A-2. Processing flow of communication system 500:
FIG. 8 shows that the trigger information is condition No. 1 is a processing procedure executed by the communication system 500 when 1 is satisfied. First, when the security sensor 42 reacts, the security sensor 42 transmits alarm information as trigger information to the router 20 (step S102). After the router 20 acquires the trigger information, the event determination unit 221 (FIG. 2) determines whether the trigger information satisfies one of the predetermined condition groups (Step S104). In the case of FIG. 8, since the trigger information is alarm information, the event determination unit 221 determines that the trigger information is condition No. It is determined that 1 is satisfied. If the information received by the router 20 does not correspond to the conditions specified in the condition table 243, the communication system 500 stops the process without performing the subsequent processes.

Next, the related information acquisition unit 225 receives the condition No. The related command corresponding to 1 is specified by referring to the related command table 245 (step S106). Next, the related information acquisition unit 225 transmits the related command specified via the communication unit 26 to the target device 40 (steps S108 and S110). First, the related information acquisition unit 225 transmits a command to turn on the fluorescent lamp (illumination ON command) to the first lighting fixture 43 (step S108). Next, the 1st lighting fixture 43 which received and performed the illumination ON command returns ACK with respect to the router 20 (step S109). Next, the related information acquisition unit 225 transmits a command (shooting command) for shooting an image to the WEB camera 47 (step S110). The WEB camera 47 that has executed the shooting command returns an ACK to the router 20 (step S112). In this ACK, browsing destination information (for example, URL information) of an image taken by the WEB camera 47 is added as related information .

After the router 20 acquires the trigger information and the related information, the message generator 227 refers to the message table 241 and generates an SNS message (step S114). In the case of FIG. 8, the message generation unit 227 has a condition No. The SNS message form corresponding to 1 is selected from the message table 241 (FIG. 5). Then, the message generation unit 227 generates an SNS message by inputting browsing URL information (related information) of an image captured by the WEB camera 47 to the selected SNS message form.

  Next, the SNS message generation unit 227 transmits the generated SNS message to the SNS server device 30 via the communication unit 26 (step S116). The SNS server device 30 stores the received SNS message in the message storage unit 341 (FIG. 7) (step S118). When there is an SNS message acquisition request from the communication terminal 70 to the SNS server device 30 (step S120), the SNS server device 30 transmits the stored SNS message addressed to the communication terminal 70 to the communication terminal 70 (step S122). ). The user of the communication terminal 70 uses the touch panel 73 to check the condition No. By browsing the SNS message corresponding to 1 (FIG. 5), it is possible to know that the security sensor 42 has reacted and to view an indoor image. That is, the user can obtain the determination material for determining the cause of the reaction of the security sensor 42 from the image information. The SNS message acquisition request (step S120) is repeatedly transmitted from the communication terminal 70 to the router 20 at predetermined intervals. The same applies to SNS message acquisition requests in other processing procedures described below.

FIG. 9 shows that the trigger information is condition No. 2 is a processing procedure executed by the communication system 500 when the condition 2 is satisfied. When the printer 45 detects ink out, it transmits ink out information, which is trigger information, to the router 20 (step S142). After the router 20 acquires the trigger information, the event determination unit 221 (FIG. 2) determines whether the trigger information satisfies one of the predetermined condition groups (Step S144). In the case of FIG. 9, since the trigger information is ink out information, the event determination unit 221 determines that the trigger information is condition No. It is determined that 2 is satisfied.

Next, the related information acquisition unit 225 receives the condition No. The paper information acquisition command is specified as a related command corresponding to 2 by referring to the related command table 245 (step S146). Next, the related information acquisition unit 225 transmits a paper information acquisition command to the target printer 45 (step S148). Printer 45 that has received the paper information acquisition command transmits the information representing the degree of consumption of the paper information representing the (relevant information) as residual paper (paper remaining amount information) to the router 20 (step S150).

After the router 20 acquires the trigger information (ink out information) and the related information (paper remaining amount information), the message generator 227 refers to the message table 241 and generates an SNS message (step S154). For Figure 9, condition message generator 227, the condition is satisfied by the trigger information No. 2 is selected from the message table 241 (FIG. 5). The message generation unit 227 generates an SNS message by inputting a numerical value of the remaining amount of paper obtained from the remaining amount of paper information as related information to the selected SNS message form. Steps S156 to S162 are the same as steps S116 to S122 in FIG. As described above, when one of the target devices 40 includes a plurality of consumables, the information indicating the replacement time of one consumable is used as a trigger, in addition to the replacement time of one consumable, the consumption of other consumables. An SNS message representing the degree is generated by the router 20. Thereby, the user can grasp | ascertain the extent of consumption of several consumables at a time by browsing an SNS message.

