All elements of the display device 1 are mounted in a horizontally long flat rectangular device housing. Most of the front of the apparatus housing is a display screen 11 constituted by an LED dot matrix. An electric circuit device described below is built in a thick portion on the back side of the device housing.

  The display device 1 includes a PHS communication module 12. The PHS communication module 12 is housed in a small housing separate from the device housing of the display device 1, and as shown in FIG. 4, the PHS communication module 12 is housed in a recess in the upper right corner on the back of the device housing. However, the PHS communication module 12 is not fixed to this place but is attracted and positioned by a magnet, and the installation position can be changed by removing the PHS communication module 12 from this place. The PHS communication module 12 and the CPU board 13 in the apparatus housing are connected by a cable of about 1 meter. The installation position of the PHS communication module 12 is adjusted within the range of the length of this cable, and the base station of the PHS network 2 So that you can receive radio waves well.

  In this embodiment, an antenna is built in the housing of the PHS communication module 12, but it may be configured such that the position of the antenna can be adjusted by attaching it to the outside of the housing. In addition, the PHS communication module 12 may be built in the device housing of the main body, and only the antenna connected to the cable may be externally attached to the device housing so that the position of the antenna can be adjusted so that radio waves from the base station can be received well. .

  The CPU board 13 is a single board computer serving as the center of the display device 1, and a large-capacity flash memory 14 is externally attached. The video processing board 15 displays an image on the LED board 16 constituting the display screen 11 under the control of the CPU board 13. As will be described in detail later, the CPU board 13 transfers image data to be displayed to the video processing board 15 based on the schedule. This image data is stored in the video memory of the video processing board 15, read from the video memory by the processor of the video processing board 15, transferred to the LED board 16, and the light emission image by the LED dot matrix constituting the display screen 11. It becomes.

  Although omitted in FIG. 5, the power supply device is built in the device housing of the display device 1, and the power cable wired outside from the device housing is connected to an external commercial power outlet, so that the power supply device Commercial power is input. As shown in FIG. 4, a power switch 17 is provided on the side of the device housing, and the power of the display device 1 is turned on and off by manually operating the power switch 17.

  In the ROM in the PHS communication module 12, the PSID (corresponding to the device communication identifier) assigned to the module 12 is recorded and the equivalent to the server communication identifier assigned to the management server 5 is also recorded. ing. This PSID is also recorded in the ROM of the CPU board 13. The flash memory 14 connected to the CPU board 13 stores a group of files that constitute an operation program for the display device 1.

  In the ROM or the flash memory 14 of the CPU board 13, station opening process guide information and communication condition maintenance guide information are stored as display target information. The station opening process guide information may be deleted after the station has been opened and the user's operation program is stored in the display device 1 as will be described later. The flash memory 14 stores a flag for distinguishing between unopened / opened stations. This flag is set to an unopened station at the time of device shipment.

=== Operation of Display Device 1 ===
When the power cable of the display device 1 is connected to an outlet and the power switch 17 is turned on, the processor of the CPU board 13 operates according to the procedure schematically shown in the flowcharts of FIGS.

When the power is turned on, the processor checks a flag for distinguishing between unopened / opened stations. In this explanation procedure, it is assumed that the flag is not opened.
In the case of an unopened station, it communicates with the PHS communication module 12 to acquire reception intensity data of base station radio waves of the PHS network 2 and determines whether or not the reception intensity is equal to or higher than a reference level. At this time, the LED board 16 is controlled via the video processing board 15 so as to notify the user of the reception intensity and to display whether it is within or outside the service area. In the following description, the display control performed by the processor of the CPU board 13 is expressed as “display on the screen 11”.

If it is out of service area, a message explaining the working method is displayed on the screen so that the position of the PHS communication board 12 is adjusted based on the communication condition maintenance guide information stored in the ROM of the CPU board 13 or the flash memory 14. 11 is displayed.
If it is within the vicinity, as described in the beginning, a calling telegram for calling the management server 5 is transmitted to the PHS network 2. This calling message includes the PSID of its own display device 1 indicating the calling terminal and the communication identifier of the management server 5 indicating the communication partner.

  If for some reason the response from the management server 5 to the call cannot be confirmed, a message notifying the user of this is displayed on the screen 11 and the call is repeated according to a predetermined re-call procedure.

  When a communication link is established with the management server 5 responding to the call, communication with the management server 5 is started based on the station opening process guide information stored in the ROM of the CPU board 13 or the flash memory 14. A message that informs the user is displayed on the screen 11, and a message that guides how the purchaser of the display device 1 should proceed with the opening process is displayed on the screen 11.

  As described above, when the station is not opened, the display device 1 notifies the management server 5 that the station is not opened as a result. The processor of the CPU board 13 displays a guidance message on the screen 11 informing the user of how to proceed with the procedure to be performed next by the user based on the station opening process guidance information. The user accesses the management server 5 via the Internet 6 using a user computer (such as a personal computer or a mobile phone) according to the displayed guidance message.

