Open source map-based distributed GIS state monitoring system

Abstract

The invention discloses an open source map-based distributed GIS state monitoring system, and solves the problem that position information of a monitoring point free of surveying and mapping data cannot be determined. According to the key points of the technical scheme, a map display layer comprises a map display module used for displaying a current map region; and a business processing layer is used for inputting address information of each monitoring point, performing coordinate mapping on the address information in an inverse coordinate deduction mode to determine a coordinate position, and performing display in the map display module. According to the open source map-based distributed GIS state monitoring system, the inverse coordinate deduction is that address matching is performed in a geocoding manner, conversion from known address description to corresponding longitude and latitude coordinates is performed, and point coordinates corresponding to the address are queried, so that address-to-coordinate mapping is realized; and the longitude and latitude coordinates of each monitoring point can be obtained without entrusting a surveying and mapping department to perform data surveying and mapping, so that the manpower and material resources are saved and the position information of each monitoring point can be accurately obtained.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a distributed GIS state monitoring system based on an open source map. Background technique [0002] In the water industry, GIS applications mainly include two aspects: [0003] (1) Pipe network monitoring and pipe network simulation, using professional GIS maps, such as ArcGIS, requires basic product authorization and services provided by the GIS platform provider. [0004] (2) Use open source geographic information systems, such as various electronic maps, to display all distributed monitoring points, in the form of overview maps, with low investment costs. [0005] The application of GIS for pipe network monitoring has been applied in major water supply companies as early as the 1980s, and the technology is quite mature. There is a characteristic for each jurisdiction under a water group, pumping stations scattered throughout the city, pipeline inspection points, key equipment status, ...

AI Technical Summary

Problems solved by technology

[0006] Existing pipeline network monitoring GIS applications need to accurately display the actual monitoring object information in the open source map. Since each enterprise only displays a small number of monitoring points, if the surveying and mapping department is entrusted to conduct surveying and mapping to obtain the latitude and longitude coordinates of each monitoring point, it is easy to lose a lot of resources. Manpower and material resources, but the monitoring points without surveying and mapping data cannot determine their accurate location information, so there is still room for improvement
