Description

Voice recognizing system and using method of navigation system connected real time traffic information}

The present invention relates to a voice recognition device of a navigation system associated with a real-time traffic information network and a method of using the same. More particularly, when a driver informs a navigation terminal of a destination by voice in a navigation device installed in a vehicle, The driver will be able to see the various routes from the current location to the destination informed by voice, and output the current traffic status by monitor or voice from the real-time traffic information network connected to satellite, internet or wireless communication network. The present invention relates to a method of using a voice of a navigation system associated with a real-time traffic information network for selecting a route.

Recently, various navigation systems using GPS are becoming more and more popular, and real-time traffic information is also provided in various ways. However, the current navigation system has a lot of difficulties in selecting a destination, a route search, etc. In addition, since the touch screen method of the monitor is mostly used, an unfamiliar person can not only use the device but also touch the touch screen accurately. If it is not made, the reality is that there are many cases of the destination selection error.

By connecting this problem with the voice recognition system using the memory circuit to the navigation and the real-time traffic information network, everyone will be able to use the navigation system completely and conveniently.

The present invention, in view of the problems of using the conventional navigation as described above, when all people use the navigation voice recognition and storage to the geographic information providing unit that can be used accurately and conveniently without going through the current complex process By linking departments, the names can be stored by voice for each region, and the corresponding region can be output to the navigation display unit by the destination command through the voice recognition unit. Its purpose is to make it a choice.

3: real-time traffic information server 11: voice recognition and storage

12: communication unit 13: path calculation unit

14: control unit 15: display unit

16: map storage unit 17: GPS

In order to achieve the above object, a voice recognition and storage unit capable of selecting a location using a voice command in addition to the current location selection or selection method using a touch screen, a selected location and a current location received by a GPS. It includes a route calculating section that finds a plurality of routes and calculates the estimated time required, a communication section for receiving a current traffic condition of each route from the outside, and a controller for outputting to a display section.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is an overall system configuration diagram, as shown in FIG. 1, a real-time traffic information server 3 providing real-time traffic information, a navigation system 1, and a communication network providing traffic status information to a navigation system from a real-time traffic information server. Server 2. Meanwhile, the navigation system receives a real-time traffic situation information from the voice recognition and storage unit 11 and the communication network server 2 that recognizes and stores the user's voice, and the communication unit 12 for transmitting information on the current location and destination of the vehicle. GPS 17 for determining the current position of the vehicle, and a route calculation unit 13 for calculating the time required for each driving route from the current position to the destination according to the current traffic position information and the vehicle current position and destination; And a controller 14 for selecting the shortest driving route according to the user's selection or the time required for each driving route and outputting the display unit 15 together with the map.

In addition, the GPS 17 detects the position of the vehicle by using the GPS satellites 4 and transmits radio waves to the GPS satellites 4, and the latitude and longitude of the current position of the vehicle transmitted from the GPS satellites 4 are also determined. Accurate coordinates are calculated and transferred to the path calculator 13.

In addition, the real-time traffic information server (3), which provides traffic status information to the communication network server (2), collects real-time traffic situation information in connection with road control systems such as CCTV and infrared cameras, which are generally installed on most roads. do. The real-time traffic information includes all factors that cause traffic congestion on the road, such as the number of vehicles driven by time and road, driving speed, road share of vehicles, accidents, and construction. The real-time traffic situation information thus identified is databased for each section or region and stored in the real-time traffic information server 13. The real-time traffic information is digitized and provided to the communication network server 2. The real-time traffic situation information is provided to the navigation system 1. At this time, the communication network of the communication network server 2 may be any communication means such as satellite, wireless, and the Internet.

2 shows an example of storing a user's voice in the voice recognition and storage unit 11 of the navigation system 1 for making a voice command. The user sets the navigation system 1 to the voice input mode 102. After selecting (103) a place name on the display screen 101, the selected place name is inputted by voice (104). In this order, the frequently operated destinations are repeatedly inputted (104 ^{1 to n)} . After the voice input operation is completed, the process switches to the input end 105.

On the other hand, Arabic numerals such as 1, 2, 3, 4-are stored as voice in one, two, three, four, etc. for voice command of the address, which is frequently used in selecting a place name. The most common sign of "-" is spoken as "back". To operate using the navigation system 1 having such a configuration, it is as shown in FIG.

Assuming that the destination is "100-22 Yeoksam-dong, Gangnam-gu, Seoul", when the current position of the car is displayed on the display screen 202 by the GPS (17) using the GPS (17) If the command is again, the corresponding destination location stored in the map storage unit 16 displays several paths 204 from the current location 202 indicated by the GPS 17 on the display screen to 100-22 Yeoksam-dong, Gangnam-gu, Seoul. do. At this time, the path numbers ①, ②, ③, etc. will be displayed for each path. When the route is displayed, the real-time traffic information server 3 requests the current real-time traffic information for the corresponding route through the communication unit 12 and the network server 2 (205). And the received and received data through the communication unit 12 of the navigation system 1 is comprehensively analyzed by the route calculation unit 13 to determine the current traffic conditions and the time required for each route, including the control unit 14 and the display unit 15. Is displayed on the display screen (206).

In the above process, when the driver grasps the current situation for each route, when the voice command 207 of the selected route number is performed, the selected route is displayed on the display screen (208) and driving starts using the selected route. (209). At this time, the processes from (206) to (209) are performed in the control unit and the display unit in the same manner as before the corresponding item. On the other hand, after the driver instructs the destination 203 and displays several routes to the destination on the display screen 204, the driver arbitrarily makes a route without requesting the current traffic conditions for each route to the real-time traffic information server 3. The vehicle may be selected (210) to drive.

As described above, the use of navigation equipment currently used by complicated procedures can easily drive a car to the navigation system with the user's voice recognition and storage system, and also automatically display real-time traffic as well as displaying a route along with a destination command. Connected with the information network, the optimal route can be selected and operated.
