  In the conventional status display device, each indicator lamp indicates the status of each device. Therefore, an indicator lamp that turns on / off as many as the number of devices whose status is to be checked is required. There has been a problem and a problem that it is not possible to sufficiently meet the demand for space saving (see, for example, Patent Document 1). In addition, in the case of LED type indicator lamps, it is difficult to replace the LED when it is determined that it will darken as the years pass and the amount of light at the time of lighting will be insufficient, and it can be used semi-permanently. (For example, refer to Patent Document 2).

  For example, in a train cab state display device, when a conventional state display device is used for a vehicle that travels across a plurality of sections of a route section (hereinafter referred to as section) A and section B, In each section, it is necessary to install an indicator lamp to display the operating state of all necessary devices. For example, in section A, the operating state display of ATS (automatic train stop device) is required, but section B On the other hand, in section B, it may be necessary to display the operation state of an ATO (automatic train operation apparatus) that is unnecessary in section A. For this reason, if all indicator lights for displaying the device status required in each section are provided, there is a problem that it may be unclear which device indicator light should be viewed in which section. is there. For example, there is a problem that it takes time for the driver's confirmation work, such as wondering whether the ATS indicator light is not lit or not in the corresponding section.

  This invention is made in view of the above, Comprising: It aims at obtaining the state display apparatus and state display method which can confirm the state of each apparatus mounted in a vehicle rapidly.

  In order to solve the above-described problems and achieve the object, the state display device according to the present invention includes information on operation states of a plurality of devices mounted on a vehicle that travels in a plurality of different route sections, and at least during traveling. Based on the operation information of the vehicle including the route section information of the vehicle, in accordance with the route section that is running, calculating means for selecting display items about the operating state of the equipment required in the route section, and running Display means for switching the display according to the route section and displaying the selected display item.

  According to this invention, corresponding to the route section in which the vehicle is traveling, the display items for the operation state of the necessary device are selected, and only the necessary device state is displayed by switching the display. There is an effect that the state of each device can be quickly confirmed.

  Embodiments of a status display device according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

Embodiment 1 FIG.
FIG. 1 is a diagram illustrating a configuration of a status display device according to the present embodiment, FIG. 2 is a diagram illustrating an example of display items displayed on the display unit 1 of the status display device, and FIG. FIG. 4 is a flowchart for explaining the operation of the state display device, showing another example of display items displayed on the display means 1.

  In FIG. 1, for example, a state display device installed in a train is shown, and the state display device according to the present embodiment includes a display unit 1 and a calculation unit 2. In addition, the devices 3 to 5 represent a plurality (three in the illustrated example) of devices mounted on the train, and the on-board information management device 10 provides train operation information (for example, route section information, diagram information, etc.). I manage. The devices 3 to 5 are each connected to the calculation means 2 by the transmission line 6, and the operation state information output from each of the devices 3 to 5 is input to the calculation means via the transmission line 6. The on-board information management information device 1 is also connected to the calculation means 2 via the transmission line 6, and the train operation information output from the on-board information management device 10 is sent to the calculation means 2 via the transmission line 6. Entered. Furthermore, the calculation means 2 and the display means 1 are connected via the transmission line 6, and the calculation means 2 performs calculations based on information acquired from the devices 3 to 5 and the on-board information management device 10. The contents to be displayed on the display means 1 are selected and output to the display means 1. As described above, the display unit 1 receives the operation state information of the devices 3 to 5 through the calculation unit 2.

  In FIG. 2, the display items displayed on the display unit 1 are only the operation state information of the devices necessary for the section A, and the display unit 1 displays the operation states of the devices 3 to 5 received from the calculation unit 2. Is displayed on the display screen. The display means 1 is provided in a driver's cab, for example, and is composed of a liquid crystal or plasma screen, etc., and the screen configuration such as contents, types, and number of items of display items can be arbitrarily changed by software processing of the calculation means 2 Yes. The display item 100a indicates a section (section A in the illustrated example), and the display item means 100b to 100d indicate the states of the respective devices 3 to 5. In the case of FIG. 2, for example, the display item means 100b and 100c are turned on to indicate that the display item 100b corresponding to the device 3 and the display item 100c corresponding to the device 4 are operating normally. . In addition, in order to distinguish between the lit state and the unlit state, for example, the solid display / frame is filled with a predetermined color when lit, and the flat display / frame is not painted when turned off. It can be.

