BEST MODE FOR CARRYING OUT THE INVENTION

First example (train identification on railways)

A first embodiment of the present invention will be described. In the present embodiment, in a railway system, when an on-board crew such as an operator brings a mobile terminal onto a train, information (notification notification information and operation management information) relating to the train on which the vehicle is operating is transmitted to the mobile terminal. Will be described. For information provision in the railway operation management system, information to be provided to mobile terminals is managed for each train. However, the portable terminal to be carried and the control device on the train are not directly connected. Therefore, in order for the central processing unit to communicate information to each mobile terminal, the central processing unit communicates directly with the mobile terminal, not via a train. For this reason, the central processing unit must know which terminal is on which train when communicating information. In the present invention, the central processing unit detects the train line (position) and the line number (position) of the portable terminal, compares the line number (position) between the train and the portable terminal, and if the train and the portable terminal are on the same line, The mobile terminal is linked to and the information to the associated train is delivered to the linked mobile terminal.

Hereinafter, a system configuration according to the present invention will be described with reference to FIG. In the present embodiment, as shown in FIG. 1, a crew comprises a portable display terminal 101 which is carried by a crew and carried on a train, and a central processing unit 102 which provides information to the portable display terminal 101. The portable display terminal 101 includes a terminal control unit 104 for controlling the portable display terminal 101, a terminal mobile unit number storage unit 106 for storing a terminal number for identifying each portable display terminal, and a central unit. A terminal that communicates with the processing unit 102. A communication unit 103, a terminal that stores the identification number of a mobile unit such as a specified crew train, a mobile unit number storage unit 107, a central processing unit 102. It consists of a terminal display unit 105 for displaying information from the terminal.

The central processing unit 102 includes a central control unit 109 that controls the entire system, a mobile unit detection unit 110 that detects the position of a mobile unit (train) for each mobile unit number, and a mobile display terminal. The terminal position detector 112, which detects the position of 101 for each display terminal, the position of the mobile object from the mobile object detector 110 and the position of the portable display terminal from the terminal position detector 112 are used as keys. Close to moving objects (on the same line The collation unit 108 that identifies the mobile display terminal. The mobile display terminal identified by the collation unit 108 is a mobile object composed of a train number and the corresponding display terminal number. It comprises a mobile / terminal management table storage unit 113 that stores the management table 114, and a central communication unit 111 that communicates with the portable display terminal 101.

The operation of this embodiment will be described with reference to FIG. When the crew brings the portable display terminal 101 near the train, the terminal position detection unit 112 of the central processing unit 102 detects the position of the portable display terminal 101 by a method described later. The terminal position detection unit 112 notifies the central control unit 109 of the detection result (pair of the line number and the terminal number of the display terminal: for example, terminal number 1 on line 1). The central control unit 109 sends the detection result report from the terminal position detection unit 112 to the mobile unit detection unit 110 and sends the train number of the train on the detected line to the mobile unit detection unit 110 ( (Column number). The moving object detecting unit 110 identifies the train number (for example, B on line 1) currently located on the designated line by the method described later, and returns it to the central control unit 109. The central control unit 109 instructs the collation unit 108 to collate the detected mobile display terminal with the moving object (train). The collating unit 108 includes the data of the pair of the portable display terminal and the display number from the terminal position detecting unit 112 (for example, the terminal number 1 on the line 1), and the mobile unit from the mobile unit detecting unit 110. It compares the location information (line B to line 1) and identifies the trains on the same line as each mobile display terminal 101. In the case of FIG. 1, it is determined that the portable display terminal 101 having the terminal number 1 is on board B, and the result is returned to the central control unit 109. The central processing unit 102 informs the portable display terminal of the result of the collation by the collation unit 108. The central control unit 109 sends a central communication unit 111 and a terminal communication unit to the detected portable display terminal based on the result of the collation by the collation unit 108. The number of the train on which the mobile display terminal is boarding (for example, B in the case of terminal number 1) is notified through 103. Based on the terminal number and the train number notified from the terminal communication unit 103, the terminal control unit 104 of the portable display terminal firstly determines the terminal of the own portable display terminal stored in the terminal number storage unit 106. Refer to the number to confirm that the information provided is for you. If the confirmation fails, a notification of the confirmation failure is sent to the central control unit 109 via the terminal communication unit 103 and the central communication unit 111. If it can be confirmed that it is the information of the self-display terminal, it is assumed that the notified train number (B) is the train on which the user is boarding, and the terminal / mobile number storage unit 107 And stored in the terminal display unit 105. In addition, the central control unit 109 notifies the central control unit 109 of the confirmation via the terminal communication unit 103 and the central communication unit 111. The central control unit 109 sends a confirmation notification from the portable display terminal. Only when it is received, the pair of the train number and the terminal number (in the case of B) that is confirmed in the mobile unit's display terminal management table 114 stored in the mobile unit / display terminal management table storage unit 113 Store the terminal number 1). At this time, if the information of the display terminal 1 has already been stored, the train number portion is updated.

