The display item is a display item distributed to the display unit 105, and the code number is the content of the content to be displayed, and is a code as shown in Tables 1 to 4.

  Therefore, the operator of the management center 301 displays the distribution information editing screen shown in FIG. 2A on the display unit 403 of the information server device 400, and operates the input / output unit 401 to display the train numbers shown in Table 6. With reference to the display management table of X1001, for example, a code number is input to each display screen 206 of the first car. As an input method, for example, a code number can be input from a keyboard, but the code numbers in Table 6 can also be input by a drag and drop operation with a mouse. FIG. 2B shows a state in which a code number is input to the display screens 206-1, 206-2, 206-3, and 206-4 of the vehicle number X1001. For example, when the input to all the display screens from the first car to the tenth car is completed, the determination is made by pressing the enter button. In FIG. 2B, for example, on the display screen 206-1 (corresponding to 105-1) of the display device 103-1 of the first car, one advertisement 01000-00001 is displayed for the identification codes A1 and A2. Represents that. That is, the advertisement 01000-00001 indicates that the advertisement of the advertisement section A station-B station, time 5: 00-18: 00, and A department store advertisement is distributed from Table 4. In addition, in the identification code B1 of the display screen 206-2 (corresponding to 105-2) of the display device 103-2 of the first car, the operation information 00001-0010, that is, the operation information of the central line shown in Table 2 is displayed. It is displayed. The identification code B2 indicates that the weather information 00001-00010, that is, the weather information of each place shown in Table 3 is displayed. The same applies hereinafter.

  Now, when the distribution information to the display device in the vehicle of each train is confirmed on the distribution information editing screen shown in FIG. 2A, the control unit 404 of the information server device 400 once stores the edited distribution information in the external storage device. The distribution information table 411 of 405 is stored. This is shown as a distribution information table for vehicle number X1001 in Table 7.

  Table 7 represents, for example, control data to be displayed on the display unit 105 of each display device 103 in the vehicle shown in FIG. 1A and image data for display. For example, the advertisement of the code number 01000-00001 is displayed on the display screen 105-1 of the display device 103-1 of the first car of the train number X1001. Here, train number: X1001, vehicle number: No. 1 car, No. 2 car,..., Screen identification codes A1, A2,..., Code numbers: 01000-00001,. Is control information for controlling. Further, the image data of the display content is indicated by DA1. The image data DA1 is, for example, image data that is appropriately read from the distribution information 412 and subjected to image processing in a form that is displayed on the display screen 105 by the image processing unit 409. Hereinafter, the same applies to each of the display screens 105 of the other display devices 103.

  And before operation of a train etc. is started, the control part 404 reads the delivery information table of the train number X1001 shown in Table 7 from the delivery information table 411 of the external storage device 405, the line connection part 407, the transmission line 302, For example, the information is written into the recording server 604 of the in-vehicle information server 101 with the train number X1001 via the wireless relay station 303.

  In the vehicle information server 101, the distribution information is distributed to the display device 103 in the vehicle of the train number X1001 based on the distribution information table shown in Table 7 written in the recording server 604. In other words, the control unit 603 reads the distribution information from the recording server 604, distributes the distribution information to the control unit 104 of each display device 107, and temporarily stores it in each storage unit 704. Table 8 shows control information and display data stored in each storage unit 704.

  Table 8 shows control information and display data temporarily stored in the storage unit 704 (indicated by storage unit 1 to storage unit 4) of the display control unit 104 of the in-vehicle display device 103. For example, screen identification codes A1, A2, code numbers 01000-00001, display items: advertisement and data DA1 are transmitted to the control unit 104-1 of the in-vehicle display device 103-1 of the first car, and the storage unit 704 (distinguishable) Therefore, it is temporarily stored in the storage unit 1). And the control part 104-1 of the in-vehicle display apparatus 103-1 of No. 1 car reads a control signal and image data from the memory | storage part 1, and displays them on the display part 105-1. Therefore, in the in-vehicle display device 103-1 of the first car, the advertisement of the A department store is displayed on the entire surface of the display screen 105-1 (a screen combining A1 and A2) in the A station-B station section at 5: 00-18. : Displayed for 00 hours.

