It is explanatory drawing of the data table used for the same as the above. FIG. 10 is a sequence diagram for explaining the operation of the third embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
Embodiment 1 of this invention is demonstrated based on FIGS. 1-3. FIG. 1 is a system configuration diagram showing the overall configuration of the present embodiment. Although only one dwelling unit HM is shown in FIG. 1, it goes without saying that the home display system provided in the dwelling unit HM may be applied to a plurality of dwelling units. Moreover, although this embodiment is a form which applied the technical idea of this invention to the dwelling unit HM like a detached house, it cannot be overemphasized that the technical idea of this invention may be applied to each dwelling unit of an apartment house.

  The interior of the dwelling unit HM is partitioned into a plurality of spaces (living room, bedroom, kitchen, washroom, bathroom, toilet, hallway, entrance, etc.) by walls. Display control units 2a to 2c, human sensors 3a to 3c, and setting switches 4a to 4c are arranged. Further, individual position information is assigned to each of the spaces Ra, Rb, and Rc in the dwelling unit HM in order to identify each space. The display devices 1a are not necessarily installed in all spaces in the dwelling unit HM, but may be installed in a space required by a resident.

  The display controllers 2a to 2c in the spaces Ra to Rc have a Web client function, and the display controllers 2a to 2c and the content server 5 are connected to a home network NT1 constructed in the dwelling unit HM. A content server 5 having a Web server function is installed in the dwelling unit HM. The display controllers 2a to 2c and the content server 5 in the dwelling unit HM are connected to a wide area communication network NT2 such as the Internet via a router 6.

  Further, reference numeral 7 in FIG. 1 denotes a content server operated by a content provider, and the content server 7 on the provider side can be accessed from the display control unit 2a of each dwelling unit and the content server 5 via the wide area network NT2. ing. Content that is not stored in the content server 5 of each dwelling unit HM is provided from the content server 7 on the provider side to the display control unit 2a.

  Next, each component of the home display system will be described. In the following description, the individual display devices are described as display devices 1a, 1b, and 1c, and the description common to all the display devices is expressed as display device 1. Regarding the display control units 2a to 2c, the human sensors 3a to 3c, and the setting switches 4a to 4c, the notation of the symbols is similarly distinguished between the case where the individual explanation is given and the case where the overall explanation is given. .

  The display device 1 (1a to 1c) is composed of a control panel that monitors and controls the operation of equipment (electric lock device, lighting equipment, security system, etc.) installed in the dwelling unit HM, or a television set. A display monitor for displaying content to be provided is provided. In the display device 1, when the content is displayed for a certain period of time, the screen display is paused and the sleep state is shifted to reduce the power consumption. When the activation signal is input from the display control unit 2 to the display device 1 in the sleep state, the display device 1 returns from the sleep state and displays the content specified by the display control unit 2. Note that the content provided to the residents is, for example, a Web page provided from the content server 5, and may be a TV program or the like when the display device 1 is a TV.

  The human sensor 3 (3a to 3c) includes, for example, a pyroelectric infrared detection element that detects the presence or absence of a person in the detection area by detecting heat rays emitted from the human body. When detecting the presence of a person in the space where the human sensor 3 is installed, the human sensor 3 outputs a human body detection signal as a trigger signal to the display control unit 2 installed in the same space.

  The display control part 2 (2a-2c) controls the display content of the display apparatus 1 installed in the same space. Each display control unit 2 is connected to a setting switch 4 (4a to 4c) for setting position information of a space where the corresponding display device 1 exists. The setting switch 4 serving as the position information setting unit is formed of, for example, a dip switch. For example, the setting switch 4 is used during construction, for example, the spaces Ra to Rc where the corresponding display device 1 exists, that is, the spaces Ra to which the device itself is installed A number (positional information) assigned to Rc is set.

  Each display control unit 2 stores a data table TB1 (see FIG. 3A) in which the position information of each of the spaces Ra to Rc is associated with the address information of the content to be displayed when the display device 1 is activated. 9 (storage unit). In the memory 9, it is not necessary to store the position information of each space and the address information of the content to be displayed at the time of activation as the data table TB1, and it is only necessary to store the position information and the address information in association with each other.