When notifying information from the central processing unit 102 to the portable display terminal 101, the central communication unit 111 specifies the terminal number, and in addition to the one-to-one communication, the blower that specifies only the train number. Two methods of communication by broadcast are implemented. In the case of one-to-one communication in which a terminal number is specified, the central control unit 109 communicates the content to be communicated from the central communication unit 111 to the portable display terminal 101 that provides information. When the information from the terminal communication unit 103 is one-to-one communication, the portable display terminal 101 receives the communication content as information to itself, and the terminal display unit 101 0 5 Display contents. On the other hand, in the case of a broadcast in which a train number is specified, the central control unit 109 transmits The train number to be communicated with is specified, and the information is output from the central communication unit 111 to all portable display terminals that can communicate information. If the information received by the terminal communication unit 103 is broadcast data, the mobile display terminal extracts the train number from the data, and stores the train number, terminal, and mobile number stored in the data. Compare with the train number stored in storage unit 107, and ignore if different. If the train numbers are the same, the communication content is received as the information to the user, and displayed on the terminal display unit 105.

FIG. 2 shows a configuration example of the moving object detection unit 110. As shown in Fig. 2, the moving object detection unit 110 detects the on-line detection unit 202, which detects the physical position of the train described in Fig. 3, and the logical on-line condition (the train status of each train at each time). A diagram storage unit 204 that stores a diagram 206 in which the number and the line location (number line) are described in advance, and a physical line location (specifically, a starting circuit number). Outputs the train number at the logical position (line) from the line information storage unit 203 that stores the line information 205 that describes the relationship with the logical position (line). The train on-rail position detecting unit 201 is provided. Next, the operation of the moving object detection unit 110 will be described with reference to FIG. When the train position detection unit 201 is inquired of the train number on the line (for example, line 1) from the central control unit 109 in FIG. 1, the line information 2 in the line information storage unit 203 is sent. From 06, the starting circuit number on the specified line is extracted. For example, in the case of line 1, the starting circuit 1. The train on-line position detecting unit 201 requests the on-line detecting unit 202 to detect whether or not the train is actually present on the extracted starting circuit number. If there is no train, the train location detection unit 201 notifies the central control unit 109 that there is no corresponding train. On the other hand, when the train on-line position detecting unit 201 finds out that the train is on the designated start-up circuit via the on-line detecting unit 202, the train on-line Current time Search using 2 0 7 as a key. The diamond 206 stores a train number and a logical position (for example, a line number) for each time as shown in FIG. Basically, the railway system should control trains on this train schedule. Therefore, the train position detection unit 201 sets this timetable 206 to the current time.

The search is performed using 2 07 as a key, and the train number that should be on the designated line (for example, line 1) from the central control unit 109 is extracted. For example, in the case of Fig. 2, it can be seen that the train on line 1 of 1: 1: 01 is train B. The train location detection unit 201 outputs the train number B to the central control unit 109.

FIG. 3 shows the configuration of the on-rail detection unit 202. As shown in Fig. 3, in the railway system, the track through which the train 304 passes is divided into a plurality of parts (track circuits 302,

It is composed of a voltage detection unit 301 that detects the change in the voltage by passing a current from one of the lines. Train 304 is the starting circuit 302,

If it is not above 303, the line is electrically open, and the voltage detector can detect a high voltage (for example, a voltage of 3 V or more). On the other hand, when the train 304 enters the starting circuits 302 and 303, the starting circuits 302 and 303 are short-circuited by the axle of the train 304. For this reason, the voltage level that can be detected by the voltage detection unit becomes lower than a certain value (for example, 0.1 V). Thereby, voltage detecting section 301 detects that the train is on the starting circuit. When the train is on the starting circuit, the voltage detection unit 301 outputs the number of the short-circuited track circuit to the train location detection unit 201 in FIG.

