  By the way, the intercom system described in Patent Document 1 is transmitted to the room unit after information from the management room base unit is processed by the server. On the other hand, in the intercom system described in Patent Document 2, information is distributed to the room master unit without using a server.

  In recent years, it has been proposed to install a web browser on a housing information board (room unit, room base unit) placed in a dwelling unit, and deliver large-capacity information that can be viewed with the web browser to the housing information board. However, a housing information board equipped with a web browser is expensive. That is, to install a web browser, it is necessary to increase the memory capacity or the screen of the display device, and a high-performance processor is required to operate without a sense of incongruity. In other words, a high-performance housing information board equipped with a web browser increases the cost required for hardware resources.

  Residents of high-priced dwelling units in collective housing are thought to be willing to adopt high-performance housing information panels. However, it is considered that the residents in the general price range are satisfied with the general information housing information board. Therefore, it can be said that it is desirable to mix a high-performance housing information board and a general-performance housing information board. However, in the technologies described in Patent Documents 1 and 2, it is not assumed that housing information panels having different specifications are used in a mixed manner.

  It is an object of the present invention to provide an information distribution system that allows a housing information board equipped with a web browser and a housing information board not equipped with a web browser to be mixed, and to provide an information delivery server and program. With the goal.

  In this information distribution system, the storage means includes an information panel side storage unit built in the second house information panel, and a storage medium that is detachably attached to the second house information panel, and the information distribution server includes: The second housing has a function of selecting a state of providing information from the information providing processing unit to the second housing information panel and a state of transmitting information from the information transmitting processing unit to the second housing information panel. The information board preferably includes a storage destination selection unit that selects a storage destination of information acquired from the information distribution server from the information panel side storage unit and the storage medium.

  An information distribution server according to the present invention includes a first housing information board equipped with a web browser for browsing distributed information, and a second storage means for storing information distributed without a web browser. An information distribution server for distributing acquired information to a housing information board through a local communication network, a server-side storage unit for storing the acquired information, and information stored in the server-side storage unit as a function of a web browser An information provision processing unit that processes the information into a form that can be browsed using at least the first housing information board, and an information transmission processing unit that distributes the acquired information to at least the second housing information board. Features.

  A program according to the present invention includes a first housing information board equipped with a web browser for browsing distributed information and a storage means for storing information distributed without a web browser. An information distribution server for distributing the acquired information to the home information panel of the server through the local communication network, the server-side storage unit storing the acquired information, and the information stored in the server-side storage unit of the web browser An information provision processing unit that processes the information into a form that can be browsed using a function and provides it to at least the first housing information panel, and an information transmission processing unit that distributes the acquired information to at least the second housing information panel It functions as an information distribution server.

  According to the structure of this invention, there exists an advantage that it becomes possible to use together the housing information board which mounts a web browser, and the housing information board which does not mount a web browser.

It is a block diagram which shows embodiment. It is a figure which shows the example of a display same as the above. It is operation | movement explanatory drawing same as the above.

  In this embodiment, as shown in FIG. 1, the housing information panels 2A and 2B arranged for each unit of the apartment house, the common entrance handset 3 arranged at the common entrance of the apartment house, and the management room are arranged. A configuration example in which the management apparatus 4 communicates with the management apparatus 4 through the local communication network 6 laid in the building of the apartment house. A system control device 5 is connected to the local communication network 6, and the information distribution server 1 is arranged between the management device 4 and the system control device 5. The local communication network 6 is constructed so as to perform digital communication, and a wired communication path and a wireless communication path are appropriately used.

  The general performance housing information board 2B is a conventional product used in an apartment house, and has a relatively low processing capacity of a processor and a relatively small memory capacity, and a display device such as a liquid crystal display. Means a product with a relatively small screen size. For the display device of the house information board 2B, for example, a display having a screen size of about 3.5 inches is used. The program mounted on the house information board 2B has a function necessary for communicating with the common entrance handset 3 and the management device 4. However, since the housing information board 2B controls manufacturing costs, there are restrictions on hardware resources (especially memory capacity and screen size of the display device), and highly functional application software such as a web browser is executed. Can not.

