Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
A method for determining a section water level, as shown in fig. 1, comprising the steps of:
step S101, dividing a water area into a plurality of sections, and taking the section of each section as a calculation reference.
The water area refers to rivers, lakes, channels, reservoirs and the like, when the water level of the rivers is determined, if branches and branch branches occur, the water level of one branch is taken to determine the water level of a river mouth, and the river mouth is a water area terminal point, namely the position where the water area is injected into oceans, lakes or other water areas.
In this embodiment, the cross-section is a longitudinal cross-section of the water area, i.e. a cross-section along the centre line of the water area. It can be understood that each water level condition of the water area can be influenced by different environmental factors, and in order to accurately obtain the water level data, the water area should be divided, and an area with similar water level changes is taken as a section. For example, different terrains have different influences on the water level change of the water area, so the water area can be divided into a plurality of sections according to the terrains information of the water area. Of course, a water area dividing method commonly used in the art may also be adopted, and will not be described herein.
And S102, receiving the positions and the water levels of at least two monitoring points transmitted by the monitoring device on the section, and analyzing the positions and the water levels of the at least two monitoring points to obtain the position-water level relation of the section.
A plurality of monitoring devices are generally arranged on the section of each section, and each monitoring device corresponds to one monitoring point. The position information of the monitoring point is mainly longitude and latitude information. In practical use, if the environment of a certain section is very severe and too many detection devices cannot be arranged, the water level-position relationship can be obtained only by two monitoring points, and the obtained position-water level relationship is a straight line. In some embodiments, more monitoring point position and water level information may be used to describe the position-water level relationship of the section more accurately, such as the position-water level relationship of the section obtained by analyzing the positions and water levels of at least three monitoring points. The position-water level relation of the section cross section may be a straight line or a curved line.
The method for determining the position-water level relationship of the cross section by the water levels and positions of the two monitoring points in step S102 will be described in detail with reference to fig. 3. As shown in FIG. 3, the upstream reference point a and its water level H are knownaDownstream reference point b and level H thereofbThe length of the center line of the river channel between the two monitoring points a and b is L, and the distance from a certain point x to the downstream reference point b is L1(L1However, it may be positive or negative, and L is a point upstream of the reference point b when the point x is a point1Is a positive number; when point x is a point downstream of reference point b, L1Negative), the slope k of the water level change from upstream to downstream of the two monitoring points a and b is (H)a-Hb) L, therefore the water level H at point xx＝Hb+k*L1This is the position-level relationship of the cross section. According to the above method, the slope of each sectional plane can be obtained (for example, the slope of the sectional plane in the first section is denoted as k)1And the slope of the second section is denoted as k2By analogy, the slope of the n-th section is kn) Thereby obtaining the position-water level relation of the section of each section.
The method for determining the position-water level relationship of the section through the water levels and the positions of at least three monitoring points in step S102 is specifically described with reference to fig. 4. As shown in fig. 4, a coordinate system is established with the position as abscissa and the water level as ordinate, the coordinate points corresponding to each monitoring point are drawn in the coordinate system according to the positions and water levels of the 3 monitoring points, and each coordinate point is connected in sequence by a smooth line to obtain an approximate straight line (as shown in fig. 4(a)) or a curve (as shown in fig. 4(b)), that is, the position-water level relationship of the cross section. Of course, the more the number of the monitoring points is, the higher the accuracy of the obtained straight line or curve is, the more accurate the position-water level relation of the section is, and the more accurate basis is provided for determining the water levels of other positions on the section.
And step S103, substituting the position of any point on the section into the position-water level relation to determine the water level of the point.
Next, how to determine the water level at any point on the cross section will be described with reference to the position-water level relationship Hx + k + L1 obtained in step S102. And taking a point c on the section, wherein the river course distance between the point c and the downstream reference point b is Lc, and substituting Lc into the position-water level relation to obtain the water level Hc of the point c as Hb + k.
Due to the requirement of flood control, the maximum flood discharge water levels at different positions are different, so that the water levels at all positions of the whole water area are monitored. According to the method for determining the water level of the section, the position-water level relation of the section can be determined through the water level data of at least two monitoring points on a certain section, and if the water level data of at least two monitoring points on each section is obtained, the position-water level relation of all sections can be obtained, so that the water level of all positions on a water area can be determined.
