  However, in the above-mentioned information system for collective housing, a system for providing local crime prevention information from the server device to the information terminal of each house has not been proposed until now, and provision of such crime prevention information is It was requested. An object of the present invention is to provide an information system for collective housing with a novel configuration that responds to such a demand.

In the information system for collective housing according to the present invention, in the information system for collective housing to connect a home information terminal of each home to an intercom line and transmit a call signal, each of the home information terminals is
When it is possible to connect to a wide area network via an intercom line and receive an area security information notification including a headline from a server apparatus on the wide area network, a security information notification screen prepared in advance as a local file and the headline Pop-up.

  In the present invention, it is possible to know the crime prevention information on the surrounding area by the information service through the interphone line, not by the broadcast such as the television. As a result, you can avoid going out and go out in consideration of the route, thus improving safety.

It is a system figure showing an example of a collective housing information system to which the present invention is applied. It is a front view of the example of a house information terminal. It is a flow figure showing the example of the basic operation of the intercom system for collective housing. (A)-(e) is an example of the various display screens in a house information terminal. (A)-(c) is a block diagram of the protocol stack of a house information terminal, a gateway apparatus, and a server apparatus, respectively. It is a format figure which shows the example of schematic structure of the communication data by an inter-phone protocol.

  The collective housing management system according to the present invention is based on an intercom system, to which a security service for fire and the like and an information service such as an electronic bulletin board are added.

  As shown in FIG. 1, in the system 1 illustrated as an embodiment, a line (interphone line) 12 in the ridge is laid from the control device 11 that controls the entire system to each house, common part, and manager's room A terminal device such as a home information terminal 13 is connected to this line via the branching unit 14.

  The in-building line 12 transmits a call signal, a video signal, a control signal, etc., which are indispensable in the intercom system, in a packet system. There is no particular limitation on the type of cable used for this line, and an inexpensive twisted pair cable may be used if a necessary communication band can be secured.

  In this example, 4 lines of in-building lines 12 are derived from the control device 11, whereby a line connecting the home information terminal 13, a line connecting the manager's room intercom 15, a line connecting the lobby intercom 16, and a gateway device The line connecting the 17 is separated. With such a configuration, for example, only the lobby intercom 16 can be supplied with power from the in-building line 12 or the like. However, since the control device 11 has a router function (hub function), it is not necessary to separate a line for each type of terminal device unless there is a special request. Also, the number of lines in the line is not particularly limited.

  The house information terminal 13 includes a communication unit 13a, a control unit 13b, a display unit 13c, an operation unit 13d, an audio unit 13e and the like, and a door phone 13h and a security sensor 13i are connected. The communication unit 13a performs signal transmission in accordance with the intercom protocol defined for the in-building line 12. The control unit 13b causes the browser 13f to display a top screen, a call screen, a security screen, an information service screen, and the like on the display unit 13c, and also controls lighting of the status lamp.

  As shown in FIG. 2, the display unit 13 c is, for example, a color touch panel, and can display various fonts, images, and the like. The audio unit 13e is composed of a speaker, a microphone and the like. The operation unit 13 d includes physical buttons or software buttons appropriately displayed on the touch panel, and configures a time zone setting unit 13 g that sets a time zone for permitting pop-up display of crime prevention information and the like. Here, the recovery / alarm stop button, the fire confirmation button, the menu button, the end button, the unlock button, and the call button are provided as physical buttons, but a lamp indicating arrival information is incorporated in the menu button It is also good.

  The basic screen of the house information terminal 13, ie, the top screen, the call screen, and the security screen, is prepared as a local document in the house information terminal 13.

  The gateway device 17 relays signal transmission across the in-building line 12 and the wide area network 2, specifically, signal transmission between the home information terminal 13 and the server device 3. Therefore, the communication unit 17 a corresponding to the in-building line 12, the relay unit 17 b for converting the protocol bi-directionally between the in-building line 12 and the wide area network 2, and the communication unit 17 c corresponding to the wide area network 2 are provided. The gateway device 17 also includes a web server unit 17 d that provides a home page for maintenance of the system 1. The maintenance home page is accessed by the maintenance terminal 4 or the like detachably connected to the gateway device 17. In addition, although URL of the server apparatus 3 is preset by the dwell unit information terminal 13, rewriting is also possible through the website for maintenance.

  The server device 3 includes a communication unit 3a corresponding to the wide area network 2, a web server unit 3b, a storage unit 3c, and the like. The web server unit stores articles of an electronic bulletin board, crime prevention information and the like in a storage unit, and provides HTML data and image files constituting them to a home information terminal. In addition, house identification information and the like are also stored in the storage unit.

