Other objects, specific advantages and novel features of the present invention will become more apparent from the following detailed description and the preferred embodiments associated with the accompanying drawings.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the taxi dispatch system using a telephone according to the present invention.

1 is a system configuration diagram of a taxi dispatch system using a mobile phone 10 as a first embodiment of the present invention. As shown in Figure 1, the system of the present invention is approximately mobile phone 10, base station 20, communication company server 32, voice recognition server 50, voice recording server 55, dispatch server 60 And an operator and a taxi 70.

The mobile phone 10 may be any one such as a CDMA cellular phone, a PCS, a PDA, and the like, as long as the customer can carry or use a voice call.

The base station 20 is a relay base station for connecting the mobile phone 10 and the communication company server 32. The base station 20 is installed in a certain way throughout the country.

The communication company server 32 is a system that manages telephone connection and various communication operations.

The voice recognition server 50 is a server that receives the voice spoken by the customer and converts it into text data. Detailed internal configuration and operation thereof will be described with reference to FIG. 5.

The voice recording server 55 is a server that records the voice of the customer when the voice recognition server 50 fails to recognize the voice of the customer, and plays it in sequence at the operator.

The dispatch server 60 transmits a dispatch command to a plurality of taxis in a corresponding region using text data recognized by the voice recognition server 50, receives a dispatch request message from a specific taxi, and confirms the dispatch. It stores and manages various boarding information and current taxi location data.

As a specific dispatch method of the dispatch server 60, CBS method and TCP / IP method are used.

The CBS (Cell Broadcasting System) method is a transmission method that divides one or several mobile communication network base stations into a unit of a concept of zone and enables message broadcasting to all CBS terminals in each zone. Such a zone may be designated, enlarged, and reduced, as well as a unit zone may be configured by one or several base stations and administrative regions. In addition, when using the CBS scheme, a maximum of 812 bytes can be transmitted to all terminals in the same zone. That is, when a customer requests a taxi allocation, when the user broadcasts in the zone closest to the client, the vehicle receives the distribution through the CBS terminal mounted in the taxi.

The TCP / IP method (also known as wireless Internet method) is a method of transmitting a message to the center by the TCP / IP protocol when a taxi commanded by the CBS method wants to allocate the car. In case of using TCP / IP method, it is cheaper than the existing SMS method (up to 6.3 won per 0.5 KB, up to 1.3 won), and can be actively used due to low loss of message or delay of transmission.

Taxi 70 has a built-in CBS terminal is capable of two-way data communication with the dispatch server (60). In addition, when using the tacometa (fare meter) that is operated when the customer gets on and off, the customer getting on and off information and current position data is transmitted to the dispatch server 60.

2 is a system configuration diagram of a taxi dispatch system using a landline telephone as a second embodiment of the present invention. As shown in Fig. 2, the difference between the second embodiment and the first embodiment is that instead of the mobile phone 10, a landline telephone 12 provided in a home or office is used.

4 is a table configuration diagram of a database installed in the dispatch server 60 of FIGS. As shown in FIG. 4, a second main region coordinate DB 62, a boarding information DB 64, a location information DB 66, and a driving information DB 68 are implemented under the dispatch server 60. .

The second main region coordinate DB 62 stores position (address) or coordinate data of a main region (dong, large building, public institution, station, playground, hospital, airport, etc.) for each administrative region.

The boarding information DB 64 stores data of a taxi serial number (for example, a vehicle number), a boarding date and time, a boarding position and a getting off position, a moving distance, an incurred fare, a surcharge, a driver's name, and the like.

The location information DB 66 stores current location information of each taxi. In addition, the driving information DB 68 stores information about the mileage, the year, various troubleshooting information, the model, the driver's name, and the like of each taxi.

Hereinafter, an operation method of a taxi dispatch system having the above configuration will be described. First, FIG. 3 is a flowchart illustrating a schematic distributing method of a taxi distributing system according to the present invention. As shown in Figure 3, the customer calls a specific phone number (S10).

Next, the voice recognition server 50 receives a taxi dispatch request from the customer through the telephone company server 32 (S10). At this time, in the case of the mobile phone 10, it is received through the relay base station 20 and the communication company server 32, and in the case of the landline phone 12, it is received through the telephone company (not shown) and the communication company server (32).

Next, the voice recognition server 50 recognizes the location information of the customer from the voice information of the customer (S20). A detailed method relating to recognition will be described later with reference to FIG. 5.

Then, if the recognized location information is confirmed by the customer (S30), and transmits the recognized location data to the dispatch server (60) (S40). For confirmation, the recognized location information can be displayed to the customer and pressed to confirm whether the button is correct or incorrect.

Then, the dispatch server 60 transmits a wireless dispatch command to the taxis in the area to which the received location data belongs (S50). The allocation instruction may be applied to the above-described CBS method.

