The "fire alarm operation" referred to here is an operation of notifying the occurrence of a fire to the outside of the exclusive unit 23 (for example, the control room master unit 14), an operation of issuing an alarm sound from the speaker 107 of the own unit, and an operation of issuing an alarm sound. It includes an operation of displaying the fact that a fire has occurred on the display unit 105 of the own machine. Further, the "fire alarm operation" includes an operation of issuing an alarm sound from the speaker of the living room slave unit 12 connected to the own unit.

When the outbreak of a fire is detected in another exclusive unit 23 or the common unit 22, the housing information board A1 receives that fact from, for example, the receiver 18, and issues an alarm sound from the speaker 107 of the own unit. The display unit 105 of the own unit displays the fact that a fire has occurred, and the living room slave unit 12 issues an alarm sound. These operations are also included in the "fire alarm operation".

When the control device 8 receives the signal related to the detection signal from the housing information board A1 that has received the detection signal, the control device 8 notifies the server (for example, the server of the security company, which may be the server system 4) of the occurrence of a fire.

In addition, the occurrence of a fire was detected in each living room slave unit 12 by pressing a test button or connecting an external testing machine to a repeater incorporated in the living room slave unit 12 to transmit a test signal. A test of the same operation as in the case can be executed by the housing information board A1 connected to the living room slave unit 12. These operation tests are also included in the "fire alarm operation".

[Intercom function]
Next, the intercom function, which is one of the other functions, will be briefly described. The intercom function is a function related to an intercom call.

The processing unit C12 executes and processes software corresponding to the intercom function, and performs a basic operation as a living room master unit. Specifically, the processing unit C12 executes audio processing, video processing, call processing, and the like. That is, the "function related to intercom call" here includes not only the function of the call (transmission / reception of audio signal) itself but also the function related to video and call.

As described above, the audio processing includes a process of converting (demodulating) a digital audio signal into an analog audio signal and outputting it from the speaker 107, a process of capturing the audio signal picked up by the microphone 108, and the like. The voice processing also includes processing such as noise removal and echo removal for the voice signal.

The video processing is a process of displaying the video information (moving image, still image, etc.) of the visitor taken by the imaging unit of the lobby intercom 13 or the living room slave unit 12 on the display unit 105 or recording it on the storage unit 106. .. The video processing also includes processing such as distortion correction, enlargement / reduction, and trimming of the video information.

The calling process includes a process of ringing a ringing tone from the speaker 107 when a calling operation is executed by the lobby intercom 13, the living room slave unit 12, or the management room master unit 14. The call process also includes a process corresponding to the operation input (for example, a process of starting a call) when the user inputs an operation to the operation unit 104 or the display unit 105 in response to the call.

Further, the housing information board A1 can transfer the call to the terminal T1 of the user of the exclusive unit 23 when the call operation is executed by the lobby intercom 13, the living room slave unit 12, or the management room master unit 14. .. Dedicated application software for realizing communication with the housing information board A1 is pre-installed on the terminal T1. In short, the user of the exclusive unit 23 can make a call with the visitor while watching the image of the visitor (or the manager or the like) displayed on the display unit of the terminal T1 in response to the call using the terminal T1. Such a transfer function is also one of the intercom functions.

[Other features]
Next, other functions (application function, communication function, font function, and crime prevention function) other than the intercom function will be briefly described. The other functions mentioned here are merely examples, and are not limited thereto.

The application function receives living information such as a weather forecast and a weather warning from an external server (may be a server system 4) and notifies the display unit 105 by push notification or the like, or transfers it to the user's terminal T1. Including the function to do. The application function includes a function of notifying the user's terminal T1 when the housing information board A1 executes the above-mentioned "fire alarm operation". Further, the application function includes a function of notifying the display unit 105 of the arrival of the parcel in the delivery box installed in the common unit 22 or the like or transferring the parcel to the user's terminal T1. Further, the application function receives a communication item from the manager or the management company (for example, a communication regarding the inspection date of the fire detector) from the management room master unit 14 or the server system 4 and notifies the display unit 105. It also includes a function of transferring to the user's terminal T1.

The communication function is to encrypt (convert) data according to a predetermined rule so that the first communication unit 101 does not misuse it by a third party on the way when transmitting and receiving data on the network NT1 such as the Internet. Includes decryption function. Further, the communication function includes a function of presenting and confirming a security certificate (server certificate) when communicating with the server system 4 via the network NT1 in the first communication unit 101. The housing information board A1 confirms whether or not the server to be connected (here, for example, the server system 4) is a reliable server through the security certificate. Then, here, the update program in the above-mentioned update information may include a program relating to at least one of the encryption method and the security certificate in the communication function.

The font function is, for example, a function for designating a display form of character string data, symbol data, and the like on the display unit 105 (including the display unit of the terminal T1 as the transfer destination) when the application function or the like is executed. Specifically, the font function is a function for designating a font type (types such as Japanese, English, Chinese, and Korean), a font size, and an arrangement (left edge alignment, center alignment, etc.).

The crime prevention function includes a function of linking with the crime prevention system introduced in the collective facility 2. The security system includes one or more security sensors that are electrically connected to the housing information panel A1, and when the housing information panel A1 receives a signal that detects a suspicious person from the security sensor, it sounds an alarm or manages it. Notify the room master unit 14. If a HEMS (Home Energy Management System) controller that monitors and manages various electrical devices in the exclusive unit 23 is provided separately from the housing information panel A1, the housing information panel A1 is electrically connected to the controller. Then, a signal for detecting a suspicious person may be received from the security sensor via the controller.

