APPARATUS FOR DISCRIMINATING ELEVATED WAY/SUBWAY USING 3-AXIS GEOMAGNETIC SENSOR AND CONTROL METHOD THEREOF

摘要

The present invention relates to the sky way/underground wetting systems and control system that use 3 axis chinaware sensors, receive receipts machine (100) especially with the 2nd GPS of GPS satellite coordinate and vision data; Figure case phase data and height change data. 3 axis ego sensors (200) of input; After digital camera position phase data and the input of height change data, the right corner data and joint number detected are according to the position phase cognitron (300) detected; Detect the sensor (400) in second of vehicle moving distance; Map datum is in store in the 2nd CD-ROM(500) (500); The current location of vehicle, when by 3 axle sensors (200), when having input peach angular data, metamessage three times has been used with the data of peachiness, after the current location of vehicle is highway or underpass, with be shown in the second Ma Yi companies (600) of current vehicle position are shown on the map datum of display and allow vehicle show current location second layer LCD labels (700) inside form, this invention is the height of vehicle due to detected variation, the 3 axis ego sensors exported using D as signal are used, when vehicle enters highway or underpass, detect the current location of vehicle, it is used correctly in data, when hardware is constituted A/D converters do not need using hardware, it is also reduced the effect of unit price.
