Geographic spatial information application system and implement method thereof based on microkernel technology

Abstract

The invention discloses a geographic spatial information application system and an implement method thereof based on microkernel technology. The method creates a resource loading server by the microkernel technology. The method comprises the following steps that (1) the resource loading sever obtains a function service demand listing; (2) a resource loading supervisor confirms the function service demand listing and calls a function resolver to form a function module demand listing; (3) a listing counter of the resource loading supervisor checks resource allocation files, calls corresponding function modules and renews function module state labels; (4) a function combiner of the resource loading supervisor uniformly packages function serving modules as a function plug-in, wherein the function plug-in is used for responding calls of a client software, the function combiner generates function module labels, and the function labels and the function plug-in are returned to the client software together; (5) the client software calls the function plug-in. The method creates managing and automatic loading of atom granularity function modules and achieves efficient dispatch and ordering management of function resource, wherein the method bases on the microkernel technology.

Description

technical field [0001] The invention relates to the field of GIS, in particular to a micro-kernel technology-based geographic space information application system and an implementation method thereof. Background technique [0002] The concept of micro kernel (micro kernel) was first proposed by Richard Rashid. Although it was originally designed to build a microkernel operating system based on a message transfer mechanism, it was not for software architecture; however, in recent years, with the development of "component" and "layered" software systems, microkernel technology and construction The idea is gradually introduced into the software design framework to "decouple the relationship between components as much as possible". [0003] Applying microkernel, when running an application, you only need to load the selected system service into the system, and after modifying the service, you can test it online; there is no need to rebuild or start a new kernel, they It does n...