  Next, in this in-home display system, the display control unit 2 receives the trigger input, activates the display device 1 in the sleep state, and causes the display device 1 to display an initial screen according to the installation location with reference to FIG. This will be described with reference to FIG.

  When there is no resident in the space Ra and the display device 1 installed in the space Ra is not used, the display device 1 is switched to the sleep state by turning off the power of the monitor (see FIG. 2). S11). When a resident enters the space Ra in this state, the human sensor 3a detects a resident (S12 in FIG. 2) and outputs a human body detection signal to the display control unit 2a (S1 in FIG. 1, FIG. 2). S13).

  When the human body detection signal is input as a trigger signal from the human sensor 3a, the display control unit 2a outputs a start command for turning on the display monitor to the display device 1a in the same space Ra (S2 in FIG. 1). , S14 in FIG. The display device 1a that has received the activation command turns on the display monitor (S15 in FIG. 2), and then returns a display monitor activation notification to the display control unit 2a with the screen size of the display monitor as an argument (FIG. 2). 1 S3, FIG. 2 S16). The reason why the display control unit 2 returns the screen size is because the contents provided from the content servers 5 and 7 differ depending on the resolution of the display monitor such as VGA (Video Graphics Array) or QVGA (Quarter VGA). is there.

  When receiving the activation notification from the display device 1a, the display control unit 2a reads a number (position information) indicating the installation location of the display device 1a from the setting switch 4a (S17 in FIG. 2). Further, the display control unit 2a refers to the data table TB1 based on the read number and acquires address information of the content to be displayed (S18 in FIG. 2). Upon obtaining the address information, the display control unit 2a uses the address information and accesses the content server 5 (or 7) corresponding to the address information using the screen size received in S16 as an argument (S19 in FIG. 2).

  When accessed from the display control unit 2a, the content server 5 (or 7) storing the target content acquires the screen size information and address information transmitted from the display control unit 2a (S20 in FIG. 2). The content server 5 (or 7) determines a Web page to be transmitted based on the screen size information and the address information, and transmits data of the Web page to the display control unit 1a (S21 in FIG. 2). ). The display control unit 2a transmits this Web page to the display device 1a (S22 in FIG. 2), and the display device 1a displays the Web page transmitted from the display control unit 2a (S24 in FIG. 2). Further, the display control unit 2a activates a timer (not shown) that counts a predetermined display time after transmitting the Web page (S23 in FIG. 2). When the timer completes the display time counting operation (S25 in FIG. 2), the display control unit 2a transmits a control command (sleep command) for turning off the power of the display monitor to the display device 1a (S26 in FIG. 2). . In the display device 1a, if any operation such as screen switching is not performed on the display device 1a side until the sleep command is received from the display control unit 2a, the display monitor is turned off and enters the sleep state. (S27 in FIG. 2).

  In this way, when the display device 1 in the sleep state is activated, the display control unit 2 reads address information corresponding to the space in which the display device 1 to be controlled exists from the data table TB1. Then, the display control unit 2 accesses the content server 5 (or 7) in which the content is stored based on the read address information, and displays the content transmitted from the content server 5 (or 7). It is displayed on the device 1. When content is distributed from the content server 7 outside the dwelling unit to the display device 1 via the Internet, the content server 5 provided in the dwelling unit HM serves as a proxy server.

  As a result, when the display device 1 is activated from the sleep state, content set in advance according to the installation location is displayed as an initial screen, and thus the content at the installation location is provided to the dweller. be able to. For example, if the address information of the Web page for searching the cooking menu is set in association with the kitchen number in the data table TB1, the operation of switching to the Web page for obtaining information necessary for the kitchen can be omitted. If the address information of the web page displaying the weather forecast in association with the entrance number or the web page displaying the transportation timetable is set in the data table TB1, information necessary for going out can be obtained. Therefore, it is possible to omit an operation for switching to a Web page. It should be noted that the content required in each space in the dwelling unit HM is considered to differ depending on the resident, but if the resident sets address information of desired content in association with each space, the display device 1 in each space. Desired content can be displayed at the time of activation. Therefore, it is not necessary for the resident to perform the screen switching operation from the initial screen of the display device 1 to display the desired content, and the display content switching operation can be omitted.