In particular, the crime prevention function includes a function of selecting an outing mode, a home mode, or the like according to an operation input to the operation unit 104. For example, when the resident goes out, the housing information board A1 implements crime prevention alert by operating the operation unit 104 to set the outing mode. When the entrance door or window of the exclusive unit 23 is opened or destroyed while going out, the housing information board A1 sounds an alarm sound to notify the management room master unit 14 and at the same time notifies the user terminal T1. .. When the window or door is opened, the housing information board A1 stores the place of occurrence, the time of occurrence, and the like as history information in the storage unit 106. The resident can confirm the history information through the display unit 105. In addition, when the resident switches to the outing mode before going out, the housing information board A1 changes the locked / unlocked state of the entrance door and the window of the exclusive unit 23 at that time after a certain period of time has passed, to the user's terminal T1. Notify to. When the resident returns home and switches to the home mode, the crime prevention alert is released.

By the way, if the update software is attacked by a virus or the like, or if the update software has a problem, the disaster prevention function of the housing information board A1 that executes the fire alarm operation may be hindered. There is a concern that the alarm operation may not be performed normally during software update. Therefore, in the present embodiment, the update information received by the housing information board A1 does not include the update program for updating the software related to the disaster prevention function.

Further, even if an update program for updating software related to the disaster prevention function is included in the received update information, the update unit C11 is configured not to execute the update program. For example, the update unit C11 confirms whether or not the prohibition flag "1" indicating update prohibition is given to the update program in the received update information, and if the prohibition flag "1" is given, the update is performed. Skip program execution and discard data. That is, the update unit C11 is configured so that the specifications related to the operation of the disaster prevention function (specific function) are not changed.

On the other hand, for functions other than the disaster prevention function, considering the convenience of the user (resident), if you want to change the service provision form to the user to the latest state without the need to replace the housing information board A1. There is. Further, depending on the communication system configuration of the collective facility 2 to which the intercom system 1 is applied, the required security certificate and encryption method, and the functional specifications required by the user are also diverse. At the stage when the housing information board A1 is manufactured and shipped, it is not possible to incorporate software and setting data into the housing information board A1 so that all security certificates, encryption methods, and functional specifications can be covered. , The storage capacity of the control unit C1 may be larger than necessary.

Therefore, as described above, the housing information board A1 can be updated for functions other than the disaster prevention function. That is, the update unit C11 executes the update program for the update program to which the prohibition flag "1" indicating the update prohibition is not given in the received update information. In this case, the prohibition flag "1" is not given to the update program for updating the software related to other functions. However, the housing information board A1 needs to give the highest priority to the execution related to the operation of the fire alarm. Therefore, in the housing information board A1, the execution of the update program for updating the software related to other functions is performed so as not to interfere with the execution of the operation of the fire alarm. That is, the update unit C11 is configured so that the operation is not changed while the disaster prevention function (specific function) is being executed. As a result, the operation of the fire alarm overlaps with the update of software related to other functions, the disaster prevention is temporarily unmonitored, the issuance of the fire alarm is delayed, or the worst. In some cases, situations such as false alarms can be suppressed.

However, for example, when manufacturing a new product housing information board A1, there is a case where it is desired to update the disaster prevention function of the old product housing information board A1. Therefore, the connection portion 11 of the housing information board A1 is configured to be electrically connected to the rewriting device W1. The connection unit 11 is, for example, a connection port to which the connection connector of the rewriting device W1 is connected. The software related to the disaster prevention function (specific function) is updated via the rewriting device W1 connected to the connection unit 11. The rewriting device W1 assumes, for example, a ROM writer. It is desirable that the connection portion 11 is not exposed from the housing of the housing information board A1 so that the disaster prevention function is not updated by being misused by a third party.

(2.4) Gateway device Next, the configuration of the gateway device 7 will be described in detail with reference to FIGS. 1 and 2B.

The gateway device 7 is configured to make a communication connection between the server system 4 and the information terminal 10 introduced in each facility 5 in the collective facility 2 via the control device 8 that controls the communication of the information terminal 10.

As shown in FIG. 2B, the gateway device 7 includes a first communication unit 71, a second communication unit 72, a control unit C2, and a storage unit 74.

The first communication unit 71 is a communication interface for communicating with the housing information board A1 (information terminal 10) having a plurality of functions including a disaster prevention function (specific function) and other functions. The first communication unit 71 is electrically connected to the control device 8 by, for example, a LAN cable. The communication method with the control device 8 is not limited to wired, and may be wireless. The first communication unit 71 is configured to be capable of bidirectional communication with each of the housing information board A1, the management room master unit 14, and the lobby intercom 13 of each exclusive unit 23 via the control device 8 and the trunk line L1. .. That is, the first communication unit 71 communicates with the information terminal 10 via the control device 8.

The second communication unit 72 is a communication interface for communicating with the server system 4. The second communication unit 72 is electrically connected to the HUB device 15 by, for example, a LAN cable. The communication method with the HUB device 15 is not limited to wired, and may be wireless. The second communication unit 72 is configured to be able to communicate with the server system 4 in both directions via the HUB device 15, the router B1, and the network NT1. The second communication unit 72 communicates with the server system 4 and receives update information including an update program for updating the software of the information terminal 10 from the server system 4. In particular, the second communication unit 72 receives from the server system 4 update information including an update program for updating software related to at least the other function among the plurality of functions.

The storage unit 74 is a memory in which data can be rewritten, and is preferably a non-volatile memory. The storage unit 74 stores identification information (address, etc.) for identifying the communication destination. Further, the storage unit 74 stores various information received from each of the housing information board A1, the management room master unit 14, and the lobby intercom 13 of each exclusive unit 23. Further, the storage unit 74 stores various information (update information and the like) received from the server system 4.

The control unit C2 mainly comprises a computer system having one or more processors and one or more memories. In the control unit C2, the functions of each unit of the control unit C2 are realized by executing a program recorded in the memory by one or more processors. The program may be pre-recorded in a memory, provided through a telecommunication line such as the Internet, or may be recorded and provided on a non-temporary recording medium such as a memory card.

The control unit C2 controls the first communication unit 71, the second communication unit 72, the storage unit 74, and the like. Further, the control unit C2 has a processing unit 73 and a management unit 75. That is, the control unit C1 has a function as a processing unit 73 and a function as a management unit 75.

