The lock control unit 53 is configured to control the locking unit 51 to switch the door 101 between a locked state and an unlocked state.

[0025] Next, the processing of the control system 1 according to this embodiment will be described. The processing of the control system 1 includes a reservation process and an unlocking process. The reservation process is performed when a user reserves the residential facility 100 as an accommodation facility. The unlocking process is performed when a user unlocks the smart lock 5 inside the residential facility 100.

[0026] First, the reservation process will be described. Hereinafter, as an example of the reservation process, a case where a user reserves the residential facility 100 as an accommodation facility using a mobile terminal owned by the user will be described. However, the reservation process is not limited to this example. The user can reserve the residential facility 100 as an accommodation facility using another device that can communicate with the server 4 instead of a mobile terminal.

[0027] 3 shows the sequence of reservation processing in the control system 1 according to the first embodiment. As shown in FIG. 3, first, a user inputs desired accommodation information into a mobile terminal (S1). The desired accommodation information includes information on the housing facility desired as the accommodation facility and desired accommodation schedule information. The user uses the mobile terminal to transmit the input desired accommodation information to the server communication unit 41 of the server 4 via the communication network N (S2).

[0028] When the server communication unit 41 receives the accommodation preference information transmitted from the mobile terminal, the server control unit 43 selects, from the information stored in the server storage unit 42, a residential facility candidate that matches the transmitted accommodation preference information (S3). There may be one or more residential facility candidates. The residential facility candidates selected by the server control unit 43 are transmitted from the server communication unit 41 to the mobile terminal (S4). If the user desires a room in one of the residential facility candidates 100 from the received residential facility candidates, the server control unit 43 generates residential facility determination information indicating this (S5). The user then inputs the user's name and address into the mobile terminal as required accommodation information (S6). The user transmits the generated residential facility determination information and the input required accommodation information to the server 4 (S7).

[0029] When the server control unit 43 receives the housing facility determination information and the required accommodation information from the mobile terminal, it generates reservation information based on the housing facility determination information and the required accommodation information (S8). The reservation information includes the user's name and address, housing facility information for the housing facility 100, and accommodation schedule information. The reservation information is, for example, a string of 10 or more alphanumeric characters. The generated reservation information is sent from the server communication unit 41 to the mobile terminal (S9). In this way, the user acquires the reservation information (S10). Furthermore, the generated reservation information is stored in the server storage unit 42 in association with the handset identification information of the handset 2 for the housing facility 100 desired by the user (S11). In this way, the reservation process is completed.

[0030] Next, the unlocking process will be described. 4 shows the sequence of the unlocking process of the control system 1 according to the first embodiment. First, the user goes to the residential facility 100 that has been reserved as an accommodation facility on the reserved accommodation date. As the entrance to the residential facility 100, a smart lock 5 is provided on the door 101 of the room, and a slave unit 2 is provided next to the door 101 (FIG. 1). The user inputs the reservation information acquired in the reservation process into the input unit 22 of the slave unit 2 (S31). When the user inputs the reservation information into the input unit 22, the slave unit 2 acquires the reservation information (S32).

[0031] The handset 2 transmits the input reservation information together with the handset identification information stored in the handset storage unit 25 from the handset communication unit 24 to the server 4 via the communication network N (S33).

[0032] The server 4 receives the reservation information and the handset identification information from the handset 2. Thereafter, the server control unit 43 determines whether or not the reservation information and the handset identification information received from the handset 2 match the reservation information and the handset identification information stored in the server storage unit 42 (S34). The server 4 may transmit the determination result determined by the server control unit 43 from the server communication unit 41 to the handset 2 via the communication network N.

[0033] If the server control unit 43 determines that the reservation information and handset identification information received from the handset 2 match the reservation information and handset identification information stored in the server memory unit 42, the server 4 transmits an unlocking signal from the server communication unit 41 to the lock communication unit 52 of the smart lock 5 via the communication network N (S35).