  Further, when the display control unit 2 activates the display device 1 in the sleep state and displays the initial screen according to the installation location, the display control unit 2 stops the display of the display device 1 when a predetermined display time has elapsed. However, this display time may be set to a different time depending on the installation location. The plurality of spaces in which the display device 1 is installed pay attention to the dwelling time of dwellers, and the staying time is relatively short compared to a staying type space (for example, living room, bedroom, kitchen, etc.). It is classified as a pass-through space (for example, corridors, stairs, entrances, etc.). In the display control unit 2, the display time of the display device 1 in the passing type space is set to be shorter than that of the display device 1 in the stay type space. For example, in the display device 1 in the stay type space, the display time is set to about 180 seconds, and in the display device 1 in the passage type space, the display time is set to about 10 seconds.

  Thereby, in the case of the display device 1 in the pass-through space, since the resident passes through in a short time, the power consumption of the display device 1 can be reduced by setting the display time short. Further, in the case of the display device 1 in the stay-type space, the resident stays for a long time, so that the initial screen content can be displayed for a long time by setting the display time longer. There is an effect that it is difficult to overlook.

  In the present embodiment, the content displayed as the initial screen can be set according to the space in which the display device 1 is installed. However, as the initial screen, the pass-through space and the stay-type space are used. The content of the displayed content may be different. In the pass-through space, it is considered that the time for viewing the display on the display device 1 is shorter than that in the stay-type space. Therefore, content in which the minimum necessary information is simply displayed (such content is referred to as pass-through content). Preferably). On the other hand, in the stay-type space, the display contents can be viewed for a long time compared to the transit-type space, so that more information can be provided to the inhabitants. It is preferable to provide large contents (such contents are called stay-type contents). Thus, in the data table TB1, it is preferable that the address information of the stay-type content is registered corresponding to the stay-type space, and the address information of the pass-type content is registered corresponding to the pass-type space, which is suitable for the installation space. Content can be provided.

  In this embodiment, the data table TB1 is held in the memory 9 of the display control unit 2, and the display control unit 2 refers to the data table TB1 based on the position information of the display device 1 and addresses according to the position information. Although the information is acquired, information in which the location information of the display device 1 is associated with the address information of the content may be stored in the storage units of the content servers 5 and 7.

  Furthermore, in the present embodiment, when a human body detection signal is input as a trigger signal, the display control unit 2 activates the display device 1, but a remote control transmitter (not shown) for performing a remote control operation of the display device 1. The remote control signal transmitted from (1) may be used as the trigger signal. That is, the display control unit 2 is provided with a remote control receiving unit 8 that receives a radio signal (for example, an infrared signal) transmitted from a remote control transmitter, and receives a remote control signal transmitted from the remote control transmitter in response to a user operation. The display device 1 may be activated based on the received signal.

  In the memory 9, information in which the address information of the Web page is associated with the position information of the space in which the display device 1 exists is registered. However, the content to be displayed at startup is limited to the Web page. Instead, a television broadcast screen may be displayed. FIG. 3B shows the setting contents of the data table TB1 held by the display control unit 2. In the space where the numbers (position information) are “03” and “04” in the dwelling unit HM, instead of the address information of the Web page. And TV input are set in association with each other.

  Thereby, when the display device 1 in these spaces “03” and “04” is activated from the sleep state, the display control unit 2 that controls the display of the display device 1 displays a predetermined television screen on the display device 1. Can be made. Note that the TV image displayed at the time of startup may be a TV image of a channel that was displayed before switching to the sleep state, or a TV image of a preset channel.

(Embodiment 2)
A second embodiment of the present invention will be described with reference to FIGS. In the first embodiment, the content to be displayed at the time of activation is changed depending on the space in which the display device 1 exists. In the present embodiment, the activation is performed according to the space in which the display device 1 exists and the time zone at the time of activation. Sometimes the content to be displayed has changed. Since the system configuration of the present embodiment is the same as that of the first embodiment, common constituent elements are denoted by the same reference numerals, illustration and description thereof are omitted, and only characteristic portions of the present embodiment will be described.

  The content servers 5 and 7 have a clocking function for clocking the current time, and when accessed from the display control unit 2, a function for changing the address information of the link destination according to the current time obtained by the clocking function It has.