  On the other hand, the high-performance housing information panel 2A is equipped with a processor with high processing capacity, although it is expensive, has a relatively large memory capacity, and a relatively large screen size of the display device. For example, a display having a screen size of about 5 to 7 inches is used for the display device of the house information board 2A. That is, the house information board 2A includes hardware resources capable of executing high-functional application software such as a web browser.

  In the following description, it is assumed that the home information board 2A on which the web browser is installed and the home information board 2B on which the web browser is not installed are connected to the local area communication network 6. This type of usage is adopted to differentiate the dwelling units by, for example, installing the housing information panel 2B in the average price range dwelling unit and installing the housing information panel 2A in the expensive dwelling unit in the apartment house. The

  As shown in the figure, the system control device 5 communicates with the housing information panels 2A and 2B through the first communication path 61 of the local communication network 6 and the second communication path 62 of the local communication network 6. It communicates with the common entrance cordless handset 3 through. Further, the system control device 5 communicates with the management device 4 through the third communication path 63 in the local communication network 6.

  The system control device 5 is provided with a terminal T51 to which the first communication path 61 is connected, a terminal T52 to which the second communication path 62 is connected, and a connector T53 to which the third communication path 63 is connected. It is done. The physical layer of the communication protocol is different between the first communication path 61, the second communication path 62, and the third communication path 63. That is, the first communication path 61, the second communication path 62, and the third communication path 63 are not directly connected to each other, and can communicate only through the system control device 5.

  Specifically, a signal subjected to digital modulation such as OFDM (Orthogonal Frequency-Division Multiplexing) is used as a communication signal passing through the first communication path 61 and the second communication path 62. The third communication path 63 transmits a baseband signal using a communication protocol compliant with IEEE802.3. Therefore, the system control device 5 converts the communication protocol or performs routing so that the first communication path 61, the second communication path 62, and the third communication path 63 can communicate with each other. Has the ability to go. The configuration of the system control device 5 will be described later.

  As described above, the local area communication network 6 is constructed so as to perform digital communication, and actually performs communication by transmitting packets in a time division multiplex transmission system. Accordingly, the local area network 6 can transmit a plurality of types of information in parallel, and as a result, the time from the generation of information to the arrival is averaged regardless of the type of information. Information transmitted through the local communication network 6 includes voice information, image information, character information, control information, and the like. Hereinafter, a packet including audio information is referred to as an audio packet, a packet including image information is referred to as an image packet, a packet including character information is referred to as a character packet, and a packet including control information is referred to as a control packet. The control information includes call information from the common entrance handset 3 and notification information from the management device 4.

  The management device 4 is realized, for example, by executing an appropriate program on a general-purpose device such as a personal computer. However, the management device 4 may be configured as a dedicated device. The management device 4 has a function of generating character information and control information to be notified to the occupants of the housing complex and distributing them to the housing information boards 2A and 2B.

  The management device 4 includes a connector T41 to which the third communication path 63 is connected, and also includes a connector T42 for connecting an external device such as a scanner. The management device 4 includes a control unit 40 having a processor as a main component, and operates according to a program stored in the storage unit 45. The control unit 40 is connected to the connector T41 via the communication interface circuit 41, and is connected to the connector T42 via the external device interface circuit 42. Further, the management device 4 is provided with an operation device 43 such as a keyboard and a mouse and a display device 44 such as a liquid crystal display.

  When a scanner is connected as an external device of the management apparatus 4, image information read by the scanner can be transmitted to the house information panels 2A and 2B. In this case, the management device 4 can process the image information read by the scanner, and can add a comment based on character information to the image information. It is also possible to connect the management device 4 to a public network such as the Internet and distribute image information and text information acquired from a server outside the apartment house to the housing information panels 2A and 2B through the public network.

  The common entrance cordless handset 3 includes a connector T31 to which the second communication path 62 is connected. The common entrance cordless handset 3 includes a control unit 30 having a processor as a main component, and operates according to a program stored in the storage unit 36. The control unit 40 is connected to the connector T31 via the trunk transmission interface circuit 31. Further, the common entrance handset 3 includes an operation device 32 such as a numeric keypad operated by a resident or a visitor of an apartment house, a call device 33 for a visitor to call the housing information panels 2A and 2B, and a common entrance. And an image pickup device 34 for picking up the image. Furthermore, the common entrance cordless handset 3 of the example of illustration is provided with the indicator lamp 35 using a light emitting diode.