  Here, the basic operation of the system 1 will be briefly described. That is, the system 1 provides an interphone function as one of the main functions. That is, when a calling operation is performed by designating a room number by the lobby intercom 16, a ringing tone sounds at the house information terminal 13 of the corresponding house and a video of the visitor is displayed on the display unit 13c. When a response operation is performed at the home information terminal 13, an interactive call with the lobby intercom 16 becomes possible. If the housing information terminal 13 performs a predetermined operation, the electric lock 18 on the lobby door can be unlocked. In addition, a call communication between the housing information terminal 13 and the manager's room interphone 15 and a call communication between the housing information terminals 13 are also provided. These mutual calls are cut off by one of the closing operations or the elapse of a predetermined time.

  The system 1 also has a security function. For example, when the security sensor 13i in the house operates, the house information terminal 13 sounds an alarm sound. The security sensor 13i can also be turned on and off by mode switching operation. The manager's room intercom 15 has a function as an alarm monitoring board. That is, the manager's room intercom 15 monitors the operation state of the security sensor 13i in the in-building common area and each house, the operation state of the house information terminal 13, etc. and detects an abnormality. An acoustic device (not shown) and the house information terminal 13 of each house are operated to perform a district ringing, an entire ridge ringing, and the like.

  In addition, the system 1 has an information service function of distributing security information of the area. Since this point is a big feature, the information service will be described in detail below. In summary, when crime prevention information is newly registered in the server device 3, a notification signal is distributed from the server device 3 to each home information terminal 13 to cause a pop-up display, and in response to a request from the home information terminal 13. , Is to return the requested crime prevention information. In this way, by notifying the local crime prevention information timely, it is possible to raise the resident's awareness of crime prevention.

  The basic operation of the system 1 will be described below with respect to distribution and display of crime prevention information.

  The server device 3 appropriately registers crime prevention information to be distributed to the house information terminal 13 by information communication with a service provider or the like. The crime prevention information is composed of a headline and an article text, and identification information (URL) is assigned. As a matter of course, the security information registered here may be a target for the neighborhood area where the apartment house is located.

  When such crime prevention information is registered, the server device 3 generates a corresponding crime prevention information notification, and distributes the notice to each housing information terminal 13. The crime prevention information notification includes a headline of crime prevention information and identification information. When receiving the crime prevention information notice from the server device 3, the house information terminal 13 pops up and displays a crime prevention information notice screen. The alarm sound may be sounded at the timing of the pop-up display. On such a crime prevention information notification screen, for example, a headline such as "a snatching event has occurred" is displayed (see FIG. 4 (f)).

  The security information notification screen may be automatically deleted when a predetermined time elapses after pop-up display, or may be deleted when a predetermined operation, for example, an operation of a confirmation button prepared in the security information notification screen is received. . Also, pop-up display may be performed only during the activity time zone of the resident. In this case, the house information terminal 13 determines whether to display the crime prevention information notification screen in a pop-up manner based on the current time. The resident's activity time zone may be set uniformly at all the house information terminals 13, for example, from 6 am to 10 pm and may not be changeable, and the time zone setting of each house information terminal 13 It may be freely changed by the operation of the part 13g. With such a configuration, there is no problem that pop-up display prevents sleep.

  In addition, when the confirmation button in the crime prevention information notification screen is operated or when a predetermined procedure is performed, the house information terminal 13 transmits a request signal including identification information of the crime prevention information to the server device 3. The article text of the crime prevention information sent back from the server device 3 is displayed. For example, add the text of the article to the headline as described above, “about □ 2:00 pm on the street of ○○ City △, female of a nearby restaurant employee who was walking and walking ), But a man holding a small bike was robbed of a bag of about ¥ 200,000 in cash he had in his hand. ×× The prefectural police is investigating as a snatching case. ” See FIG. 4 (d)).

  If such an information service is provided, the resident can know the occurrence of a crime etc. in the nearby area in a timely manner without using a broadcast such as television. And, because it is possible to refrain from going out to the vicinity of the incident site or to go out by selecting a safe route, the security is improved.

  For such an information service, signal transmission according to a predetermined protocol is required between the home information terminal 13 and the server device 3. For example, HTTP may be adopted as the protocol. However, HTTP is a simple protocol in which an HTTP response is returned from the server in response to an HTTP request of the client, and the server apparatus 3 can not voluntarily transmit information. Therefore, we propose a method in which a client polls a server in order to realize a function substantially equivalent to sending information from the server. That is, the house information terminal 13 periodically transmits a dummy HTTP request to the server device 3, and the server device 3 appropriately embeds information to be transmitted in the HTTP response.

