  The conventional information display system has the following problems, which are not considered or described in the conventional patent literature.

  In the case of providing information in an apartment house, in a single apartment house, a certain house displayed information with new arrival information in the morning, but some houses received information only when there was new arrival information in the evening. If acquisition is delayed, there is a problem that unfair feeling about information acquisition occurs. The problem becomes more serious as the information becomes more useful.

Also, if you want to actively provide information to the user, there is little opportunity to get the information just waiting for the connection from the user, but when new information is updated, there is new information. By telling the user, the opportunity for the user to obtain information can be increased. However, if the information acquisition interval for checking whether there is new information from the information terminal is shortened, the presence / absence of new information can be communicated, but if the information acquisition interval is shortened, a request for confirming whether there is new information will be processed even if the information has not been updated. Therefore, the server system is required to have more processing capacity than is really necessary.

  In the first place, information handled by an information display system with information actively provided to users is often displayed after obtaining necessary information and processing it into an easy-to-understand state. The update timing is often known in advance by the information providing side, and there has been a problem that useless connection occurs when the timing of new arrival information acquisition is determined by setting the information terminal.

  Also, even if the new arrival information acquisition time is designated by time, the load on the server is concentrated at a time, so that the processing that should be prepared by the server becomes very high. In other words, even if the information is small, whether there is new information or not, communication via the Internet is necessary to acquire the information. Therefore, when acquiring information from a large number of information terminals, There is a problem that the server to be provided requires a very high processing capacity. At the same time, there is a problem that it is necessary to secure a communication path for information to and from the housing complex.

  In addition, the information providing server updates some new information every day, but if the information includes information such as emergency notification information or introduction of new services that the user wants to see in detail, the information provider In order to indicate that there is no new information until all the necessary information has been read, the server that is the information provider must read There is a problem in that it is necessary to determine and notify the information terminal of new arrival information presence / absence information.

  In order to resolve this issue, the quality of the information read by the information provider is required, so there is no information that the server needs to see in detail at the timing when the information terminal acquires and displays the information. It is necessary to have a mechanism for obtaining new arrivals presence / absence information indicating whether or not new arrivals are present.

  However, normally, the display information processing means for displaying information uses software having an independent function for displaying an HTML file for displaying information, generally called browser software. Since browser software as a display information processing means basically has only an information display function, there was a function for checking whether there is new information regularly or when acquiring or displaying information to the server on the information providing side, or there was new information Sometimes it is difficult to realize the function of controlling the display means unique to the information terminal.

  The present invention solves the above-described conventional problem. The information terminal and the server share group information as an information display unit, and whenever the information terminal comes to check whether there is new information, the server An object is to provide an information display system in which information terminals of the same group can confirm the presence or absence of new information at the same time by specifying the next information acquisition timing.

  In order to solve the above-described conventional problems, the information display system and the program thereof according to the present invention share the group information as the information display unit between the information terminal and the server, and whenever the information terminal comes to check whether there is new information. The server specifies the next information acquisition timing for each group information, so that information terminals of the same group can confirm the presence or absence of new information at the same time, and whenever the information is confirmed, the control information acquisition means By acquiring new information presence / absence information, new information presence / absence notification by a server instruction can be performed.

  In the information display system and the program of the present invention, the information terminal and the server share group information as an information display unit, and whenever the information terminal comes to confirm the presence or absence of new information, the server obtains the next information for each group information. By specifying the timing, the information terminals of the same group can confirm the presence / absence of new information at the same time, acquire the new information presence / absence information at the time of information confirmation, and notify the presence / absence of new information by server instruction it can.

  A first invention is an information display system comprising a plurality of information terminals having a group as an information display unit and a server that communicates with the information terminal and provides information, wherein the server defines the group of information terminals.

Belonging group information storing means for storing the group to which the user belongs, terminal side communication means for communicating with the server, control information acquiring means for acquiring next information acquisition timing and new arrival information presence information from the server Display information processing means for performing a process capable of acquiring and interpreting information from the server according to an instruction from a user and displaying the information, and notifying the control information acquisition means of a control information acquisition instruction, and information obtained from the server. Display means for displaying, next information acquisition timing storage means for storing next information acquisition timing obtained from the server, and terminal control means for controlling the operation of the information terminal, wherein the information terminal is connected to the server. There is new information on the server based on the information acquisition timing for each group submitted from the next information acquisition timing submission means The information terminal is configured as an information display system in which the control information acquisition unit acquires new information presence / absence information from the server and performs new information presence / absence notification when the user confirms new information. And the server share the group information as the information display unit, and every time the information terminal comes to check whether there is new information, the server specifies the next information acquisition timing for each group information, so that the information terminal of the same belonging group Therefore, it is possible to provide an information display system that can confirm the presence or absence of new information at the same time and can notify the presence or absence of new information by a server instruction when the user confirms the information.