FIG. 10 shows that the trigger information is condition No. 3 is a processing procedure executed by the communication system 500 when the condition 3 is satisfied. When detecting that the fluorescent lamp has reached the end of its life, the first lighting fixture 43 transmits fluorescent lamp burnout information, which is trigger information, to the router 20 (step S172). After the router 20 acquires the trigger information, the event determination unit 221 (FIG. 2) determines whether the trigger information satisfies one of the predetermined condition groups (Step S174). In the case of FIG. 10, since the trigger information is fluorescent lamp burnout information, the event determination unit 221 determines that the trigger information is condition No. It is determined that 3 is satisfied.

Next, the related information acquisition unit 225 receives the condition No. As a related command corresponding to 3, refer to the related command table 245 for a command (fluorescent lamp information acquisition command) for acquiring information (related information) indicating the degree of consumption of the fluorescent lamp included in the second lighting fixture 44. This is specified (step S176). Next, the related information acquisition unit 225 transmits a fluorescent lamp information acquisition command to the second lighting fixture 44 (step S178). The second lighting fixture 44 that has received the fluorescent lamp information acquisition command transmits the total ON time of the fluorescent lamp to the router 20 as information (related information) indicating the degree of consumption of the fluorescent lamp (step S180).

  After the router 20 acquires trigger information (fluorescent lamp burnout information) and related information (total ON time information), the message generator 227 refers to the message table 241 and generates an SNS message (step S184). In the case of FIG. 10, the message generation unit 227 displays the condition No. The SNS message form corresponding to 3 is selected from the message table 241 (FIG. 5). The message generation unit 227 generates an SNS message by inputting the ON time value obtained from the total ON time information for the selected SNS message form. Steps S186 to S192 are the same as steps S116 to S122 in FIG. As described above, the SNS message representing the total ON time information of the second lighting fixture 43 is added to the router in addition to the fluorescent lighting cutoff information of the first lighting fixture 43 by using the fluorescent lighting cutoff information of the first lighting fixture 43 as a trigger. 20 is generated. Thereby, the user can grasp | ascertain the grade of the consumables with which the different object apparatus 40 is provided at a time by browsing an SNS message.

As described above, according to the first embodiment, it is possible to easily notify the user of the trigger information and the related information of the target device using the SNS that is widely spread. The router 20 is not only trigger information of the target device, from Rukoto generate an SNS message corresponding to both the trigger information and related information, user related information in addition to the trigger information may be grasped at the same time. The router 20 includes a message table 241 that uniquely defines each condition (conditions No. 1 to No. 4) of a predetermined condition group and the form of the SNS message (FIG. 5). Accordingly, the router 20 can easily generate an SNS message by referring to the message table 241. Further, in the predetermined condition group, the condition No. 2-No. 4, the trigger information defines a Dearuko information indicating when to replace consumables of the target device 40 as a condition (Fig. 4). Thereby, since the SNS message can be generated using the replacement time of the consumables of the target device 40 as a trigger, it is possible to reliably notify the user of the replacement time of the consumables.

B. Second embodiment:
FIG. 11 is a diagram for explaining a communication system 500a as the second embodiment of the present invention. The difference from the communication system 500 of the first embodiment is that the location information server device 80 is provided, the internal configuration of the router 20a, and the internal configuration of the communication terminal 70a. Since the other configuration is the same as that of the first embodiment, the same reference numeral is assigned to the same configuration and the description thereof is omitted.

The communication system 500a further includes a location information server device 80. A GPS (Global Positioning System) receiver 724 included in the communication terminal 70a acquires position information representing the current position of the communication terminal 70a at predetermined intervals. The acquired position information is transmitted to the position information server device 80. The transmitted position information is stored in the position information server device 80 together with the acquisition time. The location information server device 80 further stores map information including location information of the user of the communication terminal 70a at home and location information of a home appliance mass retailer.

FIG. 12 is an internal block diagram of the router 20a of the second embodiment. The difference from the router 20 (FIG. 2) of the first embodiment is that a new location information acquisition unit 222 is provided and the contents of the condition table 243a. The position information acquisition unit 222 acquires the position information of the communication terminal 70a from the position information server device 80 at predetermined intervals.

