Problems solved by technology

[0004] In the existing domestic software and hardware environment, due to the limited CPU performance of the GIS server, it takes too long for the GIS server to generate the pictures required by the front-end browser, which leads to the untimely display of road conditions deployed in the domestic software and hardware environment. And there is a phenomenon of Caton

Abstract

The invention provides a system for providing a real-time road condition service of a road. According to the system, a road link state changing continuously is stored into an internal storage unit of the system and is cut into map cutting pieces at different levels for caching. Therefore, a defect that the road condition can not be displayed timely in the prior art can be overcome and thus the requirement of real-time displaying of the road condition can be met; and the requirement of the GIS server performance is reduced.

Description

technical field [0001] The invention relates to the technical field of road condition monitoring, in particular to a system for providing real-time road condition services. Background technique [0002] In the prior art, the main method of displaying road conditions in real time on a GIS map is usually: the GIS server reads the road link state data from the GIS database according to the service request of the front-end browser, and generates the road link state data The corresponding request picture is returned to the front-end browser to display the requested real-time road conditions for the user. [0003] In the process of realizing the present invention, the inventor found that there are at least the following technical problems in the prior art: [0004] In the existing domestic software and hardware environment, due to the limited CPU performance of the GIS server, it takes too long for the GIS server to generate the pictures required by the front-end browser, which l...