The processing unit 73 stores the update program received from the server system 4 in the storage unit 74. Then, the processing unit 73 of the present embodiment is configured to deliver the update program stored in the storage unit 74 from the first communication unit 71 to the housing information board A1 (information terminal 10).

The distribution target of the update program may be the housing information board A1 of all the exclusive units 23, or may be only a part of the housing information board A1. In particular, the update program may be simultaneously distributed to the housing information boards A1 of all the exclusive units 23 without considering the situation in each housing information board A1, but here, each housing information board A1 It shall be delivered in consideration of the situation. The "situation in each housing information board A1" referred to here may include at least one of a setting status, an operating status, and a power supply status related to each function. That is, as an example, when the distribution target of the update program is a plurality of information terminals 10 in a plurality of exclusive units 23 (facility 5), the processing unit 73 is individually addressed to the plurality of information terminals 10 by the first communication unit 71. Deliver updates to. As shown below, "individual distribution" here means selecting whether or not to send an update program for each housing information board A1 and shifting the distribution timing instead of "simultaneously". including.

[Setting status]
First, a case where the processing unit 73 considers the setting status related to each function will be described. The housing information board A1 may be set to an unusable state for some of the "other functions" according to the user's request or the installation environment of the housing information board A1. For example, when the application function of another function is a function using an electric device in the exclusive section 23, the electric device is not installed in the exclusive section 23 of the user, or the user uses the electric device. Without it, such a feature could be unnecessary. Then, it may not be necessary to update the software related to the function.

Therefore, the processing unit 73 acquires setting information indicating whether or not each function in the other function does not need to be updated from the housing information board A1 of each exclusive unit 23, and stores it in the storage unit 74. The processing unit 73 determines which housing information board A1 is the target of distribution of the update program received from the server system 4 based on the setting information stored in the storage unit 74.

[Operating conditions]
Next, a case where the processing unit 73 considers the operating status of each housing information board A1 will be described. The operation status of the housing information board A1 is different in each exclusive section 23. For example, if the housing information board A of a certain exclusive unit 23 receives a ringing signal from the lobby intercom 13 and is ringing, or if the user is talking to a visitor on the lobby intercom 13 side, the housing information board A1 is used. , The intercom function is activated. Hereinafter, this state is referred to as "using the intercom function". If the reception of the update program or the software update is started while the intercom function is being used, it may interfere with the ringing tone, the call with the visitor, the confirmation of the visitor's image, and the like. In particular, if the software to be updated is related to the intercom function, the currently running intercom function may become abnormal. Of course, even if a function other than the intercom function is being executed, reception of an update program and software update may hinder the execution as well.

Therefore, the processing unit 73 is configured to determine the status of the information terminal 10 from the operation information and control the distribution of the update program based on the status. Specifically, when the housing information board A1 (information terminal 10) becomes "in use of the intercom function", the housing information board A1 (information terminal 10) transmits operation information indicating that fact to the gateway device 7. As a result, the gateway device 7 can always grasp the usage status of the intercom function of each housing information board A1. Of course, each housing information board A1 may transmit operation information even when a function other than the intercom function is in use.

Further, the processing unit 73 may transmit a request signal for confirming the current operating status of the distribution target of the update program from the first communication unit 71 to the distribution target at the timing of receiving the update information. Upon receiving the request signal from the gateway device 7, the housing information board A1 may transmit an operation status signal including operation information regarding the current operation from the second communication unit 102 to the gateway device 7.

Then, the processing unit 73 determines whether or not to distribute the update program at the current timing for the distribution target based on the received operation information. When the processing unit 73 determines that, among other functions, a function that should be prioritized over the distribution of the update program is currently non-executed, the processing unit 73 starts distribution to the distribution target. On the other hand, when the processing unit 73 determines that the distribution target is currently executing a function that should be prioritized over the distribution of the update program among other functions, the distribution target is sent to the distribution target until the execution of the function is completed. Put the delivery on hold. That is, the first communication unit 71 acquires the operation information related to the operation of the information terminal 10, and the processing unit 73 distributes the update program from the first communication unit 71 to the information terminal 10 based on the operation information.

Further, for example, while the gateway device 7 is transmitting an update program to a certain distribution target housing information board A1, the housing information board A1 may start executing an intercom function such as ringing tone or calling (a call). Occurrence of interrupt). While receiving the update program, the housing information board A1 transmits an operation status signal including operation information indicating that execution of another function has started to the gateway device 7. In this case, the processing unit 73 temporarily suspends (may be canceled) the distribution of the update program to the distribution target, and suspends the distribution to the distribution target until the execution of the function is completed.

As described above, in the present embodiment, when the processing unit 73 determines from the operation information that the information terminal 10 is executing the operation based on the specific operation, the processing unit 73 cancels or interrupts the distribution of the update program to the information terminal 10. do. The "specific operation" referred to here is an operation on the lobby intercom 13 (for example, an operation related to a call) and an operation on the management room master unit 14 (for example, an operation related to a call) in addition to an operation on the housing information board A1 (for example, an operation related to a call). For example, operations related to calling) and the like are included.

[Power status]
Next, a case where the processing unit 73 considers the power supply state (power supply status) of each housing information panel A1 will be described. Due to the restrictions of the Fire Service Act, the housing information board A1 is basically assumed to be always on (on state). That is, for example, when a user (resident) goes out for a long period of time, the branch breaker of the distribution board installed in the exclusive unit 23 may be turned off. In this case, the power of the router B2, the HUB device 16, and the like in the exclusive unit 23 may be turned off. As a result, there is a possibility that the second communication path RT2 cannot be used as the path for receiving the update information.

On the other hand, the housing information board A1 is configured to receive power supply through a dedicated branch breaker in the distribution board. As a result, the possibility that the user accidentally stops the power supply of the housing information board A1 when going out is suppressed as in the case of the router B2 and the HUB device 16. However, there may be a housing information board A1 whose power is off for some reason. For example, while the housing information board A1 has already been installed in the private section 23, if a new resident has not yet moved into the private section 23, the power of the housing information board A1 may be off. .. In this case, even if the update program is distributed, it may not be received by the housing information board A1.

