Description

  The present invention relates to a train radio system and a central control device used therefor.

  Train rails are divided into zones of several hundred meters to several kilometers, and a base station is provided for each zone. As the train travels on the rails, the zones are updated one after another. When entering the new zone, the necessary communication is performed with the base station corresponding to the new zone. All the base stations can communicate with the central control unit, and the central control unit monitors the operation status and performs necessary train control. The central control device is connected to the central command room and receives various commands from the central command room or sends necessary operation data to the central command room. The central command room has a command operation panel, and the command operator sends a necessary command to the central control device via the command operation panel, and receives necessary operation data from the central control device and displays it appropriately.

  Each base station automatically detects that a train has entered the zone and sends it to the central control unit and the central command room via this unit. Thus, the central control unit and the central command room can automatically know the in-zone zone of the train and perform necessary monitoring and management. In many cases, between the central command room and the train, the crew and the command operator in the train talk about the belief in the call or command. For example, there are train schedule delays, delay reasons, signal lights, various other operations and train management calls.

In such a call, the command operator side connects the line for the call by operating the command operation panel, but there is a problem that the operability of the panel is poor.
That is, there is a command operation panel in the central command room, and this panel includes at least an operation bulletin board, a handset, a zone switch, and a numeric keypad, and an operation when the command room operator calls the vehicle individually is as follows:
(1) On the operation bulletin board on the operation panel, confirm in which zone the train with the vehicle number is located.
(2) Lift the handset of the command operation panel and press the corresponding zone switch (use an illuminated pushbutton switch for the zone switch).
(3) By inputting the train number to be called from the numeric keypad on the command operation panel, the corresponding vehicle is called.
Because this configuration and procedure are required,
・ When the command operator calls the vehicle, there are many series of operations and workability is poor.
・ Incorrect train number input,
Then there was a problem.

  On the other hand, if the number of base stations increases and the number of trains to be operated increases, it becomes necessary for the crew members to call and communicate with each other between the trains. In this case, the command operator in the central command room became a relay person, and after making line connections, calls and communications between crew members were made. In this manner, there is a problem that when the command operator is absent, it is impossible to make a call or contact between crew members. The case where the command operator is absent is, for example, during meals at night, during maintenance at night, or during emergencies. Therefore, it is desirable that calls and communications can be made between trains without the intervention of crew members.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a train radio system and a central control device used in the train radio system that enable a call between crew members between trains without intervention of a command operator in a central command room.

The present invention is a train radio system for performing a call between a train on a zone-divided track and a command operation room via a base station and a central control device,
In the central control unit, a communication path switching means is provided, and the switching means is a train connected to the base station via a call or command operation room between the command operation room and the train via the base station. Disclosed is a train radio system having a route selection means for communication between trains or between trains connected to a base station without going through a command operation room.

Furthermore, the present invention is a central controller in the train radio system,
A communication path switching means is provided, and the switching means is a communication between the command operation room and the train via the base station, a call between trains connected to the base station via the command operation room, or a command operation. Disclosed is a central control device having route selection means for communication between trains connected to a base station without passing through a room.

  Furthermore, the present invention discloses a central control device in which the route selection means selects a route for a call between trains without going through a command operation room during maintenance of the train radio system.

  According to the present invention, the operability of the command operation panel can be improved. Furthermore, according to the present invention, it is possible to make calls between trains without intervention of an operator in the central command room.

  FIG. 1 is a structural example diagram of a command operation panel (command operation device) of the present invention. FIG. 2 is a structural example diagram of the switch 2 with train number display of the present invention. As shown in FIG. 1, the command operation panel 100 includes a handset 1, a switch 2 with a train number display corresponding to the number corresponding to the number of zones (for the sake of simplicity, 4 × 4 16 zones) and a computer system 3 (dotted line The numeric keypad, the display, etc. are on the panel). A specific example of the switch 2 is shown in FIG. 2, in which a 4-digit numeric display LED display unit 20 and an illumination type push button switch unit 21 are vertically provided and integrated. The LED display unit 20 is configured to automatically display a train number (for example, 4 digits) when the train 6 enters the zone. As a result, the command operator can visually recognize which train has entered which zone. On the other hand, the button switch unit 21 is configured to enable automatic dialing of the train number being displayed on the LED display unit 20 on the upper side of the switch unit 21 when pressed by the operator. These mechanisms are implemented as a system.

