DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat guidance system, and more particularly to a seat guidance system for guiding a passenger to a designated seat such as a train.

[0002]

2. Description of the Related Art A procedure in which a passenger purchases a reserved seat ticket of a train at a window of a station and goes to a designated seat of a designated train will be described as follows. Check the train number of the specified train by looking at the face of the purchased reserved seat ticket. At the station (platform), confirm the position of the train number of the designated train on the display board, etc., and determine the direction. Get on the train with the specified train number. Check the seat number and confirm the seat number. The specified seat number position is inferred by looking at the seat number at the top of the seat in the train. Get to the designated seat. As described above, conventionally, the passenger must check the train number and the seat number by himself and make his own judgment until he arrives at the reserved seat of the train, and the seat guidance that guides the passenger to the designated seat is The system did not exist.

[0003]

As described above, conventionally, there has been no special seat guidance system, so that passengers first need to determine whether the number of their own train is ahead or behind. . For this reason, it is necessary to check the display board or ask the station staff for your own, and it is difficult to determine whether your seat is ahead or behind the train even after you get on the train. It was necessary to look at the seat number attached and to guess where he was and to get to his seat.

Therefore, it takes time and trouble to reach the designated seat. In addition, it is difficult for elderly people or passengers with poor eyesight to check the train position display board and the like, so it took a longer time to reach the designated seat. The present invention has been made to solve the above-described problem, and has as its object to provide a seat guidance system capable of automatically guiding a passenger to a designated seat of a designated train.

DETAILED DESCRIPTION OF THE INVENTION In the present invention, Bluetooth (B
A low-power, short-range, two-way wireless communication system called “bluetooth” is used in the seat guidance system.
Before describing the embodiments of the present invention, a low-power short-range wireless communication system will be described. Bluetooth is a system for performing short-range two-way wireless communication between a master (server) and a slave (client).
The frequency band uses the ISM (2.4 GHz band) which does not require a special license and can be used in common throughout the world.

[0008] In this radio communication system, identification numbers (ID numbers) are individually assigned so that specific terminals can be identified. The ID number is stored in a non-volatile memory so that it cannot be rewritten. Also, it has a function of detecting that a communication partner has entered a communication area before performing data communication. Then, after detecting a communication partner, a connection partner is selected or it is determined whether or not the connection partner is suitable, and a connection process (call) for performing data communication is performed.
I do.

Next, a connection method between the master and the slave will be described. In the seat guidance system of the present invention, the mobile portable receiving terminal becomes a master, and the vehicle transmitter and the platform transmitter become slaves. FIG. 2 shows a flowchart in the case where an unspecified terminal having the same function is detected and the user determines until connection. Assuming that the mobile receiving terminal on the detecting side is a master, the master side has a detecting and connecting button. The connection process starts (step 201), and when the detection button is pressed (step 202), the master transmits a detection signal (step 203) and waits for reception of a response signal from the slave.

[0010] The side to be detected (slave: a transmitter for a vehicle and a transmitter for a platform) periodically performs a receiving operation to receive a detection signal.
The D number and the unique function are sent back to the master as a response signal. When the master successfully receives the response signal (step 204), it compares the master function with the slave function (step 205). If the comparison results match, the ID number of the terminal having the same function is displayed on the display (step 206). Thereafter, when the user wants to connect, the master selects the connection partner and presses the connection button to start the connection operation and start data communication (steps 207 to 207).
210).

FIG. 3 is a diagram showing the configuration of a piconet.
By configuring a link centered on a master called a piconet, point-to-multipoint communication becomes possible. When the communication connection is started, the master assigns a temporary address to the slave. The slave determines from the received address whether it is addressed to itself, and if it is addressed to itself, takes in the data; otherwise, it discards it. Even during the data communication between the master and the slave, the slave can be added at any time by executing the terminal detection and connection procedure in the communication area. Further, at the end of data communication, the temporary address assigned to the slave can be discarded.

As described above, it is possible to communicate with a large number of terminals by repeatedly adding and releasing slaves in a time sharing manner. Further, a security function is added to the communication between the master and the slave. Therefore, the master and the slave each have an input device for inputting a password and a display for displaying the input character. The terminal has a security function of permitting connection only when the same password is input when starting a communication connection.