  The content servers 5 and 7 include a storage unit (not shown) made of a rewritable nonvolatile semiconductor memory (EEPROM or the like). In this storage unit, there is a data table TB2 in which the address information of each space set in the data table TB1 is associated with the address information for changing the link destination of this address information according to the time zone. It is remembered.

  FIG. 5 shows an example of the data table TB2. In this data table TB2, a flag indicating the presence / absence of setting of contents by time zone is registered for each address information of each space set in the data table TB1. In the data table TB2 shown in FIG. 5, midnight (0 to 6), morning (6 to 9), daytime (9 to 17:00), evening (17:00 to 19:00), night (19:00 to Address information is set for five time zones (24:00). Note that the above data table TB2 is an example of how to divide the time zone, and can be appropriately changed according to the behavior style of the resident.

  Here, when the content flag for each time zone is not set, the content servers 5 and 7 use the address information of each space set in the data table TB1 regardless of the time zone. In the example of FIG. 5, for the address information for the installation space with the numbers (position information) “03” and “04”, the flag of the content by time zone is not set, so the same address information regardless of the time zone Is used.

  On the other hand, when the flag for content by time zone is set, link destination address information is set for each time zone. For example, for the address information “http: //.. ./Loc01” for the installation space with the number “01”, the link destination is set to “http: //.../loc01/mid” in the midnight time zone. The link for the morning time zone is set to “http: //.../loc01/mor”, and the link destination for the daytime time zone is set to “http: //.../loc01/day”. Furthermore, the evening time zone link destination is set to "http: //.../loc01/eve", and the evening time zone link destination is set to "http: //.../loc01/nig".

  Next, in this in-home display system, the display control unit 2 receives the trigger input, activates the display device 1 in the sleep state, and causes the display device 1 to display an initial screen according to the installation location and the time zone. Will be described with reference to FIG.

  When there is no resident in the space Ra and the display device 1a installed in the space Ra is not used, the display device 1a is switched to the sleep state by turning off the power of the monitor (see FIG. 4). S31). When a resident enters the space Ra in this state, the human sensor 3a detects a resident (S32 in FIG. 4) and outputs a human body detection signal to the display control unit 2 (S33 in FIG. 4).

  When the human body detection signal is input from the human sensor 3a as a trigger signal, the display control unit 2a outputs an activation command for turning on the display monitor to the display device 1a in the same space Ra (S34 in FIG. 4). ). The display device 1a that has received the activation command turns on the display monitor (S35 in FIG. 4), and then returns a display monitor activation notification to the display control unit 2a using the screen size of the display monitor as an argument (FIG. 4). 4 S36).

  When receiving the activation notification from the display device 1a, the display control unit 2a reads a number (position information) indicating the space in which the display device 1a exists from the setting switch 4a (S37 in FIG. 4). Further, the display control unit 2a refers to the data table TB1 based on the read number, and acquires address information of content to be displayed at the time of activation (S38 in FIG. 4). Upon obtaining the address information, the display control unit 2a uses the address information and accesses the content server 5 (or 7) corresponding to the address information using the screen size received in S36 as an argument (S39 in FIG. 4).

  When accessed from the display control unit 2a, the content server 5 (or 7) that stores the target content acquires the screen size information and address information transmitted from the display control unit 2a (S40 in FIG. 4). The content server 5 (or 7) acquires the time accessed from the display control unit 2a by the time counting function (S41 in FIG. 4), and creates the data table TB2 based on the address information and time information acquired in S40. Referring to the address information of the link destination is determined (S42 in FIG. 4). For example, if the address information transmitted from the display control unit 2a is "http: //.../loc01" and the accessed time is 8 o'clock, the address information "http: // … / Loc01 / mor ”is determined.

  When the link destination is determined in this way, the web page of the link destination determined in S42 is transmitted from the content server 5 (or 7) to the display control unit 2a (S43 in FIG. 4). The display control unit 2a transmits this Web page to the display device 1a (S44 in FIG. 4), and the display device 1a displays the Web page transmitted from the display control unit 2a (S46 in FIG. 4). Further, the display control unit 2a activates a timer (not shown) that counts a predetermined display time after transmitting the Web page (S45 in FIG. 4). When the timer completes the display time counting operation (S47 in FIG. 4), the display control unit 2a transmits a control command (sleep command) for turning off the power of the display monitor to the display device 1a (S48 in FIG. 2). In the display device 1a, if any operation such as screen switching is not performed on the display device 1a side until the sleep command is received from the display control unit 2a, the display monitor is turned off and enters the sleep state. (S49 in FIG. 4).

