  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 51 and the second communication path 52. The third communication path 53 transmits a baseband signal using a communication protocol compliant with IEEE802.3. Therefore, the system control device 1 converts the communication protocol or performs routing so that the first communication path 51, the second communication path 52, and the third communication path 53 can communicate with each other. Has the ability to go. The configuration of the system control device 1 will be described later.

  As described above, the local area communication network 5 is constructed to perform digital communication, and actually performs communication by transmitting packets in a time division multiplex transmission system. Therefore, the local area communication network 5 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 5 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 resident of the apartment house and distributing it to the house information board 2.

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 an external server to the house information board 2 through the public network. Further, the management apparatus 4 may have a server function, and the house information board 2 may be used as a client of the management apparatus 4 for communication.

  The common entrance cordless handset 3 includes a connector T31 to which the second communication path 52 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. In addition, 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 talk to the housing information board 2, and an image of a common entrance. And an image pickup device 34 for picking up images. 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 and the house information board 2 is specified and a call signal (actually, a control packet including call information) is transmitted, the house information board 2 that has received the call signal receives an image pickup device. An image packet corresponding to the image of the visitor 34 is received and displayed on the display device 25 (described later). In addition, the house information panel 2 that has received the calling signal can select whether to make a call with the visitor using the operation device 26 (described later). That is, the resident of the dwelling unit where the house information board 2 receiving the call signal confirms the visitor displayed on the house information board 2 and then selects whether or not to make a call with the visitor. It becomes possible.

  The house information panel 2 includes a connector T21 to which the first communication path 51 is connected, and a connector T22 for connecting a dwelling unit (not shown) arranged beside the door of each dwelling unit. The house information board 2 includes a control unit 20 having a processor as a main component, and operates according to a program stored in the storage unit 27. 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 board 2 is 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. 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 such as a liquid crystal display. When the housing information board 2 receives 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 for the house information panel 2 is performed.

  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.

  The system control device 1 includes a terminal T11 to which the first communication path 51 is connected, a terminal T12 to which the second communication path 52 is connected, and a connector T13 to which the third communication path 53 is connected. Yes. Further, the system control apparatus 1 includes a control unit 10 having a processor as a main component, and operates according to a program stored in the storage unit 15. The control unit 10 is connected to the terminal T11 through the first communication interface unit 11, is connected to the terminal T12 through the second communication interface unit 12, and is connected to the connector T13 through the third communication interface unit 13. Connected.

  The control unit 10 includes a function of the packet multiplexing unit 101 that assembles and transmits a packet through the first communication path 51, the second communication path 52, and the third communication path 53. The packet multiplexing unit 101 also has a function of performing communication protocol conversion and routing described above.

As described above, the first communication interface unit 11 and the second communication interface unit 12 and the third communication interface unit 13, it is possible to transmit packets with the same time in parallel. For example, let us consider a case where character information to be transmitted to the house information board 2 is generated in the management device 4 while the common entrance handset 3 is making a call with the house information board 2. In this case, the packet multiplexing unit 101 multiplexes the character packet transmitted from the management device 4 to the housing information panel 2 into the voice packet and the image packet transmitted from the common entrance handset 3 to the housing information panel 2. Therefore, the house information board 2 can receive the character packet from the management device 4 while making a call with the common entrance handset 3.

  In other words, the house information board 2 can receive the character 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 house information board 2 to end when distributing information such as communication items to the house information board 2. As a result, the management device 4 can always distribute information.

  By the way, since the display device 25 provided in the house information panel 2 is limited in size to about 3.5 inches, it may be used for identifying a visitor from the image information transmitted from the joint entrance 3. Can be used. However, it is difficult to read details when information of the size of about A4 size is displayed on one screen of the display device 25. That is, there arises a problem that information visibility is lowered. 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 listability of information is deteriorated. .