After detecting that a communication partner has entered the communication area and making a connection, the communication partner is usually in a communication state and exchanges data periodically. When exchanging data, the state where the data transmitted from the other party can not be received,
If the communication is continued for a certain period of time, the out-of-area detection can be performed in both terminals by determining that the communication partner has left the area.

FIG. 1 is a diagram showing a configuration of a seat guidance system according to an embodiment of the present invention. In the present invention, a plurality of vehicle transmitters A to D and a plurality of platform transmitters 1a to 3b are installed in the connected vehicle 10 and station (platform) 20, respectively. The platform transmitters 1a to 3b are installed on the platform and near the doors of each train vehicle.

Each of the transmitters 1a to 3b has an individual identification number and transmits an identification signal corresponding to the individual identification number. The radio wave coverage of the transmitters 1a to 3b is set so as to slightly overlap between two adjacent ones at a connection portion of the vehicle 10 connected as the transmitters 1b and 2a and the transmitters 2b and 3a. Further, transmitters A to D are installed in each train of the train 10.
These transmitters A to D include a platform transmitter 1a.
3b, and has an individual identification number different from that of 〜3b, and transmits an identification signal corresponding to the identification number.

The ranges of the radio waves of the transmitters A to D are set so that adjacent ones thereof slightly overlap each other, and the radio waves are set so that they can also reach the width direction of the train. Therefore, if the length of the vehicle is long, five or more transmitters may be required, and if the length of the vehicle is short, three or less transmitters may be required.

The mobile portable receiving terminal carried by the passenger is shown as a receiver R on the platform 20, and the receiver R is provided with guide means for guiding the user to a designated seat while moving. Have been. Further, when the vehicle number and the seat number of the designated vehicle are designated and inputted using the input means of the receiver R, the identification numbers of the platform transmitters 1a to 3b closest to the designated vehicle are stored. At the same time, the identification number of the transmitter closest to the designated seat is also stored. In the case of the embodiment shown in FIG. 1, the identification numbers of the platform transmitter 1b and the vehicle transmitter B are stored in the receiver R. The receiver R is provided with a display unit capable of displaying characters and arrows or a voice synthesizing function.

Next, the operation until the passenger reaches the target designated seat will be described using the seat guidance system shown in FIG. There is a receiver R at the X mark of the platform 20,
It is assumed that the intended designated seat is near the transmitter B of train number 1. When the designated seat number is input to the receiver R, the receiver R stores the identification number of the transmitter 1b at the vehicle entrance closest to the designated seat number and the identification number of the transmitter B closest to the designated seat.

If the receiver R moves in the direction of the transmitter 3b and receives the signal of the transmitter 3b, a display indicating that the receiver R is moving in the opposite direction is displayed on the display unit of the receiver R. ,
Alternatively, it is emitted by voice guidance. If the receiver R moves in the direction of the transmitter 3a and receives the signal of the transmitter 3a, the display unit of the receiver R is instructed to proceed further, or the voice guidance gives the instruction. Is issued. When the receiver R keeps moving and receives the signal of the transmitter 1b, it is displayed that it is the entrance closest to the designated seat, or it is emitted by voice guidance. When the receiver R enters the vehicle, it receives the signal of the transmitter D,
The display unit of the receiver R indicates that the vehicle should go further,
It is emitted by voice guidance. When the receiver R keeps moving and receives the signal of the transmitter B, it is displayed that it is the nearest place to the designated seat, or it is issued by voice guidance. Therefore, the passenger can confirm his or her seat number at that position and sit on the designated seat.

As described above, the seat guidance is performed while performing the above-described Bluetooth communication using the vehicle transmitter and the platform transmitter as slaves and the receiver serving as the mobile reception terminal as a master. In the case of the above-described embodiment, it is necessary to specify and input the vehicle number and the seat number to the receiver R. Lending can save time and effort for passengers to input, which is more convenient for elderly people and the like.

[0021]

As described above, according to the present invention, only by inputting the vehicle number and the seat number to the mobile portable receiving terminal, the guide to the entrance to the designated vehicle is automatically made on the platform, and the user can get into the vehicle. From, guidance to the vicinity of the designated seat is automatically made, so that the user can quickly reach the target seat. Therefore, it is possible for an elderly person or a passenger with poor eyesight to reach the designated seat without fail.