Further, in the collective facility 2, the power supply of the equipment installed in the common unit 22 and the MDF room 24 such as the gateway device 7 is a power system different from the power supply of the electric equipment in each exclusive unit 23. There is. In particular, the common area 22 and the MDF room 24 are provided with an emergency power supply so that they can be backed up even if a power failure occurs. Therefore, the gateway device 7 and the like can operate by receiving power supply from the emergency power supply even if a power failure or the like occurs.

In short, the distribution of the update program from the second communication path RT2 may not be normally performed depending on the power supply state of the electrical equipment (including the housing information board A1) in the exclusive unit 23. However, the distribution of the update program from the trunk line L1 via the first communication path RT1 is not easily affected by the power supply state. In other words, it is more likely that the distribution of the update program from the trunk line L1 via the first communication path RT1 can update the software more efficiently than the distribution from the second communication path RT2.

Therefore, the first communication unit 71 acquires the power supply information regarding the power supply state of the housing information board A1 (information terminal 10). Based on the power supply information (hereinafter referred to as "first power supply information"), the processing unit 73 suspends or interrupts the distribution of the update program to the housing information board A1 in which the power supply is off, and the power supply is turned on. The update program is distributed to the housing information board A1 which is in the state. That is, the gateway device 7 monitors the power supply state of each housing information board A1 (information terminal 10). The first power supply information is transmitted from each housing information board A1 via the trunk line L1 and the control device 8. For example, the gateway device 7 may transmit a confirmation signal to the housing information board A1, and if there is no response, it may be considered that the gateway device 7 has received the first power supply information that the power supply is in the off state.

Further, the gateway device 7 monitors the power supply status to each housing information board A1, suspends or interrupts the distribution of the update program to the housing information board A1 in which the power is not supplied, and the power is supplied. The update program may be distributed to the housing information board A1.

The source of the first power supply information is not limited to the housing information board A1, and when the HEMS controller is installed in the exclusive unit 23, it is the HEMS controller that monitors the power consumption in the housing information board A1. May be good.

By distributing the update program to the housing information board A1 in which the power is on in this way, the reliability of the communication of the update program can be further improved.

In addition to the power information of the housing information board A1 (information terminal 10), the first communication unit 71 also has power information related to the power status of the router B2 and the HUB device 16 in the exclusive unit 23 (hereinafter, "second power information"). ") Is also acquired. The second power supply information is transmitted from the housing information board A1 that monitors the router B2, the HUB device 16, and the like. The processing unit 73 determines whether or not at least one of the router B2 and the HUB device 16 is in the off state based on the second power supply information. When the processing unit 73 determines that at least one of the above power sources is in the off state, the second communication path RT2 may not be available for the exclusive unit 23, so the first communication path RT1 is used. The gateway device 7 distributes the update program.

In other words, the processing unit 73 determines for each housing information board A1 which of the first communication path RT1 and the second communication path RT2 should be used to cause the housing information board A1 to receive the update program. You may. As described above, the determination criterion may be based on the power supply state or other information (for example, the communication status of the trunk line L1). The gateway device 7 transmits an instruction signal to the housing information board A1 via the control device 8 and the trunk line L1 based on the determination result. The transmission of the instruction signal may be omitted from the housing information board A1 in which the gateway device 7 distributes the update program using the first communication path RT1, and the distribution may be started as it is. On the other hand, when it is determined that the housing information board A1 should directly receive the update program using the second communication path RT2, it is desirable to transmit an instruction signal to the housing information board A1. Further, this determination function may be provided in the server system 4 instead of the gateway device 7. In this case, the server system 4 collects the first power supply information and the second power supply information from each exclusive unit 23 through the first communication path RT1 or the second communication path RT2.

By the way, if the update program received from the server system 4 includes an update program for updating software related to the disaster prevention function, the processing unit 73 discards the update program and updates other than that. Determine the distribution target for the program. The processing unit 73 may determine whether or not the update program is for the disaster prevention function from the module name (file name) of the update program or its code information, and the prohibition flag "1" has already been added. If so, it may be determined based on the prohibition flag. The prohibition flag "1" may be added by the gateway device 7. When the prohibition flag "1" is already assigned on the intercom system 1 side, or when the gateway device 7 assigns the prohibition flag "1", the update program for the disaster prevention function is combined with the update program for other functions. It may be distributed and destroyed on the side of the housing information board A1.

In short, the assignment of the prohibition flag "1" is not essential in the intercom system 1 of the present disclosure, and the assignment may be performed by the server system 4 or the gateway device 7. Further, the update program for the disaster prevention function may be discarded by the gateway device 7 or the housing information board A1. As a matter of course, the server system 4 may transmit the update information in a form that does not include the update program for the disaster prevention function.

In this way, the gateway device 7 transmits the update information received by the second communication unit 72 from the first communication unit 71 to the information terminal 10, so that the operation of the specific function is not changed based on the update information. To run the update.

By the way, the management unit 75 of the control unit C2 is configured to manage the distribution of the update program to the information terminal 10. Specifically, the management unit 75 is configured to receive a reception completion signal indicating that the reception of the update program has been completed from each housing information board A1 to be distributed. Conversely, each housing information board A1 is configured to notify the gateway device 7 on the distribution side of a reception completion signal indicating how much file data has been received for a plurality of file data related to the update program. .. The reception completion signal is transmitted, for example, each time the reception of each file data is completed. When the management unit 75 determines that the reception of all the file data is completed based on the reception completion signal, the management unit 75 sets a distribution completion flag for the housing information board A1 which is the transmission source of the reception completion signal. After confirming that the distribution completion flag is set in all the housing information boards A1 to be distributed, the processing unit 73 discards (deletes) the update program data stored in the storage unit 74. In other words, the processing unit 73 stores the update program in the storage unit 74 until the distribution of the update program is completed to all the information terminals 10 to which the update program is distributed among the plurality of information terminals 10 in the plurality of facilities 5. The storage unit 74 maintains the updated program.