[0034] When the lock control unit 53 of the smart lock 5 receives the unlock signal from the server 4, it switches the door 101 from a locked state to an unlocked state (S36). This allows the user to open the door 101 of the residential facility 100 and enter the room. This completes the unlocking process.

[0035] As described above, according to the control system 1 of this embodiment, the door 101 of the residential facility 100 can be switched from a locked state to an unlocked state using the slave unit 2, which is an existing intercom device 10, and the server 4 installed in the residential facility 100. Therefore, it becomes easier to use at least a part of the residential facility 100 as an accommodation facility without introducing new equipment or machinery.

[0036] (Variation 1) In the unlocking process, in addition to checking the reservation information and the slave unit identification information, facial authentication of the user may be performed. As shown in Fig. 2, in the control system 1A according to the first modification, the slave unit 2 further includes a camera 23 capable of capturing an image of the face of the user. The slave unit control unit 26 is configured to also control the operation of the camera 23.

[0037] The server storage unit 42 stores image information including the user's face in association with reservation information and handset identification information.

[0038] Next, the reservation process of the control system 1A according to the modified example 1 will be described with reference to Fig. 3. In the reservation process of the control system 1A according to the modified example 1, the following process is performed in addition to S1 to S11 of the reservation process of the control system 1 according to the first embodiment.

[0039] After generating the housing facility determination information (S5), the user inputs the necessary accommodation information (S6) and also acquires image information including the user's face (S12). The user may acquire the image information by taking a picture of the user's face with the camera of the user's mobile device. The user may also acquire the image information by reading out image information including the user's face that is stored in the memory of the user's mobile device.

[0040] The user transmits the acquired image information to the server 4 (S13).

[0041] When the server control unit 43 receives the image information from the mobile terminal, it stores the received image information in association with the reservation information and the slave unit identification information (S14), thus completing the reservation process of the first modification.

[0042] Next, the unlocking process of the control system 1A according to the modified example 1 will be described with reference to Fig. 4. In the reservation process of the control system 1A according to the modified example 1, the following process is performed in addition to S31 to S36 of the reservation process of the control system 1 according to the first embodiment.

[0043] When a user inputs reservation information into the slave unit 2 (S31), the slave unit 2 takes a picture of the user's face with the camera 23 (S41). By taking a picture of the user's face with the camera 23, the slave unit 2 acquires image information of the user's face (S42).

[0044] In addition to transmitting the reservation information and the slave unit identification information (S33), the slave unit 2 transmits the acquired image information to the server 4 via the communication network N (S43).

[0045] The server 4 receives the reservation information, the handset identification information, and the image information from the handset 2. Thereafter, the server control unit 43 determines whether or not the reservation information, the handset identification information, and the image information received from the handset 2 match the reservation information, the handset identification information, and the image information stored in the server storage unit 42 (S34).

[0046] If the server control unit 43 determines that the reservation information, handset identification information, and image information received from the handset 2 match the reservation information, handset identification information, and image information stored in the server memory unit 42, the server 4 sends an unlocking signal to the smart lock 5 (S35).

[0047] When the smart lock 5 receives the unlock signal from the server 4, it switches the door 101 from the locked state to the unlocked state (S36). In this way, the unlocking process ends.

[0048] As described above, according to the control system 1A of this modified example, in addition to checking the reservation information against the slave unit identification information, image information including the user's face is also checked, thereby improving the security of the control system 1A.

[0049] Furthermore, the camera 23 of this modified example can also make it easier to input reservation information in the unlocking process (S31). For example, in S9 of the reservation process, the server 4 transmits a two-dimensional code to the user as the generated reservation information. The user acquires the two-dimensional code, which is the reservation information. The acquired two-dimensional code may be stored in the memory of the mobile terminal or may be printed on paper. In S31 of the unlocking process, when the user inputs the reservation information into the slave unit 2, the user holds the two-dimensional code, which is the reservation information acquired in the reservation process, over the camera 23 of the slave unit 2. The two-dimensional code that is held over the camera 23 may be a two-dimensional code displayed on the mobile terminal or a two-dimensional code printed on paper. When the camera 23 captures the two-dimensional code, the slave unit 2 acquires the reservation information based on the captured two-dimensional code (S32).