=== Opening procedure by user computer ===
A user accesses the management server 5 on the Internet by a user computer and obtains a home page. There is an opening procedure request button on the cover page, and clicking this button takes you to a page with a mail address entry field and an execution button. If you enter the user's e-mail address and click the execute button, the message “Please wait, send me an e-mail” is displayed. Thereafter, a mail for opening procedure is transmitted from the management server 5, and the user receives it by the user computer. When a predetermined description is clicked in accordance with this mail guide, an opening procedure page is sent from the management server 5.

  In the opening procedure page, there are columns for entering various attribute information related to the user and the store such as address, company name, person in charge, telephone number, etc. in addition to the column for entering the device authentication number, user ID, and password. These items are entered and transmitted to the management server 5.

  The device authentication number is a unique number assigned to the purchased display device 1 and is a number written in a warranty card enclosed with the display device. The correspondence relationship between the device authentication number and the PSID (device communication identifier) assigned to the display device 1 is known by the manufacturer that shipped the product, and the correspondence information is stored in the storage device of the management server 5. Is recorded as “device list information” described above.

  When the management server 5 receives the information entered in the opening procedure page from the user computer, the management server 5 confirms that the received device authentication number exists in the “device list information”, and corresponds to this device authentication number. For the attached PSID display device 1, a new record in which the user ID / password and other user attribute information are associated is entered in the “opening device list information” described above. This completes the basic opening procedure, and this is notified to the user computer.

=== Creation / change of operation program by user computer ===
When the user of the opened display device 1 accesses the management server 5 by the user computer and authenticates with the user ID and the password, as described above, the general information resource (content database) and the display device 1 are exclusively used. Access to individual information resources (operation programs) is permitted. The flow of communication processing after this login is organized in the flowchart of FIG.

  For example, as disclosed in Japanese Patent No. 3957843, the operation program stored in the management server 5 is displayed on the monitor screen of the user computer in the form of a schedule table for one week, and the required time in the schedule table. By filling in or rewriting the contents of the frame, the contents of the operation program can be arbitrarily edited. For users who have just opened, the content database has several templates for operation programs (which can be viewed by users in the form of schedules) for various industries. You can read the description of the shape, select the one you like, and edit your operational program in a way that rewrites part of the schedule.

  The user does not need to complete the operation program editing work at one login opportunity to the management server 5, but can simply log in several times to complete the favorite operation program. If the operation program is sufficient, an update command is given from the user computer to the management server 5, and the operation program editing process is terminated.

  The management server 5 that has received the update command calls the corresponding display device 1 from the PHS network 2 based on the PSID associated with the user ID and the password. When there is a response from the display device 1 to the call, the operation program update process is started. If the communication link with the display device 1 cannot be established, the call is repeated in accordance with a predetermined re-call procedure, and if that is not possible, an e-mail is created to inform the user of the call, and the user ID and password are used. Send to the associated email address.

  As described above, in the operation program update process, first, the file identification list of the operation program (file set) held by the display device 1 is transferred to the management server 5. The management server 5 compares the received file identification list with that of the operation program of the display device 1 stored in the database, and transmits a new file related to the update to the display device 1. The display device 1 receives the new file, updates the operation program of the flash memory 14, and notifies the management server 5 that the update is completed.

  When the management server 5 receives the update end notification, it creates an e-mail notifying the user of the update and sends it to the e-mail address. If the update end notification is not received, the operation program update is completed normally. Notify users by e-mail that they have not done so.

  When the processor of the CPU board 14 in the display device 1 performs the operation program update process, if the flag is not yet opened, the processor switches to open. As a result, the display device 1 is actually opened.

=== Display device 1 already opened ===
When power is turned on to the display device 1 whose flag has been opened, the processor of the CPU board 13 proceeds from the first step of FIG. 6 to the routine of FIG. 7, and communicates with the PHS communication module 12 to communicate with the PHS network. The reception intensity data of the base station radio wave 2 is acquired, it is determined whether or not the reception intensity is equal to or higher than a reference level, and the display means notifies the user of the reception intensity and informs the user whether the area is out of range or not.

  If it is within the range, the PHS module 13 communicates with the management server 5 to notify the management server 5 of the start of the operation of the device together with the PSID of the display device 1, and skips this notification processing when out of the service area. In any case, it is next checked whether or not a valid operation program is stored in the flash memory 14. In a normal usage situation, the operation program is stored in the opened display device 1. In this case, the processor of the CPU board 13 is in a normal operation mode that operates based on the operation program of the flash memory 14.

  That is, based on the display schedule information in the operation program, the display target information (display content) in the operation program is sequentially read from the flash memory 14 and displayed on the screen 11. Of course, nothing is displayed during the time period set as display pause in the display schedule information. If the display pause time is long, the sleep mode (standby in the power saving mode) may be set.

The operation program held by the display device 1 is an operation program downloaded to the display device 1 from the operation program database of the management server 5 when the display device 1 has been opened and is already in operation. This operation program is an operation program edited by the user himself / herself by accessing the management server 5 via the Internet 6 using a user computer (such as a personal computer or a mobile phone).
However, there may be a case where an effective operation program does not exist in the opened display device 1 for some reason. In that case, display a message telling the user about that. If the management server 5 is accessed while determining that it is within the service area, but a communication link with the management server 5 cannot be established, this is displayed, and then normal operation processing is executed.