  When the operation device 32 is operated by a visitor to specify the housing information panels 2A and 2B and a calling signal (actually, a control packet including calling information) is transmitted, the housing information panels 2A and 2B that have received the calling signal. Receives an image packet corresponding to the image of the visitor imaged by the imaging device 34 and displays it on the display device 25 (described later). In addition, the home information panels 2A and 2B that have received the calling signal can select whether or not to make a call with the visitor using the operation device 26 (described later). That is, the resident of the dwelling unit in which the housing information panels 2A and 2B that have received the calling signal confirm the visitors displayed on the housing information panels 2A and 2B, and then determine whether or not to call the visitors. The operation to select becomes possible.

  The housing information panels 2A and 2B include a connector T21 to which the first communication path 61 is connected, and a connector T22 for connecting a dwelling unit (not shown) arranged beside the door of each dwelling unit. The house information boards 2A and 2B include a control unit 20 having a processor as a main component, and operate according to a program stored in the information board side storage unit 27 built in the house information boards 2A and 2B. The control unit 20 is connected to the connector T21 via the trunk line transmission interface circuit 21, and is connected to the connector T22 via the dwelling unit interface circuit 22. The home information boards 2A and 2B are provided with a voice input / output device 23 for inputting / outputting a voice, a display lamp 24 using a light emitting diode, a display device 25 for displaying an image, and an operation device 26 such as a touch panel. It is done. The voice input / output device 23 includes a microphone and a speaker, and is mainly used for a resident of a dwelling unit to talk with a visitor between the common entrance cordless handset 3 and the dwelling unit. The voice input / output device 23 may be configured as a handset, or may be configured to enable a hands-free call. The voice input / output device 23 also has a function of outputting a notification sound for notifying a resident that a call signal has been received from the common entrance handset 3.

  The display device 25 includes a display device such as a liquid crystal display device. When the housing information panels 2A and 2B receive an image (that is, an image packet) from the common entrance handset 3, the display device 25 displays an image of the common entrance. The operation device 26 is assumed to be a touch panel in which a touch switch is superimposed on the display screen. However, as the operation device 26, a switch that mechanically opens and closes a contact may be used, or a touch panel and a switch may be used in combination. . When the occupant operates the operation device 26, an instruction operation is performed on the house information panels 2A and 2B.

  The control unit 20 functions as a data conversion unit 201 that causes character information to be presented to at least one of the voice input / output device 23 and the display device 25 when character information is received from another device. Although the data conversion unit 201 can convert character information into audio data, the following description assumes that the data conversion unit 201 converts character information into image data to be presented on the display device 25.

  As described above, the house information board 2A and the house information board 2B have different screen sizes of the display device 25 and different capacities of memories constituting the information board-side storage unit 27. Processing capacity is also different. Therefore, the application program executable by the processor is different between the house information board 2A and the house information board 2B. The house information board 2A has a web browser function, but the house information board 2B has a web browser. The function of is not installed.

  The system control device 5 includes a control unit 50 having a processor as a main component, and operates according to a program stored in the storage unit 54. The control unit 50 is connected to the terminal T51 through the first communication interface unit 51, is connected to the terminal T52 through the second communication interface unit 52, and is connected to the connector T53 through the third communication interface unit 53. Connected.

  The control unit 50 has a function of a packet multiplexing unit 501 that assembles and transmits packets through the first communication path 61, the second communication path 62, and the third communication path 63. The packet multiplexing unit 501 also has a function of performing communication protocol conversion and routing described above.

  As described above, since the first communication interface unit 51, the second communication interface unit 52, and the third communication interface unit 53 have different physical layers, they can transmit packets in parallel. Is possible.

  For example, while the common entrance cordless handset 3 is making a call with the housing information panels 2A and 2B, information such as communication items transmitted to the housing information panels 2A and 2B is generated in the management device 4. Consider the case. In this case, the packet multiplexing unit 501 includes information to be transmitted from the management device 4 to the housing information panels 2A and 2B in the voice packet and the image packet transmitted from the common entrance cordless handset 3 to the housing information panels 2A and 2B. Multiplex packets. Therefore, the house information boards 2A and 2B can receive a packet including information from the management device 4 while making a call with the common entrance handset 3.

