A guide system and method.

In the case of using public transportation such as subways or buses, the most interesting thing is that users want to know where they have arrived and where they are going. In the case of a bus, you can visually check the signboards and milestones visible outside the window to determine the current location or check the route table attached to the bus. Not easy

In the case of the subway, if you do not hear the information of the next arrival station through the announcement, you cannot know the current location. Especially, in the middle point where the announcement does not come out, you cannot know the current location and the route information unless you check the route table attached to the vehicle. You do not know.

In order to solve this problem, the method of guiding the route information on public transportation such as subways and buses is currently connected to a CP (Contents Provider) server that provides route information using a mobile phone. When the starting point and the destination are input, the CP server provides the route information in the form of text through the starting point and the destination information. And inside some subways, the current location is guided by electronically blinking the current route point.

However, the current way of flashing the current route point is installed in the upper part of the door only the device is not guided to all the passengers, there is a problem that can not be easily confirmed in the case of full-scale subway.

In addition, the method of guiding the corresponding route information in the CP server is troublesome for the user to input a departure point and a destination, and it is not available without knowing the departure point and destination of the corresponding public transportation, and it does not provide information on the current location. There is.

The present invention is to solve the problems of the prior art, it is an object of the user to be able to guide the route information of the public transport easily boarded to the occupant with a mobile phone.

As shown in FIG. 1, the present invention provides a passenger cell phone 100, an area information relay device 200 installed inside or outside a public transportation means A, and an area broadcast installed at a stop such as a bus or a subway. Device 300.

In the present invention, the area information relay apparatus 200 and the area broadcasting apparatus 300 form a WPAN (Wireless Personal Area Network) and perform wireless communication between individuals. To this end, the area information relay device 200 and the area broadcast device 300 are built with one of the Bluetooth (Bluetooth) or Zigbee (Zigbee) module having the same communication standard.

In the following, a Zigbee module compliant with IEEE 802.15.4, which is one of the WPANs, will be described as an embodiment. ZigBee technology is mainly suitable for homenet and terminal application services because it transmits a small amount of control signals based on zone and uses low power. Therefore, in the present invention, since a Zigbee modem using a small amount of data transmission and low power is suitable, the following description will focus on the Zigbee modem.

Meanwhile, the area broadcasting apparatus 300 stores an installed zone, that is, an ID (unique identification code) for a stop, and broadcasts a beacon signal informing the stop ID at a set period. Since the area broadcast apparatus 300 only needs to transmit a station ID, it is preferable that the zone broadcast apparatus 300 be a zone identifier broadcast apparatus among Zigbee devices.

 The area information relay device 200 stores identification information of the installed public transportation means, that is, a bus running number in the case of a bus and a vehicle number in the case of a subway, and a broadcast signal for a stop ID from the area broadcasting device 300. That is, when receiving a beacon signal (beacon) signal stored in addition to the received station ID itself wirelessly broadcasts the identification information of the public transportation means. Here, since the area information relay 200 receives the station ID and broadcasts a signal corresponding thereto, the area information relay 200 is preferably a transceiver.

The zone information relay 200 varies the Zigbee topology as shown in FIG. 3 according to the size of the installed public transportation means. That is, in the case of a subway with a large size of public transportation, if a data is transmitted through one Zigbee module, an unreceivable area occurs. Accordingly, as shown in FIG. 3, the area information relay device 200 forms a network using a plurality of Zigbee modules to form a star structure, a cluster tree structure, a mesh structure, and the like, thereby eliminating an unreceivable area.

On the other hand, the mobile phone 100 of the present invention has a built-in or external ZigBee module, which is a WPAN module installed in the area information relay device 200 and the area broadcast device 300, and the station ID transmitted to the area information relay device 200; Receive a signal including identification information of the vehicle. When the mobile phone 100 receives identification information of a stop and a vehicle from the area information relay device 200, the mobile phone 100 receives and displays route information and current location information corresponding to the received information. There are two methods of receiving route information and current location information through identification information of the stop and the vehicle received from the mobile phone 100. These two methods will be described in detail with reference to the following embodiments.

2 is a view showing an installation state of the area broadcasting apparatus according to an embodiment of the present invention. For the present invention, while the communication between the area broadcasting device 300 and the area information relay 200 is performed smoothly, the area information relay device 200 transmits the arrival fact as soon as the public transportation arrives at a specific stop point such as a stop. It is desirable to be able to see.

Therefore, as shown in FIG. 2, Zone Identifier (ZI), that is, the zone broadcasting device 300 is installed on the route of public transportation, and the zone information relay 200 is installed at the front end side of the public transportation.

A route detecting unit 140 for grasping route information corresponding to the identification information, a display unit 150 for displaying based on the route information and character information indicating the current position, and a controller 120 for controlling the operation of each component. Include. Here, the route information may be information based on geographic information, but in consideration of the storage capacity of the mobile phone, the route information may be textual information.

Referring to the process of the second embodiment using the mobile phone 100 having the above configuration, the zone broadcasting apparatus 300 installed with the stop as a specific zone broadcasts the ID of the installed station at a set cycle (S701). . When the public transportation enters the stop in such a state, the area information relay device 200 installed in the public transportation receives the station ID broadcasted (S702), and the identification information of the public transportation stored with the received stop ID. The radio signal is broadcast internally (S703).

 Then, the passenger's mobile phone 100 receives the station ID and the identification information of the public transportation means through the Zigbee module 110 (S704), and thus the route detection unit 140 routes the identification information of the public transportation means. The route information stored in the information DB 160 is identified, and the current position matched with the corresponding route information stored in the route information DB 160 is identified through the stop ID (S705).

And based on the information grasped by the route detection unit 140, the character information generation unit 130 is the character information for the current location, that is, "in front of the Samsung-dong trade center." Alternatively, character information "here is the front of XX building XX building" is generated using the route information DB 160 (S706).

The character information and the route information thus identified are provided to the display unit 150, and the display unit 150 displays the route information and the character information on the screen (S707). In this case, it is preferable that the stop or the section of the corresponding location is displayed on the route information to be distinguished from other routes.