The "completion of distribution" referred to here is not limited to the completion of reception of all file data on all the housing information boards A to be distributed as described above. In other words, the configuration for receiving the reception completion signal from each housing information board A is not essential. For example, when the processing unit 73 unilaterally completes the transmission to all the housing information boards A1 to be distributed, the processing unit 73 determines that the distribution is completed, and the data of a series of update programs stored in the storage unit 74. May be discarded.

(2.5) Server System Next, the configuration of the server system 4 will be described in detail with reference to FIGS. 1 and 2C.

The server system 4 collectively manages updates for transmission to at least one or a plurality of collective facilities 2 (only one is shown in FIG. 1). The server system 4 manages various software programs in addition to the update program. As shown in FIG. 2C, the server system 4 includes a server-side communication unit 41, a control unit C3, and a storage unit 43.

The server-side communication unit 41 is a communication interface for communicating with the equipment on the side of the collective facility 2. The server-side communication unit 41 is configured to communicate with the information terminal 10. Further, the server-side communication unit 41 is configured to communicate with the gateway device 7.

Specifically, the server-side communication unit 41 communicates with the gateway device 7 via the network NT1, the router B1, and the HUB device 15. Further, the server-side communication unit 41 communicates with the information terminal 10 via the network NT1, the router B2, and the HUB device 16.

The storage unit 43 is a memory in which data can be rewritten, and is preferably a non-volatile memory. The storage unit 43 stores identification information (address, etc.) for identifying the communication destination. Further, the storage unit 43 stores various information received from each of the housing information board A1, the management room master unit 14, and the lobby intercom 13 of each exclusive unit 23. Further, the storage unit 43 stores various information (update information and the like) received from the gateway device 7. In particular, the storage unit 43 stores the update program for distribution to the collective facility 2, for example, in module units (see FIG. 1).

The control unit C3 mainly comprises a computer system having one or more processors and one or more memories. In the control unit C3, the functions of each unit of the control unit C3 are realized by executing a program recorded in the memory by one or more processors. The program may be pre-recorded in a memory, provided through a telecommunication line such as the Internet, or may be recorded and provided on a non-temporary recording medium such as a memory card.

The control unit C3 controls the server-side communication unit 41, the storage unit 43, and the like. Further, the control unit C3 has a generation unit 42 (see FIG. 2C). That is, the control unit C1 has a function as a generation unit 42.

The generation unit 42 is configured to generate update information including an update program, and the server system 4 transmits the update information generated by the generation unit 42 from the server-side communication unit 41 to the gateway device 7 for distribution. The target information terminal 10 is made to execute the update program. That is, in this case, the update information is transmitted to the collective facility 2 side using the first communication path RT1.

In particular, in the present embodiment, the generation unit 42 generates update information including an update program for updating software related to at least "another function" among a plurality of functions. Then, the server system 4 transmits the update information generated by the generation unit 42 from the server-side communication unit 41 to the information terminal 10, and the operation of the disaster prevention function (specific function) is changed based on the update information. Run the update so that it doesn't. That is, in this case, the update information is transmitted to the collective facility 2 side using the second communication path RT2.

Here, the generation unit 42 acquires the update program from the outside of the system and generates the update information using the acquired update program, but the update program itself may be generated.

Here, the server system 4 of the present embodiment manages the update program in module units as described above. Specifically, the server system 4 manages a plurality of functions of the housing information board A1 (information terminal 10) by storing a plurality of modules M1 (see FIG. 1) divided into functional units in a storage unit 43. do. The "module" here is a file that contains updates. The plurality of modules M1 include, for example, a (security) certificate module, an encryption module, an application module, a font module, a disaster prevention module, and a call module.

The certificate module contains the latest version updates for software related to security certificates in communication functions. The encryption module contains the latest version of the update for the software related to the encryption method in the communication function. The app module contains the latest version updates for software related to application features. The font module contains the latest version updates for software related to font functionality. The disaster prevention module contains the latest version updates for software related to disaster prevention features. The calling module contains updates for software related to intercom functionality. In addition, each module M1 may include not only the latest version update program but also all execution programs of software related to the corresponding function, an old version update program, and the like.

The server system 4 includes the above-mentioned unit of the plurality of modules M1, that is, one or a plurality of modules M1 in the update information, and transmits the plurality of modules M1 through the first communication path RT1 or the second communication path RT2 in response to the specific trigger. Here, as an example, it is assumed that the "specific trigger" means that the version of the update program in a certain module M1 has been upgraded.

The server system 4 includes only the upgraded module M1 of the update program in the update information and transmits it. Here, as an example, the server system 4 excludes the update program for the disaster prevention function from the transmission target. As a result, it is not necessary to select only the update program for the disaster prevention function on the side of the housing information board A1 or the gateway device 7.

However, the server system 4 may give the prohibition flag "1" to the update program for the disaster prevention function and transmit the update information including all the plurality of modules M1. In this case, the update program to which the prohibition flag "1" is given on the side of the housing information board A1 or the gateway device 7 is discarded without being executed or distributed.

The server system 4 may, for example, periodically include one or a plurality of modules M1 in the update information and automatically transmit the one or a plurality of modules M1 to the side of the one or a plurality of collective facilities 2. That is, the "specific trigger" may be the arrival of a specific date and time (for example, midnight every day, midnight on the last day of the month, etc.).

Alternatively, the "specific trigger" may be to receive an update information request signal requesting transmission of an update program from the side of the collective facility 2 (house information board A1 or gateway device 7). The update information request signal may be automatically transmitted from the side of the collective facility 2 on a regular basis, or may be transmitted in response to a manual operation by a user (resident or manager of the management room 21).

(2.6) Explanation of Operation Hereinafter, regarding the operation of the intercom system 1, distribution of an update program using the first communication path RT1 (operation example 1 and operation example 2) and an update program using the second communication path RT2 (Operation example 3 and operation example 4) will be described separately. However, the series of operation procedures described below is merely an example and is not particularly limited. Further, as an example below, it is assumed that the collective facility 2 has rooms 101 to 500 as a plurality of exclusive units 23. The housing information board A1 in room 101 is called "first housing information board A11", the housing information board A1 in room 102 is called "second housing information board A12", and the last housing information board A1 in room 500 is called. It is called "third housing information board A13" (see FIGS. 3 to 5).