  FIG. 3 shows an example of a train radio system. There is a base station 5 corresponding to the zone, which is interposed between the train 6 and the central controller 4 and relays communication between them. The central command room 10 and the central controller 4 are also connected by bus or radio. In the central command room 10, there are a plurality of command operation panels 100 that receive operations from the command operator 101. The management for each zone is performed by the central command room 10 and the central control device 4 via the corresponding base station 5, and necessary train information is taken in and various commands are sent to the train 6.

  An example of the processing flow of the computer system 3 of the operation panel 100 is shown in FIG. As a matter of course, the computer system has a CPU, a memory, a keyboard, a mouse, and a display. In FIG. 4, first, the operation is started (S30), and it is determined whether or not there is a train zone approach by taking in the incoming line information via the corresponding base station 5 and the central controller 4 (S31). The zone is confirmed (S32), the train number is confirmed (S33), and the train number is displayed on the incoming zone corresponding LED indicator 20 (S34). The train number may be sent together with the incoming line information, or sent from the central control device 4 as a result of the central control device 4 receiving the input information and performing diamond management.

  Next, it is determined whether or not the switch 21 is on (S35). This ON is realized when the operator presses the lower switch 21 integrated with the LED display 20 displaying the train number. When the switch 21 is turned on (S36), automatic dialing is performed toward the train of the train number being displayed (S37). Then, calling / calling is performed (S38). When the talk ends (S39), it is determined whether or not the operation is finished.

  According to this embodiment, the train number is automatically displayed on the zone-corresponding LED indicator 20, and if the corresponding switch 21 at the lower part thereof is turned on, the train number is automatically dialed in. . Previously, dialing in by depressing the numeric keypad corresponding to the train was able to be achieved only by turning on the switch.

  In addition to LEDs, a matrix type or other display type train number indicator can be adopted.

A wireless device that enables a crew member to communicate and communicate between trains without intervention of a command operator, which is a second embodiment, will be described.
An operation system having a large number of base stations (BS) will be described. For example, it is assumed that there are 45 base stations, and an inter-train crew call is possible between all of the 45 base stations without the intervention of a command operator.

  FIG. 5 is an overall system example diagram of the second embodiment. An example of a subway train is shown, and it is assumed that a plurality of trains 6A and 6B are on the rail. Each train 6A, 6B has a vehicle operation panel TCP and a radio device CRE operated by a crew member, and performs radio communication with zone-compatible base stations 60-1 to 60-n via antennas. For the subway, the base stations 60-1 to 60-n communicate with the antenna via the leaky coaxial cable LCX.

The number of base stations n is as large as n = 45, for example. The base station corresponds to the zone.
The central control device 4 includes call control devices 51 and 52 and switches SW1 to SW3 in addition to the processor MPU 50 that performs various processes and management. In addition, it has a data table and database for diamond management. Furthermore, although it has a system path for performing communication of signals other than communication and its control means, it is omitted in the drawing.

The central command room 10 includes a command operation panel 100 and other various processing, input / output, and display means. FIG. 5 shows a route for calling and its means. That is, the voice output path 1A from the handset 1, the voice input path 1B from the base station, the voice return path 11A, the switch 24 that is turned on when the voice return is interrupted and turned off when the return is utilized, and the amplifier (mixer) ) Have 23 mag. Voice return refers to the time when voice is sent from a train to another train.
The switches SW1 to SW3 have the following two modes.
Normal call mode: SW1 and SW2 are both ON and SW3 is OFF.
Exceptional call mode: SW1 and SW2 are both OFF and SW3 is ON.
The normal call mode refers to a time when a call is made between the command operator 101 and the train, or when a call is made between the trains via the command operator. Direct calls between trains are very dangerous because they can lead to uncontrolled operation between trains. It is a principle of train operation management that a command operator is always intervened and the operation is performed with the monitoring and understanding of the central operator. Therefore, in the normal call mode in which the switches SW1 and SW2 are ON and SW3 is OFF, an instruction or command from the operator 101 is sent to the route 1A (MIC line) → SW1 → control device 51 → corresponding base. The call from the corresponding train is sent to the command room 10 via the corresponding base station → control device 52 → SW2 → VOIC line. If the switch 24 is turned off, there is no return voice. If the switch 24 is turned on, the voice is transmitted to other trains.