  On the other hand, since it is possible to transmit character information from the management device 4 to the house information board 2, visibility and listability can be improved by transmitting communication items and the like as character information. . In addition, if the font used for character information is an outline font, it can be easily enlarged or reduced, and the character size is reduced in order to increase the amount of information displayed on one screen as compared to bitmap image information. Even if visibility is secured. In addition, for an elderly person who has decreased visual acuity, visibility can be improved by enlarging the size of characters.

  In addition, contents to be distributed as text information from the management device 4 to the housing information board 2 include the type of garbage related to garbage collection (combustible garbage, recyclable garbage, plastic, etc.), collection date and time, cleaning and inspection. There are date and time, date and time of drug application. 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 board 2. Below, the matter delivered from the management device 4 to the house information board 2 is called “event”, and the description will be made assuming that the date and time when the event is executed is included in the contact matter. FIG. 2 shows a display example of the event on the display device 25 of the house information panel 2.

  In order to transmit character information from the management device 4 to the housing information board 2, the system control device 1 multiplexes the character packets together with voice packets, image packets, and control packets, and the housing information board 2 supports the character packets. It is only necessary to enable processing to be performed. Therefore, there is no need to provide a separate server, and an increase in cost can be suppressed.

By the way, since the system control device 1 is interposed between the management device 4 and the house information board 2, when the information is delivered from the management device 4 to the house information board 2, the management device 4 moves to the house information board 2. Whether the information has arrived cannot be confirmed directly from the housing information board 2. Therefore, the system control device 1 includes a distribution confirmation processing unit 102 that confirms whether information from the management device 4 has reached the house information board 2. In the illustrated example, the control unit 10 functions as the delivery confirmation processing unit 102. The delivery confirmation processing unit 102 notifies the management device 4 of the completion of information delivery when the delivery of information to the house information board 2 is completed. When distributing information from the management device 4 to a plurality of housing information panels 2, the distribution confirmation processing unit 102 manages the management device when the distribution of information to all the housing information panels 2 as distribution targets is completed. 4 is notified of completion.

The management device 4 includes a power supply output control circuit 46 that prohibits power-off until a notification of distribution completion is received from the distribution confirmation processing unit 102. If the power is turned off without waiting for the completion of the information distribution after the management device 4 sends the information distributed to the house information board 2, the information is not retransmitted, and as a result, part of the house information board 2 Or, there is a possibility that information is not distributed in all. In order to avoid such a situation, the management device 4 is configured to turn off the power supply during a period until the notification of the completion of distribution is obtained from the system control device 1 after distributing the information to the housing information panel 2. It is prohibited by the output control circuit 46. Notification of the completion of distribution from the system control apparatus 1 to the management apparatus 4 is performed using the third communication interface unit 13.

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 1. Request. The system control device 1 stores the distribution data received from the management device 4 in the storage unit 15, and then distributes the data to the required house information board 2. When data is distributed to a plurality of housing information panels 2, multicast communication is performed. As described below, housing information panel 2 is provided with a storage unit 27 (see FIG. 1), stores the data received system controller 1 or found in the storage unit 27.

The system control device 1 confirms delivery of data for each house information board 2 after distributing the data to the house information board 2 by multicast communication. During this time, the power supply of the management device 4 is prohibited from being shut off. When the delivery of data is confirmed to all the house information panels 2, the system control device 1 notifies the management device 4 that the data delivery is completed. Management apparatus 4 permits when receiving the notification of the system controller 1 or these distribution completion, the stop of power supply from the power source output control circuit 46 to an internal circuit of the control apparatus 4.

  The operation described above prevents the power supply of the management apparatus 4 from being shut off when the distribution of information from the management apparatus 4 to the house information panel 2 is not completed. Therefore, at the time when the operator of the management device 4 such as the manager of the apartment house finishes the information distribution operation, the operator recognizes that the information distribution is completed, but the house information panel 2 This prevents the situation where the distributed information has not been received.

