Description
One, technical field,
The utility model relates to a kind of multimedia player that is used for tour description and direction, relates in particular to a kind of multimedia tour description and direction terminating machine of realizing tour description and direction by GPS location and RFID electronic tag location.
Two, background technology
1, GPS location and navigational system introduction and application trend
At present, sell on the market multiple gps satellite navigational system is arranged, this class navigational system is mainly used in the carriage way indication of vehicle, multimedia modes such as figure indication and auditory tone cues are adopted in navigation, owing to GPS because of covering and reason such as multipath, can't be in indoor positioning, and bearing accuracy is limited (wherein, the perpendicular positioning precision is poorer), therefore, the GPS navigation terminal is mainly towards vehicle, boats and ships and open-air scientific investigation.
Along with GPS location and navigational system in continuous development, nowadays the GPS technology is stepped into pedestrian's application away from the orthodox car application just gradually.Need at this variation, the GPS positioning system is needed badly to make significantly and is improved, and pure GPS location technology can't satisfy user demand that the pedestrian uses and consumer's expectation, must be in conjunction with other technologies, and as inertial sensor etc.And be the important trend of future development towards the GPS pedestrian of general marketplace location and navigational system.
2, the deficiency of GPS location technology and improvement project
The main deficiency of GPS location technology is can't be in indoor positioning with reasons such as multipaths because of covering, and covers under the situation non-, and bearing accuracy is limited, and the horizontal location precision is 20 meters～30 meters, and theoretical value is 2.93 meters～29 meters.According to the GPS Positioning Principle, because earth interior does not have satellite, therefore, the perpendicular positioning precision is on the low side, and the perpendicular positioning precision is 45～100 meters, if adopt sensor auxiliary, can be improved as 5～10 meters, even the perpendicular positioning precision after improving for building or location, hill path, obviously is not enough.
GPS obtains the location needs the time, can not start GPS at any time, just obtains locating information at once, under the good situation of all conditions, starts acquisition time less than 1 minute, is generally 2～3 minutes; If gps signal is bad, obtaining positioning time will be very long, cause using the GPS location.Therefore, the continuous positioning performance of GPS may reduce because of covering.
In automobile GPS location and navigational system, even the location is inaccurate, but can calculate principle by the deployed position coordinate, go out current location, speed and direction from a last position calculation and still be relatively easy to; In addition, map data base and user also help further to confirm the position to the understanding of road, so the user can infer the travel route that automobile quite assertorically.On the contrary, the pedestrian but is changeful, is difficult to predict.People usually like taking a shortcut, passing in and out each buildings, stop, set out, and swerve again, but they may more need to know accurate more positional information than the driver.For example, not only need to know and also will further know beyond the street at any bar the street.The onboard navigation system per second can be finished data acquisition for several times, and a data can only be collected at a street corner by the pedestrian navigation system of crested often, and this makes the precision of each GPS position and reliability even more important in using than automobile.

The method of RFID positioning label assistant GPS location is as follows:
Be difficult to locate the point of interest that maybe can't locate at GPS and dispose the RFID positioning label, point of interest can also can not only can be deployed in the street indoor out of doors, also can be deployed in buildings, shop, park, tower booth pavilion etc. and locate.
During use, the RFID reader is process on the RFID positioning label, and terminal just can be obtained the geo-localisation information in the RFID positioning label, and the locating information of acquisition is given user's positioning service by position service system.The RFID positioning label not only can be used for the pedestrian, also can be used for vehicle, generally is used for the pedestrian.
Organically do not get up GPS location and RFID positioning label positioning combination in RFID positioning label assistant GPS location, the locator data in the RFID positioning label is shared with GPS, and two systems do not have combination effectively parallel in the time of in fact.
4, the technical scheme of present tour description and direction