Exceptional call mode is a typical example of train radio equipment maintenance (especially when checking train radio via a central control unit or base station), but it can also be used when special permission is granted in an emergency. It is. In the exceptional call mode, both SW1 and SW2 are turned off and SW3 is turned on, and a system route from the control device 52 to 51 is formed without intervention of a command operator, and a direct call between trains is performed.
SW1, 2 and 3 can be turned on and off manually or in software.

  During maintenance, a maintenance operation device dedicated to maintenance (also referred to as a maintenance console) is connected to the central control device 4, and the central control device 4 and the base stations 60-1 to 60-n are inspected and wirelessly connected to the train. Check the communication. Functions include hardware inspection and software inspection. Furthermore, there is also an inspection of its function with the central command room 10 interposed. Among such inspection types and types, there is an inspection of inter-train calls. In addition, there is an inter-train call inspection without the central command room 10 and an inter-train call inspection without the central command room, and the embodiment shown in FIGS. 5 and 6 can be used during the latter inspection. In that case, the inter-train call can be inspected by the configuration as shown in FIGS.

FIG. 6 is a detailed example diagram of the control devices 51 and 52. However, the total number of base stations n = 45, which is divided into 3 units of 15 stations, and one unit is shown in FIG. Further, a switch 55 corresponding to SW3 in FIG. 5 exists between the devices 51 and 52. The control device 52 has interfaces 501 to 515 and mixer circuits 521 to 535. Interfaces 501 to 515 are connection circuits with the base stations BS1 to BS15, and audio mixer circuits 521 to 535 are other than the self, except for signals from the own base station (the x mark indicates disconnection of the line). The signals from the stations are combined. The reason for self-exclusion is that resonance of return sound occurs in the crew of the train from which the uttered sound is generated, that is, to prevent self-resonance of the sound.
Further, a 16th mixer circuit 536 is provided. The mixer circuit 536 inputs signals from all 15 base stations and synthesizes them. The combined output SE1 is input to the other two units.

  The control device 51 includes audio mixer circuits 561 to 575, and takes in and combines the combined outputs of the corresponding mixer circuits 521 to 536 and the SE1 corresponding outputs SE2 and SE3 of other units via the switches 541 to 555. Each combined output is sent to the corresponding base station BS1 to BS15.

  According to the above embodiment, the switches SW1 and SW2 are turned off and the switch SW3 is turned on (the switch 55 in FIG. 5 is turned on), so that calls between trains can be made without intervention of the central command room. became.

  In the case of a call between trains, there are two examples: a case in which a communication line between itself and the other party is formed like a telephone line, and an example in which such a line is not formed and broadcast communication is sent to all. There can be one. The former call line format requires dial-in. Such communication line formation is omitted in FIGS. On the other hand, in the latter case, it is not particularly necessary to form a telephone line, and the configuration shown in FIGS.

In FIG. 5, the central control device 4 is convenient for expansion or reduction of functions by adopting a method in which boards are grouped according to function and stacked (building method). In this case, there are the following as targets for substrate formation.
(1) an interface between the MPU, the control devices 51 and 52 and the BS, a command operation panel interface,
(2) Control devices 51 and 52 in each unit when unitized with 3 as shown in FIG.

  Although the base station and the zone are made to correspond one-to-one, the relationship between the base station and the zone includes correspondence examples such as 1: n, n: 1, and m: n.
