Hereinafter, the present invention will be described in detail by explaining preferred embodiments of the present invention with reference to the accompanying drawings. Like reference numerals in the drawings denote like elements.

1 is a block diagram of an apparatus for providing location information of a vehicle according to an embodiment of the present invention. The location information providing apparatus 101 is installed in a vehicle to provide location information of the vehicle to a vehicle user. Referring to FIG. 1, the location information providing apparatus 101 includes a microphone 141, a voice recognition unit 131, a GPS (Global Positioning System) receiver 111, a speaker 171, a liquid crystal display 151, and a controller ( 121 and a light emitting diode (LED) 161.

The voice recognition unit 131 processes and stores voice data output through the microphone 141. Automatic Speech Recognition is a tool that acts as a medium for the machine to recognize human speech. The voice recognition unit 131 analyzes the voice of the car user and recognizes or understands it, and uses a human voice having a specific frequency due to the shape of the mouth and the position of the tongue according to the pronunciation of the car user. After converting to and storing the voice signal of the car user to extract the various characteristics of the voice signal.

The GPS receiver 111 receives satellite data transmitted from a GPS satellite to calculate a location and speed of the vehicle, for example, a vehicle, and an area in which the vehicle is equipped with a surveillance camera for tracking a specific coordinate setting area, for example, the speed of the vehicle, When the traffic accident area, severe fog, a lot of falling rocks, the danger zone when speeding on the road to notify the control unit 121. An antenna 113 is connected to the GPS receiver 111, and the antenna 113 tracks GPS satellite signals using an algorithm built in the GPS receiver 111, and when only one satellite signal is tracked, relative positions of other satellites from that satellite are detected. Information on can be tracked so that all visible satellite signals can be tracked in a short time. The position and speed information obtained by receiving GPS satellite signals is basically used for navigation and tracking of a vehicle.

The GPS satellite continuously transmits a navigation message necessary for position calculation to the GPS receiver 111 through a carrier wave. The carrier wave is accurately adjusted to two frequencies L1 (1575.42 [MHz]) and L2 (1227.6 [MHz]) of the L band and transmitted to the GPS receiver 111. Each GPS satellite is arranged on four circular orbits, each with a 55-degree tilt angle. GPS satellites are located 26567.5 [km] from the Earth's center and have a period of about 12 hours. This GPS satellite arrangement is specially designed so that at least four satellites are always visible throughout the earth to calculate the three-dimensional position and receiver clock error of the GPS receiver 111. The satellite data transmitted from each GPS satellite includes a PRNudo Random Noise code (PRN code) specially designed for each satellite number. That is, since GPS satellite data is transmitted to the GPS receiver 111 in Code Division Multiple Access (CDMA), the GPS receiver 111 may clearly receive navigation data corresponding to each satellite.

The controller 121 stores a map of a specific area, for example, a map of downtown Seoul, and when the car user designates a part of the area, for example, Seocho-dong, through the microphone 141, the controller 121 displays the map of the Seocho-dong. ), And also the specific coordinate setting area of the Seocho-dong, for example, the area where the surveillance camera is installed to monitor the speed of the car, the traffic accident area, the fog area, the rocky area, the dangerous area when overspeed on the road And so on. When the controller 121 receives the information indicating that the vehicle is approaching the specific coordinate setting area from the GPS receiver 111, the controller 121 alerts the vehicle user through the speaker 171.