  FIG. 13 is a diagram for explaining the condition table 243a. The condition table 243a is a table that defines a predetermined condition group. Each condition of the predetermined condition group includes a device-side condition regarding the target device and a position condition regarding the position information of the communication terminal 70 a registered in the SNS server device 30. Condition No. 1a-No. The content of the device side condition of 4a is the condition No. of the condition table 243 (FIG. 3). 1-No. Since it is the same as the condition content of 4, description is abbreviate | omitted. Condition No. The content of the position condition 1a is that the position represented by the position information of the communication terminal 70a is at least a predetermined distance from the home of the user of the communication terminal 70a. Condition No. 2a-No. The content of each position condition 4a is that the position represented by the position information of the communication terminal 70a is within a predetermined distance from the home appliance mass retailer.

  The message table 241a and the related command table 245a shown in FIG. 12 are respectively associated with the condition numbers associated with the message table 241 and the related command table 245 shown in FIGS.

  FIG. 14 shows that the trigger information is condition No. This is a processing procedure executed by the communication system 500a when 1a is satisfied. The security sensor 42 transmits alarm information which is a part of the trigger information to the router 20 (step S102). The router 20a that has received the alarm information acquires the latest position information of the communication terminal 70a from the position information server device 80 (step S103). This position information forms part of the trigger information.

After the router 20 acquires the trigger information ( alarm information and position information ) , the event determination unit 221 (FIG. 12) determines whether the trigger information satisfies one of the predetermined condition groups (step S104a). In the case of FIG. It is determined that 1a is satisfied. The processing in steps S106 to S122 is similar to the processing in steps S106 to S122 in FIG. Similarly to FIG. 14, when the ink out information and the fluorescent lamp out information are acquired from the target device 40, the processing after step S146 shown in FIG. 9 after the step S103 or the processing shown in FIG. The communication system 500a executes the processing after step S176.

In the present embodiment, a security sensor 42, a first lighting fixture 43, a television 48, a recorder 49, and a WEB camera 47 are defined as devices for controlling operations. The second table Ta2 stores an SNS message that can be transmitted for each target device. For example, when the target device is the television 48, “power ON”, “power OFF”, “program recording reservation”, etc. are defined as SNS messages. Further, an identification number (No.) is added to each SNS message. Each SNS message is transmitted to the SNS server device 30 with the router 20b as a destination.

  First, the first table Ta1 is displayed on the touch panel 73 of the communication terminal 70b. When the user selects any of the target devices 40, a second table Ta2 of the selected target devices is displayed. When the user selects “program recording reservation” in the second table Ta2, a screen (for example, a program guide) for specifying a program desired to be recorded is further displayed.

  FIG. 17 is an internal block diagram of the router 20b of the third embodiment. A difference from the router 20 (FIG. 2) of the first embodiment is that a new message acquisition unit 228 and an operation specifying unit 220 are provided as functional units of the CPU 22, and a second message table is newly added to the storage unit 24. 244, a second related command table 249, a command table 242, and a target device specification table 246 are stored. The first message table 241 is the same as the message table 241 of the first embodiment, and the first related command table 245 is the same as the related command table 245 of the first embodiment. The message acquisition unit 228 transmits an SNS message acquisition request to the SNS server device 30 at predetermined intervals. Then, the message acquisition unit 228 acquires an SNS message addressed to the router 20 b stored in the SNS server device 30 from the SNS server device 30. The target device specification table 246 stores specification data indicating the type of the target device 40 and the like.

  The operation specifying unit 220 includes a command specifying unit 220a, an operation determining unit 220b, and an alternative device specifying unit 220c. The command specifying unit 220a refers to the command table 242 based on the acquired SNS message. And the command specific | specification part 220a specifies the specific target apparatus which should control operation | movement from the some target apparatus 40, and the control command for controlling operation | movement of a specific target apparatus. Further, the command specifying unit 220a transmits a control command to the specific target device via the communication unit 26 by issuing a transmission command to the communication control unit 229. The operation determination unit 220b determines whether the specific target device can execute the control command. Specifically, the operation determination unit 220b acquires information (for example, storage capacity and executable content information) for executing the control command from the specific target device, and determines whether the control command can be executed. The alternative device specifying unit 220c can execute a control command from a plurality of target devices 40 with reference to the target device specification table 246 when it is determined that the specific target device cannot execute the control command based on the determination information. The target device is identified as an alternative device. Further, the substitute device specifying unit 220c sends a control command to the substitute device via the communication unit 26 by issuing a transmission command to the communication control unit 229.

