However, the image recognition unit 14 may be provided in the lobby terminal 7, and as long as the purpose can be achieved, It may be provided anywhere in the residential network system.

  In addition, when the resident of the dwelling units 3a and 3b is absent, the video of the visitor photographed by the camera of the lobby terminal 7 is transmitted by e-mail to the mobile phone of the resident of the dwelling units 3a and 3b by the center server 1. You can also make it.

  Hereinafter, with reference to the flowchart shown in FIG. 3, the operation | movement of the network system for housing complexes which concerns on embodiment is explained in full detail.

  First, when the visitor A visits, the resident of the dwelling unit 3a in advance sends the e-mail address and phone number of the mobile phone 6 as the address information of the mobile phone 6 held by the visitor A to the communication device 5a. The valid information that defines the number of times of use of the identification information and the valid period of the visitor identification information is input, and the communication device 5a transmits the information to the center server 1 via the central monitoring panel 9 and is the dwelling unit identification information. The ID information of the resident of the dwelling unit 3a and the device information of the interphone 4a are also automatically transmitted to the center server 1 (S101). Here, the visitor identification information is used once.

  When the center server 1 receives the address information of the mobile phone 6 from the communication device 5a, the valid information, and the dwell unit identification information as the password generation information, first, the center server 1 first stores the dwell unit number associated with the dwell unit identification information and registered. It is set as a password (S102).

  At the same time, the center server 1 creates visitor identification information (S103). Here, when creating the visitor identification information, the center server 1 creates the visitor identification information by using a random number in the random number generation unit 11 as necessary, or converts the visitor identification information into image data. Or process it.

  Then, the center server 1 associates the personal identification number with the visitor identification information and the valid information into a database and stores it in the storage unit 10 (S104).

  Further, the center server 1 transmits visitor identification information to the mobile phone 6 by e-mail or telephone based on the address information of the mobile phone 6 (S105).

  Next, the mobile phone 6 held by the visitor A receives visitor identification information from the center server 1. (S106). Here, the mobile phone 6 can also receive valid information from the center server 1, and the visitor A can check the valid information on the liquid crystal screen of the mobile phone 6 as appropriate.

  Further, a personal identification number is separately transmitted to the visitor A (S107).

  Then, the visitor A possesses the mobile phone 6 that has received the visitor identification information at the visit, and inputs the visitor identification information to the input receiving unit 13 of the lobby terminal 7 (S108). Specifically, if the visitor identification information is composed of a numeric string, it is input by a numeric keypad, and if it is composed of an image, it is photographed by a camera.

  The visitor A inputs a personal identification number using the numeric keypad (S109).

  Thereafter, the lobby terminal 7 transmits the entered visitor identification information and password to the center server 1 via the central monitoring board 9 (S110).

  When the center server 1 receives the visitor identification information and the personal identification number from the lobby terminal 7, the center server 1 compares the received visitor identification information and personal identification number with the stored visitor identification information and personal identification number. And whether the received visitor identification information is within the range of the usage rule is referred to (S111). At this time, if the visitor identification information is composed of images, the center server 1 analyzes the visitor identification information by the decoding function of the image recognition unit 14. If the image recognition unit 14 is provided in the lobby terminal 7, the visitor identification information composed of images is analyzed in S110.

  The center server 1 receives the received visitor identification information and dwelling unit number when the stored visitor identification information and personal identification number coincide with each other and as a result of referring to the stored valid information. When the visitor identification information is within the usage regulation range, the lock of the automatic lock door 8 is unlocked via the central monitoring panel 9. (S112).

  Then, the center server 1 cannot use the visitor identification information thereafter (S113).

  On the other hand, if the visitor identification information input to the lobby terminal 7 does not satisfy the above condition, the lock of the automatic lock door 8 is not unlocked, and the process ends (S114).

  Finally, if the center server 1 confirms that the visitor A has opened / closed the auto-lock door 8 or that the predetermined period has elapsed even if the auto-lock door 8 has not been opened / closed, The automatic lock door 8 is locked (S115).

  In S114, when the process is terminated without unlocking the automatic lock door 8, the center server 1 may notify the visitor A of the fact. Specifically, for example, a liquid crystal screen is provided in the lobby terminal 7 and the center server 1 displays that on the liquid crystal screen.

  By the way, when the visitor unlocks the lock of the auto-lock door 8, the center server 1 may notify the residents of the dwelling units 3a and 3b by the interphones 4a and 4b.

  When the personal identification number is arbitrarily designated, first, the communication devices 5a and 5b receive the personal identification number input by the residents of the dwelling units 3a and 3b, the address information of the mobile phone 6, and valid information as necessary. 1 as well as the dwelling unit number or dwelling unit identification information is automatically transmitted to the center server 1.

  Upon receiving these pieces of information, the center server 1 creates visitor identification information, and stores the dwelling unit number or dwelling unit identification information, the personal identification number, the visitor identification information, and valid information as necessary in association with each other in the storage unit 10. At the same time, visitor identification information is transmitted to the mobile phone 6 based on the address information.

  Thereafter, when the visitor identification information and the password are input by the visitor, the lobby terminal 7 transmits the visitor identification information and the password to the center server 1.

  When the center server 1 receives the visitor identification information and the personal identification number from the lobby terminal 7, the center server 1 compares the received visitor identification information and personal identification number with the stored visitor identification information and personal identification number. If the visitor identification information is within the range of the usage rules as a result of referring to the stored valid information, the lock of the automatic lock door 8 is unlocked. Based on the stored dwelling unit number or dwelling unit identification information, the visitor is notified to the dwellers of the dwelling units 3a and 3b by the interphones 4a and 4b.

  If the above-described configuration is adopted, the residents of the dwelling units 3a and 3b can see that the visitor identification number requested by the center server 1 to be used is used. Security level is improved. Moreover, since the resident of the dwelling units 3a and 3b knows that the visitor will come to the dwelling units 3a and 3b without passing through the common entrance, he can prepare for the visit of the visitor.

  Therefore, the two responses to the visitor that the resident had to make and the two calls to the resident that the visitor had to make can be reduced to one time, and both the resident and the visitor have to do it. Even if an unexpected situation occurs for residents, such as theft of visitor identification information, by allowing visitors to enter their passwords, the password is not known except for legitimate visitors. Since the lock of the auto-lock door 8 provided in the 2 common entrance cannot be unlocked, it is possible to prevent the security level of the apartment house 2 from being lowered. Further, since the personal identification number is automatically created by the center server 1, it is possible to save the trouble of designating the personal identification number.
