Through many years’ development, GIS (Geographic Information System) has made the huge progress, and utilized unceasingly in each professional fields along with the social application needs. Along with the economical unceasing development, the development of city is getting faster and faster, this brings new challenge to the fire department. In order to a more effective local constable protects national and people’s life and property security, sharpens the fire prevention quick reaction capability. It’s very important to construct the Fire alarm mobile platform location system.The design and implementation of GIS in Fire alarm mobile platform location system is one of the keys in the whole system. Close to the actual, full-featured GIS will provide a strong support decision-making function to the Fire alarm mobile platform location system. This paper has needs analysis on the GIS, designed the overall structure of the system, and the focus of this article set out on the road network generation and optimal path searching for two functional sub-modules of the detailed design.This paper introduces the characteristic of GIS data and the design of the main storage mode and logic structure of the Database of GIS, and described of the main types of data planning and data model of the database. Combination of the actual implementation of fire extinguishing system, according to the functions of organizing data layers, and gives the organizational structure of the main data and designed the special fire electronic map layers.Electronic map is the use of computer technology to store and access digital maps; it is a very important component of GIS system. In the GIS of fire, urban road network plays a very important role in the foundation of the shortest path, the fire power of the layout and the location on the map. In this paper, current techniques use images taken from the road network map of the image method is incomplete, high degree of comp- lexity, huge storage space, update the maintenance of red tape and other shortcomings, is proposed and implemented a platform based on GIS spatial databases of fire of the road network algorithm automatically generated. From the database through the extracted nodes and the road segment data, as well as traverse the various nodes connected to its line relationship between the generation of road networks, optimal path search algorithm for the design and implementation of a foundationThe shortest path problem is one of a fundamental problem in the process of the GIS in Fire alarm mobile platform location system, it occupies an important position in the whole GIS system. However, often the existing GIS platform is based on the electronic map to calculate the distance of the length of the shortest path, and neglect the practical problems such as traffic jams and urban road reconstruction, the reliability of hard to be guaranteed. In this paper, through in-depth analysis of GIS in Fire alarm mobile platform location system platform space algorithms and image recognition technology principle put forward a Dijkstra shortest path algorithm with the image recognition technology to solve the issue of the optimal path of thinking. Through the traffic monitoring system to obtain real-time picture of road traffic, and the use of image recognition technology to match the gray principle to Binarization image conversion. Through compared with the original path of right photos, under the picture to match the level of real-time sections for the given weight. GIS platform can be based on real-time dynamic information section of the right to calculate the value of a more reasonable and closer to the actual fire-fighting vehicle routes, fire alarm mobile positioning system more reliable.