In the above-described operation, the distribution confirmation processing unit 102 is provided in the system control device 1 to confirm the completion of information distribution to the house information panel 2. In the power output control circuit 46 provided in the management device 4, A configuration may be adopted in which the power supply is prohibited from being interrupted for a certain waiting time from the start of information distribution. In this case, the delivery confirmation processing unit 102 can be omitted from the system control device 1.

Further, even when the delivery confirmation processing unit 102 is provided in the system control apparatus 1, a function of controlling by the standby time may be added to the power output control circuit 46. For example, when the information delivery completion cannot be notified to the management apparatus 4 due to an abnormality in the system control apparatus 1, the management apparatus 4 may be configured to be able to shut off the power when the standby time expires. With this configuration, it is possible to prevent a situation in which the power source of the management device 4 cannot be shut off. The waiting time is set to be slightly longer than the expected time until the information distribution is completed in consideration of the time when the information distribution is completed.

As described above, the control unit 40 is provided with the function of the notification unit 401 to indicate that the power supply output control circuit 46 prohibits the power supply cutoff in the management device 4 during the period when the power supply output control circuit 46 prohibits the power supply cutoff. May be. Prohibiting the power-off is equivalent to distributing information from the management device 4 to the house information panel 2, so that the notification unit 401 notifies the operator of the management device 4. Either of the meanings of prohibition of power-off and information distribution may be notified. The notification unit 401 performs the notification by displaying a message on the screen of a display provided in the management device 4. In addition, the notification unit 401 can appropriately adopt a configuration that performs auditory notification using a speaker provided in the management device 4, a configuration that performs visual notification using an indicator lamp provided in the management device 4, and the like. It is.

  As described above, in order to distribute character information from the management device 4 to the house information board 2, the house information board 2 has a configuration for handling character information. Below, the technique for improving the convenience when handling character information in the housing information board 2 will be described. The house information board 2 stores character information and has a function of automatically performing “delete”, “update”, and “select” operations on the stored character information. “Delete” means that character information that is estimated to be unnecessary from the stored character information is automatically deleted. “Update” means that when character information for updating stored character information is received, it is automatically updated. “Select” means a function of selecting and presenting necessary information from stored character information.

  In order to realize these functions, the house information board 2 has a function of extracting the character information from the character packet received through the trunk transmission interface circuit 21 in the control unit 20. The control unit 20 extracts information corresponding to the packet according to the type of the packet received through the trunk transmission interface circuit 21, and restores the information transmitted after being divided into a plurality of packets to the original information. Is provided. That is, the control unit 20 extracts voice information from the voice packet, extracts image information from the image packet, extracts character information from the character packet, and extracts control information from the control packet.

  The storage unit 27 provided in the house information board 2 has a function of storing character information extracted from the character packet by the control unit 20. The storage unit 27 stores each piece of character information as one file. For example, the communication item notified as character information from the management device 4 is a group of character information, and one communication item is stored in the storage unit 27 as one file.

  The “delete” operation means that any one of the files stored in the storage unit 27 is automatically deleted when a predetermined condition is satisfied. In order to realize the “deletion” function, the control unit 20 includes a date and time extraction unit 202 that extracts a part indicating the date and time corresponding to the expiration date of the character information from the character information, as shown in FIG.

  For example, the character information of the event distributed to the house information board 2 includes the date and time of the event, but when this date and time passes, the character information becomes unnecessary. That is, this type of character information has a date and time corresponding to the expiration date. When character information whose execution date and time (hereinafter referred to as “expiration date”) has passed is automatically deleted from the storage unit 27, the storage unit 27 of the housing information panel 2 with limited capacity is effectively used. Become.

  Character information having an expiration date is described so that a portion indicating the expiration date in the character information can be distinguished from other portions. The technology that distinguishes the character string indicating the expiration date from other parts includes a technology that standardizes the character string format or fixes the position, and a technology that inserts a reserved character at least before or after the character string. And a technique for inserting invisible control characters at least one of the front and rear of the character string. The invisible control character is a character that is included in the character information but is not displayed on the display device 25 and is used to indicate the position of the date and time.