Further, here, the gateway device 7 will be described with the case where the operating status (usage status of the intercom function) is taken into consideration among the setting status, the operating status, and the power supply status as the “status in the housing information panel A1”.

[Operation example 1]
First, the distribution of the update program using the first communication path RT1 will be described with reference to FIG.

The server system 4 excludes the update program for the disaster prevention function, generates update information including the upgraded update program for each module (step S1), and transmits the update information to the gateway device 7 (step S2).

When the gateway device 7 receives the update information via the first communication path RT1, it stores the update information once in the storage unit 74, and performs the update program distribution process, for example, targeting all the dwelling units (rooms 101 to 500) as distribution targets. Start (step S3). However, it is said that the second housing information board A12 in Room 102 started processing a call with, for example, the lobby intercom 13 at a time before the time t1 when the update information was received, and switched to "using the intercom function". do. At time t0, the second housing information board A12 transmits operation information indicating that “the intercom function is in use” to the gateway device 7 (step S4). The gateway device 7 receives operation information from the second housing information board A12 via the control device 8, and as a result, it is determined that the second housing information board A12 is "using the intercom function".

First, the gateway device 7 transmits an update program to the first housing information board A11 in room 101 via the control device 8 and the trunk line L1 in the distribution process (step S5).

Next, since the gateway device 7 is "in use of the intercom function" in the second housing information board A12 in room 102, the transmission of the update program to the second housing information board A12 is skipped, and the houses in rooms 103 and after are skipped. Transmission to the information board A1 is performed in sequence. On the other hand, when each housing information board A1 completes the reception (download) of the update program, the reception completion signal is transmitted to the gateway device 7, and the update program is executed to update the software related to the corresponding function. It is desirable that each housing information board A1 notifies the user (resident) from the display unit 105 or the terminal T1 that the software has been updated.

Then, when the transmission to the third housing information board A13 (step S6) of the last room No. 500 is completed, the gateway device 7 skips the transmission of one or more housing information boards A1 (here, the second housing information board A12). Only), check the operating status before sending the update program. Here, the gateway device 7 waits until "in use of the intercom function" is canceled on the second housing information board A12.

When the second housing information board A12 finishes the call processing with the lobby intercom 13, the second housing information board A12 transmits the operation information indicating that "the intercom function is in use" has been canceled to the gateway device 7 at time t2 (step S7). .. When the gateway device 7 receives the above operation information, it transmits an update program to the second housing information board A12 (step S8).

When the gateway device 7 confirms the distribution completion flag and determines that the reception completion signal has been received from all the housing information boards A1, the gateway device 7 ends the distribution process of the update program (step S9). Further, the gateway device 7 deletes the delivered update program from the storage unit 74. That is, the gateway device 7 causes the storage unit 74 to maintain the update program stored in the storage unit 74 until the distribution of the update program is completed for all the housing information boards A1 to which the update program is distributed. Therefore, it is possible to reduce the possibility that the housing information board A1 in which software update is omitted occurs.

It is desirable that the gateway device 7 notifies the server system 4 that the distribution of the update program is completed.

[Operation example 2]
Next, in the distribution of the update program using the first communication path RT1, when the call processing is started on the housing information board A1 while the update program is being transmitted to a certain housing information board A1 ( The occurrence of an interrupt) will be described with reference to FIG. In FIG. 4, it is assumed that an interrupt occurs in the first housing information board A11 in Room 101. Further, the parts common to the above [Operation Example 1] will be briefly described by omitting them as appropriate.

The server system 4 generates update information (step S11) and transmits it to the gateway device 7 (step S12).

When the gateway device 7 receives the update information via the first communication path RT1, the gateway device 7 starts the distribution process of the update program (step S13). The gateway device 7 transmits an update program to the first housing information board A11 in room 101 in the distribution process (step S14).

Here, it is assumed that while the update program is being transmitted to the first housing information board A11 (the update program is being downloaded), a call process occurs on the first housing information board A11 at time t11, and the system is switched to "using the intercom function". .. The first housing information board A11 transmits operation information indicating that “the intercom function is in use” to the gateway device 7 (step S15). When the gateway device 7 receives the operation information, the gateway device 7 temporarily suspends the transmission of the update program to the first housing information board A11 (step S16). For example, when the gateway device 7 completes the transmission of the 1st to 10th file data out of the 20 file data related to the update program and the call processing occurs during the transmission of the 11th file data, the 11th and subsequent file data are transmitted. Suspends the transmission of file data.

Since the gateway device 7 is "using the intercom function" in the first housing information board A11 in room 101, it is first transmitted to the second housing information board A12 in room 102 (step S17) and the housing information thereafter. Transmission to the board A1 is performed in sequence. Then, when the transmission to the third housing information board A13 of the last room No. 500 (step S18) is completed, the gateway device 7 updates the update program after confirming the operation status of the first housing information board A11 whose transmission is interrupted. Send. When the first housing information board A11 finishes the call processing with the lobby intercom 13, the first housing information board A11 transmits the operation information indicating that "the intercom function is in use" has been canceled to the gateway device 7 at time t12 (step S19). .. Upon receiving the above operation information, the gateway device 7 resumes transmission of the update program to the first housing information board A11 (step S20). That is, the transmission of the eleventh and subsequent file data is started.

Then, the gateway device 7 confirms the distribution completion flag, determines that the reception completion signal has been received from all the housing information boards A1, and ends the distribution process of the update program (step S21).

As described in the operation examples 1 and 2, the gateway device 7 (processing unit 73) acquires the operation information regarding the operation of the housing information board A1 and distributes the update program based on the operation information. Therefore, it is possible to reduce the possibility that the distribution of the update program interferes with the operation of the housing information board A1. In particular, the gateway device 7 determines the status of the housing information board A1 from the operation information, and controls the distribution of the update program based on the status. Therefore, the possibility that the distribution of the update program interferes with the operation of the housing information board A1 can be further reduced.