[0050] Since reservation information is a string of 10 or more alphanumeric characters, inputting the reservation information can be cumbersome for the user. However, instead of the user manually inputting the string of 10 or more alphanumeric characters directly into the handset 2, as in this modified example, the camera 23 can read a two-dimensional code as the reservation information, thereby reducing the cumbersomeness of inputting the reservation information.

[0051] (Variation 2) In the first embodiment and the first modification, the smart lock 5 is unlocked without the intervention of an administrator, but the unlocking process may be performed via an administrator. In the control system 1B according to the second modification, the administrator responds to a call from the slave 2 and performs the unlocking process.

[0052] The processing of the control system 1B according to Modification 2 will be described. The reservation processing of the control system 1B according to Modification 2 is the same as the reservation processing of the control system 1 according to the first embodiment, so the description will be omitted. The unlocking processing of the control system 1B according to Modification 2 will be described with reference to FIG. 5. In the unlocking processing of the control system 1B according to Modification 2, the following processing is performed before S31 of the unlocking processing of the control system 1 according to the first embodiment.

[0053] 5 shows the sequence of the unlocking process of the control system 1B according to the second modification. First, the user goes to the residential facility 100 that has been reserved as an accommodation facility on the reserved date and places a call from the handset 2 to the base unit 3 (S51). The user may make the call by activating the microphone of the communication unit 21 of the handset 2, or by pressing the call button. When the user makes the call from the handset 2, a call signal is transmitted from the handset communication unit 24 of the handset 2 to the base unit communication unit 31 of the base unit 3 (S52).

[0054] When the base unit 3 receives a call signal from the handset 2, the manager answers the call from the handset 2 (S53). For example, when the base unit 3 receives a call signal from the handset 2, the microphone and speaker of the base unit communication unit 33 are activated, allowing the manager to talk to the user. The manager asks the user about the requirements for the call via the handset 2, which can now talk to the base unit 3. When the manager receives confirmation from the user that they would like to use the housing facility 100 as an accommodation facility and that the reservation process has been completed, the manager requests reservation information from the user (S54). For example, the manager prompts the user to input the reservation information obtained in the reservation process into the input unit 22 of the handset 2.

[0055] When the user receives a request for reservation information from the administrator, the user inputs the reservation information into the input unit 22 of the slave unit 2 (S31). When the user inputs the reservation information into the input unit 22, the slave unit 2 acquires the reservation information (S32).

[0056] The handset 2 transmits the input reservation information together with the handset identification information stored in the handset storage unit 25 from the handset communication unit 24 to the base unit communication unit 31 via the communication network N (S55).

[0057] The base unit 3 receives the reservation information and the handset identification information from the handset 2. Thereafter, the base unit communication unit 31 transmits the reservation information and the handset identification information received from the handset 2 to the server 4 via the communication network N (S56).

[0058] The server 4 receives the reservation information and the child device identification information from the base unit 3. Thereafter, the server control unit 43 determines whether the reservation information and the child device identification information received from the base unit 3 match the reservation information and the child device identification information stored in the server storage unit 42 (S34).

[0059] If the server control unit 43 determines that the reservation information and sub-unit identification information received from the parent unit 3 match the reservation information and sub-unit identification information stored in the server memory unit 42, the server 4 sends an unlocking signal to the smart lock 5 (S35).

[0060] When the smart lock 5 receives the unlock signal from the server 4, it switches the door 101 from the locked state to the unlocked state (S36). In this way, the unlocking process ends.

[0061] As described above, according to the control system 1B of this modified example, the unlocking process is performed with the intervention of an administrator, and therefore the security of the control system 1B is improved.