  FIG. 18 is a diagram for explaining the command table 242. The command table 242 is a table that uniquely defines a terminal message, a control command, and a specific target device. “Terminal message No.” corresponds to “Terminal message No.” in FIG. Terminal message No. 1A to 3B, 4A, 4B, 5A, and 5B generate a control command for switching ON / OFF the power of the specific target device. For example, the router 20b receives the terminal message No. When 1A is acquired, the command specifying unit 220a (FIG. 1) specifies the security sensor 42 as the specifying target device, and specifies the control command “AABBC” for turning on the power as the control command. Terminal message No. 3C and 4C generate control commands for program recording reservation. For example, the router 20b receives the terminal message No. When 3C is acquired, the command specifying unit 220a specifies the television 48 as the specifying target device, and specifies the control command “BADAD” for recording the designated program as the control command.

  FIG. 19 is a diagram for explaining the second related command table 249. The second related command table 249 is associated with the terminal message and command table 242 in advance. Terminal message No. Related commands are not defined in 1A, 1B, 3A to 4C, and 5B. That is, the command specifying unit 220a (FIG. 17) displays the terminal message No. When 1A, 1B, 3A-4C, and 5B are acquired, the command target 242 and the control command are specified with reference to the command table 242 (FIG. 18), and the second related command table 249 is referred to. Check other related commands. The control command specified in the second related command table 249 is executed after the control command specified in the command table 242 is executed.

  Terminal message No. Related commands are defined for 2A, 2B, 5A, and 5C. For example, the terminal message No. In the case of 2A, “No. 5C” is defined as the related command. This “No. 5C” is the terminal message No. of the command table 242. It corresponds to. That is, when “No. 5C” is defined as the related command, the control command “DAABB” for starting the photographing with respect to the WEB camera 47 becomes the related command. The command specifying unit 220a refers to the command table 242 and the second related command table 249 based on the terminal message, and generates a related command in addition to the control command when the related command exists.

  FIG. 20 is a diagram for explaining the second message table 244. The second message table 244 includes the terminal message No. specified in the command table 242. And an SNS message form. The message generator 227 indicates that the terminal message is No. In the case of any one of 1A to 5C, the SNS message is generated by referring to the second message table 244. The second message table 244 determines that the specific target device cannot execute at least part of the control command when the operation determination unit 220b determines that the specific target device can execute the control command (when ACK is received). The SNS message form has a different part in the case where the SNS message is received (when the NACK is received). For example, the router 20b receives the terminal message No. If it is determined that the program recording designated by the user can be executed by the television 48, the terminal message No. 3C is acquired. An SNS message is generated using an SNS message form of 3C (ACK). On the other hand, if it is determined that the designated program recording cannot be executed by the television 48 and if the designated program recording is executed by another alternative device, the terminal message No. An SNS message is generated using an SNS message form of 3C (NACK-1). When there are two designated program recordings, the router 20b can execute terminal message No. 1 when one of the program recordings can be performed by the television 48 and the other program recording can be performed by another alternative device. An SNS message is generated using an SNS message form of 3C (NACK-2).

FIG. 21 is an example of a processing procedure executed by the communication system 500b when the terminal message is acquired by the router 20b. In FIG. 21, the message No. The processing procedure of the communication system 500b when the router 20b acquires 2A (FIG. 16) is shown. First, the communication terminal 70b receives a terminal message No. The 2A SNS message is transmitted to the SNS server device 30 (step S202). The SNS server device 30 stores the received SNS message in the message storage unit 341 (FIG. 7) (step S203). When there is an SNS message acquisition request from the router 20b to the SNS server device 30 (step S204), the SNS server device 30 transmits the stored SNS message addressed to the router 20b to the router 20b (step S206). . After the router 20b acquires the terminal message that is an SNS message, the command specifying unit 220a refers to the command table 242 and the second related command table 249, and the target device (specific target device) 40 that controls the operation A control command is identified (step S208). In the case of the example shown in FIG. 21, the command specifying unit 220a specifies the first lighting fixture 43 as the specifying target device and specifies the power ON command as the control command. Next, the router 20b transmits a control command (power ON command) to the first lighting fixture 43 (step S210). The first lighting fixture 43 that has executed the power ON command returns ACK (trigger information) to the router 20b (step S212) . After receiving the ACK for the power ON command, the router 20b transmits a control command (imaging command) to the WEB camera 47 (step S216). The WEB camera 47 that has executed the shooting command returns an ACK to the router 20b (step S218). In the ACK returned by the WEB camera 47, browsing destination information (for example, URL information) of an image taken by the WEB camera 47 is added as related information .

  After acquiring the ACK from the target device 40 that has transmitted the control command, the message generator 227 refers to the second message table 244 to generate an SNS message (step S220). In the case of FIG. 21, the message generator 227 displays the terminal message No. The SNS message form corresponding to 2A is selected from the second message table 244 (FIG. 20). Then, the message generation unit 227 generates an SNS message by inputting browsing destination URL information of an image captured by the WEB camera 47 to the selected SNS message form. The processing in steps S224 to S232 shown in FIG. 21 is the same as the processing in steps S116 to S122 in FIG. According to the processing procedure of FIG. 22, the user can grasp other information previously associated with the terminal message by the SNS message.