Further, when the gateway device 7 (processing unit 73) determines from the operation information that the housing information board A1 is executing the operation based on a specific operation, the distribution of the update program to the housing information board A1 is stopped or interrupted. do. Therefore, while giving priority to the operation of the housing information board A1, the reliability of the communication of the update program can be further improved.

[Operation example 3]
Next, the distribution of the update program using the second communication path RT2 will be described with reference to FIG.

The server system 4 excludes the update program for the disaster prevention function, and then generates update information including the upgraded update program for each module (step S31). Then, the server system 4 simultaneously transmits, for example, a notification signal notifying that the update program has been upgraded to all the housing information boards A1 in rooms 101 to 500 in the collective facility 2 (step S32). ).

When each housing information board A1 receives the notification signal, it sends an update information request signal requesting the server system 4 to send the update information at a convenient timing of its own machine, and downloads the update program. Start. That is, when each housing information board A1 receives the notification signal, if it is "in use of the intercom function", it waits without starting the download until "in use of the intercom function" is canceled. ..

Specifically, since the housing information board A1 excluding the second housing information board A12 is not using the intercom function when the notification signal is received, the update information request signal is immediately transmitted (step S33) to update. The download of the program is started (step S34).

On the other hand, it is assumed that the second housing information board A12 starts processing a call with the lobby intercom 13 at a time t30 before the time t31 when the notification signal is received, and switches to "using the intercom function". As a result, the second housing information board A12 waits until "in use of the intercom function" is released, transmits an update information request signal at the released time t32 (step S35), and downloads the update program. Start (step S36).

When each housing information board A1 completes the reception (download) of the update program, the reception completion signal is transmitted to the server system 4, and the update program is executed to update the software related to the corresponding function. It is desirable that each housing information board A1 notifies the user (resident) from the display unit 105 or the terminal T1 that the software has been updated.

[Operation example 4]
Next, regarding the distribution of the update program using the second communication path RT2, when the call processing is started on the housing information board A1 while the update program is being transmitted to a certain housing information board A1 ( Occurrence of an interrupt) will be described with reference to FIG. In FIG. 6, it is assumed that an interrupt occurs in the first housing information board A11 in Room 101. Further, the parts common to the above [Operation Example 3] will be briefly described as appropriate.

The server system 4 excludes the update program for the disaster prevention function, and then generates update information including the upgraded update program for each module (step S41). Then, the server system 4 simultaneously transmits, for example, a notification signal notifying that the update program has been upgraded to all the housing information boards A1 in rooms 101 to 500 in the collective facility 2 (step S42). ).

When each housing information board A1 receives the notification signal, it transmits an update information request signal requesting the server system 4 to transmit the update information at a convenient timing of its own machine, and starts downloading.

Here, since all the housing information boards A1 are not using the intercom function at the time of receiving the notification signal, they immediately transmit the update information request signal (step S43) and start downloading the update program (step S44). ).

However, it is assumed that the first housing information board A11 is switched to "using the intercom function" due to a call processing with the lobby intercom 13 at time t41 while downloading the update program. The first housing information board A11 transmits operation information indicating that "the intercom function is in use" to the server system 4 (step S45). When the server system 4 receives the operation information, the server system 4 temporarily suspends the transmission of the update program to the first housing information board A11 (step S46). If the server system 4 completes the transmission of the 1st to 10th file data out of the 20 file data related to the update program and the call processing occurs during the transmission of the 11th file data, the 11th and subsequent file data are transmitted. Suspend file data transmission.

The first housing information board A11 transmits to the server system 4 operation information indicating that "in use of the intercom function" has been canceled when the call processing with the lobby intercom 13 is completed at time t42 (step S47). Upon receiving the above operation information, the server system 4 resumes transmission of the update program to the first housing information board A11 (step S48). That is, the transmission of the eleventh and subsequent file data is started.

In the operation examples 1 and 2, the gateway device 7 is the main body that controls the distribution of the update program. In the operation examples 3 and 4, the server system 4 controls the distribution of the update program instead of the gateway device 7, so that the load of the distribution control in the gateway device 7 can be reduced.

[advantage]
As described above, in the present embodiment, the update unit C11 of the information terminal 10 executes the update program to update the software based on the update information so that the operation of the disaster prevention function is not changed. Therefore, the disaster prevention function is less likely to interfere with its operation during execution. As a result, improvements can be made regarding function updates. Further, since the intercom system 1 includes such an information terminal 10, it is possible to provide the intercom system 1 capable of improving the function update.

Further, since the first communication unit 101 and the second communication unit 102 of the information terminal 10 receive the update program in the form divided into predetermined units, the software is updated so that the operation of the specific function is not further changed. It will be easier. In particular, since a predetermined unit is a functional unit corresponding to a plurality of functions, it is less likely to interfere with the operation of a function other than the function while updating software related to a certain function, and the function update is further improved. NS.

Other functions include a communication function in addition to the intercom function, and since the update program includes a program related to at least one of the encryption method and the security certificate in the communication function, it becomes easy to update the function related to the communication function. As a result, it becomes easy to improve the reliability of communication.

Further, since the information terminal 10 further includes a connecting portion 11 that is electrically connected to the rewriting device W1, it is possible to provide a means for updating the disaster prevention function.

Further, in the present embodiment, the server system 4 transmits the update information generated by the generation unit 42 from the server-side communication unit 41 to the information terminal 10, and the operation of the specific function is changed based on the update information. Run the update so that it doesn't. Therefore, it is possible to provide a server system 4 capable of improving the function update.

Further, in the present embodiment, the gateway device 7 transmits the update information received by the second communication unit 72 from the first communication unit 71 to the information terminal 10, and the operation of the specific function is changed based on the update information. Run the update so that it doesn't happen. Therefore, it is possible to provide the gateway device 7 capable of improving the function update.

