In embodiments of the present invention, be undertaken by the data processing software on central station server 30 to correcting of abnormal data.
Should be appreciated that above-mentioned implementation environment be only the data revision method that provides of the embodiment of the present invention a kind of implementation environment of being suitable for, the present invention is not produced in the scope of abnormal data correction method and limits.
Fig. 2 shows the flow process of the data revision method that the embodiment of the present invention one provides, and for convenience of explanation, part related to the present invention is only shown.
In step s 201, obtain a time period, read the data record in the described time period from database, formation curve chart and data list also show.
In embodiments of the present invention, database is through automatic revised database.User, according to meteorological regulation, first determines the state of curve, then judges the approximate range of exceptional data point, and then rake about among a small circle within large time period.Such as, first open the data and curves table within two days, after finding that certain day data fluctuation ratio is comparatively large, be specifically switched to the data of this day, then time range to be narrowed down to hour, then concrete data point judged and revise.
In embodiments of the present invention, the data record described in step S201 comprises the observation time of observed quantity, observation value and Data Identification.
In embodiments of the present invention, described Data Identification comprises data exception decision state mark and data revision status indicator; Described data exception decision state mark comprises normal value, lacks measured value, negative value or exceptional value; Described data revision status indicator comprises automatically to be corrected unmodified data record, automatically correct Update Table record, manually corrects Update Table record.
In embodiments of the present invention, the standard of described abnormality juding performs about abnormal data criterion according to meteorology, concrete, scarce measured value is survey the observation data that numerical value is sky, the observation data of negative value to be observation value be negative, exceptional value is there are the data not meeting weather data Changing Pattern in the weather data of Continuous Observation, and normal value is there are the data meeting weather data Changing Pattern in the weather data of observation.
Such as, article one, data are judged as exceptional value in the stage of automatically correcting, be judged as normal value again in the stage of manually correcting, data in this case should for being considered as abnormal data, and its mark distinguishing normal data experienced by the amendment automatically correcting the stage and the amendment manually correcting the stage.
As a preferred embodiment of the present invention, obtain a time period, from database, read the data record in the described time period, formation curve chart and data list when showing, to the abnormal data in curve, highlight with special formal classification.
In embodiments of the present invention, described abnormal data comprise data in data record be denoted as abnormal data mark or observation value was modified, data are corrected amendment automatically.
In embodiments of the present invention, the icon that described special shape comprises data point display is different with the icon of normal data points with the state of icon, and the difference of display icon includes but not limited to the difference of the size of icon, shape, filling pattern; Display icon state difference includes but not limited to icon flicker, the mode of beating, frequency difference.
