Abstract
The invention discloses a kind of method of utilization radar return diagnosis remote gauged rainfall station data exception, it includes 1, measures rainfall distribution map in region using radar return；2nd, rainfall value is surveyed at remote gauged rainfall station in pickup area；3rd, each remote gauged rainfall station actual measurement rainfall value in region is compared, draws the actual measurement rainfall ratio between each precipitation station；4th, using rainfall distribution map in the region obtained in step 1, the rainfall ratio of each remote gauged rainfall station position in region is extracted；5th, each remote gauged rainfall station actual measurement rainfall is compared than each remote gauged rainfall station rainfall ratio obtained with step 4, remote gauged rainfall station data exception station is drawn according to comparative result；The remote gauged rainfall station of prior art is solved because failure causes data measured bigger than normal or the abnormal conditions such as less than normal, control centre is difficult to judge, the problems such as control centre can cause forecast information distortion of controlling flood, influence flood control accuracy of the forecast using these abnormal data messages.
Description
Technical field
The invention belongs to remote gauged rainfall station failure detection technique, more particularly to one kind remote gauged rainfall is diagnosed using radar return
The method for data exception of standing.
Background technology
Remote gauged rainfall station is in occupation of very important position in flood control forecast system, and it is to be located at field condition to survey rain
That measures information predominantly detects one of device, and the physical fault for remote gauged rainfall station can be detected very easily, but right
Data exception failure in remote gauged rainfall station, then be difficult to judge, due to data measured caused by some failures at remote gauged rainfall station
The abnormal conditions such as bigger than normal or less than normal, control centre is difficult to judge, control centre can be led using these abnormal data messages
Cause flood control forecast information distortion, influence flood control accuracy of the forecast.
The content of the invention
The technical problem to be solved in the present invention：A kind of side of utilization radar return diagnosis remote gauged rainfall station data exception is provided
Method, to solve the remote gauged rainfall station of prior art because failure causes data measured bigger than normal or the abnormal conditions such as less than normal, in control
The heart is difficult to judge, control centre can cause forecast information distortion of controlling flood, influence flood control using these abnormal data messages
The problems such as accuracy of the forecast.
Technical solution of the present invention：
A kind of method of utilization radar return diagnosis remote gauged rainfall station data exception, it comprises the steps：
Step 1, using radar return measure rainfall distribution map in region；
Rainfall value is surveyed at remote gauged rainfall station in step 2, pickup area；
Step 3, by region each remote gauged rainfall station actual measurement rainfall value be compared, draw the reality between each precipitation station
Measure rainfall ratio；
Step 4, using rainfall distribution map in the region obtained in step 1, extract each remote gauged rainfall station institute in region
Rainfall ratio in position；
Step 5, each remote gauged rainfall station obtained by step 3 surveyed into rainfall than each remote measurement rain for being obtained with step 4
Amount station rainfall ratio is compared, and remote gauged rainfall station data exception station is drawn according to comparative result.
Beneficial effect of the present invention：
The present invention obtains the rainfall distribution map in region using radar return, obtains the rainfall ratio in any region
Value, then according to the actually measured rainfall value in remote gauged rainfall station in region, carries out two or two and compares, judge remote gauged rainfall station data
Abnormal website, convenient to repair as early as possible, the present invention is simple and practical；The remote gauged rainfall station of prior art is solved because failure causes
The abnormal conditions such as data measured is bigger than normal or less than normal, control centre is difficult to judge, control centre uses these abnormal data
The problems such as information can cause forecast information distortion of controlling flood, influence flood control accuracy of the forecast.
Embodiment：
A kind of method of utilization radar return diagnosis remote gauged rainfall station data exception, it comprises the steps：
Step 1, using radar return measure rainfall distribution map in region；
Rainfall value is surveyed at remote gauged rainfall station in step 2, pickup area；
Step 3, by region each remote gauged rainfall station actual measurement rainfall value be compared, draw the reality between each precipitation station
Measure rainfall ratio；
Step 4, using rainfall distribution map in the region obtained in step 1, extract each remote gauged rainfall station institute in region
Rainfall ratio in position；
Step 5, each remote gauged rainfall station obtained by step 3 surveyed into rainfall than each remote measurement rain for being obtained with step 4
Amount station rainfall ratio is compared, and remote gauged rainfall station data exception station is drawn according to comparative result.