  In the second aspect of the invention, the next information acquisition timing submitted from the next information acquisition timing submitting means is set as a time interval so that the information terminal can accurately set the date / time to be the same as the server time. An information display system that does not need to be maintained can be provided.

  According to a third aspect of the present invention, in order to align the next information acquisition timing submitted from the next information acquisition timing submission unit for each group of the information terminals, a difference between a scheduled time for storing information in the information storage unit and a current time is calculated.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 shows a block diagram of an information display system according to the first embodiment of the present invention.

  In FIG. 1, the server 101 includes a group information storage unit 102, an information storage unit 103, an information submission unit 104, a next information acquisition timing submission unit 105, a server side communication unit 106, a new arrival information presence / absence information submission unit 117, and a server control unit 107. Composed.

  The information terminal 108 is composed of belonging group information storage means 109, display means 110, next information acquisition timing storage means 111, terminal side communication means 112, display information processing means 115, control information acquisition means 116, and terminal control means 113. . Reference numeral 114 denotes the Internet that connects the server 101 and the information terminal 104. The Internet 114 is not limited to the Internet and may be a communication network.

  The server 101 is a workstation, the group information storage unit 102, the information storage unit 103 is database software, the next information acquisition timing submission unit 105, the server side communication unit 106, the server control unit 107 is an OS, and a memory. , A storage device, a mother board having a network connection function, a belonging group information storage means 109, a next information acquisition timing storage means 111, a terminal side communication means 112, a control information acquisition means 116, and a terminal control means 113, a microcomputer, This configuration can be easily realized by using browser software for interpreting HTML information and converting it into a display format for the display information processing means 115 and a touch panel capable of displaying to the user and accepting operations. it can.

  Although one information display terminal is shown in FIG. 1, in reality, for example, a plurality of information display terminals are installed in an apartment house. And management of the information terminal for every apartment is performed using group information.

The group information is composed of, for example, 16-digit numbers. The first 8 digits are a code indicating the same information group, and the next 8 digits are an individual identification code. The number of digits in the group information may be any number. Needless to say, you can use other symbols instead of numbers.

  When the information terminal 108 is installed in the apartment house A, the apartment house B, and the apartment house C, “00000001”, “00000002”, “00000003” are assigned to the same information group information in each apartment house, and individual identification is performed. The room number of each apartment is used for the code. For example, a rule for assigning “00000101”, “00000201”, and “00000301” as the individual identification codes in the 101 room, 201 room, and 301 room of the apartment house A is defined. As a result, the group information of room 101, room 201, and room 301 of apartment house A is determined as “0000000100000101”, “0000000100000201”, and “0000000100000301”, respectively.

  By determining the group information in this way, when installing the information terminal 108, it is only necessary to tell the installation worker from the server 101 an 8-digit number applicable to the entire apartment house. If the instructions are simplified and encrypted communication is used for communication, there is no fear of analogy.

  The operation and action of the information display system configured as described above will be described below with reference to FIG.

  (1) First, the preparation operation S1 will be described.

  Before the information terminal 108 is installed, group information is registered in the group information storage unit 102 of the server 101 (S201).

  The group information is input by the installation operator through the touch panel of the display unit 110 of the information terminal 108, and the control information acquisition unit 116 stores the group information in the belonging group information storage unit 109 (S202).

  In order to improve the security, to avoid number assignment that is easy to imagine, the server 101 side stores a number issued at random for each same information group on the server side and notifies the information terminal 108 installation operator to notify the group information. Needless to say, the data may be stored in the storage unit 102.

  (2) Next, the new arrival information confirmation operation S2 will be described.

  Immediately after the preparation stage S1 ends, an initial value (for example, 0:00 every day) is set as the next information acquisition timing. When the preparation stage S1 is completed and the terminal control unit 113 confirms that the timing set in the next information acquisition timing storage unit 111 has arrived, a command is issued to the control information acquisition unit 116 to start connection to the server 101 ( S203).