Then, one of the plurality of taxis received the command through the CBS terminal (not shown) installed inside the taxi transmits the dispatch request data to the dispatch server 60 (S60). At this time, the transmission method may be applied to the TCP / IP method (aka wireless Internet method). When sending the dispatch request data, the location data of the current taxi is also transmitted.

Next, the dispatch server 60 designates a customer and a taxi, and notifies the dispatch completion by a taxi (S70). At this time, the navigation device inside the taxi graphically displays the recognized customer location data and the current location data of the corresponding taxi. The technology of displaying the location data (including the GPS data) in conjunction with the navigation device inside the taxi is easy for those skilled in the art, and thus a detailed description of the configuration will be omitted. Such location data has the effect of making it easy and accurate even for a novice driver or an unfamiliar destination.

Then, the taxi to get on and off the customer transmits the data about the getting on and off and the current position data to the dispatch server (60) (S80). The transmission at this time is made by using a tachometer (fare meter) that is operated when the customer gets on and off. That is, whenever using this, the customer getting on and off information and the current position data is transmitted to the dispatch server (60).

However, if the position data check step (S30) is not confirmed, the voice recognition server 50 sends a recording command to the voice recording server 55. Accordingly, the voice recording server 55 records the voice of the customer (S90).

Then, the voice recording server 55 reproduces the recorded voice data to the operator in sequence (S100). Then, the operator hears the voice of the customer reproduced, grasps the destination, etc. and manually allocates the taxi (S110). At this time, the operator can use the database used by the dispatch server 60 to assist the dispatcher of the taxi.

When the taxi dispatch is completed, the taxi picks up the customer, and gets off at the destination, and reports the ride data and the current location data to the dispatch server 60 (S80). This makes it possible for a taxi to be dispatched even by the request of a visitor whose voice recognition is unclear.

5 is a detailed internal configuration of the voice recognition server 50 of FIGS. As shown in FIG. 5, the voice recognition server 50 is mainly composed of an ARS-IVR server 52, a TTS server 56, and an ARS server 57, and a customer at the bottom of the ARS-IVR server 52. An information DB 54 is provided, and a first major area coordinate DB 59 is provided below the ARS server 57.

The ARS-IVR (Audio Response Service-Interactive Voice Response) server 52 performs a voice conversation with a customer, and has a configuration for requesting or receiving various data from a connected server.

The customer information DB 54 is a database that defines and stores information about a customer. For example, fields related to a customer's name, gender, telephone number, address, customer grade, date of use, etc. are defined.

The TTS (Text to Speech) server 56 has a configuration for converting text data into a voice signal at the request of the ARS-IVR server 52.

The ARS (Audio Response Service) server 57 has a configuration of recognizing a voice of a customer, retrieving coordinate data from the first main local coordinate DB 59, and outputting it as position data. At this time, the first major regional coordinate DB 59 may be the same database as the second major regional coordinate DB 62 described above, or may be a similar database.

The operation of the voice recognition server 50 is as follows.

First of all, when a customer requests a telephone call for a taxi (1), the ARS-IVR server 52 searches the customer information DB 54 using this (2), and confirms the customer's information therefrom (3). ). Then, the ARS-IVR server 52 requests a voice conversion from the TTS server 56 (④). The TTS server 56 converts the text data into a voice signal and sends it to the ARS-IVR server 52 (⑤).

Then, the ARS-IVR server 52 asks the customer for the location of the received voice signal (⑥). At this time, one form of query may be "Please tell us your location." Responding to the customer's response (⑦) to this query, the ARS server 57 recognizes it as a letter and retrieves the coordinates (⑧). The retrieved coordinates are transmitted back to the ARS-IVR server 52 (⑨). Through this process, the voice recognition server 50 converts the voice of the customer into text data of a specific coordinate.

Although the present invention separates the voice recognition server 50 and the dispatch server 60 on the operator 40 side, it may be configured as one server incorporating such a function, if necessary, each of the large capacity Of course, it can be allocated as a separate server for each function.

The system of the present invention can be implemented as a series of instructions that can be read and executed by a computer, which instructions can be recorded on a record carrier. Examples of such a recording medium include a hard disk, a RAM device, a ROM device, a compact disk, a DVD, a CD-ROM, a magneto-optical disk, a floppy disk, a digital tape, a memory stick, and the like.

As described above, according to the taxi dispatch system using the telephone according to the present invention, when the location information of the customer is grasped from the voice of the customer and the taxi is automatically allocated and the voice recognition fails, the voice information of the customer is obtained. You can record a taxi and record it to the operator manually. Therefore, even a difficult voice of the customer can be allocated. This has the effect of overcoming the limitations of the conventional mechanical system (for example, the recognition rate limit).

And, even if the voice recognition fails to configure the taxi to be dispatched, to increase the utilization of the call taxi, customers can increase the reliability of the taxi dispatch.

In addition, the operator handles only the voice of the customer, which is very difficult to recognize, so that it can be implemented with a minimum of manpower and can satisfy various customer requests.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention. Accordingly, the appended claims will cover such modifications and variations as fall within the spirit of the invention.