  In other words, the house information boards 2A and 2B can receive the information from the management device 4 without delay while talking with the common entrance handset 3. Therefore, the management device 4 does not need to wait for the call on the home information boards 2A and 2B to end when distributing information to the home information boards 2A and 2B. As a result, the management device 4 can always distribute information.

  By the way, since the display device 25 provided in the housing information panel 2A is relatively large such as about 5 to 7 inches, even if information of the size of about A4 size is displayed on one screen of the display device 25, the display device 25 is almost entirely. Can be read. On the other hand, the display device 25 provided on the home information board 2B is limited in size to about 3.5 inches. Therefore, when information on the size of about A4 size is displayed on one screen of the display device 25, the details can be read. It is difficult. That is, the housing information board 2B has a problem that information visibility is low. This problem can be solved by providing the display device 25 with a function for enlarging and displaying a part of the image information. However, since the communication items do not fit within one screen, the information listability is lowered.

  On the other hand, visibility and listability can be improved by transmitting information such as communication items as character information to the housing information board 2B. In addition, if the font used for character information is an outline font, it can be easily enlarged and reduced, and is not bitmap image information. Therefore, the character size is reduced to increase the amount of information displayed on one screen. However, visibility can be maintained. Alternatively, it is possible to increase the visibility of an elderly person with reduced visual acuity by enlarging the character size.

  The information distributed from the management device 4 to the housing information panels 2A and 2B includes the type of garbage (combustible waste, recyclable waste, plastic, etc.), the collection date and time zone, and the date of cleaning and inspection. , The date and time of drug spraying. In addition, the date and place of the meeting, the date and place of the event, the conference report of the residents' association, the notifications from the police and fire department, etc. are also distributed to the housing information boards 2A and 2B. Below, the matter delivered from the management device 4 to the house information panels 2A and 2B is called “event”, and the event information will be described as including the date and time when the event is performed.

  As described above, since only the character information can be displayed on the house information board 2B, the event is displayed on the display device 25 of the house information board 2B, for example, in the form of FIG. On the other hand, since the house information board 2A can display not only character information but also image information, the display device 25 of the house information board 2A can display events in a calendar format as shown in FIG. 2A, for example. Is possible. Here, the information distributed from the management device 4 to the house information boards 2A and 2B is delivered to the house information boards 2A and 2B through the information delivery server 1. That is, the information distribution server 1 has a function of processing the character information and the image information described above according to the functions of the house information panels 2A and 2B that distribute information.

  As shown in FIG. 1, the information distribution server 1 is inserted between the management device 4 and the system control device 5. That is, the information distribution server 1 is inserted in the third transmission path 63. Therefore, the information distribution server 1 includes a connector T11 to which the management apparatus 4 is connected via the third transmission path 63 and a connector T12 to which the system control apparatus 5 is connected via the third transmission path 63. Prepare. Furthermore, the information distribution server 1 includes a control unit 10 having a processor as a main component, and operates according to a program stored in the server-side storage unit 13. The control unit 10 is connected to the connector T11 via the communication interface unit 11, and is connected to the connector T12 via the communication interface unit 12. Furthermore, the control part 10 is provided with the function to preserve | save in the server side memory | storage part 13, if the information delivered to the house information boards 2A and 2B from the management apparatus 4 through the communication interface part 11 is received.

  The information distributed from the management device 4 to the home information boards 2A and 2B is mainly text information, but also includes image information created by reading with a scanner. The image information is distributed in a format such as JPEG, GIF, or PDF, and is enlarged and displayed on the house information boards 2A and 2B as necessary. In the following, a configuration for handling character information will be described without particularly describing image information.

  As described above, the housing information board 2A can display information with a large amount of information such as a calendar format, and the housing information board 2B can display text information with a small amount of information. In order to correspond to the housing information panels 2A and 2B having different functions as described above, the control unit 10 includes an information provision processing unit 101 and an information transmission processing unit 102.

  The information provision processing unit 101 processes the character information stored in the server-side storage unit 13 into a format (HTML or the like) that can be browsed using the function of the web browser installed in the housing information board 2A, and is a push type Information is provided to the housing information board 2A by the service. For example, when displaying an event on the display device 25 of the house information board 2A in the calendar format described above, the information providing processing unit 101 delivers information at an appropriate timing, and the information delivered by the web browser of the house information board 2A is displayed. indicate. Further, when a desired item is selected by the operation device 26 from an event represented in a calendar format, detailed character information regarding the item is displayed on the display device 25.

