Problems solved by technology

[0003] Wireless routers can form WiFi signal nodes, but wireless routers cover a large area, especially in garages and other locations, and can only vaguely judge the location of a certain parking space. If you want to achieve more accurate positioning, you need to use wireless routers intensively. This will greatly increase the investment of equipment and cause the waste of the wireless network provided by the wireless router

Embodiment Construction

[0018] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] refer to figure 1 , figure 1 It is a block diagram of Embodiment 1 of the positioning system of the present invention, the positioning system includes a WiFi signal node 1 and a location server 2 .

[0020] Wherein, the WiFi signal node 1 includes a wireless router 11 and a wireless probe 12, and the wireless router 11 and the wireless probe 12 are both arranged in places where positioning is required, such as an underground parking lot, a certain floor of a building, and the like. The wireless router 11 can be used as a WiFi signal node, and can also be used as an access point of a wireless local area network, and one or more wireless routers 11 can be set as required. The wireless probe 12 is only used as a WiFi signal node. The wireless probe 12 can send out a wireless signal with its identification inform...

Abstract

The invention discloses a positioning system. The positioning system comprises a WiFi signal node and a position server. The WiFi signal node comprises at least one wireless router with unique identification information, and multiple wireless probes. The position server comprises an electronic map database for marking the distribution position of the WiFi signal node, and a position judgment module for positioning according to the WiFi signal node. According to the invention, the fuzzy range of the current position mode can be reduced; quite precise positioning is provided; investment cost meeting positioning requirements is quite low; the positioning system is suitable for indoor positioning navigation; by combining satellite positioning, seamless switching of the positioning modes is achieved; a problem of lack of positioning signals caused by the single navigation mode is avoided; positioning accuracy of a navigation system is improved; and better navigation experience is provided for users.

Description

technical field [0001] The invention belongs to the field of positioning and navigation, and in particular relates to a positioning system based on GPS, a wireless router and a wireless probe. Background technique [0002] At present, cars have become a relatively common means of transportation. People often drive cars to destinations, some of which are unfamiliar places. Usually, people use satellite positioning system for navigation to reach their destination smoothly, but some places such as tunnels and underground spaces will cause great interference to satellite positioning, and the current position cannot be confirmed, thus losing the route to the destination, which is difficult for drivers. cause trouble. With the development of communication technology, more and more WiFi signal nodes are placed beside the road, especially in underground spaces and tunnels. Since WiFi signal nodes have unique MAC addresses, it is possible to locate and navigate based on WiFi signal ...