  As described above, when the display device 1 in the sleep state is activated, the display control unit 2 reads the address information corresponding to the position information of the space where the display device 1 to be controlled exists from the data table TB1. When the display control unit 2 accesses the content server 5 (or 7) based on the read address information, the content server 5 (or 7) refers to the data table TB2 based on the accessed time zone. Change the link destination address. That is, the content servers 5 and 7 have a function of changing the content linked to the address information according to the access time from the display control unit 2, and the display device 1 has a function according to the setting of the data table TB2. The content with the changed address information is displayed.

  As a result, when the display device 1 is activated from the sleep state, content determined in accordance with the installation location and the activation time is displayed as the initial screen, so that the content suitable for the installation location and the activation time is displayed. It can be provided to residents. Here, since the data table TB2 defining the content address for each time zone is given to the content servers 5 and 7, when the contents of the data table TB2 are changed, only the content servers 5 and 7 What is necessary is just to rewrite the contents. Needless to say, the display control unit 2 may have a data table TB2 for setting content addresses according to time zones in addition to the data table TB1. In the present embodiment, in the data tables TB1 and TB2, the address information of the Web page is set as the content to be displayed at the time of startup, but a television broadcast screen may be set as the content at the time of startup. Also, when the television broadcast screen is set as the start screen, the television broadcast screen may be individually set in each time zone in the data table TB2, and the television broadcast suitable for each time zone may be set. This screen (TV screen) can be presented to residents.

  Depending on the installation location of the display device 1, it may not be necessary to change the startup screen according to the time zone. For the display device 1 in such an installation location, the flag for content by time zone is not set. As long as the same content is displayed.

(Embodiment 3)
A third embodiment of the present invention will be described with reference to FIG. In the first and second embodiments, the display control unit 2a has the data table TB1 in which the content to be displayed at the time of startup is set. In the present embodiment, the data table TB1 is a content installed in the home. The server 5 has it. In addition, the same code | symbol is attached | subjected to the component which is common in the home display system of Embodiment 1, 2, and the description is abbreviate | omitted and the characteristic part of this embodiment is demonstrated below.

  A memory (not shown) of the content server 5 stores a data table TB1 that stores content information to be displayed when the display device 1 is activated. FIGS. 3A and 3B are examples of the data table TB1, in which position information indicating each space in the dwelling unit HM is associated with information on content to be displayed when the display device 1 existing in each space is activated. Is set. As content information to be displayed at the time of startup, Web page address information, television broadcast television image information, and the like are set.

  Next, in this home display system, the display control unit 2 activates the sleep display device 1 in response to the trigger input, and displays an initial screen corresponding to the installation location on the display device 1 as shown in FIG. The description will be given with reference.

  When there is no resident in the space Ra and the display device 1 installed in the space Ra is not used, the display device 1 is switched to the sleep state by turning off the power of the monitor (see FIG. 6). S11). When a resident enters the space Ra in this state, the human sensor 3a detects a resident (S12 in FIG. 6) and outputs a human body detection signal to the display control unit 2a (S13 in FIG. 6).

  When the human body detection signal is input from the human sensor 3a as a trigger signal, the display control unit 2a outputs an activation command for turning on the display monitor to the display device 1a in the same space Ra (S14 in FIG. 6). ). The display device 1a that has received the activation command turns on the display monitor (S15 in FIG. 6), and then returns a display monitor activation notification to the display control unit 2a using the display monitor screen size as an argument (FIG. 6). 6 S16).

  When the address information of the content to be displayed when the display device 1 is activated is not set in the display control unit 1, when the display control unit 2a receives the activation notification from the display device 1a, the content information is acquired. .