  FIG. 22 is another example of a processing procedure executed by the communication system 500b when the router 20b acquires a terminal message. In FIG. 22, the message No. No. The processing procedure of the communication system 500b when the router 20b acquires 3C (FIG. 16) is shown. First, the communication terminal 70b receives a terminal message No. The 3C SNS message is transmitted to the SNS server device 30 (step S302). Terminal message No. In 3C, it is assumed that two different programs in the same time period are specified by the user.

The SNS server device 30 stores the received SNS message in the message storage unit 341 (FIG. 7) (step S303). If there is SNS message acquiring request from the router 20b against SNS server device 30 (step S304), SNS server device 30 transmits the SNS messages stored router 20b destined to the router 20b (Step S 3 06). After the router 20b acquires the terminal message that is an SNS message, the command specifying unit 220a refers to the command table 242 and the second related command table 249, and the target device (specific target device) 40 that controls the operation A control command is identified (step S 3 08). In the case of the example shown in FIG. 22, the command specifying unit 220a specifies the television 48 as the specifying target device, and specifies a control command (recording reservation command) for recording two programs specified as control commands. Next, the router 20b transmits a control command (recording reservation command) to the television 48 (step S310). If the control command cannot be executed for the control command acquired by the television 48, a NACK is transmitted to the router 20b (step S312). Information (trigger information) indicating that only one program can be recorded is added to the NACK.

  After receiving NACK, which is determination information, the operation determination unit 220b (FIG. 17) determines that a recording reservation command for recording two programs cannot be executed depending on the television 48 (step S313). Note that if ACK is transmitted in step S312, the operation determination unit 220b does not perform processing for specifying an alternative device.

In Step S313, when it is determined that the specific target device cannot execute at least a part of the control command (trigger information satisfies the condition) , the alternative device specifying unit 220c selects the remaining control commands (from the plurality of target devices 40). The target device 40 that can execute the other program recording reservation) is specified as an alternative device (step S314). In the example shown in FIG. 22, the alternative device specifying unit 220c specifies the other recorder 49 that can be reserved for program recording as an alternative device with reference to the target device specification table 246 (FIG. 17).

After step S314, the command specifying unit 220a generates the control command specified in step S308 by dividing it into two commands, transmits a control command for executing one program recording reservation to the television 48, and transmits the other program. A control command for executing recording reservation is transmitted to the recorder 49 (steps S318 and S322). As a response to each control command, the television 48 and the recorder 49 transmit ACK (related information) to the router 20b (steps S320 and S324).

  After acquiring ACK from the television 48 and the recorder 49, the message generator 227 refers to the message table 241 and generates an SNS message (step S322). In the example shown in FIG. An SNS message corresponding to 3C (NACK-2) is generated (FIG. 20).

  If the NACK transmitted from the television 48 to the recorder 49 in step S312 includes information indicating that all the recording reservation commands for recording two programs cannot be executed, the recorder 49 is replaced with an alternative device in step S314. As specified. Then, a recording reservation command for recording two programs is transmitted to the recorder 49.

  Thus, according to the said 3rd Embodiment, in addition to the effect which the communication system 500b of 1st Embodiment has, there exist the following effects. In other words, the operation of the specific target device can be controlled based on the terminal message, and the user can easily grasp that the control command is transmitted to the specific target device by the SNS message. Further, even when the specified target device cannot execute the control command specified based on the terminal message, it is possible to cause the substitute device to execute all or some of the control commands. Thereby, the control command can be executed more reliably. In addition, the router 20b of the present embodiment has a NAT (Network Address Translation) function, and a private address assigned to each of a plurality of target devices 40 connected to the LAN side and an IP address on the WAN side Address conversion is performed between Here, when the communication terminal 70b transmits a command such as a terminal message directly from the WAN side of the router 20b to any of the target devices 40, the router 20b is not clear of the private address of the target device that is the transmission destination. The target device 40 cannot be operated beyond the router 20b. A so-called NAT traversal problem occurs. In the present embodiment, the terminal device 70b transmits a terminal message to the SNS server device 30 instead of the router 20b, and the router 20b acquires a message from the SNS server device 30, so the target device 40 (operation target) The device 40) can be specified. Further, since the command is transmitted from the router 20b to the operation target device 40, the NAT traversal problem can be solved.
