Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
The all weather datas of native system, from external source, might as well be defined as data center server.Live data reception and monitoring modular for the cycle with 45 seconds, were set up SFTP with data center server and are connected, and according to the listed files downloading all kinds of meteorological live data on regular inventory traversal server, itself and local downloaded file list buffer memory were compared.When having identified new file, carrying out downloading and this filename has been added in listed files buffer memory.In listed files buffer memory, the life cycle of every record is 1440 minutes, the data center server files rise time more Zao than present system time 24 little time more than file be regarded as non-live data, (system manager can revise every download rule) will not be downloaded according to pre-defined rule.The data class downloaded comprises conventional ground observation data, sounding weather data, weather radar base datum, encryption automatic weather station observation data, Lighting position machine data, Wind outline data, GPS steam data etc.If N continuous minute does not detect, and data center server has new file generated, this module sends shortage of data early warning mail by smtp protocol to the email address preset, and the definition of N is as shown in table 1 here.This module is also responsible for the data file regularly sectional lists storage that will have downloaded, and provides unified data access interface to other modules of native system, and provide data to other modules on the one hand, another aspect receives and stores the data of other CMOS macro cell.This module also possesses the function of stale data timing cleaning, and the rule of cleaning can be set by system manager, and its regularization term mainly comprises file type, file size, bibliographic structure, expired timeliness, filename coupling etc.
Table 1
File type N value (unit: minute)
Conventional ground observation data 360
Sounding weather data 1140
Weather radar base datum 12
Encryption automatic weather station observation data 10
Lighting position machine data (not monitoring this)
Wind outline data 60
GPS steam data 120
Weather radar data modular converter is responsible for the data layout of base data to be converted to planimetric rectangular coordinates by polar coordinates, this transfer process is from base data first elevation angle, first position angle, radially progressively outwards move forward into row-coordinate conversion by the center of circle, formula is:
In above formula, x, ythe coordinate in plane right-angle coordinate, rthe maximum radius that base data body is swept, nspan be 2 ~ 8, nthe radar return image granular sensation that larger conversion is finally drawn afterwards is more careful, nthis transfer process speed less is faster. position angle, x 0 , y 0 the position of true origin when representing that its center of circle under polar coordinate mode corresponds to planimetric rectangular coordinates respectively.For the planimetric rectangular coordinates point that angle between adjacent two position angles of base data comprises, anti-distance weighting is adopted to carry out interpolation.In plane right-angle coordinate, the region value do not covered under polar coordinates is-99.
Encryption automatic weather station data checking module is responsible for carrying out quality inspection respectively to each meteorological element, method comprises the time consistency inspection of the inspection of historical climate extreme value, past 5 minutes, 1 hour, 12 hours same key element, physical quantity relational checking between different key element, the space interpolation inspection etc. of same key element.For checking out abnormal record value, adopt-9999 marks.
Data packing compression module is responsible for that above-mentioned all kinds of weather data is carried out merging and is packed and compress, then split into several nominal amount file (here preset ratings be 128KB, the too small data traffic that can increase non-data file transfer of this value, this value crosses data traffic during conference increase data re-transmission), store in a binary format.When the fundamental purpose of this module is in order to mobile terminal accessing, fully reduce file size, reduce volume of transmitted data, and when data transmission exception, only need again the data file of transmission abnormality.
The outbound data Push Service that data service module provides access rights controlled, an open designated port monitors the connection request of each mobile terminal on automatic network, ICP/IP protocol and mobile terminal is adopted to connect, access authorization is given for the connection be verified, adopts udp protocol to push the data file generated through above-mentioned steps to mobile terminal.
Data access module is under mobile terminal possesses the condition of Internet access ability, and according to user operation instruction, send connection request to the IP of data service module and predetermined port, this request also comprises the account relevant information of user.If data service module is by checking to this account, then feeds back a protocol information to mobile terminal, inform the port numbers of data-pushing, this module namely thus port and data service module set up UDP and be connected, carry out data receiver.Due at data, services end, each complete data message is split into the small documents of several 128KB, the numeral of mark sequencing is comprised in filename, each partial data message is except last small documents, if the volume of alternative document is not equal to 128KB, this module is then to data service module request retransmission.
The data that data processing module is responsible for having downloaded decompress, and according to the instruction of user interactive module, carry out the processing process of data, as singly referred to the scope of streaking radar return on screen by user, calculate the vertical section of radar body total number certificate, then result of calculation transferred to graphic plotting module carry out graphic plotting and represent on a terminal screen.For another example, according to the Time effect forecast that user sets in terminal, use the radar data downloaded, carry out the Extrapotated prediction of radar return, and Quantitative Precipitation estimation etc.
The result of the weather data after decompress(ion) and various interactive computing is carried out graphic plotting by graphic plotting module in charge, carry out patterned data display on the screen of the mobile terminal, reflect the space distribution situation of each meteorological element intuitively, the form of graphic exhibition comprises based on the website distribution plan of geography information, website meteorological element hum pattern, isogram, the figure that colors in, curve map, radar echo map, radial velocity map and radar profile etc.
User interactive module is responsible for the operational order accepting user, is included in touch screen and singly refers to click, singly refer to slip, the slip of two finger etc., and the mouse, keyboard operation etc. on notebook computer.The fact monitoring of customization and the making of forecast model products and displaying is completed according to these instruction synergistic data processing modules and graphic plotting module.
Thus, shoring of foundation is provided for professional and technical personnel carries out subjective synoptic analysis, forecast and decision-making.