The invention discloses a method for determining the water level of a section, which divides a water area into a plurality of sections, each section takes the section as a calculation reference, receives the positions and the water levels of at least two monitoring points transmitted by a monitoring device on each section, analyzes the positions and the water levels of the at least two monitoring points to obtain the position-water level relation of the section, and substitutes the position of any point on the section into the position-water level relation of the section to calculate the water level of the point. According to the method, manual work or monitoring devices are not needed to be added, water level data of all positions on a certain section can be calculated only through water level data of at least two monitoring points on the section, and the water levels of all the sections are combined to form the water level of the whole water area. The method has the advantages of efficiently, accurately and safely measuring the water level of each position, having full data volume and providing reliable basis for formulating the plan and related schemes of flood control work.
Example two
In other embodiments, a situation that water level data of a certain monitoring point is missing or water level at a future time needs to be predicted may occur, and if weather has no abnormal change, the water level change of a certain monitoring point along with time should have certain similarity, so this embodiment proposes a method for determining a section water level.
Specifically, as shown in fig. 2, a method for determining a section water level includes the following steps:
in step S201, a water area is divided into a plurality of sections, and each section takes its cross section as a calculation reference.
The water area refers to rivers, lakes, channels, reservoirs and the like, when the water level of the rivers is determined, if branches and branch branches occur, the water level of one branch is taken to determine the water level of a river mouth, and the river mouth is a water area terminal point, namely the position where the water area is injected into oceans, lakes or other water areas.
In this embodiment, the cross-section is a longitudinal cross-section of the water area, i.e. a cross-section along the centre line of the water area. It can be understood that each water level condition of the water area can be influenced by different environmental factors, and in order to accurately obtain the water level data, the water area should be divided, and an area with similar water level changes is taken as a section. For example, different terrains have different influences on the water level change of the water area, so the water area can be divided into a plurality of sections according to the terrains information of the water area. Of course, a water area dividing method commonly used in the art may also be adopted, and will not be described herein.
Step S202, receiving the positions and the water levels of at least two monitoring points transmitted by the monitoring device on the section, and analyzing the positions and the water levels of the at least two monitoring points to obtain the position-water level relation of the section.
A plurality of monitoring devices are generally arranged on the section of each section, and each monitoring device corresponds to one monitoring point. The position information of the monitoring point is mainly longitude and latitude information. In practical use, if the environment of a certain section is very severe and too many detection devices cannot be arranged, the water level-position relationship can be obtained only by two monitoring points, and the obtained position-water level relationship is a straight line. In some embodiments, more monitoring point position and water level information may be used to describe the position-water level relationship of the section more accurately, such as the position-water level relationship of the section obtained by analyzing the positions and water levels of at least three monitoring points. The position-water level relation of the section cross section may be a straight line or a curved line.
Step S203, the position of any point on the section is substituted into the position-water level relation, and the water level of the point can be determined.
Step S204, obtaining the water levels of at least two moments of a certain monitoring point through the position-water level relations at different moments, and analyzing the water levels of at least two moments to obtain the time-water level relation.
And S205, substituting the time of any moment of the monitoring point into the time-water level relation, and calculating to obtain the section water level of the moment of the monitoring point.
The method for determining the time-water level relationship of a monitoring point through the water levels of the monitoring point at least two times is specifically described below with reference to fig. 5. As shown in fig. 5, a coordinate system is established with time as abscissa and water level as ordinate, the coordinate point corresponding to each time is plotted in the coordinate system according to the time and water level of 2 times of a certain monitoring point, and each coordinate point is connected in sequence by a smooth line to obtain an approximate straight line (as shown in fig. 5(a)) or a curve (as shown in fig. 5(b)), namely, the time-water level relationship of the monitoring point. Of course, the more the number of the moments, the higher the accuracy of the obtained straight line or curve, the more accurate the time-water level relation of the monitoring point, and the more accurate basis is provided for determining the water levels of the monitoring point at other moments.
According to the method, the time-water level relation is obtained through water level analysis of at least two moments of a certain monitoring point, the time of any moment of the monitoring point is substituted into the time-water level relation, the section water level of the monitoring point at the moment can be calculated, the water level of the monitoring point at the moment is not required to be calculated after other monitoring points monitor the water level of the moment, water level data of future time can be predicted or missing water level data can be determined in advance, and guiding effects are achieved in water level research and flood control work.
