Problems solved by technology
[0003] Existing technologies for simulating water level changes in river and reservoir dam sections only stay in static simulation and each water level value corresponds to a chart. The disadvantages are: 1. The display of water level changes is not vivid enough and cannot dynamically display the water level of the section Real-time changes; 2. It is difficult to develop and requires solid program development capabilities, which is not easy to promote technology; 3. It is not conducive to integration on web pages

Embodiment Construction
[0033] Specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0034] Such as figure 1 Shown is the principle diagram of the present invention, and the present invention is based on the Flex Area Chart chart technology. The superposition of two AreaSeries is used to simulate the water body and the river bed. The water level elevation data and the river bed elevation data are constructed into a coordinate sequence. For example, the elevations of 5 typical points on a river section are 102, 101, 100, 101.5, and 102.2 respectively, then These 5 points can be constructed into the following coordinate sequence: (1,102), (2,101), (3,100), (4,101.5), (5,102.2), if the water level elevation at a certain moment is 101.3, then the coordinates of the water level data construction The sequence is: (1,101.3), (2,101.3), (3,101.3), (4,101.3), (5,101.3), and finally passed in in XML format.

The invention provides a method and a system for simulating a river cross section dynamically, which are based on FlexAreaChart. The method comprises the following steps: constructing coordinate sequences for river bed typical point elevation data and water level elevation data; respectively assigning the constructed coordinate sequences to two AreaSeries of the AreaChart; and assigning values to sequences of water level data within a section of time by using a timer function of a FlexChart, so as to dynamically display the water level in a river cross section. The method and the system provided by the invention have the advantages as follows: dynamic simulation requirements on river cross sections, reservoir dams and water body water level variation situations in a water conservancy information system are satisfied; simulation effect pictures are vivid in presentation and better in interactivity.
Description
technical field [0001] The invention belongs to the field of information technology, in particular to a dynamic simulation method for a river section. The method is a dynamic simulation method for a river section based on Flex Area Chart. technical background [0002] my country's water conservancy information construction is in an important period of development. Various water resource management systems, flood control command systems, and monitoring and early warning systems are being built in large quantities. Managers urgently need various information displays that can be visually visualized. A Flex-based Area Chart's river section simulation method can simulate rivers, reservoir dam sections and their water level changes, allowing users to more intuitively understand the historical water level data and forecast water level of river or reservoir dam sections. [0003] Existing technologies for simulating water level changes in river and reservoir dam sections only stay in...