By the way, in the present embodiment, the second communication unit 102 of the information terminal 10 is configured to receive the update information via the trunk line L1 related to the sharing of the collective facility 2. Therefore, it is relatively unlikely that various information will be transmitted and received appropriately depending on the situation of each facility 5 (dwelling unit). For example, the possibility is lower than when the second communication path RT2 is used. As a result, it is possible to improve the reliability of the communication of the update program. Further, since the intercom system 1 includes such a gateway device 7, it is possible to provide the intercom system 1 capable of improving the reliability of the communication of the update program. Further, in the present embodiment, the control device 8 receives the update program distributed from the gateway device 7 to the information terminal 10 and transmits the update program to the information terminal 10 to be distributed. Can be improved.

Further, in the present embodiment, the processing unit 73 of the gateway device 7 distributes the update program stored in the storage unit 74 from the first communication unit 71 to the information terminal 10 via the control device 8. Therefore, it is possible to improve the reliability of the communication of the update program.

Further, when the distribution target of the update program is a plurality of information terminals 10, the processing unit 73 individually distributes the update program to the plurality of information terminals 10. Therefore, for example, the reliability of the communication of the update program can be further improved as compared with the case where the update program is simultaneously distributed to the plurality of information terminals 10 without distinction. In particular, since the processing unit 73 distributes the update program based on the operation information related to the operation of the information terminal 10, it is possible to reduce the possibility that the distribution of the update program interferes with the operation of the information terminal 10.

(3) Modified Example The above embodiment is only one of various embodiments of the present disclosure. The above-described embodiment can be changed in various ways depending on the design and the like as long as the object of the present disclosure can be achieved. Further, the same functions as the information terminal 10, the server system 4, and the gateway device 7 according to the above embodiment are embodied in these processing methods, computer programs, non-temporary recording media on which computer programs are recorded, and the like. May be good.

Specifically, the processing method according to one aspect was introduced into the collective facility 2 and had a plurality of functions including a disaster prevention function (specific function) and at least other functions including an intercom function excluding the disaster prevention function. This is a processing method for updating software in the information terminal 10. The processing method includes a first step and a second step. In the first step, update information including an update program for updating software related to at least another function among a plurality of functions is created or acquired. In the second step, based on the update information, the update program is executed so that the operation of the disaster prevention function is not changed.

Hereinafter, modifications of the above embodiment will be listed. The modifications described below can be applied in combination as appropriate. Hereinafter, the above embodiment may be referred to as a “basic example”.

The information terminal 10, the server system 4, and the gateway device 7 in the present disclosure include a computer system. The main configuration of a computer system is a processor and memory as hardware. When the processor executes the program recorded in the memory of the computer system, the functions as the information terminal 10, the server system 4, and the gateway device 7 in the present disclosure are realized. The program may be pre-recorded in the memory of the computer system, may be provided through a telecommunications line, and may be recorded on a non-temporary recording medium such as a memory card, optical disk, hard disk drive, etc. that can be read by the computer system. May be provided. A processor in a computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large scale integrated circuit (LSI). The integrated circuit such as IC or LSI referred to here has a different name depending on the degree of integration, and includes an integrated circuit called a system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Further, an FPGA (Field-Programmable Gate Array) programmed after the LSI is manufactured, or a logical device capable of reconfiguring the junction relationship inside the LSI or reconfiguring the circuit partition inside the LSI should also be adopted as a processor. Can be done. A plurality of electronic circuits may be integrated on one chip, or may be distributed on a plurality of chips. The plurality of chips may be integrated in one device, or may be distributed in a plurality of devices. The computer system referred to here includes a microprocessor having one or more processors and one or more memories. Therefore, the microprocessor is also composed of one or a plurality of electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

Further, it is not an essential configuration that a plurality of functions in each of the information terminal 10, the server system 4, and the gateway device 7 are integrated in one housing. Each component of the information terminal 10, the server system 4, and the gateway device 7 may be distributed and provided in a plurality of housings. On the contrary, a plurality of functions in each of the information terminal 10, the server system 4, and the gateway device 7 may be integrated in one housing. Further, at least a part of the functions of the information terminal 10, the server system 4, and the gateway device 7, for example, a part of the functions of the information terminal 10 may be realized by a cloud (cloud computing) or the like.

In the basic example, it is assumed that the information terminal 10 is a housing information board A1 having an intercom function of each exclusive unit 23. However, the information terminal 10 in the present disclosure is not limited to the housing information board A1. The information terminal 10 may be the lobby intercom 13 or the management room master unit 14. That is, in the intercom system 1, the distribution target of the update program may be the housing information board A1, the lobby intercom 13, and the management room master unit 14. Further, the information terminal 10 may be, for example, a HEMS controller that does not have an intercom function.

In the basic example, it is assumed that the specific function is a disaster prevention function in accordance with the restrictions of the Fire Service Act. However, the specific function is not limited to the disaster prevention function. For example, if there is a function for which it is not desirable to update the function later in the laws and regulations of each country, the information terminal 10 may be configured to handle the function as a specific function.

In the basic example, the server system 4 stores and manages a plurality of modules M1 (see FIG. 1) divided in functional units in the storage unit 43. Therefore, in the basic example, the gateway device 7 and the information terminal 10 receive the update program in the form divided by the function unit. However, the gateway device 7 or the information terminal 10 may have a function of dividing the update program into functional units.

By the way, the information terminal 10 includes a plurality of processing units C12 that process a plurality of functions, and the predetermined unit may be a processing unit unit corresponding to the plurality of processing units C12. That is, in the basic example, one processing unit C12 executes a plurality of functions. On the other hand, by providing a plurality of processing units C12, a plurality of functions may be processed in parallel. In this case, the first communication unit 101 and the second communication unit 102 of the information terminal 10 receive the update program in the form divided for each processing unit. With this configuration, while updating software related to a certain function, functions other than the function are less likely to interfere with the operation during execution, and the function update is further improved.