  The control information acquisition unit 116 uses the terminal-side communication unit 112 through the terminal control unit 113 and submits the group information stored in the belonging group information storage unit 109 via the Internet 114 to the server 101, so that the new arrival information is detected and the next time. An inquiry about information acquisition timing is made (S204).

In the server 101, the server control unit 107 receives the communication content through the server side communication unit 106, and checks the group information storage unit 102 to check whether a correct group has been submitted (S205). Next, the new information presence / absence information storage unit 117 confirms the presence / absence of new information corresponding to the group submitted to the information storage unit 103 (S206), and the next information acquisition timing corresponding to the submitted group is the next information acquisition timing. Submission means 10
5 (S207).

  If the administrator of the server 101 matches the next information acquisition timing registered in the next information acquisition timing submitting means 105 with the schedule for processing the new information and registering it in the information storage means 103, the information terminal 108 sends the information to the server 101. It is possible to minimize the frequency of connection.

  The server control unit 107 transmits the presence / absence information of new arrival information and the next information acquisition timing to the control information acquisition unit 116 of the information terminal 108 through the Internet 114 using the server side communication unit 106 (S208). The control information acquisition unit 116 displays the presence / absence of new arrival information to the user by displaying the presence / absence of new arrival information on the display unit 110 by the terminal control unit 113 according to the acquired presence / absence of new arrival information (S209). Further, the acquired next information acquisition timing is stored in the next information acquisition timing storage unit 111 (S210).

  (3) Finally, the information browsing operation S3 will be described.

  When the user is notified of the presence of new arrival information in S209, the user operates the touch panel of the display unit 110 and issues an information request instruction to the server 101 by the display information processing unit 115 (S211). The information request is submitted to the server 101 by the terminal control means 113, and the server control means 107 receives the information request. The server control means 107 processes the information stored in the information storage means 103 using the information submission means 104, and simultaneously updates the information in the new arrival information presence / absence information submission means 117 (S212), and sends an information response to the information terminal 108. Is returned (S213). The information response result is displayed on the display means 110 by the terminal control means 113, and the user can browse new information (S214).

  Here, the display information processing unit 115 makes an information request (S211) and simultaneously notifies the control information acquisition / acquisition unit 116 that an information browsing operation has been performed (S250). Upon receiving the notification, the control information acquisition means 116 makes a control information (new arrivals presence / absence information and next information acquisition timing information) request (S251) by the same operation as (S204), and the server 101 performs group information inquiry / control information confirmation. The same operation as (S205) to (S207) is performed (S252), and the control information is transmitted to the control information acquisition unit 116 by a control information response (S253). If the new information presence / absence information of the obtained control information is no new information, the control information obtaining unit 116 displays no new information on the display unit 110 by the terminal control unit 113, and information that needs to be confirmed by the user Is informed (S254).

  In general, the display information processing means 115 for displaying information uses software having an independent function for displaying an HTML file for displaying information, generally called browser software. Since the browser software as the display information processing means 115 basically has only an information display function, there is a function for checking whether there is new information periodically or when acquiring / displaying information to the server on the information providing side. It is difficult to realize the function of controlling the display means unique to the information terminal. However, by using the mechanism as described above, it is possible to add a notification function to the control information acquisition unit 116 to the display information processing unit 115 that is usually provided as general-purpose browser software for displaying Internet contents. Acquisition of information presence / absence information can be realized.

  In S208 of the above-described operation, if the information on the next information acquisition timing is designated at a time interval such as 60 minutes from the current time, the information terminal 108 only needs to count the relative time from the next information acquisition timing acquisition time. Even if the information terminal 108 is difficult to hold the current date and time, the presence or absence of new information can be confirmed at the instructed time.

  By the operations (1) to (3) as described above, the information terminal 108 and the server 101 share group information as an information display unit, and the information terminal 108 checks the presence / absence of new information every time 101 designates the next information acquisition timing for each group information by time, so that the information terminals 108 in the same group can confirm the presence or absence of new information at the same time. It is possible to provide an information display system capable of notifying the presence / absence of newly arrived information.

  In addition, by setting the next information acquisition timing as a time interval, an information system in which the information terminal does not need to hold the date / time can be obtained.

  In addition, in order to acquire information specific to the information server in general-purpose browser software created for the purpose of displaying the contents of the Internet, the function of notifying the arrival of new information by the server instruction at the time of information confirmation by the user It can be realized with only a simple modification that incorporates a notification function to the software.