  In the above-described example, the operation in the case where the information providing processing unit 101 provides the push type service and the housing information panel 2A can receive the push type service is shown. In response to this, the information distribution server 1 notifies the housing information board 2A only that new character information has been generated, and in response to this notification, the pull that causes the housing information board 2A to access the information distribution server 1 A mold service may be provided.

  On the other hand, the information transmission processing unit 102 transmits the character information received from the management device 4 toward the house information board 2B. That is, when receiving the character information from the management device 4, the information distribution server 1 delivers it to the information transmission processing unit 102 and distributes it to the house information board 2B. The housing information board 2B temporarily stores the information received from the information transmission processing unit 102 of the information distribution server 1 in the information board side storage unit 27, reads the information from the information board side storage unit 27, and displays it on the display device 25.

  The information distribution server 1 stores the information acquired from the management device 4 in the server-side storage unit 13 and processes it by the information provision processing unit 101 according to whether the information is distributed to the house information panel 2A or the house information panel 2B. Or transmission through the information transmission processing unit 102 is selected. However, this operation is an example, and one of the information provision processing unit 101 and the information transmission processing unit 102 may be selected according to the content of information and the capacity of information regardless of the information delivery destination. Alternatively, the acquired information can be distributed to the housing information boards 2A and 2B through both the information provision processing unit 101 and the information transmission processing unit 102. Even if information is provided from the information provision processing unit 101 to the housing information board 2B, the information cannot be browsed on the housing information board 2B. However, as will be described later, a separate storage medium is attached to the housing information board 2B. Information can be viewed on the device.

  Information transmitted from the management device 4 to the housing information panels 2A and 2B is multiplexed together with the voice packet, the image packet, and the control packet in the system control device 5, and the processing described above in the housing information panels 2A and 2B. Is displayed on the display device 25.

  With the configuration described above, a high-performance housing information board 2A capable of executing application software such as a web browser and a general-performance housing information board 2B that cannot be equipped with a web browser are mixed in the local area communication network 6. be able to. For this reason, if the prices of apartment units in apartment buildings are differentiated, high-performance housing information panels 2A should be installed in luxury properties, and general-performance housing information panels 2B in regular properties. This makes it possible to differentiate residential units for convenience. That is, since the information distribution function can be differentiated according to the price of the property, it is possible to flexibly respond to customer needs. In addition, since digital communication is performed, it is possible to mix a call function and an information distribution function.

  In the above configuration, when the information distribution server 1 distributes the information received from the management device 4 to the house information board 2 </ b> A, the information is stored in the server-side storage unit 13. Therefore, if the storage area of the server-side storage unit 13 is increased, it is possible to deal with cases where the number of information items to be distributed is large or the information capacity is large. Moreover, since the high-performance housing information board 2A is equipped with a web browser and functions as a client of the information distribution server 1, it is not necessary to store a large amount of information in the housing information board 2A. That is, it is necessary to store a large number of information or a large amount of information in the server information storage server 13 of the information distribution server 1 so that the housing information board 2A stores a large number of information or a large amount of information. Absent.

  Since the home information board 2A is equipped with a web browser, if the information distribution server 1 is connected to the Internet, the home information board 2A is used to receive information from an external server provided on the Internet. You may get it. However, it is desirable that an information security function is added to the information distribution server 1 so that unauthorized access through the Internet is prevented. Furthermore, the management apparatus 4 may be connected to the Internet, image information and text information may be acquired from an external server provided on the Internet, and information may be distributed to the housing information boards 2A and 2B.

  By the way, the general performance housing information board 2 </ b> B cannot be equipped with a web browser, and information such as image information and character information distributed from the management apparatus 4 is stored in the information board side storage unit 27. For this reason, the number of pieces of information that can be stored in the information board side storage unit 27 of the house information board 2B and the capacity of the information are limited.

  Therefore, the housing information board 2B preferably includes an external storage medium interface 28 for detachably connecting a storage medium made of a semiconductor memory, as indicated by a broken line in FIG. The storage medium connected to the external storage medium interface 28 may be configured using a semiconductor memory, as long as it is detachable and rewritable with respect to the house information board 2B. Examples of this type of storage medium include an SD memory card, a micro SD memory card, and a USB memory. Therefore, the external storage medium interface 28 is realized by a memory card connector or a USB connector.