FIG. 4 shows the configuration of the terminal position detection unit 112. FIG. 4 shows an example in which the terminal position detection unit 112 detects the position of the portable display terminal 101 using the directivity of a wireless antenna. As shown in Fig. 4, the terminal position detection unit 112 is composed of a plurality of antenna groups (antenna 1: 406, antenna) with strong directivity in the wireless base station 400 installed in each home. 2: 407), multiple antennas An antenna switching unit 405 for switching between 406 and 407, similarly, a radio transmitting and receiving station 404 for performing radio transmission and reception using the switched antenna in the radio base station 403, and a radio base station 400. 3 is a terminal position detection control unit for controlling terminal 3 and identifying a terminal based on wireless transmission / reception status, and antenna information storage for storing antenna information 4 10 describing the relationship between each antenna and a line number at which communication is possible. Section 402. The terminal position detection control section 401 controls the antenna switching section 405 in the radio base station 403 periodically to switch between the antenna groups 406 and 407. When antenna groups 406 and 407 are switched, the area that can be received (in this case, the line where the train is located) is switched. In addition, the terminal communication unit 408 in the display terminal 1 attempts to communicate with the radio base station 403, and periodically broadcasts its own terminal number. For example, when terminal 1 is on a train 1, that is, on line 1, the terminal communication unit 408 in the display terminal 1 tries to communicate with the wireless base station 403, and the terminal number Broadcast. Here, when the terminal position detection control unit 401 controls the antenna switching unit 400 to switch to the antenna 1: 406, the radio transmission / reception unit 4004 transmits the terminal communication in the display terminal 1. The terminal number is received from section 408. Upon receiving the terminal number, the radio transmitting / receiving section 404 notifies the terminal position detection control section 401 of the received terminal number. The terminal position detection control unit 410 uses the antenna information 410 in the antenna information storage unit 402 to determine the number of the line that seems to have a terminal with the terminal number received from the number of the currently used antenna. Search for. The terminal position detection control unit 410 notifies the central control unit 109 of the pair of the received terminal number and line number as a detection result. If there is no communication response after a certain period of time, it is determined that there is no display terminal in the communication area of the antenna, the next antenna is switched, and communication from the portable display terminal 101 is waited. In the above method, if there is a possibility that radio waves may reach the next home depending on the radio power, the terminal position detection control unit 401 sends the transmission power to the radio transmission / reception unit 4 04. By giving an instruction to lower it, the range of radio waves can be controlled.

FIG. 5 shows a second configuration of the terminal position detection unit 112. Although the configuration in Fig. 4 detects terminals using wireless directivity, this configuration uses wireless signal strength. As shown in Fig. 5, multiple wireless base stations 404 and 501 are installed for each line. At this time, the display terminal 1 sometimes communicates with a plurality of wireless base stations 4003 and 501, but at this time, the reception strength at the time of communication is checked in order to confirm which line is being used. Use. As shown in FIG. 5, the terminal position detecting section 401 is connected to a group of wireless base stations 4003, 501 installed corresponding to the respective lines and a wireless transmitting / receiving section 4004 for performing wireless transmission / reception within the group. , 502, and the terminal location detection control unit 401, which controls the wireless base stations 400, 501 and identifies the terminal from the wireless reception strength status, and among the wireless base stations, A base station information storage unit 503 stores base station information 504 that describes a relation with a line number having a strong reception strength. The terminal position detection control section 401 periodically and sequentially sends a plurality of wireless base stations 400 3 and 501 to the wireless transmitting and receiving sections 4 04 and 5 in each of the wireless base stations 400 and 501. 0 2 Send a command to send a terminal call signal. Upon receiving the terminal call signal, the terminal communication section 408 of the portable display terminal 101 returns the terminal number in the portable display terminal 101. Upon receiving a response from an updatable terminal, the radio base stations 4003 and 501 measure the intensity and report the intensity to the terminal position detection control unit 401. The terminal position detection control unit 401 issues a terminal call signal generation command to the wireless base stations 400 and 501, and stores the individual reception strengths of the terminal groups that return. I do. The terminal position detection control section 401 is connected to each mobile display terminal. For each terminal 101, the wireless base station 4003, 501 that has communicated most strongly among all the wireless base stations 403, 501 is specified. In addition, the terminal position detection control unit 401 determines the relationship between the wireless base station information storage unit (503, 501 stored in the 503 and the position (line number)). By referring to the indicated wireless base station information 504, the line number of each terminal is specified, and the number is reported to the central control unit 109.