  Similarly, the control unit 104-2 of the in-vehicle display device 103-2 of the first car includes a screen identification code B1, a code number 00001-00001, display items: operation information, data DA2, a screen identification code B2, and a code number 00010. -00010, display item: weather, data DA3 is transmitted and temporarily stored in the storage unit 704 (displayed as the storage unit 2 for distinction). Then, the control unit 104-2 of the in-vehicle display device 103-2 of the first car reads out the control signal and the image data from the storage unit 2, and the operation information is displayed in the screen identification code B1 of the display unit 105-2. The weather information is displayed on the screen identification code B2. The same applies hereinafter. In this way, the display unit 105 can display the same screen on the entire surface, or display separate images in two parts, so that it can easily cope with diversification of needs and services. It is possible to realize a mobile in-vivo information distribution system that can distribute distributed distribution information.

  In the above embodiment, the case where the distribution information is transmitted from the information server device 400 of the management center 301 has been described. However, the present invention is not limited to this. For example, the distribution information table of the external storage device 405 of the information server device 400 The distribution information once stored, for example, the table shown in Table 7 is once read by the input / output unit 401 to a recording medium such as an optical desk. The train crew or station staff can bring this recording medium such as an optical desk into the train, read it by the reading unit 605 of the in-vehicle information server 101, and store it in the recording server 604. However, since distribution information such as weather information, operation information, and news changes every moment, it goes without saying that it is better to transmit the latest information from the management center 301.

  Next, a method for making the screen displayed on the display device 103 one screen or two screens in the embodiment described above will be described below with reference to FIGS. First, in order to make the distribution information one screen or two screens, it is necessary to image-process and process the distribution information stored in the external storage device 405 in advance. This image processing and processing is performed by the image processing unit 409 of the information server device 400. A block diagram of a schematic configuration of the image processing unit 409 is shown in FIG. In FIG. 10, reference numeral 1001 denotes an input terminal for distribution information to be processed and processed. In this embodiment, data stored in the distribution information 412 of the external storage device 405 is input. This data is generally analog data. Analog data input to the input terminal 1001 is converted to digital data by the A / D converter 1002 and input to the image converter 1003.

  The image conversion unit 1003 performs predetermined image conversion, distribution information for one-screen display is stored in the one-screen storage unit 1006, and distribution information for two-screen display is stored in the two-screen storage unit 1007. Then, the operator operates the operation display unit 1005 according to whether to display the one-screen display distribution information or the two-screen display distribution information on the display screen 105 of the display device 103 described above, and the control unit 1004. In accordance with the control, the selection unit 1008 is driven to output one-screen display distribution information or two-screen display distribution information from the output terminal 1009, and this output signal is accumulated in the distribution information table 411. That is, the data DA shown in Table 7 is obtained.

  Here, the image conversion unit 1003 will be described. Note that the image conversion unit 1003 can be configured by, for example, an FPGA (Field Programmable Gate Array). First, as the display unit 105 of the display device 103 used in the present invention, for example, a high-definition liquid crystal display is used, and as distribution information, conventional NTSC video data is used. FIG. 11 shows, for example, a screen obtained by digitally converting a conventional NTSC image. For example, the scanning line has 525 lines and the number of pixels is 525 pixels × 700 pixels. FIG. 12 shows a high-definition liquid crystal display. For example, scanning lines are 1236 lines, and the number of pixels is 1236 pixels × 1628 pixels. In addition, a present Example is an example and is not restricted to this.

