Problems solved by technology

However, it is usually limited to the monitoring of a small number of points, and the limited monitoring data cannot know the operating status of the system well, and provide decision-making information for the operation optimization and control of the overall system of the drainage network.
This has resulted in a passive situation in which the current drainage system "only monitors but does not ...

Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing

[0026] like figure 1 Shown, the concrete implementation steps of the inventive method are:

[0027] (1) Command and decision-making personnel enter the back-end management platform of the system to check the regional water flow situation. After entering the url address in the browser, the water flow status information in the map and table with Beijing as the center and the zoom level at the maximum level is displayed.

[0028] (2) Click the "City Switch" button to select the city to view. If you don't switch, the water flow situation information of Beijing will still be displayed. For city switching, use the CityList open source library provided by Baidu Maps for city business districts and administrative districts. In the page, add a city click event and a city change event to the CityList object instance, that is, to realize the city switching.

[0029] (3) Click "Curre...

Abstract

The invention discloses a Baidu map based water flow situation display method. According to the method, firstly, access is performed by using a Web browser on a system back-end management platform; a 'city switching' button is set to rapidly replace city information corresponding to a current map view; secondly, two modes for displaying a water flow situation range are set; then, the number of water flow situation records within a certain convergence zone is displayed at the current level in a map zooming mode; finally, specific situation information and summary information of all recent water flow situation records within the current zone are displayed on a page, and water flow situation values reaching or exceeding the preset danger level are marked with red in a table and are marked with different colors on a map. The Baidu map based water flow situation display method can obtain the given range in a real-time water flow situation information table and the water flow situation information within a given time and uses round markers corresponding to colors to perform visual display on pages according to situation level values.

Description

technical field [0001] The invention belongs to the fields of geography and hydrology, and in particular relates to a method for displaying water flow situation based on Baidu map. Background technique [0002] With the acceleration of urban construction and the continuous increase of construction scale, urban rainstorm and flood disasters are becoming more and more frequent, causing heavy human and economic losses. The formation of urban waterlogging is closely related to the drainage status of urban drainage systems. Therefore, strengthening the construction of drainage pipe networks has become especially important. [0003] The urban drainage pipe network system is an important urban infrastructure. Its function is to collect and transport urban sewage and runoff generated by the city and snowmelt in a timely manner. It has the dual functions of protecting the environment and reducing the burden on the city. With the acceleration of urbanization in our country, the const...