  The date and time extraction unit 202 determines whether or not the character information handled as one file includes a date and time indicating the expiration date. If the date and time information includes the date and time indicating the expiration date, a date (character string) indicating the date and time is displayed. Extract from text information. The target for extracting the expiration date in the “delete” operation is the character information (file) stored in the storage unit 27, and the expiration date of the character information stored in the storage unit 27 is past with respect to the current date and time. If it is the date and time, the character information is deemed unnecessary and is deleted from the storage unit 27.

  The current date and time is counted by the clock unit 28 (see FIG. 1) provided in the house information panel 2. The control unit 20 also has a function as a comparison unit 203 that compares the expiration date and time extracted by the date and time extraction unit 202 from the character information stored in the storage unit 27 with the current date and time counted by the clock unit 28. Further, the control unit 20 also functions as a data management unit 204 that deletes the corresponding character information from the storage unit 27 when the comparison result of the comparison unit 203 satisfies the condition. That is, when the expiration date / time is a past date / time with respect to the current date / time, the comparison unit 203 performs data management on the name of the character information having the expiration date (that is, the file name) together with the instruction “delete”. Notification to the unit 204. When the date and time extracted by the date and time extraction unit 202 is past from the current date and time counted by the clock unit 28 and “deletion” is notified from the comparison unit 203, the data management unit 204 notifies the corresponding character. The information is deleted from the storage unit 27.

  The timing at which the date and time of the expiration date extracted from the character information stored in the storage unit 27 in the comparison unit 203 is compared with the current date and time may be set to a fixed time for each day or a fixed time for each week. Alternatively, the expiration date / time may be extracted and stored in advance from the character information stored in the storage unit 27, and the stored date / time may be compared with the current date / time at regular intervals. Alternatively, the character information that satisfies the condition may be deleted when the condition is satisfied, or may be deleted after a predetermined time has elapsed since the condition was satisfied.

  Further, since it may be inconvenient to automatically “delete” the character information stored in the storage unit 27, the housing information board 2 is effective in the operation of automatically “deleting” the character information. It may be possible to select invalid. When the character information stored in the storage unit 27 is not automatically “deleted”, the character information “deleted” is performed by performing an instruction operation on the house information panel 2, from another device such as the management device 4. A configuration in which the character information is “deleted” by the communication may be adopted. If character information stored in the storage unit 27 is not automatically “deleted”, past character information can be confirmed.

  Since the data management unit 204 automatically deletes the corresponding character information file from the storage unit 27 when the character information used for event notification has expired, the data management unit 204 manually deletes the character information. This saves time and effort. Further, since unnecessary information is deleted from the storage unit 27, the storage unit 27 is prevented from running out of capacity, and unnecessary character information does not remain in the storage unit 27. It becomes easy to find the desired character information from the character information.

  Character information stored in the storage unit 27 is displayed in a list on the display device 25, and necessary character information is selected by performing an instruction operation on the house information panel 2 using a touch panel or a switch. The character information stored in the storage unit 27 may be displayed on the display device 25 one by one in order by an instruction operation to the house information board 2.

  The clock unit 28 is assumed to be a real-time clock provided separately from the microcomputer constituting the control unit 20, but the current time may be measured using a counter of the microcomputer. The initial setting of the clock unit 28 may be basically performed by an instruction operation using a touch panel or a switch provided on the house information panel 2. Further, the time acquired by the management device 4 from the NTP server or the like may be acquired through communication through the system control device 1, so that the current time measured by the clock unit 28 may be automatically updated.

  Next, the “update” operation will be described. The operation of “update” is stored when any of the character information stored in the storage unit 27 and the character information newly received by the house information board 2 are estimated to be the same content or information related to the same matter. This means that the character information stored in the unit 27 is replaced with the received character information. That is, of the character information stored in the storage unit 27, the character information having the same content or the same as the newly received character information is deleted, and the newly received character information is stored in the storage unit 27.

