Point 204 corresponding with the real time water level is obtained on water level-storage-capacity curve 201 in one quadrant.Further according to point 204 in first quartile
The projection of middle X-axis obtains the current storage capacity of the corresponding reservoir of point.Specifically, can be one and X-axis of strokes and dots with real time water level
Parallel straight line, the joint of water level-storage-capacity curve 201 in the straight line and first quartile are corresponding with the real time water level
Point 204.It is similar, can be starting point with the corresponding point 204 of the real time water level, draw a straight line parallel with Y-axis, the straight line and
The joint of X-axis in first quartile is the subpoint of the X-axis in first quartile of point 204.Current level can be from Real-time Water
It is obtained in feelings table.
Then, according to the subpoint with point 204 in the X-axis of first quartile, on storage capacity-Na Yu ability relation line 202
Search the point 206 with point 204 in the X-axis of first quartile with same projection point.Subpoint of the point 206 in the Y-axis of fourth quadrant
Corresponding value is rain ability of currently receiving corresponding to reservoir.
Step 4: obtaining the precipitation of weather forecast, crosses with the rain ability of currently receiving in third quadrant；
Specifically, possession future weather forecast achievement is obtained according to weather forecast, including the grid directly from database
Numerical forecast achievement and weather forecast achievement from possession meteorological station, and then obtain the precipitation in the following predetermined period
208。
According to being parallel between X-axis where the straight line for being parallel to Y-axis where precipitation 208, and point 206, obtain
Joint 2010 of aforementioned two straight lines in fourth quadrant.
It is emphasized that the precipitation in predetermined period can be obtained from meteorogical phenomena database table according to the station yard of reservoir
It takes, such as can be obtained from meteorological following precipitation numerical value achievement or interactively enter in precipitation forecast achievement.
Step 5: judge that the joint currently received between rain ability and the precipitation is located in the third quadrant
Draw using origin as the left side of the angular bisector of starting point or right side；If being located at left side, need to carry out preparatory flood discharge to reservoir；
If being located at right side, do not need to carry out preparatory flood discharge to reservoir.
Judge that joint 2010 is located at the left side of the angular bisector 203 of third quadrant or right side needs if being located at left side
Preparatory flood discharge is carried out to reservoir；If being located at right side, do not need to carry out preparatory flood discharge to reservoir.
In practical applications, joint 2010 can be clicked through with red on interface as shown in Figure 2 by cell phone application
Row flashing display.
Using embodiment illustrated in fig. 1 of the present invention, according to building water level-storage capacity-Na Yu ability-weather forecast drop of component
Friendship of the rainfall in four axis, three phase coordinate system in four axis of water, three phase coordinate system, available current level and predetermined period
Then meeting point may determine that whether need to carry out preparatory flood discharge to reservoir, relative to existing skill according to the position of the joint
Blindness operation is carried out in art, improves the accuracy of reservoir capacity scheduling.
Finally, the embodiment of the present invention can load the embodiment of the present invention in cell phone application, it is pre- whether progress reservoir needs
The automatic calculating of first flood discharge reduces the management difficulty of the requirement and reservoir operation professional to operator, can be convenient use
The use at family.
Furthermore the present invention fully considers that small reservoir flood control standard is low, reservoir distribution is multi-point and wide-ranging, and administrative staff are most
The reality for belonging to non-specialized-technical personnel merges professional algorithm by common platform, in a manner of cell phone application, realizes simple adjust
Degree, is the reference means that reservoir safety is passed the flood period.It is emphasized that the embodiment of the present invention is only to water level in spillway elevation of weir crest
(and following) controls as characteristic level of water and predicts the following measure of passing the flood period for having and letting out in advance in advance under the conditions of precipitation, is design back
The supplement of scape lower storage reservoir safety.
On the basis of embodiment illustrated in fig. 1 of the present invention, embodiment illustrated in fig. 3 of the present invention additionally provides another for small
The simple dispatching method of type reservoir.