(Embodiment 2)
FIG. 3 is a block diagram of an information display system according to the second embodiment of the present invention. In FIG. 3, reference numeral 301 denotes a next information acquisition timing calculation means.

  The operation and effect of the information display system configured as shown in FIG. 3 are basically the same as the method of specifying the time interval at the next information acquisition timing of the first embodiment described in FIG. The difference from the first embodiment is the calculation method of the next information acquisition timing information acquired in S207.

  For example, when considering a general apartment house, the time to turn on the information terminal 108 for the first time is different because the time of moving in varies. Therefore, if a long time such as 360 minutes is specified as the time interval, it becomes a time interval from the power-on time. Therefore, it can be seen that there is new arrival information at 7:00 am in one house, but in one room at 1:00 pm Otherwise, there will be a situation where new information cannot be found.

  When the server control unit 107 acquires the next information acquisition timing from the next information acquisition timing submission unit 105, the next information acquisition timing submission unit 105 causes the next information acquisition timing calculation unit 301 to calculate the next information acquisition timing.

  The next information acquisition timing calculation unit 301 is instructed by the administrator of the server 101 to calculate “scheduled time for processing new information and registering in the information storage unit 103” registered for each group in the next information acquisition timing submission unit 105. The time difference used as the next information acquisition timing is calculated and returned to the next information acquisition timing submission means 105. The next information acquisition timing submitting means 105 delivers the time interval returned here to the server control means 107 as the next information acquisition timing.

  As described above, if the time interval calculated by the information acquisition timing calculation unit 301 is used as the next information acquisition timing, if the next information acquisition timing is simply operated at the time interval, The problem that the information acquisition timing is different can be solved.

By the operation described above, the next time for calculating the difference between the scheduled time stored in the information storage unit 103 and the current time in order to align the timing submitted from the next information acquisition timing submission unit 105 for each information terminal group. The information acquisition timing calculation means 301 is provided, and by specifying the next information acquisition timing by the difference between the next scheduled time and the current time, even if the activation time of the information terminal 108 is different, the terminals belonging to the same group can be specified by the time interval specification. It is possible to provide an information display system that can confirm the presence or absence of new information at the same time.

(Embodiment 3)
FIG. 4 is a block diagram of an information display system according to the third embodiment of the present invention. In FIG. 4, 401 is a dispersion time calculation means. This configuration can be easily realized by using a random number calculation function for the distributed time calculation means 401.

  The operation and action of the information display system configured as shown in FIG. 4 is basically the same as the method for specifying the time interval at the next information acquisition timing of the first and second embodiments described with reference to FIG. is there. The difference from the first embodiment is the calculation method of the next information acquisition timing information acquired in S207.

  When the server control unit 107 acquires the next information acquisition timing from the next information acquisition timing submission unit 105, the next information acquisition timing submission unit 105 receives the next information by the same operation as the first embodiment and the second embodiment. The acquisition timing is returned.

  Here, the server control unit 107 makes an inquiry to the distributed time calculation unit 401. The distributed time calculating means 401 performs random number calculating means, calculates a predetermined range of distributed time (for example, 0 to 30 minutes), and returns the distributed time as the calculation result to the server control means 107. The server control means 107 adds the dispersion time obtained here to the next information acquisition timing to obtain the next information acquisition timing.

  As a result, even within the same group, the information acquisition timing of the information terminals of the group can vary depending on the dispersion time.

  Preferably, if this dispersion time is set to a small one, an unfairness related to information acquisition that a house will be displayed with new arrival information only in the evening and information acquisition will be delayed even though it is in the same group A feeling becomes small.

  With the operations described above, when specifying the next information acquisition timing, the server load is distributed by distributing the server load, and the terminals in the same group confirm whether there is new information at the same time. A possible information display system can be provided.

(Embodiment 4)
FIG. 5 shows a block diagram of an information display system according to the second embodiment of the present invention. In FIG. 5, reference numeral 501 denotes a next information acquisition timing quantization calculation means.

  The operation and action of the information display system configured as shown in FIG. 5 are basically the same as the method of specifying the time interval at the next information acquisition timing of the second embodiment described with reference to FIG. The difference from the second embodiment is the calculation method of the next information acquisition timing information acquired in S207.

