Brief description of the drawings
Fig. 1 is the schematic diagram of the present invention.
Embodiment
Present pre-ferred embodiments are provided below in conjunction with the accompanying drawings, to describe technical scheme in detail.
As shown in figure 1, reproduction formula satellite test data playback system of the present invention includes satellite test data storage terminal, surveyed
Try data extraction terminal and satellite test data playback terminal.
Wherein, satellite test data storage terminal includes database and database interface layer, for satellite Various types of data
Receive, store and extract；The data received are serialized, because the data due in of each data source has necessarily
Deviation, but the arrival rate of all data is close or suitable, therefore in data serializing, in order to improve the effect of serialization
Rate simultaneously reduces the requirement to database, the pattern serialized using timing data, i.e., the data received is kept in, timing is right
Temporary data are once serialized, and then by the data write into Databasce of serialization, the data in write into Databasce are needing
By data read-out from database when playing back.
Test data extraction terminal response user operation, carries out data query business, while enter row format to test data
Decoding and data distribution；
Satellite test data playback terminal is completed to telemetry, ground installation data, remotely-sensed data, bus data and had
The playback and reproduction of line gathered data.Satellite test data playback terminal is the display system of whole system, provides the user number
It is investigated that seeing and showing service, service is checked except data are provided to current data with existing, data form service, tendency chart clothes are also provided
Business, dynamic image service.List service provides the related data at playback moment, supports data export to secondary point of data
Analysis；It is mainly used for data export and word checks mode, for the mutation analysis of data and the secondary analysis of other instruments.
The tendency chart service checked for some parameter or the trend of a certain group of parameter of change, the characteristics of to data variation
Analyzed, the main form that X-Y scheme is provided, including with time shaft and using another parameter as with reference to two kinds；The shape of tendency chart
Formula provides the specified data trend variation diagram of a period of time before and after the playback moment, to the dynamic characteristic of analyze data.It is described dynamic
The service of state image is directed to image of frequency spectrum, remote sensing bag etc., and it, which is mainly characterized by one group of data at a certain moment, can characterize one
State or piece image, and image dynamic change, therefore can not be represented with a point or a figure, dynamic shadow can only be passed through
As representing；It is mainly used in the playback of the view data such as rf data intermediate frequency modal data, remotely-sensed data, plays back the image at a certain moment
Data.
The all types of data of the satellite test data storage terminal-pair use the serialization processing mode of unified form
Ensure data format and the existing compatibility that terminal is presented.
The satellite test data storage terminal is disappeared to ensure the independence of data receiver and data storage using the producer
The person's of expense model carries out the reception and storage of data, ensures the integrality and correctness of data receiver.
Database interface layer shielding database basic operation in satellite test data storage terminal, shields sql like language, right
Outer offer data base read-write access interface.
Satellite test data plays back terminal in addition to providing the panorama playback system of all total datas, also provides and is directed to certain
The independent playback of similar properties data.
All serialized data communications are realized using TCP/IP network interfaces in satellite test data storage terminal, are
The communication of other data uses protocol conversion mode in system.
Satellite test data storage terminal provides conventional configuration TCP (transmission control protocol)/IP and (interconnected between network
Agreement), UDP (UDP) agreement, realize the data to receiving after basic TCP/IP, UDP data transfer
Serialized, by the data write into Databasce of serialization.
Satellite test data storage terminal selects Key- Value types non-relational database come realize the quick search of data and
Fast reading and writing, Key values are selected the time, the data after the corresponding serialization of Value values.
The present invention realizes the distribution storage and management of data using distributed data base；By data in database according to dividing table
Mode is stored, i.e., is grouped data, and packet storage is carried out according to Fixed Time Interval.
Storage core of the database as the present invention, the design of its list have a major impact to the performance of whole system, are
The search efficiency of data is improved, a point table is carried out to data according to the period, due to the particularity of ground test, carried out daily
Test event it is inconsistent, when carrying out data analysis, often analyzed for a certain day data, therefore divide table in data
When, each day data is carried out individually to divide table, the table that the data of every day are independent as one is stored in database.
In data storage, because the data volume of remotely-sensed data is big, it is serialized separately as a kind of data, just
In the network throughput for reducing whole system.Other data are subjected to unified serial, because data due in is different, therefore
Data in the data of each group of serialization in database may differ, and its put in order may also be different, therefore
Need that data are individually identified during Deserializing.
Because the data of each group of serialization data type contained therein is different, therefore its length is also different, in database
In, the length of each group of data has difference.
Due to using Key-Value type database, therefore the inquiry of database depends on the inquiry to Key values,
Value values are as return value.
Test data extraction terminal is used for the data query requirement of relative users, and row of playing a reversed role is carried out to the data of serialization
Change, the playback of data is carried out by former agreement and data transfer mode, be easy to, using current existing data real-time reception terminal, carry
The applicability of high offline playback；Data forwarding is carried out according to former form to the data after Deserializing, keeps original data to assist
View, original real-time system is adapted it to, the real-time monitoring terminal of utility carries out data and checked, improves the applicability of system.
Test data extraction terminal is also screened to data, when user selects remotely-sensed data, by all numbers for meeting time requirement
Read according to from database, according to demand played back specific data after carrying out data Deserializing；When user is non-selected distant
Feel data when, other kinds of serialized data is only read from database, after to data carry out Deserializing operation, according to need
The corresponding data of extraction are asked to be played back.
The present invention supports to play back and check while diversiform data；Support the independent playback of diversiform data, there is provided number
According to a variety of presentation modes such as list, tendency chart and dynamic image；Using Key-Value non-relational databases to unified form
Data write and read, improve efficiency data query.
Particular embodiments described above, technical problem, technical scheme and the beneficial effect of the solution to the present invention are carried out
It is further described, should be understood that the specific embodiment that the foregoing is only of the invention, be not limited to
The present invention, within the spirit and principles of the invention, any modification, equivalent substitution and improvements done etc., it should be included in this
Within the protection domain of invention.