  That is, the display control unit 2a reads a number (position information) indicating the installation location of the display device 1a from the setting switch 4a (S17 in FIG. 6), and sends a signal for requesting address information of the initial screen using this number as an argument. It transmits to the content server 5 (or 7) (S28 of FIG. 6). When the content server 5 (or 7) receives the address information request signal from any of the display control units 2a, the content server 5 (or 7) refers to the data table TB1 based on the installation location number (position information) sent together with the request signal. Then, the address information of the content of the initial screen is acquired (S29 in FIG. 6). Further, the content server 5 (or 7) returns the address information acquired in S29 to the display control unit 2a that is the transmission source of the request signal (S30 in FIG. 6). When the address information is returned from the content server 5 (or 7), the display control unit 2a that has transmitted the request signal stores the address information in the memory 9 (storage unit). Once the address information is acquired from the content server 5 (or 7), the display control unit 2a uses the address information stored in the memory 9 and the content server 5 (or 7) using the screen size received in S16 as an argument. Is accessed (S19 in FIG. 6).

  When accessed from the display control unit 2a, the content server 5 (or 7) storing the target content acquires the screen size information and address information transmitted from the display control unit 2a (S20 in FIG. 6). The content server 5 (or 7) determines a Web page to be transmitted based on the screen size information and the address information, and transmits data of this Web page to the display control unit 2a (S21 in FIG. 6). . The display control unit 2a transmits this Web page to the display device 1a (S22 in FIG. 6), and the display device 1a displays the Web page transmitted from the display control unit 2a (S24 in FIG. 6). Further, the display control unit 2a activates a timer (not shown) that counts a predetermined display time after transmitting the Web page (S23 in FIG. 6). When the timer completes the display time counting operation (S25 in FIG. 6), the display control unit 2a transmits a control command (sleep command) for turning off the power of the display monitor to the display device 1a (S26 in FIG. 6). . In the display device 1a, if any operation such as screen switching is not performed on the display device 1a side until the sleep command is received from the display control unit 2a, the display monitor is turned off and enters the sleep state. (S27 in FIG. 6).

  As described above, when there is a transmission request for the address information of the initial screen from the display control unit 2 that controls the display of the display device 1, the content server 5 (or 7) displays the address information according to the position where the display device 1 exists. Is read from the data table TB1 and returned to the requesting display control unit 2. The display control unit 2 stores the address information returned from the content server 5 (or 7) in the memory 9, accesses the content server 5 (or 7) again, and transmits it from the content server 5 (or 7). The displayed content is displayed on the display device 1.

  As a result, when the display device 1 is activated from the sleep state, content set in advance according to the installation location is displayed as an initial screen, and thus the content at the installation location is provided to the dweller. be able to. In addition, when the display control unit 2 acquires the address information of the content to be displayed at the time of activation by the processing from S17 to S29 in FIG. 6, the display control unit 2 stores this information in the memory 9. Then, when a trigger signal is input thereafter, the display control unit 2 uses the address information read from the memory 9 to acquire corresponding content information from the content server 5 (or 7). The trouble of acquiring address information each time can be eliminated.

  In addition, only the content server 5 (or 7) has the data table TB1 that defines the correspondence between each space in the dwelling unit HM and the content address displayed at the time of activation from the sleep state. When it is desired to change the contents of the data table TB1, if each display control unit 2 has the data table TB1, it is necessary to rewrite the contents of the data table TB1 in all the display control units 2. On the other hand, in the present embodiment, the content server 5 (or 7) is provided with the data table TB1.

  As a result, only the content server 5 (or 7) needs to rewrite the contents of the data table TB1, so that it is possible to easily cope with the setting change of the data table TB1.

  Incidentally, in each of the above-described embodiments, the position information of the corresponding display device 1 is set using the setting switches 4a to 4c. However, the position information of the display device 1 is set by a method other than the setting by the setting switch 4a. May be. For example, a location where the display device 1 is used is determined in advance, and position information indicating the location where the display device 1 is used is stored in advance in a nonvolatile memory (not shown) provided in the display device 1 (for example, at the time of factory shipment). The display control unit 2a may read position information from the display device 1. In this case, the position information setting unit is configured by a non-volatile memory provided in the display device 1. When the display device 1 is composed of a portable display terminal having a wireless communication function, the display device 1 receives position information wirelessly transmitted from a wireless base station installed in each space, and the received position information Alternatively, it may be stored in the memory as position information indicating the current position. In this case, the position information setting unit is configured by a radio base station that is installed in each space and wirelessly transmits position information of the installed space.