When the server control unit 107 acquires the next information acquisition timing from the next information acquisition timing submission unit 105 in the same operation as in the second embodiment, the next information acquisition timing submission unit 105 notifies the next information acquisition timing calculation unit 301. The next information acquisition timing is calculated. The next information acquisition timing calculation means 301 is the current time when the administrator of the server 101 is instructed to calculate “scheduled time for processing new information and registering in the information storage means 103” registered in the next information acquisition timing submission means 105. The time interval used as the next information acquisition timing is calculated and returned to the next information acquisition timing submission means 105. The next information acquisition timing submitting means 105 delivers the time interval returned here to the server control means 107 as the next information acquisition timing.

  The server control unit 107 performs a time interval quantization operation on the delivered time interval using the next information acquisition timing quantization operation unit 501. The next time information acquisition timing quantization calculation means 501 has, for example, a time interval of 1 = 10 minutes, 2 = 30 minutes, 3 = 60 minutes, 4 = 120 minutes, 5 = 360 minutes, 6 = 720 minutes, 7 = 1080 minutes, 8 = 1 Conversion to a value closest to the quantized value in 8 stages of 1440 is performed. The server control means 107 determines the obtained quantized value as the time acquisition timing and sends it to the information terminal 108. The information terminal 108 connects to the server 101 using the quantized next time information acquisition timing.

  If the next information acquisition timing quantized in 8 steps is used in this way, it is possible to send 11 bits of 1440 minutes in 3 bits. In the case of a system having a very large number of information terminals 108, the burden on the server 101 and the information transmission path can be reduced by reducing the amount of information as much as possible.

  By the operation described above, it is possible to provide an information display system capable of reducing the amount of information in acquiring information acquisition timing by setting the next information acquisition timing to a quantized value.

(Embodiment 5)
FIG. 6 shows a block diagram of an information display system according to the fifth embodiment of the present invention. In FIG. 6, reference numeral 601 denotes date / time information submitting means.

  The operation and action of the information display system configured as shown in FIG. 6 will be described with reference to FIG. Here, the difference from the description of the first embodiment is only the operations of S501 to S503.

  After the server control unit 107 acquires the next information acquisition timing in S207, the server control unit 107 inquires the date / time information submitting unit 601 about the date / time information. The date / time information submitting means 601 confirms the date / time held by the server 101 and returns the date / time information to the server control means 107.

  The server control unit 107 transmits the presence / absence of new information, the next information acquisition timing, and date / time information to the information terminal 108 through the Internet 114 using the server side communication unit 106 (S502). The terminal control means 113 sets the operation date / time of the information terminal 108 using the acquired date / time information.

  As a result, the time of the information terminal can be automatically corrected, and when the time is used for the next information acquisition timing, the next information acquisition timing control can be performed using a more accurate time.

  In addition, when performing information acquisition using encrypted communication, the date / time information is acquired from the server, so encrypted communication based on authentication of the server certificate including the date / time information can be reliably performed. .

  By providing the information display system capable of aligning the operation time of the information display system by providing the date / time information to the information terminal at the next information acquisition timing acquisition by the operation as described above. Can do.

  In addition, the means described in the first to fifth embodiments include hardware resources such as a CPU (or microcomputer), a RAM, a ROM, a storage / recording device, an electric / information device including an I / O, a computer, a server, and the like. You may implement in the form of the program made to cooperate. In the case of a program, the program can be distributed / updated and installed easily by recording it on a recording medium such as magnetic media or optical media, or by distributing it using a communication line such as the Internet.

  In addition, although group information demonstrated the collective housing as an example, it is not restricted to this. For example, it is assumed to be provided as appropriate according to the user's attributes such as the area and life time zone. In addition, by setting a priority for the group information, the variation in the next information acquisition timing is reduced according to the priority (group information), a group that is updated every 60 minutes, and a group that is updated every day. It is also possible to provide it. Furthermore, the correlation between the information displayed on the information terminal and the group information can be determined, and the next information acquisition timing can be set with priority given to the group information having a strong correlation. For example, when displaying time service information of a retail store, priority is given to an area (group information) in which the retail store exists.

  As described above, in the information display system and the program according to the present invention, the information terminal and the server share the group information as the information display unit, and the server displays the group every time the information terminal comes to check whether there is new information. By designating the next information acquisition timing for each piece of information, it is possible to provide an information display system in which information terminals of the same group can confirm the presence or absence of new information at the same time.

  In this information display system, not only information is regularly distributed, such as time service information display of a retail store and road information display, by the server function of the connection destination, but also the information provision interval fluctuates due to the occurrence of an event. Applicable to easy usage.