  Specifically, when crime prevention information to be delivered is registered in the home information terminal 13, the server device 3 generates a crime prevention information notification, and waits for an HTTP request from the home information terminal 13. Then, when an HTTP request specifying identification information is sent from the house information terminal 13, the server device 3 sends back an HTTP response including the corresponding crime prevention information notification. The security information notification includes a URL identified as identification information of the security information. If there is no notification of crime prevention information to be returned, an empty HTTP response is returned.

  In addition, when the server device 3 receives an HTTP request including the URL of the crime prevention information from the house information terminal 13, the server device 3 sends back an HTTP response including the crime prevention information specified by the URL.

  FIG. 3 shows the basic operation regarding distribution of crime prevention information of the system 1 in time series.

  At time T1 to T2, the home information terminal 13 periodically transmits a dummy HTTP request by polling. However, at this time, since there is no security information notification to be sent to the server device 3, an empty response is returned.

  At time T3, crime prevention information is newly registered in the server device 3, and a crime prevention information notification is generated.

  At time T4, in response to the dummy HTTP request from the home information terminal 13, the server device 3 sends back an HTTP response including the crime prevention information notification.

  At time T5, the home information terminal 13 pops up and displays a crime prevention information notification screen based on the received crime prevention information notification.

  At time T6, the house information terminal 13 receives the confirmation operation on the crime prevention information notification screen, transmits an HTTP request including the URL of the crime prevention information to the server device 3, and the server device 3 includes the corresponding crime prevention information. The HTTP response is sent back.

  At time T7, the house information terminal 13 displays the article text of the received crime prevention information.

  The server device 3 may hold a list of stored crime prevention information, and when the crime prevention information is newly registered, the crime prevention information list may be updated. In this list, for each piece of crime prevention information, the headline and the identification information are described correspondingly.

  On the other hand, when the home information terminal 13 receives an operation from the top screen according to a predetermined procedure, the home information terminal 13 requests the server apparatus 3 for a crime prevention information list, and displays the crime prevention information list acquired from the server apparatus 3 on the display unit. At this time, a selection button is disposed on the article list screen for each piece of crime prevention information, and a selection operation is received. For example, the crime prevention information list may be composed of HTML documents, and a script for accepting selection operation may be included therein. When the housing information terminal 13 receives the selection operation of the crime prevention information on the article list screen, the residence information terminal 13 transmits the request signal including the identification information of the selected crime prevention information to the server device 3 and the crime prevention information acquired from the server device 3 Display

  With such a configuration, the resident can freely read even out-of-date security information, so it is safe even if he has been away for a while.

  Although (a)-(f) of FIG. 4 are the examples of the display screen in the house information terminal 13, Japanese is set as a classification of a display language.

  FIG. 4A shows an example of the top screen W1. In the upper part, a notification icon and a weather icon are arranged. In the middle part, a state icon (at home, going out, etc.) indicating the current security mode and a mode switching button are arranged. In the lower part, a call / message button, an information button, and a recording management button are arranged.

  FIG. 4B shows an example of the information service screen W2. This screen is called by operating the information button on the top screen. A button for calling the subcategory of the information service is arranged. Security information is provided as one of the categories.

  FIG. 4C shows an example of the article list screen W3 limited to the crime prevention information category. This screen is called by the operation of the crime prevention information button on the information service screen. The headlines of the crime prevention information are displayed in a list, and the detail button (selection button) is arranged corresponding to each of them.

  FIG. 4D shows an example of the crime prevention information screen W4. This screen is called by the selection operation on the display screen of the article list.

  FIG. 4E shows an example of the crime prevention information notification screen W5. This screen is popped up for a predetermined time when the crime prevention information notification is received while the top screen is being displayed (including turning off). The headline of crime prevention information is described, and the confirmation button is arranged. By the operation of the confirmation button, the crime prevention information screen W4 shown in FIG. 4 (d) is called.

  Among these screens, the screen information of the top screen W1 and the crime prevention information notification screen W5 is prepared in advance as a local file in the house information terminal 13. The other information service screen W2, the article list display screen W3, and the article text display screen W4 are stored in the server device 3 and are read by the browser 13f of the house information terminal 13.

  In this embodiment, the crime prevention information and the crime prevention information notification are transmitted by HTTP. Hereinafter, a mechanism of signal transmission by HTTP will be described in detail.

