Embodiment Construction

[0015] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with examples. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0016] figure 1 It is a system schematic diagram of a preferred embodiment of the present invention. The system includes a server 1 and a user 2, which are separated in space. Among them, the number of users 2 is relatively large, that is, one server can serve multiple users at the same time, and the implementation of the user can be a vehicle-mounted A navigation terminal or other portable mobile positioning or navigation equipment can also be a mobile phone or other mobile equipment with navigation functions.

[0017] like figure 1 As shown, the server 1 includes a server processor 11 for analyzing and processing data infor...

Abstract

The invention relates to a real-time map navigation system and method. The real-time map navigation system comprises a service end (1) and a user end (2), wherein the service end (1) comprises a service-end processor (11), as well as a user database (12), a map module (13) and a communication port (14), which are respectively communicated and connected with the service-end processor (11), and the map module (13) further comprises a map update module (131) and a map storage module (132); the user end (2) comprises a central processing unit (21), as well as a positioning module (22), a storage device (23), a communication module (24), an input module (25) and a display module (26), which are respectively communicated and connected with the central processing unit (21); and the positioning module (22) is communicated and connected with the communication port (24) through a wireless communication network. According to the real-time map navigation system and method, only a map related to a navigation route is sent to the user end through the recombination of map elements of a real-time map, so that occupied bandwidth is reduced and navigation efficiency and user experience are improved.

Description

technical field [0001] The present invention relates to navigation technology, more specifically, to a real-time map navigation system and method. Background technique [0002] Today's urban planning is changing with each passing day, and information such as roads, buildings, and road conditions in the map is constantly changing. The accuracy of the map in the existing car navigation can no longer meet the needs of users. Due to the insufficient frequency of map updates, users are relying on it for navigation. Mistakes often occur during the process, causing inconvenience to users and even causing losses. [0003] On the other hand, due to the frequent update of the map, the user has to spend a large amount of bandwidth on updating the map, which consumes time and money, and affects the experience of navigation. Contents of the invention [0004] The purpose of the present invention is to provide a real-time map navigation device and method to provide users with a real-ti...