  Thus, the screen shown in FIG. 11 is, for example, distribution information, and a case will be described in which this distribution information is displayed on the high-definition liquid crystal display shown in FIG. In FIG. 12, 1201 shows a display screen of operation information, for example, 1202 shows a display screen of weather information, for example. When two screens are displayed on the high-definition liquid crystal display in this way, the operation information display screen 1201 is assigned to a display portion surrounded by P1, P2, P5, and P6, for example. This can be realized by assigning the operation information display screen 1201 to the horizontal direction P1: 77th pixel to P2: 776th pixel and to the vertical direction P5: 356th pixel to P6: 880th pixel. . The weather information display screen 1202 is assigned to a display portion surrounded by P3, P4, P5, and P6, for example. For this purpose, the weather information display screen 1202 can be assigned to the horizontal direction P3: 853rd pixel to P4: 1552th pixel, and the vertical direction P5: 356th pixel to P6: 880th pixel. . In this way, by performing pixel conversion in the image conversion unit 1003, two screens can be displayed on a high-definition liquid crystal display.

  Next, a case where one screen is displayed on a high-definition liquid crystal display will be described. FIG. 13 shows a screen obtained by digitally converting a conventional NTSC image, for example, shown in FIG. 11. For example, a screen having 525 scanning lines and 525 pixels × 700 pixels is a high-definition liquid crystal display. A case of displaying on a screen 1301 is shown. In this case, a case where the screen of 525 pixels × 700 pixels shown in FIG. 11 is displayed as a screen 1302 enlarged about 2.3 times is shown. If it does in this way, a screen can be enlarged, information, such as a character display, becomes easy to see, and the service for a passenger improves. In the above description, the NTSC system image has been digitally converted for the sake of simplicity. However, an analog system can be realized by performing the same processing.

  Next, another embodiment of the present invention will be described with reference to FIGS. 14, 1401-1, 1401-2, 1401-3,... Indicate in-vehicle display devices. Note that when a display device is represented, it is referred to as a display device 1401. 1402-1, 1402-2, 1402-3,... Are control units of the display device 1401. In addition, when representing a control part, it calls the control part 1402. 1403-1, 1403-2, ... 1403-6, ... are display units. Note that the display unit is referred to as a display unit 1403 when represented. In this embodiment, each of the display devices 1401 includes two display units 1403, for example, display units 1403-1 and 1403-2. And the display apparatus 1401 which consists of such a pair of display part is arrange | positioned at the upper part of the door of a vehicle as shown, for example in FIG.1 (B). In addition, the same code | symbol is attached | subjected to the same thing as FIG. In FIG. 14, each display unit 1403 is composed of one display unit, and can be composed of, for example, a liquid crystal display that displays conventional NTSC image data.

  FIG. 15 is a diagram for explaining an information delivery method of the in-vehicle information delivery system shown in FIG. 15, 1501-1, 1501-2,... 1501-8 correspond to the display units 1403-1, 1403-2,. In addition, the same code | symbol is attached | subjected to the same thing as FIG. FIG. 15 is a distribution information editing screen similar to that described with reference to FIG.

  The operator of the management center 301 displays the distribution information editing screen shown in FIG. 15 on the display unit 403 of the information server device 400, and operates the input / output unit 401 to train number X1001 shown in Table 6 described above. A table similar to the display management table is created, and this table is referred to. For example, each display screen 1501 of the first car is displayed on the display screen 1501 according to the distribution information determined in advance as described in the previous embodiment. ~ Enter the delivery code number shown in Table 5. As an input method, for example, a code number can be input from a keyboard, but can also be input by a drag and drop operation with a mouse. If it does in this way, a code number will be inputted into display screen 1501-1 of vehicle number X1001, 1501-2, ... 1501-8 (corresponding to display parts 1403-1, 1403-2, ..., respectively). It will be in the state. For example, when the input to all the display screens 1501 from the first car to the tenth car is completed, the determination is made by pressing the enter button 207. In the case of the present embodiment, since it is not necessary to perform image processing and processing such as displaying one screen on the display unit or displaying two screens as in the previous embodiment, the image of the information server device 400 is displayed. It is not necessary to use the function of the processing unit 409. In addition, the method for distributing the distribution information assigned to each display unit 1501 as described above to the display unit 1403 of the display device 1401 of each train is the same as that described in the previous embodiment.
