Campus positioning method based on LBS platform and realization system thereof

Abstract

The invention discloses a campus positioning system based on an LBS (Local Based Service) platform, which integrates Wi-Fi (Wireless Fidelity), GPRS (General Packet Radio Service) technology and Internet, mobile communication, a GIS (Geographic Information System) and other networks, and achieves the functions of terminal positioning, map inquiry, navigation, tracking management, short-message notification and the like by utilizing a GPS (Global Positioning System) chip cell phone or a PDA (Personal Digital Assistant) client side. The system provides various information services related to the positions of schools for students, teachers and visitors, realizes personnel and building position management, achieves yellow-page inquiry management that flexible and various bidirectional spatial inquiry of both graphical information and attribute information in the Web GIS system can be carried out, realizes group management that actions of a user within an effective period of time are record to form space and time combined data to design a user and group essential information database for data storage, and provides normative expansion interfaces to achieve efficient communication and cooperation among interiors of teaching and research sections, all the departments and all the personnel. The system has the advantages of high cost and precision, strong cooperative handling capability and the like.

Description

Technical field [0001] The present invention relates to a perceptual computing integration system, in particular to a campus LBS (Location Based Service) platform based on indoor and outdoor positioning, which can provide teachers, students and visitors with various location-related information services such as tour guides and navigation methods and Its realization system. Background technique [0002] With the development of campus informatization construction, the concept of "digital campus" has also appeared. The so-called "digital campus" refers to a digital and virtual campus, which is a concrete manifestation of the microscopic representation of the "digital earth" in the campus area. "Digital campus" has the characteristics and functions of "digital city". It displays various spaces and attributes of the campus by enabling graphics and image digital information layers to provide users with various campus information query, retrieval, and necessary spatial analysis and stat...

AI Technical Summary

Problems solved by technology

When there are buildings blocking or indoors, the positioning accuracy and availability are greatly reduced, the power consumption of the positioning terminal is relatively large, and the power supply requirements are high

Although the positioning technology of the mobile network is currently widely used, there is a problem of poor positioning accuracy. Among them, the GSM communication network is used to realize the communication between the mobile terminal and the information service center. The information service center is the core of the positioning service system and is responsible for communicating with the mobile terminal. Information interaction and network interconnection of each sub-center, complete the classification, recording and forwarding of various information and the flow of business information between each sub-center, and monitor the entire network, which cannot meet the application requirements of some high-precision positioning
