely fed back to client, promote Consumer's Experience sense, under the environment that some are real-time, utilize distributed memory can also ensure the real-time of data.
3) by the reading times of corresponding model data, the title of power station or circuit is ranked up, it is possible to improve Consumer's Experience.
4) data in distributed memory system preserve according to being read number of times, improve internal memory utilization ratio.
5) method that we adopt is, in distributed memory, first found an id index, this index is made up of a series of set, by this index, the all id satisfied condition can be found, because that index is only deposited is id, the space occupied is not as big, so all data in data base all can be established index.Then, all of inquiry of client, it is all first pass through this index to find the id of correspondence, inquires about data again through id.