  FIG. 3 shows the contents of the screen displayed on the display means 1 when the train is driving from the section A to the section B shown in FIG. The display item 100a on the screen indicates that the section operated by the train is section B. When the section B is changed, the contents of the device to be displayed are also changed, and some display items necessary for the section A shown in FIG. 2 are unnecessary in the section B of FIG. That is, since the train control in the section A is performed by the ATS, the display items 100e to 100i relating to the operation of the ATS are required to be displayed. On the other hand, since the train control in the section B is performed by ATO, display item 100j related to ATO is required to be displayed, but display items 100e to 100i related to ATS operation are not required. Therefore, although the contents, types, and number of items of display items to be displayed differ depending on the section, the display position of the common items is always the same position so that there is no mistake in viewing.

  Next, with reference to FIG. 4, the operation of the state display device when the train is entering the sections A and B, that is, the state display method according to the present embodiment will be described. When the train starts operation, the calculation means 2 receives the train operation information from the vehicle information management device 10 mounted on the vehicle at a constant cycle (S1) and also receives the state information from each state display target device. (S2). Then, if the currently traveling section is section A (S3) from the received train operation information, a display item necessary for section A is selected (S4), and a screen corresponding to section A is displayed on display means 1 (S4). 2) is displayed (S5).

  If the traveling section is not section A (S3), it is determined whether it is section B (S6). In the case of the section B, as in the case of the section A, the display items necessary for the section B are selected (S7), and the screen corresponding to the section B (FIG. 3) is displayed on the display means 1 (S8). The above procedure is performed until the end of operation (S9). In the present embodiment, the case where the display screen is switched between the two sections A and B has been described, but the same applies to a plurality of arbitrary sections.

  Switching between screens is necessary when there is a section, but the user does not need to be aware of screen switching. When starting operation, the operation information from the first station to the last station is input from the vehicle information management device 10 to the computing device 2, so that the running pattern is determined by the internal processing of the computing device 2, and the first station to the last station. It is possible to set in the arithmetic unit 2 which station to pass and which section to run by.

  According to the present embodiment, the display means 1 is a liquid crystal or plasma screen or the like, and the screen configuration such as the content, type, and number of items of display items can be arbitrarily changed by the software processing of the computing means 2, and the mounted device Since the state is displayed on the screen, there is no need for an indicator light for confirming the state, and there is an effect that it is possible to reduce parts and mounting wiring and solve the space-saving problem. Furthermore, the light quantity at the time of lighting does not become insufficient like an LED lamp, and the user can always see in a comfortable state.

  In addition, since the contents displayed on the screen of the display means 1 are changed depending on the section, only the item of the state of the equipment required in the section is displayed, so that the necessary contents can be clarified, There is an effect that the state of each device can be quickly confirmed.

Embodiment 2. FIG.
5 and 6 are diagrams showing a configuration of the state display device according to the present embodiment, and are diagrams for explaining redundancy in the present embodiment. In addition, the apparatuses 3-5 show the case where there are three types of apparatuses mounted on the vehicle, as in the first embodiment. As shown in FIG. 5, the difference from the first embodiment is that, for example, driving information (brake notch information, speed information, traffic signal information, etc.) provided on the cab is necessary on the liquid crystal display or plasma screen. Display means 7 (second display means) to be operated, and calculation means 8 (second display means) for calculating the contents for taking the operation information from the on-board information management device 10 and displaying it on the display means 7 and outputting them to the display means 7 The calculation means) is provided, and the calculation means 2 (first calculation means) and the calculation means 8 are connected to each other via the transmission line 6 to share information with each other. Normally, the display means 1 (first display means) displays the state of each device 3-6 as described in the first embodiment, while the display means 7 is necessary for running the vehicle. Information is displayed.

  Therefore, for example, as shown in FIG. 5, when the display unit 1 fails and the statuses of the devices 3 to 5 cannot be displayed, the calculation unit 8 sharing the information of the calculation unit 2 displays the display unit 1. A screen to be displayed on the display means 7 can be displayed on the display means 7. Similarly, as shown in FIG. 6, when the display means 7 breaks down and information necessary for driving the vehicle cannot be displayed, the calculation means 2 sharing the information of the calculation means 8 causes the display means to 7 can be displayed on the display means 1.

  As described above, according to the present embodiment, the calculation means 2 and the calculation means 8 are connected to share the respective information, thereby switching the display contents of the display means 1 and the display means 7 to display the screen. Therefore, there is an effect that the redundancy of each display means can be improved.