  When the housing information board 2B includes the external storage medium interface 28 and the storage medium is attached to the external storage medium interface 28, the housing information board 2B receives the push-type service in the same manner as the housing information board 2A. It is good also as a structure. When the house information board 2B is configured to support push-type service, the control unit 20 of the house information board 2B is connected to the external storage medium interface 28 as the storage destination of the information delivered from the information delivery server 1. The external storage or the server-side storage unit 13 is selected.

  That is, the control unit 20 stores the character information in which the received information is described in normal text in the information board side storage unit 27 and connects the information in which the received information is described in HTML or the like to the external storage medium interface 28. A storage destination selection unit 202 for storing in the storage medium. That is, the storage destination selection unit 202 distributes and stores the information acquired by the house information board 2B from the information distribution server 1 between the information board side storage unit 27 and the storage medium. Rules for allocating information storage destinations can be set as appropriate. If the capacity exceeds the specified value or the number of cases exceeds the specified value even for normal text (character information), external storage It may be stored in a storage medium connected to the medium interface 28.

  As described above, the housing information board 2B stores information by distributing it to the server-side storage unit 13 and the storage medium based on the description format, capacity, number of cases, and the like of the information received from the information distribution server 1. From the distribution server 1, it can be handled in the same manner as the housing information board 2A. That is, the information distribution server 1 can distribute information without distinguishing between the house information board 2A and the house information board 2B.

  However, since the home information board 2A is equipped with a web browser, it can handle the pull type service. However, since the house information board 2B does not have a web browser, it cannot support the pull type service building. Moreover, since the house information board 2B does not have a web browser, the received information cannot be displayed on the display device 25 of the house information board 2B even if it is a push type service. In this case, the storage medium connected to the external storage medium interface 28 is removed, and the contents of the storage medium are read by another device (for example, a personal computer).

  In the above configuration example, the external storage medium interface 28 is provided only on the house information board 2B. However, the external information storage medium interface 28 may be provided on the house information board 2A so as to function in the same manner as the house information board 2B. . However, the rule for distributing information in the house information board 2A may be different from the rule for distributing information in the house information board 2B.

  Further, when both the server-side storage unit 13 and the external storage medium interface 28 are provided, the distributed information may be stored in both the server-side storage unit 13 and the storage medium. Thus, by storing information in two places, even if one information is lost, backup can be performed by the other.

  By the way, since the system control device 5 is interposed between the management device 4 and the housing information panels 2A and 2B, when the management device 4 distributes information to the housing information panels 2A and 2B, the management device 4 has the housing. Whether the information has reached the information panels 2A and 2B cannot be confirmed directly from the housing information panels 2A and 2B. Therefore, the system control device 5 includes a distribution management processing unit 502 that confirms whether or not the information from the management device 4 has reached the housing information panels 2A and 2B. In the illustrated example, the control unit 50 functions as the distribution management processing unit 502. The distribution management processing unit 502 notifies the management device 4 of the completion of information distribution when the distribution of information to the housing information panels 2A and 2B is completed. When distributing information from the management device 4 to a plurality of housing information panels 2A and 2B, the distribution management processing unit 502 has completed distribution of information to all the housing information panels 2A and 2B that are the distribution targets. At this point, the management apparatus 4 is notified of completion.

  A specific example will be described. As shown in FIG. 3, the management device 4 inputs data for distribution from an external device such as a scanner, or inputs data for distribution by operating the operation device 43, and distributes the data to the system control device 5. Request. The system control device 5 stores the data for distribution received from the management device 4 in the information panel side storage unit 27, and then distributes the data to the required house information panels 2A and 2B. Multicast communication is performed when data is distributed to a plurality of housing information panels 2A and 2B. The house information boards 2A and 2B are provided with an information board side storage unit 27 (see FIG. 1), and store data received from the system control device 5 in the information board side storage unit 27.

  The system control device 5 confirms the delivery of data for each of the housing information panels 2A and 2B after distributing the data to the housing information panels 2A and 2B by multicast communication. When the delivery of data is confirmed to all the housing information panels 2A, 2B, the system control device 5 notifies the management device 4 that the data distribution has been completed.
