Title: MAP NAVIGATION SYSTEM FOR USE IN LARGE BUILDING
Abstract:
The application relates to the technical field of indoor navigation. Disclosed is a map navigation system for use in a large building capable of providing indoor navigation for a user carrying a digital terminal. The navigation system comprises: a control router for configuring a wireless network; and multiple access points distributed in respective rooms in a large building. The control router calculates relative locations according to delay in data transfer between the digital terminal accessing the wireless network thereof and the respective access points, and transmits location information to the digital terminal. The digital terminal is built in a piece of electronic map software. The electronic map software displays, in real time, navigation information according to the location information. The map navigation system for use in a large building of the invention can automatically track a location of a digital terminal accessing a wireless network, and transmit signals to provide the digital terminal with location information. The electronic map software built in the digital terminal uses location information to provide navigation to a user, such that the user can intuitively ascertain his/her location and find a target location.