[0062] (Variation 3) In the first embodiment to the second modification, the server 4 collates the reservation information and the handset identification number, but the base unit 3 may collate the reservation information and the handset identification number. In the control system 1C according to the third modification, the base unit storage unit 32 of the base unit 3 stores the base unit identification information in association with the handset identification information of the handset 2 that can communicate with the base unit 3 and the reservation information. Furthermore, in the control system 1C, the base unit control unit 34 of the base unit 3 is configured to determine whether the information transmitted via the communication network N matches the information stored in the base unit storage unit 32. The base unit control unit 34 is an example of a control unit of the control system 1C according to the third modification.

[0063] Next, the reservation processing of the control system 1C according to the modified example 3 will be described with reference to Fig. 3. The reservation processing of the control system 1C according to the modified example 3 also performs the processes from S1 to S9 of the reservation processing of the control system 1 according to the first embodiment.

[0064] The server 4 transmits the generated reservation information to the user's mobile terminal (S9). The server 4 then transmits the generated reservation information to the base unit 3 that can communicate with the handset 2, together with the handset identification information of the handset 2 of the housing facility 100 selected by the user (S15). The base unit 3 stores the received reservation information and handset identification information in the base unit storage unit 32, associating them with each other (S16). This completes the reservation process.

[0065] Next, the unlocking process of the control system 1C according to Modification 3 will be described with reference to Fig. 6. Fig. 6 shows the sequence of the unlocking process of the control system 1C according to Modification 3. The unlocking process of the control system 1C according to Modification 3 also performs steps S31 to S33 of the unlocking process of the control system 1 according to the first embodiment.

[0066] When the server 4 receives the reservation information and the handset identification information from the handset 2, the server 4 transmits the received reservation information and the handset identification information from the server communication unit 41 to the base unit 3 via the communication network N (S61).

[0067] The base unit 3 receives the reservation information and the handset identification information from the server 4. Thereafter, the base unit control unit 34 determines whether the reservation information and the handset identification information received from the server 4 match the reservation information and the handset identification information stored in the base unit storage unit 32 (S62). The base unit 3 transmits the determination result made by the base unit control unit 34 from the base unit communication unit 31 to the server 4 via the communication network N (S63).

[0068] The server 4 receives and acquires the determination result from the master unit 3 (S64). If the acquired determination result indicates that the reservation information and slave unit identification information acquired by the slave unit 2 match the reservation information and slave unit identification information stored in the master unit storage unit 32, the server 4 transmits an unlock signal to the smart lock 5 (S35).

[0069] When the smart lock 5 receives the unlock signal from the server 4, it switches the door 101 from the locked state to the unlocked state (S36). In this way, the unlocking process ends.

[0070] As described above, according to the control system 1C of this modified example, the base unit 3 collates the reservation information with the handset identification information, so that the door 101 of the residential facility 100 can be switched from a locked state to an unlocked state using the existing intercom device 10, which is the handset 2, the base unit, and the server 4. Therefore, it becomes easier to use part of the residential facility 100 as an accommodation facility without introducing new equipment or machinery.

[0071] In the first embodiment and Modifications 1 to 3, the control system has been described as being used in a detached house as an example of the residential facility 100, but the residential facility 100 is not limited to a detached house. The residential facility 100 may also be an apartment building. When the control system is used in an apartment building as the residential facility 100, the slave unit 2 is configured as a collective entrance unit installed at the apartment building's collective entrance, and the smart lock 5 is configured to control the locking and unlocking of the door installed at the collective entrance. Even when used in such an apartment building, the control system of the present disclosure achieves the above-described effects.

[0072] In the first embodiment and Modifications 1 to 3, intercom device 10 is configured with handset 2, base unit 3, and server 4, and handset 2, base unit 3, and server 4 are each provided as separate devices, but the configuration of the control system is not limited to this. For example, the control system may include a single control device in which base unit 3 and server 4 are integrated. In other words, the control unit of the control device may be configured by integrating base unit control unit 34 and server control unit 43 of base unit 3, and the control unit of the control system may determine whether received information matches stored information. As another example, handset control unit 26 of handset 2 may determine whether received information matches stored information. [Explanation of symbols]