If the above processing is possible, the character information can be easily replaced when an error is found in the character information distributed from the management device 4. That is, when character information corrected for the same matter for correcting character information is newly distributed from the management device 4, the character information distributed later is replaced with the previous character information. As a result, since only the corrected character information is stored in the storage unit 27, unnecessary information is prevented from being presented on the house information board 2 , and the storage unit 27 is not short of capacity due to useless character information. Further, since unnecessary character information does not remain in the storage unit 27, it becomes easy to find target character information from the character information stored in the storage unit 27.

  There are two types of conditions for determining that two types of character information to be compared are the same content or the same item: a condition using a date corresponding to the expiration date of the character information, and a condition using a title related to the contents of the character information. It is prepared.

  The condition using the date and time is that the date and time corresponding to the expiration date of the character information stored in the storage unit 27 matches the date and time corresponding to the expiration date of the received character information, and this condition is satisfied. The two pieces of character information are presumed to be information relating to the same content. In other words, if the communication item is an event, as described above, when the date and time of the event is the expiration date and the date and time of execution are the same, it is estimated as character information related to the same event.

  As is apparent from the above-described operation, the “update” operation is started with the reception of new character information as a trigger. When the character information is received, the date and time extraction unit 202 extracts the date and time (first date and time) corresponding to the expiration date from the received character information. The date extraction unit 202 also extracts the date (second date) corresponding to the expiration date from the character information stored in the storage unit 27. Here, the process of extracting the date and time from the character information stored in the storage unit 27 may be performed in advance before receiving the character information, and the extracted date and time may be stored separately for search. The process of extracting the date and time from the character information received by the date and time extraction unit 202 or the character information stored in the storage unit 27 is the same as in the case of “deletion”.

  The comparison unit 203 compares the date and time extracted from the received character information (first date and time) with the date and time extracted from character information stored in the storage unit 27 (second date and time). That is, the comparison unit 203 searches whether or not the character information including the second date and time that matches the first date and time is stored in the storage unit 27. Further, when character information including the second date and time that matches the first date and time is present in the storage unit 27, the comparison unit 203 performs data management on the name of the character information (that is, the file name) together with an “update” instruction. Notification to the unit 204.

  When the date and time that matches the date and time extracted from the received character information is extracted from the character information stored in the storage unit 27 and the “update” instruction is notified from the comparison unit 203, the data management unit 204 stores the date and time. The corresponding character information in the part 27 is updated. That is, the data management unit 204 replaces the character information including the second date and time that matches the first date and time in the storage unit 27 with the newly received character information.

  When a title is used instead of the date and time, a title extraction unit 205 is provided in the control unit 20 instead of the date and time extraction unit 202 as shown in FIG. The title extraction unit 205 extracts a part indicating a title related to the contents of the character information from the received character information. For example, assuming that the message is an event, the name of the event becomes the title.

  By the way, in order for the title extraction unit 205 to extract a title from character information, it is necessary to describe the character information so that the portion indicating the title in the character information can be distinguished from other portions. The technology that distinguishes the character string indicating the title from other parts includes a technology that fixes the format of the character string or fixes the position, a technology that inserts a specific character reserved at least before or after the character string, There is a technique for inserting invisible control characters in at least one of the front and rear of a character string. That is, the character information is described in a format for extracting the title, as in the case of extracting the date and time from the character information. The title extraction unit 205 extracts a part (character string) indicating a title from character information handled as one file.

  When performing “update” using a title as a condition, it is a condition that the title included in the character information stored in the storage unit 27 matches the title included in the received character information. When this condition is satisfied, the two pieces of character information are estimated to be information relating to the same content. In short, character information having the same title is estimated as character information related to the same content. For example, if the communication item is an event, if the title of the event is the same, it is presumed to be character information related to the same event.

  The “update” operation is triggered by the reception of new character information. When character information is received, the title extraction unit 205 extracts a title (first title) from the received character information. The title extraction unit 205 also extracts a title (second title) from the character information stored in the storage unit 27. The processing for extracting the title from the character information stored in the storage unit 27 may be performed in advance before receiving the character information, and the extracted title may be stored separately for search.