  As shown to (a)-(c) of FIG. 5, the house information terminal 13, the gateway apparatus 17, and the server apparatus 3 each comprise protocol stack PS. The protocol stack PS has a conceptual hierarchical structure, and at the time of data transmission, communication data sequentially flows from the upper layer to the lower layer and is output to the in-building line 12. At that time, necessary headers are appropriately added in each layer. On the other hand, at the time of reception, communication data input from the in-building line 12 sequentially flows from the lower layer toward the upper layer. At this time, headers that are no longer needed in each layer are removed.

  In the protocol stack PS of the home information terminal 13, the application layer is placed at the top, and the intercom protocol layer, the TCP / UDP layer, the IP layer, the data link, and the physical layer are placed below it in that order.

  The application layer includes a control program for the home information terminal 13 and a browser program for displaying an information service screen.

  The intercom protocol layer is controlled by the application layer, and transmits various command signals and response transmissions with the application layer of the information terminal of the communication partner.

  Here, the intercom protocol is a unique protocol defined for the in-building line 12, and the command signal and the response signal mutually transmitted between the information terminals are transmission source identification information, transmission destination identification information, command code , And command parameters etc. have a field-partitioned format. The identification information may be a local IP address or unique identification information. Since the browser 13 f of the home information terminal 13 transmits an HTTP message (request, response), a command signal and a response signal of the interphone protocol require a mechanism for including the HTTP message inside. This can be realized, for example, by defining a code indicating an HTTP message in a command signal or response signal of the intercom protocol, and embedding the body of the HTTP message in the command parameter (see FIG. 6).

  The TCP / UDP layer controls signal transmission defined between an application at a source information terminal and an application at a destination information terminal. At the time of transmission, a header including information for recovering a communication error and a port number for specifying an application of a transmission source and a transmission destination is added to communication data of the intercom protocol in this layer. It is desirable that the control signal such as the ringing signal be transmitted by TCP with a certain but somewhat low speed, and the audio signal and the video signal be transmitted by a high speed but uncertain UDP. Audio signals and video signals may be transmitted in a form encoded by a predetermined codec.

  The IP layer controls relayable signal transmission defined between the transmission source information terminal and the transmission destination information terminal. At the time of transmission, a header including the transmission source, the local IP address of the transmission destination, etc. is added here.

  The physical and data link layers perform signal transmission between information terminals physically connected by cables. In particular, in the system 1, since the in-building line 12 is configured by a twisted pair line, a communication packet (IP packet) specified in the IP layer is transmitted by differential serial communication. Serial communication may be synchronous or asynchronous.

  In the protocol stack PS of the gateway device 17, a relay program for interconversion between the intercom protocol and the wide area network protocol is placed at the top. Below that, there is an interphone protocol layer, a TCP / UDP layer, an IP layer, a data link, an in-building line side stack consisting of a physical layer, an HTTP layer, a TCP / UDP layer, an IP layer, a data link, a wide area consisting of physical layers Network side stacks are arranged in parallel.

  The protocol stack PS of the server device 3 has a web server program providing HTML files of electronic bulletin boards and the like, under which HTTP layer, TCP / UDP layer, IP layer, data link, physical layer are placed .

  When the above protocol stack PS is configured, the HTTP request transmitted from the browser program of the home information terminal 13 is transmitted to the gateway device 17 through the in-building line 12 in a form incorporated in the communication data of the interphone protocol. Ru. The relay program of the gateway device 17 extracts the HTTP request from the communication data of the intercom protocol, and reconstructs the normal HTTP request. The HTTP request reconstructed by the gateway device 17 is transmitted to the server device 3 through the wide area network 2.

  On the other hand, the HTTP response transmitted from the server device 3 is transmitted to the gateway device 17 through the wide area network 2. The relay program of the gateway device 17 generates communication data of the intercom protocol incorporating the HTTP response. The communication data generated by the gateway device 17 is transmitted to the home information terminal 13 through the in-building line 12. The control program of the home information terminal 13 extracts the HTTP response from the communication data and passes it to the browser program.

  Such a procedure enables transmission of an HTTP request and response between the home information terminal 13 and the server device 3 through the in-building line 12.

  FIG. 6 is a format diagram showing a schematic structure of communication data according to the intercom protocol. Thus, as described above, the HTTP message is accommodated in the interphone protocol communication data as a command parameter following the identification code (command code) indicating the HTTP message. This communication data 20 is further divided into smaller packets by the data link / physical layer and transmitted by the in-building line 12.
