Embodiment Construction

[0021] Further description will be made below in conjunction with the accompanying drawings provided by the present invention:

[0022] First, the GPS signal receiving module includes an antenna part and an information collection part. The antenna is an external circularly polarized active antenna. The antenna can be fixed on the windshield according to the physical structure of the sightseeing car or bus in the scenic spot to ensure that the satellite Signal acquisition is not affected.

[0023] Second, according to the actual environment of the scenic spot, set the signal acquisition interval, for example: 1s, 2s, 3s.

[0024] Thirdly, according to the routes of the scenic spot, set the minimum distance value between the positioning information and the visiting route, for example: 10m, 15m, 20m. Data filtering ensures that real-time positioning information does not deviate too much from the vehicle's driving route.

[0025] Fourth, according to the explanation point inform...

Abstract

The invention relates to a method for achieving a vehicle navigation system with a direction intelligent identification function, firstly the information of longitude and latitude positions is obtained through a global position system (GPS) module, position signals are collected and are filtered according to a fixed time interval, and the information of the longitude and latitude positions is kept in an error range of a navigation route. If the information of the longitude and latitude positions enters a preset position range of a system, a direction intelligent identification module judges the forward direction of a vehicle system to drive a navigation module to work after being processed through a matching algorithm, thereby supplying different navigation services. The method for achieving the vehicle navigation system with the direction intelligent identification function can achieve to supply different navigation servers for tourists in different back and forth direction of the navigation route of the vehicle system, and enables the system to be more humanized and intelligent.

Description

technical field [0001] The invention relates to a method for realizing a vehicle-mounted navigation system with a direction intelligent recognition function, which belongs to the field of vehicle-mounted intelligent navigation and can be widely used in tourist attractions. Background technique [0002] With the development of society and the improvement of navigation technology, more and more car navigation systems based on GPS positioning technology are used in various tourist attractions to provide all-round services for tourists who come to visit. Due to the limitations of the scenic spots on the tour route and the limited operating time of vehicles, it is difficult to provide comprehensive information services to tourists on the same direction of the tour route. There are needs and expectations for providing different guided tour services in different directions. Contents of the invention [0003] In view of the above problems, the present invention provides a vehicle...