  The comparison unit 203 compares the first title extracted from the received character information with the second title extracted from the character information stored in the storage unit 27. That is, the comparison unit 203 searches whether or not the character information including the second title that matches the first title is stored in the storage unit 27. In addition, when character information including a second title that matches the first title exists in the storage unit 27, the comparison unit 203 performs data management on the name (that is, the file name) of the character information together with an instruction of “update”. Notification to the unit 204.

  When the title matching the title extracted from the received character information is extracted from the character information stored in the storage unit 27 and the “update” instruction is notified from the comparison unit 203, the data management unit 204 stores the title. The corresponding character information in the part 27 is updated. That is, the data management unit 204 replaces the character information including the second title that matches the first title in the storage unit 27 with the newly received character information.

  Here, when date and time is used as a condition to determine whether two text information has the same content or the same item, it is not possible to cope with a modification that changes the date and time. In this case, the title is used as a condition. It becomes possible to respond. Therefore, it is preferable that the update condition is determined using both the date and the title, and the update is performed when the condition for either the date or the title is satisfied. Alternatively, the title is preferentially used among the date and time and the title is updated, and the update is performed on condition that the titles match. The character information having the same date and time may be updated.

  By the way, in the above-described operation example, the timing when the character information stored in the storage unit 27 is close to the received character information is assumed to be when the condition is satisfied, but the time specified after the condition is satisfied It may be after elapse.

  Further, since it may be inconvenient to automatically “update” the character information stored in the storage unit 27, the housing information board 2 is effective in the operation of automatically “updating” the character information. Invalidity may be selectable. When the “update” of the character information stored in the storage unit 27 is not automatically deleted, a configuration in which the character information is “updated” by performing an instruction operation on the house information board 2, from another device such as the management device 4 A configuration in which the character information is “updated” by communication may be employed.

  Next, the “selection” operation will be described. In the “select” operation, necessary information is selected from the character information stored in the storage unit 27, and the selected character information is displayed on the housing information board 2 when the communication with the joint entrance 3 is completed. It means to do. That is, since “selection” is triggered by the end of communication (call) with the common entrance handset 3, the control unit 20 starts and ends communication with the common entrance handset 3 as shown in FIG. 6. A communication detection unit 206 for detecting When the communication detection unit 206 detects the end of communication (that is, a call) with the common entrance handset 3, the communication detection unit 206 stores the current date and time that the clock unit 28 measures at the end of the call and the storage unit 27. The comparison unit 203 is instructed to compare with the date and time corresponding to the expiration date extracted by the date and time extraction unit 202 from the character information.

  The process of extracting the date and time corresponding to the expiration date from the character information stored in the storage unit 27 by the date and time extraction unit 202 is the same as the process for “deletion” and “update”. In addition, the comparison unit 203 compares the date and time extracted from the character information stored in the storage unit 27 with the current date and time counted by the clock unit 28 in the same manner as “delete”. However, “Delete” focuses on the past date and time relative to the current date and time, while “Select” focuses on the future date and time relative to the current date and time. That is, in “select”, when the date and time extracted by the date and time extraction unit 202 from the storage unit 27 includes a date and time that is in the future with respect to the current date and time, the name of the character information including the date and time (that is, the file Name) and “selection” instructions are notified to the data management unit 204.

  Here, the character information whose name is notified to the data management unit 204 among the character information stored in the storage unit 27 is the date and time when the communication with the common entrance handset 3 ends and the date and time when the character information expires. Selected by relationship. Basically, one piece of character information having the smallest difference between the date and time of the expiration date and the date and time when the communication is completed is selected. However, character information whose expiration date / time is within one week from the communication end date / time or a predetermined number of character information whose expiration date / time is close to the communication end date / time may be selected. When the comparison unit 203 selects a plurality of character information, the data management unit 204 presents a list of character information names on the display device 25, and when the resident selects a desired name, the character information The content may be displayed on the display device 25. Alternatively, the data management unit 204 may present one character information of the plurality of character information on the display device 25 and present other character information on the display device 25 in order.

