Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Core concept of the present invention is: in program broadcast process, for the stock information information of real-time update, respectively from collection link and broadcast controlling unit add hard real-time, thus ensure programming content can along with the data variation of transaction place real-time update.
Gatherer process is described below respectively and broadcasts control procedure.
Embodiment one:
With reference to Fig. 2, it is the method flow diagram of Real-time Collection stock information described in the embodiment of the present invention one.
It is leave in several dbf file that stock exchange pushes the transaction data of coming by satellite, and then provides in the mode (hereinafter referred to as shared file) that network file is shared, and the data of these files all can dynamically update in real time.
After the data in shared file change, program making center can directly from network terminal by upgrade data Replica to this locality.Compared with prior art, gatherer process described in the present embodiment does not need to arrange independent database server, does not more have the process of data base read-write, therefore saves acquisition time, ensure that the real-time of data acquisition.
Preferably, in above-mentioned reproduction process, if due to reasons such as unstable networks or network interrupt suddenly, can cause copying to local data incompleteness or mistake, if in this case continue to read data from this locality, the information of mistake will be read.Therefore, need local data to back up portion in addition, so as copy stagger the time for subsequent use.
It should be noted that the toy data base that local backup database used uses system to carry does not need to configure separately independently database server.Therefore, the present embodiment, on limited hardware resource platform, achieves real time data acquisition, and backs up in realtime.
In program broadcast process, can read data in real time from this locality and come to broadcast in real time, the process wherein controlling in this locality to broadcast is as follows.
With reference to Fig. 3, it is the method flow diagram broadcasting controlling stock information described in the embodiment of the present invention one in real time.
Step 301, reads data from this locality in real time;
Step 302, judges that whether data are normal;
If abnormal, then perform step 303; If normal, then perform step 304;
Judge that the whether normal reason of data has 2 points:
Be on the one hand because unstable networks or network interrupt suddenly, cause the stock information data from network-copy to this locality to fail normally complete completing, cause local data file incomplete further and normally cannot read data;
Be on the other hand because the places such as stock exchange push the incorrect or interim test data of the form of data of coming own, also can cause data exception.
For these reasons, just can be judged by two aspects:
On the one hand, if there is the error message that file cannot open in file reading process, just can assert it is abnormal state;
On the other hand, can after sense data, according to the Protocol document that stock exchange provides, whether the data format detected inside file is consistent with agreement, if inconsistent with agreement, just can regard as abnormal.
Step 303, reads Backup Data, and continues step 304;
Step 304, market demand represents.
Described market demand represents the real-time manufacturing and the broadcast that refer to and utilize the data read to carry out program credits.
In sum, said method avoids the time of using data database storing cost, the very first time can catch market consultation information quickly, and broadcast in real time; And, the safety of real-time broadcast process is ensure that by local backup.
Embodiment two:
Be described below by specific implementation.
With reference to Fig. 4, it is the method flow diagram of Real-time Collection stock information described in the embodiment of the present invention two.
Step 401, whether the shared file monitoring network terminal upgrades;
If upgraded, then perform step 402; Otherwise circulation performs step 401.
The realization of monitoring can have various ways, present embodiments provides following two kinds:
Be that API (an Application Programming Interface, the application programming interface) function adopting native operating sys-tern to provide carries out, namely create the dbf file attribute change situation that a thread removes real-time Sampling network end;
Another adopts the mode of timing (as: 100ms) to complete, and namely timing is gone network terminal to detect dbf file attribute in this time period and whether be there occurs change.
According to the difference of actual application environment and application demand, wherein a kind of listening mode can be selected.
Step 402, if upgraded, then copies to this locality by the shared file of renewal from network terminal;
Step 403, obtains wall scroll latest data from this locality;
Step 404, judges whether to need to store;
If need to store, then perform step 405; If not, then step 406 is performed;
The market demand that the present embodiment provides represents the direct broadcast that comprises program credits and uses captions Software for producing draw all kinds of stock market figure and broadcast.
Described storage mainly refers to the data message temporarily storing graphing needs with the form of data record, mainly comprises the data of two aspects: one is timesharing trend graph data, and two is day K graph datas.These two parts data are all Real-time Collection and store, and timesharing trend graph data just store the data on the same day, and day K graph data is the storage data of up-to-date 100 days.
Step 405, stores wall scroll latest data, and continues step 406;
Latest data and the data originally recorded is needed to compare during interim storage:
If record corresponding with latest data in the data originally recorded, then show that latest data is the data newly increased, need latest data to add in data record;
If latest data is the renewal to former data, then need latest data to be replaced corresponding former data.
Step 406, backup wall scroll latest data.
Whether no matter be namely need temporary storaging data for drawing, final collection all needs at local backup after coming.
With reference to Fig. 5, it is the method flow diagram broadcasting controlling stock information described in the embodiment of the present invention two in real time.
Step 501, selects broadcast content;
Namely select to broadcast personal share information, or broadcast fund information, or broadcast Index of Shanghai Stock Exchange information or rank etc.;
Step 502, reads real time data information;
Namely the latest data file received is read from this locality;
Step 503, judges that whether the data read are normal;
If abnormal, perform step 504; If normal, perform step 505;
Can judge whether data file can be opened, and whether data format is consistent with agreement, confirms that whether data message is normal.
Step 504, reads the data message of backup, continues to perform step 505;
If the data exception read, can also read from local backup;
Step 505, data filtering process;
Namely filtration treatment is carried out to read data, therefrom filter out the data of needs.
Due to this locality storage is personal share, fund, index etc. the recording data information that all stock exchanges go on the market, if so need the information broadcasting wherein a personal share or fund, just needs extract from read data file.Such as: if select to broadcast Index of Shanghai Stock Exchange information from broadcast control inerface, so data filtering filters out code in other words from read file is the " 000001 " data message of record.