  The character information extracted from the storage unit 27 may be presented as an image to the voice input / output device 23 through the data conversion unit 201 in addition to being presented as an image on the display device 25 through the data conversion unit 201. If voice presentation is performed, even a resident who is visually impaired can receive text information.

Since allowing the processing of "selection" as described above, when a call with common entrance handset 3 by using the housing information panel 2, along with the call termination, information events that forthcoming the implementation date Is automatically presented on the display device 25. Therefore, a resident who uses the house information board 2 is alerted to an event whose implementation date is approaching without performing a special operation.

  In addition, not only at the time of the end of the call with the common entrance cordless handset 3 but also when the predetermined time before the expiration date of the character information (for example, 5 hours ago, the day before), the character information is presented to the display device 25. You may employ | adopt the structure to do. In this case, the date and time extraction unit 202 can extract in advance the date and time of the expiration date from the character information stored in the storage unit 27, and create a list of the date and time before the predetermined time for the extracted expiration date. That's fine. The comparison unit 203 constantly compares the date and time list with the current date and time counted by the clock unit 28, so that when the current date and time match the date and time included in the list, the corresponding character information is displayed on the display device 25. You may make it show.

Depending on the resident who uses the house information board 2, the “selection” process may be unnecessary. Therefore, the house information board 2 may be set to enable / disable the operation of performing “selection”. When the “select” operation is set to be invalid, the character information stored in the storage unit 27 is presented on the display device 25 by performing an instruction operation on the house information panel 2. In addition, when the “select” operation is set to be effective, when the character information is presented, the character input / output device 23 is used to output the notification sound, turn on an unillustrated indicator light, etc. May be notified.

  The operations of the control unit 20 described above are collectively shown in FIG. In the illustrated example, the case where “update” is performed based on the title is illustrated, but when performed based on the date and time, the “title” is replaced with “date and time”. Note that FIG. 7 does not show a case where “update” is performed under the condition of both the date and the title. In addition, a case where all the operations of “delete”, “update”, and “select” are validated is described.

  When the house information board 2 receives the character information (S11), the date and time extraction unit 202 extracts the date and time corresponding to the expiration date from the received character information (S12). The comparison unit 203 compares the date and time extracted by the date and time extraction unit 202 with the date and time extracted from the character information stored in the storage unit 27 (S13). If it matches the date and time extracted from the storage unit 27 (S13: Yes), the data management unit 204 replaces the character information with the same date and time among the character information stored in the storage unit 27 with the received character information (S14). This operation corresponds to “update”. If the date and time extracted by the date and time extraction unit 202 does not match the date and time extracted from the character information stored in the storage unit 27 (S13: No), the received character information is stored in the storage unit 27 (S15).

  Next, when the time comes (S16: Yes), the date and time extraction unit 202 compares the date and time corresponding to the expiration date of the character information stored in the storage unit 27 with the current date and time counted by the clock unit 28. (S17). When the date and time extracted from the character information stored in the storage unit 27 is a past date and time with respect to the current date and time (S17: Yes), the character information that matches the date and time among the character information stored in the storage unit 27 "Delete" is performed (S18). If the time is not fixed (S16: No) or the date and time extracted from the character information stored in the storage unit 27 is not the past (S17: No), the process proceeds to the next process without performing anything.

  When the communication detection unit 206 detects that the call with the common entrance cordless handset 3 has ended (S19: Yes), the comparison unit 203 extracts from the storage unit 27 character information that is approaching the date and time corresponding to the expiration date. The extracted character information is displayed on the display device 25 (S20). When the communication detection unit 206 does not detect the end of the call (S19: No), the process proceeds to the next process.

  The processing procedure shown in FIG. 7 is an outline of main processing for character information in the house information board 2, and details of each processing are as described above.
